RESUMO
Dog-ear collection, Z-plasty, and W-plasty are often performed for excision of dumbbell-shaped keloids; however, these procedures require additional incisions or excision of normal skin. Thus, an S-shaped wound closure technique was performed. The keloid lesions were extralesionally excised above the deep fascia, and the wound edges were shifted in opposite directions along the major axis to form an S-shape. The incision was closed by applying deep fascial sutures, subcutaneous sutures, and superficial sutures. Postoperative external beam radiation therapy was started within 6 hours after surgery at a dose of 20 Gy applied in 4 fractions. All wounds were covered with silicone-gel sheeting and fixed with tape after suture removal. No intralesional corticosteroid injection or oral tranilast was administered. Corticosteroid tape was applied in cases with suspected postoperative recurrence. Scoring was performed using the Manchester Scar Scale. A total of 8 lesions were treated. Temporary erythema and scar elevation were observed in 2 chest lesions; however, both were flattened and turned white using corticosteroid tape. Other than these 2 lesions, there was no recurrence or complication. The mean score improved from 15.8 to 7.2. The S-shaped wound closure technique has 3 advantages. First, no additional incision or excision is required, and additional scarring and keloid recurrence can be avoided. Second, aesthetic results are good, and noticeably long and zigzag-shaped scars can be avoided. Third, dispersion of tension on the scar can be expected. Although the S-shaped wound closure technique has limited application, it is a useful option for keloid treatment.
RESUMO
PURPOSE: To evaluate factors associated with radiation-induced bronchiolitis obliterans organizing pneumonia (BOOP) syndrome after breast-conserving therapy. METHODS AND MATERIALS: A total of 702 women with breast cancer who received radiotherapy after breast-conserving surgery at seven institutions between July 1995 and December 2006 were analyzed. In all patients, the whole breast was irradiated with two tangential photon beams. The criteria used for the diagnosis of radiation-induced BOOP syndrome were as follows: (1) radiotherapy to the breast within 12 months, (2) general and/or respiratory symptoms lasting for >or=2 weeks, (3) radiographs showing lung infiltration outside the radiation port, and (4) no evidence of a specific cause. RESULTS: Radiation-induced BOOP syndrome was seen in 16 patients (2.3%). Eleven patients (68.8%) were administered steroids. The duration of steroid administration ranged from 1 week to 3.7 years (median, 1.1 years). Multivariate analysis revealed that age (>or=50 years; odds ratio [OR] 8.88; 95% confidence interval [CI] 1.16-67.76; p = 0.04) and concurrent endocrine therapy (OR 3.05; 95% CI 1.09-8.54; p = 0.03) were significantly associated with BOOP syndrome. Of the 161 patients whose age was >or=50 years and who received concurrent endocrine therapy, 10 (6.2%) developed BOOP syndrome. CONCLUSIONS: Age (>or=50 years) and concurrent endocrine therapy can promote the development of radiation-induced BOOP syndrome after breast-conserving therapy. Physicians should carefully follow patients who received breast-conserving therapy, especially those who are older than 50 years and received concurrent endocrine therapy during radiotherapy.
