Re-Irradiation of Recurrent Nasopharyngeal Cancer: A 4-year Follow-up Study of Treatment using 3-Dimensional Conformal Radiotherapy

Introduction: Nasopharyngeal cancer (NPC) is a prevalent diagnosis of head and neck cancers (HNC) in Asia. In Indonesia, it estimated that there are 12,000 new cases per year. Case Presentation: The author reports 25-year-old male patient with recurrent NPC. This was first diagnosed NPC stage IVB 2013 treated by chemoradiation. 2016, he found another mass his neck. biopsy result showed the recurrence histopathology Undifferentiated carcinoma (WHO type III). Re-irradiation planned, subsequently received 3D-Conformal Radiotherapy (3D-CRT) at our department. Four years after completion re-irradiation, alive well no signs but still complained about late toxicities like trismus fibrotic Conclusions: this study, we discuss use 3D-CRT re-irradiation its limitation on obtaining optimum dose sculpture compared to more sophisticated widely spread modalities intensity-modulated radiotherapy (IMRT). However, careful planning, can obtain tumor dose, minimize organs at-risk (OAR) come after. We hope study bring centers limited facilities, suggest further studies especially OAR tolerance guidelines.
