The epidemiology and outcomes of adult rapid response team patients in a tertiary care hospital in India

To report the overall survival (OS) outcomes of patients with nonclear cell renal cell carcinoma (nccRCC) treated at our institution with a cytoreductive nephrectomy (CN) and better understand the clinical and pathological characteristics of the patients that respond best.We queried our prospectively maintained database for patients who underwent CN for nccRCC between 1989 and 2018. Histology was reviewed by an expert genitourinary pathologist, and nccRCC tumors were subdivided into papillary, unclassified, chromophobe, and other histology. Baseline clinicopathology, treatments, and survival outcomes were recorded. Preoperative hematological parameters including the neutrophil-to-lymphocyte ratio (NLR) were analyzed. Significant univariate predictors of OS were tested in a multivariate model.There were 100 nccRCC patients treated with CN. Median age was 61 years (IQR: 48–69) and 65% were male. There were 79 patient deaths with a median OS of 13.7 months (10.8–27.2). Estimated 2- and 5-year survival was 40.1% and 12.2%, respectively. Median follow-up of survivors was 13 months (IQR: 3–30). On multivariate analysis, increasing NLR (hazard ratio [HR] 1.27; 95% confidence interval [CI] 1.14–1.40, P < 0.001) and sarcomatoid features (HR 2.18; 95% CI 1.19–3.97, P = 0.014) conferred worse OS and the presence of papillary features were a favorable prognostic feature (HR 0.37; 95% CI 0.21–0.65, P < 0.001).OS outcomes in patients with nccRCC who underwent a CN are consistently modest throughout the study period. Patients with papillary features and a lower preoperative NLR may be better candidates for a CN.
