Assessing lead time of selected ovarian cancer biomarkers
Date:12/30/2009

ent with many of the established epidemiological risk factors for ovarian cancer," the authors write.

In an accompanying editorial, Patricia Hartge, ScD, of the Division of Cancer Epidemiology and Genetics at the National Cancer Institute in Bethesda, Md., applauds the authors for taking the field one step closer to successful screening designs by showing that the levels of certain biomarkers do not increase early enough to be used for screening.

"The results of Anderson et al. are not the last word in serum markers or in combinations of markers," the editorialist writes. "Serum markers likely will form a key element in any screening regimen, with the lead time and other parameters of each marker or combination of markers being taken into account. The careful evaluation technique applied in the current study fits into a staged approach necessary for testing performance of early markers of disease."
