Adrenocortical tumors occur as sporadic tumors, as part of the multiple endocrine neoplasia type 1 (MEN1) syndrome or as part of other hereditary disorders. We recently cloned the MEN1 gene, a tumor-suppressor gene located on chromosome 11q13. Subsequently, we showed that sequential somatic inactivation of both alleles of the MEN1 gene contributes to the development of some sporadic endocrine n...
BACKGROUND Acute adrenal hemorrhage is an uncommon entity. Although trauma is the most common cause of adrenal hemorrhage, non-traumatic etiologies have also been reported. We report an unusual case of a spontaneously ruptured adrenocortical carcinoma that initially presented as a critical massive retroperitoneal hemorrhage. The case was treated successfully using a combination of emergency int...
Ghrelin is expressed in normal human adrenocortical cells and induces their proliferation through growth hormone secretagogue receptor 1a (GHS-R1a). Consequently, it was of interest to us to determine whether acylated ghrelin and its predominant serum isoform, unacylated ghrelin, also act as factors for adrenocortical carcinoma cell growth. To examine a potential ghrelin-regulated system in adr...
Adrenocortical carcinoma is a rare malignancy. Due to late diagnosis and no adequate effective adjuvant treatment, prognosis remains poor. Only approximately 30% of these malignancies are confined to the adrenal gland when they are diagnosed, as these tumors tend to be found years after their genesis. Cardiac involvement of adrenal carcinoma is very rare. We report a rare case of a 7-year-old f...
BACKGROUND We compared the oncologic effectiveness of open adrenalectomy and endoscopic adrenalectomy in the treatment of patients with localized adrenocortical carcinoma. METHODS One hundred fifty-six patients with localized adrenocortical carcinoma (stage I/II) who underwent R0 resection were included in an Italian multiinstitutional surgical survey. They were divided into 2 groups based on...
Aim Adrenocortical carcinoma (ACC) is characterized with excessive hormone production. We therefore investigated expression of hormone-related genes in ACC. Results We queried status of 14 key genes directly involved in adrenal hormone production and found HSD17B4 expression was upregulated in 39% of ACC cases on top of all queried genes. Overexpression of HSD17B4 was significantly associate ...
Tumors derived from a Li-Fraumeni syndrome cancer-susceptible family were examined for expression of the retinoblastoma susceptibility gene (RB). Whereas RB expression was normal in a primary breast carcinoma and its metastases from one member of this family, overexpression of RB was found in an adrenocortical carcinoma from another family member. This was in contrast to normal RB expression in...
We report a case of preclinical Cushing's syndrome in a 54-year-old male associated with bilateral adrenocortical tumours. Physical findings and general laboratory data were unremarkable except for mild hypertension (158/90 mmHg) and impaired glucose tolerance. Endocrinological evaluation revealed the presence of autonomous cortisol secretion including unsuppressible serum cortisol by 8 mg dexa...
Previous studies ( 1 ) have shown that the specific alpha-ketolic steroid metabolites found in the urine after administration of a known alphaketolic steroid reflect, to a limited extent, the nature of the precursor. With this study as a baseline, we have determined the major urinary alphaketolic steroid metabolites found after intravenous infusion of human subjects with ACTH, and some of those...
