Platinum-based two-drug chemotherapy is the first-line standard treatment for driver-negative advanced NSCLC, but most patients experience disease progression after 4 to 6 months. To extend the efficacy of first-line treatment, maintenance therapy is a logical clinical option for patients who are effective after 4 to 6 cycles of standard treatment. There is currently no standard regimen for maintenance treatment of NSCLC. We evaluated the effectiveness and safety of the anti-PD-1 monoclonal antibody (Toripalimab injection) followed by maintenance therapy in advanced NSCLC that was effective in the first-line standard regimen.Thereby improving the survival prognosis of advanced NSCLC.
Lung cancer is the malignant tumor with the highest incidence and mortality in China. Non-small cell lung cancer (NSCLC) ,which includes non-squamous cell carcinoma (including adenocarcinoma, large cell carcinoma, and other cell types) and squamous cell carcinoma, accounts for about 80% of lung cancer. Platinum-based two-drug chemotherapy is the first-line standard treatment for driver-gene negative advanced NSCLC, but most patients experience disease progression after 4 to 6 months. To extend the efficacy of first-line treatment, maintenance therapy is a logical clinical option for patients who are effective after 4 to 6 cycles of standard treatment. There is currently no standard regimen for maintenance treatment of NSCLC. We evaluated the effectiveness and safety of maintenance therapy with the anti-PD-1 monoclonal antibody (Toripalimab injection) followed by the first-line standard regimen in advanced NSCLC patients who are effective after standard treatment. With a view to exploring treatment methods that are effective for the maintenance treatment of driver-gene negative advanced NSCLC and have little toxic and side effects,thereby improving the survival prognosis of these patients.
