Objective: Whether cycle number influences the subsequent pathological or surgical outcomes remained unclear. This study aimed to assess the efficacy and surgical safety of neoadjuvant immunochemotherapy‐based treatment in the real‐world setting. Methods: Clinical data of patients who received neoadjuvant immunochemotherapy for non‐small‐cell lung cancer between 2018 and 2021 were collected. Oncological outcomes such as objective response rate (ORR), major pathological response (MPR), and pathological complete response (pCR), and surgical outcomes including operating time, intraoperative bleeding, postoperative drainage, and hospital stay were analyzed. Results: In total, 176 patients were included, among whom 102 cases were lung squamous carcinoma (LUSQ). After immunochemotherapy, 98 (56%) of patients achieved ORR. Notably, the ORR (63% vs. 46%, p = 0.039) and pCR (45% vs. 27%, p = 0.022) were significantly higher in patients with LUSQ. For patients who received two, three, four, and five or more cycles, the ORRs were 52%, 67%, 53%, and 50% (p = 0.36). In post hoc analysis, cycle numbers showed no significant association with MPR or pCR (p = 0.14 and p = 0.073). Treatment cycles showed no influence on operating time, postoperative drainage, and hospital stay (p = 0.79, 0.37, and 0.22). Notably, the blood loss index of patients who received more than four cycles was higher than those receiving four or fewer cycles (mean blood loss: two or fewer cycles 153.1, three cycles 113.8, four cycles 137.6, and five or more cycles 293.3, respectively). Conclusions: This study indicated that cycles of neoadjuvant immunochemotherapy had no significant effect on the feasibility and safety of surgery. Although not statistically significant, patients who received five or more cycles of treatment experienced higher intraoperative blood loss. [ABSTRACT FROM AUTHOR]
