Survival Outcome of Wilms Tumor with Multi-Modality Treatment at Jimma Hospital, Southwest Ethiopia

Background: Wilms’ tumor (WT), the most common malignant neoplasm of the urinary tract of children [1], accounts for 5.9% of childhood cancers and affects one in every 10,000 children worldwide before the age of 15 years. The care of children with Wilm’s tumor in sub-Saharan Africa is compromised due to resource deficiencies that range from inadequate healthcare budgets to paucity of appropriately trained personnel. Childhood Wilms tumor is surging as an important paediatric problem in developing and sub-Saharan Africa countries. The objective of the study is to establish an understanding on the treatment challenges and outcomes of Wilm’s tumor in South West Ethiopia. Results: Forty-three Wilm’s tumor patients who were admitted from January 2017 to December 2021 were included in the study. The most frequent presentation was painless abdominal swelling in 40 (93%) patients. Fourteen patients (32.6%) were hypertensive at the time of diagnosis and the other 13 (30.2%) were normal. In abdominal examination, 31 (72.1%) patients had abdominal mass not crossing the midline and 12 (27.9%) had mass crossing the midline. After multimodal treatment, 37.5% had improvement, 11.6% came back with relapse. Most patients (41.7%) abandoned treatment and 9.3% of the cohort died in the course of treatment. Conclusion: The outcomes in the treatment of Wilms Tumor have been found to be poor in this review. The main reason for poor outcome has been not receiving adequate chemotherapy after surgery. Doses of chemotherapy received after surgery significantly affected treatment outcomes (p = 0.026).
