One-year conditional survival of dogs and cats with invasive mammary carcinomas: A concept inspired from human breast cancer.

ABSTRACT: Numerous studies have described the prognostic factors of canine and feline mammary carcinomas (MCs), that is, variables that predict patient survival after diagnosis. But how does survival estimation evolve in patients that escaped early death from their cancer? In human oncology, conditional survival (CS), the probability of surviving X further years when cancer patients have already survived Y years, is used to analyse cancer outcomes in a long-term perspective. In this cohort of 344 dogs and 342 cats with surgically removed stage I to III invasive MCs, with a minimal follow-up of 2 years, we calculated the 1-year CS, that is, the probability for patients that have survived 1 year, to survive or to die from cancer during the subsequent year. The 1-year conditional specific survival prob
