This is attributed to a decrease in Helicobacter pylori infection and the use of refrigeration to preserve foods rather than using salt. The combination of chemotherapy, radiation therapy, and surgery may reduce the chance that stomach cancer will return.

Gastric cancer

In this population of patients, endoscopic surveillance is recommended. Abstract Gastric cancer is an aggressive disease that continues to have a daunting impact on global health. Helicobacter pylori VacA, a paradigm for toxin multifunctionality. Classification of gastric cancer Sporadic gastric cancer The majority of GC occurs sporadically and mainly affects people over the age of 45 years. Newer chemotherapy chemo drugs are also being studied. About 70 per cent of cases of stomach cancer occur in less developed countries with about half of all cases in Eastern Asia, particularly China. Virchows Arch. Perhaps, the decline can be attributed in part to improved food preservation with the advent of electric refrigeration,[ 10 ] increased accessibility to fresh fruits and vegetables year round, lower salt diets less salt preservation , the decreased use of tobacco[ 11 ] and eradication of Helicobacter pylori infections in endemic areas.

Recent research in countries with relatively low stomach cancer risk has provided some insight into risk factors. Abstract Gastric cancer is an aggressive disease that continues to have a daunting impact on global health. Treatment Chemotherapy drugs and combinations Some studies are testing new ways to combine treatments already known to be active against stomach cancer or other cancers.

Global cancer statistics. Researchers are looking at the genetic changes in tumor cells to identify specific genes, proteins, and other factors unique to the tumor.

There is a 15—fold variation in risk between the highest- and the lowest-risk populations. Schistosomes, liver flukes and Helicobacter pylori. For example, S-1 is an oral chemo drug related to 5-FU.

This review briefly summarizes the most important aspects of gastric cancers, which include epidemiology, risk factors, classification, diagnosis, prevention, and treatment.
