Retrospective evaluation of blood copper stable isotopes ratio 65Cu/63Cu as a biomarker of cancer in dogs
Previous studies in humans with breast, colorectal or liver cancer showed that neoplasia was associated with a modification of the blood ratio between 65Cu and 63Cu (∂Cu). The aim of the present study was to compare the blood ∂Cu of dogs with cancer to healthy controls or dogs with non‐oncologic dis...

The aim of the present study was to compare the blood ∂Cu of dogs with cancer to healthy controls or dogs with non‐oncologic disease. One hundred and seventeen dogs were included in the study (35 dogs with cancer, 33 dogs with non‐neoplastic disease, and 49 healthy controls). The ∂Cu of dogs with cancer was significantly lower than the ratio of healthy controls (P |
