Results of photodynamic therapy for basal cell carcinoma of the skin of the nose and auricles

Purpose. To analyze the results of treatment of patients with basal cell carcinoma of the skin (BCC) of the nose and auricles by photodynamic therapy (PDT) with a photoditazine photosensitizer. Materials and methods. In the study group of patients with BCC of the nose and auricles, most of the patients had nasal lesions – 115 (71.8%) people. Of these, 95 people (82.6%) had single tumors, and 20 people (17.4%) had multiple tumors. Lesions of the auricles and the external auditory canal were detected in 45 people (28.2%). Of these, 37 people (82.2%) had single tumors, and 8 people (17.8%) had multiple tumors. PDT was performed using a photoditazine photosensitizer and Atkus and Latus laser systems. Results. The immediate and long-term results of the treatment of BCC of the nose and auricles by the PDT method are analyzed. The immediate results were evaluated 2 months after the treatment. Complete resorption (PR) was achieved in 92.7% of cases, partial resorption (CR) was noted in 7.3% of cases. Relapses were diagnosed in the period from 4 to 36 months, with an average of 13.2 months. When analyzing long-term results after PDT treatment in patients with recurrent BCC of the nose and auricles, PR was noted in 90.5% of patients, CR – in 9.5%. Conclusion. The advantage of PDT is the possibility, if necessary, of repeated treatment courses for basal cell carcinoma of the skin. The PDT method is highly effective and well tolerated by patients, and it gives excellent and good cosmetic results.
