There is an increasing need for more accurate prognostic and predictive markers in veterinary oncology because of an increasing number of treatment options, the increased financial costs associated with treatment, and the emotional stress experienced by owners in association with the disease and its treatment. Numerous studies have evaluated potential prognostic and predictive markers for veterinary neoplastic diseases, but there are no established guidelines or standards for the conduct and reporting of prognostic studies in veterinary medicine. This lack of standardization has made the evaluation and comparison of studies difficult. Most important, translating these results to clinical applications is problematic. To address this issue, the American College of Veterinary Pathologists' Oncology Committee organized an initiative to establish guidelines for the conduct and reporting of prognostic studies in veterinary oncology. The goal of this initiative is to increase the quality and standardization of veterinary prognostic studies to facilitate independent evaluation, validation, comparison, and implementation of study results. This article represents a consensus statement on the conduct and reporting of prognostic studies in veterinary oncology from veterinary pathologists and oncologists from around the world. These guidelines should be considered a recommendation based on the current state of knowledge in the field, and they will need to be continually reevaluated and revised as the field of veterinary oncology continues to progress. As mentioned, these guidelines were developed through an initiative of the American College of Veterinary Pathologists' Oncology Committee, and they have been reviewed and endorsed by the World Small Animal Veterinary Association.

Similar to what occurs in Human Medicine, also in Veterinary Medicine, the prevalence of oncological diseases has significantly increased. The evolution of Veterinary Medicine, in last decades has brought changes in clinical paradigms, particularly concerning the relationship with the animal and also with the owner. More than any other specialty, members of the Veterinary Medical Team that work in the oncology field, are unavoidably forced to break bad news. This paper proposes the adaptation of the ABCDE model from Human Medicine to Veterinary Medicine. The adaptation of the ABCDE model for Veterinary Medicine improves communication with the owner and offers all the members of the Veterinary Medical Team better communication skills.

Le lymphome est l'une des tumeurs les plus communes tant chez le chien que l’humain. Chaque année, un nombre important de chiens développe ce cancer agressif. La majorité décédant un an suivant le diagnostic. Le lymphome canin est maintenant identifié comme un excellent modèle de recherche pour la tumeur chez l'homme, particulièrement en ce qui concerne la biologie moléculaire de la maladie. En conséquence, la recherche sur le lymphome canin sera bénéfique non seulement pour les chiens mais aussi pour l’oncologie humaine. Parmi les méthodes diagnostiques de choix pour dépister de façon hâtive le lymphome se trouve la mesure de marqueurs tumoraux. Ceci a l’avantage d’être peu invasive, simple et peu dispendieuse. Ainsi, dans le but d’évaluer la protéine VCP (valosin containing protein) comme biomarqueur tumoral dans les lymphomes canins à cellules B et T, nous avons évalué la protéine VCP par immunobuvardage sur sérums et tissus tumoraux de chiens atteints et par immunohistochimie sur des tumeurs de haut grade, grade intermédiaire et bas grade. Pour mieux définir l’expression de VCP dans les cellules cancéreuses, nous avons également examiné par immunobuvardage les niveaux de VCP dans 3 lignées cellulaires: CLBL-1, CL-1, et 17-71. Il s’avère que les lymphomes à cellules B de haut grade avaient une élévation significative du taux de VCP comparé aux tumeurs de bas grade (P < 0,05). De même, une accumulation importante de VCP a également été détectée dans les lignées tumorales comparées aux cellules mononucléaires du sang périphérique (P < 0,05). D’autre part, le taux sérique de VCP est resté similaire à ceux des chiens normaux. Ces résultats suggèrent une corrélation entre le taux de VCP et le degré de malignité des lymphomes à cellules B. En conclusion, la protéine VCP doit faire l’objet d’une évaluation approfondie pour déterminer son utilité comme marqueur pronostique.

O registo oncológico é uma ferramenta de trabalho de valor inquestionável no estudo epidemiológico das neoplasias numa dada população. Em Portugal e apesar da classe veterinária reconhecer o seu valor, ainda não existe nenhum registo oncológico veterinário e este tema têm sido tratado com pouca relevância. O tema da dissertação deste Mestrado Integrado pretende contribuir para o estudo epidemiológico da oncologia felina, através da apresentação de uma distribuição de lesões do foro neoplásico. A recolha de dados reportou-se a um período de três anos (2008-2010), a partir de material fornecido pelo laboratório de histopatologia da DNAtech. De um total de 992 amostras da espécie felina, nesse período de tempo, 707 (71%) foram referentes a lesões do foro neoplásico, deste universo, 285 (38,9%) reportaram-se ao grupo de tumores da glândula mamária, 226 (30,9%) aos tumores mesenquimatosos da pele e de tecidos moles; 91 (12,4%) aos tumores epiteliais e melanocíticos da pele; 52 (7,1%) aos tumores do aparelho digestivo; 40 (5,5%) aos tumores do sistema hematopoiético, 16 (2,2%) aos tumores que afectaram o olho e ouvido; 5 (0,7%) ao aparelho urinário; 4 (0,5%) ao aparelho respiratório e, finalmente com menor frequência 13 (1,7%) foram classificados em outros grupos e sistemas (osso e articulações, aparelho endócrino, aparelho reprodutor e indeterminados). Observou-se uma proeminência nos tumores de origem maligna (75%), assim como para os tumores do sexo feminino (66%), o grupo de animais com 10 anos foi aquele que apresentou maior número de tumores. A diferente distribuição das neoplasias felinas observadas neste estudo, comparadas com os registos existentes noutros países enfatiza a necessidade da criação do nosso próprio registo oncológico.

The purpose of this paper is to establish criteria that could guide the diagnosis, prognosis and treatment of canine mammary neoplasias. It was elaborated during the Mammary Pathology Meeting: Diagnosis, Prognosis and Treatment of the Canine Mammary Neoplasm, held on November 6 th and 7 th, 2010 in Belo Horizonte - MG, Brazil, sponsored by the Laboratory of Comparative Pathology - UFMG, with the support of the Brazilian Association of Veterinary Pathology (ABPV) and Brazilian Association of Veterinary Oncology (ABROVET). Academics from several regions of Brazil were present and contributed to this work.
