abstract
Concurrent chemotherapy and radiation therapy remains the standard-of-care treatment in patients with unresectable stage III non-small-cell lung cancer. Most regimens include low doses of radiosensitizing agents. Because of concern for the presence of micrometastatic disease and the high rate of systemic failure, many trials have addressed the role of additional consolidation chemotherapy. Only a few of these studies have been performed in a randomized setting on a large number of patients, and the rest are smaller phase I and phase II trials that explore the safety and efficacy of different chemotherapy regimens. More recently, targeted agents have also been evaluated in such regimens, although molecular and histologic markers have not been fully incorporated in these studies. In this review, we discuss these trials and compare the different sequences and regimens of systemic doses of chemotherapy when delivered in addition to concurrent chemotherapy and radiation therapy.
