Abstract
Lung cancer has the highest morbidity and mortality worldwide among the malignant tumors. The treatment of lung cancer was difficult in the decade years. Currently, the advent of immune checkpoint inhibitors (ICIs) has changed the pattern of lung cancer treatment. Programmed death-ligand 1 (PD-L1) inhibitors, such as pembrolizumab, plus platinum-based chemotherapy is the preferred treatment modality for advanced or metastatic non-small cell lung cancer (NSCLC) patients. The success of pembrolizumab in lung cancer has increased interest in expanding the use of neoadjuvant treatment. Immune-related adverse events (irAEs) are the most common adverse reactions in immunotherapy. The balance between the benefits and risks is crucial in this setting. Video-assisted thoracoscopic surgery (VATS) is a routine procedure of resectable NSCLC treatment. It appears to favor low postoperative complication rate. The prolonged air leakage (PAL) is the most common complication after VATS, and the bronchopleural fistula (BPF) is the most serious complication. The management of adverse events after VATS, especially in the setting of immune therapy, need to be raised. Here, we report a case of BPF following VATS lobectomy, which firstly presented the treatment-related adverse event with neoadjuvant combination therapy of pembrolizumab plus cisplatin/pemetrexed. Literature on novel neoadjuvant immunotherapy was also reviewed in the present study.
