Switching to anastrozole after the first 2 to 3 years of treatment is well tolerated and significantly improves event-free and recurrence-free survival in postmenopausal patients with early breast cancer.

Over the last few years, lipoprotein(a) [Lp(a)] levels have been investigated because clinical studies have related it to increased cardiovascular and cerebrovascular risk. Although it is known that serum Lp(a) concentrations are controlled genetically, little is known about its metabolism. We studied changes in the lipid profile and Lp(a) values in 57 patients (34 males and 23 females) affected by cirrhosis of the liver subdivided into Child's classes in order to assess whether this lipoprotein is sensitive to reduced liver protein synthesis. The patients presented with low total cholesterol, normal HDL-cholesterol (HDL-c), LDL-cholesterol (LDL-c), triglycerides, apoprotein A1 (Apo-A1) and apoprotein B100 (Apo-B100) concentrations, while Lp(a) concentrations seemed elevated. Grouping the patients into Child's classes revealed that all the lipid parameters investigated reduced as the disease progressed. Lp(a) reduced significantly between Child's Classes I and II and seems to be correlated with the severity of cirrhosis and the clinical worsening of the patients' conditions. These findings suggest that Lp(a) is not only an index of atherosclerosis risk, but also plays a role in monitoring liver functions.
