Lobectomia assistida por robô vs. lobectomia assistida por vídeo para NSCLC (RAVAR) (RAVAR)

4 de outubro de 2026 atualizado por: Hao-Xian Yang, Sun Yat-sen University

Lobectomia assistida por robô versus lobectomia assistida por vídeo para câncer de pulmão de células não pequenas (RAVAR): um ensaio multicêntrico, aberto, randomizado e de não inferioridade

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.
