Immunological Markers Screening for Colorectal Cancer

Study Overview
=================
Brief Summary
-----------------
Colorectal cancer incidence is increasing at an alarming rate in China. Recent reports concluded aberrant immunological function was associated with colorectal cancer outcome, however, the influence of immunocyte subgroup and immunologic factors on cancer outcome in colorectal cancer survivors is largely unknown.The investigators will explore the impact of immunocyte subgroup and immunologic factors on colorectal cancer disease-specific, disease-free and overall survival. The investigators will recruit approximately 5,000 patients as a prospective study cohort. During follow up, the investigators will explore the association of these factors with outcome of patients. The investigators believe that this project will improve the understanding of the impact of immunocyte subgroup and immunologic factors on colorectal cancer outcome.

Patients must have recovered from any effects of surgery. Evaluable disease must be present outside radiation field. At least 3 weeks must have elapsed after discontinuation of radiation therapy. Patients must provide a signed consent to participate in the study. Patients must complete all questionnaires. Exclusion Criteria: Patients with a proven history of peptic ulcer disease or gastroesophageal reflux. History of other malignancy, except for cancers that have been treated with a curative intent and patient is without evidence of active disease. Unresolved bacterial infection requiring treatment with antibiotics. Pregnant or lactating women may not participate in the study. Patients known to have HIV-1 virus infection because of the undetermined effect of this chemotherapy regimen in patients with HIV-1 and the potential for serious interaction with anti-HIV medications.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Disease-specific survival | Disease-specific survival is defined as the time elapsed from surgery to death due to CRC. Concretely, the cause of death obtained in the follow up was classified according to ICD-10 conventions. Disease-specific deaths included those with an underlying cause attributed to ICD-10 codes C18.0-C20.0 or C26.0. | 5 years | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Overall survival | Overall survival is defined as the time elapsed from surgery to the date of death from any cause. | 5 years |
