Outcomes of Pediatric Renal Tumors over 5 Years in Regional Cancer Center, Kidwai Memorial Institute of Oncology, Bengaluru, South India.

Wilms' tumor (WT) is the most common malignant renal tumor in the pediatric population and it is managed with a multimodal treatment. Improvements in chemotherapy and risk stratification have led to dramatic improvement in the prognosis of renal tumors, which was once a lethal malignancy. Seventy-three patients with histopathologically proven diagnosis of renal tumor who received treatment from January 2011 to December 2015 were included for analysis. Eight children underwent upfront nephrectomy. The patients were analyzed for event-free survival and overall survival. The outcomes were correlated with age, sex, stage at presentation, and histology. A favorable histology was found in 74% patients, while an unfavorable histology was observed in 26% of the cases. The 5-year event-free survival was 82.7% and overall survival was 87.6%. The stage at presentation had a prognostic value ( p  < 0.001). Tumor histology was the single most important factor in predicting the survival.
