作者1971～1983年,对90例T_1T_2声门鳞癌作了根治性放疗。按1983年AJC分期,T_1期病变再分为T_(1a)(限于一侧声带)与T_(1b)(侵犯双侧声带);T_2期再分为T_(2a)(声带活动正常)与T_(2b)(声带活动损害)。5例用~(60)Co、85例用4MV,设一单野照射,大小均为5 cm×5cm,双侧病变者,野设在较重的一侧,如两侧病变相似,则任意选择,一周照3次,每次333cGy,在2.5cm深处计量,总量70Gy/6周。本组中数随访期51.5个月,11例未作局控分析,7例因两年内死于间发病,4例随访不到2年(原发瘤均控制),故最后可评价者为79例。全组总的局控率91%(72/79),T_(1a)为92%
From 1971 to 1983, radical radiotherapy was performed on 90 patients with T_1T_2 glottic carcinoma. According to the 1983 AJC staging, T_1 lesions were further divided into T_(1a) (limited to one vocal cord) and T_(1b) (invaded bilateral vocal cords); T_2 period was further divided into T_(2a) (normal vocal cord activity) and T_ (2b) (vocal damage). Five patients with 60Co and 85 with 4MV were treated with single field irradiation. The size of the lesions was 5 cm × 5 cm. The bilateral lesions were located on the heavier side. If the lesions on both sides were similar, the The choice was taken 3 times a week, 333 cGy each time, and measured at a depth of 2.5 cm, for a total of 70 Gy/6 weeks. In the follow-up period of 51.5 months in this group, 11 cases had no local control analysis, 7 cases died of inter-invasion within 2 years, and 4 cases were followed up for less than 2 years (primary tumors were controlled), so the final evaluable person was 79. example. The overall control rate for the whole group was 91% (72/79), and T_(1a) was 92%.
