Integrated Chinese and Western Medicine Specialized Disease Cohort for Colorectal Cancer

Study Overview
=================
Brief Summary
-----------------
This is a nationwide cohort study on integrated traditional Chinese and Western medicine for colorectal cancer. The aim is to elucidate the distribution patterns of TCM syndromes in colorectal cancer and colorectal adenoma, reveal the relationship between TCM syndromes and diagnosis, prognosis, and prognosis. Based on biological samples, a phenotypic omics study of TCM syndromes in colorectal cancer and colorectal adenoma is conducted.

Detailed Description
-----------------
Colorectal cancer (CRC) is a common malignant tumor. The global cancer data in 2020 shows that the incidence rate of CRC ranks the third in the world, and the mortality rate ranks the second in the world. China is a large country of CRC. In 2016, China's incidence rate of CRC ranked second in malignant tumors, and its mortality ranked fourth. Both incidence rate and mortality are on the rise. At present, studies have shown that TCM plays an important role in the prevention and treatment of precancerous lesions, recurrence, and metastasis of CRC throughout the entire process. However, the clinical efficacy and mechanism of TCM intervention in the onset, progression, and metastasis of CRC still need further research evidence to support. This project aims to address the above issues, based on the advantages of TCM in tumor prevention and treatment, and actively construct the first large-scale integrated traditional Chinese and Western medicine CRC specialized disease queue in China. The study focuses on the key links of the precancerous lesions, recurrence, and metastasis progress of CRC and conducts a combination of disease and syndrome queue research. The project is based on the team's preliminary research results and collaborates with multiple regional diagnosis and treatment centers in China to form high-quality evidence-based medical evidence and unify TCM syndrome differentiation standards for CRC. At the same time, based on the study of specialized disease cohorts, the project breaks through the phenotype omics of TCM, further revealing the biological connotation of TCM syndromes in colorectal cancer, achieving the integration of Chinese and Western medicine, breaking through the bottleneck of basic research on CRC in TCM, assisting the research process of traditional Chinese medicine in preventing and treating CRC, and promoting the modernization of TCM.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Rectal cancer cohort<br>20,000 patients with rectal cancer will be included in this cohort and followed for five years. | |
| Colon cancer cohort<br>20,000 patients with colon cancer will be included in this cohort and followed for five years. | |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Overall survival of patients with CRC | Patients were recorded from the time they entered the study until their final death. | 5 years | 
| The detection rate of Colorectal Adenomatous Polyp. | In the follow-up plan, record the proportion of patients diagnosed with colorectal adenoma after colonoscopy examination. | 5 years | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Quality of life of CRC patients | The quality of life will be evaluated using the KPS score. The higher the KPS score, the better the patient's health condition. | 5 years | 
| Recurrence rate of CRC patients | Record the number of patients with recurrence at each time point. | 5 years | 
| Metastasis rate of CRC patients | Record the number of patients with metastasis at each time point. | 5 years | 
| Disease-free survival (DFS) of CRC patients | The evaluation criteria for DFS are as follows: after radical treatment, the patient has reached a disease-free state or complete remission, and after this, the time span until the first assessment of tumor recurrence or metastasis or death without recurrence or metastasis, the patient is in a tumor free state at this stage. | 5 years | 
| Progression-free survival (PFS) of CRC patients | The evaluation criteria for PFS are as follows: the time span from the start of tumor treatment upon patient enrollment to the first assessment of disease progression or death without progression, during which the tumor has basically not progressed. | 5 years | 
| The canceration rate of Colorectal Adenomatous Polyp. | In the follow-up plan, record the proportion of patients diagnosed with colorectal cancer after colonoscopy examination. | 5 years |
