Background And Purpose:
Wilms tumor is one of the most common solid malignancies of childhood. The long-term result of the surgical treatment of this tumor with adjuvant chemotherapy and radiation has been reported from many western centers. However, there is paucity of literature on the long-term outcome of treatment for this tumor from the developing world. We planned a prospective study that started in 1999 to evaluate the 5-year tumor-free survival of Wilms tumor treated on a fixed protocol from a university hospital in India.
Methods:
All consecutive children with Wilms tumor who were seen by any of the 3 investigators (2 pediatric oncologists, 1 pediatric surgeon) between 1999 and 2003 at the Advanced Pediatric Centre were included in the study. Each patient was entered into a database. Their demographic profile and events during the treatment and follow-up were recorded. This was later analyzed.
Conclusions:
Seventy-five percent 5-year tumor-free survival has been achieved within the limitations of treatment in the developing world. The morbidity during therapy was 10% and the mortality 5%. This was based on the treatment of this common childhood malignancy at Chandigarh on a modified International Society of Pediatric Oncology protocol.
