Second-line Chemotherapy in Older Patients With Metastatic Urothelial Carcinoma: Pooled Analysis of 10 Second-line Studies. Clin Genitourin Cancer 2017; 15:e563-e571. [PMID: 28065418 DOI: 10.1016/j.clgc.2016.12.014] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2016] [Revised: 12/05/2016] [Accepted: 12/10/2016] [Indexed: 11/18/2022]
Abstract
BACKGROUND Older patients with metastatic urothelial carcinoma (UC) are under-represented in clinical trials, and data regarding outcomes for second-line therapy is limited. MATERIALS AND METHODS Individual data for patients with metastatic UC, aged ≥ 70 years, were pooled from 10 second-line studies. The influence of potential prognostic factors on overall survival (OS) was assessed via univariate and multivariate Cox regression analysis. RESULTS In total, 102 patients were included; the median age was 74.0 years (range, 70-88 years). Second-line chemotherapy was single-agent in 42 (41%) patients and combination regimens in 60 (59%) patients. Median progression-free and OS were 4.3 and 9.7 months, respectively. In multivariate analysis, age > 75 years, Eastern Cooperative Oncology Group performance status ≥ 1, serum hemoglobin < 10 g/dL, and non-lymph node only metastasis predicted inferior OS. Median OS for patients with 0, 1, 2, and ≥ 3 adverse factors was unreached, 15.5, 9.8, and 4.8 months, respectively (P < .001). There was no difference in OS between patients treated with single-agent or combination chemotherapy. Combination regimens were associated with higher occurrences of any ≥ grade 2 toxicity (80% vs. 38%; P < .001), ≥ grade 2 hematologic (78% vs. 12%; P < .001), and ≥ grade 2 gastrointestinal toxicity (36% vs. 7%; P < .001). CONCLUSION In this pooled analysis of older patients with metastatic UC, combination chemotherapy for second-line treatment was associated with greater toxicity without improvement in OS. Eastern Cooperative Oncology Group performance status ≥1, serum hemoglobin < 10 g/dL, and age > 75 years predicted worse survival, whereas isolated lymph node metastasis predicted a favorable outcome.

Abstract
Background Platinum-based chemotherapy is the standard treatment for advanced urothelial cancer (UC) and is generally used in the first-line setting. However, the optimal salvage treatment for previously treated UC patients is unclear. We conducted a systematic review of published clinical trials of single agent versus combined chemotherapy as salvage treatment in previously treated UC patients. Methods Trials published between 1994 and 2015 were identified by an electronic search of public databases (MEDLINE, EMBASE, Cochrane library). All relevant studies were independently identified by two authors for inclusion. Demographic data, treatment regimens, objective response rate (ORR), disease control rate (DCR), median progression-free and overall survival (PFS, OS), and grade 3/4 toxicities were extracted and analyzed using Comprehensive Meta Analysis software (Version 2.0). Results Fifty cohorts with 1,685 patients were included for analysis: 814 patients were treated with single agent chemotherapy and 871 with combined chemotherapy. Pooled OS was significantly higher at 1 year for combined chemotherapy than for single agent (relative risk [RR] 1.52; 95% CI: 1.01–2.37; P=0.03) but not for 2-year OS (RR 1.31; 95% CI: 0.92–1.85; P=0.064). Additionally, combined chemotherapy significantly improved ORR (RR 2.25; 95% CI: 1.60–3.18; P<0.001) and DCR (RR 1.12; 95% CI: 1.01–1.25, P=0.033) compared to single agent for advanced UC patients. As for grade 3 and 4 toxicities, more frequencies of leukopenia and thrombocytopenia were observed in the combined chemotherapy than in single agent group, while equivalent frequencies of anemia, nausea, vomiting, and diarrhea were found between the two groups. Conclusion In comparison with single agent alone, combined chemotherapy as salvage treatment for advanced UC patients significantly improved ORR, DCR, and 1-year OS, but not 2-year OS. Our findings support the need to compare combined chemotherapy with single agent alone in the salvage setting in large prospective trials due to its potential survival benefit in advanced UC patients.

Second-Line Chemotherapy for Metastatic Urothelial Carcinoma: Importance of Lymph Node-Only Metastasis as a Prognostic Factor and Construction of a Prognostic Model. Clin Genitourin Cancer 2015; 14:255-60. [PMID: 26552764 DOI: 10.1016/j.clgc.2015.10.006] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2015] [Revised: 10/05/2015] [Accepted: 10/17/2015] [Indexed: 11/16/2022]
Abstract
BACKGROUND A prognostic model for patients with metastatic urothelial carcinoma (UC) progressing after platinum-based therapy was constructed from data from the phase III vinflunine trial. However, prognostic information for patients treated with other regimens is limited. MATERIALS AND METHODS We pooled individual patient data from 7 second-line studies and analyzed the influence of factors of interest on overall survival (OS) through univariate and multivariate analysis. A prognostic model was constructed, and data from an independent series were used for validation. RESULTS The data from 193 patients were pooled. The second-line chemotherapy regimen was single-agent taxane in 54 patients (28%), a platinum-based combination in 47 (24%), and a non-platinum combination in 92 (48%). On multivariate analysis, Eastern Cooperative Oncology Group performance status ≥ 1, hemoglobin < 10 g/dL, and metastatic patterns other than lymph node-only metastasis emerged as independent adverse prognostic factors. Patients with all 3 factors (poor risk), 1 to 2 factors (intermediate risk), and no factors (good risk) had a median OS of 3.1, 8.7, and 16.5 months, respectively (P < .0001). The corresponding median OS for the validation series (n = 44) was 3.3, 8.1, and 13.3 months (P = .023). Furthermore, platinum-based regimens were independently associated with an OS benefit compared with other regimens (hazard ratio, 0.31; 95% confidence interval, 0.18-0.53; P < .0001). CONCLUSION We have proposed and validated a prognostic model for patients with metastatic UC who were eligible for second-line therapy. The proposed model could prove helpful for risk stratification. Furthermore, our data suggest that testing second-line platinum-based regimens in randomized trials is warranted.

Second-line single-agent versus doublet chemotherapy as salvage therapy for metastatic urothelial cancer: a systematic review and meta-analysis. Ann Oncol 2015; 27:49-61. [PMID: 26487582 DOI: 10.1093/annonc/mdv509] [Citation(s) in RCA: 85] [Impact Index Per Article: 8.5] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2015] [Accepted: 10/12/2015] [Indexed: 11/12/2022] Open
Abstract
BACKGROUND The efficacy and safety of a combination of chemotherapeutic agent compared with single-agent chemotherapy in the second-line setting of advanced urothelial carcinoma (UC) are unclear. We aimed to study the survival impact of single-agent compared with doublet chemotherapy as second-line chemotherapy of advanced UC. PATIENTS AND METHODS Literature was searched for studies including single-agent or doublet chemotherapy in the second-line setting after platinum-based chemotherapy. Random-effects models were used to pool trial-level data according to treatment arm, including median progression-free survival (PFS), overall survival (OS), objective response rate (ORR) probability, and grade 3-4 toxicity. Univariable and multivariable analyses, including sensitivity analyses, were carried out, adjusting for the percent of patients with ECOG performance status ≥1 and hepatic metastases. RESULTS Forty-six arms of trials including 1910 patients were selected: 22 arms with single agent (n = 1202) and 24 arms with doublets (n = 708). The pooled ORR with single agents was 14.2% [95% confidence interval (CI) 11.1-17.9] versus 31.9% [95% CI 27.3-36.9] with doublet chemotherapy. Pooled median PFS was 2.69 and 4.05 months, respectively. The pooled median OS was 6.98 and 8.50 months, respectively. Multivariably, the odds ratio for ORR and the pooled median difference of PFS were statistically significant (P < 0.001 and P = 0.002) whereas the median difference in OS was not (P = 0.284). When including single-agent vinflunine or taxanes only, differences were significant only for ORR (P < 0.001) favoring doublet chemotherapy. No statistically significant differences in grade 3-4 toxicity were seen between the two groups. CONCLUSIONS Despite significant improvements in ORR and PFS, doublet regimens did not extend OS compared with single agents for the second-line chemotherapy of UC. Prospective trials are necessary to elucidate the role of combination chemotherapy, with or without targeted agents, in the salvage setting. Currently, improvements in this field should be pursued considering single-agent chemotherapy as the foundation for new more active combinations.

Abstract
PURPOSE Prognostic factors in patients receiving salvage systemic therapy for advanced urothelial carcinoma include performance status, liver metastasis, hemoglobin and time since chemotherapy. We investigated the impact of albumin, and neutrophil, lymphocyte and platelet counts. MATERIALS AND METHODS Patient level data from 10 phase II trials were used. Cox proportional hazards regression was applied to evaluate associations with overall survival. An optimal regression model was constructed using forward stepwise selection and risk groups were defined using the number of adverse factors. Trial was a stratification factor. External validation was done in a separate data set of 5 salvage phase II trials. RESULTS Discovery data were obtained on 708 patients. After adjustment for the 4 known factors a platelet count of the upper limit of normal or greater and albumin less than the lower limit of normal were significant poor prognostic factors. Only the addition of albumin was externally validated. For 0 or 1, 2 and 3 or greater risk factors median overall survival was 8.9, 6.4 and 4.5 months in 207, 171 and 113 patients in the discovery data set of 491, and 10.6, 10.0 and 7.0 months in 73, 47 and 47 patients, respectively, in the validation data set of 167. By adding albumin the c-index improved from 0.610 to 0.639 in the discovery set and from 0.616 to 0.646 in the validation set. CONCLUSIONS Albumin was externally validated as a prognostic factor for overall survival after accounting for time from prior chemotherapy, hemoglobin, performance status and liver metastasis status in patients receiving salvage systemic therapy for advanced urothelial carcinoma. The discovery of molecular prognostic factors is a priority to further enhance this new preferred 5-factor clinical prognostic model.

Abstract
BACKGROUND Single-agent taxanes are commonly used as salvage systemic therapy for patients with advanced urothelial carcinoma (UC). OBJECTIVE To study the impact of combination chemotherapy delivering a taxane plus other chemotherapeutic agents compared with single-agent taxane as salvage therapy. DESIGN, SETTING, AND PARTICIPANTS Individual patient-level data from phase 2 trials of salvage systemic therapy were used. INTERVENTIONS Trials evaluating either single agents (paclitaxel or docetaxel) or combination chemotherapy (taxane plus one other chemotherapeutic agent or more) following prior platinum-based therapy were used. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Information regarding the known major baseline prognostic factors was required: time from prior chemotherapy, hemoglobin, performance status, albumin, and liver metastasis status. Cox proportional hazards regression was used to evaluate the association of prognostic factors and combination versus single-agent chemotherapy with overall survival (OS). RESULTS AND LIMITATIONS Data were available from eight trials including 370 patients; two trials (n=109) evaluated single-agent chemotherapy with docetaxel (n=72) and cremophor-free paclitaxel (n=37), and six trials (n=261) evaluated combination chemotherapy with gemcitabine-paclitaxel (two trials, with n=99 and n=24), paclitaxel-cyclophosphamide (n=32), paclitaxel-ifosfamide-nedaplatin (n=45), docetaxel-ifosfamide-cisplatin (n=26), and paclitaxel-epirubicin (n=35). On multivariable analysis after adjustment for baseline prognostic factors, combination chemotherapy was independently and significantly associated with improved OS (hazard ratio: 0.60; 95% confidence interval, 0.45-0.82; p=0.001). The retrospective design of this analysis and the trial-eligible population were inherent limitations. CONCLUSIONS Patients enrolled in trials of combination chemotherapy exhibited improved OS compared with patients enrolled in trials of single-agent chemotherapy as salvage therapy for advanced UC. Prospective randomized trials are required to validate a potential role for rational and tolerable combination chemotherapeutic regimens for the salvage therapy of advanced UC. PATIENT SUMMARY This retrospective study suggests that a combination of chemotherapy agents may extend survival compared with single-agent chemotherapy in selected patients with metastatic urothelial cancer progressing after prior chemotherapy.

Abstract
While platinum-based combination chemotherapy leads to high response rates in patients with advanced urothelial cancer of the bladder, most patients will ultimately progress and optimal treatment in the second-line setting still needs to be determined. Advanced age, poor performance status, comorbidities and rapidly progressive disease have rendered accrual into trials difficult. Vinflunine is the only cytotoxic agent to demonstrate survival benefit in a randomized Phase III setting, but its response rate is disappointing and it has not been compared with other currently used agents such as taxanes. Recent years have seen a better definition of prognostic and predictive factors in patients with relapsed urothelial cancer. In addition, several trials have investigated novel biological agents to target chemoresistant disease. This review provides an update on the current systemic management of advanced urothelial cancer on progression following first-line chemotherapy, and discusses emerging data from recent Phase II/III trials.

Pegylated liposomal doxorubicin as third-line chemotherapy in patients with metastatic transitional cell carcinoma of urothelial tract: results of a phase II study. Med Oncol 2013; 30:407.

Abstract
Until the recent approval of vinflunine, no standard second-line chemotherapy existed for advanced transitional cell carcinoma (TCC). Few data exist about third-line chemotherapy for metastatic disease. Although administered in up-front regimens, anthracyclines were never evaluated beyond second-line treatment. This study assessed the activity of pegylated liposomal doxorubicin (PLD) in patients with advanced TCC previously treated with two chemotherapy regimens. From May 2005 to June 2009, 23 patients with metastatic TCC were recruited: median age was 62 years (49-76 years) with a median ECOG PS of 1. Patients received PLD 35 mg/m(2) every 21 days. All patients were evaluable for efficacy and toxicity. No patient showed complete response. Three patients (13 %) had partial response; seven patients (30 %) showed stable disease for a disease control rate of 43 %. The median time to progression (TTP) was 4.1 months with a median survival time (MST) of 6.3 months. Treatment was well tolerated: no patient developed grade 4 toxicities. This is the first study which evaluated the role of anthracyclines as third-line chemotherapy in metastatic TCC. Despite its manageable profile of toxicity, PLD showed modest activity. Beyond second-line chemotherapy, supportive care still represents the best therapeutic option for patients with metastatic TCC.

Abstract
BACKGROUND We retrospectively evaluated the efficacy and toxicity of paclitaxel plus doxorubicin as a second-line treatment in patients with urothelial carcinoma, who had not responded to a prior platinum plus gemcitabine combination. PATIENTS AND METHODS All patients received intravenous infusions of paclitaxel (175 mg/m(2)/h) and doxorubicin (50 mg/m(2)/30 min) on day 1. Chemotherapy courses were repeated every 21 days. RESULTS The median followup duration was 13.5 months (range 2.8-22.4 months). Complete and partial responses were observed in 2 (5.6%) and 10 (27.8%) patients, respectively. Median overall survival was 8.9 months (95% confidence interval (CI): 6.2-11.6). Median time to progression was 3.8 months (95% CI: 2.7-4.8). The most common hematologic toxicities were neutropenia (n = 21, 58.3%), thrombocytopenia (n = 10, 27.8%), and anemia (n = 9, 25%). The most common nonhematologic toxicities consisted of fatigue (n = 15, 41.7%), nausea/vomiting (n = 13, 36.1%), peripheral neuropathy (n = 11, 30.6%), and mucositis (n = 6, 16.7%). Dose reductions by 25-35% were performed in 6 (16.7%) patients because of grade 3/4 toxicity. Anthracycline-related heart failure did not occur. CONCLUSION 3-weekly courses of cyclic paclitaxel plus doxorubicin were found to be effective and tolerable in patients with urothelial carcinoma, who had not responded to prior platinum- and gemcitabine-based chemotherapy.
