YAP1 and small cell lung carcinoma: Due to the low number of studies in the Asian population in our combined analysis, we found no relationship between YAP expression and OS of patients with SCLC in our univariate analysis, whereas YAP expression was significantly associated with short OS of patients with SCLC in our combined analysis with multivariate data in the Asian population, indicating that YAP can also be considered a predictor of poor survival of patients with SCLC.
