Adrenocortical cancer (ACC) is a rare cancer with poor prognosis and scant treatment options. Mitotane alone, or in combination with cytotoxic chemotherapy, represents the referral current treatment for patients with unresectable ACC. Recent studies have shown that mTOR inhibitors suppress growth of ACC cells. This study aimed at evaluating the effects of mitotane in combination with mTOR inhibitors. In H295 and SW13 cells we tested the effects of a 6 day treatment with increa...

Background: Adrenocortical carcinoma (ACC) is an uncommon malignancy with a still scantily understood pathogenesis and generally poor prognosis. Surgery, performed at early stages, offers the best chance for cure, but unfortunately, it is often noncurative. Medical treatment produced disappointing responses. mTOR inhibitors, such as sirolimus (S) and temsirolimus (T), are promising antineoplastic drugs in several types of carcinomas.Methods: To evaluate ...

Chronic exposure to hypercortisolism significantly impacts on patient’s health and health-related quality of life (HRQoL). We developed a disease-generated questio-nnaire to evaluate HRQoL in Cushing’s syndrome (CS) (CushingQoL); in 125 (104 females) patients recruited in Spain, France, Germany, The Netherlands and Italy, clinical and hormonal data were collected and correlated with results of the generic SF-36 questionnaire, a question on self-perceived general heal...

The mTOR and IGF pathways have been suggested to play a role in the pathogenesis of pheochromocytomas (PCC). mTOR inhibitors, as sirolimus (S) and everolimus (E), as well as IGF1R antagonists could be a potential novel treatment for malignant PPC.The aim of this study was to evaluate the expression of the main components of the IGF/mTOR pathway in human PCC and to investigate the effects of the mTOR inhibitors S and E and of the IGF1R/insulin receptor (I...

Background: Adrenocortical carcinoma (ACC) is an uncommon malignancy with a still scantily understood pathogenesis and generally poor prognosis. Many patients with ACC need new treatment options. mTOR inhibitors, as sirolimus (S) and temsirolimus (T), are promising antineoplastic drugs in several kinds of tumors.Methods: In three human ACC cell lines (H295, HAC15 and SW13), we evaluated the mTOR and IGF2 expression at mRNA level (by qPCR) and at protein ...
