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) stage Ⅰ b2, Ⅱ a2 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 stage Ⅰb2 and 44 (24.9%) had Ⅱa2 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 Ⅰ b2, Ⅱ a2 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.
