Oral organisms associated with respiratory tumors (lung cancer).

Subject	Organisms (Oral Bacteria)	Sample Type	Reference
Lung adenocarcinoma patients who did not smoke (cancer, n = 91) and healthy controls (control, n = 91).	The proportion of Eillonella was higher in the disease group than it was in the control group, while the proportions of Mogibacterium, Butyrivibrio, Variovorax, Ralstonia, Catonella, Bulleidia, and Oribacterium were lower.	saliva	[133]
Cases were subjects who were diagnosed with incident lung cancer (n = 114) and with controls (n = 114).	The proportions of Bacilli class and Lactobacillales order were higher in the disease group than they were in the control group, while the proportions of Spirochaetia and Bacteroidetes were lower.	mouth rinse samples	[134]
148 subjects with lung nodules from the NYU Lung Cancer Biomarker Center.	Oral bacteria such as Veillonella, Streptococcus, Prevotella, and Haemophilus were enriched in LC.	lower airway brushes	[136]
