Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults over 18 with histologically confirmed cervical cancer at specific stages who are eligible for curative radiation therapy.

Probably not a fit

Patients with metastatic disease or those who have contraindications to MRI examinations will not benefit from this study.

What this trial studies

This study explores the feasibility of using a magnetic resonance imaging (MRI)-only approach for adaptive external beam radiation therapy (EBRT) in patients with cervical cancer. By implementing the Varian Ethos therapy system, the study aims to streamline the treatment workflow and reduce the radiation dose to surrounding organs at risk by adapting the treatment to the patient's daily anatomy. The focus is on patients requiring curative treatment for specific stages of cervical cancer, utilizing MRI for precise treatment planning.

Why it matters

Potential benefit: If successful, this approach could lead to more effective and safer radiation therapy for cervical cancer patients.

How similar studies have gone: While the use of adaptive radiation therapy is gaining traction, this specific MRI-only approach is relatively novel and has not been extensively tested in prior studies.
