Abstract:

Perineural invasion in early-stage cervical cancer，is a new risk factor for the prognosis of cervical cancer.There may be a certain potential risk in retaining nerves and this is the reason why nerve-sparing radical hysterectomy（NSRH） is an important hot topic in clinical research at present.The aim to study PNI in cervical cancer is to develop clear indications for NSRH，in order to show the advantage of this surgical technique.PNI is one of the main factors affecting NSRH indications.Therefore，it is necessary to clarify the indications for NSRH，and it is imperative.

Key words: cervix tumor, nerve-sparing radical hysterectomy, perineural invasion

摘要：

早期宫颈癌可能存在嗜神经侵袭（PNI）现象，PNI是影响宫颈癌预后的新的高危因素，保留神经可能有一定的潜在风险。这也是目前有关保留神经术式争议的焦点之一。研究宫颈癌PNI的目的在于完善宫颈癌保留神经手术（NSRH）的手术适应证，从而更好地体现该术式的优越性，并不是否定NSRH。PNI是影响NSRH适应证的主要因素之一，因此，明确NSRH的适应证很有必要而且是势在必行。
