Tiny study probes tumor oxygen levels in cervical cancer
NCT ID NCT03970083
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study measures oxygen levels inside cervical cancer tumors during a type of radiation called brachytherapy. Ten adult patients with cervical cancer will have tiny oxygen sensors placed in their tumors during the procedure. The goal is to see if oxygen levels relate to how well the cancer responds to treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could help doctors understand how tumor oxygen levels affect treatment outcomes, potentially guiding future therapies.
- What could go wrong
- This is a very small, early-stage observational study with only 10 participants, so results may not apply broadly. It does not test a new treatment.

Inclusion Criteria: * Participants must have a biopsy-proven diagnosis of cervical cancer for which interstitial brachytherapy is planned as standard treatment * Age 18 years or older * ECOG performance status of 2 or less (see Appendix A) * Patients who have received prior radiation or chemotherapy may be enrolled on this study * Participant is deemed to be an appropriate candidate for MR-guided brachytherapy by the radiation oncologist and the patient elects to be treated with MR-guided brachytherapy * Participant provides informed consent for prospective collection of relevant medical records for analysis of clinical outcome and treatment-planning techniques * Ability to understand and the willingness to sign a written informed consent document. Participant is willing and able to comply with the protocol for the duration of the study including undergoing treatment and scheduled visits and examinations including follow- up Exclusion Criteria: * Participants who have a contraindication to MRI identified by the MR procedure screening form, such as a pacemaker, aneurysm clip, inner ear implant, neurostimulator, or other non-MR-compatible device or implant * Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
