Gastric cancer prevalence in patients with liver cirrhosis.
An increased risk for gastric cancer in patients with liver cirrhosis has recently been reported in epidemiological studies. The present endoscopic study was performed to further evaluate whether people with cirrhosis are at increased risk for gastric cancer development. We reviewed the medical records of all cirrhotic patients referred to our Endoscopic Service for portal hypertension screening and, therefore, cases of latent gastric cancer were observed. For a comparison, the prevalence (age and sex standardized) of latent gastric cancer in the general population was estimated hypothesizing a latency period of 5 years. Overall, 1379 patients with cirrhosis were selected from a total of 15 791 endoscopically examined different patients observed during the period 1982-1997. Histological assessment revealed the presence of gastric cancer in 10 patients (9 males and 1 female). There was a significant 2.6-fold (P<0.01) increase in prevalence of gastric cancer compared with that expected in our cirrhotic patients. In conclusion, our findings confirm that liver cirrhosis would seem to be a risk factor for the development of gastric cancer. Other studies are needed to evaluate the pathogenic mechanisms involved.
