Arginine-free diet with chemoradiation before rectal cancer surgery

Rectal Neoplasms

Part of Cancer, Digestive system clinical trials.

This trial tests whether avoiding arginine (a protein building block) in the diet during chemoradiation can make the tumor shrink more before surgery for locally advanced rectal cancer. It may help reduce side effects and improve surgical outcomes.

Summary written for real people, not researchers, by Clin2.

Before-surgery radiation and chemo for rectal cancer

This study tests a specific “before surgery” treatment (radiation plus chemotherapy), followed by more chemotherapy to improve outcomes in people with certain types of rectal cancer. You might be considered if your cancer is locally advanced but not spread to distant organs.

Testing shorter rectal radiation with chemotherapy plus immunotherapy

This Phase 2 study tests whether a shorter course of radiation, combined with chemotherapy (CAPOX) and an immunotherapy drug (tislelizumab), can control middle and low rectal cancer. It may also help people who strongly want to keep their anus, if the cancer and overall health fit the study rules.

Leucine plus chemoradiation before surgery for rectal cancer

This trial tests whether adding leucine (a simple amino acid) to standard chemoradiation before surgery can help shrink rectal cancer and improve outcomes. It is for people with locally advanced rectal cancer that hasn't yet spread to other organs.

Chemo and immunotherapy before surgery for rectal cancer

This trial tests a combination of chemotherapy and an immunotherapy drug (a PD-1 inhibitor) given before surgery for locally advanced rectal cancer. The goal is to see if this approach can improve outcomes compared to standard treatment.

Ketone supplement with radiation and chemo for rectal cancer

This study tests a combination of a special diet supplement (beta-hydroxybutyrate), short radiation therapy, immunotherapy, and chemotherapy before surgery for locally advanced rectal cancer. The goal is to see if this approach helps shrink the tumor and improve treatment outcomes.
