研究人群
Patients suspected with colorectal cancer who come to our hospital to conduct colonoscopy procedure will be recruited for this study and will undergo a series of examinations.
Since this is a pilot study to obtain gut microbiome pattern on colorectal cancer patients, the number of samples is determined by the researchers: 100 subjects for neoplasm and 50 subjects for non-neoplasm (according to histopathology report)
描述
Inclusion Criteria:
- Age ≥ 35 years old
- Suspected with colorectal cancer and undergoing a colonoscopy procedure
- No history of colorectal cancer treatment
Exclusion Criteria:
- Unwilling to provide fecal and blood sample
- Incomplete colonoscopy procedure due to any reasons

Colorectal cancer suspects
Patients suspected with colorectal cancer who come to our hospital to conduct colonoscopy procedure will be recruited for this study and will undergo a series of examinations.
|
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.
Fecal samples will be taken before colonoscopy procedure to be tested for FIT and to evaluate the gut microbiome.

Gut microbiome
大体时间：pre-colonoscopy, approximately 1 day before colonoscopy
|
Gut microbiome examination will be conducted with next generation sequencing (NGS) method
|
pre-colonoscopy, approximately 1 day before colonoscopy

|
Carcinoembryonic antigen (CEA) serum level
大体时间：pre-colonoscopy, approximately 1 day before colonoscopy
|
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.
|
pre-colonoscopy, approximately 1 day before colonoscopy
|
|
Presence of NF-ҡB
大体时间：pre-colonoscopy, approximately 1 day before colonoscopy
|
NF-ҡB is a chronic inflammation marker found in colorectal cancer patients.
Presence of NF-ҡB is assessed with immunohistochemical method.
The result is considered positive if accumulated score ≥ 3.
|
pre-colonoscopy, approximately 1 day before colonoscopy
|
|
Fecal immunochemical test (FIT)
大体时间：pre-colonoscopy, approximately 1 day before colonoscopy
|
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
|
pre-colonoscopy, approximately 1 day before colonoscopy
