Results of postoperative (90)Sr radiotherapy of keloids in view of patients' subjective assessment.
OBJECTIVE
As treatment of keloids is mainly a cosmetic indication, the authors investigated, beyond the recurrence rate, the patients' satisfaction with the result and its correlation with objective medical findings.


METHODS
83 keloids of 66 patients had been irradiated after excision by a uniform protocol with 4 x 5 Gy (strontium- 90 [(90)Sr] surface applicator). A questionnaire was developed and sent out in which, above all, the satisfaction with the therapeutic and cosmetic outcome was obtained. These results were correlated with objective parameters and medical findings which were ascertained during an extra follow-up examination.


RESULTS
Among 18 of the 41 patients (44%), who had answered the questionnaire, 19 of the 53 keloids treated (36%) had relapsed. 61% of the patients were extremely or mainly satisfied with the therapeutic outcome, 51% extremely or mainly satisfied with the cosmetic outcome. The relief from former keloid-caused symptoms (therapeutic outcome: p = 0.0005; cosmetic outcome: p = 0.0011), the ear as keloid localization (p = 0.0008 and p = 0.0197), and male gender (therapeutic outcome: p = 0.0423) were significantly associated with higher satisfaction. The recurrence rate as well as the extent of radiation side effects had no significant influence on patients' assessment.


CONCLUSIONS
Cosmetic aspects like the dermal side effects and the patients' satisfaction should be taken into account when evaluating the results of radiotherapy in keloids.
