Clinical Analysis On The Multiple Factors Of Fertility Preserving Surgery In Women With Early Stage Cervical Cancer

Objective The aim of this article is to investigate the relative factors offertility preserving surgery in women with early stage cervical cancer.Methods133cases who have been performed surgery with I stage were studied usingretrospective analysis. Main relative factors include parametrial involvement,lymphovascular space invasion, lymph node metastases, ratio of invasion depth,tumor size, histological grade and clinical stage.Results①There was no parametrial involvements, lymphovascular spaceinvasions in women with Ia1stage.②There was no lymphovascular space invasionsand lymph node metastases in women with Ia2stage.③In88women with Ib1stage,there was10parametrial involvements (11.4%)，19lymphovascular space invasions(21.6%),11lymph node metastases (12.5%).④In12women with Ib2stage, therewas1parametrial involvement (8.3%),2lymphovascular space invasions (16.7%),1lymph node metastases (8.3%).⑤The rate of metastases is higher in women whoseratio of invasion depth is more than1/2.⑥The rate of parametrial involvementsand lymph node metastases are higher in women whose ratio of invasion depth ismore than2/3.⑦Ratio of invasion depth does not related with lymphovascularspace invasions. Tumor size does not related to metastases.Conclusion In patients with Ia1stage, when there is no lymphovascular spaceinvasion, a fertility preserving surgery with cervical conization is suggested.When there is lymphovascular space invasion in women with Ia1stage, afertility-sparing surgery consisting of radical trachelectomy with pelviclymphadenectomy is considerable. In patients with Ia2stage, when there is nolymphovascular space invasion, a fertility preserving surgery consisting of radical trachelectomy with pelvic lymphadenectomy is suggested. As to women withIb1stage, when there is no lymphovascular space invasion, the ratio of invasiondepth is less than1/2as well as the tumor size is less than2cm, radicaltrachelectomy with laparoscopic pelvic lymph node dissection is feasible.
