放射治疗使许多绝望的癌症患者获得新生或减轻痛苦延长生命。但也使极少数患者因放疗而诱发第2种原发癌。有关这方面的病例随着放射肿瘤学的不断进展已偶有报道,现将我科收治的4例鼻咽癌患者因放疗后诱发癌变的病例作一报道。 临床资料 例1,女,56岁,1971年6月诊为鼻咽低分化鳞癌,同年9月至11月在外院行~(60)Co外照射,给鼻咽部剂量64Gy/46天/34次。肿瘤消失。1983年3月起觉左鼻塞、流黄涕带血丝,嗅觉减退。同年8月来本院就诊。
Radiation therapy makes many desperate cancer patients get new or relieve pain and prolong life. However, it also causes a very small number of patients to induce the second type of primary cancer due to radiotherapy. Related cases in this area have been reported occasionally with the constant progress of radiation oncology, and 4 cases of patients with nasopharyngeal carcinoma admitted to our department have been reported for cases of cancer induced by radiotherapy. Clinical data Example 1, female, 56 years old, was diagnosed with poorly differentiated squamous cell carcinoma of the nasopharyngeal in June 1971, and was exposed to external (60) Co in an external hospital from September to November of the same year. The dose to the nasopharynx was 64 Gy/46 days/ 34 times. The tumor disappeared. In March 1983, he felt left nasal congestion, flow jaundice with bloodshots, and the sense of smell decreased. In August of the same year, he came to the hospital.
