Lung Cancer Clinical Trials

Lung cancer is a malignant tumor with the highest incidence and mortality rate of cancer patients worldwide. Traditional treatments for lung cancer include surgery, radiotherapy and chemotherapy, etc. Although the growth and spread of the tumor can be controlled to a certain extent, the cure rate for patients with progressive stage is still low and the prognosis is poor. Neoadjuvant therapy intends to use chemotherapy, immunotherapy, and targeted therapy to reduce the size and load of the tumor before surgery, to improve the surgical resection rate and therapeutic effect. 1. Primary research objective: to explore the therapeutic efficacy of patients with different characteristics under different neoadjuvant therapeutic regimens. 2. Secondary objectives To investigate the strengths and weaknesses of different neoadjuvant regimens in real-world clinical practice, and to investigate the long-term outcomes of patients treated with different regimens.
