A Phase 4 interventional study of Microneedling with 5-Fluorouracil and Intralesional 5-fluorouracil in Keloid Scars and Hypertrophic Scar, sponsored by Alexandria University. Completed at 1 site in Egypt. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-07-22.
Sponsored by Alexandria University · Phase 4, Interventional, and Treatment
The goal of this clinical trial is to learn about the efficacy and safety of microneedling-assisted 5-fluorouracil delivery in comparison with intralesional 5-fluorouracil, intralesional corticosteroid, and microneedling with saline for the treatment of pathological scars.
Hypertrophic scars and keloids are dermal fibroproliferative disorders unique to humans. They are common and usually occur following burns, trauma, inflammation, or surgery, but sometimes occur spontaneously. Despite an array of therapeutic approaches for scar therapy such as surgical excision, occlusive dressings, topical and intralesional corticosteroids, interferon, cryosurgery, radiation, pressure therapy, laser therapy, retinoic acid, and silicone gel sheeting, no single method provides complete benefit. For this reason, the medical care of HTSs and keloids remains clinically challenging. The study was conducted on 60 patients complaining of HTSs \& keloids.

Vancouver Scar Scale
To detect the Change in scar severity assessed by the Vancouver Scar Scale based on four scar characteristics (vascularity 0-3, pliability 0-5, height 0-3, pigmentation 0-2) with the minimum total score 0 (normal) and the maximum total score 13 (most severe scar). Higher scores after treatment mean worse outcome.
Time frame: 3 weeks
ImageJ Analysis
To objectively assess scar surface area. To quantify treatment effect, the percentage of change in scar area was calculated for each patient using the formula: ■("Percentage of change=" ("Post treatment area - Baseline area" /"Baseline area" )"×100" ), Higher scores mean worse outcomes.
Time frame: 3 weeks
Patient's satisfaction score
grade 0 (No satisfaction), grade I (poor less than 25%), grade II (fair 25-50%), grade III (Good 51-75%) and grade IV (Excellent 76-100%). The minimum total score 0 and the maximum total score 100. The higher scores mean a better outcome
Time frame: 3 weeks
visual analogue scale
to assess pain and pruritus. The minimum score is 0 indicated no pain or itching and the maximum score 10 represented the most severe pain or itching. The higher score mean a worse outcome
Time frame: 3 weeks
Plan to share: No — PD will not be shared due to participant confidentiality and ethical considerations
