Context Current evidence on determinants of quality of life (QoL) in patients with adrenal insufficiency (AI) is limited. Objective This work aimed to identify the determinants of QoL in different subtypes of AI. Methods This multicenter cross-sectional survey study was conducted using a patient-centered questionnaire, the Short Form-36. Results Of 529 participants, 223 (42.2%) had primary AI, 190 (35.9%) had secondary AI, and 116 (21.9%) had glucocorticoid-induced AI. Median age was 58 years (interquartile range: 43-68 years) and 342 (64.8%) were women. In multivariable analyses, patients were more likely to report worse physical scores if they were women (odds ratio [OR]: 3.3; 95% CI, 1.8-6.0), had secondary AI or glucocorticoid-induced AI (OR: 2.5; 95% CI, 1.4-4.3), had shorter duration of AI (OR: 2.0; 95% CI, 1.1-3.6), were treated with more than 25 mg hydrocortisone equivalent daily (OR: 2.3; 95% CI, 1.2-4.6), had more comorbidities related to glucocorticoid excess (OR: 2.3; 95% CI, 1.3-4.0), reported a higher financial burden from AI (OR: 2.1; 95% CI, 1.3-3.6), and reported difficulties with AI management (OR: 2.5; 95% CI, 1.2-5.2). Women (OR: 2.1; 95% CI, 1.08-4.0), shorter duration of AI (OR: 2.4; 95% CI, 1.4-4.3), higher financial burden (OR: 2.3; 95% CI, 1.3-4.0), difficulties with AI management (OR: 2.6; 95% CI, 1.4-4.9), and lack of family support (OR: 9.1; 95% CI, 2.3-33.3) were associated with worse mental component scores. Conclusion In patients with AI, QoL could be improved by addressing certain determinants, such as avoiding GC overreplacement, providing in-depth education on self-management, offering more comprehensive insurance coverage, and ensuring better family support.

Context Adrenocortical carcinoma (ACC) is a rare endocrine malignancy that affects patients across the age spectrum. Although the overall survival in patients with ACC is poor, there is significant heterogeneity in terms of outcomes, presentation, and underlying genetic drivers. Evidence Acquisition This review is based on the evidence collected from primary research studies, expert reviews, and published guidelines. The studies were identified through PubMed search with key words “adrenocortical carcinoma,” “prognosis,” “pathology,” and “genetics.” The PubMed search was complemented by authors’ expertise, research, and clinical experience in the field of ACC. Evidence Synthesis Identification of biomarkers has been critical to gain better insight into tumor behavior and to guide therapeutic approach to patients. Tumor stage, resection status, and Ki67 are pathological tumor characteristics that have been identified as prognosticators in patients with ACC. Cortisol excess also correlates with worse prognosis. Clinical and histopathological characteristics help stratify patient outcomes, yet still up to 25% of patients have a different outcome than predicted. To bridge this gap, comprehensive genomic profiling studies have characterized additional profiles that correlate with clinical outcomes. In addition, studies of clinically applicable molecular markers are under way to further stratify outcomes in patients with ACC tumors. Conclusions Clinical predictors in combination with pathological markers play a critical role in the approach to patients with ACC. Recent advances in genetic prognosticators will help extend the stratification of these tumors and contribute to a personalized therapeutic approach to patients with ACC.

18F-fluorodeoxyglucose positron emission tomography computed tomography (FDG PET/CT) is frequently used for evaluation of indeterminate adrenal nodules. The objective of this study was to evaluate the diagnostic performance of FDG PET/CT in distinguishing benign adrenocortical adenomas (ACA) from adrenocortical carcinoma (ACC). We identified 139 patients in our institution who completed both FDG PET/CT and adrenal biopsy or adrenalectomy from 2001 to 2019 using the institutional Electronic Medical Record Search Engine (EMERSE). Patients with adrenal pathology revealing non-adrenocortical tumors were excluded. The imaging characteristics of ACAs were compared with ACCs. Sixteen patients with ACAs and 50 patients with ACC were identified; of the latter, 30 were excluded, because FDG PET/CT imaging was completed after adrenalectomy. The average age of the ACC vs. ACA group was 48±14 and 52±17 years, respectively, with a gender composition of 35% and 25% men, respectively. All 20 patients with ACC had FDG avid lesions, defined by imaging report and increased ratio of adrenal tumor maximum standardized uptake value (SUVmax) to hepatic parenchymal average SUV (SUVmean) of greater than 2.5. Among those with ACAs, 11 had positive, 1 had mildly positive, 3 had indeterminate, and 1 had negative FDG PET/CT findings according to the report. Ratio of adrenal SUVmax to hepatic SUVmean was greater in ACC compared to ACA (13.5 versus 1.6, respectively, p = 0.13), but did not reach statistical significance, likely due to the small sample size and unavailability of SUV ratios for all lesions. Our study identified a large number of ACAs that were deemed FDG avid but without adrenal SUVmax to hepatic SUVmean ratio of greater than 2.5. Although the sensitivity, and therefore the negative predictive value, of FDG PET/CT scan is excellent for the diagnosis of ACC, our data does not allow for the calculation of specificity. This is due to the selection bias inherent in our patient population referred for evaluation of unusual adrenal masses, and the fact that ACAs with negative FDG PET/CT often do not undergo surgery or biopsy, and therefore pathology results are not available. Despite this limitation, our findings show that calculation of the ratio of adrenal SUVmax to hepatic SUVmean, rather than lesion SUVmax alone, helps for characterization of adrenal lesions as malignant vs. benign, and that a negative FDG PET/CT is valuable in excluding ACC.

Background: Aldosterone-producing adenoma (APA) is a major subtype of primary aldosteronism (PA) which is the most common cause of endocrine-related hypertension. The Endocrine Society clinical practice guideline suggests that young patients (< 35 years old) with a CT-detected adrenocortical adenoma and typical phenotype of PA may not need adrenal venous sampling prior to adrenalectomy. In recent years, aldosterone-driver somatic mutations have been identified in APA, and prevalence studies suggest potential effects of patient age and sex. However, the rare nature of early-onset PA has prevented a detailed study of the histologic characteristics and aldosterone-driver somatic mutations in adrenal tumors from these patients. Objective: To determine histologic and somatic mutation profile in early-onset APA. Methods: Fifty-five formalin-fixed paraffin-embedded (FFPE) adrenals from patients at the age of 35 years old or younger who underwent adrenalectomy at the participating centers were studied (45 women, 9 men, and 1 unknown sex). CYP11B2 immunohistochemistry (IHC)-guided tumor capturing was used to selectively obtain DNA from APA. Mutation status was determined either by Sanger sequencing or targeted next-generation sequencing. Results: CYP11B2 IHC identified APAs in all adrenal specimens. Solitary APAs were found in 53 adrenals. One adrenal had multiple APAs and one had a dominant CYP11B2-negative tumor and a smaller APA. In total, DNA from 57 APAs were sequenced. Two APAs were excluded from the analysis due to low sample quality. In 52 of the 55 APAs, somatic mutations were identified in one of the aldosterone-driver genes or CTNNB1 gene, encoding β-catenin. The most common genetic alteration was seen in KCNJ5 (37/55, 67%), followed by CACNA1D (7/55, 13%), ATP1A1 (3/55, 5%), CTNNB1 (3/55, 5%), and ATP2B3 (2/55, 4%). No sex difference in the prevalence of KCNJ5 mutation was observed in this age group. Conclusion: The majority of adrenals from early-onset PA patients had a solitary APA. Regardless of sex, the most common genetic cause of early-onset APA was somatic mutations in KCNJ5.

Most ovarian steroid cell tumors arise sporadically. However, they can also be observed as a rare manifestation of von Hippel Lindau disease. Here, we present a clinical, pathological and molecular characterization of a steroid cell tumor in a VHL patient. A 14 year old girl with molecularly confirmed diagnosis of VHL developed hirsutism and amenorrhea. Initial clinical hormonal evaluation was notable for elevated 17-OHP of 406ng/dl, androstenedione 275ng/dl, and testosterone 102ng/dl. In order to exclude congenital adrenal hyperplasia as a common cause of hirsutism in adolescents, ACTH stimulation was performed, but no increase in 17-OHP was observed. Anti Muellerian hormone, inhibin (INH) A and INH B were normal. Imaging revealed a bilobed 6cm left adnexal mass. The mass was resected en bloc via a left oophorectomy. Pathological evaluation showed multinodular steroid cell tumor with clear cytoplasm and delicate vascular meshwork. Immunoprofiling demonstrated positivity for inhibin and calretinin; while renal cell carcinoma markers were negative. All laboratory values normalized post-surgery. In addition to clinical measurements pre- and post-surgery, steroid profiles were evaluated by LC-MS/MS. Quantitative RT-PCR analysis showed robust tumor expression of enzymes facilitating the production of androgens, but not estrogens. Further preliminary analysis by exome sequencing confirmed the known germline pathogenic variant in VHL, but no additional obvious somatic driver mutations were identified. Interestingly, the NGS analysis of different specimens from the same tumor revealed multiple different single base pair variants in the VHL gene as a second hit. In summary, hirsutism in VHL patients should raise the suspicion for unusual ovarian tumors. In contrary to the usual theory of a monoclonal expansion after loss of the wt VHL allele, this tumor appeared to be oligoclonal as evidenced by different somatic VHL mutations. This could be either explained by initial parallel occurrence of several clones or that the VHL second hit is not an initial event, but the mutation instead supports tumor expansion following initial steps of tumorigenesis.
