Combining antiangiogenic therapy with neoadjuvant chemotherapy increases treatment efficacy in stage IIIA (N2) non-small cell lung cancer without increasing adverse effects.

ABSTRACT: To evaluate the safety and efficacy of combining Endostar antiangiogenic therapy with neoadjuvant chemotherapy for the treatment of stage IIIA (N2) NSCLC, we conducted a randomized, controlled, open-label clinical study of 30 NSCLC patients. Patients were randomly assigned to the test or control groups, which received either two cycles of an NP neoadjuvant chemotherapy regimen combined with Endostar or the NP regimen alone, respectively, at a 2:1 ratio. Efficacy was assessed after 3 weeks, and surgical resection occurred within 4 weeks, in the 26 patients who successfully completed treatment. While total response rates (RR) and clinical benefit rates (CBR) did not differ between the experimental groups, total tumor regression rates (TRR) were higher in the test group than in the control group. Median DFS and OS also did not differ between the test and control groups. Clinical perioperative indicators, including intraoperative blood loss, number of dissected lymph node groups, duration of postoperative indwelling catheter use, and time to postoperative discharge, were comparable in the test and control groups. Finally, hematological and non-hematological toxicities and postoperative pathological indicators, including down-staging ratio, complete resection ratio, and metastatic lymph node ratio, also did not differ between the groups. Overall, combining Endostar with NP neoadjuvant chemotherapy increased therapeutic efficacy without increasing adverse effects in stage IIIA-N2 NSCLC patients. This study is registered with ClinicalTrials.gov (number NCT02497118).

Project description:BackgroundWe sought to determine the perioperative safety and feasibility outcomes of stage IIIA (N2) non-small cell lung cancer (NSCLC) following neoadjuvant immunotherapy or neoadjuvant chemotherapy.MethodsThe clinical details of patients who attended the Affiliated Hospital of Qingdao University between January 2019 and December 2020 were retrospectively evaluated. Eligible patients had pathologically proven stage IIIA (N2) NSCLC and were randomly prescribed neoadjuvant therapy. Those in the neoadjuvant immunotherapy group received two cycles of nivolumab (3 mg/kg) and those in the control group received neoadjuvant chemotherapy (1,000 mg/m2 gemcitabine and 80 mg/m2 cisplatin). All patients were scheduled to undergo surgery. The primary endpoint was the risk of major complications within 30 days of surgery and the secondary endpoints were interval to surgery and 30-day mortality.ResultsA total of 107 eligible patients were evaluated of whom 25 were allocated to the neoadjuvant immunotherapy group and 82 to the neoadjuvant chemotherapy group. The median interval to surgery was similar in the two groups at 29.2 days [95% confidence interval (CI), 27.1 to 31.4 days] in the immunotherapy group and 28.7 days (95% CI, 27.6 to 29.8 days) in the chemotherapy group (P=0.656). While treatment-related adverse events were reported in most patients, all 25 patients completed two cycles of neoadjuvant immunotherapy and 80 of 82 patients completed two cycles of neoadjuvant chemotherapy, although one patient in the latter group died within 30 days of surgery. There was no statistically significant difference between the groups in the probability of grade 3 or higher postoperative complications within 30 days after surgery (P=0.757).ConclusionsMost patients achieved the primary and secondary endpoints of the study. However, the major pathological response (MPR) showed statistically significant differences between the neoadjuvant immunotherapy and neoadjuvant chemotherapy groups.
