Clinicoepidemiological Profile and Outcome of Children With Wilms Tumor in a Developing Country

Background: Outcome of children with Wilms tumor (WT) has improved remarkably because of the advancements in Pediatric Oncology. However, in most developing countries survival rates are still poor. There is a paucity of data regarding the clinical profile and outcome of children with WT in India. Methods: Children with WT who were treated at our center between 2005 and 2014 were retrospectively analyzed. Results: Over the 10-year study period, 108 children with WT were treated in our unit. The median age at presentation was 30 months (male: female ratio of 4: 1). Abdominal mass was the most common presenting feature (91%). The majority of children had stage 2 (30%) or stage 3 (35%) disease. Fifty-nine children had large or bilateral tumors requiring preoperative chemotherapy. Of the total 108 children, 11 died during primary treatment and 14 relapsed after completion of treatment. The projected 5-year overall survival is 74%, whereas the event-free survival is 73%. Conclusions: Children with WT in our setting present late with advanced disease and large tumors, which are technically difficult to deliver at surgery. With a multidisciplinary approach, reasonably good survival rates were achieved even in the resource-limited Indian scenario.
