宫颈癌三种放射治疗方法疗效的比较──附1254例报告

Therapeutic effect of radiotherapy for cervical cancer

本文对１９７０年１月～１９７３年１２月行放射治疗的１２５４例宫颈癌患者进行了总结和分析，对三种不种放射治疗方法的疗效进行了比较。其中，根治性体外放疗加腔内镭疗组效果最佳，单纯体外放疗组效果最差，五年生存率分别为６７．５％及２７．５％。本文同时还分析了疗效与分期、分型与放射剂量的关系，并对放射剂量作了初步探讨。

Abstract This paper studies 1254 patients with cervical cancer treated by radiation therapy from January 1970 to December 1973. The patients were divided into 3 groups:group 1 external four fieldsvertical radiotherapy plus conventional radium intracaritary irradiation;group 2 vertical radiotherapy of two large fields or cross radiotheragy of 3-,4-, 5-, 6- field plus partial radium therapy;group 3 external beam therapy alone. The results of 3 groups showed that the 5- and 10-yearsurvival rates for group 1, 2 and 3 were 67. 5% and 36. 7%,49. 7% and 19. 6%, 27.5% and 11.7%, respectively. The evident differences of these had statistical significance (P<0. 005). Thetherapeutie effect of group 1 were best among these 3 groups. The later the disease periods,thelower the survival rates. It's suggest that surrival rates be increased by improving techniques andincreasing dose at point A and point B,though sequelac increased.
