Surgical Outcomes After Neoadjuvant Chemotherapy and Ipilimumab for Non-Small Cell Lung Cancer.
BACKGROUND: The objective of this study was to evaluate the safety and feasibility of using neoadjuvant chemotherapy plus ipilimumab followed by surgery as a treatment strategy for stage II-IIIA non-small cell lung cancer. METHODS: From 2013 to 2017, postoperative data from patients who underwent surgery after neoadjuvant chemotherapy plus ipilimumab in the TOP1201 trial, an open label phase II trial (NCT01820754), were prospectively collected. The surgical outcomes from TOP1201 were compared with outcomes in a historical cohort of patients receiving standard preoperative chemotherapy followed by surgery identified from our institution's prospectively collected thoracic surgery database. RESULTS: In the TOP1201 trial, 13 patients were treated with preoperative chemotherapy and ipilimumab followed by surgery. In the historical cohort, 42 patients received preoperative chemotherapy by a platinum doublet regimen preoperative chemotherapy by a platinum doublet regimen without ipilimumab followed by lobectomy or pneumonectomy. The 30-day mortality in both groups was 0%. The most frequently occurring perioperative complications in the TOP1201 group were prolonged air leak (n = 2, 15%) and urinary tract infection (n = 2, 15%). The most common perioperative complication in the preoperative chemotherapy alone group was atrial fibrillation (n = 6, 14%). One patient (8%) had atrial fibrillation in the TOP1201 group. There was no apparent increased occurrence of adverse surgical outcomes for patients in the TOP1201 group compared with patients receiving standard of care neoadjuvant chemotherapy alone before surgery for stage II-IIIA non-small cell lung cancer. CONCLUSIONS: This report is the first to demonstrate the safety and feasibility of surgical resection after treatment with ipilimumab and chemotherapy in stage II-IIIA non-small-cell lung cancer.
