Where this comes from

Abstract

Lee and colleagues report that increase in serum cholesterol is associated with improved clinical outcomes in patients with renal cell carcinoma treated with temsirolimus. Although these findings must be validated prospectively, it should also be determined if this marker is a true mechanism-based toxicity or an epiphenomenon associated with therapy.
