The key findings showed that in the chemotherapy group, the overall survival rate of SLFN11-positive patients (SLFN11 was considered positive when at least 5% of the tumor cells were stained) was significantly better (P=0.012), and SLFN11 expression was positively correlated with the luminal subtype marker GATA3 (p=0.027). Here, SLFN11 is linked to neoplasm.
