Summary
Brief summary (as posted)
This phase I/II trial investigates the side effects of interstitial brachytherapy and to see how well it works in limiting the growth of large kidney cancer masses in patients with kidney cancer that have refused or are unable to undergo surgery or ablation (unresectable/unablatable). Brachytherapy, also known as internal radiation therapy, temporarily introduces a radiation source into or near the tumor to eradicate the tumor cells. Giving brachytherapy may potentially reduce the size of the kidney cancer mass that would otherwise not be amenable to surgical management and translate into lower risk of spread.

Arms (1)
- type
- EXPERIMENTAL
- label
- Treatment (interstitial brachytherapy)
- description
- Patients undergo interstitial brachytherapy for 1-2 fractions in the absence of disease progression or unacceptable toxicity. Patients who undergo 2 fractions may receive both fractions in the same day or on 2 separate days over 2 weeks.
- interventionNames
- Procedure: Interstitial Radiation Therapy
Primary outcomes (2)
- measure
- Dose limiting toxicity (DLT)
- timeFrame
- From the first administration of study therapy up to 60 days
- description
- A 3+3 safety lead-in phase will be employed in order to determine the DLT for interstitial renal brachytherapy. Grading of DLTs will follow the guidelines provided in the Common Terminology Criteria for Adverse Events version 5.0 criteria.
- measure
- One year (12-month) linear growth rate
