Helicobacter pylori (Hp) is the major recognized risk factor for non-cardia gastric cancer (GC), but only a fraction of infected subjects develop GC, thus GC risk might reflect other genetic/environmental cofactors and/or differences in virulence among infectious Hp strains. Focusing on a high GC risk area of Northern Italy (Cremona, Lombardy) and using archived paraffin-embedded biopsies, we investigated the associations between the Hp vacA and cagA genotype variants and gastric intraepithelial neoplasia (GIN, 33 cases) versus non-neoplastic gastroduodenal lesions (NNGDLs, 37 cases). The glmM gene and the cagA and vacA (s and m) genotypes were determined by polymerase chain reaction (PCR) and sequencing. Hp was confirmed in 37/37 (100%) NNGDLs and detected in 9/33 GINs (27%), consistently with the well-known Hp loss in GC. CagA was detected in 4/9 Hp-positive GINs and in 29/37 NNGDLs. The vacA s1a and m1 subtypes were more common in GINs than in NNGDLs (6/7 vs. 12/34, p=0.014, for s1a; 7/7 vs. 18/34, p=0.020 for m1), with significant vacA s genotype-specific variance. The GIN-associated vacA s1a sequences clustered together, suggesting that aggressive Hp strains from a unique founder contribute to GC in the high-risk area studied.
