Brief summary
This study aims to investigate the role of gut microbiome pattern and inflammation marker NF-ҡB in young-onset colorectal cancer
Interventions
Asia Pacific Colorectal Screening (APCS) is a validated tool to predict the risk of colorectal cancer in asymptomatic Asian population. The scoring system comprises of three categories: low risk (score 0-1), moderate risk (score 2-3) and high risk (score 4-7). Patients with moderate and high risk will undergo further examinations.
Blood samples will be taken before colonoscopy procedure to evaluate the level of serum CEA by ELISA method and to evaluate the presence of NF-ҡB by immunohistochemical method. 1. Carcinoembryonic antigen (CEA) is a well-known marker for colorectal cancer. A pre-treatment serum CEA level of ≥ 5 ng/mL is associated with poor prognosis in colorectal cancer patients. 2. NF-ҡB is a chronic inflammation marker found in colorectal cancer patients.
Fecal samples will be taken before colonoscopy procedure to be tested for FIT and to evaluate the gut microbiome. 1. Fecal immunochemical test (FIT) is a recommended screening method for colorectal cancer. Detection of hemoglobin over a certain level in fecal samples indicated a positive FIT. Patients with positive FIT will undergo further examinations. 2. Gut microbiome examination will be conducted with next generation sequencing (NGS) method.
