Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with clinically diagnosed unresected keloids who cannot undergo surgical excision.

Probably not a fit

Patients with prior radiation therapy to the treatment area or those with uncontrolled illnesses may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This pilot study aims to evaluate the safety and efficacy of radiation therapy (RT) for patients with unresected keloids. It will be conducted at a single institution and will focus on assessing toxicity within 10 weeks, as well as secondary outcomes such as keloid growth cessation, size reduction, symptomatic relief, and quality of life improvements. Patients will receive RT in the form of external beam radiotherapy or brachytherapy, with a total dose of 15 Gy delivered in fractions over three days. The study plans to recruit 15-20 patients over a period of 6-12 months.

Why it matters

Potential benefit: If successful, this treatment could provide a non-surgical option for patients suffering from keloids, potentially improving their quality of life.

How similar studies have gone: While there is existing literature on the use of radiation therapy for keloids, this specific approach is being evaluated in a pilot setting, making it a novel investigation.

Who can join: the full rules

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Clinically diagnosed keloid
* Surgical excision of keloid is either contraindicated or patient has declined treatment with surgical excision (Note: patients with keloids that recurred after previous resection are eligible, as long as the current keloid is either unresectable or patient has declined resection)
* Age ≥ 18
* Study specific informed consent provided

Exclusion Criteria:

* Prior RT to the area of interest that would result in overlap of radiation therapy fields
* Females of child bearing age without a negative serum pregnancy test prior to initiation of RT or unwilling to use contraception prior to and during the radiation course
* Keloids in areas where radiation therapy introduces unacceptable high risk of toxicity as determined by the treating radiation oncologist
* Uncontrolled intercurrent illness (e.g. symptomatic congestive heart failure, uncontrolled cardiac arrhythmia, or psychiatric situation) that would limit compliance with study requirements as judged by the treatment physicians
