[The effect of polychemotherapy on the oral mucosa in patients with acute myeloblastic leukemia].

Oral mucosa was examined in 23 patients with acute myeloblastic leukemia before and after cytostatic polychemotherapy. Lesions of the oral mucosa were observed in all patients after polychemotherapy: its color was changed, atrophic processes developed in it, and salivary secretion was impaired. Destructive ulcerative changes were revealed in 35% cases; terms of their appearance, regression, and epithelialization were established and a clear-cut correlation between their development and severity of leukocytopenia was detected. Ranging of stomatitis severity is proposed, according to which medium-severe stomatitis predominates in this patient population. The study will help develop more effective approaches to prevention and treatment of oral complications and improve the results of therapy of this most grave category of hematological patients.
