Trial Summary

Do I need to stop my current medications for the trial?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What data supports the effectiveness of the treatment MRI-Guided Internal Radiation for Cervical and Vaginal Cancer?

Research shows that MRI-guided brachytherapy, a type of internal radiation, can significantly reduce tumor size in cervical cancer patients, with 11 out of 15 patients experiencing more than 80% tumor shrinkage. MRI helps in precisely targeting the cancer while minimizing damage to nearby organs, making it a valuable tool in treatment planning.12345

Is MRI-guided internal radiation therapy safe for humans?

MRI-guided brachytherapy for cervical cancer has been associated with late side effects, and high-grade toxicities have been reported, although improvements in the technique have reduced these compared to older methods.23678

How is MRI-guided internal radiation therapy for cervical and vaginal cancer different from other treatments?

MRI-guided internal radiation therapy, also known as brachytherapy, is unique because it uses MRI to precisely target the tumor, allowing for better dose optimization to the cancer while minimizing exposure to surrounding healthy organs. This approach can improve treatment accuracy and reduce side effects compared to traditional methods that may not use MRI for guidance.123910

What is the purpose of this trial?

This trial studies how well magnetic resonance imaging (MRI)-guided internal radiation therapy (brachytherapy) works in treating participants with human papillomavirus (HPV) associated stage IB2-IV cervical or stage II-IVA vaginal cancer. Using MRI guidance during brachytherapy applicator placement may improve treatment planning in participants with cervical or vaginal cancer.

Eligibility Criteria

This trial is for women with stage IB2-IVA cervical cancer or stage II-IVA vaginal cancer, recommended to receive chemoradiation including brachytherapy. It's not suitable for those with non-MRI-compatible anatomy, pacemakers, defibrillators, or conditions that prevent MRI use.

Inclusion Criteria

Women with advanced stage cervical cancer who are recommended to receive a specific type of treatment called chemoradiation, including brachytherapy.
Women with a specific stage of vaginal cancer who are advised to undergo a specific type of treatment involving chemotherapy and radiation therapy.

Exclusion Criteria

Patient or tumor anatomy that requires use of a non-MRI-compatible applicator
Patients with implantable cardioverter-defibrillator, pacemaker or other implanted device or medical condition which precludes MRI acquisition.
