本文目的是探讨489例Ⅰ_a 期宫颈鳞癌不同手术范围的疗效。诊断的标准是癌细胞突破宫颈上皮基底膜向间质内浸润深度在3毫米以内。诊断的方法是点状活检及锥切检查。资料示点状活检漏诊宫颈浸润癌的可能性在1.5～2.7%之间,而锥切检查无漏诊浸润癌。5例有脉管内浸润,8例有阴道断端残留癌,术后都作了放射治疗,至今健在(5～15年)。尽管手术范围有所不同,但无因本病死亡,5年存活率为99.79%。基于本组489例的经验,建议以扩大全子宫手术作为Ⅰ_a 期宫颈癌的治疗方法。
The purpose of this paper is to investigate the curative effect of 489 cases of stage Ⅰ-a cervical squamous cell carcinoma in different surgical ranges. The diagnostic criteria is cancer cells break through the basement membrane of the cervix into the interstitial infiltration depth of less than 3 mm. The diagnostic method is point biopsy and conization. Data points punctate biopsy missed the possibility of invasive cervical cancer in the 1.5 to 2.7%, while the conization does not miss invasive diagnosis of invasive cancer. 5 cases of vascular infiltration, 8 cases of residual cancer of the vaginal wall, after surgery were radiotherapy, so healthy (5 to 15 years). Although the surgical range is different, but no death due to the disease, 5-year survival rate of 99.79%. Based on the group of 489 cases of experience, it is recommended to expand the uterus surgery as Ⅰ_a cervical cancer treatment.
