鼻咽癌为我省常见的恶性肿瘤之一,约占我科放疗病人的1/5。目前鼻咽癌五年生存率不高的原因之一是原灶复发。据报导原灶复发是鼻咽癌的主要死因之一,占19～34.4％,仅次于远处转移。放疗是治疗鼻咽癌的主要方法,虽经放疗但仍有一部分病人在放疗后的不同时期出现原灶复发,而目前国内分析原灶复发的资料不多。本文探讨鼻咽癌病人放疗后原灶复发与原灶大小,分期,病理类型和照射剂量的关系。材料与方法本文根据我院肿瘤科自1971—1～1980—12底为止共收治鼻咽癌患者2152例,其中原灶复发或原灶和颈淋巴结同时复发者共102例(占4.5％)。再次经病理证实者44例,根据临
Nasopharyngeal carcinoma is one of the most common malignancies in our province and accounts for about one-fifth of patients in our department. One of the reasons for the low 5-year survival rate of nasopharyngeal carcinoma is the recurrence of the original tumor. It has been reported that the recurrence of the foci is one of the major causes of death from nasopharyngeal carcinoma, accounting for 19 to 34.4%, second only to distant metastases. Radiotherapy is the main method for the treatment of nasopharyngeal carcinoma. Although radiotherapy has been performed, some patients still have recurrences of the original lesions at different times after radiotherapy. However, there are few data on the recurrence of the original lesions in the country. This article discusses the relationship between the recurrence of primary tumor and the size, staging, pathological type and irradiation dose of nasopharyngeal carcinoma patients after radiotherapy. Materials and Methods According to the 2152 cases of nasopharyngeal carcinoma patients from the Department of Oncology in our hospital from the end of 1971-1 to 1980-12, there were 102 cases (4.5%) of recurrent tumors or recurrences of primary tumors and cervical lymph nodes. 44 cases confirmed by pathology again, according to
