Abstract

Objectives: This study aimed to analyze the clinical presentation, diagnostic process, therapeutic approaches, pathological features, and treatment outcomes of children diagnosed with Wilms tumor (WT) and evaluate the time intervals from symptom onset to seeking medical attention and subsequent diagnosis.

Patients and methods: This retrospective study reviewed the records of 18 children (11 males, 7 females; median age: 3.72 years; range, 0.13 to 8.33 years) diagnosed with WT who underwent surgery between January 1, 2010, and December 31, 2023. Data on demographics, clinical presentation, treatment, and outcomes were collected and analyzed. All patients underwent radical nephrectomy and received preoperative and postoperative chemotherapy as per the UMBRELLA protocol of the International Society of Pediatric Oncology Renal Tumor Study Group.

Results: The median age at diagnosis was 37 months. The most common presenting sign was a palpable abdominal mass (100%), followed by abdominal swelling (61%) and distension (67%). The mixed histopathological type was most prevalent (50%). The median time from symptom onset to seeking medical attention was 13.9 days, and the median from initial medical consultation to diagnosis was 9.9 days. Complications occurred in three (17%) patients, and one (6%) patient experienced relapse. The survival rate was 94%.

Conclusion: This study's survival and relapse rates are comparable to global data, reflecting advances in the diagnosis and management of WT at our institution. However, further research is needed to address the study’s limitations and enhance outcomes, particularly in resource-limited settings.
