The Presence of Periodontal Pathogens in Gastric Cancer

Background and objectiveMicrobiota are thought to play a role in the development of gastric cancer (GC). Several studies have put forward putatively carcinogenic species in addition to Helicobacter pylori but are not in perfect alignment, possibly due to variable parameters in the experiments. Meta-analyses on this subject have not been published so far. Therefore, there is a lack of clinical guidance beyond H. pylori eradication therapy.
