Popis: | Results of clinical follow-up of the patient with squamous cell skin carcinoma of the nasal dorsum are represented. The patient underwent a course of combined photodynamic therapy (PDT) with distant gamma-ray therapy. Distant gamma-ray therapy was performed daily during 12 days (single dose of 3 Gy, total dose of 36 Gy) with the first session 24 h after injection of the photosensitization. For PDT the photosensitizer photosens at dose of 0,3 mg/kg was used. The method of prolonged PDT was applied, sessions of laser irradiation were performed daily during 7 days. The PDT sessions were carried out 2 h after session of gamma-ray therapy using distant (150 J/cm2, 40 mW/cm2) and contact (500 J/cm2, 100 mW/cm2) modalities. According to multiple cytological studies after treatment there were no signs of tumor, but inflammation. Four months after treatment according to cytological data continued tumor growth was detected. The patient underwent an additional course of PDT. Currently the patient is under follow-up: no recurrence during 8 months after repeated treatment. |
