A Rare Presentation of a Non-Asian Female With Metastatic Non-small-cell Lung Cancer Harboring L747P Mutation With Clinical Response to Multi-targeted Epigenetic and Inhibition.

Background: Activating mutations of the epidermal growth factor receptor (EGFR) gene have been utilized to predict the effectiveness of EGFR tyrosine kinase inhibitor (TKI) therapy. The most common EGFR mutations are exon 19 deletion and exon 21-point mutation, which are sensitive to EGFR TKI. However, rare/complex EGFR mutations still exist, data of which are scarce and controversial.

Polyphenols Modulating Effects of PD-L1/PD-1 Checkpoint and EMT-Mediated PD-L1 Overexpression in Breast Cancer.

Investigating dietary polyphenolic compounds as antitumor agents are rising due to the growing evidence of the close association between immunity and cancer.
