Abstract
Background: Helicobacter pylori bacteria colonize the gastric mucosa and contribute to the occurrence and development of gastrointestinal diseases. According to the WHO, H. pylori bacteria are considered class I carcinogen.
Objectives: To detect Helicobacter pylori organisms by IHC expression of anti-H. Pylori antibodies in the explanted liver tissue; and enlarged perihepatic lymph nodes of cirrhotic liver; to detect any relation between the presence of the organism and histopathological findings in the liver tissue.
Materials and methods: This retrospective cross-sectional study included forty cases of cirrhotic patients with decompensated end-stage liver, recruited for liver transplantation based on combined clinical, radiological, and histological data. Samples were immunohistochemically analyzed for anti-H-Pylori antibodies to detect Helicobacter pylori organisms in the explanted liver tissue and enlarged perihepatic lymph nodes. The presence of the organism was correlated with clinic-pathologic variables.
Results: Eighty-five percent (34 cases) and seventy percent (28 cases) of cases were positive for anti-H-Pylori antibodies in the liver and lymph nodal tissues, respectively. More than eighty percent (14 cases) and half of the studied cases (8 cases) showed dysplasia in liver tissue expressing anti-H-Pylori-antibody in the liver tissue and the lymph nodes, respectively. All HCC cases expressed anti-H-Pylori antibody in the liver tissue and the lymph nodes. The relation between anti-H-Pylori antibody expression in lymph nodes and the presence of dysplasia or HCC in liver tissue was statistically significant (p-value = 0.037 and p-value = 0.041 respectively).
Conclusion: Our results conclude that there is a pathogenic role of extra-gastric H-Pylori colonization in lymph nodal tissue and in liver tissue, and it may be preventable by treating H. pylori, especially if treatment can be started very early.
期刊介绍:
Cancer is a very complex disease. While many aspects of carcinoge-nesis and oncogenesis are known, cancer control and prevention at the community level is however still in its infancy. Much more work needs to be done and many more steps need to be taken before effective strategies are developed. The multidisciplinary approaches and efforts to understand and control cancer in an effective and efficient manner, require highly trained scientists in all branches of the cancer sciences, from cellular and molecular aspects to patient care and palliation.
The Asia Pacific Organization for Cancer Prevention (APOCP) and its official publication, the Asia Pacific Journal of Cancer Prevention (APJCP), have served the community of cancer scientists very well and intends to continue to serve in this capacity to the best of its abilities. One of the objectives of the APOCP is to provide all relevant and current scientific information on the whole spectrum of cancer sciences. They aim to do this by providing a forum for communication and propagation of original and innovative research findings that have relevance to understanding the etiology, progression, treatment, and survival of patients, through their journal. The APJCP with its distinguished, diverse, and Asia-wide team of editors, reviewers, and readers, ensure the highest standards of research communication within the cancer sciences community across Asia as well as globally.
The APJCP publishes original research results under the following categories:
-Epidemiology, detection and screening.
-Cellular research and bio-markers.
-Identification of bio-targets and agents with novel mechanisms of action.
-Optimal clinical use of existing anti-cancer agents, including combination therapies.
-Radiation and surgery.
-Palliative care.
-Patient adherence, quality of life, satisfaction.
-Health economic evaluations.
