Multi-modality treatment of non-small cell lung cancer

Despite significant advances in radiation therapy techniques and a variety of newer chemotherapeutic agents, when multimodality treatment for stage I and II tumors has been tested by Phase III randomized prospective trials of adequate size, no significant survival advantage over surgery alone has been found in most instances. Modalities tested include preoperative radiation therapy, and postoperative chemotherapy and radiation therapy. Trials are presently underway to test preoperative chemotherapy for stages Ib, II, and T3NI (S9900) and to test adding surgery for patients with N2 disease who have been treated by chemotherapy and radiation therapy (INT 0139). Results of a recently completed trial (JBR10) will answer the question of whether postoperative chemotherapy is of benefit for patients with stages T2N0 or T1-2N1. Until these trials are completed, surgeons should resist the temptation to use newer but unproven therapies except within established approved protocols.
