  Background: In Nasopharyngeal Carcinomas (NPC), due to its anatomical location and radio sensitivity, the primary treatment modality is radical radiotherapy. Intensity Modulated Radiotherapy (IMRT) provides excellent loco regional control and sparing of Organs at Risk (OARs) and it has become the technique of choice for radiotherapy of NPCs. Still late toxicities can occur in up to 40% of patients. The present study analyses the organ at risk doses achieved in patients with NPC treated with IMRT. Materials and Methods: A retrospective audit of NPC treated with IMRT from January 2013 to August 2018 was done. The prescription dose for PTV HR, PTV IR and PTV LR were 69.3 Gy, 59.4Gy and 54 Gy respectively in 33 fractions. Concurrent chemotherapy was added for patients with stage II and above with Cisplatin 100 mg /m2 every 21 days. OAR constraints were restricted to the tolerance doses as.. Read More»
