Evaluation of the efficacy of various methods of bronchial dysplasia treatment with the use of the comprehensive cytometric study

Dysplastic changes in the wall of bronchi were detected in 100 out of 121 patients with chronic non-specific lung diseases. Fiftyone patients received the conventional anti-inflammatory therapy and 49 patients were treated with intravascular laser blood radiation. Morphometric study carried out before and after the treatment allowed us to differentiate the signs of bronchial epithelium dysplasia of various grades of severity. The application of low-energy laser radiation for the treatment of pre-tumor changes in bronchial tree mucosa was shown to produce complete or partial responses in 95,3% of cases, whereas, the conventional treatment resulted in the dysplasia regression in 7,8% of cases. Differences were found to be statistically significant (p
