100例肺癌临床及放射治疗分析

Radiotherapy of Lung Cancer

我院1977年～1987年收治的肺癌^(60)Co外放射总量在4000cGy以上者100例,男90例、女10例,50岁～59岁为高峰年龄组、占41％。治疗采用胸前垂直,背部成角照射方式,总剂量4000～8500cGy/4～8周,随访结果经统计学处理,1、3、5年生存率分别为18.31％、13.53％和11.07％,其中以6000cGy～6900cGy剂量组的5年生存率最高。经检查多数患者细胞免疫值偏低,以扶正治疗增强免疫力提高了疗效。本组患者吸烟率85％,每天5支～40支,同样显示出吸烟与肺癌的密切关系。

From 1977 to 1987, 100 cases of lung cancer were treated by ^(60)Co external beam irradiation with dosages exceeding 4, 000 cGy. There were 90 males and 10 females. The peak age was 50-59 yrs, which accounted for 41% of the series. The external irradiation beam was perpendicular to the chest in the anterior field and oblique on the pos- terior fields. The total dose given was 4, 000-8, 500 cGy/4-8wks. The1-, 3-, and5-year survival rates were 18. 31%,13.53%, and11. 07% respectivey. The highest 5-year survival rate was in the group with dosages of 6,000-6. 900cGy. A majority of the patients in this series hed immuno--deficiency, Fu-Zheng treatment may be necessary in order to enhance the patients' immunity and thereby to improve their response to therapy. 85% of cases were mild or heavy smok- crs consuming 5 to 40 cigaretts per day,a fact that demonstrates close relationship between smoking and lung cancer.
