ClinConnect Summary
This clinical trial is investigating a combination treatment for patients with locally recurrent colorectal cancer, which is cancer that has come back after initial treatment. The study is looking at how well a combination of three treatments—CapeOX (a type of chemotherapy), Bevacizumab (a targeted therapy), and an Anti-PD1 antibody (an immunotherapy)—works when given before surgery. The goal is to see if this approach can effectively shrink the cancer and make it easier to remove.
To be eligible for this trial, participants must have previously had surgery for colorectal cancer and have been diagnosed with cancer that has returned. They should not have received any cancer treatments in the past month, and their overall health must be stable. Participants can expect to receive this combination therapy, regular check-ups, and monitoring during the trial. It's important to note that there are specific health conditions that may prevent someone from joining, such as severe infections or certain autoimmune diseases. If you're considering participating, you'll need to provide informed consent and will be closely monitored throughout the study.
