Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this project is to study the presence of cancer-associated adipocytes in oesogastric cancers and their possible links with myosteatosis. This research project has a retrospective component, the aim of which is to analyse the body component based on imaging in patients with oesogastric neoplasia in order to determine the incidence of myosteatosis and to study the relationship with oncological and prognostic data. The second part of the project is prospective and will collect biological material (skeletal muscle, adipose tissue, tumour, blood) for histological, molecular and genomic analyses and will analyse muscle function in patients with oesogastric cancer. It will address the role of adipocytes in the tumour microenvironment of oesogastric cancer, focusing on their interactions with the observed muscle myosteatosis and prognosis. In the future, it will help to identify signalling pathways, targets and patients who could benefit from appropriate treatment.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Oesophageal and gastric cancer pose a significant challenge to caregivers, both in terms of the complexity of its presentation and its treatment. At diagnosis, patients often present with malnutrition associated with sarcopenia, which has a significant impact on morbidity and mortality. Although loss of muscle mass has received much attention in cancer, muscle quality, particularly the accumulation of fat in muscle named "myosteatosis", may be considered as a better predictor of a patient's physical condition and ability to recover from cancer treatments. Studying the tumor microenvironment is essential to understanding the mechanisms underlying disease progression. Cancer-associated adipocytes (CAA), a major component of this tumor microenvironment, provide an interface for dialogue with the tumor through the secretion of pro-inflammatory cytokines, metalloproteases and the release of free fatty acids. They have been described as capable of stimulating tumor progression, particularly in breast cancer. However, their presence in oesogastric cancer and possible links with myosteatosis have not been described.
