Efficacy evaluation of vaginal-assisted laparoscopic radical hysterectomy and laparoscopic radical hysterectomy for cervical cancer: a single-center retrospective case series study

Background: To investigate the survival outcomes of abdominal radical hysterectomy (ARH), laparoscopic radical hysterectomy (LRH), and vaginal-assisted laparoscopic radical hysterectomy (VALRH) in the treatment of cervical cancer patients. Methods: This was a retrospective study. We collected the clinical data of 654 patients with cervical cancer (406 ARH, 172 LRH, and 76 VALRH), then compared the effects of different surgical methods on recurrence and survival. Results: Total overall survival (OS) were no significant differences in three groups (P>0.05). Total disease-free survival (DFS) was significantly higher in ARH group than in LRH group [hazard ratio (HR) =2.8, 95% confidence interval (CI): 1.199-3.607, P=0.004]; however, there were no significant differences between the VALRH (94.7%) and ARH (93.3%) groups. Subgroup stratification analysis showed that the overall recurrence rate in LRH group was significantly higher than that of the ARH groups for patients with a tumor size from >= 2 to <4 cm, negative postoperative lymph nodes, and no postoperative adjuvant therapy (all P<0.05). However, in the subgroup with tumor sizes of >= 2, <4, and >= 4 cm, no matter whether the lymph nodes were positive or not, and those with no postoperative supplementary adjuvant therapy, LRH was associated with a significantly higher local pelvic recurrence rate than ARH (all P<0.05). No significant differences between VALRH and ARH in any of the subgroup analyses (all P>0.05). A Cox analysis indicated that LRH increased the risk of overall and local pelvic recurrence after surgery compared with ARH (HR =2.338, 95% CI: 1.186-4.661, P=0.014; HR =10.313, 95% CI: 2.839-37.460, P<0.001); however, no significant difference between VALRH and ARH (all P>0.05). Sensitivity analysis of surgeons did not change the conclusions. Conclusions: Our analyses showed that the local pelvic recurrence rates and overall recurrence rates of LRH were significantly higher than ARH. VALRH could avoid tumor intraperitoneal exposure and achieve the same tumor prognosis as open surgery. By improving the standardization of minimally invasive surgery for early cervical cancer and paying close attention to the tumor-free concept, minimally invasive radical hysterectomy may achieve the same tumor outcome as open surgery.
