A recent study revealed that the NLR could differentiate between two histological groups of gastric cancers (differentiated [tubular adenocarcinoma well-differentiated type, tubular adenocarcinoma moderately differentiated type, and papillary adenocarcinoma] vs. undifferentiated [poorly differentiated adenocarcinoma solid type, poorly differentiated adenocarcinoma solid type, and SRC]) [22]. This evidence concerns the gene SRC and gastric tubular adenocarcinoma.
