宫颈癌放疗通常只限于盆腔,而各期宫颈癌都有一部分病人有盆腔外淋巴结亚临床灶存在。用于估计淋巴结转移的静脉造影、淋巴管造影、淋巴结扫描所获结果有一定差别。近年采用开腹探查术作为侦测盆腔外淋巴结转移的手段,但未定出选择这种手术的标准。本文目的在于找出原发病灶组织学分级和发生盆腔外淋巴结转移间的关系。本文取材于1972～1980年间Pennsylvania州立大学医疗中心接收的159例未经治疗、属临床Ⅰ_B～Ⅳ_A期、宫颈鳞状上皮癌患者,治疗前作开腹探查术,同时取主动脉旁淋巴结活检。
Cervical cancer radiotherapy is usually limited to the pelvic cavity, and all cervical cancer patients have pelvic lymph node subclinical lesions exist. There are some differences in the results obtained from venography, lymphangiography, and lymph node dissections used to estimate lymph node metastases. In recent years, laparotomy as a means of detecting extra-pelvic lymph node metastases, but did not set the standard for such surgery. This article aims to identify the primary lesion histological grade and the occurrence of extra-pelvic lymph node metastasis. This article is based on 159 cases of untreated, clinical stage Ⅰ_B-Ⅳ_A cervical squamous cell carcinoma received by the Pennsylvania State University Medical Center between 1972 and 1980. The patients underwent laparotomy before treatment and the para-aortic lymph node biopsy was taken at the same time.
