Abstract:
Objective To investigate the efficacy of dermabrasion combined with aminolevulinic acid-based photodynamic therapy (ALA-PDT) for the treatment of nasal nodular basal cell carcinoma (nBCC).Methods Twentyfive patients who were pathologically diagnosed as nasal nBCC with lesion area ＞ 1 cm2 but no bone or cartilage involvement,were included in this study and treated with dermabrasion combined with ALA-PDT.At first,the part of tumor protruding outside the skin was removed by artherectomy,then dermabrasion was carried out.The wound surface was topically treated with 20％ aminolevulinic acid solution for 3-4 hours away from light immediately after surgery,then irradiated with LED light at a mean dose of 100 J/cm2 for 20 minutes.ALA-PDT was performed once a week for 3 consecutive weeks.The degree of and time required for wound healing were assessed,and tumor recurrence,cicatrization and appearance outcomes were observed during 1 year after surgery.Efficacy was assessed comprehensively.Results No postoperative wound infection occurred in these patients,and the average time for wound healing was (11.2 ± 1.3) days.During 1 year after the treatment,no recurrence was found,while cicatricial contracture developed in 1 case,mild proliferative scar in 3 cases,and depressed scar in 4 cases.All the patients were satisfied with the treatment outcomes,except 1 patient who was basically satisfied.Conclusions Dermabrasion combined with ALA-PDT is easy to operate with rapid wound healing,low postoperative recurrence rate and high degree of patient satisfaction,and is worthy of clinical promotion.
