I have a letter to the editor in this week's Journal of the American Medical Association (JAMA) addressing the potential for using genetics to better guide choices of chemotherapy regimens (Anesi GL. Genetically Guided Choices for Chemotherapy. JAMA. 2008;299(13):1543-1544.). I cannot post the PDF or text due because it is copyrighted, but anyone on a university network probably has access (try here).
