title: [Antiangiogenesis therapy and hormone therapy--their resemblance and applications of prognostic and predictive factors].
abstract: Many new ideas to control tumor angiogenesis are now being tested in clinical trials. In considering strategies for clinical development of antiangiogenesis treatment, that of endocrine therapy might be particularly useful as a model. Endocrine therapy is a unique treatment used only for hormone-dependent tumors; however, its clinical fruits are exceptional in the entire history of cancer therapy. It is now clearly proven that long-term continuous treatment with antihormones brings a magnificent survival benefit for primary breast cancer patients. This benefit is tumor-phenotype oriented, where the hormone receptor is characterized as a potent predictive factor. Antiangiogenesis treatments seem to have several similarities with endocrine therapy, in that both treatments are cytostatic, stroma-targeting, time-dependent and less effective for large tumor burdens. A combination effect with chemotherapy is often observed with both treatments, at least in animal experiments. In a sense, anti-oncogene product therapy follows endocrine therapy in clinical development. Although antiangiogenesis treatments should be developed based on original concepts, the successful experience of endocrine therapy may provide many hints for the development of antiangiogenesis therapy.
