Abstract
Immune checkpoint inhibitors with chemotherapy have been shown to exhibit remarkable efficacy for advanced non-small-cell lung carcinoma and are under investigation as an induction therapy. However, the significance of preoperative therapy with pembrolizumab + chemotherapy for surgically resectable non-small-cell lung carcinoma still remains unclear. Here, we report a case of stage IIIB non-small-cell lung carcinoma that underwent salvage surgery after three cycles of pembrolizumab + carboplatin + nab-paclitaxel. Computed tomography revealed the remarkable decrease in tumor volume by 81%. A pathological examination showed that viable neoplastic cells were observed in <1% of the total tumorous lesion suggesting near pathological complete response. This case suggests that this regimen might be a good option as induction therapy for non-small-cell lung carcinoma.
