A Study of Circulating Immune Cell Activity Changes in Blood of Colorectal Cancer Patients

A Study of Circulating Immune Cell Activity Changes in Blood of Colorectal Cancer Patients

Previous studies have shown that colorectal cancer patients' prognosis and overall survival was related with immune cell expression in patients' tissue. However, the circulating immune cell activity changes in patients' blood has few studies. The purpose of this study is to analyze the variation of circulating immune cell activity in colorectal patients' blood which is classed as clinical staging.

The patients were classed as clinical staging

1. Early (stage1+2) and Late(stage3+4)
2. regional lymph node metastasis
3. Distant metastasis
4. TNM stage

Inclusion Criteria:

• patient who was planned to undergo colorectal cancer surgery.

Exclusion Criteria:

• age < 20 years old
• history of hypersensitivity reaction in propofol or sevoflurane
