We aimed to assess the usefulness of pre-contrast Hounsfield unit (HU) and mass size on computed tomography to differentiate adrenal mass found incidentally in oncologic patients.


From 2000 to 2012, 131 oncologic patients with adrenal incidentaloma were reviewed retrospectively. Receiver operating characteristic (ROC) curves were applied to determine the optimal cut-off value of the mean HU and size for detecting adrenal metastasis.


The median age was 18 years, and 80 patients were male. The initial mass size was 18 mm, and 71 (54.2%) of these were on the left side. A bilateral adrenal mass was found in 11 patients (8.4%). Biochemically functional masses were observed in 9.2% of patients. Thirty-six out of 119 patients with nonfunctional masses underwent adrenalectomy, which revealed metastasis in 13. The primary cancers were lung cancer (n=4), renal cell carcinoma (n=2), lymphoma (n=2), hepatocellular carcinoma (n=2), breast cancer (n=1), and others (n=2). The area under the curve for the size and HU for clinically suspicious metastasis were 0.839 (95% confidence interval [CI], 0.761 to 0.900; P<0.001) and 0.959 (95% CI, 0.898 to 0.988; P<0.001), respectively. The cut-off value to distinguish between metastasis and benign masses were 22 mm for size and 20 for HU.


ROC curve results suggest that pre-contrast HU >20 can be used as a diagnostic reference to suggest metastasis in oncologic patients with adrenal masses.

AbstractAbstract PDF
Ectopic adrenocorticotropic hormone (ACTH) syndrome is mostly associated with neuroendocrine tumors and small cell carcinoma of the lung. This syndrome of prostate cancer is rare and has been reported in only a few cases. We report a patient with ectopic ACTH production associated with metastatic prostate cancer. A 70-year-old patient with metastatic prostate cancer was admitted to our hospital with septic shock. He had a history of hormonal therapy and transurethral prostatectomy. Adrenocortical function was checked due to consistent fever and poor general condition, which revealed markedly increased levels of basal plasma ACTH and serum cortisol. The patient did not present typical signs of the Cushing's syndrome, however, hypokalemia and a history of hypertension were found. He died in days as a result of multi-organ failure. On pathology, the prostatectomy specimen showed a tumor composed of mixed populations of adenocarcinoma and small cell carcinoma. The tumor cells in the small cell component were positive for chromogranin and ACTH. Although neuroendocrine differentiation in prostate cancer is rare, etopic ACTH production should be considered in patients with prostate cancer as well as in clinical features of ACTH hypersecretion.

AbstractAbstract PDF
Bile acids were important for the regulation of cholesterol homeostasis. Thyroid hormone increased the expression of CYP7A1 (cholesterol 7alpha-hydroxylase), catalyzing the first step in the biosynthesis of bile acids. However, the effect of thyroid hormone on bile acid export has not been previously assessed. The principal objective of this study is to evaluate the effects of thyroid hormone on the bile salt export pump (BSEP). METHODS: Thyroid hormone, T3 (1 mg/g) was administered to male mice via intraperitoneal injection. After 6 hours and 5 days of T3 treatment, we measured serum total and LDL cholesterol and hepatobiliary bile acid concentrations. We assessed the changes associated with bile acid synthesis and transport. In order to evaluate the direct effect of thyroid hormone, we assessed the changes in the levels of BSEP protein after T3 administration in human hepatoma cells. RESULTS: Serum total and LDL cholesterol were reduced and hepatobiliary bile acid concentrations were increased following T3 treatment. Expressions of Cyp7a1 and BSEP mRNA were increased following T3 treatment. The levels of the BSEP protein in the mouse liver as well as in the human hepatoma cells were increased after T3 treatment. CONCLUSION: Thyroid hormone can regulate LDL cholesterol metabolism. It increases bile acid synthesis and the excretion of bile acids via increased BSEP expression.

AbstractAbstract PDF
The objective of this study is to demonstrate the relationship between the volume of a parathyroid adenoma and the preoperative biochemical parameters in patients undergoing surgery for primary hyperparathyroidism. METHODS: The medical records of 68 patients who underwent a parathyroidectomy for a single parathyroid adenoma were retrospectively reviewed. The volume of the adenoma was estimated using its measured size and a mathematical formula. The correlation between the volume of the parathyroid adenoma and the preoperative laboratory data was assessed. RESULTS: There were no correlations between the estimated volume of the adenoma and the serum calcium, alkaline phosphatase and parathyroid hormone levels. However, the volume of the adenoma was associated with the preoperative level of serum phosphorus. After excluding 5 adenomas with cystic degeneration, a positive correlation was noted between the adenoma volume and the preoperative levels of alkaline phosphatase and parathyroid hormone. CONCLUSION: The preoperative serum levels of calcium, alkaline phosphatase and parathyroid hormone are of limited use to predict the volume of the parathyroid adenoma in patients with a single parathyroid adenoma. We suggest that the absence of a correlation between the volume of the adenoma and the biochemical parameters can be attributed to the cystic degeneration of the adenomas.
