This is a multi-center, prospective, non-interventional real-world study. In a real-world environment, in line with the current status of the domestic diagnosis and treatment process, and on the premise of not increasing the burden of patients and medical resources, we explore the best indicators for predicting the outcome of patients with Clinical Research Coordinator (CRC) after surgery. The inclusion criteria for patients are perioperative patients with CRC. Real-world data analysis were conducted to determine whether immunization interventions versus non-interventions were able to improve patients' clinical outcomes (OS, PFS).
18-85 years old, regardless of gender;
Patients with newly diagnosed CRC who are planned to undergo surgery (including patients with metastases but still feasible for surgery);
Patients who have not been diagnosed for the first time and have not received surgical treatment and now planned to undergo surgery(e.g., patients after neoadjuvant radiotherapy and chemotherapy for middle and low rectal cancer).
Patients who refused to sign informed consent;
Patients complicated with other tumors;
Pregnant or lactating women;
People with a history of psychotropic drug abuse and unable to quit or those with mental disorders;
* 18-85 years old, regardless of gender; * Patients with newly diagnosed CRC who are planned to undergo surgery (including patients with metastases but still feasible for surgery); * Patients who have not been diagnosed for the first time and have not received surgical treatment and now planned to undergo surgery(e.g., patients after neoadjuvant radiotherapy and chemotherapy for middle and low rectal cancer).
