Daganat típusok előfordulási gyakorisága egy onkológiai szakrendelőben

Abstract

Neoplastic diseases are getting more and more frequent in dogs. Unfortunately, there is not too much data available about the canine tumours in Hunagry, as there is no independent, unified canincal cancer registry in this country, which would include incidence, type of cancers, moreover the accumulation of some tumor sin cerain breeds. I analysed 1045 canine clinical reports, which were made between 2009 and 2013. The tumor diagnoses were achieved by cytological and histopathological methods. I examined the incidence of the benign and malignant tumours (benigne 7,75%, malignant 92,25%). For the better evaluation I included the tumor types into 5 groups according to their histopathological origin: epithelial, mesenchymal, haematopoetic and lymphoreticular, the tumors of unsure origin (histiocytoma, melanoma, malignant histiocytosis, mastocytoma), and the mixed type, less frequent (of central nervous, endocrine and genital origin). The most frequent tumors were of haematopoetic and the lymphoretikular origin (37,52%), the mesenchymal (29,75%) and the epithelial types (19,8%). The mean survival time was the highest of the haematopoetic and lymphoreticular tumors (157,7 days). The mean age of the animals was 8,16 years at the time of the diagnosis. The death of the animals occured at their 9,41 years. The mean survival time of all tumors was 117,94 days. There was marked difference in the incidence of tumor types between genders. Adenocarcinoma and carcinoma simplex was found to be more common in females than in males (mammary gland tumors). There was no significant difference between genders in case of mesenchymal and haematopoetic tumors. Tumors were found to be more commonly in mongrels, hungarian vizslas, golden retrievers, and St Bernard’s dogs. These data can be an important basis for epidemological researches dealing with canine tumors.
