Abstract

Introduction Neuroblastoma is the most common extracranial solid tumor in childhood. The data on the treatment experience with 131iodine-meta-iodo-benzyl-guanidine (131I-mIBG) and clinical outcome data are meager from India.

Objectives This article studies the efficacy and treatment outcomes in patients treated with 131I-mIBG in high-risk neuroblastoma.

Materials and Methods The study group consisted of 201 consecutive patients (aged between 1 and 15 years) with biopsy-proven neuroblastoma who underwent 131I-mIBG scans from 2012 to 2022. The majority of these children had a disease that was inoperable or had poor response to chemotherapy. Patients with positive scintigraphy were considered for therapy with 131I-mIBG. The findings were analyzed and correlated with the final diagnosis and outcomes obtained from survival during follow-up and reviewing patient records.

Results Thirty-nine children, 22 males and 17 females, with a median age of 4 years had positive 131I-mIBG scintigraphy. Intra-abdominal primary lesions and osseous lesions were the most common sites of uptake on 131I-mIBG scan. Of these, 13 had upfront chemotherapy and 26 had surgery followed by chemotherapy. All the patients underwent therapy with 131I-mIBG. Fourteen patients had multiple therapies while the remaining 25 had only one therapy. Eight patients had no follow-up, and 13 had disease relapse. The remaining 18 had regression of disease which was confirmed by follow-up 131I-mIBG scintigraphy and with bone scintigraphy in patients with osseous metastases.

Conclusion131I-mIBG scintigraphy should be preferred in intermediate and high-risk neuroblastoma to know the extent of the disease and also for patient selection for early therapy with 131I-mIBG. It holds significant utility in the management of metastatic neuroblastoma, facilitating palliative pain relief and tumor size reduction in inoperable or metastatic disease.
