摘要

Background Increased detection of small-sized, peripheral, non-small-cell lung cancer has renewed interest in sublobar resection instead of lobectomy, the traditional standard of care for early-stage lung cancer. We aimed to assess morbidity and mortality associated with lobar and sublobar resection for early-stage lung cancer. Methods CALGB/Alliance 140503 is a multicentre, international, non-inferiority, phase 3 trial in patients with peripheral non-small-cell lung cancer clinically staged as T1aN0. Patients were recruited from 69 academic and community-based institutions in Australia, Canada, and the USA. Patients were randomly assigned intraoperatively to either lobar or sublobar resection. The random assignment was based on permuted block randomisation without concealment and was stratified according to radiographic tumour size, histology, and smoking status. The primary endpoint of the trial is disease-free survival; here, we report a post-hoc, exploratory, comparative analysis of perioperative mortality and morbidity associated with lobar and sublobar resection. Perioperative mortality was defined as death from any cause within 30 days and 90 days of surgical intervention and was calculated for all randomised patients. Morbidity was graded using Common Terminology Criteria for Adverse Events version 4.0. All analyses were done on an intention-to-treat basis for randomised patients with data available. This trial is registered with ClinicalTrials.gov, number NCT00499330. Findings Between June 15, 2007, and March 13, 2017, 697 patients were randomly allocated to either lobar resection (n=357) or sublobar resection (n=340; 59% wedge resection). Six (0·9%) patients died by 30 days, four (1·1%) after lobar resection and two (0·6%) after sublobar resection; by 90 days, ten (1·4%) patients had died, six (1·7%) after lobar resection and four (1·2%) after sublobar resection (difference at 30 days, 0·5%, 95% CI −1·1 to 2·3; difference at 90 days, 0·5%, 95% CI −1·5 to 2·6). An adverse event of any grade occurred in 193 (54%) of 355 patients after lobar resection and 172 (51%) of 337 patients after sublobar resection. Adverse events of grade 3 or worse occurred in 54 (15%) patients assigned lobar resection and in 48 (14%) patients assigned sublobar resection. No differences between surgical approaches were noted in cardiac or pulmonary complications. Grade 3 haemorrhage (requiring transfusion) occurred in six (2%) patients assigned lobar resection and eight (2%) patients assigned sublobar resection. Prolonged air leak occurred in nine (3%) patients after lobar resection and two (1%) patients after sublobar resection. Interpretation Our post-hoc analysis showed that perioperative mortality and morbidity did not seem to differ between lobar and sublobar resection in physically and functionally fit patients with clinical T1aN0 non-small-cell lung cancer. These data may affect the daily choices made by patients and their doctors in establishing the best treatment approach for stage I lung cancer. Funding National Cancer Institute.
