High YAP expression was significantly associated with short OS of patients with SCLC in our combined multivariate analysis in the Asian population (Ph = 0.289, I2 = 11.10%, crude HR = 4.482, 95% CI = 2.182–9.209), but not with the crude data (Ph = 0.033, I2 = 78.00%, crude HR = 1.654, 95% CI = 0.434–6.300) (Figure 3; Table 3). This evidence concerns the gene YAP1 and small cell lung carcinoma.
