ERCC1 and small cell lung carcinoma: Meta-analysis of three studies in SCLC (292 patients), also provided evidence of a trend towards increased response to platinum-containing chemotherapy in high ERCC1 expressing tumours (average RR = 1.14; 95% CI: 0.99–1.31, p = 0.08; I2 = 0%), although this was not statistically significant.
