Clinical Profile and Outcomes of Childhood Wilms Tumors Treated in a Tertiary Cancer Center from North India.

In India and other lower-middle-income countries, the progress in the management of Wilms tumor (WT) has lagged behind when compared to the developed countries. In the current study, we highlight the outcomes of 61 children with WT treated at an oncological center in northern India. Our study found that the patient demographics, including age and gender distribution, closely paralleled other Indian studies. Notably, 24% of patients had distant metastasis at diagnosis. An upfront biopsy was performed in majority of the patient with a remarkable concordance rate of over 90%, with no significant complications associated with the procedure. Our surgical approach, guided by image-defined risk factors, resulted in 84% of patients undergoing delayed surgery after chemotherapy. Notably, the incidence of intraoperative complications, including tumor spill, was minimal. Treatment abandonment and toxic death due to sepsis emerged as significant challenges, affecting 22% and 7% of our patient cohort, respectively. The 3-year event-free survival (EFS) and overall survival were 70% and 84%, respectively. The age group of 6 to 8 years and stage V disease emerged as adverse factors influencing EFS. In summary, our study highlights the multifaceted nature of WT management in resource-constrained settings with survival rates promising but still lagging behind high-income countries. Addressing challenges such as treatment abandonment and reducing toxic death is imperative to enhance outcomes of WT in India.
