Trial Purpose

The purpose of this study is to:
1. To elucidate the mechanism involved in the sorafenib-induced hypophosphatemia and possible early effect of hypophosphatemia on bone mineral density
2. A secondary objective to assess the effect sorafenib treatment on evaluate left ventricular function (LVEF) and Beta-type natriuretic peptide in plasma.
