Disease-Specific Survival in De Novo Metastatic Renal Cell Carcinoma in the Cytokine and Targeted Therapy Era

Abstract Background Nivolumab is a standard treatment for previously treated advanced renal-cell carcinoma. However, nivolumab is effective in only a limited number of patients; therefore, we evaluated the prognostic value of several biomarkers, including inflammation-based prognostic scores and changes in these scores following nivolumab treatment in Japanese patients with metastatic renal-cell carcinoma. Methods We retrospectively reviewed the medical records of 65 patients with previously treated metastatic renal-cell carcinoma and who received nivolumab. Inflammation-based prognostic scores, including neutrophil/lymphocyte ratio, platelet/lymphocyte ratio, lymphocyte/monocyte ratio, and Glasgow prognostic score before and 6 weeks after the treatment were recorded. Categorical variables influencing disease-specific survival were compared using Cox proportional-hazards regression models. Results Univariate analysis showed that Memorial Sloan-Kettering Cancer Center risk score (P = 0.0052), lactate dehydrogenase (P = 0.0266), lymphocyte/monocyte ratio (P = 0.0113), and platelet/lymphocyte ratio (P = 0.0017) had a significant effect on disease-specific survival. Multivariate analyses showed that platelet/lymphocyte ratio and lactate dehydrogenase were found to be independent prognostic factors for disease-specific survival (P = 0.0008, risk ratio (RR) = 7.95, 95% confidence interval, 2.16–51.64 and P = 0.0123, RR = 3.92, 95% confidence interval, 1.37–10.80, respectively). The combination of platelet/lymphocyte ratio and lactate dehydrogenase was the most significant prognostic biomarker in metastatic renal-cell carcinoma (P < 0.0001). Changes in lymphocyte/monocyte ratio and platelet/lymphocyte ratio in response to nivolumab were significant prognostic factors for disease-specific survival (P < 0.0001 and P = 0.0477, respectively). Conclusions The combination of platelet/lymphocyte ratio and lactate dehydrogenase may be a potential biomarker for estimating disease-specific survival in Japanese patients with metastatic renal-cell carcinoma treated by nivolumab.

280 Background: Multiple effective oral anticancer agents (OAAs) are now approved for the treatment of patients with advanced or metastatic renal cell carcinoma (mRCC) based on improvement in overall and progression-free survival in randomized clinical trials. However, real-world adherence and outcomes associated with OAA use in the general mRCC patient population have not been previously investigated. Methods: Retrospective analysis of SEER-Medicare patients with mRCC who received treatment with an OAA between 2007 and 2015. Adherence was assessed as proportion of days covered (PDC) within 3 months of OAA initiation with PDC > 50% categorized as adherent. The impact of initial OAA adherence on overall and disease-specific survival was analyzed landmarked at 3 months after OAA initiation. Results: A total of 905 patients met study criteria, of which 577 (63.8%) were categorized as adherent to initial OAA treatment. Multivariable analysis adjusting for clinical and demographic factors revealed that living within an impoverished neighborhood was associated with a 20% lower likelihood of adherence (OR 0.80, CI 0.68 – 0.93). No association was observed between adherence and race, ethnicity, marital status, or number of comorbidities. In survival analyses OAA adherence was associated with a significant reduction in both overall (HR 0.71, CI 0.58 – 0.87) and RCC-specific mortality (HR 0.68, CI 0.57 – 0.86). Receipt of sunitinib was associated with a significant reduction in overall and disease specific mortality compared with sorafenib. Post-hoc analysis of patients taking pazopanib as their initial OAA (N = 252) demonstrated reduced all-cause mortality if they received the minimum effective dose of 800 mg daily (HR 0.50, CI 0.35 – 0.72) and decreased adherence associated with initial higher out-of-pocket payments (χ2 test, p = 0.003). Conclusions: Socioeconomic factors predict poor adherence to OAA therapy in Medicare beneficiaries with metastatic RCC, which is in turn associated with poor overall and disease-specific survival. Efforts to improve outcomes and mitigate disparities in the general mRCC population should incorporate considerations of OAA adherence and economic factors. Sunitinib and pazopanib appear associated with favorable survival and remain the most commonly used OAAs in this over 65 year old patient population.
