METHODS: The datasets were presented as timeseries of China-standardized annual incidence during 1988-2002. Linear regression model was used to analyze the incidence of stomach, liver, esophagus and colorectal cancers. RESULTS: Linear regression models for the time-series of stomach and esophagus cancer incidences for both men and women were statistically significant (P 〈 0.05); Regression models for liver cancer and for colorectal cancer were statistically significant for men (P 〈 0.05). CONCLUSION: The incidence rates of stomach and esophagus cancers for both men and women had down tendencies. For men, liver cancer had a down trend of the incidence and colorectal cancer had an upward trend of the incidence rate.展开更多

Search terms applied were "cancer, malignoma, esophageal, gastric, colon, colorectal, hepatic, pancreatic, CXCR4, SDF- 1α, and SDF-1β". CXCR4 expression correlated with dissemination of diverse gastrointestinal malignomas. The CXCR4 ligand SDF-1α might act as "chemorepellent" while SDF-1β might act as "chemorepellent" for CTLs, inducing tumor rejection. The paracrine expression of SDF-1α was furthermore closely associated with neoangiogenesis. CXCR4 and its ligands influence the dissemination, immune rejection, and neoangiogenesis of human gastrointestinal cancers. Inhibition of CXCR4 might be an interesting therapeutic option.展开更多
