A prospective randomised clinical trial of the intra-operative use of 5-Fluorouracil on the outcome of dupuytren's disease

5-Fluorouracil reduces proliferation rates of fibroblasts, myofibroblast differentiation and contractility of ocular fibroblasts in vitro. This double-blind randomized clinical trial assesses whether intra-operative topical treatment with 5-fluorouracil reduces the recurrence rate after limited excision of Dupuytren's tissue. Patients with two-digit disease were randomized to having 5-fluorouracil (25mg/ml) treatment for 5minutes on one digit and placebo on the other.Fifteen patients were enrolled with 18 months follow-up. There were no peri-operative complications. Wound healing was not delayed and there was no deterioration in the flexion deformity of the 5-fluorouracil treated digits. Patients were subsequently assessed by joint angle measurement at 3, 6, 12 and 18 months. There was no significant difference between control and 5-fluorouracil treated digits.
