Antill Y, Mitchell G, Johnson S, Devereux L, Milner A, Di Iulio J, et al.
Cancer Epidemiol Biomarkers Prev . 2010 Jan; 19(1):265-74. PMID: 20056647
Purpose: Genomic alterations (including gene hypermethylation) are likely to precede the phenotypic changes associated with breast tumorigenesis. From a prospective collection of ductal lavage (DL) samples from women with a...

Clin Cancer Res . 2006 Dec; 12(23):6967-72. PMID: 17145815
Purpose: Germ-line variants in CHEK2 have been associated with increased breast, thyroid, prostate, kidney, and colorectal cancer risk; however, the prevalence of somatic inactivation of CHEK2 in common cancer types...

Antill Y, Mitchell G, Johnson S, Devereux L, Milner A, Phillips K, et al.
Cancer Epidemiol Biomarkers Prev . 2006 Jul; 15(7):1396-8. PMID: 16835342
Background: Loss of heterozygosity (LOH) in breast ductal lavage (DL) fluid has been reported to be a potential biomarker of malignant change. Interpretation of LOH is reliant on sufficient quality...
