Combination Radiotherapy for Recurrent Thyroid Cancer

This study is testing a combination treatment (CXRPT) of external beam radiation (XRT) and radioactive iodine (RAI) for people with recurrent thyroid cancer. The goal is to see if this combined approach can safely deliver higher doses of radiation to tumors than either treatment alone. You might be able to join if you are 18 to 85 years old and have papillary or follicular thyroid cancer that hasn't fully responded to previous treatments like surgery or radioactive iodine. The main way success will be measured is by looking at how safe the combined treatment is, specifically by tracking any side effects during and shortly after external beam radiation therapy. The current recruitment status for this study is unclear.

Study design
This is an open-label, Phase 1 interventional study aiming to enroll 48 participants. It will evaluate the safety of combining external beam radiation with radioactive iodine.
What's involved
Not specified in the trial record.
Compensation
Not stated in the trial record.
Follow-up
Safety will be measured during external beam radiation therapy (over a 2-week period) and within 30 days of completing external beam radiation therapy.
