Can a shorter radiation course beat anal cancer?
NCT ID NCT07775209
First seen Aug 20, 2026 · Last updated Sep 16, 2026 · Updated 3 times
Summary
This phase 2 trial is testing whether a shorter course of radiation therapy, given alongside standard chemotherapy, can effectively treat high-risk anal cancer. The standard treatment typically requires about 6 weeks of daily radiation, which can be a heavy burden for patients. The new approach uses a 23-fraction radiation schedule designed to be shorter while aiming to deliver a similar tumor-killing dose. The study will measure how many patients achieve a complete response at 6 months and will also track side effects and long-term outcomes.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Hypofractionated radiation therapy given with standard chemotherapy (mitomycin C and capecitabine)
- What this could lead to
- If successful, this could offer a shorter, more convenient treatment option for anal cancer patients, potentially reducing the burden of daily hospital visits.
- What could go wrong
- This is an early-phase study with a small number of participants. The shorter radiation course may not control the tumor as effectively as the standard longer course, and there is a risk of increased side effects.

Inclusion Criteria: * Age 18 years or older * Histologically or cytologically confirmed non-metastatic anal squamous cell carcinoma meeting one of the following criteria: T2 tumor measuring ≥4 cm T3 or T4 disease Any node-positive disease * Patients with HPV-associated (p16-positive) perianal cancer are eligible if the tumor extends to the anal verge * Karnofsky Performance Status \>60 * Creatinine clearance \>30 mL/min * Considered by the investigator to be appropriate candidates for concurrent capecitabine and mitomycin C chemotherapy * Ability to understand and willingness to provide informed consent * For participants of childbearing potential: negative pregnancy test or documented absence of pregnancy per institutional standard within 14 days prior to registration * Participants of reproductive potential must agree to use adequate contraception during study treatment and for 90 days after completion of therapy Exclusion Criteria: * Prior pelvic radiation therapy * Uncontrolled intercurrent illness that, in the opinion of the investigator, would prevent safe receipt of radiation therapy or capecitabine * Prior or concurrent malignancy that, in the opinion of the investigator, could interfere with assessment of safety or efficacy * Current receipt of another investigational agent for treatment of anal squamous cell carcinoma
