Phase III Study Comparing Treatment Given Before and After Surgery Versus After Surgery Alone in Patients With Stage II to IIIB Resectable Non-Small Cell Lung Cancer

What this Trial Is About

Researchers are comparing two treatment approaches for patients with stage II-IIIB non-small cell lung cancer NSCLC that can be removed by surgery. The study evaluates whether giving standard therapy before and after surgery perioperative is better than giving it only after surgery adjuvant. This phase III trial focuses on chemotherapy and immunotherapy, which are current standard treatments aimed at controlling tumor growth and helping the immune system fight cancer. Patients are divided into two groups. One group undergoes surgery followed by chemotherapy and immunotherapy for up to one year if the disease does not progress or cause severe side effects. The other group receives chemotherapy combined with immunotherapy before surgery, then surgery, followed by immunotherapy alone for up to one year. Chemotherapy drugs may include cisplatin, carboplatin, pemetrexed, gemcitabine, docetaxel, or vinorelbine. Imaging tests like CT, MRI, or PETCT scans are done throughout the study. Participants will have surgery within a month of joining and receive treatments according to their assigned group. They will be monitored with scans and followed up every six months for up to 10 years to assess survival, disease progression, surgical outcomes, side effects, and immune responses. Researchers will measure event-free survival and overall survival as main results, as well as response rates and safety information over the long term.
