What this trial studies

This study aims to evaluate the effectiveness of a 3D drug sensitivity test using micro tumors (PTC) to guide adjuvant therapy decisions for patients with colorectal cancer. Patients aged 18 to 75 who have undergone radical surgery will be randomly assigned to either a group receiving treatment based on the test results or a control group following standard clinical practices. The primary goal is to assess the consistency between the test outcomes and clinical prognosis, ultimately providing real-world data to support personalized treatment approaches for colorectal cancer.

Who should consider this trial

Good fit: Ideal candidates are patients aged 18 to 75 with colorectal cancer who require adjuvant therapy after surgery and have not received prior neoadjuvant treatment.

Not a fit: Patients with metastatic colorectal cancer or those unable to provide tumor samples will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to more personalized and effective treatment strategies for colorectal cancer patients, improving their chances of disease-free survival.

How similar studies have performed: While the use of drug sensitivity testing in cancer treatment is gaining traction, this specific approach using 3D micro tumor technology is relatively novel and has not been extensively tested in prior studies.
