Clinical potential "field of cancerization" of the skin
The objective of the study was to study the clinical potential of the «field of cancerisation» in epidermal dysplasia of the skin. Object of research. 245 patients with epidermal dysplasia of the skin, of which 66 (26,9%) were patients with invasive form of squamous cell carcinoma of the skin, 71 (29,0%) were patients with non-invasive form of squamous cell carcinoma of the skin and 108 (44,1%) were patients with actinic keratosis. Materials and methods. Personified data of patients with epidermal dysplasia of the skin. Statistical data processing was carried out using the «Statistica 7.0» program. Results. It has been established that the level of annual progression of epidermal dysplasia of the skin for patients with actinic keratosis was 1.4%, for patients with squamous cell carcinoma in situ and сutaneous squamous cell carcinoma 3.22% and 0.86% respectively. It has been established that the level of annual progression of epidermal dysplasia of the skin for patients with a combined course of the above listed skin pathology was significantly (p≤0.05) higher and amounted to 8.8%. Conclusions. The presented material is highlights the results of a five-year observation of patients with actinic keratosis, squamous cell carcinoma in situ and сutaneous squamous cell carcinoma.
