宫颈癌患者卵巢转移与保留问题的探讨

Ovarian Metastasis and Ovarian Preservation in Cervical Cancer Patients

宫颈癌的卵巢转移率与病期及组织学类型有关。易发生卵巢转移的高危因素有 :子宫颈管深肌层、宫体、宫旁组织受侵犯 ,淋巴管或血管浸润及盆腔淋巴结转移。早期宫颈癌尤其是鳞癌的卵巢转移率较低 ,如不存在高危因素 ,对绝经前患者可考虑保留卵巢。宫颈癌根治术中保留卵巢的方法有 :卵巢原位保留、卵巢移位、卵巢移植、卵巢埋藏和卵巢皮质移植。卵巢移位术是保留卵巢最常用的方法。

The incidence of ovarian metastasis in cervical cancer patients is related to stage and pathological type. The risk factors for ovarian metastasis are the invasion of the deeper cervical stroma, uterine corpus and parametrial tissues, infiltration of lymphovascular vessels, and pelvic lymph node metastasis. The incidence of ovarian metastasis in early cervical cancer is low, so the ovaries can be preserved in premenopause patients without risk factors. The ovary can be conserved in radical hysterectomy for cervical cancer by ovarian conservation in situ, ovarian transposition, ovarian transplantation, ovarian embedding and ovarian cortical transplantation. Ovarian transposition is the most common method. The function of transposed ovary is closely related to the distance between the preserved ovary and the radiation field edge.
