A Real-World, Population-Based Retrospective Analysis of Therapeutic Survival for Recurrent Localized Renal Cell Carcinoma After Nephrectomy.

ABSTRACT: We retrospectively analyzed therapeutic strategies and risk factors for overall survival (OS) in disease recurrence following curative nephrectomy for localized renal cell carcinoma (loRCC) using the Korean National Cancer Registry Database. We selected 1295 recurrent loRCC patients who underwent either partial or radical nephrectomy from 2007-2013. Patients were excluded for age <19 years, secondary RCC, multiple primary tumors, other SEER stages except for a localized or regional stage, postoperative recurrence within 3-month, and non-nephrectomized cases. Four therapeutic groups were statistically analyzed for OS and risk factors: surgery (OP, 12.0%), other systemic therapy (OST, 59.5%), radiotherapy (RT, 2.8%), and targeted therapy (TT, 25.8%). The overall mortality rate for recurrent loRCC was 32.5%, including 82.4% for RCC-related deaths. The baseline comparison among groups showed statistical differences for the diagnostic age of cancer and the SEER stage (p<0.05). Multivariate analysis of OS showed significance for the TT (hazard ratio [HR]: 6.27), OST (HR: 7.05), and RT (HR: 7.47) groups compared with the OP group, along with significance for the sex, SEER stage, and the time from nephrectomy to treatment for disease recurrence (p<0.05). The median OS curve showed a significantly better OS in the OP group (54.9 months) compared with the TT, OST, and RT groups (41.7, 42.9, and 38.0 months, respectively; p<0.001). In conclusion, the surgery-treated group had the best OS among the different therapeutic strategies for recurrent loRCC after nephrectomy, and the importance of the time from nephrectomy to secondary treatment was a significant prognostic factor.

Project description:ObjectivesThe treatment landscape for metastatic renal cell carcinoma changed a lot in the last few years. This study aimed to assess the treatment sequences and outcomes for metastatic renal cell carcinoma in a real-world setting.Materials and methodsWe enrolled patients with metastatic renal cell carcinomawho received first-line systemic treatment with tyrosin kinase inhibitors monotherapy, ipilimumab plus nivolumab, or pembrolizumab plus axitinibbetween January2009 and May 2023 on the database of TriNetX network. Overall survival, time on treatment and time to next treatment were evaluated using Kaplan-Meiermethod.ResultsTotally, 4183 received tyrosine kinase inhibitor monotherapy, 1555 received ipilimumab plus nivolumab, and 559 received axitinib plus pembrolizumab. Median time on treatment was 2.5 months for the tyrosine kinase inhibitor monotherapy cohort, 5.4 months for the ipilimumab plus nivolumab cohort, and 8.3 months for the pembrolizumab plus axitinib cohort. Median time to next treatment was 16.6 months for both the tyrosine kinase inhibitor monotherapy and ipilimumab plus nivolumab cohorts, and 22.1 months for the pembrolizumab plus axitinib cohort. Median overall survival was 42.2 months for the tyrosine kinase inhibitor monotherapy cohort, 39.7monthsfor the ipilimumab plus nivolumab cohort, and not reached for the pembrolizumab plus axitinib cohort. In comparison with the tyrosine kinase inhibitor monotherapy cohort, patients in the pembrolizumab plus axitinib cohort showed survival benefit (log-rank p = 0.0168) in overall survival, but not the case in the ipilimumab plus nivolumab cohort.ConclusionThere was a trend toward using first-line immuno-oncology based therapy for patients with metastatic renal cell carcinoma in a real-world practice. Axitinib plus pembrolizumuab cohort had survival benefits over tyrosine kinase inhibitor and ipilimumab plus nivolumab cohorts, while patients in the ipilimumab plus nivolumab cohort had more distant metastases and comorbidities.

Project description:BackgroundAbout 20% of patients with renal cell carcinoma present with non-clear cell histology (nccRCC), encompassing various histological types. While surgery remains pivotal for localized-stage nccRCC, the role of cytoreductive nephrectomy (CN) in metastatic nccRCC is contentious. Limited data exist on the role of CN in metastatic nccRCC under current standard of care.ObjectiveThis retrospective study focused on the impact of upfront CN on metastatic nccRCC outcomes with first-line immune checkpoint inhibitor (IO) combinations or tyrosine kinase inhibitor (TKI) monotherapy.MethodsThe study included 221 patients with nccRCC and synchronous metastatic disease, treated with IO combinations or TKI monotherapy in the first line. Baseline clinical characteristics, systemic therapy, and treatment outcomes were analyzed. The primary objective was to assess clinical outcomes, including progression-free survival (PFS) and overall survival (OS). Statistical analysis involved the Fisher exact test, Pearson's correlation coefficient, analysis of variance, Kaplan-Meier method, log-rank test, and univariate/multivariate Cox proportional hazard regression models.ResultsMedian OS for patients undergoing upfront CN was 36.8 (95% confidence interval [CI] 24.9-71.3) versus 20.8 (95% CI 12.6-24.8) months for those without CN (p = 0.005). Upfront CN was significantly associated with OS in the multivariate Cox regression analysis (hazard ratio 0.47 [95% CI 0.31-0.72], p < 0.001). In patients without CN, the median OS and PFS was 24.5 (95% CI 18.1-40.5) and 13.0 months (95% CI 6.6-23.5) for patients treated with IO+TKI versus 7.5 (95% CI 4.3-22.4) and 4.9 months (95% CI 3.0-8.1) for those receiving the IO+IO combination (p = 0.059 and p = 0.032, respectively).ConclusionsOur study demonstrates the survival benefits of upfront CN compared with systemic therapy without CN. The study suggests that the use of IO+TKI combination or, eventually, TKI monotherapy might be a better choice than IO+IO combination for patients who are not candidates for CN regardless of IO eligibility. Prospective trials are needed to validate these findings and refine the role of CN in current mRCC management.
