Special Issue Information

Dear Colleagues,

Cancer is considered the most significant global health problem and is one of the leading causes of death and disease in the 21st century. Cancer is also a common disease in companion animals, with over 4.2 million dogs and cats diagnosed with cancer each year, of which 15% to 30% die. In addition, a number of neoplastic diseases in companion animals share many similarities with humans in terms of biological behavior, dissemination, and response to therapy, placing them in a strategic position for more rapid studies.

Cancer surveillance in animals is an important process that goes well beyond simple registration of cancer cases or calculation of incidence rates to include studies of cancer determinants and the effectiveness of prevention strategies and screening programs. Animal cancer data can also provide research data that can be used for epidemiological, clinical, and public health planning research.

The purpose of this Special Issue is to report on recent studies in the field of veterinary epidemiology and animal cancer data. Original research articles and reviews are welcome in this Special Issue. Research areas include, but are not limited to: Epidemiology of animal cancer and global registry initiatives; practice- and pathology-based data collection; regional or international studies; animal and comparative environmental oncology; and risk factor research.

This study aimed to characterize and describe the different lymphoma types and anatomical forms in cats in Hong Kong. The clinical and histopathological data of cats diagnosed with lymphoma by cytology and/or histopathology were collected from a large diagnostic laboratory in Hong Kong. In total, 444 cats were diagnosed with lymphoma over four years (2019–2022). Like other countries where there is a low prevalence of FeLV infection, the predominant form of lymphoma was gastrointestinal (abdominal). Nasopharyngeal and peripheral nodal lymphoma were the second and third most common forms of lymphoma. The large cell/high-grade lymphoma type was much more common than the low-grade/small cell lymphoma in the study population. Domestic short hair was the most commonly affected breed in our study (n = 259/444). Among the cats with identified T/B-cell status, B-cell lymphoma (n = 61/81) prevailed as the most common phenotype. This study describes and characterizes the different types of feline lymphoma in cats in Hong Kong, adding valuable information to the body of knowledge. Full article

In dogs, the spleen is a secondary lymphoid organ that can be affected by both neoplastic and non-neoplastic nodules. In general, few studies relate histopathological diagnosis to tumor size and the number of nodules in spleen biopsies. Some of these studies are inconclusive regarding the difference between neoplastic and non-neoplastic lesions and have small sample sizes or do not consider all splenic lesions. This study aimed to characterize splenic masses and determine risk factors for spleen tumors in dogs. A total of 507 histological reports corresponding to the diagnosis of splenic lesions in dogs from a private laboratory of animal pathology in the Metropolitan Region, Chile, were used. Data were analyzed by descriptive statistics and multiple logistic regression. The most frequent neoplastic and non-neoplastic diagnoses were hemangiosarcoma and hyperplasia, respectively. Most of the cases occurred in male (265 cases, 52.3%), senior (421 cases, 83%), and purebred individuals (342 cases, 67.5%). The most affected breeds were the Cocker Spaniel, German Shepherd, and Labrador Retriever. The most frequent lesion was a single nodule. The variables that exhibited a greater risk for the presentation of splenic neoplasia were male sex (odds ratio (OR) = 16.21; 95% confidence interval (CI) 1.741–150.879; p = 0.014), the presence of two or more splenic nodules (OR = 3.94; 95% CI 2.168–7.177; p < 0.001), an increase in nodule size greater than 2 cm (OR for quartiles 2, 3 and 4 of 2.2; 95% CI 1.036–4.941; p = 0.041, 2.9; 95% CI 1.331–6.576; p = 0.008, and 3.6; 95% CI 1.562–8.499; p = 0.003, respectively), and increasing age (OR = 1.23; 95% CI 1.048–1.436; p = 0.011). On the other hand, males exhibited a lower risk as age increases (OR = 0.76; 95% CI 0.615–0.928; p = 0.008). In conclusion, this study identified that males, multinodular presentation, nodule size, and age are risk factors for the occurrence of splenic neoplasia in dogs, knowledge that will contribute to the diagnostic management of dogs with spleen lesions.
