简要总结
The incidence and mortality of stomach cancer are higher in the French West Indies than in mainland France. The prevalence of H. pylori infection associated with this cancer remains unknown in these populations. The main objective of the study is to estimate the prevalence of H. Pylori detected by immunohistochemistry in patients newly diagnosed with cancer.
详细描述
Stomach cancer is the 4th most common cancer site in the world and the 3rd cause of mortality. It is associated with infection by the Helicobacter Pylori bacterium, which colonizes the gastric mucosa in 80% of cases. The decrease of the prevalence of H. pylori infection in developed countries with the advent of antibiotic treatments is responsible for the decrease in the incidence of stomach cancer. But in the French West Indies, stomach cancer remains in excess incidence and mortality compared to France. The prevalence of H. pylori infection remains unknown, both in general population and in patients with stomach cancer. Eating habits combining high consumption of salt, meat and smoked fish could partly explain these high incidences. Furthermore, recent observations suggest that environmental risk factors (pesticides pollution) could also be involved in the occurrence of this cancer. Estimating the prevalence of H. pylori in stomach cancers will improve the epidemiological knowledge of this cancer with high incidence rates and prevention measures.

结局指标
主要结局
detection of H. Pylori in immunohistochemistry
时间窗: Baseline
Detection of Helicobacter pylori will be performed by immunohistochemistry (IHC) on gastric biopsy samples collected at inclusion. The procedure aims to identify the presence of H. pylori antigens within the gastric mucosa using specific antibodies. The test will be conducted in a certified pathology laboratory according to standard diagnostic protocols. Results will be reported as positive or negative for H. pylori infection.
次要结局
- positivity of anti H. Hylori serology by Elisa test(Baseline)
