Rectal cancer after a complete response to chemoradiotherapy.

George William

Rectal cancer is a type of cancer that develops in the rectum, which is the last part of the large intestine before the anus. Chemo radiotherapy is a common treatment for rectal cancer, which involves a combination of chemotherapy and radiation therapy. In some cases, patients with rectal cancer may achieve a complete response to chemo radiotherapy, which means that there is no evidence of cancer remaining after treatment. However, even after a complete response, there is still a risk of cancer recurrence. A study published in the journal JAMA Oncology in 2021 analyzed the risk of cancer recurrence in patients with rectal cancer who achieved a complete response to chemo radiotherapy. The study included 485 patients who underwent chemo radiotherapy for rectal cancer and achieved a complete response.
