Abstract
Objective: In 2012, we proposed and described a modified triple incision technique (MTIT) for vulvar cancer patients with locally advanced disease. The MTIT has undergone a series of modifications, and a modified MTIT (M-MTIT) has been developed. The purpose of this study was to introduce the M-MTIT and compare it with the MTIT.
Study design: This was a retrospective cohort study. Fifty-seven vulvar cancer patients with clinical stage T2 (≥ 4 cm) or T3 disease were included. Of these patients, 28 underwent the MTIT and 29 underwent the M-MTIT. Data on surgery-related complications and survival outcomes were compared.
Results: Patients who were treated with the M-MTIT developed significantly less surgery-related morbidities than patients treated with the MTIT (24.1% vs. 60.7%, P = 0.005). Wound breakdown was the most common complication in our cohort, which occurred less frequently in the M-MTIT group than in the MTIT group (10.3% vs. 35.7%, P = 0.022). Multivariate logistic regression analysis identified the M-MTIT as an independent predictor of a reduced risk of wound breakdown. The incidence of other complications, including lymphedema, wound infection and cellulitis, was lower in the M-MTIT group than in the MTIT group; however, the differences did not reach statistical significance. The median follow-up time of this study was 33 months. Kaplan-Meier survival graphs did not show significant differences in recurrence-free survival or overall survival between the two groups.
Conclusions: The M-MTIT correlates with lower morbidity rates than the MTIT and does not compromise oncological safety. The M-MTIT can be considered a safe and feasible option for vulvar cancer patients with locally advanced disease.
