Real World Experience of Treating Neuroblastoma: Experience from a Tertiary Cancer Centre in India.

Abstract：

OBJECTIVES:Management of neuroblastoma, especially high-risk (HR) disease is difficult in a resource-limited setting. There is a paucity of literature on outcomes of patients treated in India. The present study was conducted to analyse the clinical profile, treatment, and outcomes of patients with neuroblastoma treated at authors' centre. METHODS:The study was a retrospective analysis of newly diagnosed patients with neuroblastoma treated at authors' centre between 2000 to 2017. The International Neuroblastoma Staging System and risk grouping were used to classify patients as low-risk (LR), intermediate-risk (IR) and high-risk (HR). Treatment was individualised and risk-adapted. Kaplan-Meier method was used to calculate the event-free survival (EFS) and overall survival (OS). RESULTS:The study included 85 patients with a median age of 4 y and 67% were males. Malnutrition was observed in 55% of patients. Adrenal gland was the most common site in 75% patients followed by mediastinum in 12%. LR was observed in 7/85 (8%) patients, IR 20/85 (24%) and HR in 58/85 (68%) patients. The CCG-3891 protocol was used to treat 80% of the patients. Autologous stem cell transplantation (ASCT) was performed in 32% of HR patients. The median follow-up was 16.6 mo. The median EFS and OS for all patients were 19.2 mo and 26.9 mo respectively and the 3 y EFS and OS was 36% and 47% respectively. The 3y EFS for LR, IR and HR patients was 100%, 54%, and 18.9% respectively (P < 0.001) and for OS was 100%, 77%, and 34% respectively (P = 0.002). On multivariate analysis, a hemoglobin less than 10 g% predicted inferior EFS (P = 0.002) and OS (p = 0.005) for all patients. For patients with high-risk disease, on multivariate analysis, hemoglobin (P = 0.002) and 13-Cis Retinoic acid maintenance (P = 0.002) predicted EFS and only radiotherapy to the primary (P = 0.01) predicted OS. Only 4/19 (21%) are alive and in remission post ASCT. CONCLUSIONS:Majority of patients with neuroblastoma presented to authors' centre with advanced disease. Survival outcomes of patients with LR disease are excellent. However, patients with HR disease have poor outcomes despite multimodality management. Non-availability of N-MYC testing in few patients could have falsely down-staged them to IR from HR. A low hemoglobin at diagnosis is a poor predictor of outcome.
