Resumen

El tratamiento estándar del carcinoma no microcítico de pulmón (CNMP) localmente avanzado inoperable es la combinación de quimioterapia y radioterapia tanto de forma secuencial como concurrente. Para aumentar el control locorregional se utilizan radiosensibilizantes que son agentes quimioterápicos que potencian el efecto biológico de la radiación sobre las células tumorales a dosis menores de las usadas habitualmente. Este trabajo es una revisión de la literatura sobre los estudiosin vitro ein vivo de la combinación de gemcitabina con radioterapia, estudios de viabilidad, ensayos pilotos y ensayos fase I y II, en el CNMP localmente avanzado inoperable.

Abstract

The treatment of locally advanced non-resectable non-small cell lung cancer (NSCLC) is a combination of chemotherapy and radiotherapy; whether in sequence or concurrent. Radiation sensitising agents can be used to improve loco-regional control based on the ability of some chemotherapy drugs to enhance the effect of the radiotherapy on tumor cells, while using lower-than-usual doses. This is a review of the literature and of differentin vitro andin vivo studies that have used the combination of gemcitabine and radiotherapy. Also included are feasibility studies, pilot tests, and phase I and II trials in the treatment of non-resectable locally advanced NSCLC.
