Tumor prevalence in cats: experience from a reference diagnostic center in Mexico City (2006-2018)

Abstract

Records of referred cat cases received for diagnosis in the Department of Pathology of the National Autonomous University of Mexico, School of Veterinary Medicine and Animal Husbandry between 2006 and 2018, were reviewed to examine frequency of occurrence of neoplasms and associated demographic factors. To this end, the records of biopsies, necropsies and clinical information were analyzed to obtain data on animal sex and age, as well as neoplasm histotype, tissue of origin, and malignant/benign biological behavior. A total of 685 neoplasm cases were diagnosed during the study period, which represented 37.7% of all referred histopathological domestic cat cases. Epithelial neoplasms were the most prevalent (56% of cases), followed by mesenchymal tumors (27%), and hematopoietic and lymphoreticular neoplasms (17%). The most common tumor type was carcinoma (31%), followed by sarcoma (14%), adenocarcinoma (13%), lymphoma (13%), and adenoma (6%). Squamous cell carcinoma was the most frequent form of carcinoma (117 cases), followed by lymphoma (88 cases), and spindle cell sarcoma (56 cases). Approximately 85% of all cases corresponded to malignant neoplasms. A relationship between sex and histogenesis was observed, but there was no gender association with malignant behavior. Also, hematopoietic/lymphoreticular tumors occurred more frequently at an early age, than other types of neoplasms. To the extent of our knowledge, this is the first epidemiological report indicating the most common neoplasms in a Mexican domestic cat population.

Histological Origin and Anaplastic Behavior of Neoplasms Diagnosed in Canines in Guatemala (2015-2019)

“…In domestic animals such as dogs, there is a high manifestation of tumors, probably because they are allowed to reach old age, as well as their close relationship with humans regarding the environment and food. The analysis of neoplasms in a population based on their histological origin and anaplastic behavior, in addition to their association with characteristics of the patient's data, can contribute to accurate diagnoses, and early and more appropriate treatments in daily practice 9,17,19 .…”

Evaluation of cat tumors in Samsun between 2004-2022

“…Moreover, lymphomas were more frequently seen in male cats than female cats in another study (Dorn et al, 1968) but further research found that lymphomas had no significant correlation with sex (Shida et al, 2010). In addition, one study found that the median age of tumor incidence for cats was 9.5 years old (Pérez-Enriquez et al, 2020), while another reported a median of 9.14 years old (Rafalko et al, 2022;Pinello et al, 2022b). Further research found that tumors were most often detected between 6 and 14 years of age in cats (Pamukçu, 1954;MacEwen, 1990;Gülçubuk et al, 2005;Aydın et al, 2008).…”

Діагностика Новоутворень Молочної Залози У Кішок

“…Дані свідчать про те, що експресія цих білків змінюється в пухлинах і малігнізованих клітинних молочної залози, хоча ще не з'ясовано, чи є це причиною або наслідком неопластичного процесу [12]. Гормональні коливання, пов'язані з естральними циклами, впливають на розвиток пухлин молочних залоз [2,7,8,10,11,14]. Прогноз у більшості випадків неоплазій несприятливий, а смерть переважно пов'язана з місцевим рецидивом або метастазами.…”
