子宫颈癌盆腔淋巴结清除数的探讨

A study on the number of lymph nodes excised in pelvic lymphadenectomy for cervical carcinoma

本文回顾性分析43例施子宫广泛性切除及盆腔淋巴结清除术的子宫颈癌患者的临床资料,统计其盆腔淋巴结清除数及阳性数。结果:43例中8例有淋巴结转移,转移率18.6%。43例共清除淋巴结576个,平均13.4个。阳性淋巴结21个(3.65%),其中右侧308个,阳性8个(2.60%),左侧268个,阳性13个(4.85%)。鳞癌29例,淋巴结转移3例(10.34%),腺癌14例,淋巴结转移5例(35.71%)。阳性淋巴结最小直径2mm,最大31mm。鳞癌淋巴结转移左侧居多,而腺癌左右侧相似。临床期别越晚,淋巴结转移越多。提示:临床与病理对盆腔淋巴结的检出率受多种因素综合影响,而盆腔淋巴结转移与组织类型、临床期别及淋巴结解剖部位等有关。

To evaluate the number of lymph nodes excised in pelvic lymphadenectomy for cervical carcinoma.Design:43 cases of cervical carcinema un- derwent radical hysterectomy and pelvic lymphadenec- tomy in the women's hospital affiliated to Zhejiang Medical University.Total and positive numbers of pelvic lymph nodes excised were retrospectively calcu- lated and analyzed.Results:The total number of lymph nodes excised was 576 (mean 13.4/case);the total metastatic rate of lymph notes in 43 cases was 18.6% (8/43),the metastatic rate of squamouscaci- noma was 10.34%(3/29),while the rate of adenocar- cinoma was 35.71%(5/14).The number of positive nodes was 21 in 8 cases.The positive rate of lymph nodes in the right side of pelvis was 2.60%(8/308), but that in the left side was 4.85%(13/268).The di- ameters of positive bodes were from 2 to 31 mm.Con- clusion:The metastasis of lymph nodes is associated with histological types ,clinical stages and anatomic lo- cation of lymph nodes.
