早期声门癌的放疗方法和疗效

Radiotherapy for early carcinoma of glottis: treatment methods and results

1974年11月至1993年12月，收治T1N0M0声门癌31例，采用60钴和10MV－X线，大野照射40GY／4周后，缩野再照射20～30GY／2～3周，放疗前或放疗开始给予消炎、脱水治疗和减少声带疲劳，结果，除1例生存6年8个月后复发，行全喉切除，目前已生存10车7个月外，其余均无复发。其生存3、5、10、15年者分别为28／28、16/16、10/11、3/3，生存时间最长者已逾19年。提示：I期声门癌应首选放疗。

From Nov. 1974 through Dec. 1993, 31 patients with T1N0M0 glottic carcinoma were treated in 0ur hospital with 60℃ or 10MV x-ray. Give c0ntinuously DT20 ～30GY/2 ～3wk through area-reduced fields (small field) after completing DT 40GY/4wk through large field. At the same time, infection control dehydration and vocal rest were given. The result showed that 3-, 5-, 10-, 15 years survival rates were 28/28, 16/16, 10/11, 3/3 respectively. Among them, one received total laryngectomy after recurrence 6 years and 8 months later, and has lived for 10 years and 7 months. The longerest survival periods was 19 years. It is suggested that radiotherapy were the first solection to stage I glottic carainoma.
