Abstract:
Objective To explore the effects and postoperative prognostic factors in cervical cancer patients received neoadjuvant chemotherapy combined with surgery and post-operative adjuvant therapy. Methods A total of 177 patients with cervical cancer at International Federation of Gynecology and Obstetrics (FIGO) stageⅠb2, Ⅱa2 who underwent neoadjuvant chemotherapy (NACT) followed by surgery with and without adjuvant therapy in Cancer Hospital, Chinese Academy of Medical Sciences were included. Univariate and multivariate analyses of 5-year overall survival (OS) rate and 5-year disease-free survival (DFS) rate were performed. Results Of 177 patients, 133 (75.1%) had stageⅠb2 and 44 (24.9%) hadⅡa2 cancers. After NACT,overall response rate was 63.3% (112/177) including 12 cases of complete response (CR), 100 of partial response (PR) and no progressive disease (PD) case. At a median follow-up of 59.2 months, the 5-year DFS rate was 73.6% and the 5-year OS rate was 86.8%. Univariate analysis revealed that lymph node metastasis, deep stromal invasion and tumor size after NACT significantly affected 5-year DFS rate (P<0.05). Lymph node metastasis, deep stromal invasion and tumor size after NACT significantly affected 5-year OS rate (P<0.05). The multivariate analysis showed that, stromal invasion (outer 1/3 or outer 1/2) was independent risk factor of 5-year DFS rate (P<0.05), and 5-year OS rate was significantly affected by tumor size >3 cm after NACT (P<0.05). Conclusions The effect of NACT in Ⅰb2, Ⅱa2 squamous carcinoma of the uterined cervix is confirmed. The independent risk factor for 5-year DFS rate in patients received NACT and hysterectomy is deep stromal invasion of the cervix. The presence of tumor size>3 cm after NACT adversely affect 5-year OS rate.
