New tumour markers: “Spot the differences”

The term “cancer” (from the Greek karkinos, which means sea crab) was used for the first time by Greek doctor Hippocrates five hundred years b.C. to define the tumours that he observed in his patients.

With each new publication of coronary artery disease (CAD) data from the Women’s Health Initiative (WHI) study, the inevitable reaction is “Why on earth did the WHI investigators claim in 2002–2004 that postmenopausal hormone therapy has deleterious effects on the risk for CAD, when, from the beginning, they were aware of the importance of the age factor in this clinical scenario"”. Women in the age group of 50–59 years who participated in the estrogen-alone arm of the WHI study were asked immediately after the early cessation of the trial to become part of an ancillary study – the WHI-CACS – which looked at the magnitude of coronary calcifications measured by ultra-fast coronary CT. Coronary calcium deposits develop as part of the atherosclerosis process and correlate well with findings of coronary angiography. more
