According to the Kaplan-Meier analysis, high expression of PLCγ1 or its activated forms was significantly correlated with lower DFS rates in patients with Luminal-A tumours (Fig. 1), but not in patients with Luminal-B tumours (Fig. 3), or HER2 positive (Additional file 2: Figure S3) or Triple Negative tumours (Additional file 2: Figure S4). This evidence concerns the gene PLCG1 and neoplasm.
