Loss of Succinate Dehydrogenase (SDHB) Expression in Midgut Carcinoids as Prognostic Factor: a New Marker of Personalized Cancer Medicine in Neuroendocrine Tumors? Abstract #581

Introduction: Gene mutations of SDH complex have been involved in the pathogenesis of cancer cells. These mutations are often associated with loss of activity of SDH subunity B and overexpression of HIF-1a, which play a central role in angiogenesis.
Aim(s): To investigate the expression of SDHB levels in carcinoids as prognostic marker.
Materials and methods: 31 carcinoid tumors were analyzed. Immunoistochemical (IHC) results for SDHB were assessed according to the staining intensity scored as 1 (low) or 2 (high).

#473 Succinate Dehydrogenase (SDHB): A New Marker of Malignancy in Midgut Carcinoids?
Introduction: The immunoistochemical (IHC) loss of SDHB expression was reported as a surrogate marker of malignancy in sporadic and familial pheocromocytomas/paragangliomas. SDHB loss is supposed to be tumorigenic (activation hypoxia signals).

Introduction: mTOR signalling pathway has emerged as a promising target for well-differentiated endocrine pancreatic carcinoma therapy. Because of varying behavior, INT are usually excluded from clinical trials employing the mTOR inhibitor, RAD001.
