Purpose To compare long-term survival in patients with locally advanced or metastatic transitional cell carcinoma (TCC) of the urothelium treated with gemcitabine/cisplatin (GC) or methotrexate/vinblastine/doxorubicin/cisplatin (MVAC). Patients and Methods Efficacy data from a large randomized phase III study of GC versus MVAC were updated. Time-to-event analyses were performed on the observed distributions of overall and progression-free survival. Results A total of 405 patients were randomly assigned: 203 to the GC arm and 202 to the MVAC arm. At the time of analysis, 347 patients had died (GC arm, 176 patients; MVAC arm, 171 patients). Overall survival was similar in both arms (hazard ratio [HR], 1.09; 95% CI, 0.88 to 1.34; P = .66) with a median survival of 14.0 months for GC and 15.2 months for MVAC. The 5-year overall survival rates were 13.0% and 15.3%, respectively (P = .53). The median progression-free survival was 7.7 months for GC and 8.3 months for MVAC, with an HR of 1.09. The 5-year progress...

OBJECTIVES The first consensus report presented by the European Germ Cell Cancer Consensus Group (EGCCCG) in the year 2004 has found widespread approval by many colleagues throughout the world. In November 2006, the group met a second time under the auspices of the Department of Urology of the Amsterdam Medical Center, Amsterdam, The Netherlands. METHODS Medical oncologists, urological surgeons, radiation oncologists as well as pathologists from several European countries reviewed and discussed the data that had emerged since the 2002 conference, and incorporated the new data into updated and revised guidelines. As for the first meeting, the methodology of evidence-based medicine (EBM) was applied. The results of the discussion were compiled by the writing committee. All participants have agreed to this final update. RESULTS The first part of the consensus paper describes the clinical presentation of the primary tumor, its treatment, the importance and treatment of testicular intraepithelial neoplasia (TIN), histological classification, staging and prognostic factors, and treatment of stage I seminoma and non-seminoma. CONCLUSIONS Whereas the vast majority of the recommendations made in 2004 remain valid 3 yr later, refinements in the treatment of early- and advanced-stage testicular cancer have emerged from clinical trials. Despite technical improvements, expert clinical skills will continue to be one of the major determinants for the prognosis of patients with germ cell cancer. In addition, the particular needs of testicular cancer survivors have been acknowledged.

PURPOSE: Several management options are available to patients with stage I seminoma, including adjuvant radiotherapy, surveillance, and adjuvant chemotherapy. We performed a pooled analysis of patients from the four largest surveillance studies to better delineate prognostic factors associated with disease progression. PATIENTS AND METHODS: Individual patient data were obtained from each center (Princess Margaret Hospital, Danish Testicular Cancer Study Group, Royal Marsden Hospital, and Royal London Hospital) for 638 patients. Tumor characteristics (size, histologic subtype, invasion of rete testis, and tumor invasion into small vessels [SVI]) as well as age at diagnosis were analyzed for prognostic importance for relapse. RESULTS: With a median follow-up of 7.0 years (range, 0.02 to 17.5 years), 121 relapses were observed for an actuarial 5-year relapse-free rate (RFR) of 82.3%. On univariate analysis, tumor size (RFR: ≤ 4 cm, 87%; > 4 cm, 76%; P = .003), rete testis invasion (RFR: 86% [absent] v 77% [p...

PURPOSE Vinflunine (VFL) is a new microtubule inhibitor that has activity against transitional cell carcinoma of urothelial tract (TCCU). We conducted a randomized phase III study of VFL and best supportive care (BSC) versus BSC alone in the treatment of patients with advanced TCCU who had experienced progression after a first-line platinum-containing regimen. PATIENTS AND METHODS The study was designed to compare overall survival (OS) between patients receiving VFL + BSC (performance status [PS] = 0: 320 mg/m(2), every 3 weeks; PS = 0 with previous pelvic radiation and PS = 1: 280 mg/m(2) subsequently escalated to 320 mg/m(2)) or BSC. RESULTS Three hundred seventy patients were randomly assigned (VFL + BSC, n =253; BSC, n = 117). Both arms were well balanced except there were more patients with PS more than 1 (10% difference) in the BSC arm. Main grade 3 or 4 toxicities for VFL + BSC were neutropenia (50%), febrile neutropenia (6%), anemia (19%), fatigue (19%), and constipation (16%). In the intent-to-treat population, the objective of a median 2-month survival advantage (6.9 months for VFL + BSC v 4.6 months for BSC) was achieved (hazard ratio [HR] = 0.88; 95% CI, 0.69 to 1.12) but was not statistically significant (P = .287). Multivariate Cox analysis adjusting for prognostic factors showed statistically significant effect of VFL on OS (P = .036), reducing the death risk by 23% (HR = 0.77; 95% CI, 0.61 to 0.98). In the eligible population (n = 357), the median OS was significantly longer for VFL + BSC than BSC (6.9 v 4.3 months, respectively), with the difference being statistically significant (P = .040). Overall response rate, disease control, and progression-free survival were all statistically significant favoring VFL + BSC (P = .006, P = .002, and P = .001, respectively). CONCLUSION VFL demonstrates a survival advantage in second-line treatment for advanced TCCU. Consistency of results exists with significant and meaningful benefit over all efficacy parameters. Safety profile is acceptable, and therefore, VFL seems to be a reasonable option for TCCU progressing after first-line platinum-based therapy.

PURPOSE The combination of gemcitabine plus cisplatin (GC) is a standard regimen in patients with locally advanced or metastatic urothelial cancer. A phase I/II study suggested that a three-drug regimen that included paclitaxel had greater antitumor activity and might improve survival. PATIENTS AND METHODS We conducted a randomized phase III study to compare paclitaxel/cisplatin/gemcitabine (PCG) with GC in patients with locally advanced or metastatic urothelial carcinoma. Primary outcome was overall survival (OS). Secondary outcomes were progression-free survival (PFS), overall response rate, and toxicity. RESULTS From 2001 to 2004, 626 patients were randomly assigned; 312 patients were assigned to PCG, and 314 patients were assigned to GC. After a median follow-up of 4.6 years, the median OS was 15.8 months on PCG versus 12.7 months on GC (hazard ratio [HR], 0.85; P = .075). OS in the subgroup of all eligible patients was significantly longer on PCG (3.2 months; HR, 0.82; P = .03), as was the case in patients with bladder primary tumors. PFS was not significantly longer on PCG (HR, 0.87; P = .11). Overall response rate was 55.5% on PCG and 43.6% on GC (P = .0031). Both treatments were well tolerated, with more thrombocytopenia and bleeding on GC than PCG (11.4% v 6.8%, respectively; P = .05) and more febrile neutropenia on PCG than GC (13.2% v 4.3%, respectively; P < .001). CONCLUSION The addition of paclitaxel to GC provides a higher response rate and a 3.1-month survival benefit that did not reach statistical significance. Novel approaches will be required to obtain major improvements in survival of incurable urothelial cancer.

PURPOSE We have previously demonstrated a significant negative impact of intratumoral neutrophils in metastatic renal cell carcinoma. This study assessed intratumoral neutrophils in localized clear cell renal cell carcinoma (RCC). PATIENTS AND METHODS The study comprised 121 consecutive patients who had a nephrectomy for localized RCC. Biomarkers (intratumoral CD8+, CD57+ immune cells, CD66b+ neutrophils, and carbonic anhydrase IX [CA IX]) were assessed by immunohistochemistry, and the relationship with clinical and histopathologic features and patient outcome was evaluated. RESULTS The intratumoral neutrophils ranged from zero to 289 cells/mm(2) tumor tissue. The presence of intratumoral neutrophils was statistically significantly associated with increasing tumor size, low hemoglobin, high creatinine, and CA IX < or = 85%. In multivariate analysis, the presence of intratumoral neutrophils (hazard ratio [HR], 3.0; 95% CI, 1.7 to 5.4; P < .0001), pT stage T3b/T4 (HR, 2.1; 95% CI, 1.2 to 3.6; P = .007), and low hemoglobin (HR, 1.8; 95% CI, 1.0 to 3.1; P = .03) were independent prognostic factors significantly associated with short recurrence-free survival. The presence of intratumoral neutrophils was also an independent prognostic factor for cancer-specific survival (HR, 3.5; 95% CI, 1.9 to 6.4; P < .0001) and overall survival (HR, 3.1; 95% CI, 1.9 to 5.0; P < .0001). Applying the prognostic value of intratumoral neutrophils to the Leibovich low-/intermediate-risk group (n = 78) showed a 5-year recurrence-free survival of 53% (95% CI, 34.6% to 71.8%; presence of intratumoral neutrophils) versus 87% (95% CI, 77.8% to 96.8%; absence of intratumoral neutrophils). The estimated concordance index was 0.74 using the Leibovich risk score and 0.80 when intratumoral neutrophils were added. CONCLUSION The presence of intratumoral neutrophils is a new, strong, independent prognostic factor for short recurrence-free, cancer-specific, and overall survival in localized clear cell RCC.

PURPOSE The present study sought to identify pretreatment prognostic factors for overall survival (OS) in patients with metastatic transitional cell carcinoma of the urothelial tract (TCCU) who experienced treatment failure with the first-line, platinum-based regimen included in the phase III vinflunine trial. PATIENTS AND METHODS In total, 370 patients with platinum-refractory TCCU were included in this analysis. Potential prognostic factors were recorded prospectively. Univariate analysis was used to identify clinical and laboratory factors that significantly impact survival. Multivariate analysis was used to identify independent prognostic factors, and bootstrap analysis was performed for internal validation, forming a prognostic model. External validation was performed on the phase II vinflunine study CA183001. RESULTS Multivariate analysis and the internal validation identified Eastern Cooperative Oncology Group performance status (PS) more than 0, hemoglobin level less than 10 g/dL, and the presence of liver metastasis as the main adverse prognostic factors for OS. External validation confirmed these prognostic factors. Four subgroups were formed based on the presence of zero, one, two, or three prognostic factors; the median OS times for these groups were 14.2, 7.3, 3.8, and 1.7 months (P < .001), respectively. CONCLUSION We identified and both internally and externally validated three adverse risk factors (PS, hemoglobin level, and liver metastasis) that predict for OS and developed a scoring system that classifies patients with platinum-refractory disease on second-line chemotherapy into four risk groups with different outcome. Similar to the first-line setting, the presence of visceral metastases and poor PS predict a worse prognosis. These factors, together with low hemoglobin, can be used for prognostication and future patient stratification in clinical trials.

Frede Donskov; Hans von der Maase

PURPOSE The purpose of this study was to evaluate the impact of immunologic prognostic factors in combination with established clinical prognostic factors in patients with metastatic renal cell carcinoma (mRCC). PATIENTS AND METHODS A total of 120 consecutive patients with mRCC received interleukin-2 (IL-2) -based immunotherapy. Baseline tumor biopsies were available from 85 of these patients. Potential prognostic factors were analyzed by univariate and multivariate analyses. RESULTS Multivariate analysis (N = 120) identified high lactate dehydrogenase, lymph node metastases, low hemoglobin, low Karnofsky performance status, and bone metastases as independent poor prognostic clinical factors. The impact of these clinical factors has been demonstrated by others. Multivariate analysis (n = 85) also identified a high blood neutrophil count (> 6.0 x 10(9)/L; hazard ratio, 2.0; P = .015), the presence of intratumoral neutrophils (> 0 cells/mm2 tumor tissue; hazard ratio, 2.3; P = .001), and low intratumoral CD57+ natural killer cell count (< 50 cells/mm2 tumor tissue; hazard ratio, 2.1; P = .01) as independent poor prognostic immunologic factors. These three independent immunologic parameters had significant discriminatory power as supplemental risk factors in prognostic models based on the clinical risk factors, identifying subgroups within the favorable clinical group with estimated 5-year survival rates of 60%, 25%, and 0%, respectively. These findings were apparent in both our own prognostic model and in an extended Memorial Sloan-Kettering Cancer Center (New York, NY) prognostic model. CONCLUSION This study points on five clinical and three supplemental immunologic independent prognostic factors of survival in patients with mRCC receiving IL-2.

Purpose: Cisplatin-containing chemotherapy is the standard of care for patients with locally advanced and metastatic transitional cell carcinoma of the urothelium. The response rate is ∼50% and tumor-derived molecular prognostic markers are desirable for improved estimation of response and survival. Experimental Design: Affymetrix GeneChip expression profiling was carried out using tumor material from 30 patients. A set of genes with an expression highly correlated to survival time after chemotherapy was identified. Two genes were selected for validation by immunohistochemistry in an independent material of 124 patients receiving cisplatin-containing therapy. Results: Fifty-five differentially expressed genes correlated significantly to survival time. Two of the protein products (emmprin and survivin) were validated using immunohistochemistry. Multivariate analysis identified emmprin expression (hazard ratio, 2.23; P < 0.0001) and survivin expression (hazard ratio, 2.46; P < 0.0001) as independent prognostic markers for poor outcome, together with the presence of visceral metastases (hazard ratio, 2.62; P < 0.0001). In the clinical good prognostic group of patients without visceral metastases, both markers showed significant discriminating power as supplemental risk factors (P < 0.0001). Within this group of patients, the subgroups of patients with no positive, one positive, or two positive immunohistochemistry scores (emmprin and survivin) had estimated 5-year survival rates of 44.0%, 21.1%, and 0%, respectively. Response to chemotherapy could also be predicted with an odds ratio of 4.41 (95% confidence interval, 1.91-10.1) and 2.48 (95% confidence interval, 1.1-5.5) for emmprin and survivin, respectively. Conclusions: Emmprin and survivin proteins were identified as strong independent prognostic factors for response and survival after cisplatin-containing chemotherapy in patients with advanced bladder cancer.

PURPOSE An elevated count of blood neutrophils and monocytes recently was shown independently to predict short survival in patients with stage IV melanoma undergoing interleukin-2-based immunotherapy. In this study, we aimed to validate this finding in a large cohort of stage IV melanoma patients. PATIENTS AND METHODS For this retrospective prognostic study, the data from the European Organisation for the Research and Treatment of Cancer 18951 study were used. Patients were randomly assigned between treatment with dacarbazine, cisplatin, and interferon alfa with or without interleukin-2. Counts of neutrophils and leukocytes were analyzed together with other known prognostic factors: serum lactate dehydrogenase, performance status, metastatic site, and sex. Two multivariate prognostic factor analyses were carried out in the model: one with leukocyte counts and one with neutrophil counts. RESULTS A total of 363 patients were randomly assigned and baseline blood neutrophil and leukocyte counts were available from 316 and 350 patients, respectively. A high neutrophil count (> 7.5 x 10(9)/L) was an independent prognostic factor for short overall survival (hazard ratio [HR], 1.5; 95% CI, 1.1 to 2.1; P = 0.02), and a high leukocyte count (> 10 x 10(9)/L) was an independent prognostic factor of both short overall survival (HR, 1.7; 95% CI, 1.3 to 2.4; P = 0.0005) and short progression-free survival (HR, 1.5; 95% CI, 1.1 to 2.1; P = 0.008). CONCLUSION A high pretreatment count of neutrophils in blood was confirmed as an independent prognostic factor for short overall survival in stage IV melanoma patients undergoing interleukin-2-based immunotherapy. Furthermore, a high count of leukocytes was an independent prognostic factor for short overall survival and progression-free survival. Both parameters should be useful as stratification factors in clinical trials.
