The Role of Sublobar Resection in Early-Stage Non-Small-Cell Lung Cancer

Le résumé fourni par la source

The results of a prospective, multi-institutional randomized trial developed to assess the equality of sublobar resection versus standard lobectomy were first published in 1995. They concluded that, compared with lobectomy, sublobar resections did not show any significant improvement either in terms of postoperative morbidity and mortality nor in terms of late post-resectional cardiorespiratory function. Moreover, due to the higher mortality and local recurrence rate related to sublobar resection, lobectomy had to be judged as the best surgical option for patients diagnosed with peripheral early-stage non-small-cell lung cancer. Since then, lobectomy has been considered the best surgical option for fit patients suffering from early-stage non-small cell lung cancer. In 2022 and 2023, three non-inferiority randomized trials were published, comparing lobectomy with the sublobar resection in T1a N0 patients whose tumors were up to 2 cm in size. Although presenting some important differences, all three trials met their primary endpoints, disclosing the non-inferiority of sublobar resections in terms of overall and disease-free survival. This narrative review aims to compare the newly published results of these trials as well as to report results from recent non-randomized studies on this topic.
