Purpose: In early stage Dupuytren's contracture radiotherapy was applied to
prevent disease progression. Long-term results and Late toxicity of this t
reatment were evaluated in a retrospective analysis.
Patients and Methods: Between 1982 and 1994, 99 patients (176 hands) receiv
ed orthovoltage radiotherapy, which consisted of two courses with 5 x 3 Gy
(total dose: 30 Gy, daily fractionated; 120 kV, 4 mm AL), separated by a 6
to 8-week pause. The Dupuytren's contracture was staged according to the cl
assification of Tubiana et al. The long-term outcome was analyzed at last f
ollow-up between July and November 1999. The median follow-up was 10 years
(range 7-18 years). Late toxicity was assessed using the LENT-SOMA criteria
.
Results: In Stage N 84% and Stage N/I 67% of cases remained stable. 65% of
the cases in Stage I and 83% in Stage II showed progressive nodules and cor
ds. In case of progression we saw no complications after a second radiother
apy or salvage operation.
Conclusion: Radiotherapy effectively prevents disease progression for early
stage Dupuytren's contracture (Stage N, N/I). Moreover, in case of disease
progression despite radiotherapy salvage surgery is still feasible.
