RESUMO
INTRODUCTION: Guidelines recommending genetic counseling in primary hyperparathyroidism (PHPT) vary. To further delineate current recommendations, this study examined genetic counseling referral patterns and rates of mutations in surgical patients with PHPT. PATIENTS AND METHODS: A single-institution review was performed of adult patients who underwent parathyroidectomy for presumed sporadic PHPT. Genetic testing indications of hypercalcemia onset ≤ 40 years, multigland disease (MGD), family history (FHx) of PHPT, or other clinical indications suspicious for a PHPT-related endocrinopathy were examined by demographics and mutation detection rates. RESULTS: Genetic counseling was performed in 237 (37.9%) of 625 patients. Counseling was discussed but not performed in 121 (19.4%) patients. No evidence was noted of genetic referral discussion in the remaining 267 (42.7%). Of these groups, patients who received genetic counseling were youngest, p < 0.001 [median age 55.3 (IQR 43.2, 66.7) years]. The majority of patients with indications of age ≤ 40 years (65.7%), FHx (78.0%), and other clinical indications (70.7%) underwent genetic counseling, while most with MGD (57.0%) did not. Eight mutations were detected in 227 patients (3.5%). Mutations included: MEN1 (n = 2), CDC-73 (n = 4), and CASR (n = 2). Detection was most common in patients with FHx (4/71, 5.6%), then age ≤ 40 years (3/66, 4.5%), and other clinical indications (3/80, 3.8%). No mutations were identified in 48 patients tested solely for MGD. CONCLUSIONS: Most patients with onset of hypercalcemia age ≤ 40 years, positive FHx, or other clinical concerns underwent genetic counseling, while most with MGD did not. As no germline mutations were identified in patients with MGD alone, further investigation of MGD as a sole indication for genetic counseling may be warranted.

BACKGROUND: Secondary adrenal insufficiency (SAI) may occur in patients after unilateral adrenalectomy for adrenal-dependent hypercortisolism (HC) or primary aldosteronism (PA). This study aimed to assess whether postoperative day (POD) 1 basal cortisol was predictive of an abnormal cosyntropin stimulation test (CST) result and the need for glucocorticoid replacement (GR). METHODS: A retrospective review of consecutive patients who underwent unilateral adrenalectomy for HC, PA, or both between September 2014 and September 2022 was performed. On POD1, CST was performed for all the patients with HC, and before 2021 for all the patients with PA. The patients with an abnormal CST result were deemed at risk of SAI and discharged with GR. Receiver operating characteristic (ROC) curves were generated to evaluate the sensitivity (SN) and specificity (SP) of basal cortisol thresholds to predict an abnormal CST result. RESULTS: The patients underwent unilateral adrenalectomy for overt hypercortisolism (OH; n = 42), mild autonomous cortisol excess (MACE; n = 70), mixed PA/HC (n = 22), or PA (n = 73). On POD1, CST was performed for 152 patients (93% OH, 96% MACE,73% PA/HC, 41% PA), and 80 patients (53%) had SAI (67% OH, 55% MACE, 44% PA/HC, 33% PA). The SN and SP of a basal cortisol level of 10 µg/dL or lower to predict an abnormal CST were respectively 92% and 77% for OH, 94% and 73% for MACE, 100% and 85% for PA, and 100% and 67% for PA/HC. The optimal basal cortisol level for predicting an abnormal CST for patients with PA or PA/HC was 5 µg/dL or lower (SN/SP, 100%). CONCLUSIONS: After unilateral adrenalectomy for HC, PA, or mixed PA/HC, POD1 CST improved identification of patients at risk for SAI compared with basal cortisol levels alone. The authors recommend that POD1 CST be performed to determine the risk for SAI and the need for postoperative GR after unilateral adrenalectomy for patients with HC.
RESUMO
INTRODUCTION: Calcium metabolism dysregulation in the setting of primary hyperparathyroidism (PHPT) mediated chondrocalcinosis is implicated in joint pain, a key element in the decision regarding arthroplasty for osteoarthritis. The relationship between hypercalcemia and joint pain, before and after arthroplasty, is unknown. This study investigates the association between preoperative hypercalcemia and postoperative outcomes following total knee (TKA) and total hip arthroplasty (THA). METHODS: A retrospective chart review was conducted on patients who underwent initial elective THA or TKA. Patients with a preoperative serum calcium >10.2 mg/dL were matched (1:2-1:4) with nearest neighbor to patients with normal serum calcium. THA and TKA functional outcomes were measured at baseline and 1-y postoperatively using patient-reported Hip Disability and Osteoarthritis Outcome Scores and Knee Injury and Osteoarthritis Outcome Scores surveys. Postoperative complications, readmissions, length of stay, and functional outcome scores were compared. RESULTS: Four hundred ninety-five patients (106 hypercalcemic cases, 389 matched controls) were included. Of these, 223 patients underwent THA (46 cases; 177 controls) and 272 patients underwent TKA (61 cases; 211 controls). There were no differences in Hip Disability and Osteoarthritis Outcome Scores and Knee Injury and Osteoarthritis Outcome Scores scores, postoperative complications, readmissions, or length of stay between cases and controls. Only 19/106 (18%) hypercalcemic patients had a parathyroid hormone (PTH); of these, 9 (47%) had possible PHPT (PTH > 40). CONCLUSIONS: Patients with hypercalcemia undergoing arthroplasty have similar functional and postoperative outcomes as normocalcemic patients. As PTH was obtained in <20% of hypercalcemic cases and 50% had possible PHPT, we recommend that hypercalcemic patients undergo PHPT workup. Additional investigation is needed to determine the effect of PHPT on arthroplasty outcomes.
RESUMO
OBJECTIVE: To determine how the severity of prior history (Hx) of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection influences postoperative outcomes after major elective inpatient surgery. BACKGROUND: Surgical guidelines instituted early in the coronavirus disease 2019 (COVID-19) pandemic recommended a delay in surgery of up to 8 weeks after an acute SARS-CoV-2 infection. This was based on the observation of elevated surgical risk after recovery from COVID-19 early in the pandemic. As the pandemic shifts to an endemic phase, it is unclear whether this association remains, especially for those recovering from asymptomatic or mildly symptomatic COVID-19. METHODS: Utilizing the National COVID Cohort Collaborative, we assessed postoperative outcomes for adults with and without a Hx of COVID-19 who underwent major elective inpatient surgery between January 2020 and February 2023. COVID-19 severity and time from infection to surgery were each used as independent variables in multivariable logistic regression models. RESULTS: This study included 387,030 patients, of whom 37,354 (9.7%) were diagnosed with preoperative COVID-19. Hx of COVID-19 was found to be an independent risk factor for adverse postoperative outcomes even after a 12-week delay for patients with moderate and severe SARS-CoV-2 infection. Patients with mild COVID-19 did not have an increased risk of adverse postoperative outcomes at any time point. Vaccination decreased the odds of respiratory failure. CONCLUSIONS: Impact of COVID-19 on postoperative outcomes is dependent on the severity of illness, with only moderate and severe disease leading to a higher risk of adverse outcomes. Existing perioperative policies should be updated to include consideration of COVID-19 disease severity and vaccination status.

BACKGROUND: Endocrine resistant metastatic disease develops in ~ 20-25% of hormone-receptor-positive (HR+) breast cancer (BC) patients despite endocrine therapy (ET) use. Upregulation of HER family receptor tyrosine kinases (RTKs) represent escape mechanisms in response to ET in some HR+ tumors. Short-term neoadjuvant ET (NET) offers the opportunity to identify early endocrine escape mechanisms initiated in individual tumors. METHODS: This was a single arm, interventional phase II clinical trial evaluating 4 weeks (± 1 week) of NET in patients with early-stage HR+/HER2-negative (HER2-) BC. The primary objective was to assess NET-induced changes in HER1-4 proteins by immunohistochemistry (IHC) score. Protein upregulation was defined as an increase of ≥ 1 in IHC score following NET. RESULTS: Thirty-seven patients with cT1-T3, cN0, HR+/HER2- BC were enrolled. In 35 patients with evaluable tumor HER protein after NET, HER2 was upregulated in 48.6% (17/35; p = 0.025), with HER2-positive status (IHC 3+ or FISH-amplified) detected in three patients at surgery, who were recommended adjuvant trastuzumab-based therapy. Downregulation of HER3 and/or HER4 protein was detected in 54.2% of tumors, whereas HER1 protein remained low and unchanged in all cases. While no significant volumetric reduction was detected radiographically after short-term NET, significant reduction in tumor proliferation rates were observed. No significant associations were identified between any clinicopathologic covariates and changes in HER1-4 protein expression on multivariable analysis. CONCLUSION: Short-term NET frequently and preferentially upregulates HER2 over other HER family RTKs in early-stage HR+/HER2- BC and may be a promising strategy to identify tumors that utilize HER2 as an early endocrine escape pathway. CLINICAL TRIAL REGISTRY: Trial registration number: NCT03219476.

BACKGROUND: Serum thyroglobulin (Tg) levels are used to monitor for differentiated thyroid cancer (DTC) recurrence and have been correlated with posttreatment disease burden. The clinical significance of Tg in the preoperative setting to predict the risk of DTC is unclear. Our aim is to examine the clinical utility of preoperative Tg levels in those undergoing thyroidectomies for DTC or benign disease. MATERIALS AND METHODS: From a prospectively collected database, we identified 385 patients who underwent thyroidectomy from 01/14 to 12/19 and had preoperative Tg levels available. Preoperative Tg levels were compared by preoperative indication for surgery, Bethesda category of biopsied nodules, presence of DTC on surgical pathology, and number of metastatic lymph nodes. RESULTS: There was no difference in mean preoperative Tg level when comparing indication for surgery (P = 0.2) or Bethesda classification (P = 0.4). Mean preoperative Tg levels were lower in patients with DTC (238 ± 77) compared to without DTC (532 ± 97) on final pathology (P = 0.02). Among 188 DTC patients who had lymph nodes removed, there was no significant correlation between the preoperative Tg level and number of positive lymph nodes on final pathology (P = 0.4). CONCLUSIONS: Preoperative serum Tg levels were lower in patients with DTC compared to those with benign disease on final pathology and did not correlate with extent of lymph node metastasis in patients with DTC. We found that serum Tg levels obtained in the preoperative setting do not predict DTC or lymph node metastasis and, therefore, do not inform the extent of surgery for differentiated thyroid cancer.

OBJECTIVE: In patients with primary aldosteronism, adrenal venous sampling (AVS) is performed to determine the presence of unilateral or bilateral adrenal disease. During AVS, verification of catheter positioning within the left adrenal vein (AV) and the right AV by comparison of AV and inferior vena cava (IVC) cortisol levels can be variable. The objective of this study was to determine the utility of AV epinephrine levels in assessing successful AV cannulation. METHODS: This was a single institution, retrospective review of patients who underwent AVS with cosyntropin stimulation for primary aldosteronism between 2009 and 2018. Successful cannulation of the AV was defined by an AV/IVC cortisol ratio selectivity index (SI) ≥3:1. Epinephrine thresholds to predict catheter placement in the AV were determined using logistic regression. The calculated epinephrine thresholds were compared with previously published thresholds. RESULTS: AVS was performed on 101 consecutive patients and, based on the SI, successful cannulation of the left AV and right AV occurred in 98 (97%) and 91(90%) patients, respectively. The calculated optimal epinephrine threshold to predict AV cannulation was 364 pg/mL (sensitivity, 92.1%; specificity, 94.6%) and the calculated optimal AV/IVC epinephrine ratio threshold was 27.4, (sensitivity, 92.1%; specificity, 91.3%). Among the 14 patients with failed AV cannulation, 3 patients would have been considered to have successful AVS using AV epinephrine levels >364 pg/mL and AV/IVC epinephrine ratio >27.4 thresholds. CONCLUSION: Obtaining 2 right AV samples routinely as well as AV and IVC epinephrine levels during AVS could prevent unnecessary repeat AVS in patients with failed AV cannulation based on cortisol-based SI <3:1.

PURPOSE: Small, abnormal parathyroid glands are usually associated with multigland hyperplasia in patients with primary hyperparathyroidism (pHPT). The purpose of this study was to determine the association between parathyroid adenoma size and biochemical cure rates in patients undergoing single gland parathyroidectomy. METHODS: The study included patients with sporadic pHPT who underwent initial parathyroidectomy and met intraoperative PTH criteria for cure after resection of a single adenoma (SGD). Patients were divided into quartiles (Q1 = smallest) based on gland weight and maximum dimension; cure rates were compared across groups. RESULTS: A single parathyroid adenoma was removed in 517 patients, with a median gland weight of 500 mg (range 50-11890). Median maximum gland dimension was 15 mm (range 5-55). With median follow-up of 28 months (range 6-81), the biochemical cure rate was 97.1%. There was no difference in cure rate by gland weight (Q1 94.6%, Q2 96.9%, Q3 98.4%, Q4 98.5%, p = 0.217) or maximum gland dimension (Q1 95.6%, Q2 97.6%, Q3 97.1%, Q4 98.2%, p = 0.641). When Q1 patients (by gland weight) were divided by quartile, there was no difference in cure rates (93.1% [50-140 mg]; 95.2% [150-190 mg]; 97.1% [200-230 mg]; 93.3% [240-280 mg]; p = 0.665). CONCLUSION: For patients with pHPT who underwent single gland parathyroidectomy, there was no difference in cure rates by gland weight or maximum dimension. These data suggest that the removal of parathyroid adenomas as small as 50 mg with an appropriate decline in ioPTH likely represent single gland disease and additional exploration may not be necessary.

BACKGROUND: Decision making regarding the initial treatment of women with breast cancer is complicated. In the current study, the authors examined the relationship between treatment choices and their children's ages among young women with early-stage breast cancer. METHODS: Using the MarketScan Commercial Claims and Encounters database, the authors identified women aged 20 to 50 years who underwent lumpectomy or mastectomy for early-stage breast cancer between 2008 and 2014. Predictors of compliance with radiotherapy after undergoing lumpectomy and of undergoing mastectomy were determined using multinomial logistic regression. The authors conducted sensitivity analyses to explore the impact of the number of young-aged children and a reduction in the sample size in 2014 due to the attrition of health plans contributing to MarketScan. RESULTS: A total of 21,052 women were included in the current analysis. Among women with at least 1 child aged <7 years, the adjusted rate of lumpectomy was 59.9%; approximately 22% of these women did not receive radiotherapy. Compared with women undergoing lumpectomy plus radiotherapy, women with at least 1 child aged <7 years or aged 7 to 12 years were 25% and 16%, respectively, more likely to undergo lumpectomy alone compared with women with no children aged <18 years (P = .002 and P = .012, respectively) and 64% and 37%, respectively, more likely to undergo mastectomy (P < .001). CONCLUSIONS: Among privately insured women with breast cancer, having young children was found to be strongly associated with the omission of postlumpectomy radiotherapy or undergoing mastectomy. Having >1 young-aged child further amplified these associations. The findings of the current study suggested that caring for young children may present unique challenges to young women with breast cancer.

PURPOSE: Advanced practice providers (APPs) have increasingly become members of the oncology care team. Little is known about the scope of care that APPs are performing nationally. We determined the prevalence and extent of APP practice and examined associations between APP care and scope of practice regulations, phase of cancer care, and patient characteristics. METHODS: We performed an observational study among women identified from Medicare claims as having had incident breast cancer in 2008 with claims through 2012. Outpatient APP care included at least one APP independently billing for cancer visits/services. APP scope of practice was classified as independent, reduced, or restricted. A logistic regression model with patient-level random effects was estimated to determine the probability of receiving APP care at any point during active treatment or surveillance. RESULTS: Among 42,550 women, 6583 (15%) received APP care, of whom 83% had APP care during the surveillance phase and 41% during the treatment phase. Among women who received APP care during a given year of surveillance, the overall proportion of APP-billed clinic visits increased with each additional year of surveillance (36% in Year 1 to 61% in Year 4). Logistic regression model results indicate that women were more likely to receive APP care if they were younger, black, healthier, had higher income status, or lived in a rural county or state with independent APP scope of practice. CONCLUSIONS: This study provides important clinical and policy-relevant findings regarding national practice patterns of APP oncology care. Among Medicare beneficiaries with incident breast cancer, 15% received outpatient oncology care that included APPs who were billing; most of this care was during the surveillance phase. Future studies are needed to define the degree of APP oncology practice and training that maximizes patient access and satisfaction while optimizing the efficiency and quality of cancer care.

BACKGROUND: Ex vivo aspiration of parathyroid glands for the measurement of intraoperative parathyroid hormone (IOPTH) levels is a rapid point-of-care method to confirm parathyroid tissue during parathyroidectomy and an alternative to frozen section (FS). This study sought to determine the awareness and utilization of this technique among endocrine surgeons. MATERIALS AND METHODS: A de-identified 12-question survey regarding techniques for intraoperative identification/confirmation of parathyroid tissue and the use of IOPTH monitoring was distributed to all 608 members of the American Association of Endocrine Surgeons. RESULTS: Among the 182 (30%) respondents, FS was the most common primary technique utilized by 115 (63%) respondents to confirm parathyroid tissue; only 12 (7%) utilized ex vivo aspiration, although 78 (42%) were familiar with the technique. Availability and familiarity were the principal reasons for use of the primary technique; the most common barrier was time. Serum IOPTH monitoring was routinely used by 124 (74%). Of respondents who utilized FS, serum IOPTH monitoring was routinely used by 75% (86/115), including 71% (45/63) who reported time as a barrier to FS. Of these 45, only 15 (33%) were familiar with ex vivo parathyroid aspiration. Only 48% of surgeons knew how PTH samples were charged. CONCLUSIONS: FS was the most common method of identification/confirmation of parathyroid tissue. Although most respondents routinely performed IOPTH monitoring, relatively few utilized ex vivo aspiration as a technique for parathyroid identification and less than 50% were familiar with this technique. Broader dissemination about novel techniques such as ex vivo aspiration and cost awareness are recommended.

BACKGROUND: Persistent/recurrent hyperparathyroidism occurs in 2%-5% of patients with sporadic primary hyperparathyroidism (PHPT). In this study, the incidence and time to recurrence in patients with single-gland disease (SGD), double adenomas (DAs), or four-gland hyperplasia (FGH) at initial parathyroidectomy were compared. METHODS: This retrospective review included adult patients with sporadic PHPT who underwent initial parathyroidectomy with intraoperative parathyroid hormone monitoring (IOPTH) from 1/2000 to 12/2016 with ≥6 mo follow-up. An abnormal parathyroid was defined by a gland weight of ≥50 mg. A concurrent serum calcium >10.2 mg/dL and parathyroid hormone >40 pg/mL was defined as persistent PHPT if present <6 mo and recurrent PHPT if present ≥6 mo postoperatively after initial normocalcemia. RESULTS: Of 1486 patients, 1203 (81%) had SGD, 159 (11%) DA, and 124 (8%) FGH. Among the 3 groups, there was no difference in the percent decrease from the baseline or time of excision to final postexcision IOPTH levels between groups (79% versus 80% versus 80%, respectively; P = 0.954) or in the proportion of patients with a final IOPTH ≥40 (22% versus 18% versus 14%; P = 0.059). Overall, 22 (1.5%) had persistent PHPT and 26 (1.7%) had recurrent PHPT. Persistent PHPT was more frequent with DAs (6; 3.8%) than other groups (SGD: 16, 1.3%; FGH: 0; P = 0.02). At median follow-up of 33 mo (IQR, 18-60), there was no difference in recurrence rate (1.6% versus 2.5% versus 2.4%; P = 0.57) or median time (mo) to recurrence (SGD: 59 [IQR, 21-86], DAs: 36 [IQR, 29-58], FGH: 23 [IQR, 17-40]; P = 0.46). CONCLUSIONS: Recurrent PHPT occurred in 1.7% of patients who underwent curative initial parathyroidectomy, with no difference in incidence or time to recurrence between groups based on the number of glands removed. Patients with DA more commonly had persistent PHPT, raising the possibility of unrecognized FGH.

BACKGROUND: Prior to thyroidectomy for hyperthyroidism, it is recommended that patients are managed with antithyroid drugs (ATDs) and rendered euthyroid to decrease the risk of thyroid storm. However, not all patients tolerate ATD and the risk of thyroid storm during thyroidectomy in these patients is unclear. Therefore, the aim of this study was to compare the management and outcomes of hyperthyroid patients that were on ATDs prior to surgery to those who were not. STUDY DESIGN: A prospectively maintained, single-institution database was queried for all hyperthyroid patients who were initially treated with ATDs and underwent thyroidectomy from January 1, 2012, to June 18, 2018. Patients were divided into two groups: (1) those on ATDs at surgery (ATD group) and (2) those who could not tolerate and stopped ATDs prior to surgery (no-ATD group). Demographic and clinical data were collected. Primary outcomes were readmissions/emergency department visits and postoperative complications within 30 days of thyroidectomy. RESULTS: Of the 248 patients, 231 were in the ATD group and 17 (7%) were in the no-ATD group. There were no mortalities or thyroid storm events in either group. There was no difference in Clavien-Dindo Grade 2 or 3 complications between the two groups. There were no ED visits or 30-day readmissions in the no-ATD group compared to 17 (7%) events in the ATD group (p = 1.0). CONCLUSION: While it is preferable to render patients euthyroid prior to thyroidectomy for hyperthyroidism, results of this study suggest that when patients cannot tolerate ATDs, it is possible to perform thyroidectomy without increased risk of thyroid storm or intra- and postoperative complications.

PURPOSE: Since 2012, about 80 specialty societies have released Choosing Wisely (CW) recommendations aimed at reducing the use of low-value, unproven, or ineffective medical services. The extent to which these recommendations have influenced the behavior of physicians and patients remains largely unknown. METHODS: Using MarketScan Commercial Claims and Medicare Supplemental and Coordination of Benefits databases, we identified annual cohorts of women with incident, early-stage breast cancer and estimated the prevalence of four initial treatment and six surveillance metrics deemed as low-value breast cancer care by CW. Multivariable logistic regressions were subsequently used to estimate temporal trends and regional variation in the use of these metrics, with a special focus on the year of CW's publication. RESULTS: There were 122,341 women identified as undergoing treatment for incident breast cancer between 2010 and 2014. Two of the four low-value initial treatment metrics and four of the six low-value surveillance metrics declined significantly over time. The temporal trend of declining use, however, preceded the release of CW's guidelines. Declines ranged from 11.0% for follow-up mammography to 40.6% for receipt of surgical biopsy without an attempted needle biopsy. There were marked regional differences in use of low-value breast cancer care for all metrics, much of which persisted after publication of CW. CONCLUSIONS: With two notable exceptions, use of low-value breast cancer care has declined steadily since 2010. The declines, however, were not accelerated by the publication of CW recommendations.

BACKGROUND: Age-specific reference intervals (RIs) have been developed for biochemistry analytes in children. However, the ability to interpret results from multiple laboratories for 1 individual is limited. This study reports a head-to-head comparison of reference values and age-specific RIs for 30 biochemistry analytes for children across 5 analyzer types. METHODS: Blood was collected from healthy newborns and children 30 days to <18 years of age. Serum aliquots from the same individual were analyzed on 5 analyzer types. Differences in the mean reference values of the analytes by the analyzer types were investigated using mixed-effect regression analysis and by comparing maximum variation between analyzers with analyte-specific allowable total error reported in the Westgard QC database. Quantile regression was used to estimate age-specific RIs using power variables in age selected by fractional polynomial regression for the mean, with modification by sex when appropriate. RESULTS: The variations of age-specific mean reference values between analyzer types were within allowable total error (Westgard QC) for most analytes, and common age-specific reference limits were reported as functions of age and/or sex. Analyzer-specific reference limits for all analytes on 5 analyzer types are also reported as functions of age and/or sex. CONCLUSIONS: This study provides quantitative and qualitative measures of the extent to which results for individual children can or cannot be compared across analyzer types, and the feasibility of RI harmonization. The reported equations enable incorporation of age-specific RIs into laboratory information systems for improving evidence-based clinical decisions in children.

This is the second of a two-part review on adrenocortical carcinoma (ACC) management. While margin-negative resection provides the only potential cure for ACC, recurrence rates remain high. Furthermore, many patients present with locally advanced, unresectable tumors and/or diffuse metastases. As a result, selecting patients for adjuvant therapy and understanding systemic therapy options for advanced ACC is important. Herein, we detail the current literature supporting the use of adjuvant mitotane therapy, consideration of adjuvant radiation therapy, and utility of cytotoxic chemotherapy in patients with advanced disease. Ongoing investigation into molecular targeted agents, immunotherapy, and inhibitors of steroidogenesis for the treatment of ACC are also highlighted. Lastly, the importance of genetic counseling in patients with ACC is addressed as up to 10% of patients will have an identifiable hereditary syndrome.

This is the first of a two-part review on adrenocortical carcinoma (ACC), a rare and aggressive malignancy that often presents at an advanced stage. Most patients present with symptoms related to cortisol and/or androgen excess. Appropriate biochemical evaluation and imaging is important in assessing the extent of disease, operative planning, and oncologic surveillance for patients with ACC. For patients with locoregional disease, potential cure requires margin-negative resection, and accumulating evidence suggests that regional lymphadenectomy should be performed. Although laparoscopic adrenalectomy is reported by some to be adequate for localized ACC, open resection in the hands of an experienced adrenal surgeon is the gold standard for operative management of this disease. Cure is rare following disease relapse, however select patients with severe symptoms related to hormone excess or pain may benefit from resection of local or distant recurrence. For best oncologic outcomes, it is recommended that all patients with ACC be treated at centers with multidisciplinary expertise in management of this rare and aggressive malignancy.
