Assessing lead time of selected ovarian cancer biomarkers | Science Codex



Assessing lead time of selected ovarian cancer biomarkers

"Concentrations of the biomarkers CA125, human epididymis protein 4 (HE4), and mesothelin began to rise 3 years before clinical diagnosis of ovarian cancer, according to a new study published online December 30 in the Journal of the National Cancer Institute. However, the biomarkers became substantially elevated only in the last year prior to diagnosis. The stage of the cancer at the time of marker elevation is not known.

CA125, HE4, mesothelin, B7-H4, decoy receptor 3, and spondin-2 have been identified as potential ovarian cancer biomarkers, but their behavior in the pre-diagnostic period, with the exception of CA125, has not been evaluated previously."
