Nasopharyngeal Radiation-Induced Sarcoma: A Case Report.

ABSTRACT

The primary treatment for nasopharyngeal carcinoma (NPC) is radiotherapy. In rare cases, patients with NPC treated with radiotherapy may develop radiation-induced sarcoma (RIS), a malignant tumor, in the field of previous radiation. The prognosis is poor, and complete surgical resection is the only potentially curative treatment. We report a case of radiation-induced nasopharyngeal sarcoma after radiotherapy for NPC with suspected lung and liver metastases in a 69-year-old woman.
