Combination of radiotherapy and chemotherapy in locally advanced NSCLC

The combination of radiotherapy and chemotherapy is considered to be a standard approach for patients with locally advanced, stage III non-small-cell lung cancer. The current state of the art of combined radiochemotherapy supported by evidence-based data is presented. As shown in the meta-analyses, the concurrent radiochemotherapy gives a superior outcome in terms of survival compared with sequential delivery of both modalities. This is obtained at the expense of higher toxicity, which makes further intensification of radiochemotherapy challenging. Eligibility of patients with non-small-cell lung cancer for such an approach is limited. The new methods to improve treatment results, such as selection of proper strategies, incorporation of molecular agents into combined treatment and radiotherapy technique modifications are discussed.
