Abstract: Objective To analyze the long-term efficacy,prognostic factors and radiation sequela of nasopharyngeal carcinoma(NPC)treated with radiotherapy at the end of last century.Methods From January 1995 to December 1998,1706 newly diagnosed NPC patients treated with radiotherapy were included in the retrospective clinical analysis.There were 1081 patients treated with radiotherapy alone,625 with two to three circles of chemotherapy(5-Fu and DDP)before radiotherapy,23 with thermotherapy during radiotherapy and 162 with braehytherapy by 192Ir after external beam radiation.Results The 5-year overall survival. local control survival and disease-free survival rates were 67.60%.84.20%and 64.22%.respectively.The 5-year survival of patients with stage Ⅰ,Ⅱ,Ⅲand Ⅳ(the Fuzhou Staging,1992)were 100%,75.93%,66.47%and 49.34%.respectively.Cox regression analysis showed that the TNM classification,radiotherapy discontinuance,chemotherapy,sex,age and anemia before radiotherapy were the significant factors of survival.Conclusions Our experience shows that the main factors for the long term survival of NPC patients after radiotherapy are early TNM stage,young age,female,non-anemia before radiotherapy, radiotherapy continuance and chemotherapy.
