ClinConnect Summary

This clinical trial is looking at a new treatment approach for patients with recurrent rectal cancer, which is cancer that has come back in the pelvic area after initial treatment. The study will give participants a combination of radiation therapy and a drug called Toripalimab, which helps the immune system fight cancer. Patients aged 18 to 75 who have been diagnosed with this type of cancer and meet certain health criteria may be eligible to participate. Key requirements include having no other major health issues and not having received radiation treatment in the past six months.

Participants in the trial can expect to receive treatment that includes both chemotherapy and radiation, followed by surgery to remove the cancer. The main goal of the study is to see how many patients achieve a complete response, meaning no cancer is found after treatment. There are also other important goals, such as understanding how well patients do over time and how safe the treatment is. It's important to know that the trial is not yet recruiting participants, so those interested will need to stay updated on when it begins.
