Evaluation of prognostic factors and survival rates in malignant feline mammary gland neoplasms

Abstract: The data suggest that inhibition of ovarian hormones and COX-2 may represent a therapeutic option for malignant feline mammary gland neoplasms. When evaluating disease progression, COX-2 scores and Ki-67 index should be analyzed in primary tumors and metastases. Histologic grade, HER-2 status and COX-2 scores were found to have a direct influence on OS. Prognostic factors allow for a better understanding of disease outcome in a condition that is characterized by a poor prognosis. The present work highlights th… Show more

“…In veterinary medicine, there are some histological grading systems with specific criteria (GILBERTSON et al, 1983;LAGADIC;ESTRADA, 1990;ELLIS, 1991;MISDORP et al, 1999), and, due to the importance of histological grading as a prognostic factor and of the differences found between canine and feline mammary neoplasia, a species-specific system has been sought (MILLS et al, 2015). However, the method proposed by Elston and Ellis (1991; (Table 3) is the most widely used and has been described as an independent prognostic factor in malignant mammary neoplasia in cats (SEIXAS et al, 2011;CAMPOS et al, 2015). Therefore, the authors believe this method should be preferred until clear evidence of improved prognostic stratification is demonstrated with novel methods.…”

“…Histological grade, evaluated by the Nottingham system, proposed by Elston and Ellis (1991), has been described as a reliable and independent prognostic factor in malignant mammary neoplasia in cats (SEIXAS et al, 2011;CAMPOS et al, 2015). The prognostic value was demonstrated by lower OS associated with more undifferentiated tumors (MILLANTA et al, 2002a;SEIXAS et al, 2011;CAMPOS et al, 2015).…”

“…Mais estudos são necessários para que sejam alcançadas as doses terapêuticas e as combinações de drogas com maior eficácia no aumento da sobrevida destes animais (GIMÉNEZ et al, 2010).Para os carcinomas mamários felinos, os tratamentos convencionais como cirurgia, quimioterapia e radioterapia podem não conferir benefícios reais em todos os animais ou em casos mais avançados. Desta forma, vários parâmetros clínicos, patológicos e moleculares têm atraído interesse como fatores prognósticos e/ou preditivos(GIMÉNEZ et al, 2010;ZAPPULLI et al, 2015).Atualmente, identifica-se na literatura uma série de estudos propondo marcadores imunohistoquímicos como fatores prognósticos nos carcinomas mamários felinos(MILLANTA et al, 2002a; MILLANTA et al, 2005c;MILLANTA et al, 2006b;SOARES et al, 2013;DE CAMPOS et al, 2016;MILLANTA et al, 2016a; SOARES et al, 2016e).MILLANTA et al, 2005c;RASOTTO et al, 2011); o fator de crescimento do endotélio vascular VEGF(DE CAMPOS et al, 2016); e os receptores hormonais de estrógeno(MILLANTA et al, 2005b;MILLANTA et al, 2006b; SOARES et al, 2016b) e de progesterona (MILLANTA et al, 2005a; MILLANTA et al, 2006b). A superexpressão de COX-2 foi significativamente maior em tecidos neoplásicos quando comparada aos tecidos mamários saudáveis.…”
