Methods We analyzed histologically confirmed WT cases managed from January 2008 to June 2017. Results There were 45 patients, peak age incidence of 2 to 5?years who presented after mean symptom duration of 4.9 months (range, 1–12 months), with mean tumor weight of 1040?g (range, 350–4200?g). Overall, 14 (31.1%) had unfavorable histology of WT. A total of 22 (48.9%) patients received preoperative chemotherapy, 43 (95.6%) received postoperative chemotherapy based on stage of disease and histopathology, but none received adequate radiotherapy. Of these, 19 (44.2%) patients complied with chemotherapy regimen, 15 (33.3%) were lost to follow‐up and 12 (26.7%) cases relapsed. With 30 cases available for evaluation and mean follow‐up duration of 23?months (range, 6–80 months), the overall 5‐year survival is 53.3% (16 cases). Survival in children who complied with postoperative chemotherapy was 73.7%, and abandonment‐sensitive survival was 35.6%. Persisting challenges were late presentation, poor compliance to treatment, and lack of radiotherapy treatment. Conclusion Multidisciplinary team management and chemotherapy based on tumor histology might have resulted in slight improvement of outcome since our last report. However, to ensure survival that may approach global benchmarks, there is need for public health measures to improve time to diagnosis, and improvement of facilities and healthcare funding to ensure compliance to all phases of standard therapy. 收起
