Objective: To explore the relationship between laparoscopic radical hysterectomy (LRH) and cervical cancer lymph-vascular space invasion (LVSI) by comparing the prevalence of LVSI in cervical cancer patients who underwent LRH versus open radical hysterectomy (ORH).
Methods: The study participants were 1087 cervical cancer patients (FIGO 2009 stages IA2-IIA2) with pathologically confirmed with or without LVSI who underwent radical hysterectomy at Shengjing Hospital of China Medical University from 2013 through 2018. The patients were divided according to the type of surgical procedure into an LRH group (n=148) and an ORH group (n=939).
Results: In the LRH group, 31.76% of patients (47/148) had LVSI-positive tumors compared to 33.23% of patients (312/939) in the ORH group; the difference was not significant (p=0.724). No between-group differences in LVSI prevalence according to lymph node metastasis, interstitial infiltration depth, differentiation degree, and parametrial infiltration were found. However, the number of LVSI-positive patients whose cervical cancer lesions > 4 cm (stage I B2 and II A2) was significantly higher in the LRH group than in the ORH group (Odds Ratio [OR] 0.333, 95% confidence interval [CI] 0.157– 0.706, p=0.005). The 3-Year disease-free survival (DFS) in the LRH group is lower than that in the ORH group (94.75% vs 97.27%), but there was no significance (P=0.187). Furthermore, the percentage of LVSI-positive tumors in patients with lymph node metastases was significantly higher than those without lymph node metastases (OR 2.897, 95% CI 2.129– 3.942, p=0.000). The 3-Year DFS were 98.22% in the LVSI negative patients and 93.78% in the LVSI positive patients, the difference was significant (P=0.002).
Conclusion: A higher risk of lymph node metastasis and a lower 3-Year DFS was found in the LVSI-positive patients. In case of LVSI, it would be dangerous to treat patient in laparoscopy, especially in case of cervical cancer lesions > 4cm.
