Pdf Summary

Surgery is the preferred treatment for early stages of lung cancer, but the success of the procedure depends on the complete resection of the tumor and careful examination of the lymph nodes. Incomplete resection, where residual disease remains, is associated with poor survival. However, the current definition of incomplete resection does not consider inadequate surgery, particularly in regards to lymph node assessment. This study aimed to compare the overall survival of complete resections, uncertain resections, and incomplete resections for patients with no evidence of spread of cancer to lymph nodes or distant organs. The study also aimed to identify predictors of survival for uncertain resection patients and propose a classification system to predict long-term survival. The researchers retrospectively analyzed lung cancer patients who underwent surgery between 2008 and 2018. Of the 1108 patients included in the study, 732 were classified as complete resections, 291 were uncertain resections, and 85 were incomplete resections. The study found substantial variation in survival among uncertain resection patients, leading to the proposal of three subgroups within the uncertain resection category. The researchers suggest that uncertain resection should be included in the TNM classification system and used routinely in practice. They also recommend closer follow-up for high-risk patients. The study highlights the need for improved lymph node assessment in surgical procedures for lung cancer to reduce recurrence and improve patient prognosis.
