The combination of new immunotherapy and radiotherapy: A new potential treatment for locally advanced non-small cell lung cancer. Curr Clin Pharmacol. 2016 Dec 01; Authors: Sacco PC, Maione P, Guida C, Gridelli C Abstract Lung cancer is the main reason of cancer death worldwide. About 30% of non-small-cell lung cancer (NSCLC) cases are diagnosed with locally advanced disease (stage III). This is a mixed population including patients who have far more extensive and bulky disease than others. Management of these patients continue to be a challenge; frequently, patients have both local recurrence and distant metastases in this stage and the prognosis is very poor with a 5-year overall survival estimated between 3% and 7% for inoperable disease. The standard treatment for these patients is concurrent chemo-radiotherapy (CRT) improving survival when compared to sequential combination as shown in several metanalysis. Recently, immune-therapies, including checkpoint inhibitor, such as monoclonal antibodies against programmed death receptor 1 (PD-1) and programmed death ligand 1 (PD-L1), have shown to enhance survival compared to chemotherapy in patients with advanced NSCLC. The integration of radiotherapy with immunotherapy is a conceptually promising strategy and several preclinical experiments have further developed the rationale for combining them. Radiotherapy has the capacity to overcome a lot of tumor immune escape mechanisms through ...
