Neoadjuvant nivolumab plus chemotherapy followed by resection for superior sulcus tumour with high PD-L1 expression:...

The standard treatment for resectable non-small cell lung cancer (NSCLC) located in the superior sulcus is neoadjuvant chemoradiotherapy followed by highly invasive resection. Based on the results of the CheckMate 816 trial, which showed a marked improvement in the efficacy of neoadjuvant chemo-immunotherapy, we report a case of minimally invasive resection after neoadjuvant nivolumab plus chemotherapy for superior sulcus NSCLC, resulting in a pathologic complete response. The patient was a 76-year-old man with a 65-mm right superior sulcus tumour diagnosed as squamous cell carcinoma with 95% PD-L1. After two courses of neoadjuvant nivolumab plus chemotherapy, the tumour was completely resected through an 11-cm right lateral thoracotomy with second rib resection and first rib preservation. No residual tumour cells were observed in the specimen, and the patient had a pathologic complete response. This report represents a new treatment option for superior sulcus tumours.
