Retrospective Study on Survival Time of Cats with Mammary Carcinomas Undergoing Surgery Alone or with Adjuvant Chemotherapy

Modern Treatment Methods for Mammary Cancer in Cats

“…It was shown that with a large surgery volume due to the lymphatic vessel damage, the risk of seroma occurring (accumulation of serous fluid in the postoperative cavity), and the development of secondary lymphostasis in adjacent tissues and limbs increase. The frequency of seroma formation and secondary lymphostasis in sick cats underwent unilateral, one-, two-stage bilateral mastectomy is constantly and reaches 19.7%, 40.6% and 35.7%, respectively [9]. With the seroma development, active drainage of the operating cavity, a local compress, introduction of sclerosants (tetracycline, erythromycin, etc.)…”

“…However, it does not suppress dysplastic processes in the mammary glands that have developed after taking gestagenic drugs of long-lasting action. In the case of fibroadenomatosis of the mammary glands arising in intact and gib male and feline cats after taking progestogenic drugs, the antiprogestogen therapy with drugs based on aglepristone is recognized as the method of choice [9].…”

“…S.C.S. Cunha et al [9] recently conducted a randomized retrospective analysis of relapse-free and overall survival in 35 sick cats with resectable MC. Animals were randomized into two groups: received chemotherapy (n = 14) with mitoxantrone(n=12) or doxorubicin (n=2) and received no adjuvant therapy (n=21) after radical mastectomy with inguinal lymphadenectomy.…”

Epidemiology, Risk Factors and Pathomorphological Features of Mammary Tumors in Cats

“…The average age of sick cat at diagnosis is 10...12 years. [3,[12][13][14][15][16]; the median of age -10.3-12 years [3,13,17].…”

“…Multiple tumor lesions are common (40.8-80%), but they are rarely bilateral [3]. Abdominal mammary glands are more commonly affected than thoracic ones [13].…”
