This clinical trial is focused on studying colorectal cancer with metastasis, which is a type of cancer that starts in the colon or rectum and spreads to other parts of the body. The study aims to explore the use of circulating tumor DNA analysis, a method that examines small pieces of DNA from cancer cells found in the blood, to guide treatment decisions for patients with this condition. The trial will involve several medications, including oxaliplatin, capecitabine, calcium folinate (also known as leucovorin calcium), irinotecan hydrochloride, and fluorouracil (also known as 5-FU). These medications are commonly used in chemotherapy, which is a treatment that uses drugs to kill cancer cells.
Participants in the study will receive treatment over a period of time, with some medications given through an intravenous infusion, which means they are delivered directly into the bloodstream through a vein, and others taken orally, which means they are swallowed in pill form. The study will compare the effectiveness of these treatments in preventing the return of cancer and improving overall survival rates. The goal is to determine if using circulating tumor DNA analysis can help doctors make better treatment choices for patients with oligometastatic colorectal cancer, which is a stage where the cancer has spread but is still limited to a few areas.
The trial will monitor various outcomes, such as the rate of patients who remain free from cancer recurrence two years after starting the study, the side effects experienced by participants, and the overall quality of life. By understanding these factors, the study hopes to improve the way treatments are selected and followed up for patients with metastatic colorectal cancer, ultimately aiming to enhance patient care and outcomes.
