TL;DR: The natural course of oral lichen lesions among unselected, non-consulting individuals appears to be benign in the great majority, and the cohort size does not permit firm conclusions regarding oral cancer risk.

TL;DR: Serological evidence of antibodies to cytotoxin-associated gene A (CagA) antigens may exist without concomitant Helicobacter pylori IgG enzyme linked immunosorbent assay (ELISA) seropositivity, but unless the histology is often restituted after spontaneous disappearance of the infection, atrophy does not appear to be a mandatory intermediate step leading to this serology.

TL;DR: Evidence supporting the null association between H. pylori infection and pancreatic cancer risk in western European populations is provided, however, the suggested association between chronic corpus atrophic gastritis and pancreati cancer risk warrants independent verification in future studies, and, if confirmed, further studies on the underlying mechanisms.

TL;DR: Based on a population-based study, the association between BMI and EAC does not appear to be affected by symptomatic gastroesophageal reflux, although there appears to be synergyBetween BMI and reflux.

TL;DR: It is suggested that BPH overall is not associated with bladder cancer risk, however, among men treated with TURP, particularly those with other comorbid GU tract conditions, risk of bladder cancer was elevated.
