Describes the ability of a series of endocrine-derived compounds, i.e. CHRH, LHRH, somatostatin, anti-androgens, and aromatase inhibitors to exert a direct anti-neoplastic activity or to potentiate the activity of traditional chemotherapeutic agents on neuroendocrine and solid tumors. In addition, a new class of potent GH-releasers, GSHs/Ghrelin, endowed with important endocrine and extra-endcocrine action, is presented. Therefore, in addition to traditional chemotherapy, characterized by high toxicity and non-selective action on tumoral cells, the reader can find a new approach with more...
