ABSTRACT
Context: Pediatric solid tumors include a heterogeneous group of tumors, and the burden of these tumors, especially from resource-challenged countries, is not well described. AIMS: The aim of this study was to describe the distribution of solid tumors in children and the treatment outcome of Wilms tumor and hepatoblastoma. Patients and Methods: All patients under 15 years of age with histologically confirmed tumors presenting at a tertiary cancer center from January 2012 to December 2016 were identified from the hospital database. Patients with lymphomas, bone, and central nervous tumors were excluded. The demographic profile including age, sex distribution, and the treatment received were recorded for all patients. Results: The mean age of the eligible 1944 patients was 5.7 years with majority (57.3%) in the 0–4 years age group. The male-to-female ratio was 1.4:1 with a male predominance in all tumors except germ cell tumors. Soft tissue tumors were the most common tumors followed by neuroblastoma and renal tumors, whereas liver tumors formed only 6.7% of all tumors. Seventy percent of the patients received treatment completely or partially at our institute, whereas 18.3% had no cancer-directed treatment. The 3-year overall survival of patients with Wilms tumor and hepatoblastoma was 85.4 and 78.5%, respectively. Conclusions: Extracranial and extraosseous pediatric solid tumors include a wide range of tumors with a predilection for male sex and children below 4 years of age. Soft tissue tumors, neuroblastoma, and renal tumors are the most common; the outcomes of Wilms tumor and hepatoblastoma are favorable.
