Cytoreductive nephrectomy in patients with synchronous metastases from renal cell carcinoma: Results from the International Metastatic Renal Cell Carcinoma Database Consortium
Background The benefit of cytoreductive nephrectomy (CN) for overall survival (OS) is unclear in patients with synchronous metastatic renal cell carcinoma (mRCC) in the era of targeted therapy. Objective To determine OS benefit of CN compared with no CN in mRCC patients treated with targeted therapies. Design, setting, and participants Retrospective data from patients with synchronous mRCC (n = 1658) from the International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) were used to compare 982 mRCC patients who had a CN with 676 mRCC patients who did not. Outcome measurements and statistical analysis OS was compared and hazard ratios (HRs) adjusted for IMDC poor prognostic criteria. Results and limitations Patients who had CN had better IMDC prognostic profiles versus those without (favorable, intermediate, or poor in 9%, 63%, and 28% vs 1%, 45%, and 54%, respectively). The median OS of patients with CN versus without CN was 20.6 versus 9.5 mo (p < 0.0001). When adjusted for IMDC criteria to correct for imbalances, the HR of death was 0.60 (95% confidence interval, 0.52-0.69; p < 0.0001). Patients estimated to survive <12 mo may receive marginal benefit from CN. Patients who have four or more of the IMDC prognostic criteria did not benefit from CN. Data were collected retrospectively. Conclusions CN is beneficial in synchronous mRCC patients treated with targeted therapy, even after adjusting for prognostic factors. Patients with estimated survival times <12 mo or four or more IMDC prognostic factors may not benefit from CN. This information may aid in patient selection as we await results from randomized controlled trials. Patient summary We looked at the survival outcomes of metastatic renal cell carcinoma patients who did or did not have the primary tumor removed. We found that most patients benefited from tumor removal, except for those with four or more IMDC risk factors. © 2014 Published by Elsevier B.V. on behalf of European Association of Urology
Survival outcome and treatment response of patients with late relapse from renal cell carcinoma in the era of targeted therapy
Background A subset of primarily localized renal cell carcinoma (RCC) patients will experience disease recurrence ≤5 yr after initial nephrectomy. Objective To characterize the clinical outcome of patients with late recurrence beyond 5 yr. Design, setting, and participants Patients with metastatic RCC (mRCC) treated with targeted therapy were retrospectively characterized according to time to relapse. Relapse was defined as the diagnosis of recurrent metastatic disease >3 mo after initial curative-intent nephrectomy. Patients with synchronous metastatic disease at presentation were excluded. Patients were classified as early relapsers (ERs) if they recurred within 5 yr; late relapsers (LRs) recurred after 5 yr. Outcome measurements and statistical analysis Demographics were compared with the Student t test, the chi-square test, or the Fisher exact test. The survival time was estimated with the Kaplan-Meier method, and associations with survival outcome were assessed with univariable and multivariable Cox regression analyses. Results and limitations Among 1210 mRCC patients treated with targeted therapy after surgery for localized disease, 897 (74%) relapsed within the first 5 yr and 313 (26%) (range: 5-35 yr) after 5 yr. LRs presented with younger age (p < 0.0001), fewer with sarcomatoid features (p < 0.0001), more clear cell histology (p = 0.001), and lower Fuhrman grade (p < 0.0001). Overall objective response rates to targeted therapy were better in LRs versus ERs (31.8% vs 26.5%; p = 0.004). LRs had significantly longer progression-free survival (10.7 mo vs 8.5 mo; p = 0.005) and overall survival (OS; 34.0 mo vs 27.4 mo; p = 0.004). The study is limited by its retrospective design, noncentralized imaging and pathology review, missing information on metastatectomy, and nonstandardized follow-up protocols. Conclusions A quarter of patients who eventually developed metastatic disease and were treated with targeted therapy relapsed over 5 yr from initial nephrectomy. LRs have more favorable prognostic features and consequently better treatment response and OS. © 2013 European Association of Urology
