Improving radiation treatment for rectal cancer by targeting low oxygen levels in tumors

Official title: Tumor-Selective Radiosensitization by Targeting Hypoxia in Rectal Cancer

Funded at Beckman Research Institute/city of Hope · NIH-11046402 · Data updated 2026-11-12

This study is looking at how a special FDA-approved drug can help make radiation therapy work better for people with locally advanced rectal cancer by improving oxygen levels in tumors, with the hope that more patients can avoid surgery or have better results.

Who could benefit from this research

Could help

Ideal candidates for this research are patients diagnosed with locally advanced rectal cancer who are undergoing or have completed chemotherapy and radiation therapy.

Less likely to help

Patients with rectal cancer who are not eligible for chemotherapy or radiation therapy may not benefit from this research.

What this research studies

This research focuses on enhancing the effectiveness of radiation therapy for patients with locally advanced rectal cancer by addressing the issue of tumor hypoxia, which can make tumors resistant to treatment. The approach involves using an FDA-approved drug that inhibits mitochondrial oxygen consumption to sensitize tumor cells to radiation. By improving the response rates to radiation therapy, the goal is to increase the number of patients who can avoid surgery or achieve better outcomes. Patients will be monitored through imaging and assessments to evaluate their response to this innovative treatment.

Why it matters

Potential benefit: If successful, this research could lead to improved treatment outcomes for rectal cancer patients, potentially allowing more individuals to avoid surgery.

How similar studies have gone: Previous research has shown promise in targeting tumor hypoxia to enhance radiation therapy, indicating that this approach may be effective.
