With the popularity of neoadjuvant therapy as first-line treatment, especially for advanced squamous cell carcinoma (SCC), the focus has become accurate individualized treatment. Specifically, toxic side effects of traditional platinum-doublet chemotherapy are high, so treatment with pembrolizumab plus platinum-doublet chemotherapy is safer and more effective. Pembrolizumab is a humanized monoclonal IgG4 kappa anti-PD1 antibody. It is devoid of any cytotoxic activity among the drug effect. Pembrolizumab has been tested clinically in a series of KEYNOTE studies and 12 categories of malignancies have been tested to determine their clinical effects. A 64-year-old man with IIIA SCC of the lung without any surgical contraindications in the preoperative period successfully underwent radical resection and had a great prognosis after neoadjuvant treatment. Chest computed tomography (CT) showed that the left upper lung lesion, hilar and mediastinal lymph nodes were obviously smaller than before, meanwhile, obstructive pneumonia was significantly absorbed. No sign of metastasis was detected by head-abdominopelvic CT and bone scan. Although radiation pneumonitis was an adverse event after postoperative adjuvant therapy, symptoms were relieved with low-dose glucocorticoids. In conclusion, traditional chemotherapy with single agents alone has been gradually replaced by pembrolizumab plus platinum-doublet chemotherapy as a first-line therapy now.
