Temozolomide TMZ as an orally applicable chemotherapeutic substance has been proven to be effective and well tolerated with occasional moderate toxicity especially for brain tumors and an application to prostate cancer cells seemed to be promising. Unfortunately TMZ was inefficient in the treatment of symptomatic progressive hormone-refractory prostate cancer HRPC . The reasons could be a low sensitivity against TMZ the short plasma half-life of TMZ non-adapted application regimens and additionally the aneuploid DNA content of prostate cancer cells suggesting different sensitivity against .
