421 Background: Aim of this retrospective study was to investigate the clinico-pathological features and the outcome of patients (pts) with late relapsing renal cell carcinoma (LateR-RCC) treated with vascular endothelial growth factor receptor (VEGFR) tyrosine kinase inhibitor (TKI) as first line therapy. Methods: Data were collected from 19 Italian centers involved in the treatment of metastatic RCC. Late relapse was defined as >5 yr after initial radical nephrectomy. MSKCC prognostic categories were assessed before starting first-line treatment with VEGFR-TKI. Overall survival (OS) and progression free-survival (PFS) were estimated with the Kaplan-Meyer method with 95% CI and curves were compared with log-rank test. A Cox-regression model was applied to the data with a univariate and multivariate approach. Variables included in the univariate analysis were gender, age, time from surgery, MSKCC risk-group and targeted therapy employed at first line. Results: A total of 2,490 pts were screened and 269 pts (11%) were identified as LateR-RCC and treated with first-line VEGFR-TKI. Median age was 66 yr (range 29-87). Median time to recurrence was 7.9 yr. MSKCC prognostic category was good in 63% of pts, intermediate in 31% and poor in 6%. First-line therapy consisted of sunitinib in 190 pts (71%), sorafenib in 58 pts (21%) and pazopanib in 21 pts (8%). The median PFS was 20.0 months (95% CI 17.0−25.1) for sunitinib and 14.1 months for both sorafenib (95% CI 11.0−29.0) and pazopanib (95% CI 11.2−NR). At multivariate analysis, only MSKCC prognostic group was an independent prognostic factor for OS (HR: 2.07; 95% CI, 1.52–2.82 p < 0.001) and PFS (HR 2.54; 95% CI, 1.93−3.36 p < 0.001), whereas first line TKI was not significantly associated with OS (HR: 0.94; 95% CI, 0.38–1.82 p = 0.895) and PFS (HR 0.77; 95% CI, 0.43−1.99 p= 0.547). Conclusions: No significant differences were found in terms of OS and PFS in pts with LateR-RCC treated with first-line sorafenib, sunitinib or pazopanib. Our data may be considered in the long-term management of these patients.

502 Background: Some on-target adverse events such as hypertension or thrombocytopenia have been reported as biomarkers predicting the efficacy of sunitinib as first-line therapy for patients with metastatic renal cell carcinoma (mRCC). Decrease of renal function is a major adverse event of sunitinib. However, it remains unclear whether the degree of deterioration of renal function can predict the anti-tumor efficacy of sunitinib. We investigated the relationship between treatment-related deterioration of renal function and anti-tumor efficacy in mRCC patients treated with sunitinib. Methods: We retrospectively reviewed the medical records of mRCC patients who were treated with sunitinib for more than 3 months. Patients receiving hemodialysis before receiving sunitinib as well as those who did not undergo nephrectomy were excluded from our analysis. Renal function was evaluated by the estimated glomerular filtration rate (eGFR) calculated using the MDRD equation modified for Japanese patients. The degree of deterioration in eGFR was compared with progression-free survival (PFS). Results: Sixty-two patients were enrolled, the median age was 65 years, and 44 patients (71%) were male. The median baseline eGFR was 49.1 ml/min/1.73m2, and median decrease of eGFR was 9.9 ml/min/1.73m2. Forty-seven patients (76%) had a decreased eGFR of more than 10% compared to baseline values. The patients showing this decrease had significantly longer PFS than those who did not (PFS: 15.5 months vs. 6.1 months, respectively; p=0.001). On multivariate analysis, a decrease in eGFR of more than 10% was a significant independent factor for predicting longer PFS (hazard ratio, 0.37; 95% confidence interval, 0.17-0.83; p=0.017) as well as MSKCC risk groups and cycles of sunitinib. Conclusions: Treatment-related deterioration of renal function is a biomarker to predict better treatment efficacy for use of sunitinib during first-line therapy for patients with mRCC.

BackgroundImmune checkpoint inhibitors (ICI) are first-line therapy for tumors including metastatic renal cell carcinoma (mRCC). Use of ICI is complicated by diverse immune-related adverse events (irAEs), which can add significant morbidity but are also associated with improved efficacy of therapy.1 2 Risk factors for development of irAE are still poorly understood. We hypothesized that patients with mRCC treated with ICI as first-line therapy have higher rates of developing irAE’s than patients previously treated with other therapies.MethodsWe conducted a single-institution, retrospective medical record review of patients with mRCC treated with immune-checkpoint inhibitors from March 2011 through April 15, 2020. We identified therapy duration, and presence, severity, and treatment of adverse events. We defined overall survival as time elapsed from date of diagnosis until death or until completion of study. We classified severity of adverse events according to CTCAE guidelines. Statistical methods included univariate Cox proportional hazards and logistic regression models, and Kaplan-Meier curves were plotted for subgroups.ResultsA total of 64 unique charts were reviewed. 18 patients (28%) of patients were treated with ICI as first-line therapy. 28 patients (44%) experienced immune-related adverse events with a total of 40 irAE’s identified. Most irAE were grade I-II (78%), with 7 (17%) grade III and 1 (2.4%) grade IV irAE’s. Most common sites were skin (29%), thyroid (20%) and gastrointestinal (15%). Patients with irAE had increased survival compared to those who did not have irAE (median survival not reached, vs 139 weeks, p=0.0004) (figure 1). This finding remained after excluding patients who had only experienced dermatologic irAE (median survival not reached in non-derm irAE subgroup, vs 144 weeks for dermatologic or no irAE, p=0.01) (figure 2). Patients treated with ICI as first line therapy had greater rates of developing irAE (72%) than those who had prior therapies (32%) (OR 5.4; p = 0.006). There was no association between histology type and rate of irAE.Abstract 191 Figure 1Kaplan-Meier survival plot of OS between patients with any irAE and those without any irAEAbstract 191 Figure 2Kaplan-Meier survival plot of OS between patients with non-dermatologic irAE and those without any irAE or only dermatologic irAEConclusionsThe development of irAE’s in patients with mRCC treated with ICI is associated with longer survival. This study joins the growing body of evidence showing that presence of irAE’s is associated with increased treatment efficacy. Use of ICI as first-line therapy is associated with higher risk of irAE. Given growing use of ICI as first-line therapy, further study to predict onset and severity of irAE’s is required.AcknowledgementsHong Wang, PhD, for statistical support.Ethics ApprovalThis study was approved by the University of Pittsburgh Institutional Review Board.
