P. Clavere et al., POSTOPERATIVE INTERSTITIAL RADIOTHERAPY OF KELOIDS BY IRIDIUM-192 - ARETROSPECTIVE STUDY OF 46 TREATED SCARS, Dermatology, 195(4), 1997, pp. 349-352
Background: Keloids are clinically veracious scars characterized by a
high recurrence rate after excision alone (50-100%). Many adjuvant tec
hniques have been used with more or less convincing results. Objective
: The aim of this study is to show the efficiency of keloidectomy and
postoperative interstitial radiotherapy by an iridium 192 wire. Method
s: During a 14-year period, 39 patients with keloids (46 keloids) were
treated by this regimen. Seven patients had been previously treated b
y intralesional corticosteroids, surgery alone or postoperative inters
titial radiotherapy, without improvement. A dose of 12, Gy (7 keloids)
to 15 Gy (22 keloids) was delivered at a point 2.5 mm from the axis o
f the wire. For 17 keloids the dose schedule was 15 Gy at a point 5 mm
to the wire. The median follow-up was 7 months. Results: The overall
success rate is close to 63%. A recurrence occurred in 14 cases withou
t relation to the method used, the age or the localization of the lesi
ons. There were no side effects observed. Conclusion: Postoperative in
terstitial radiotherapy represents an effective, unconstraining and sa
fe treatment for keloids if the contraindications are respected.
