İzmir İlinde 2009-2022 yılları arasında teşhis edilen köpek ve kedi meme tümörlerinin retrospektif değerlendirmesi

Öz

Bu çalışmanın amacı, İzmir İlinde Ocak 2009-Aralık 2022 yılları arasında Bornova Veteriner Kontrol Enstitüsü Patoloji Bölümünde teşhis edilen köpek ve kedi meme tümörlerinin insidansını belirlemek ve meme tümörlü hayvanların ırk ve yaş özellikleri ile meme tümörlerinin varlığı arasındaki ilişkileri araştırmaktı. Bu amaçla her bir meme tümörü vakasına ilgili mevcut bilgiler arşiv kayıtlarından toplandı. Meme tümörlü köpek ve kediler 4 yaş grubuna ayrıldı. Meme tümörlerinin hematoksilen-eozin boyanmış slaydları histopatolojik olarak yeniden değerlendirildi ve sınıflandırıldı. Çalışma materyalini, 83 (37.55%) köpek ve 23 (30.66%) kediye ait 106 (%35.81) meme tümörü olgusu oluşturdu. Her iki türde en yüksek meme tümörü insidansı 8-11 yaş grubunda görüldü. Her iki türde yaş grupları ve ırklara göre meme tümörü insidansları arasında istatistiksel olarak önemli bir ilişki bulundu (p<0.05). Köpeklerde Terrier (28 olgu) (p=0.000) ve kedilerde melez ırk (14 olgu) (p=0.0003) meme tümörlerinin en sık görüldüğü ırklardı. Köpeklerde 83 meme tümörünün 64 (%77.10)’ü malign ve 19 (%22.90)’u bening; kedilerde ise 23 meme tümörünün 18 (%78.26)’i malign ve 5 (%21.74)’i bening karakterdeydi. Malign meme tümörleri, en çok Terrier ırkı köpeklerde (34.37%) ve melez ırk kedilerde (72.22%) belirlendi. Köpeklerde en sık teşhis edilen malign meme tümörleri, mikst tip karsinom (%51.56) (p=0.000) ve kedilerde tubuler karsinomdu (%50) (p=0.005). Köpeklerde bening mikst tümör (%47.37) ve kompleks adenom (%26.32) en sık gözlenen bening meme tümörleriydi. Kedilerdeki bening meme tümörlerinin (3 olgu, %60) çoğunluğunu basit adenom oluşturdu.

Retrospective Evaluation of Canine and Feline Mammary Tumors Diagnosed during the period from 2009 to 2022 in Izmir Province

Öz

The aim of this retrospective study was to determine the incidence of canine and feline mammary tumors diagnosed in the Pathology Laboratory of Bornova Veterinary Control Institute in Izmir Province between January 2009 and December 2022, as well as to analyse the relationships between the age and breed characteristics of affected animals and the presence of mammary tumors. For this purpose, the available information regarding each mammary tumor case was collected from archive records. Dogs and cats with mammary tumors were divided into four age groups. All hematoxylin and eosin-stained slides of mammary tumors were histopathologically re-evaluated and classified. The study material consisted of 106 (35.81%) mammary tumor cases, of which 83 (37.55%) belonged to dogs and 23 (30.66%) to cats. The highest incidence of mammary tumors in both species was observed in the age group of 8 to 11 years. A statistically significant relationship was found between the incidences of mammary tumors according to the age groups and breeds in both species (p<0.05). Terrier (28 cases) in dogs (p=0.000) and mixed breed (14 cases) in cats (p=0.0003) were the most commonly affected breeds by mammary tumors. In dogs, 64 (77.10%) of 83 mammary tumors were malignant and 19 (22.90%) were benign; in cats, 18 (78.26%) of 23 mammary tumors were malignant and 5 (21.74%) were benign. Malignant mammary tumors were detected more frequently in Terrier dogs (34.37%) and mixed breed cats (72.22%). The most commonly diagnosed malignant mammary tumors were mixed type carcinoma (51.56%) in dogs (p=0.000) and tubular carcinoma (50%) in cats (p=0.005). Benign mixed tumor (47.37%) and complex adenoma (26.32%) were the most frequently observed benign mammary tumors in dogs. Simple adenoma constituted the majority (60%, 3 cases) of benign mammary tumors in cats.
