ClinConnect Summary
This clinical trial is investigating the best length of treatment using a special type of immunotherapy called PD-1 monotherapy for patients with a specific type of rectal cancer known as dMMR/MSI-H. The goal is to determine the minimum number of treatment cycles needed to achieve a complete response before surgery, while ensuring that patients respond well to the treatment. Participants will receive this therapy before surgery and will be closely monitored every couple of cycles to see if they are responding well enough to proceed to surgery.
To be eligible for the trial, participants must be between 18 and 80 years old, have a confirmed diagnosis of stage II-III dMMR/MSI-H rectal cancer, and have not received any previous treatments like chemotherapy or radiation. They should also be in relatively good health with normal organ function. If you or a loved one is considering participation, you can expect regular check-ups to assess how well the treatment is working and monitor any side effects. The trial is currently recruiting participants, and those who join will be contributing to important research that could improve treatment options for rectal cancer patients in the future.
