RESUMO
BACKGROUND/AIMS: Gastritis cystica profunda (GCP) is a rare disease that is characterized by a hyperplastic and cystic dilatation of the pseudopyloric gland with submucosal invasion. GCP is regarded as a benign lesion. However, there is some controversy regarding its malignant potential. This study reviewed the clinical features and association with malignancy. METHODS: From January 2001 to June 2005, 1,010 cases of resected and 1,228 cases of an endoscopic mucosal resection or polypectomy were examined. RESULTS: Thirty-nine cases (1.7%) were confirmed pathologically and were not associated with prior gastric surgery mostly. The mean age was 60.0+/-11.4 years old and there were 29 male patients. The body was most commonly located on the longitudinal axis (57.1%). Eleven cases (28.2%) were not associated any other gastric lesion, the majority of which were the polypoid type (82.0%). However, two cases were found as a hypertrophic mucosal fold, and a submucosal tumor, respectively. Seventeen cases (43.6%) were associated with early gastric cancer. CONCLUSIONS: Despite its rarity, GCP should be considered when an endoscopically polypoid lesion or submucosal tumor (SMT) is found. Because of its association with early gastric cancer or adenoma, more study will be needed to examine the relationship between GCP and gastric carcinogen

Ames Salmonella assay and sister chro-matid exchanges in CHO cell were used to study the mutagenicity of Size-fractionated indoor air particles from the areas with high incidence of lung cancer in Xuanwei county.Two states skin tumor test was used to study the Carcinogenicity.The results indicate that:all size-fractionated Particles have mutagenicity and carcinogenicity,the more the size is smaller,the more the mutagenicity and carcinogencity is stronger.
