Immunology & Immunotherapy of Urologic Cancers 18 Eric J Small, MD Both experimental and naturally occurring tumors are capable of stimulating a specific antitumor immune response This observation suggests that there are foreign proteins (antigens) on tumor cells that classically have been described as resulting in humoral and cellular immune responses However, experimental models suggest that a Tcell (cell-mediated) response may be more important in the killing of tumor cells than a B-cell (humoral) response A detailed description of the components of the immune system is beyond the scope of this chapter, but certain features of the immune system as they pertain to diagnostic and therapeutic issues will be reviewed to the specific antigen The mechanisms of tolerance are complex and may be due in part to the absence of other required costimulatory molecules (such as B7, a molecule required for T-cell stimulation) The development of monoclonal (hybridoma) technology has allowed the development of many antibodies against many tumor-associated antigens and has provided insight into the regulation and expression of these antigens The reexpression or upregulation of these tumorassociated antigens during carcinogenesis may lead to immune response (or loss of tolerance) Many novel therapeutic approaches have sought to break this tolerance, and approaches to enhance a patient’s immune response will be discussed Tumor Antigens Tumor antigens can be divided into tumor-specific antigens and tumor-associated antigens Tumor-specific antigens are not found on normal tissue, and they permit the host to recognize a tumor as foreign Tumor-specific antigens have been shown to exist in oncogenesis models utilizing chemical, physical, and viral carcinogens but appear to be less common in models of spontaneous tumor development The identification of tumor-specific antigens led to the theory of immune surveillance, which suggests that the immune system is continuously trolling for foreign (tumorspecific) antigens This theory is supported by the observation that at least some cancers are more common in immune-suppressed patients such as transplant patients or human immunodeficiency virus-infected individuals However, many cancers are not overrepresented in these patient populations Furthermore, spontaneous tumor models, which more closely resemble human carcinogenesis, appear to have a less extensive repertoire of tumor-specific antigens but instead have been found to express many tumorassociated antigens Tumor-associated antigens are found on normal cells but either become less prevalent in normal tissue after embryogenesis (eg, alpha-fetoprotein [AFP]) or remain present on normal tissue but are overexpressed on cancer cells (eg, prostate-specific antigen [PSA]) In either case, the more ubiquitous nature of these antigens appears to cause reduced immune reactivity (also known as tolerance) Humoral Immunity A large number of monoclonal antibodies have been developed against a variety of tumor-associated antigens Oncofetal antigens such as AFP and beta-human chorionic gonadotropin (β-hCG) are important markers in germ cell tumors β-hCG is also expressed in a small percentage of patients with bladder carcinoma Antibodies directed against specific targets such as vascular endothelial growth factor (vegF) have been correctly developed and are being tested for the treatment of both advanced prostate cancer of RCC Antibodies in Cancer Diagnosis & Detection A PROSTATE CANCER Immunoassays are used to test both body fluids and tissues for the presence of tumor-associated antigens In the urologic cancers, the most obvious example is the development of monoclonal antibodies against PSA The utility and limitations of PSA are described elsewhere in this volume Other antigens that have been tested in prostate cancer include prostatic acid phosphatase, which has largely been replaced by PSA in screening programs and in patients with low tumor burden Prostatic acid phosphatase may be of some use in detecting or following up bone 297 Copyright © 2008, 2004, 2001, 2000 by The McGraw-Hill Companies, Inc Click

prostate-specific membrane antigen (PSMA) have been used, primarily for immunohistochemistry B RENAL CELL CARCINOMA Unfortunately, there are as yet no well-established antigens (or antibodies) that can be used to reliably evaluate and monitor renal cell carcinoma, although a variety of target antigens are being evaluated C BLADDER CANCER Two oncofetal antigens, β-hCG and carcinoembryonic antigen, are expressed by a minority (20% or less) of transitional cell carcinomas These markers are not routinely used, but in diagnostic dilemmas, measurement of serum levels of β-hCG or staining of tissue for this antigen may be useful D GERM CELL TUMORS As described in Chapter 23, antibodies to hCG and AFP are routinely used to detect shed antigen from germ cell tumors in the bloodstream These antigens can also be detected on tissue samples in the setting of some diagnostic dilemmas While the use of serum markers in germ cell tumors is reviewed elsewhere, it is worth noting that the presence of the oncofetoprotein AFP, either in serum or on tissue specimens, is pathognomic for a nonseminomatous germ cell tumor, regardless of results of routine pathologic evaluation In addition to their diagnostic utility, AFP and hCG can be used as markers of response to therapy and as predictive factors of outcome For example, the international germ cell tumor risk classification schema for patients with metastatic disease relies heavily on AFP and hCG levels as well as levels of a nonspecific marker, lactate dehydrogenase, to assign patients with nonseminomatous germ cell tumors to of risk levels (see Chapter 23) E RADIOIMMUNODETECTION Monoclonal antibodies to a specific antigen can be radiolabeled, and the preferential binding of the monoclonal antibody to tumor cells can be exploited Theoretically, such an approach could be used for the presurgical evaluation of disease, postsurgical evaluation for minimal residual disease, confirmation of cancer identified by other imaging modalities, and detection of recurrent disease There are several potential impediments to successful tumor radioimmunodetection These include dilution of antibody in the bloodstream; metabolism of the antibody; nonspecific binding in liver, reticuloendothelial system, bone marrow, and elsewhere; binding of antibody by circulating or shed antigen; and the development of neutralizing human antimouse antibodies The only radioimmunodetection system for urologic cancers at this time is 111 In-capromab pendetide (Prostascint), a murine monoclonal antibody to PSMA Its use has been hampered by a fairly laborious administration process, operator dependence in interpretation of scans, and a less than satisfactory positive predictive value The use of 111In-capromab pendetide is described in Chapter 10 Immunotherapy with Monoclonal Antibodies Immunotherapy with monoclonal antibodies alone (“naked antibodies”) has been fairly extensively evaluated The use of monoclonal antibodies against tumorassociated antigens has met with only limited success in patients with solid tumors In lymphoproliferative disorders such as leukemia and lymphoma, some antibodies to tumor-associated surface antigens appear to result in tumor cell death The mechanism for these effects is certainly multifactorial but may in part be mediated by resultant complement fixation Direct antiproliferative effects of antibodies on cancer cells can be achieved by antibodies against functionally important antigens Thus, the inhibition of growth factors and growth factor receptors and the activation or inhibition of signal transducing molecules are attractive therapeutic targets In the urologic cancers, while no approved monoclonal antibody therapy exists, trials of antibodies against growth factors, vascular endothelial growth factor (VEGF, an angiogenic molecule), and signal transduction molecules are being undertaken Kidney cancer is highly dependent on angiogenesis, and bevacizumab (an antibody agent against VEGF) has been shown to prolong time to progression in metastatic disease Results from a trial of interferon-alpha with and without bevacizumab are awaited There is, as well, an ongoing trial of chemotherapy with and without bevacizumab in patients with metastatic hormone refractory prostate cancer An alternative approach to naked antibodies is to conjugate any of a variety of cytotoxic agents to an antibody The advantage of this approach is a “bystander effect,” making it unnecessary to use an antibody that binds each and every cell This can be achieved in a variety of ways The most straightforward is to use the monoclonal antibody as a means of providing some targeting specificity for the cytotoxic agent used Cytotoxic agents used include radioisotopes, chemotherapy, and toxins such as ricin Other means of providing some specificity is to bind a prodrug (with an antibody) to the tumor site and then to activate the bound prodrug Finally, targeting with bispecific antibodies (eg, to antigen and to an effector T cell, or to antigen and toxin) has been undertaken These approaches have all been tested in prostate cancer, but all remain investigational at this point IMMUNOLOGY & IMMUNOTHERAPY OF UROLOGIC CANCERS / Cell-Mediated Immunity There is considerable evidence, both clinical and preclinical, that tumor-associated antigens can elicit a cellmediated immune response In some models, when carcinogen-induced tumors in mice are resected and the mouse is reinoculated with tumor cells, the tumor fails to regrow, suggesting the development of immunity to specific antigens Specific antigens that are rejected in immunized hosts are termed transplantation antigens The specificity of tumor rejection has since been demonstrated to reside in T lymphocytes (at a minimum) Lymphocytes of cancer patients can sometimes be stimulated in vitro to recognize specific tumor-associated antigens and consequently demonstrate properties of cytolytic T lymphocytes Unfortunately, the phenomenon of tumor rejection is by no means universal, either in the laboratory or clinically, and it is unusual to detect cytolytic-T-lymphocyte activity against many tumorassociated antigens Nevertheless, there are several clinical scenarios that suggest that cell-mediated antitumor responses exist These observations have promoted a broad search for the means of enhancing patients’ immune responses to tumor-associated antigens Renal cell carcinoma (RCC) is in many ways the prototypical immune-mediated tumor and, along with melanoma, has until recently been the primary target of immune manipulations A dramatic example of such an immune-mediated response is the phenomenon of spontaneous regression of metastatic RCC deposits after nephrectomy Classically this has been described in less than 1% of patients The impact of tumor debulking may also explain why a subset of RCC patients with lymph node or renal vein involvement that undergo resection are seemingly cured The exact mechanism of this phenomenon is not well understood but may involve elimination of inhibitors of cell-mediated immunity Indeed, tumor-infiltrating lymphocytes in RCC have been shown to exhibit mutant or faulty T-cell-receptor components, and it is not unreasonable to speculate that involvement in the tumor milieu in some fashion results in “deactivation” of such lymphocytes Immunotherapy Involving Cell-Mediated Immunity Additional evidence of cell-mediated immunity playing a role in tumor rejection lies in the results of a variety of immunotherapeutic interventions Immunotherapy can be broadly classified as active or passive This classification refers to the role the host’s immune system plays Thus, the passive transfer of preformed antibodies is contrasted to a vaccination program in which the host’s immune system must be capable of mounting an immune response Adoptive therapy refers to a middle ground in which efforts are made to reconstitute, modify, or bolster one of the effector cells involved ex vivo, followed by reinfusion 299 into the patient, where the rest of the immune cascade must then be recruited Active Immunotherapy: Vaccination Autologous vaccination programs (the vaccination of patients with their own tumor cells) have been extensively explored The advantage of autologous vaccination is that the vaccine bears the antigens of the patient’s tumor, although the distinct disadvantage is that not every patient has tumor available for vaccine preparation, and the preparation of each vaccine is tremendously labor intensive By contrast, allogeneic vaccines (the use of a generic vaccine or “off-the-shelf” antigen) have the benefit of mass production and ease of use, and the identification of specific tumor rejection antigens allows specific antigenic targeting However, this approach runs the risk of a more narrow shared antigenic spectrum with the patient’s tumor Both autologous and allogeneic vaccination strategies are under evaluation, both in RCC and prostate cancer Several means exist to undertake vaccination The simplest is to use intact but inactivated tumor cells Inactivation can be achieved with UV radiation, external beam (photon) radiation, or freeze-thawing Crude extracts of cells can also be used The advantage of using cell extracts is that inactivation is not necessary and small particles and proteins that might be more easily phagocytosed are available One can also enhance the immunogenicity of inoculated cells by growing the cells in cytokines, coinjecting with cytokines (nonspecific active immunotherapy, described below), or transfecting these cells with the genes for immune stimulatory cytokines or the costimulatory molecule B7 Current clinical trials are underway that use prostate cancer cell lines transfected with the GM-CSF gene (GVAX, Cell Genesys, South San Francisco, CA) for vaccination in patients with metastatic hormone refractory prostate cancer Purified protein or peptides represent a second potential vaccination schema In prostate cancer, trials of vaccination with PSMA and PSA are under way Trials of PSA in a vaccina and fowlpox (ProstaVax) are also underway A third way of undertaking specific vaccination is to attempt to bypass the antigen-presenting function of the immune system and to directly stimulate professional antigen-presenting cells, such as dendritic cells, ex vivo These cells can be stimulated by pulsing them with protein or peptides of interest or by transfecting them with a gene encoding the antigenic peptide of interest before re-infusion Initial trials of PAP-pulsed dendritic cells (Provenge, Dendreon Corporation, Seattle, WA) have demonstrated preliminary activity Confirmatory trials are ongoing Nonspecific Active Immunotherapy: Cytokines & Biologic Response Modifiers BCG (Bacillus Calmette-Guérin) is a live attenuated form of tubercle bacillus that appears to have local activity against 300 / CHAPTER 18 some tumors but has been largely disappointing as systemic therapy The utility of BCG in the treatment of superficial bladder cancer is well described and is beyond the scope of this chapter The mechanism by which BCG can elicit a local immune response in the uroepithelium and thereby exhibit impressive anticancer activity is not well delineated However, possible mechanisms of action include macrophage activation, lymphocyte activation, recruitment of dendritic cells, and natural killer cells It is intriguing that this is strictly a local phenomenon and that BCG has no role in the treatment of muscle-invasive or metastatic disease Interleukin-2 (IL-2) is a naturally occurring cytokine that has multiple immunoregulatory properties The observation that exogenously administered IL-2 could result in tumor regression in patients with RCC and melanoma was the first unequivocal indication that cancer regression could be mediated by immune manipulations IL-2 stimulates lymphocyte proliferation, enhances cytolytic-T-cell activity, induces natural killer cell activity, and induces gamma-interferon and tumor necrosis factor production IL-2 has no direct cytotoxicity, but when administered endogenously will activate effector cells of the host immune system, including lymphocytes, natural killer cells, lymphokine-activated killer cells, and tumor-infiltrating lymphocytes The details of immunotherapy for RCC are beyond the scope of this chapter Nevertheless, in brief, IL-2 has been administered in RCC in several different schemas, including highdose intravenous bolus (IL-2 is U.S Food and Drug Administration [FDA] approved with this schedule), continuous intravenous infusion, and at lower doses subcutaneously The high-dose regimens must be administered on an inpatient basis and are characterized by significant, albeit manageable, toxicities, including fever; malaise; vascular leak syndrome; hypotension; and cardiac, renal, and hepatic dysfunction Subcutaneous IL-2 is self-administered by patients in the outpatient setting, and while clearly less toxic, still has associated malaise and constitutional symptoms The optimal dosing regimen is not well established, and overall response proportions rarely exceed 20% Durable complete responses of 5–8% have been reported with some of the high-dose regimens IL-2 has also been combined with other active agents such as alpha-interferon and chemotherapy, although it is not clear if these combinations provide additional benefit Alpha-interferon is a naturally occurring cytokine that has direct cytotoxic and possibly antiproliferative properties, but also has immunoregulatory properties It enhances major histocompatibility complex expression, thereby potentially increasing the efficiency of antigen processing and recognition Alpha-interferon has anticancer activity in both RCC and superficial bladder cancer Its primary toxicity is fever, malaise, and constitutional symptoms, although at higher doses it can result in bone marrow toxicity, central nervous system toxicity, and hepatic toxicity In RCC, as a single agent, alpha-interferon can result in clinical responses in up to 20% of patients In contradistinction to IL-2 as a single agent, durable complete responses are quite rare Nevertheless, in randomized trials, alpha-interferon appears to confer a modest survival advantage over other agents now known to be largely inactive Alpha-interferon is also used as an intravesicle treatment in superficial bladder cancer, where it has established activity, and is not infrequently used as second-line therapy after BCG Granulocyte macrophage-colony stimulating factor (GM-CSF) is perhaps the most important cytokine in eliciting cellular immune responses Administered systemically as a subcutaneous injection, GM-CSF has been shown to reduce PSA in patients with both hormonesensitive and hormone-resistant prostate cancer However, the use of GM-CSF is neither proven to be of clinical benefit, nor approved for this indication, and must be considered investigational Immunomodulation A myriad of immunosuppressive factors exist within cancer patients that may serve to dampen anti-tumor immune responses Some of these molecules represent natural pathways to inhibit autoimmunity, while some molecules may have been usurped by the tumor to evade immune recognition Novel approaches are now being developed to target these pathways For example, CTLA-4 is an inhibitory molecule that blocks binding of B7 to CD28, thereby preventing costimulation and downmodulating T-cell activation By preventing the action of CTLA-4, an anti-CTLA-4 antibody (ipilimumab) can augment and prolong T-cell immune responses In animal models, ipilimumab antibody can induce tumor rejection in immunogenic tumors, and in combination with antitumor vaccination, can induce rejection of minimally immunogenic tumors, including in the transgenic adeno carcinoma of mouse/prostate (TRAMP) prostate cancer model In a phase I study, 14 patients with androgen insensitive prostate cancer were treated with a humanized anti-CTLA-4 antibody (MDX-010, Medarex, Inc., Bloomsbury, NJ) There was no evidence of polyclonal T-cell activation, therapy was well tolerated, and patients had ≥50% decline in their PSA The combination of CTLA-4 blockade with vaccination is of interest and is under investigation Adoptive Immunotherapy Adoptive immunotherapy is the transfer of cellular products (effector cells) to the host or patient in an effort to develop an immune response The use of adoptive immunotherapy was prompted by the observation that T cells derived from patients with melanoma or RCC had the ability to recognize antigens on the primary tumor Thus, it was hoped that these cells could be harvested, activated IMMUNOLOGY & IMMUNOTHERAPY OF UROLOGIC CANCERS / ex vivo, and then reinfused into patients Lymphokineactivated killer cells and tumor-infiltrating lymphocytes have been used to treat patients with metastatic RCC in the investigational setting, frequently along with IL-2 However, randomized trials comparing IL-2 alone with IL-2 plus cellular products have failed to demonstrate an improvement in response proportions or survival Chapter 22 gives specific details of immunotherapy in RCC REFERENCES Agarwala SS, Kirkwood JM:

The second feature to consider in treating patients with potentially curative systemic therapy is the anticipated toxicity of such therapy In general, higher levels of toxicity are acceptable if a cure can be achieved, although care must be exercised to avoid a “cure worse than the disease.” This is particularly true in the case of fairly toxic therapies such as interleukin-2 or bone marrow transplantation These treatments can result in apparent cures of approximately 10% and 30%, respectively, of patients with metastatic renal cell carcinoma or refractory germ cell tumors (GCT) Patients undergoing these rigorous therapies must be carefully selected and must be as fully informed as possible about potential toxicities Treatment of patients with incurable metastatic cancer—When the goal of systemic therapy is palliation of symptoms rather than cure, the toxicity of the treatment to be offered must be balanced against the cancer-related symptoms the patient is experiencing, and in general, more toxic therapies are not indicated Nonetheless, an understanding of the potential capabilities of systemic therapy must be understood because even in otherwise incurable disease there may be a role for systemic therapy if there is a likelihood that the patient’s life can be prolonged with its use In addition, systemic chemotherapy can be associated with a control of pain, and an improvement in quality of life This appears to be the case for both mitoxantrone and docetaxel in patients with metastatic hormone refractory prostate cancer Systemic therapy used in conjunction with surgery: adjuvant and neoadjuvant therapy—Systemic therapy administered after a patient has been rendered free of disease surgically is termed adjuvant therapy Several The use of chemotherapy in the treatment of malignant tumors of the genitourinary system serves as a paradigm for a multidisciplinary approach to cancer The careful integration of surgical and chemotherapeutic treatments has resulted in impressive advances in the management of urologic cancer By definition, surgical interventions are directed at local management of urologic tumors, whereas chemotherapy and biologic therapy are systemic in nature While there is no question that there are times in the natural history of genitourinary tumor when only one therapeutic method is required, a multidisciplinary approach is always called for This chapter details the importance of a joint surgical-medical approach to patients with urologic cancer A practicing urologist should collaborate closely with a medical oncologist and should feel comfortable speaking with patients about the uses, risks, and benefits of chemotherapy PRINCIPLES OF SYSTEMIC THERAPY A CLINICAL USES OF CHEMOTHERAPY Systemic therapy is indicated in the treatment of disseminated cancer when either cure or palliation is the goal Additionally, chemotherapy may be used as part of a multimodality treatment plan in an effort to improve both local and distant control of the tumor An understanding of the goals and limitations of systemic therapy in each of these settings is essential to its effective use Curative intent of metastatic disease—In considering the role of potentially curative chemotherapy in patients with metastatic disease, several factors must be taken into account The first is the responsiveness of the tumor Responsiveness is generally defined by the observed partial, complete, and overall responses It is important to note that a complete response implies complete resolution of abnormal serum tumor markers, if any, and complete radiographic resolution of any abnormalities This makes the assessment of neoplasms with frequent bony metastases such as prostate cancer, renal cell carcinoma, and transitional cell carcinoma difficult, as a persistently abnormal bone scan does not necessarily imply residual cancer Patients in whom the only site of disease is bone generally must be considered non-assessable by conventional measures, and if available, intermediate markers of response (such as prostate-specific antigen [PSA]) are required 302 Copyright © 2008, 2004, 2001, 2000 by The McGraw-Hill Companies, Inc Click here for terms of use CHEMOTHERAPY OF UROLOGIC TUMORS / important criteria must be met if adjuvant therapy is to be used outside of a research setting First, an assessment must be undertaken of known risk factors predictive of relapse or development of distant metastases Patients at low risk of relapse generally should not receive adjuvant therapy because they are unlikely to derive a benefit and will be unnecessarily exposed to the toxicity of therapy Second, the proposed therapy must have been shown to decrease the rate of relapse and increase the disease-free interval (and, it is hoped, survival) in a randomized, phase III trial Finally, because patients who are being treated with adjuvant therapy are free of disease and presumably asymptomatic, toxicity must be kept at a minimum This opens the way to a tailored approach in which patients with high-risk disease, as determined by pathologic review of the surgical specimen, are treated in order to decrease the risk of micrometastatic disease By contrast, neoadjuvant therapy is administered before definitive surgical resection Here, the potential advantages include early therapy of micrometastatic disease and tumor debulking to allow a more complete resection Patients with known metastatic disease generally not exhibit high enough response rates to systemic therapy to warrant local surgery following chemotherapy, with the clear exception of patients with GCT Whether or not patients with metastatic renal cell carcinoma who exhibit a partial response to systemic therapy may benefit from resection of residual masses is not known As with adjuvant therapy, 303 the proposed therapy must have been demonstrated to impact favorably on rate of relapse, disease-free interval, and survival in a randomized phase III trial B CHEMOTHERAPEUTIC AGENTS AND THEIR TOXICITY The usefulness of antineoplastic agents lies in their therapeutic index or preferential toxicity to malignant cells over normal, nonmalignant cells The mechanism of action of most chemotherapeutic drugs is based on their toxicity to rapidly dividing cells Thus, in general, malignancies that have relatively rapid growth, such as GCT, are relatively chemosensitive, whereas slower growing neoplasms such as renal cell carcinoma are less sensitive Toxicity from chemotherapeutic agents is seen primarily in normal, nonmalignant cells that are also rapidly dividing, such as hematopoietic cells in the bone marrow, gastrointestinal mucosa, and hair follicles, and is manifested in cytopenias, mucositis, and alopecia Other common toxicities observed with agents frequently used in the treatment of genitourinary malignancies include nephrotoxicity, neurotoxicity, hemorrhagic cystitis, pulmonary fibrosis, and cardiotoxicity Table 19–1 summarizes the spectrum of activity and primary toxicities of commonly used chemotherapeutic agents The development of chemotherapy drug resistance remains an important clinical problem in the field of oncology Malignant cells develop resistance in a variety of ways, including the induction of transport pumps, which Table 19–1 Commonly Used

actively pump the drug out of the cell and through increased activity of enzymes necessary to inactivate the particular chemotherapeutic agent While there are several experimental methods of circumventing these mechanisms of drug resistance, one practical approach to this problem is the use of multiagent chemotherapy Increased tumor cell killing is achieved by exposing neoplastic cells to multiple agents with different mechanisms of action Furthermore, this approach allows the selection of agents with nonoverlapping toxicity profiles The use of increased dose intensity (higher doses of a drug administered over the same time period) as a means of overcoming drug resistance remains experimental in urologic malignancies with one clear exception A subset of patients with otherwise incurable GCT appear to be curable with high-dose chemotherapy and autologous bone marrow transplant support (see the section Germ Cell Malignancies, following) C UNIQUE FEATURES OF GENITOURINARY MALIGNANCIES The systemic therapy of urologic malignancies offers unique challenges to the practitioner Renal insufficiency due to obstructive uropathy from local extension of the tumor or postsurgical or postradiotherapy changes is not infrequent and may alter antineoplastic drug clearance In patients with renal cell carcinoma, previous nephrectomy also may impact on drug clearance Furthermore, the common use of the nephrotoxic chemotherapeutic agent cisplatin in the treatment of urologic malignancies (most prominently, in bladder and testicular neoplasms) may further diminish renal function Careful attention must be paid, therefore, to renal function throughout the course of systemic therapy, with appropriate dose adjustments made Dosing adjustments also must be considered in patients who have undergone cystectomy because ileal conduits or neobladders have the capacity to resorb chemotherapeutic agents that are excreted in the urine in active form (most notably, methotrexate) Frequent local extension in the pelvis presents additional unique problems Patients with previous pelvic radiotherapy have markedly diminished bone marrow reserves, which may limit the use of myelosuppressive drugs Furthermore, local pelvic relapses have the potential to be symptomatic and painful Particularly in patients who have already received radiotherapy, systemic therapy may be important for palliation GERM CELL MALIGNANCIES A OVERVIEW The evolution of therapy for GCT has been deliberate and thoughtful, and has resulted in cures of 80–85% of men with GCT, serving as a model for the treatment of curable cancers Nonetheless, challenges in the management of GCT remain Because of their young age, patients who have been cured are at risk of delayed, treatment-induced toxicity Furthermore, an 80–85% cure rate also implies that 15–20% of patients with GCT will not be cured and ultimately will succumb to their disease An understanding of staging and risk assessment is crucial if (1) patients with good risk features are not to be overtreated and exposed to undue toxic risks, and (2) patients with poor risk features are to receive adequate (curative) therapy The most common multiagent chemotherapy regimen for the treatment of GCT is a 3-drug combination consisting of bleomycin, etoposide, and cisplatin (BEP) The treatment is repeated every 21 days One cycle consists of cisplatin 20 mg/m2 IV day 1–5, etoposide 100 mg/m2 IV day 1–5, and bleomycin, 30 units IV, day 2, 9, and 16 Frequently the first days of treatment require hospitalization The deletion of bleomycin from this regimen results in the PE regimen The substitution of ifosfamide for bleomycin yield the VIP regime (UP-16, ifosfamide, platinum) B USE OF CHEMOTHERAPY FOR PATIENTS WITH STAGE I AND II DISEASE The standard of care for patients with stage I GCT remains orchiectomy followed by retroperitoneal lymphadenectomy (nonseminoma), radiation therapy (seminoma), or in selected patients, careful surveillance The use of chemotherapy in stage I GCT in lieu of lymphadenectomy or irradiation remains investigational despite encouraging early results Patients with stage II nonseminomatous microscopic disease identified at lymphadenectomy (stage IIA) or patients with low-volume clinical stage II disease (stage IIB) who have undergone retroperitoneal lymphadenectomy may benefit from cycles of adjuvant PE or PEB chemotherapy The use of adjuvant therapy results in a 96% long-term disease-free survival While the relapse rate for patients who not receive adjuvant therapy approaches 40%, the vast majority of relapsing patients can also be cured with either or cycles of chemotherapy, yielding an identical long-term survival rate The decision about adjuvant chemotherapy after lymphadenectomy must be individualized Patients at high risk for relapse may choose to undergo cycles of chemotherapy at that point in order to avoid the possibility of 3–4 cycles in the future C USE OF CHEMOTHERAPY IN PATIENTS WITH ADVANCED DISEASE Patients with advanced GCT should be treated with systemic therapy after completion of their orchiectomy This group includes some stage IIB nonseminomatous tumors and all stage IIC or higher tumors, both seminomas and nonseminomas A variety of chemotherapy regimens will result in approximately 80% of patients with advanced GCT achieving a complete response and 70% achieving CHEMOTHERAPY OF UROLOGIC TUMORS / long-term apparent cures (good prognosis) By the same token, however, 20–30% of patients have a poor prognosis and will still ultimately die from their disease Studies of pretreatment clinical characteristics have sought to identify prognostic features that can be prospectively used to segregate this diverse group of advanced GCT patients into poor- and good-prognostic subsets A common classification system has been developed by the International Germ Cell Cancer Collaborative Group (IGCCC) In this system, good-prognosis patients with nonseminomatous GCT have a testis or retroperitoneal primary tumor, no nonpulmonary visceral metastases, and low-serum tumor markers Intermediate-prognosis patients are the same as good-prognosis patients but have intermediate serum tumor markers Poor-prognosis patients have a mediastinal primary tumor or nonpulmonary visceral metastases (liver, bone, brain) or high levels of serum tumor markers Five-year overall survival for the good-, intermediate-, and poor-prognosis categories with current regimens is 92%, 80%, and 48%, respectively By definition, seminomas are never in the poor-prognosis category Seminomas are segregated into good-prognosis cases (any primary site, but no nonpulmonary visceral metastases), with an 86% 5year survival, and intermediate-prognosis cases (any primary site but with the presence of nonpulmonary visceral metastases), with a 72% 5-year survival Because it is not likely that the extraordinarily high cure rate for good-prognosis patients can be improved upon, most efforts in the treatment of these patients have been aimed at optimizing treatment with less toxic regimens that will have equal efficacy Trials evaluating (1) the elimination of bleomycin, (2) a reduction in the number of chemotherapy cycles administered, or (3) the substitution of carboplatin for cisplatin have been undertaken The outlook for poor-prognosis patients is grim, with only 38–62% of patients achieving a complete response Thus, whereas the major concern in goodprognosis patients has been the reduction of toxicity, the major objective of clinical investigation in poor-prognosis patients has been to improve efficacy, with less concern for reducing toxicity Clinical trials in poor-prognosis patients have by and large relied on one or both of two approaches The first has been to exploit agents that have been demonstrated to be efficacious in the salvage setting, and the second has been to evaluate the role of dose escalation Currently acceptable regimens for good-prognosis patients are fairly well defined and include cycles of PEB or cycles of PE By contrast, optimal therapy for poorprognosis patients continues to be investigational Four cycles of PEB or cycles of VIP (are appropriate options D ADJUNCTIVE SURGERY AND “SALVAGE” THERAPY Postchemotherapy adjunctive surgery must be integrated into the treatment plan of patients with advanced GCT Between 10% and 20% of patients with nonseminoma- 305 tous tumors have residual masses after systemic therapy, and up to 80% of patients with seminomas have residual radiographic abnormalities The role of adjunctive surgery in patients with GCT with postchemotherapy residual masses has been reviewed Except in rare circumstances, adjunctive surgery is not indicated in the presence of persistently elevated serum tumor markers Adjunctive surgery usually can be undertaken safely within 1–2 months of completion of chemotherapy It must be noted, however, that all patients who have received bleomycin, whether or not there is clinical evidence of pulmonary fibrosis, are at risk of development of oxygen-related pulmonary toxicity The anesthesiologist must be made aware of the patient’s previous exposure to bleomycin and every effort must be taken to maintain the FiO2 as low as possible throughout the surgical procedure Patients who are found to have active carcinoma in their resected specimens are frequently treated with further “salvage” chemotherapy, generally with a different regimen, although compelling evidence supporting this procedure is still forthcoming Patients who appear to benefit from postsurgical chemotherapy are patients with incomplete resections, patients whose resected specimen contains more than 10% viable cancer cells, and patients who were in the IGCCC high-risk group prior to beginning frontline chemotherapy While approximately 80% of patients with GCT can currently be cured with platinum-based therapy, 20% ultimately die of their disease, either because a complete response is not achieved with induction therapy or because they relapse after becoming disease-free with primary therapy Before the initiation of salvage therapy, the diagnosis of relapsed or primary, refractory GCT must be clearly established In particular, falsely elevated human chorionic gonadotropin or alpha-fetoprotein values and false-positive radiographic studies of the chest due to previous bleomycin use must be ruled out Persistent or slowly growing masses, particularly in the absence of serologic progression, may represent benign teratoma Therapies based on ifosfamide, paclitaxel, or high-dose chemotherapy with autologous bone marrow transplant provide a salvage rate of approximately 25% in patients with relapsed or refractory GCT TRANSITIONAL CELL CARCINOMA OF THE UROEPITHELIUM A NONMETASTATIC DISEASE The development of effective chemotherapy regimens for the treatment of metastatic transitional cell carcinoma (TCC) has resulted in more widespread use of these regimens in combination with other modes for the treatment of locally advanced but nonmetastatic disease In bulky inoperable invasive bladder tumors (T3b, T4, N+), chemotherapy has been used as a means of cytoreduction in order to make surgery possible Chemotherapy before sur- 306 / CHAPTER 19 gery, termed neoadjuvant therapy, has also been used in muscle-invasive cancers that are resectable, in an effort to treat micrometastatic disease before cystectomy It must be borne in mind that the pathologic complete response rate in the bladder after neoadjuvant chemotherapy is probably in the 30–40% range; therefore, definitive surgical resection after chemotherapy is usually required A modest survival advantage has been demonstrated with neoadjuvant MVAC chemotherapy (see below) Other investigators believe that adjuvant therapy administered after radical cystectomy should be the means of treating patients with invasive bladder cancer at risk for relapse Adjuvant trials generally have been used to treat only patients found to have pathologic T3 and T4 lesions Several small randomized trials have shown a benefit to various adjuvant chemotherapy regimens; a large randomized multi-institution trial remains to be done Chemotherapy in combination with radiation therapy has been advocated by some as a bladder-preserving approach for muscle-invasive tumors Patients are usually treated with cycles of chemotherapy, followed by radiation therapy and concomitant cisplatin as a radiosensitizer If follow-up cystoscopy reveals no cancer, consolidative multiagent systemic chemotherapy is administered This approach appears to be particularly useful for smaller, lower-stage tumors The presence of hydronephrosis or hydroureter is a contradiction to this approach, as these patients less well with a bladder sparing approach While longer follow-up is required, it appears that approximately 30–50% of patients can attain long-term diseasefree status with a functional bladder with this approach B METASTATIC DISEASE The development of successful therapy of metastatic bladder TCC has been based on the use of cisplatin Until recently, two common cisplatin-based regimens are in wide use: (1) cisplatin, methotrexate, and vinblastine (CMV) and (2) the same drugs in a slightly different schedule and dose along with doxorubicin (Adriamycin), in a regimen known as MVAC These regimens result in overall response rates of approximately 50–60% and complete remission rates in the 20–35% range Median overall survival for patients with metastatic disease treated with these regimens is in the 8- to 14-month range Despite early promise, however, long-term survival after MVAC or CMV remains in the single digits Both CMV and MVAC are intensive regimens, with myelosuppression occurring commonly The use of hematopoietic growth factors has made it easier to administer full doses on schedule, although this improvement in dose intensity does not appear to translate into a clinical benefit More recently, the combination of gemcitabine and cisplatin has been compared to MVAC This new regimen is far less toxic, is better tolerated, and appears to be equivalent in efficacy to MVAC As a consequence, gemcitabine/ cisplatin can be considered the new standard of care for the treatment of advanced TCC However, it should be noted that the gemcitabine/cisplatin regime has been tested in a randomized study only in patients with metastatic disease, and its utility as an adjuvant or neoadjuvant has not been tested For patients with impaired renal function, agents such as carboplatin and paclitaxel have been utilized RENAL CELL CARCINOMA The treatment of metastatic renal cell carcinoma with chemotherapy remains largely unsatisfactory The general lack of active agents and the excessive toxicity of many of the agents that exhibit some activity have contributed to the absence of adjuvant or neoadjuvant trials The only such trials used adjuvant interferon-alpha for patients considered at high risk for relapse after nephrectomy and failed to show an advantage of the adjuvant therapy Nephrectomy prior to systemic therapy is recommended, particularly in patients in whom the bulk of disease is in the renal mass, and who have a good performance status Metastatic renal cell carcinoma is relatively resistant to chemotherapy The fluoropyrimidines floxuridine, 5fluorouracil, and capecitabine have modest activity, as does gemcitabine, with response proportions of 10–15% reported Renal cell carcinoma is one of very few neoplasms that clearly are responsive to biologic response modifiers The utility of biologic response modifiers and anti-angiogenic agents in renal cell carcinoma is discussed elsewhere in Chapter 20 In general, these agents are used prior to using chemotherapy HORMONE-REFRACTORY PROSTATE CANCER The systemic therapy of patients with metastatic prostate cancer in whom hormonal therapy has failed generally consists of secondary hormonal manipulations followed by chemotherapy Approximately 15% of patients who have had progressive disease despite therapy with combined androgen blockade will have a fall in PSA when their antiandrogen is discontinued This maneuver is mandated, therefore, before initiating other systemic therapy Furthermore, second-line hormonal maneuvers such as adrenal androgen deprivation with ketoconazole, estrogens, or secondary antiandrogens such as nilutamide clearly have activity and, particularly in asymptomatic patients, should be considered As noted previously, the evaluation of responses in patients with bone disease only is difficult at best The use of the PSA in this setting has been fairly extensively evaluated, and it appears to be a reasonable intermediate endpoint Thus, a decline in PSA of 35–50% appears to be predictive of longer survival for these patients Several agents or combinations of agents show promise in the therapy of HRPC Not only can a significant 742 / INDEX Intersex disorders (cont.) mixed, 657t, 672–673, 673f pure, 658t, 672 XY, 673f male
