Several studies have investigated the long-term evolution of corpus-predominant gastritis after H. pylori eradication and its impact on atrophic gastritis and intestinal metaplasia. One study by the scientist followed up patients with corpus-predominant gastritis for a period of five years after successful H. pylori eradication. They found that while the overall severity of gastritis decreased after eradication, atrophic changes in the gastric mucosa persisted in a subset of patients. Specifically, they observed that patients with more severe baseline gastritis were more likely to develop atrophic gastritis despite eradication therapy .Similarly another study by scientist assessed the long-term effects of H. pylori eradication on the histopathological changes in the gastric mucosa. They found that while eradication led to a reduction in overall gastritis activity, there was a persistent risk of developing atrophic gastritis and intestinal metaplasia in patients with corpus-predominant gastritis.
These findings suggest that even after successful eradication of H. pylori, patients with corpus-predominant gastritis may still be at risk of developing atrophic gastritis and intestinal metaplasia, which are important factors in the progression to gastric adenocarcinoma. It highlights the need for long-term surveillance and monitoring of these patients to detect any progression of the disease and initiate appropriate interventions. It is worth noting that the studies mentioned above represent a fraction of the available literature on this topic, and on-going research continues to expand our understanding of the long-term effects of H. pylori eradication on gastritis and its role in gastric cancer development [1].
The study aims to determine the incidence rates of gastric cancer in each step of the disease progression, from chronic gastritis to precancerous conditions. By tracking the occurrence of gastric cancer cases, researchers can gain insights into the association between these precursor stages and the development of gastric cancer. The study also attempts to identify factors that are correlated with a persistent high-risk for developing gastric cancer. By analysing various patient characteristics, lifestyle factors, and disease parameters, researchers aim to identify markers that can help identify individuals who are at an increased risk of developing cancer .Furthermore, the study acknowledges the role of endoscopy in both screening and surveillance for gastric cancer. Based on the prevalence rates and disease evolution observed in the study, researchers hope to develop an improved strategy for identifying the target population that would benefit the most from screening and surveillance endoscopy. This knowledge can aid in implementing more effective and targeted screening programs, enhancing early detection and diagnosis of gastric cancer [2,3].
According to the study, there was a distinct correlation between increased risk and age. The risk of persistent high-risk status was found to increase by 1.2% for every year that patients received an index endoscopy and H. pylori eradication. This finding highlights the importance of eradicating H. pylori infection early in life, before any epigenetic or genetic instability occurs. The study suggests that screening and eradicating H. pylori at a young age can effectively reduce the risk of gastric cancer. The incidence rate of gastric cancer in this study was slightly higher compared to a previous study conducted in China, which may be attributed to the older age of the patients. Based on these findings, the study proposes that initiating screening for H. pylori infection early in life and eradicating the infection before precancerous conditions develop could be a cost-effective approach to reducing gastric cancer risk.
It's important to note that the specific details and recommendations regarding screening and eradication strategies may vary based on individual patient characteristics and regional factors [4]. Therefore, it is advisable to consult with healthcare professionals or medical guidelines for personalized recommendations. The study highlights the need for surveillance strategies for gastric cancer, regardless of whether the region has a high or low incidence of the disease. Gastric cancer remains more prevalent than esophageal cancer in many regions. Although guidelines recommend surveillance for individuals at risk of gastric cancer, the quality of evidence supporting these recommendations is low. The study contributes valuable data that can aid in scheduling surveillance endoscopies for individuals in different stages of Correa's cascade. Based on the study findings, it may be unnecessary to perform surveillance endoscopies for individuals in Correa's steps Lei (early stages of disease progression). However, surveillance endoscopies could be considered for individuals in higher stages of Correa's cascade, even those in the early stages of OLGA or OLGIM .Considering the increasing number of new gastric cancer cases each year, the findings of the study can be applied to clinical practice worldwide. However, it is essential to adapt surveillance strategies based on individual patient characteristics and regional factors [5].
The longitudinal study you described aims to investigate several key aspects related to chronic gastritis, precancerous conditions, H. pylori eradication, and the incidence of gastric cancer. The study intends to determine the prevalence rates of chronic gastritis and precancerous conditions in the study population. These rates will be stratified by age at screening, providing insights into the distribution of these conditions across different age groups. The study seeks to observe the evolution of chronic gastritis and precancerous conditions following H. pylori eradication. By monitoring these changes over a long-term follow-up period, researchers can assess the effectiveness of eradication therapy in reducing the severity of gastritis and mitigating the risk of disease progression.
In conclusion, successful eradication of H. pylori infection can halt the progression of Correa's cascade. However, eradication does not guarantee that gastric cancer will not develop, particularly in individuals who were already at Correa's steps IIIeV during screening. Age, OLGA stage I, and OLGIM stage I at screening were identified as independent factors correlated with a persistent high-risk of gastric cancer in long-term follow-up. Therefore, surveillance endoscopy may be considered for patients with OLGA/OLGIM stage1 but may be unnecessary for those with normal/CGI during screening.
