Endocrine hypertension secondary to adrenal tumors: clinical course and predictive factors of clinical remission.

PURPOSE: Endocrinopathies constitute ~ 10% of secondary hypertension (SH) etiologies. Primary aldosteronism, pheochromocytoma (PHEO), and Cushing's syndrome are common causes. Early identification and treatment result in resolution/improvement of SH. The aim of this study was to characterize the clinical course, outcomes, and remission-associated prognostic factors of SH related to adrenal tumors. METHODS: Retrospective cohort study including patients with SH who underwent adrenalectomy from 2000 to 2019. Postoperative outcomes were analyzed. Remission was defined as normalization of blood pressure without drug use. RESULTS: Eighty-three patients with SH were included. Mean ± SD age was 38.8 ± 14.2 years and 75.9% were women. Diagnosis was PHEO in 35 patients (42.2%), aldosteronoma (APA) in 28 (33.7%), cortisol producing adenoma (CPA) in 16 (19.3%), and ACTH-dependent Cushing's in 4 (4.8%). Laparoscopic adrenalectomy was performed in 81 (97.6%) patients. Mean ± SD follow-up was 57.4 ± 49.6 months (range 1-232). Surgical morbidity occurred in 7.2% of patients and there was no mortality. Remission of SH occurred in 61(73.5%): 100% of ACTH-dependent Cushing's, 85.7% of PHEO, 68.8% of CPA, and 57.1% of APA. Biochemical phenotype and the combination of larger tumor size, number of antihypertensive drugs, male gender, older age, obesity, and preoperative SH for more than 5 years were associated with less likely clinical remission in patients with APA (p = 0.004), CPA (p < 0.0001), and PHEO (p < 0.0001). CONCLUSION: SH remission rates are 57-100% after adrenalectomy. Several prognostic factors could be used to predict SH control. Adrenalectomy provides good clinical outcome and must be considered a treatment option in all surgical candidates.

The "Quiet TED"-A Special Subgroup of Thyroid Eye Disease.

PURPOSE: Thyroid eye disease (TED) or Graves' orbitopathy starts with an active inflammatory stage (active disease) followed by resolution of inflammation and progression to a fibrotic, inactive stage. In our practice, we have encountered cases that have not had active disease despite presence of fibrotic sequelae and disease progression. We aim to delineate the clinical characteristic of this unique group of patients. METHODS: We conducted a single-center (Mayo Clinic Rochester) retrospective chart review of TED patients who throughout the course of their disease had only evidence for inactive TED, defined as clinical activity score <3. RESULTS: Median age in the cohort (n = 19) was 54 years (IQR 47-61). 58% had a prior diagnosis of Graves' disease (GD) before referral. 80% (n = 15) were euthyroid at the time of TED onset (median thyroid-stimulating hormone 1.7 mIU/L). The most common finding was diplopia (100%, n = 19) followed by proptosis (63%, n = 12). Interestingly the disease was asymmetric in 42% of cases. Overall median clinical activity score on presentation was 1 (IQR 0-1). Severity wise, 85% (n = 16) of patients were classified as moderate-to-severe during follow up. Orbital decompression was performed in only 1 case, while extraocular muscle surgery was performed in 13 cases. CONCLUSIONS: Quiet TED is a subgroup of TED patients that defies the classic disease paradigm. It presents primarily with diplopia and proptosis. Further evaluation of this group might identify useful insights in TED pathophysiology and help optimize therapeutic choices.

Impact of hypercortisolism on skeletal muscle mass and adipose tissue mass in patients with adrenal adenomas.

CONTEXT: Abdominal visceral adiposity and central sarcopenia are markers of increased cardiovascular risk and mortality. OBJECTIVE: To assess whether central sarcopenia and adiposity can serve as a marker of disease severity in patients with adrenal adenomas and glucocorticoid secretory autonomy. DESIGN: Retrospective cohort study. PATIENTS: Twenty-five patients with overt Cushing's syndrome (CS), 48 patients with mild autonomous cortisol excess (MACE) and 32 patients with a nonfunctioning adrenal tumour (NFAT) were included. METHODS: Medical records were reviewed, and body composition measurements (visceral fat [VAT], subcutaneous fat [SAT], visceral/total fat [V/T], visceral/subcutaneous [V/S] and total abdominal muscle mass) were calculated based on abdominal computed tomography (CT). RESULTS: In patients with overt CS, when compared to patients with NFAT, the V/T fat and the V/S ratio were increased by 0.08 (P < .001) and by 0.3 (P < .001); however, these measurements were decreased by 0.04 (P = .007) and 0.2 (P = .01), respectively, in patients with MACE. Total muscle mass was decreased by -10 cm2 (P = .02) in patients with overt CS compared to patients with NFAT. Correlation with morning serum cortisol concentrations after dexamethasone suppression testing revealed that for every 28 nmol/L cortisol increase there was a 0.008 increase in V/T (P < .001), 0.02 increase in the V/S fat ratio (P < .001) and a 1.2 cm2 decrease in mean total muscle mass (P = .002). CONCLUSIONS: The severity of hypercortisolism was correlated with lower muscle mass and higher visceral adiposity. These CT-based markers may allow for a more reliable and objective assessment of glucocorticoid-related disease severity in patients with adrenal adenomas.

Papillary Thyroid Carcinoma (PTC) in Children and Adults: Comparison of Initial Presentation and Long-Term Postoperative Outcome in 4432 Patients Consecutively Treated at the Mayo Clinic During Eight Decades (1936-2015).

BACKGROUND: Contemporary guidelines for managing PTC advise an approach wherein primary tumor and regional metastases (RM) are completely resected at first surgery and radioiodine remnant ablation (RRA) is restricted to high-risk patients, policies our group has long endorsed. To assess our therapeutic efficacy, we studied 190 children and 4242 adults consecutively treated during 1936-2015. SUBJECTS AND METHODS: Mean follow-up durations for children and adults were 26.9 and 15.2 years, respectively. Bilateral lobar resection was performed in 86% of children and 88% of adults, followed by RRA in 30% of children and 29% of adults; neck nodes were excised in 86% of children and 66% of adults. Tumor recurrence (TR) and cause-specific mortality (CSM) details were taken from a computerized database. RESULTS: Children, when compared to adults, had larger primary tumors which more often were grossly invasive and incompletely resected. At presentation, children, as compared to adults, had more RM and distant metastases (DM). Thirty-year TR rates were no different in children than adults at any site. Thirty-year CSM rates were lower in children than adults (1.1 vs. 4.9%; p = 0.01). Comparing 1936-1975 (THEN) with 1976-2015 (NOW), 30-year CSM rates were similar in MACIS <6 children (p = 0.67) and adults (p = 0.08). However, MACIS <6 children and adults in 1976-2015 had significantly higher recurrence at local and regional, but not at distant, sites. MACIS 6+ adults, NOW, compared to THEN, had lower 30-year CSM rates (30 vs. 47%; p < 0.001), unassociated with decreased TR at any site. CONCLUSIONS: Children, despite presenting with more extensive PTC when compared to adults, have postoperative recurrences at similar frequency, typically coexist with DM and die of PTC less often. Since 1976, both children and adults with MACIS <6 PTC have a <1% chance at 30 years of CSM; adults with higher MACIS scores (6 or more) have a 30-year CSM rate of 30%.

OPTIMIZING LENVATINIB THERAPY IN PATIENTS WITH METASTATIC RADIOACTIVE IODINE-RESISTANT DIFFERENTIATED THYROID CANCERS.

OBJECTIVE: Lenvatinib is approved for use in advanced radioactive iodine-resistant differentiated thyroid cancers (RAIR-DTCs). Its efficacy is indisputable, but toxicities are great, creating daunting challenges for patients and providers. Few data regarding early adverse events and impact on quality of life (QOL) exist; we sought to clarify these issues by analyzing our initial postapproval lenvatinib experience. METHODS: Standardized patient education was implemented, providing detailed instructions and expert provider contacts to facilitate timely reporting of toxicities and guide responsive actions. Early adverse events, QOL outcomes, and response data from 25 consecutively treated DTC patients (02/2015 and 05/2016) were retrospectively analyzed. RESULTS: The median age was 55 years (range 27-81); 52% were female. Fourteen (56%) were on antihypertensive medication(s) at baseline. Most patients (21/25, 84%) developed adverse events during the first month of therapy. Hypertension arose in 16/25 (64%), requiring antihypertensive dose adjustment/addition in 6 (24%)/12 (48%) patients, respectively, during the first month of therapy. Dose reduction was required in 11 (44%) due to multiple adverse events; the median time to first dose reduction was 33 days (range 11-84); 8 (32%) required multiple dose reductions. Therapy interruption >3 weeks occurred in 4 (16%). The median change in patient-reported fatigue score was +2 (worsening, range -2 to +10, P<.007; 0-10 scales), but the median QOL change was 0 (range +4 to -9, P = .57). The mean duration of lenvatinib therapy was 6.5 months (range 1-12); median overall and progression-free survival have not yet been reached. Lenvatinib was discontinued in 7 (28%) patients; among 20 patients with available RECIST (Response Evaluation Criteria In Solid Tumors) measurements, 10 (50%) achieved partial response. CONCLUSION: Lenvatinib has promising efficacy in RAIR-DTC, but toxicities require frequent early interventions. QOL can be maintained on lenvatinib therapy. ABBREVIATIONS: DTC = differentiated thyroid cancer; LASA = linear analog self-assessment; PR = partial response; QOL = quality of life; RAI = radioactive iodine; RAIR = RAI-resistant; RECIST = Response Evaluation Criteria In Solid Tumors; Tg = thyroglobulin; VEGFR = vascular endothelial growth factor receptor.

Adrenal Hemorrhage: A Comprehensive Analysis of a Heterogeneous Entity-Etiology, Presentation, Management, and Outcomes.

OBJECTIVE: To investigate the etiology, presentation, management, and outcomes of patients with adrenal hemorrhage (AH). PATIENTS AND METHODS: Longitudinal study of consecutive adult patients with radiologically confirmed AH (January 1, 2017, through December 31, 2021). RESULTS: Of the 363 patients with AH (median age, 62 years [interquartile range (IQR, 52-70 years]; 128 women [35%]), 338 (93%) had unilateral AH and 25 (7%) had bilateral AH. It was discovered incidentally in 152 patients (42%) and during the evaluation of trauma in 103 (28%), abdominal/back pain in 90 (25%), critical illness in 13 (4%), and symptoms of adrenal insufficiency in 5 (1%). Etiologies included postoperative complications in 150 patients (41%), trauma in 107 (30%), coagulopathy in 22 (6%), anticoagulant/antiplatelet therapy in 39 (11%), adrenal neoplasm in 22 (6%), and sepsis in 11, (3%). Overall, 165 patients (46%) were hospitalized, and no deaths occurred due to AH. Median (IQR) baseline AH size was 34 mm (24-40 mm) on the right and 29 mm (22-37 mm) on the left. Among 246 patients with follow-up imaging, AH resolution was complete in 155 (63%) and incomplete in 74 (30%) at a median of 15 months (IQR, 6-31 months). Patients with bilateral AH were more likely to have underlying coagulopathy (44% vs 3%) and to develop primary adrenal insufficiency (72% vs 0%) than those with unilateral AH (P<.001). CONCLUSION: Often, AH presents as an incidental unilateral lesion with normal adrenal function, commonly attributed to postoperative complications or trauma. In contrast, bilateral AH is rare and typically linked to underlying coagulopathy, with primary adrenal insufficiency developing in most patients.

Clinical and imaging presentations are associated with function in incidental adrenocortical adenomas: a retrospective cohort study.

OBJECTIVE: The aim of this study is to assess whether clinical and imaging characteristics are associated with the hormonal subtype, growth, and adrenalectomy for incidental adrenal cortical adenomas (ACAs). DESIGN: This is a single-center cohort study. METHODS: Consecutive adult patients with incidental ACA were diagnosed between 2000 and 2016. RESULTS: Of the 1516 patients with incidental ACA (median age 59 years, 62% women), 699 (46%) had nonfunctioning adenomas (NFAs), 482 (31%) had mild autonomous cortisol secretion (MACS), 62 (4%) had primary aldosteronism (PA), 39 (3%) had Cushing syndrome, 18 (1%) had PA and MACS, and 226 (15%) had incomplete work-up. Age, sex, tumor size, and tumor laterality, but not unenhanced computed tomography Hounsfield units (HU), were associated with hormonal subtypes. In a multivariable analysis, ≥1 cm growth was associated with younger age (odds ratio [OR] = 0.8 per 5-year increase, P = .0047) and longer imaging follow-up (OR = 1.2 per year, P < .0001). Adrenalectomy was performed in 355 (23%) patients, including 38% of MACS and 15% of NFA. Adrenalectomy for NFA and MACS was more common in younger patients (OR = 0.79 per 5-year increase, P = .002), larger initial tumor size (OR = 2.3 per 1 cm increase, P < .0001), ≥1 cm growth (OR = 15.3, P < .0001), and higher postdexamethasone cortisol (OR = 6.6 for >5 vs <1.8 µg/dL, P = .002). CONCLUSIONS: Age, sex, tumor size, and laterality were associated with ACA hormonal subtype and can guide diagnosis and management. Tumor growth was more common with younger age and longer follow-up. Unenhanced HU did not predict hormonal subtype or growth. Adrenalectomy for MACS and NFA was mainly performed in younger patients with larger tumor size, growth, and elevated postdexamethasone cortisol.

Severe thyrotoxicosis as initial presentation of gastric choriocarcinoma: a case report.

BACKGROUND: Extragonadal choriocarcinoma is rare and can be associated with hyperthyroidism when producing very high levels of human chorionic gonadotropin. CASE PRESENTATION: A 62-year-old Hispanic female presented with a 3-week history of shortness of breath, palpitations, extreme weakness, new-onset hot flashes, and right flank pain. Her physical examination was remarkable for tachycardia, hepatomegaly, hyperreflexia, and tremor; goiter was absent. Laboratory studies revealed increased lactate dehydrogenase, alkaline phosphatase, suppressed thyroid stimulating hormone, very elevated T4, and absent thyroid stimulating immunoglobulin. 18F-fluorodeoxyglucose positron emission tomography-computed tomography exhibited hepatomegaly with multiple large fluorodeoxyglucose-avid liver masses and a focus of fluorodeoxyglucose avidity in the stomach with no structural correlate. A thyroid scan (99mTcO 4 - ) showed diffusely increased tracer uptake. She was started on propranolol and methimazole. Upon stabilization of severe thyrotoxicosis, upper endoscopy was performed, showing a ~ 5 cm bleeding lesion in the greater stomach curvature body; biopsy was consistent with choriocarcinoma; beta-human chorionic gonadotropin hormone was 2,408,171 mIU/mL. The patient received methotrexate followed by etoposide and cisplatin. Methimazole was titrated down, and upon liver failure the medication was stopped. The thyrotoxicosis was effectively controlled with antithyroid drug and concurrent chemotherapy. At ~ 1.5 months after initial diagnosis, the patient died due to bleeding/acute liver failure with coagulation defects followed by multiple organ failure. CONCLUSIONS: Severe thyrotoxicosis can represent an unusual initial presentation of metastatic choriocarcinoma in the setting of extreme elevation of beta-human chorionic gonadotropin. Primary gastric choriocarcinoma is an aggressive malignancy with very poor outcomes. The co-occurrence of severe thyrotoxicosis with advanced primary gastric choriocarcinoma and imminent liver failure complicates management options.

Inability of Radioiodine Remnant Ablation to Improve Postoperative Outcome in Adult Patients with Low-Risk Papillary Thyroid Carcinoma.

OBJECTIVE: To determine whether radioiodine remnant ablation (RRA) reduces cause-specific mortality (CSM) or tumor recurrence (TR) rate after bilateral lobar resection (BLR). PATIENTS AND METHODS: There were 2952 low-risk adult papillary thyroid cancer (LRAPTC) patients (with MACIS scores <6) who underwent potentially curative BLR during 1955-2014. During 1955-1974, 1975-1994, and 1995-2014, RRA was administered in 3%, 49%, and 28%. Statistical analyses were performed using SAS software. RESULTS: During 1955-1974, the 20-year CSM and TR rates after BLR alone were 1.0% and 6.8%; rates after BLR+RRA were 0% (P=.63) and 5.9% (P=.82). During 1975-1994, post-BLR 20-year rates for CSM and TR were 0.3% and 7.5%; after BLR+RRA, rates were higher at 0.9% (P=.31) and 12.8% (P=.01). When TR rates were examined separately for 448 node-negative and 317 node-positive patients, differences were nonsignificant. In 1995-2014, post-BLR 20-year CSM and TR rates were 0% and 9.2%; rates after BLR+RRA were higher at 1.4% (P=.19) and 21.0% (P<.001). In 890 pN0 cases, 15-year locoregional recurrence rates were 3.4% after BLR and 3.7% after BLR+RRA (P=.99). In 740 pN1 patients, 15-year locoregional recurrence rates were 10% higher after BLR+RRA compared with BLR alone (P=.01). However, this difference became nonsignificant when stratified by numbers of metastatic nodes. CONCLUSION: RRA administered to LRAPTC patients during 1955-2014 did not reduce either the CSM or TR rate. We would therefore not recommend RRA in LRAPTC patients undergoing BLR with curative intent.

Inappropriate use of thyroid ultrasound: a systematic review and meta-analysis.

PURPOSE: Nearly half the cases of thyroid cancer, a malignancy rapidly rising in incidence within the United States, are attributable to small and asymptomatic papillary thyroid cancers that will not increase mortality. A primary driver of thyroid cancer overdiagnosis is ultrasound use. It is therefore valuable to understand how inappropriate use of thyroid ultrasound is defined, analyze the current evidence for its frequency, and identify interventions to lessen misuse. METHODS: Ovid MEDLINE(R), Ovid EMBASE, and Scopus databases were searched from inception to June 2020 for studies assessing inappropriate use of thyroid ultrasound. Reviewers, working independently and in duplicate, evaluated studies for inclusion, extracted data, and graded risk of bias. We used a random-effects model with a generalized linear mixed approach to calculate the mean overall proportion estimates of inappropriate use. RESULTS: Seven studies (total n = 1573) met the inclusion criteria with moderate to high risk of bias. Inappropriate thyroid ultrasound use was described variably, using published practice guidelines, third-party expert reviewers, or author interpretations of the literature. The overall frequency of inappropriate thyroid ultrasound use was 46% (95% CI 15-82%; n = 388) and 34% (95% CI 16-57%; n = 190) among studies using guideline based definitions. The pooled frequency of iUS due to thyroid dysfunction (either hypothyroidism or thyrotoxicosis) was 17% (95% CI 7-37%; n = 191) and the frequency of iUS due to nonspecific symptoms without a palpable mass was 11% (95% CI 5-22%; n = 124). No study examined interventions to address inappropriate use. CONCLUSIONS: Low quality evidence suggests that inappropriate use of thyroid ultrasound is common. Interventional studies aiming to decrease the inappropriate use of thyroid ultrasound are urgently needed.
