Background: Thoracotomy, video-assisted thoracoscopic surgery (VATS) and robotic assisted thoracoscopic surgery (RATS)-lobectomy are widely accepted procedures for the surgical treatment of clinical (c)stage I non- small cell lung cancer (NSCLC). In the current literature which procedure gives more benefits is still debated. We present a comparison between these three procedures in term of advantages and postoperative outcomes.
Methods: A multicentric study about 259 lobectomies from 2013 to 2019: 128 patients underwent TL, 96 VATS and 35 RATS. Different variables were retrospectively analyzed among these three cohorts of patients with diagnosis of cStage I NSCLC.
Results: Rate of major complications comparable in VATS, RATS and TL; Advantages for RATS in minor complications (TL 34.4% vs. VATS 18.75% vs. RATS 8.57%. P=0.0015), postoperative days in Intensive Care Unit, days to chest tube removal, length of postoperative hospitalization (P<0.0001) and number of lymph nodes dissected (P=0.0257). Operating times are shorter in VATS than RATS (P<0.05). Pain (NRS Scale) is comparable.
Conclusions: TL remains the conventional approach for stage II-IIIA(N2) NSCLC. RATS showed great advantages, but its higher operating time and costs, mostly, today don't justify its adoption as gold standard for the surgical treatment of cStage I NSCLC, instead of VATS.
