Robotondersteunde versus video-geassisteerde lobectomie voor NSCLC (RAVAR) (RAVAR)

4 oktober 2026 bijgewerkt door: Hao-Xian Yang, Sun Yat-sen University

Robot-geassisteerde versus video-geassisteerde lobectomie voor niet-kleincellige longkanker (RAVAR): een multicenter, open-label, gerandomiseerde, non-inferioriteitsstudie

Video-assisted thoracic surgery (VATS) has been recommended by clinical guidelines as one of the preferred surgeries for early-stage non-small cell lung cancer (NSCLC) for many years. However, VATS has inherent drawbacks, so at the beginning of this century, robotic-assisted thoracoscopic surgery (RATS) was first applied for lung resection. In recent years, RATS has developed rapidly, but there are still many unsolved scientific problems in the field of RATS. Thus, a multicenter prospective randomized controlled trial was conducted with stage I-II NSCLC patients as the study subject and 5-year DFS as the primary endpoint to compare the short-term and long-term outcomes of RATS and VATS in the treatment of early-stage NSCLC.
