Primary Outcome Measures:
  • Keloid Scar Reduction [ Time Frame: 18 months ]
    Using a 3D scanner to observe the reduction of the scar volume measured in cubic centimetres

Estimated Enrollment: 100
Study Start Date: February 2011
Estimated Study Completion Date: January 2015
Estimated Primary Completion Date: January 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: 5-Fluorouracil
Patients with small keloidal scars to have intralesional 5FU injected
Drug: 5- fluorouracil
5mg of 5FU injected per 1cm square, at 6 week intervals for 30 weeks = 6 sessions
Active Comparator: Radiotherapy
Large keloid scars undergo extralesional excision and radiotherapy
Radiation: radiotherapy
after complete excision of keloid they have a single session of radiotherapy
Active Comparator: TAC Drug: Triamcinolone
TAC 10mg in 1ml injected intralesional
