A Phase III Randomized Trial of Adjuvant Chemotherapy With or Without Bevacizumab for Patients With Completely Resected Stage IB (≥ 4 cm) - IIIA Non-small Cell Lung Cancer (NSCLC)

This randomized phase III trial studies chemotherapy and bevacizumab to see how well they work compared to chemotherapy alone in treating patients with stage IB, stage II, or stage IIIA non-small cell lung cancer that was removed by surgery. Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving more than one drug (combination chemotherapy) may kill more tumor cells. Monoclonal antibodies, such as bevacizumab, may interfere with the ability of tumor cells to grow and spread. Bevacizumab also may stop the growth of non-small cell lung cancer by blocking the growth of new blood vessels necessary for tumor growth. It is not yet known whether chemotherapy is more effective with or without bevacizumab in treating non-small cell lung cancer.
