Identification of Biomarkers of Risk for Pre-neoplastic and Neoplastic Lesions for the Development of Gastric Cancer

Identification of Biomarkers of Risk for Pre-neoplastic and Neoplastic Lesions for the Development of Gastric Cancer

Investigator propose the implementation of circulating biomarker monitoring, focusing on molecules related to the progression of gastric atrophy and/or associated with gastric cancer.

Monitoring these biomarkers will provide gastroenterologists with timely information on individuals at risk and, if values worsen during follow-up, will alert physicians observing these patients to evaluate them.

This monitoring will be offered to individuals who contact the IBO (Immunopatologia e Biomarcatori Oncologici) Unit at CRO (Centro di Riferimento Oncologico) in Aviano requesting an assessment of gastric function through pepsinogen and G17 gastrin level testing. Monitoring these biomarkers will provide a dynamic analysis of patients' gastric status, allowing for timely intervention in case of deviations from normal values. This proactive approach is important for the preventive management of gastric diseases, particularly for the diagnosis and monitoring of gastric atrophy and gastric cancer.

The IBO unit of the CRO in Aviano, together with the pathological anatomy and clinical units of gastroenterology, medical oncology, and surgery, will play a role in coordinating and implementing this monitoring program, thus contributing to the promotion of gastric health and the prevention of associated diseases.
