Potential of different kinds of laser irradiation in treatment of benign and malignant tumors of facial skin

摘要

The use of neodymium, holmium and diode lasers proved highly-effective in the treatment of facial skin cancers stage I-II (3,051)( basalioma--2,804, recurrent basalioma--165, squamous cell tumor--82) and benign tumors (2,157). Relapsed basaliomas after treatment from Pulsar-1,000 Ladoga- neodymium were reported in 1.6 and 3%, respectively. When pulsed neodymium lasers were used, repeat relapsed basalioma and recurrences of squamous cell cancer were detected in 4.2 and 4.9%, respectively. Overall malignancy recurrence frequency was 2,0% which was less than that after radiotherapy and surgery. Since the radiation penetration capacity of neodymium lasers is relatively high, their application is preferable in treatment of facial skin cancer stage I-II as well as exophytic or in-depth benign tumors. Holmium and diode lasers are better suited for destruction of superficial benign tumors. Good results should not be expected unless the right choice of radiation modality parameters, which take account of tumor localization and clinical course pattern, is made.
