ABSTRACT
BACKGROUND:
In the treatment of keloids, the recurrence after surgical excision is relatively high. Various types of adjuvant therapy such as radiotherapy and corticosteroid injection have been used to reduce the recurrence.OBJECTIVE:
The aim of this study was to determine the appropriate time for initiating postoperative radiotherapy and to analyze factors associated with the occurrence and recurrence of keloids.METHODS:
Of these 37 lesions, 22 were located in the ear lobe, 6 in the helix of the auricle, 4 on the shoulder, 3 on the chest wall, and 2 on the abdomen. Causative factors were piercings (n=24), trauma (n=5), previous surgical lesions or bacillus Calmette-Guerin vaccination lesions (n=3) and acne (n=2). Radiation therapy was initiated within 24 h in 24 lesions, between 24 and 72 h in 6 lesions, and after more than 72 h in 7 lesions.RESULTS:
Seven lesions recurred, including 5 recurrences in high stretch-tension regions (p=0.010). Initial treatments were administered within 24 h in 1 lesion and more than 72 h after surgical excision in 6 lesions (p<0.0001). In the 19 patients with family histories, maternal and paternal genetic predispositions were present in 14 and 5 patients, respectively (p=0.033).CONCLUSION:
Radiotherapy should be initiated within 72 h of surgical excision. Location in a high stretch-tension region was significantly associated with recurrence. Patients with a family history showed a significant tendency toward maternal genetic predisposition. Therefore, combination therapy should be considered to reduce the occurrence and recurrence of keloids, and careful observation is required.
