The Investigation of the Mechanism of Cachexia Occurrence for Patients With Gastrointestinal Cancer

• Conditions: Cachexia

• Registration Number: NCT04594863
• Lead Sponsor: Peking Union Medical College Hospital

Brief Summary

The study is going to recruit patients with gastrointestinal cancer, collect clinical data and peripheral blood sample and possible fat samples. The expression of SIRT-6 in peripheral blood will be tested and connect with different status of cachexia of the patients. A mathematical model of the relationship between cachexia classification and SIRT-6 expression is going to constructed as anticipated.

Detailed Description

At the start of cancer develop, not all patients with gastrointestinal cancer manifest cachexia, it may be associated with SIRT-6 expression. This study will collect and test the peripheral blood sample of patients, use it as an important indicator of the degree of cachexia, and provide references for clinical drug intervention, prognosis and dietary intervention for cachexia patients. If possible, fat sample of the patients will be collected during surgery, and the adipose progenitor cells will be cultured to find the key target proteins by detecting differences in protein expression, changes in protein modification levels, and protein interactions.
