BACKGROUND Although most patients with hereditary haemochromatosis have HFE C282Y mutations, the lifetime risk to HFE C282Y homozygotes of developing fatal diseases such as hepatocellular carcinoma is uncertain. We have carried out a cross-sectional study to determine the proportion of diagnosed hepatocellular carcinoma patients who are homozygous for the… (More)
BACKGROUND Some studies have suggested that breast cancer in black women is more aggressive than in white women. This study's aim was to look for evidence of differences in tumour biology between the two cohorts. METHODS This study compared the stage, grade and pathological expression of five immunohistochemical markers (oestrogen receptor [ER],… (More)
The potential clinical utility of genetic markers associated with response to fluoropyrimidine treatment in colorectal cancer patients remains controversial despite extensive study. Our aim was to test the clinical validity of both novel and previously identified markers of adverse events in a broad clinical setting. We have conducted an observational… (More)
BACKGROUND Genetic variation in folate metabolism has been associated with survival in utero, the success of in vitro fertilisation, multiple pathologies and longevity. METHODS We have looked at the prevalence of genetic variants of the enzymes MTHFR and TYMS in 2,898 DNA samples derived from five cohorts collected in the United Kingdom. The simultaneous… (More)
