Eligibility Criteria

Eligibility Criteria

Sex: All

Age: 18+

Healthy Volunteers: Not accepted

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

Interventions and Outcome Measures

Arms

experimental: Radiotherapy for patients with nonresectable keloids

Patients will be seen by a treating radiation oncologist and treatment with the assigned dose schedule will be planned using either EBRT with electrons or high dose-rate radiotherapy (HDR) brachytherapy as deemed appropriate by the treating radiation oncologist. The treatment dose of 25 Gy in 5 fractions will be prescribed to the 90% isodose line.

Interventions

Radiotherapy

25 Gy in 5 fractions

Primary outcome measure

  • Treatment-related toxicities [ Time Frame: Up to 1 year (+/- 1 month) post radiotherapy ]
