PURPOSE

To analyse outcomes after early postoperative interstitial brachytherapy for recurrent keloids.

METHOD AND MATERIALS

We performed a retrospective analysis of 58 patients treated for 73 keloids between 1991 and 2005 of 27 retroauricular grooves or earlobes (37%), 23 on the neck (32%), 12 on the trunk or abdomen (16%) and 11 on the limbs (15%). All this lesions were histologically confirmed and were recurrent after medical and/or surgical treatments. In all cases they were symptomatic (prurit, pain ,inflammation or oozing). Sixty-four keloids from 51 patients were reviewed to analyse local control and functional results.

RESULTS

Median age was 28 years (range 13-71). Sex ratio male: female was 3:2. The median dose was 20 Gy (range 15-40) with a mean after loading time of 4 hours (range 1-6) and a mean dose rate of 0.7 Gy/h (range 0.4-1). Local control was 86% (55/64) after a median follow-up of 44,5 months. The 9 relapses occurred precociously (median: 6 months, range (2.5-24)) : 3 on the trunk, 4 on the neck, 1 on the abdomen and only one in the retroauricular groove. Among them, we noted one local infection treated by antibiotics. The influence of dose on risk of recurrence was not statistically significant. Initial functional troubles disappeared for 54/55 (98%) of controlled keloids

CONCLUSION

20 Gy postoperative interstitial brachytherapy with early after loading represents an effective treatment and provides excellent functional results for recurrent keloids.
