Radiation-Induced Malignancies: Our Experiences With Five Cases

Abstract

Radiotherapy is one of the modalities of treatment of malignancies. Radiation-induced malignancies (RIMs) are late complications of radiotherapy, seen among the survivors of both adult and pediatric cancers. Mutagenesis of normal tissues is the likely basis for RIMs. Till date, RIM cannot be differentiated from primary cancers. We present a series of five patients who were treated at our institute between 2002 and 2016 and were subsequently diagnosed with RIM. Out of five patients, there were two cases of sarcomas, two of carcinomas and one neuroendocrine carcinoma of tongue (rare entity). Separate treatment guidelines are not available for RIM, so the treatment given was same as primary malignancies.
