The high complexity of pediatric reference ranges across age, sex, and units impairs clinical application and comparability of steroid hormone data, e.g., in congenital adrenal hyperplasia (CAH). We developed a multiples-of-median (MoM) normalization tool to overcome this major drawback in pediatric endocrinology.. Liquid chromatography tandem mass spectrometry data comprising 10 steroid hormones representing 905 controls (555 males, 350 females, 0 to > 16 years) from 2 previous datasets were MoM transformed across age and sex. Twenty-three genetically proven CAH patients were included (21-hydroxylase deficiency [21OHD], n = 19; 11β-hydroxylase deficiency [11OHD], n = 4). MoM cutoffs for single steroids predicting 21OHD and 11OHD were computed and validated through new, independent patients (21OHD, n = 8; adrenal cortical carcinoma, n = 6; obesity, n = 40).. 21OHD and 11OHD patients showed disease-typical, easily recognizable MoM patterns independent of age, sex, and concentration units. Two single-steroid cutoffs indicated 21OHD: 3.87 MoM for 17-hydroxyprogesterone (100% sensitivity and 98.83% specificity) and 12.28 MoM for 21-deoxycortisol (94.74% sensitivity and 100% specificity). A cutoff of 13.18 MoM for 11-deoxycortisol indicated 11OHD (100% sensitivity and 100% specificity).. Age- and sex-independent MoMs are straightforward for a clinically relevant display of multi-steroid patterns. In addition, defined single-steroid MoMs can serve alone as predictors of 21OHD and 11OHD. Finally, MoM transformation offers substantial enhancement of routine and scientific steroid hormone data exchange due to improved comparability.

Urinary steroid profiling (USP) was studied using high-performance liquid chromatography (HPLC) and gas chromatography-mass spectrometry (GC-MS) methods in 108 patients with adrenocortical adenoma (ACA) and in 31 patients with adrenocortical carcinoma (ACC). Thirteen ACC and Cushing's syndrome (ACC-CS) patients had two types of USP as well as 18 ACC patients without hypercortisolism. These four types differed by androgen and glucocorticoid secretion of the adrenal cortex. Fifteen main ACC features were observed by GC-MS. Urinary excretion of dehydroepiandrosterone (DHEA) was increased in 67.7 % of ACC patients and tetrahydro-11-deoxycortisol (THS) in 74.2 %. By combination of the following parameters: THS >900 μg/24 h and/or DHEA >1500 μg/24 h with ratios of 3α,16,20-pregnentriol/3β,16,20-pregnentriol (3α,16,20dP3/3β,16,20dP3) less than 6.0 and 3α,17,20dP3/3β,17,20dP3 less than 9.0 and the detection of "non-classical" 5-en-pregnens, not found in ACA and healthy persons, 100 % sensitivity and specificity of ACC and ACA differential diagnosis were achieved. Features of 21-hydroxylase and 11β-hydroxylase deficiency were observed by GC-MS in 32.2 and 61.3 % of the ACC patients, respectively. Additional features for ACC-CS diagnostic were increased urinary excretion of 6β-hydroxycortisol, 18-hydroxycorticosterone, the sum (UFF + UFE) obtained by HPLC, tetrahydrocorticosterone, and the sum (THF + THE + allo-THF) obtained by GC-MS.

Radiological examination may unexpectedly reveal an adrenal mass. Current algorithms for differentiating between benign and malignant lesions mainly rely on size and densitometry on unenhanced CT, which have limited specificity. We examined the diagnostic value of urinary steroid profiling by gas chromatography/mass-spectrometry (GC/MS) in differentiating between benign and malignant adrenal tumors. A retrospective study in two referral centers for patients with adrenal disease was performed. All urinary steroid profiles ordered for evaluation of an adrenal tumor between January 2000 and November 2011 were examined. Patients were diagnosed with adrenal cortical carcinoma (ACC), adrenal cortical adenoma (ACA), or other adrenal mass. Results of hormonal measurements, imaging studies, pathology reports, and clinical outcome were retrieved from medical records. The diagnostic value of individual urinary steroid metabolites was determined by receiver operating characteristics analysis. Cut-off values were compared to reference values from an age and gender-standardized population of healthy controls. Eighteen steroid metabolites were excreted in significantly higher concentrations in patients with ACC (n = 27) compared to patients with ACA (n = 107) or other adrenal conditions (n = 18). Tetrahydro-11-deoxycortisol (THS) at a cut-off value of 2.35 μmol/24 h differentiated ACC from other adrenal disorders with 100% sensitivity and 99% specificity. Elevated urinary excretion of THS was associated with a very high sensitivity and specificity to differentiate between an ACC and a benign adrenal mass. Urinary steroid profiling might be a useful diagnostic test for the evaluation of patients with an adrenal incidentaloma.

Long-term follow-up studies revealed that patients with subclinical hypercortisolism (SH) due to adrenocortical adenomas have an increased incidence of cardiovascular diseases and mortality. No studies have yet investigated the steroid profile and its implications in patients with SH.. The objective of the study was to analyze the steroid profile by liquid chromatography-tandem mass spectrometry in sera from patients with unilateral adrenocortical adenomas.. This was a cross-sectional study.. The study was conducted at an outpatient clinic.. Patients with adrenocortical adenomas (nonsecreting, n = 66; SH, n = 28) and 188 age- and sex-matched controls drawn from the general population participated in the study.. Cortisol, 21-deoxycortisol, 11-deoxycortisol, 17-hydroxyprogesterone, androstenedione, dehydroepiandrosterone, T, progesterone, 11-deoxycorticosterone, and corticosterone in the basal condition and after a 1-24 ACTH test, and clinical data were measured.. Patients with SH showed lower basal and 1-24 ACTH-stimulated levels of dehydroepiandrosterone and androstenedione than those with nonsecreting adenomas and controls. T was also lower in SH females. Receiver-operating characteristic curves showed that androgens had good accuracy in predicting SH (sensitivity and specificity were 71% and 76% for dehydroepiandrosterone and 69% and 61% for androstenedione, respectively). Increased cortisol and reduced dehydroepiandrosterone levels were independently associated with increased waist circumference. Cortisol was also independently associated with increased number of cardiovascular risk factors in SH patients. After 1-24 ACTH stimulation, the SH patients also showed increased production of 21-deoxycortisol and 11-deoxycorticosterone.. Liquid chromatography-tandem mass spectrometry steroid profile performed for the first time in sera from patients with adrenocortical adenomas showed impaired secretion of several steroids in SH patients. This fingerprint can help in better characterizing the functional status of these tumors.

Adrenocortical carcinoma (ACC) is a very rare malignant tumor with poor prognosis. To gain insight into the pathogenic significance of ACC, we studied clinicopathological features and gene expression profile in ACC. We analyzed five ACC cases (two men and three women) with the median age of 45-year-old who underwent adrenalectomy at our institute. Endocrine studies revealed that two cases had subclinical Cushing's syndrome (SCS) and one with concomitant estrogen-secreting tumor, while the rest of three cases had non-functioning tumors. Analysis of urinary steroids profile by gas chromatography/mass spectrometry showed increased metabolites of corticosteroid precursors, such as 17-OH pregnenolone, 17-OH progesterone, dehydroepiandorosterone (DHEA), and 11-deoxycortisol in all five cases. The pathological diagnosis of ACC was based on Weiss's criteria with its score ≥ 3. The mean size of the resected tumors was 87 mm and Ki67/MIB1 labeling index, a proliferative marker, was 3-27%. Immunohistochemical analysis revealed a disorganized expression of several steroidogenic enzymes, such as 3β-hydroxysteroid dehydrogenase, 17α-hydroxylase, and DHEA-sulfotransferase. Among several genes determined by RT-PCR, insulin-like growth factor (IGF)-II mRNA was consistently and abundantly expressed in all 5 tumor tissues. Postoperatively, two cases with SCS developed local recurrence and liver metastasis. The present study suggests that the disorganized expression of steroidogenic enzymes and the overexpression of IGF-II by the tumor are hallmarks of ACC, which could be used as biochemical and molecular markers for ACC.

An examination of 145 patients with incidentalomas and 195 women with virale syndrome has shown that 20% of patients with incidentalomas and 23.1% of patients with steroidogenesis have disorders of the adrenal steroidogenesis characteristic of the obliterated form of congenital hyperplasia of the adrenal cortex (CHAC) with a defect of 11beta-hydroxylase on the basis of the following biochemical criteria: the elevation in blood of the basal levels of 11-desoxycortisole and 11beta-desoxycorticosterone, decreased excretion of free cortisole with urine, lower indices of hydrocortisole/cortisone in blood and free cortisole/free cortisone in urine, in the test with corticotropin - elevation in blood of the level of 11-desoxycortisole and 11-desoxycorticosterone, decreased relationships cortisole/11-desoxycortisole and cortisole/cortisone and lower growth of the levels of corticosterone and cortisole. The data obtained suggest that long-standing obliterated form of CHAC with a defect of 11beta-hydroxylase might be the cause of the formation of certain incidentalomas.

Adrenocortical carcinoma is a rare malignancy in children, with a high mortality. Little is known about long-term outcome, especially in infants treated with mitotane. We report the successful long-term outcome of a case of metastatic adrenocortical carcinoma presenting in infancy treated with surgical resection and mitotane. The patient presented at 2 months of age with Cushing's syndrome, a large adrenal mass, and elevated adrenal steroid levels. The tumor was removed surgically. Intraoperative findings included an adrenal tumor (confirmed malignant pathologically) invading the adrenal vein and vena cava. After surgery he was treated with mitotane at a dose of 2 g/d. Six months after surgery 11-deoxycortisol levels increased, and a computed tomography scan showed a pulmonary metastasis. Mitotane was increased to 2.5 g/d, and the metastasis was removed surgically. Plasma mitotane levels ranged 10-15 micro g/ml. Tumor markers remained normal, and mitotane was discontinued at 18 months. During therapy the patient's somatic growth was poor. His motor and speech development was delayed. After mitotane was discontinued he demonstrated catch-up growth. This case shows successful long-term outcome and recovery from the toxic effects of mitotane.

Corticosteroid 11 beta-hydroxylation is catalyzed by 11 beta-hydroxylase and aldosterone synthase. Using plasma steroid ratios, the level of this process in patients with glucocorticoid-suppressible hyperaldosteronism (GSH) was compared with that in unaffected control subjects and patients with Conn's syndrome. Based on both 11-deoxycortisol/cortisol (S:F) and 11-deoxycorticosterone/corticosterone (DOC:B) ratios, patients with GSH showed impaired resting 11 beta-hydroxylase activity. In GSH, but not in the other groups, the S:F ratio was significantly correlated with the basal plasma aldosterone concentration. ACTH infusion increased the S:F ratio in all of these patient groups, suggesting a common partial deficiency. The results also indicate that 11 beta-hydroxylation may be rate limiting in normal subjects. In control subjects and patients with Conn's syndrome, the DOC:B ratio was not affected by ACTH. However, in GSH patients, this ratio fell markedly, indicating an increased efficiency of 11 beta-hydroxylation of DOC (but not S). This may be due to the activation by ACTH of the zona fasciculata chimeric aldosterone synthase characteristic of this disease. Plasma aldosterone, corticosterone, and DOC concentrations appeared to be more sensitive to ACTH in GSH than in the other groups. The defect in 11 beta-hydroxylation in GSH accounts for the increased levels of DOC reported in this condition and may contribute to the phenotype variability.

A 28-year old female patient with virilization due to left adrenocortical adenoma was studied. The patient had clinical features of hyperandrogenism such as hirsutism and a low pitched voice, but not of hypercorticoidism. Plasma testosterone and dehydroepiandrosterone-sulfate (DHEA-S) were high. Although the basal plasma cortisol concentration and urinary excretion of 17-hydroxycorticosteroids (17-OHCS) were within the normal range, the absence of diurnal variation in plasma cortisol and loss of suppressibility by dexamethasone suggested constitutive secretion of cortisol by the tumor. Inappropriate cortisol secretion was also supported by blunted ACTH response to provocative stimuli. After successful removal of the left adrenal tumor, such endocrinological abnormalities were all normalized. Immunohistochemical analysis revealed that tumor cells were positively stained for C21 hydroxylase cytochrome P-450 (P-450C21) and P-450(11) beta which convert 17-hydroxy (OH) progesterone to cortisol as well as P-450SCC, 3 beta-hydroxysteroid dehydrogenase and P-450(17) alpha which are involved in testosterone biosynthesis. These findings suggest that adrenocortical adenoma secretes predominantly testosterone and constitutively cortisol in a young woman patient with virilization.

To analyse the clinical and biochemical effects of metyrapone in the treatment of Cushing's syndrome.. An evaluation of the standard clinical practice at one institution.. Ninety-one patients with Cushing's syndrome: 57 pituitary-dependent Cushing's disease, 10 adrenocortical adenomas, six adrenocortical carcinomas and 18 ectopic ACTH syndrome.. The acute response to metyrapone was assessed by measuring cortisol, 11-desoxycortisol and ACTH at 0, 1, 2, 3, 4 hours after a test dose of 750 mg of metyrapone. The longer-term effect of metyrapone was judged by measuring serum cortisol at 0900, 1200, 1500, 1800, 2100 and sometimes 2400 h and calculating a mean.. A test dose of 750 mg of metyrapone decreased serum cortisol levels within 2 hours in all groups of patients and this effect was sustained at 4 hours. At the same time, serum 11-desoxycortisol levels increased in all patients, while plasma ACTH increased in patients with pituitary Cushing's disease and the ectopic ACTH-syndrome. Fifty-three patients with Cushing's disease were followed on short-term metyrapone therapy (1 to 16 weeks) before other more definitive therapy. Their mean cortisol levels (median 654 nmol/l, range 408-2240) dropped to the target range of less than 400 nmol/l in 40 patients (75%) on a median metyrapone dose of 2250 mg/day (range 750-6000). Metyrapone was given long term in 24 patients with Cushing's disease who had been given pituitary irradiation, for a median of 27 months (range 3-140) with adequate control of hypercortisolaemia in 20 (83%). In 10 patients with adrenocortical adenomas and six with adrenocortical carcinomas, metyrapone in a median dose of 1750 mg/day (range 750-6000) reduced their mean cortisol levels (median 847 nmol/l, range 408-2000) to less than 400 nmol/l in 13 patients (81%). In 18 patients with the ectopic ACTH-syndrome the 'mean cortisol levels', obtained from five or six samples on the test day (median 1023 nmol/l, range 823-6354) were reduced to less than 400 nmol/l in 13 patients (70%), on a median dose of 4000 mg/day (range 1000-6000). Reduction of cortisol levels was clearly associated with clinical and biochemical improvement. The medication was well tolerated. Transient hypoadrenalism and hirsutism were unusual but were the most common side-effects.. In our experience metyrapone remains a most useful agent for controlling cortisol levels in the management of Cushing's syndrome of all types.

A serum steroid profile was determined in 11 patients with adrenocortical carcinoma, 5 with adrenocortical adenoma and 10 healthy controls. Seven of the patients with carcinoma had different forms of endocrine symptoms, and of those with adenoma 3 had Cushing's syndrome and 2 primary hyperaldosteronism. Sulphated steroids dominated in serum from both patients and controls, whereas the levels of free and glucuronated steroids were low. All patients with adrenocortical carcinoma had increased levels of sulphated pregn-5-ene-3 beta-ol-20-one (pregnenolone) and pregn-5-ene-3 beta,20 alpha-diol compared with healthy controls and patients with adrenocortical adenoma. Serum levels of 11-deoxycortisol and/or its glucuronated metabolite tetrahydro-11-deoxycortisol were clearly elevated in 8 of the patients with carcinoma. The results are in agreement with those previously found for conjugated urinary steroids in patients with adrenocortical carcinoma. Thus, an impaired function or deficiency of 3 beta-hydroxysteroid dehydrogenase/delta isomerase and in some cases also of 11 beta-hydroxylase could explain the findings. The serum levels of sulphated pregnenolone and/or pregn-5-ene-3 beta,20 alpha-diol, possibly together with free 11-deoxycortisol seem to be useful for preoperative discrimination between malignant and benign adrenocortical tumours.

The urinary steroid profile was determined in 24 patients with adrenocortical carcinoma. Seventeen of the patients had Cushing's syndrome, virilization or feminization, and 7 had no signs of endocrine disease. Seven of the 11 patients still alive are free of disease, after a follow-up period of 5-75 months. The steroid profile varied widely between the patients with adrenocortical carcinoma. Patients with Cushing's syndrome had increased levels of cortisol metabolites and those with virilism had raised excretion of androgen metabolites. Six of the patients with adrenocortical carcinoma showed normal values of these metabolites. In 23 of the 24 patients the excretion of 3 beta-hydroxy-5-ene steroids and/or metabolites of cortisol precursors, such as tetrahydro-11-deoxycortisol, were significantly increased, compared with healthy controls or patients with adrenal adenomas. These findings suggest a relative deficit or low activity of 3 beta-hydroxysteroid dehydrogenase/delta isomerase and/or 11 beta-hydroxylase in tumour tissue. In the single patient where the steroid profile failed to indicate malignancy, hypercortisolism was seen and the tumour mass was small. The steroid excretion normalized after radical surgery and decreased in patients responding to chemotherapy. During recurred disease the metabolites of 3 beta-hydroxy-5-ene steroids and/or cortisol precursors increased, but in some patients the excretory pattern then was different from that seen before treatment.

We present nine cases of primary adrenocortical carcinoma, collected in our department of medicine and endocrinology over 25 years. In our patients, the most dependable tumor marker was urinary excretion of tetra-hydro-ll-deoxycortisol (THS), and elevated values were found in all cases where it was determined. In addition to surgical treatment, medication with o,p'-DDD was found to be of value for some of the patients. Median tumor weight was 487 g (118-2,085 g). Prognosis is difficult to predict. Median survival time after diagnosis was 34 months, but varied from three to 266 months.

A 47-year-old female presented with hypertension, hypokalaemia, low plasma renin, high plasma aldosterone and was found to have a left adrenal tumour 4 cm in diameter by computerized tomography. Detailed biochemical studies showed high plasma levels of 11-deoxycorticosterone and corticosterone in addition to aldosterone and 18-hydroxycorticosterone. Basal 11-deoxycorticosterone levels were particularly high. Corticosterone, 18-hydroxycorticosterone and aldosterone concentrations were abnormally sensitive to infusions of ACTH and angiotensin II. Plasma cortisol and assays for sex hormones were normal although there was evidence that cortisol derived from the neoplasm. At operation a well-differentiated adrenocortical carcinoma weighing 50 g (56 X 30 X 36 mm) was removed. There was no evidence of metastases following surgery. Adrenal function returned to normal. Review of the literature suggests that adrenocortical carcinoma should be suspected in patients who otherwise have typical features of Conn's syndrome, but whose tumours are more than 3 cm in diameter. Measurement of steroids such as 11-deoxycorticosterone in addition to aldosterone is recommended since abnormally high values may also help to distinguish between hyperaldosteronism due to adenoma and carcinoma. Previously reported cases of isolated aldosterone production by a carcinoma cannot be substantiated.

In search for a biochemical marker to differentiate between adrenocortical carcinoma (AC) and adenoma (AA), plasma levels of the following steroids were studied preoperatively and postoperatively: 11-deoxycorticosterone (DOC), corticosterone (B), 11-deoxycortisol (S), and cortisol (F). Levels were measured by Sephadex LH-20 chromatography and specific radioimmunoassays. The subjects included eight children ages 2 years, 5 months to 9 years, 10 months. There were three girls and 5 boys with pseudoprecocious puberty due to adrenocortical tumors (histologically, four were AC and four, AA). The preoperative showed that DOC and S levels were elevated in all patients, F levels were elevated in four of eight children when compared with age-matched controls, whereas B was normal. Postoperatively, all levels returned to normal. The ratios of B/DOC and F/S as an index of adrenal 11 beta-hydroxylase activity were calculated. The preoperative ratios of B/DOC were markedly decreased in all patients with AC compared to controls (7.7,4.1,5.9,1.9 versus 23.5, median), but normal in three of four patients with AA (16.2, 29.6, 16.1). The F/S ratios were significantly lower in AC and AA when compared with controls. The data indicate a deficiency in 11 beta-hydroxylation in cases of adrenocortical tumors. Despite a still limited number of patients, the decreased B/DOC ratios may possibly indicate malignancy and could be helpful in distinguishing by biochemical means between benign and malignant adrenocortical tumors.

A case of adrenal carcinoma with Cushing's syndrome was presented. Endocrinological and morphological investigations disclosed the presence of a functional adrenal carcinoma. This case was characterized by its unusual urinary 17-ketosteroid (17-KS) fractionation, i.e. a marked elevation of 17-KS was accompanied by the increments of etiocholanolone, but not of dehydroepiandrosterone (DHEA) or androsterone. Measurements of the plasma adrenocorticosteroids revealed normal DHEA and DHEA-S (sulfate) levels, moderately increased 17-OH-pregnenolone, and markedly increased (less than 100 times the normal) 11-deoxycortisol (cpd S). Therefore, it seems plausible that the normal urinary DHEA level in this patient would have occurred as a result of remarkably low C17-20 lyase activity sufficient to hamper DHEA production, and that markedly increased etiocholanolone might possibly have been converted from cpd S as well as from DHEA and androstenedione through 5 beta-reduction.

Data are presented concerning a case of female pseudohermaphroditism of unknown etiology. The child was born with labioscrotal fusion and clitoromegaly. From the age of 5 to the age of 25 there was no clinical evidence of a hormonal abnormality. At the age of 25 the patient presented with masculinization and Cushing's syndrome, and a left adrenal tumor was removed. The patient was restudied at the age of 29, when 21-hydroxylase deficiency was excluded. Other types of congenital adrenal hyperplasia are considered unlikely. The possible relationship between the ambiguous genitalia present at birth and the virilizing tumor diagnosed at the age of 25 is analyzed.

Differentiating the cause of Cushing's syndrome traditionally has depended upon measuring the response of 24-hour urine samples of cortisol or glucocorticoid metabolites to the high-dose (8 mg per day) dexamethasone test. The metyrapone test, however, is more convenient because it is a shorter test and requires the obtainment of serum samples, which can be collected more simply and more reliably than 24-hour urine samples. The usefulness of these two tests has not been adequately evaluated in a large series of patients with Cushing's syndrome. This study prospectively evaluated the accuracy of the dexamethasone and metyrapone tests in determining the cause of Cushing's syndrome in a series of 25 unselected patients. The diagnostic accuracy of these tests was calculated as follows: diagnostic accuracy = true positives and true negatives/study population X 100. Results of this study demonstrated that the metyrapone test was more accurate than the dexamethasone test in differentiating Cushing's disease from adrenocortical neoplasm (diagnostic accuracy, 100 percent versus 81 percent). All patients with Cushing's disease had a normal postmetyrapone 11-deoxycortisol concentration (greater than 10 micrograms/dl), while all patients with adrenocortical neoplasm had a suppressed 11-deoxycortisol concentration (less than 10 micrograms/dl). Thus, this study demonstrates that the metyrapone test is superior to the high-dose dexamethasone test in the differential diagnosis of Cushing's syndrome.

An adrenal tumor was discovered fortuitously in a patient with no clinical features of Cushing's syndrome. On adrenal imaging, there was good uptake in the nodule but no visualization of the contralateral adrenal. The latter was seen, however, in a second scan performed under ACTH treatment. In the hormone assessment, basal cortisol and 17-hydroxycorticoids were normal and cortisol diurnal variation was near normal, but a dexamethasone suppression test and ACTH responses to metyrapone and insulin hypoglycemia were abnormal. Eight months after excision of a spongiocytic-type adenoma, the remaining adrenal was visible on scintigram and the hormonal tests were normal. This pattern suggests that the clinical Cushing's syndrome but enough to suppress partially ACTH and, consequently, visualization of the contralateral gland.

Four post-menopausal women had Cushing's syndrome due to adrenal cortical carcinomas. Comprehensive analyses of blood and urinary steroids showed that although the steroid profiles differed between patients, the pattern in each patient remained almost constant as the disease progressed, or remitted due to therapy. Elevations of serum testosterone and oestradiol were commensurate with the extent of virilisation, and the urinary output of aldosterone was associated with the severity of hypertension. A new finding was that all had substantially increased urinary free deoxycorticosterone. Complete surgical removal of the primary tumours was impossible but when most of the tumour tissue was removed, full clinical and biochemical remissions were obtained for a short time in 2 patients. One patient obtained a clinical and biochemical remission from op'DDD. In another patient the drug caused reduction both in blood pressure and in urinary aldosterone excretion, but there were unpleasant side effects. A third patient could not tolerate op'DDD. Metyrapone therapy produced neither clinical nor biochemical improvement in 3 patients. The mean duration of survival was 17 months after the first symptoms and 10 months from the date of operation. Despite advances in drug therapy, adrenal cortical carcinoma remains a lethal disease. Biochemical screening of multiple steroids offers a means of early diagnosis and disease monitoring. Extensive surgical removal of the tumour offers the best chance of a clinical and biochemical remission.

The synthesis of glucocorticoids and mineralocorticoids in vitro was studied in an adrenocortical carcinoma after alblation from an 11.5-year-old boy. This patient had been unsuccessfully treated with high doses of o,p'-dichlorodiphenyldichloroethane (o,p'-DDD) and aminoglutethimide. These in-vitro results were compared with those obtained with another adrenocortical carcinoma removed from a 26-year-old woman who had received no preoperative treatment. The sensitivity of these adrenocortical carcinomas to o,p'-DDD, aminoglutethimide and 2-(p-aminophenyl)-2-phenylethylamine (SKF 12185) was investigated. Synthesis of cortisol (47%) and corticosterone (45%) in control incubations showed that 11 beta-hydroxylase activity was not affected by the treatment. This explains the raised level of plasma cortisol in the treated child. All three compounds inhibited both 11 beta-hydroxylase and 18-hydroxylase activities up to 95%, depending on the inhibitor. This study shows (a) an inhibitory effect of o,p'-DDD on the steroidogenesis of an adrenocortical carcinoma in vitro, an effect not previously reported in man or laboratory animals, and (b) the in-vitro efficacy of o,p-DDD and aminoglutethimide on corticosteroidogenesis by a carcinoma unresponsive to treatment in vivo. This discrepancy between data obtained in vivo and in vitro could possibly be explained by either an insufficient ratio of ingested dose: tumour mass, or a malabsorption of the drugs in this patient.

Two adult men with feminizing adrenal cortical carcinoma had measurements of their 24-h plasma corticosteroid and gonadotropin patterns as well as 24-h mean hormone levels of estradiol, estetrol, 11-desoxycortisol, DHEA-S, DHEA and testosterone. Cortisol, 11-desoxycortisol and estrogen production rates were also measured. The 24-h corticosteroid patterns showed preservation of the normal 24-h episodic and circadian patterns, albeit at higher levels. The cortisol production rates were markedly elevated despite only moderate elevation of the 24-h mean cortisol level. There were elevated plasma 11-desoxycortisol levels and a markedly elevated 11-desoxycortisol production rate in one patient and THS excretion in the other. The plasma estradiol levels, urinary excretion and production rates were markedly elevated. In addition, there was a decrease in the specific activity of estriol compared with estrone and estradiol as well as measurable levels of estetrol in both patients. These latter observations coupled with the urinary immunoassayable hCG in one patient suggest that these tumors may be functioning like trophoblastic tissue. The possibility that estetrol may serve as an additional marker for tumors of trophoblastic origin is of additional interest.
