Background: The combination of neoadjuvant chemotherapy and surgery in lung cancer therapy is well established. The role of uniportal video assisted thoracoscopy (VATS) is still not described in literature. This study presents the preliminary short-term results of uniportal VATS after neoadjuvant therapy in our series.
Methods: The prospectively collected data of 154 patients after uniportal VATS anatomical lung resection (18 patients after neoadjuvant chemotherapy and 136 surgeries alone) were retrospectively reviewed. The perioperative results and follow-up of patients after neoadjuvant therapy were analyzed and compared to those after surgery alone.
Results: The mean age of population was 67.51±10.63 years. The mean operative time was overlapping in both groups: 248.97±118.17 min in surgery group and 287.17±94.13 min in chemotherapy + surgery group (P=0.190), with no difference in terms of types of anatomical lung resections performed and number of lymph nodes retrieved. The intraoperative mortality was null in both groups. The incidence of all complications was the same in both groups and no correlations was found with any possible risk factor evaluated (age, gender, comorbidities, type of resection, histology, etc.). Among minor complications, the incidence of parenchymal fistula was significantly higher in the 18 patients underwent chemotherapy (22.2% vs. 5.1% respectively, P=0.013). The overall survival of the series was 93% at 1 year follow-up and 88% at 5-year. The 1- and 2-year survival in only surgery group was 94% and 89% respectively vs. 85% and 85% in Chemotherapy + surgery, without any significant difference (P=0.324).
Conclusions: According to our experience, uniportal VATS after neoadjuvant therapy is feasible and quite safe. The oncological results and postoperative complications are comparable to those of other techniques. Uniportal VATS can be performed even for complicated cases in experienced centers.
