Background : Recent SIOPEL studies have shown cisplatin monotherapy to be equally effective in management of Standard risk Hepatoblastoma (SRHB)as compared to PLADO. Aims and Objectives: To study the chemotherapy, response and outcomes in children with SRHB. Material and Methods: A retrospective study was conducted and all children with SRHB who presented to us from June 2007 to December 2017 were included. All patients with standard risk hepatoblastoma who had received at least 2 cycles of chemotherapy were included. Data regarding the demographics, PRETEXT stage, chemotherapy, response to chemotherapy and outcomes were recorded. Kaplan Meier survival analysis was performed to calculate 5 year overall survival (OS) and event free survival (EFS). Results: Thirty two children were included in the study. The disease was PRETEXT I in 5 (15.6%), II in 9 (28.1%) and 18 (56.2%). Nineteen children (59.4%) received Cisplatin monotherapy and of these 6 patients (all PREXT III) had poor response and the chemotherapy was upgraded to PLADO. The remaining 13 (40.6%) received upfront PLADO chemotherapy. Only 31 patients could be operated. Tumor recurred in 5 patients, 2 who had upfront PLADO and 3 patients had been upgraded to PLADO. The 5 year OS and EFS was 100% in the monotherapy group (n=13), 92% and 69% in the upfront PLADO group (n=13), and 62% and 22% in the upgraded to PLADO group (n=6). Patients with PRETEXT III disease in whom chemotherapy was upgraded to PLADO had significantly lower survival (p=0.036) compared to those who received upfront PLADO chemotherapy. Conclusion: Two thirds of patients with PRETEXT stage III who received cisplatin monotherapy showed poor response and were upgraded to PLADO chemotherapy. These patients had a significantly poorer outcome compared to the rest of the cohort. PRETEXT stage III standard-risk hepatoblastoma may benefit from PLADO chemotherapy instead of cisplatin monotherapy.
