Objective: To investigate the factors affecting the prognosis of stage â
a2-â
¡a2 cervical cancer after laparoscopic radical hysterectomy (LRH), and to compare the prognosis and recurrence sites of patients with different colpotomy paths. Methods: The clinical data of 965 patients with stage â
a2-â
¡a2 cervical cancer who underwent LRH in the First Affiliated Hospital of Army Medical University from January 2015 to December 2018 were collected. The median age was 47.0 years of all patients with a median follow-up of 62 months (48-74 months). Cox regression was used to perform the univariate and multivariate analysis of the clinicopathological factors associated with the prognosis that included disease-free survival (DFS) and overall survival (OS). Patients were categorized into LRH through vaginal colpotomy (VC group, n=475) and LRH through intracorporeal colpotomy (IC group, n=490) according to the colpotomic approaches. The prognosis and recurrence sites of patients in each group were compared. Results: (1) During the follow-up period, 137 cases recurred (14.2%, 137/965) and 98 cases died (10.2%, 98/965). The 5-year DFS and OS were 85.8% and 89.9%, respectively. In univariate analysis, positive vaginal margin (PVM) was significantly affected the 5-year OS of patients with cervical cancer (P=0.023), while clinical stage, maximum diameter of tumor, degree of pathological differentiation, lymph node metastasis (LNM), depth of cervical stromal invasion, parametrium involvement, and uterine corpus invasion (UCI) were significantly associated with 5-year DFS and OS in patients with cervical cancer (all P<0.05). In multivariate analysis, clinical stage (HR=1.882, 95%CI: 1.305-2.716), LNM (HR=2.178, 95%CI: 1.483-3.200) and UCI (HR=3.650, 95%CI: 1.906-6.988) were independent risk factors of 5-year DFS (all P<0.001). Clinical stage (HR=2.500, 95%CI: 1.580-3.956), LNM (HR=2.053, 95%CI: 1.309-3.218), UCI (HR=3.984, 95%CI: 1.917-8.280), PVM (HR=3.235, 95%CI: 1.021-10.244) were independent risk factors of 5-year OS (all P<0.05). (2) Different colpotomy paths did not significantly affect the 5-year DFS and OS of patients with stage â
a2-â
¡a2 cervical cancer. The 5-year DFS in VC group and IC group were 85.9% and 85.6% (P=0.794), and the 5-year OS were 90.8% and 89.3% (P=0.966), respectively. Recurrence patterns consisted of intraperitoneal recurrence, pelvic recurrence, vaginal stump recurrence, and lymph node and distant metastasis. The intraperitoneal recurrence rate of VC group was significantly lower than that of IC group [0.6%(3/468) vs 2.3% (11/485), P=0.037], while the rates of pelvic recurrence, vaginal stump recurrence, lymph node and distant metastasis and overall recurrence were not significantly different between two groups (all P>0.05). Subgroup analysis of patients with different clinical stages, LNM and UCI showed that statistical differences of the intraperitoneal recurrence rates between two groups were only in patients without LNM (0.5% vs 2.3%, P=0.030) or without UCI (0.7% vs 2.3%, P=0.037). Conclusions: Clinical stage, LNM, PVM and UCI are independent risk factors for the prognosis of patients with stage â
a2-â
¡a2 cervical cancer. For patients without LNM or UCI, LRH through VC could reduce the intraperitoneal recurrence rate, while it is not enough to improve 5-year DFS and OS of patients. Low proportion of intraperitoneal recurrence, intra-operative tumor cells spillage to vagina stump and pelvic cavity might be the explanation.
