Importance of XRT in SCLCChemotherapy vs Chemotherapy + RT
• JP Pignon, et al. NEJM. 327:1618-1624, 1992. - meta-analysis– 2,103 pt with limited stage SCLC from 13 randomized trials comparing chemo
alone to chemo + RT– end-point: survival– RR of death with addition of RT = 0.86– administration of thoracic RT produced a 14% reduction in the mortality rate– conclusions :
• (1) limited stage SCLC, addition of thoracic RT produced a 14% reduction in mortality rate, corresponding to a 5% greater 3-yr survival
