Non-small cell lung cancer (NSCLC) is the leading cause of cancer-related death worldwide. The 5-year overall survival (OS) rates for patients with pathological stage IA1/IA2/IA3/IB early-stage lung cancer are 90%, 85%, 80%, and 73%, respectively.
In the perioperative period, adequate postoperative analgesia is necessary for both functional recovery and patient comfort. Epidural anesthesia (EDA) is recommended in the ERAS protocol for open colorectal resection, based on its provision of …
Because pulmonary lobectomy with lymph node dissection provides better local control and an improved survival, it is the gold standard for any primary non-small cell lung cancer (NSCLC) [ 1 – 3 ]. However, a variety of complications can occur after …
