Special Issue Information

Dear Colleagues,

Cancer is one of the leading causes of death among people as well as among dogs and cats. In the last few years, small animal oncology has rapidly progressed . Molecular tests for specific cancers detection, liquid biopsies, and comprehensive genomic fingerprint analyses of cancer specimens are now a reality for dogs as well as people. Implementation of sophisticated diagnostic techniques such as liquid biopsy holds promise for the early diagnosis and better prognosis of various cancer types. The use of genomic fingerprint analysis in pets makes way for personalized medicine with individualized tailored treatments based on specific genetic mutations.

However, despite the recent general advances in small animal oncology, the number of anticancer drugs available for pets, especially tyrosine kinase inhibitors and immunotherapies, is insignificant compared with the array of treatment options available for people. Prognosis and treatment strategies for many tumors in dogs and cats have not changed much in the last 20 years. More research is required to understand the exact molecular biologies and pathologies of different types of neoplasia and to improve the treatment and quality of life for dogs and cats with cancer.

We are pleased to invite you to submit original research papers, reviews, case series, and cases reports regarding advances in small animal cancer diagnosis, prognosis, and treatment, as well as studies and reviews focusing on comparative and translational oncology.

We look forward to receiving your contributions.

Dr. Antonio Giuliano

Retrospective Study of T Cell Leukaemia (Large Granular Lymphocyte Variant) in Dogs Associated with Suspected Immune-Mediated Cytopaenia(s) in the Absence of Peripheral Lymphocytosis

Canine chronic large granular lymphocyte (LGL) leukaemia is commonly characterised by moderate to marked lymphocytosis but not neutropaenia. In humans, LGL leukaemia is often associated with autoimmune disorders, including immune-mediated cytopaenias (mainly neutropaenia). This presentation is rare in dogs.

Canine chronic large granular lymphocyte (LGL) leukaemia is commonly characterised by moderate to marked lymphocytosis but not neutropaenia. In humans, LGL leukaemia is often associated with autoimmune disorders, including immune-mediated cytopaenias (mainly neutropaenia). This presentation is rare in dogs. The aim of this retrospective study was to describe the clinical characteristics, treatments, and outcomes of dogs with chronic LGL leukaemia with suspected immune-mediated cytopaenia. Six dogs with a median age of 4.5 years (range 2–8 years) were included in the study. The most common presenting signs were pyrexia and lethargy. All dogs had severe neutropaenia (median neutrophil count 0.07 × 109/L), three had thrombocytopaenia (median platelet count 66 × 109/L), and one had anaemia (HCT 0.32 L/L). In all dogs, bone marrow cytology revealed infiltration of granular T lymphocytes; PARR analysis confirmed clonality in four, and bone marrow flow cytometry identified CD3+ CD8+ neoplastic cells in two cases. All patients received systemic chemotherapy, and the cytopaenias resolved after 1–19 weeks. Two dogs were euthanised 133 and 322 days after diagnosis, two were lost to follow-up after 224 and 357 days, and two were alive at 546 and 721 days. A subset of LGL leukaemia in dogs is associated with immune-mediated cytopaenia and has a unique clinical presentation. Full article

Repurposing drugs in oncology consists of using off-label drugs that are licensed for various non-oncological medical conditions to treat cancer. Repurposing drugs has the advantage of using drugs that are already commercialized, with known mechanisms of action, proven safety profiles, and known toxicology, pharmacokinetics and pharmacodynamics, and posology. These drugs are usually cheaper than new anti-cancer drugs and thus more affordable, even in low-income countries. The interest in repurposed anti-cancer drugs has led to numerous in vivo and in vitro studies, with some promising results. Some randomized clinical trials have also been performed in humans, with certain drugs showing some degree of clinical efficacy, but the true clinical benefit for most of these drugs remains unknown. Repurposing drugs in veterinary oncology is a very new concept and only a few studies have been published so far. In this review, we summarize both the benefits and challenges of using repurposed anti-cancer drugs; we report and discuss the most relevant studies that have been previously published in small animal oncology, and we suggest potential drugs that could be clinically investigated for anti-cancer treatment in dogs and cats.
