Abstract
Increasing pursuit of subspecialized training has quietly revolutionized physician training, but the potential impact on physician workforce estimates has not previously been recognized. The Physicians Specialty Data Reports of the Association of American Medical Colleges, derived from specialty designations in the American Medical Association (AMA) Physician Professional Data (PPD), are the reference source for US physician workforce estimates; by 2020, the report for pathologists was an undercount of 39% when compared with the PPD. Most of the difference was due to the omission of pathology subspecialty designations. The rest resulted from reliance on only the first of the AMA PPD's 2 specialty data fields. Placement of specialty designation in these 2 fields is sensitive to sequence of training and is thus affected by multiple or intercalated (between years of residency training) fellowships. Both these phenomena have become progressively more common and are not unique to pathology. Our findings demonstrate the need to update definitions and methodology underlying estimates of the US physician workforce for pathology and suggest a like need in other specialties affected by similar trends.

Abstract
Dosimetry after 177Lu-DOTATATE peptide receptor radionuclide therapy (PRRT) enables estimation of radiation doses absorbed by normal organs and target lesions. This process is time-consuming and requires multiple posttreatment studies on several subsequent days. In a previous study, we described a newly developed multiple-linear-regression model to predict absorbed doses (ADs) from a single-time-point (STP) posttreatment study acquired 168 h after the first infusion and 24 h after the following ones, with similar results to the standard multiple-time-point (MTP) protocol. The present study aimed to validate this model in a large patient cohort and to assess whether STP dosimetry affects patient management decisions compared with our MTP protocol. Methods: Quantitative 177Lu-DOTATATE SPECT/CT post-PRRT data from 159 consecutive patients (172 therapies, 477 therapy cycles) were retrospectively analyzed. ADs obtained from an STP model were compared with those obtained using an MTP model. We evaluated the impact of the STP model on the decision on whether PRRT should be stopped because of an expected kidney AD exceeding the safety threshold. We hypothesized that patient management based on the STP model does not differ from that based on the MTP model in at least 90% of the cases. Results: There was no difference in management decisions between the MTP and STP models in 170 of 172 therapies (98.8%). A Fisher χ2 test for combined probabilities produced a composite P value of 0.0003. Mean cumulative AD relative differences between the STP and MTP models were 0.8% ± 8.0%, -7.7% ± 4.8%, 0.0% ± 11.4%, -2.8% ± 6.3%, and -2.1% ± 18.4% for kidneys, bone marrow, liver, spleen, and tumors, respectively (Pearson r = 0.99 for all), for patients who underwent 4 therapy cycles. Similar results were obtained with fewer therapy cycles. Conclusion: Estimated radiation ADs and patient management decisions were similar with the STP and MTP models. The STP model can simplify the dosimetry process while also reducing scanner and staff time and improving patient comfort.

Abstract
We conducted a retrospective/prospective worldwide study on patients with neuroendocrine neoplasms (NENs) and a molecularly proven SARS-CoV-2 positivity. Preliminary results regarding 85 patients of the INTENSIVE study have been published in 2021. Now we are reporting the 2-year analysis.Here, we are reporting data from consecutive patients enrolled between 1 June 2020, and 31 May 2022. Among the 118 contacted centers, 25 were active to enroll and 19 actively recruiting at the time of data cut-off for a total of 280 patients enrolled. SARS-CoV-2 positivity occurred in 47.5% of patients in 2020, 35.1% in 2021, and 17.4% in 2022. The median age for COVID-19 diagnosis was 60 years. Well-differentiated tumors, non-functioning, metastatic stage, and gastroenteropancreatic (GEP) primary sites represented most of the NENs. COVID-19-related pneumonia occurred in 22.8% of the total, with 61.3% of them requiring hospitalization; 11 patients (3.9%) needed sub-intensive or intensive care unit therapies and 14 patients died (5%), in 11 cases (3.9%) directly related to COVID-19. Diabetes mellitus and age at COVID-19 diagnosis > 70 years were significantly associated with COVID-19 mortality, whereas thoracic primary site with COVID-19 morbidity. A significant decrease in both hospitalization and pneumonia occurred in 2022 vs 2020. In our largest series of NEN patients with COVID-19, the NEN population is similar to the general population of patients with NEN regardless of COVID-19. However, older age, non-GEP primary sites and diabetes mellitus should be carefully considered for increased COVID-19 morbidity and mortality. Relevant information could be derived by integrating our results with NENs patients included in other cancer patients with COVID-19 registries.

Abstract
CONTEXT.— There has long been debate about whether and when there may be a shortage of pathologists in the United States. One way to assess this is to survey the hiring experiences of pathology practices. A 2018 survey revealed a strong demand for pathologists, with expectations of continued strength. This study updates that prior analysis using data from a 2021 survey of pathology practice leaders. OBJECTIVE.— To assess the US pathologist job market and examine implications. DESIGN.— We analyzed data from the 2021 College of American Pathologists Practice Leader Survey. This survey queried practice leaders, including regarding the hiring of pathologists, the level of experience being sought, success in filling positions, and expectations for hiring in the next 3 years. RESULTS.— Among the 375 surveyed practice leaders (about one-third of all US pathology practices), 282 provided information about pathologist hiring in 2021. A total of 157 of these 282 practices (55.7%) sought to hire at least 1 pathologist in 2021, up from 116 of 256 practices (45.3%) in 2017; the mean number of pathologists hired per practice also increased. In 2021, a total of 175 of 385 positions (45.5%) were to fill new positions, compared with 95 of 249 positions (38.2%) in 2017. Most practice leaders were comfortable hiring pathologists with less than 2 years of posttraining experience. Practice leaders anticipated continued strong demand for hiring pathologists during the next 3 years. CONCLUSIONS.— Our analysis confirms that the demand in pathologist hiring is strong and much increased from 2017. We believe, in combination with other job market indicators, that demand may outstrip the supply of pathologists, which is limited by the number of trainees and has remained constant during the past 20 years.

Abstract
There has been little rigorous assessment of burnout among pathologists and pathology trainees. Given this relative dearth of relevant literature on pathologist burnout, this report aims to raise awareness of the issue among those working in and around this specialty. Our results are based on a survey given in conjunction with the American Board of Pathology's (ABPath) biennial Continuing Certification (CC) reporting of activities required of diplomates to maintain certification. The survey was voluntary, open to all diplomates participating in CC, and conducted over two consecutive years (2019 and 2020), with alternate years comprising different sets of diplomates. The data are based on 1256 respondents (820 from 2019 to 436 from 2020). The three highest aggregate reported rates of burnout (reported as experienced nearly all of the time, most of the time, or part of the time) occurred when respondents were in their first year of residency training (41.1%) and when they were in (47.6%) and beyond (46.6%) their first three years of practice. We considered this high-low-high, or U-shaped distribution in recollected burnout over time among pathologists a notable finding and investigated its distribution among respondents. Conversely at every point in their training and practice, from half to three-quarters of respondents reported never or infrequently experiencing burnout. This study represents the largest pathologist cohort survey to date about pathologists' burnout. Importantly, especially for those considering pathology as a career, these data are on the low end of the distribution of burnout among specialties for those in practice.

Abstract
BACKGROUND Cases of variations in anterior belly of the digastric muscle must be carefully identified to avoid misinterpretations and assist in the correct surgical or aesthetic procedure and help in the teaching of anatomy. The aim of this study was to describe the anatomical variations of anterior belly of digastric muscle in Brazilian cadavers. MATERIALS AND METHODS Thirty-one human heads were selected, from adult cadavers (18-80 years, 29 males and 2 females). The morphology of the anterior belly of the digastric muscle was observed, identifying the possible anatomical variations that were characterised and classified according to the amount of muscle bellies, fibre direction and place of origin and insertion. The morphometric measurements were performed using a digital calliper. To analyse the data obtained, photographic documentation, anatomical description and individual morphometric description of each muscle belly were performed. The incidence of anatomical variation was obtained in percentage (%). RESULTS The anatomical variation of the anterior belly of the digastric muscle was present in 6 cadavers (19.31%; 1 female and 5 male). All anatomical variations presented an accessory belly to the anterior belly. However, these accessory bellies were configured differently in the location, direction of muscle fibres and in their dimensions (length and width). CONCLUSIONS The gross anatomy of the anterior belly of the digastric muscle and their variations is important to assist in surgical procedures, pathological or diagnostic function. In addition, asymmetrical variations in the submental region must be carefully identified to avoid misinterpretations.

Abstract
Context Adrenocortical carcinoma (ACC) is a rare malignancy with poor prognosis for both locally advanced and metastatic disease. Standard treatment with combination etoposide–doxorubicin–cisplatin–mitotane (EDP-M) is highly toxic and some patients benefit from mitotane monotherapy. However, identification of these patients remains challenging. Objective We present a summary of the Israeli national referral center’s 20 years of experience in treating advanced ACC, with the aim of identifying prognostic factors and assisting in treatment decision making. Methods We conducted a retrospective multivariate analysis of patients treated for metastatic or locally advanced ACC at Hadassah Medical Center between 2000 and 2020 to determine clinical, pathological, and treatment factors correlated with overall survival (OS). Results In our cohort of 37 patients, a combination of modified European Network for the study of Adrenal Tumors (mENSAT) staging with either grade and R status, or age and symptoms was validated to stratify prognosis (P = .01 and P = .03, respectively). Patients who underwent R0 resection followed by radiotherapy or metastasectomy for oligometastatic disease had longer OS than patients with residual disease: median OS of 55 months vs 14 months, respectively, hazard ratio 3.1 (CI 1.4-6.7, P = .005). Patients treated with mitotane monotherapy had a significantly better prognosis, yet this result was attenuated in a multivariate analysis controlling for mENSAT and R status. Of patients treated with EDP-M, 41.4% experienced grade 3 or higher adverse events. Conclusion Patients with advanced ACC achieving R0 status have a better prognosis and might benefit from mitotane monotherapy.

Abstract
INTRODUCTION Telotristat ethyl is indicated for use in combination with somatostatin analogs (SSAs) to treat carcinoid syndrome (CS) diarrhea uncontrolled by SSAs alone in adults, but long-term safety and efficacy data beyond 48 weeks are needed. OBJECTIVES The aims of the study were to evaluate the long-term safety and tolerability of telotristat ethyl and its effect on quality of life (QOL) in patients with CS. METHODS In this phase 3, nonrandomized, multicenter, open-label, long-term extension study (TELEPATH), patients who participated in phase 2 or 3 trials of telotristat ethyl continued treatment at their present dose level (250 or 500 mg thrice daily) for 84 weeks. Safety and tolerability, the primary endpoint, were assessed by monitoring adverse events (AEs), serious AEs, AEs of special interest (AESIs; including liver-related AEs, depression, and gastrointestinal AEs), and deaths. The secondary objective was to evaluate changes in patients' QOL using validated cancer questionnaires and a subjective global assessment of CS symptoms. RESULTS In 124 patients exposed to telotristat ethyl for a mean of 102.6 ± 53.2 weeks, the type and frequency of AEs were consistent with those reported in previous trials. The occurrence of AESIs was not related to dosage or duration of therapy. Most AEs were mild to moderate in severity, and no deaths were related to telotristat ethyl. QOL scores remained stable, and the majority of patients reported adequate symptom relief throughout the study. CONCLUSIONS Safety results of TELEPATH support the long-term use of telotristat ethyl in patients with CS diarrhea. Telotristat ethyl was well-tolerated and associated with sustained improvement in QOL scores (NCT02026063).

Abstract
Background Following each cycle of peptide receptor radionuclide therapy (PRRT), absorbed doses by tumors and normal organs are typically calculated from three quantitative single-photon emission computed tomography (SPECT)/computed tomography (CT) studies acquired at t1 = 24 h, t2 = 96 h, t3 = 168 h after the first cycle of treatment and from a single study at t1 after the subsequent cycles. In the present study, we have assessed the feasibility of a single SPECT/CT study after each PRRT cycle using a trained multiple linear regression (MLR) model for absorbed dose calculation and have evaluated its impact on patient management. Quantitative [177Lu]-DOTA-TATE SPECT/CT data after PRRT of seventy-two consecutive metastatic neuroendocrine tumors patients were retrospectively evaluated. A set of 40 consecutive studies was used to train the MLR model. The two independent variables of the model included the time of imaging after administration of the treatment and the radiopharmaceutical activity concentration in a given organ/tumor. The dependent variable was the dose absorbed by the organ/tumor obtained with the standard protocol. For bone marrow dosimetry, the independent variables included the time of imaging, and the blood and remainder of the body activity concentration. The model was evaluated in 32 consecutive patients. Absorbed doses were assessed for kidneys, bone marrow, liver, spleen and tumor sites. Results There was no difference in management decisions, whether PRRT can be safely continued or not because unsafe absorbed dose to risk organs between the standard and the MLR model-based protocol using a single SPECT/CT study performed at t3 = 168 h after the first cycle and at t1 = 24 h after the subsequent cycles. Cumulative absorbed doses were obtained with mean relative differences of − 0.5% ± 5.4%, 1.6% ± 15.1%, − 6.2% ± 7.3%, − 5.5% ± 5.8% and 2.9% ± 12.7% for kidneys, bone marrow, liver, spleen and tumors, respectively (Pearson’s r correlation coefficient 0.99, 0.91, 0.99, 0.99 and 0.97, respectively). Conclusion Dosimetry calculations using a MLR model with a single SPECT/CT study are in good agreement with the standard protocol, while avoiding the use of dosimetry software and enabling improved patient comfort and reduced scanner and staff time.

Abstract
OBJECTIVE This in vivo study evaluated the influence of the sequence of all restorative steps during Class V preparation and restoration in human premolars on pulp temperature (PT). METHODS AND MATERIALS Intact premolars with orthodontic extraction indication of 13 volunteers received infiltrative anesthesia and isolation with rubber dam. An occlusal preparation was made with a high-speed diamond bur under air-water spray until the pulp was minimally exposed, then a thermocouple probe was inserted within the pulp. A deep, 2.0-mm depth Class V preparation was made using a high-speed diamond bur under air-water spray. Three restorative techniques were performed (n=7): Filtek Z250 placed in two increments (10-second exposure, shade:A2, 3M ESPE, St. Paul, MN, USA), Filtek Z350 XT (40-second exposure, shade:A3D, 3M ESPE) and Tetric N Ceram Bulk Fill (10-second exposure, shade:IVA, Ivoclar Vivadent, Schaan, Liechtenstein), both placed in a single layer. Bonding layer and resin composite were exposed to light from the same Polywave LCU (Bluephase 20i, Ivoclar Vivadent). The peak PT and the difference between peak PT and baseline (ΔT) values were subjected to two-way, repeated measures analysis of variance (ANOVA), followed by the Bonferroni post-hoc test (α=0.05). RESULTS Cavity preparation and etch & rinse procedures decreased the PT values (p<0.001). The 40-second exposure of Filtek Z350 caused the highest peak PT values (38.7±0.8°C) and the highest ΔT values (3.4±0.8°C), while Tetric N Ceram Bulk Fill showed the lowest values (-1.6±1.3°C; p=0.009). CONCLUSION None of the evaluated procedures resulted in a PT rise near to values that could offer any risk of thermal damage to the pulp.

Abstract
To assess the efficacy and safety of 177Lu-DOTATATE in patients with somatostatin receptor (SSR) positive lung neuroendocrine tumor (NET). Methods: This is a retrospective review of the outcome of patients with typical carcinoid (TC) and atypical carcinoid (AC), treated with 177Lu-DOTATATE at two ENETS Centres of Excellence. Morphological imaging (RECIST 1.1) and 68Ga-DOTATATE PET/CT responses were assessed at 3 months after completion of 177Lu-DOTATATE. Concordance between two response assessment methods was evaluated by Kappa statistics. Progression-free survival (PFS) and overall survival (OS) was estimated by Kaplan-Meier analysis and compared by Log-rank test. Treatment-related adverse events (AEs) were graded based on CTCAE version 5. Results: Of 48 patients (median age, 63 years, 13 female), 43 (90%) had AC and 5 (10%) TC. Almost all patients (47, 98%) were treated due to progression. Majority (40, 83%) received somatostatin analogs and 10 patients (20%) had prior everolimus, chemotherapy or both. All patients had high SSR expression (≥ modified Krenning score 3) on pre-treatment 68Ga-DOTATATE PET/CT. Patients received a median 4 (range 1-4) cycles of 177Lu-DOTATATE (33% with concurrent radiosensitizing chemotherapy) to a median cumulative activity of 27GBq (range 6-43GBq). At median follow-up of 42 months, the median PFS and OS were 23 months (95% CI 18-28 months) and 59 months (95% CI 50-not reached [NR]), respectively. Of 40 patients with RECIST-measurable disease and 39 patients with available 68Ga-DOTATATE PET/CT response categories were: partial response, 20% (95% CI 10-35%) and 44% (95% CI 30-59%); stable disease, 68% (95% CI 52-80%) and 44% (95% CI 30-59%) and progressive disease 12% (95% CI 5-27%) by both, respectively. There was a moderate concordance between response categories by RECIST and 68Ga-DOTATATE PET/CT, weighted Kappa of 0.51 (95% CI 0.21-0.68). Of patients with stable disease by RECIST, those with partial response on 68Ga-DOTATATE PET/CT had longer OS compared to those with no response, NR vs 52 months (95% CI 28-64), HR 0.2 (95% CI 0.1-0.6), p 0.001. Most grade 3/4 AEs were reversible and the most common was lymphopenia (14%) with no incidence of myelodysplasia/leukemia. Conclusion: In patients with advanced progressive lung NET and satisfactory SSR expression, 177Lu-DOTATATE is effective and safe with a high disease control rate and encouraging PFS and OS.

Abstract
Background: Sympathetic paragangliomas (PGL) are regarded as catecholamine-secreting, extra-adrenal counterparts of pheochromocytomas (PCC). Hormone producing head and neck PGL (HNPGL) are exceedingly rare, as most HNPGL are biochemically silent parasympathetic tumors. Here, we present a case of synchronous sympathetic cervical PGL and PCC. Clinical Case: A 47-year-old male was referred to the Neuroendocrine Tumor Unit clinic after a failed attempt at PGL removal at another center. The patient had a 10-year history of hypertension and a family history of his mother’s sudden death. Prior to referral, he presented with a palpable 6 cm right neck mass - an uneventful core-needle biopsy pathology revealed PGL. Subsequent workup showed profoundly elevated plasma metanephrine (MN) 3000 pg/ml [<65] and normetanephrine (NMN) 3500 pg/ml [<196]. Following a week of 2 mg/d doxazosin therapy, an attempt to operate on the patient for PGL was aborted after the skin incision over the mass due to an intraoperative hypertensive crisis. Upon arrival to our unit, reassessment disclosed a sustained stage 3 hypertension that required a four antihypertensive drug regimen with doxazosin dose titration up to 16 mg/d. MRI showed a 6 cm well-defined mass that displaced the common carotid artery and internal jugular vein (IJV) anteromedially, consistent with a PGL of sympathetic chain origin. MRA identified no tumor feeding vessels that could be suitable for embolization. Ga68 DOTATATE PET/CT showed a single focus of radiotracer uptake in the right neck PGL; however, the CT did image a 1.3 cm right adrenal mass with radiographic features suggestive of PCC. The patient underwent surgery for the PGL, using vigilant intraoperative hemodynamic and upper cranial nerve monitoring. An extreme hypertensive episode (systolic BP 340 mmHg) early on during the tumor’s dissection was resolved once the venous connection between the PGL and the IJV was divided. Pathology revealed a 6 cm PGL with free surgical margins. Postoperatively, hormone levels dropped significantly (MN 98 pg/ml [<65]; NMT 198 pg/ml [<196]). Subsequently, right adrenalectomy was performed, confirming the diagnosis of a 1.6 cm PCC. At the last follow-up, the patient’s hypertension was controlled on 5 mg/d amlodipine. Plasma MN and NMN levels were normal. Genetic analysis for PGL/PCC-associated genes revealed no germline mutation. Conclusion: This case highlights the importance of preoperative workup and perioperative management of large PGL. Head and neck PGL resection may be challenging depending on tumor size and location. Early division of the venous outflow from the PGL into the IJV plays a crucial role in intraoperative hemodynamic control. A multidisciplinary team at experienced centers must be involved in every aspect of the patient’s care to achieve optimal results.

Abstract
This article presents findings from a 4-year series of surveys of new-in-practice pathologists, and a survey of physician employers of new pathologists, assessing how pathology graduate medical education prepares its graduates for practice. Using the methodology described in our previous study, we develop evidence for the importance of residency training for various practice areas, comparing findings over different practice settings, sizes, and lengths of time in practice. The principal findings are (1) while new-in-practice pathologists and their employers report residency generally prepared them well for practice, some areas—billing and coding, laboratory management, molecular pathology, and pathology informatics—consistently were identified as being important in practice but inadequately prepared for in residency; (2) other areas—autopsy pathology, and subspecialized apheresis and blood donor center blood banking services—consistently were identified as relatively unimportant in practice and excessively prepared for in residency; (3) the notion of a single comprehensive model for categorical training in residency is challenged by the disparity between broad general practice in some settings and narrower subspecialty practice in others; and (4) the need for preparation in some areas evolves during practice, raising questions about the appropriate mode and circumstance for training in these areas. The implications of these findings range from rebalancing the emphasis among practice areas in residency, to reconsidering the structure of graduate medical education in pathology to meet present and evolving future practice needs.

Abstract
Background Image quality and quantitative accuracy of positron emission tomography (PET) depend on several factors such as uptake time, scanner characteristics and image reconstruction methods. Ordered subset expectation maximization (OSEM) is considered the gold standard for image reconstruction. Penalized-likelihood estimation (PL) algorithms have been recently developed for PET reconstruction to improve quantitation accuracy while maintaining or even improving image quality. In PL algorithms, a regularization parameter β controls the penalization of relative differences between neighboring pixels and determines image characteristics. In the present study, we aim to compare the performance of Q.Clear (PL algorithm, GE Healthcare) and OSEM (3 iterations, 8 subsets, 6-mm post-processing filter) for 68Ga-DOTATATE (68Ga-DOTA) PET studies, both visually and quantitatively. Thirty consecutive whole-body 68Ga-DOTA studies were included. The data were acquired in list mode and were reconstructed using 3D OSEM and Q.Clear with various values of β and various acquisition times per bed position (bp), thus generating images with reduced injected dose (1.5 min/bp: β = 300–1100; 1.0 min/bp: β = 600–1400 and 0.5 min/bp: β = 800–2200). An additional analysis adding β values up to 1500, 1700 and 3000 for 1.5, 1.0 and 0.5 min/bp, respectively, was performed for a random sample of 8 studies. Evaluation was performed using a phantom and clinical data. Two experienced nuclear medicine physicians blinded to the variables assessed the image quality visually. Results Clinical images reconstructed with Q.Clear, set at 1.5, 1.0 and 0.5 min/bp using β = 1100, 1300 and 3000, respectively, resulted in images with noise equivalence to 3D OSEM (1.5 min/bp) with a mean increase in SUVmax of 14%, 13% and 4%, an increase in SNR of 30%, 24% and 10%, and an increase in SBR of 13%, 13% and 2%. Visual assessment yielded similar results for β values of 1100–1400 and 1300–1600 for 1.5 and 1.0 min/bp, respectively, although for 0.5 min/bp there was no significant improvement compared to OSEM. Conclusion 68Ga-DOTA reconstructions with Q.Clear, 1.5 and 1.0 min/bp, resulted in increased tumor SUVmax and in improved SNR and SBR at a similar level of noise compared to 3D OSEM. Q.Clear with β = 1300–1600 enables one-third reduction of acquisition time or injected dose, with similar image quality compared to 3D OSEM.

Abstract
OBJECTIVE Von Hippel-Lindau (VHL) syndrome is a rare and complex disease. In 1996, we described a 3 generation VHL 2A kindred with 11 mutation carriers. We aim to share our experience regarding the long-term follow-up of this family and the management of all our other VHL patients focusing on frequently encountered neuroendocrine neoplasms: pheochromocytoma/paraganglioma and pancreatic neuroendocrine neoplasms (PNEN). METHODS All VHL patients in follow-up at our tertiary center from 1980 to 2019 were identified. Clinical, laboratory, imaging, and therapeutic characteristics were retrospectively analyzed. RESULTS We identified 32 VHL patients in 16 different families, 7/16 were classified as VHL 2 subtype. In the previously described family, the 4 initially asymptomatic carriers developed a neuroendocrine tumor; 7 new children were born, 3 of them being mutation carriers; 2 patients died, 1 due to metastatic PNEN-related liver failure. Pheochromocytoma was frequent (22/32), bilateral (13/22;59%), often diagnosed in early childhood when active screening was timely performed, associated with paraganglioma in 5/22, rarely malignant (1/22), and recurred after surgery in some cases after more than 20 years. PNEN occurred in 8/32 patients (25%), and was metastatic in 3 patients. Surgery and palliative therapy allowed relatively satisfactory outcomes. Severe disabling morbidities due to central-nervous system and ophthalmologic hemangiomas, and other rare tumors as chondrosarcoma in 2 patients and polycythemia in 1 patient were observed. CONCLUSION A multidisciplinary approach and long-term follow-up is mandatory in VHL patients to manage the multiple debilitating morbidities and delay mortality in these complex patients.

INTRODUCTION The lymph node ratio (LNR), which represents the proportion of metastatic lymph nodes resected, has been found to be a prognostic variable in several cancers, but data for Medullary thyroid carcinoma (MTC) are sparse. The aim of this study was to determine the value of the LNR in predicting outcome in patients with MTC. MATERIALS AND METHODS A retrospective multicenter study design of 107 patients with MTC who underwent total thyroidectomy with neck dissection between 1984 and 2016. The association of LNR with patient and tumor characteristics and prognostic factors was evaluated. RESULTS Study population consisted of 53.3% female, mean age at diagnosis was 50.3 ± 18.4 years; 16.8% had inherited MTC. LNR was positively correlated with tumor size (p = 0.018) and inversely correlated with age at diagnosis (p = 0.024). A higher LNR was associated with extrathyroidal extension (p < 0.001), multifocality (p = 0.001), bilateral tumor (p = 0.002), distant metastases (p < 0.001), and tumor recurrence (OR = 14.7, p < 0.001). LNR was also correlated to postoperative calcitonin levels (p < 0.001) and carcinoembryonic antigen (p = 0.011). LNR >0.1 was associated with shorter disease-specific survival in patients at risk: tumor larger than 20 mm at diagnosis (p = 0.013), sporadic MTC (p = 0.01), and age above 40 years at diagnosis (p = 0.004). Cox multivariate survival analysis revealed LNR as the only significant independent factor for disease free survival (p = 0.005). CONCLUSIONS This study showed that LNR correlates well with patient and tumor characteristics and prognostic variables. We suggest that LNR should be considered an important parameter for predicting outcome in MTC.

Abstract
PURPOSE The decreased life expectancy of MEN-1 patients is mainly related to pancreatic neuroendocrine tumors (pNETs). At best, limited data is available on the natural history of MEN-1-associated pNETs, as these tumors are rare and have a wide range of biologic behavior. Our study aims to explore the clinical course of patients with MEN-1-associated pNETs and the long-term outcomes. METHODS This longitudinal study was conducted on the MEN-1 cohort treated at our referral center over a 22-year period (1996-2018). Relevant clinical data were retrospectively analysed. RESULTS Among the 33 MEN-1 patients included in our study, pNETs were identified in 21 subjects with a penetrance of 48% by the age of 50. Non-functioning and functioning pNETs were diagnosed in sixteen (76%) and five (24%) patients, respectively. Two-thirds of the patients had multifocal tumors. The median number of pancreatic macroscopic lesions per individual was 4.0 ± 3.9 (range 1-8) with a mean size of 1.3 ± 2.1 cm (range 0.5-10). The metastatic rate according to the dominant pNET lesion reached 100%, 62% and 6% for tumors sized > 4 cm, 2.1-4 cm, and 1-2 cm, respectively. Over the study period, one or more therapeutic interventions for pNETs were required in 20 out of the 21 patients. pNET-related metastatic complication was the main cause of death within this MEN-1 cohort. The overall survival rate for the pNETs patients was 86% during a mean follow-up period of 8.0 ± 4.6 years. CONCLUSIONS In our MEN-1 cohort, non-functioning pNETs were the most frequent type of pancreaticoduodenal tumor, and the tumor size correlated with the risks of metastasis and death. Increased awareness, early diagnosis, and a multidisciplinary approach may improve the associated morbidity and mortality in these patients.

Abstract
BACKGROUND Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) is a rare lung disease associated with proliferation of neuroendocrine cells in the lung and multifocal neuroendocrine tumorlets/tumors. Although usually considered an indolent condition, DIPNECH causes chronic, progressive cough and dyspnea which can adversely impact quality of life. There is very limited information on the treatment of this condition. The objective of this study was to assess changes in symptoms and pulmonary function tests (PFTs) in response to somatostatin analog (SSA) treatment. METHODS Patients with clinical and/or pathologic diagnosis of DIPNECH and chronic respiratory symptoms were treated with SSAs at the H. Lee Moffitt Cancer Center and Research Institute, Hadassah-Hebrew University Medical Center, and Mayo Clinic Cancer Center. Their charts were reviewed to assess changes in symptoms and PFTs. RESULTS Forty-two patients were identified who had either chronic cough or dyspnea because of proven or suspected DIPNECH and who had received treatment with an SSA. Thirty-three patients experienced symptomatic improvement. Additionally, 14 of 15 patients in whom PFTs were checked were noted to have an improvement in FEV1 after treatment. CONCLUSIONS SSA treatment can improve chronic respiratory symptoms and PFTs in patients with DIPNECH.

Abstract
Background After each cycle of [177Lu]-DOTA-TATE peptide receptor radionuclide therapy (PRRT) dosimetry is performed to enable precise calculation of the radiation-absorbed dose to tumors and normal organs. Absorbed doses are routinely calculated from three quantitative single-photon emission computed tomography (SPECT) studies corrected by computed tomography (CT) acquired at t1 = 24 h, t2 = 96 h, and t3 = 168 h after the first cycle of treatment. After following cycles, a single SPECT/CT study is performed. The aim of the present study is to assess the feasibility of a “two time point” quantitative SPECT/CT protocol after the first PRRT cycle and its impact on patient management. Quantitative SPECT/CT data of 25 consecutive patients with metastatic neuroendocrine tumors after PRRT were retrospectively analyzed. Radiation-absorbed doses calculated using the standard protocol with three SPECT/CT studies acquired at (t1, t2, t3) were compared to those obtained from three different “two time point” protocols with SPECT/CT studies performed at (t1, t2), (t1, t3), or (t2, t3). Results The best agreement for the cumulative doses absorbed by the kidneys, bone marrow, liver, spleen, and tumors with the conventional protocol was obtained with the (t1, t3) protocol with mean relative differences of − 1.0% ± 2.4%, 0.4% ± 3.1%, − 0.9% ± 4.0%, − 0.8% ± 1.1%, and − 0.5% ± 2.0%, respectively, and correlation coefficients of r = 0.99 for all. In all patients, there was no difference in the management decision of whether or not to stop PRRT because of unsafe absorbed dose to risk organs using either the standard protocol or the (t1, t3) protocol. Conclusion These preliminary results demonstrate that dosimetry calculations using two quantitative SPECT/CT studies acquired at 24 and 168 h after the first PRRT cycle are feasible and are in good agreement with the standard imaging protocol with no change in patient management decisions, while enabling improved patient comfort and reduced scanner and staff time.

Abstract
CONTEXT.— Disagreement exists within the pathology community about the status of the job market for pathologists. Although many agree that jobs in pathology were harder to come by earlier this decade, recent evidence suggests improvement is occurring. OBJECTIVE.— To assess the state of the job market for pathologists. DESIGN.— We analyzed data from the 2018 College of American Pathologists Practice Leader Survey. This survey contains data from 253 practice leaders on practices' hiring (and retrenchments) in 2017, the skills and level of experience being sought, success in filling those positions, and expectations for hiring in the next 3 years. RESULTS.— Among the surveyed practice leaders, 115 (45.5%) sought to hire at least 1 pathologist in 2017, and together tried to fill 246 full-time equivalent positions that year, of which 93.5 full-time equivalents (38%) were newly created. This hiring was not limited to larger, academic-based practices, but also occurred among smaller practices and practices based in nonacademic hospitals, independent laboratories, and other settings. Although some practices retrenched (60 full-time equivalents in 2017), the net increase was a healthy 187 full-time equivalents. Practices most frequently sought pathologists who had at least 2 years of experience, but the level of experience identified with the "optimal" candidate varied by desired areas of subspecialty expertise. Practice leaders also reported expected growth in hiring, with the number of positions they hope to fill in the next 3 years exceeding those vacated by retirement. CONCLUSIONS.— Our findings support the proposition that the demand for pathologists is strong, at least at the current time.

Abstract
BACKGROUND An estimated 38% of US adults are obese. Obesity is associated with socioeconomic disparities and increased rates of comorbidities, and is a known risk factor for development of pancreatic cancer. As a fourth leading cause of death in the United States, pancreatic cancer is commonly treated with a pancreatico-duodenectomy (PD), or Whipple procedure. Data regarding the effects of obesity on post-operative complication rate primarily comes from specialized centers, however the results are mixed. Our aim is to elucidate the effects that obesity has on outcomes after PD for pancreatic head cancer using a national prospectively maintained clinical database. METHOD The 2010-2015 American College of Surgeons National Surgical Quality Improvement Project (ACS NSQIP) Participant Use Files (PUF) were used as the data source. We identified cases in which PD was performed (CPT code 48150) in the setting of a postoperative diagnosis of pancreatic cancer (ICD9 code 157.0). We excluded cases that had emergency admissions, BMI ≤18.5 kg/m2, intraoperative wound classification of III or IV, and disseminated cancer. Cases with missing BMI, preoperative albumin, operative time, LOS data were also excluded. Multiple imputation for missing sex, race, functional status, and ASA classification using chained equations was performed.16 Patients that had BMI ≥30 kg/m2 were considered obese, and patients with BMI <30 kg/m2 were used as control. RESULTS 3484 patients underwent pancreaticoduodenectomy for pancreatic cancer. 860 patients were identified as obese. Propensity score analysis was performed matching age, sex, race, functional status, presence of dyspnea, diabetes, hypertension, acute renal failure, dialysis dependence, ascites, steroid use, bleeding disorders, history of chronic obstructive pulmonary disease (COPD), congestive heart failure (CHF), weight loss, American Society of Anesthesiologists (ASA) classification, and preoperative albumin levels. After matching, obese patients had higher risk of 30-day postoperative complications compared to control, including organ space wound infections (OR 1.38, 95% CI 1.07-1.79, p = 0.0128), returning to the operating room (OR 1.39, 95% CI 1.01-1.91, p = 0.0461), failure to extubate for greater than 48 h (OR 1.60, 95% CI 1.09-2.34, p = 0.0153), death (OR 1.68, 95% CI 1.01-2.78, p = 0.0453), septic shock (OR 2.22, 95% CI 1.46-3.38, p = 0.0002), pulmonary embolism (OR 2.42, 95% CI 1.07-5.45, p = 0.0332), renal insufficiency (OR 2.67, 95% CI 1.33-5.38, p = 0.0058). Sensitivity analysis yielded similar results with the exception of risk for return to the operating room, death, and pulmonary embolism, P > .05. CONCLUSION In this large observational study using a national clinical database, obese patients undergoing PD for head of pancreas cancer had increased risk of postoperative complications and mortality in comparison to controls.

Abstract
OBJECTIVE Multiple clinical, pathological and biochemical variables, including the response to initial treatment, are associated with medullary thyroid carcinoma (MTC) prognosis. Studies that include separate analyses of familial and sporadic MTC patients followed for long period are scarce. This study evaluated the association between baseline clinico-pathologic variables and response to initial treatment and short- and long-term disease outcomes in sporadic and familial MTC. METHODS Patients treated for MTC at four tertiary medical centers were retrospectively analyzed. Clinical and pathological data were collected. The outcomes measured included disease persistence 1 year after diagnosis, disease persistence at last follow-up, disease-related mortality (DRM) and all-cause mortality. RESULTS The study enrolled 193 patients (mean age: 48.9 ± 18.7, 44.7% males), of whom 18.1% were familial cases. The mean follow-up period was 10.1 ± 9.4 years (8.5 ± 8.1 in sporadic and 16.9 ± 11.6 in familial MTC). Disease persistence 1-year after diagnosis and at last follow-up was detected in 56.1 and 60.4% patients, respectively. All-cause and DRM were 28.5 and 12.6%, respectively. Extra-thyroidal extension (ETE) and distant metastases (DM) were associated with disease persistence at last follow-up. ETE and DM were also significantly associated with DRM. Complete remission 1 year after diagnosis had high correlation with no evidence of disease at last follow-up (Cramer's V measure of association 0.884, P < 0.001) and with 100% disease-specific survival (Cramer's V measure of association 0.38, P < 0.001). CONCLUSIONS Apart from clinico-pathologic parameters, close correlation was found between 1-year status and long-term prognosis. These results underscore the importance of combining classical and dynamic factors for both sporadic and familial MTC prognostication and treatment decision making.

Abstract
CONTEXT Endoscopic ultrasound-guided radiofrequency ablation (EUS-RFA) is rapidly emerging as feasible therapy for patients with pancreatic neuroendocrine tumors (pNETs) in selected cases, as a result of its favorable safety profile. OBJECTIVE To assess the feasibility, safety, and efficacy of EUS-RFA in a cohort of patients with functional and nonfunctional pNETs (NF-pNETs). DESIGN Data on pNET patients treated with EUS-RFA between March 2017 and October 2018 at two tertiary centers was retrospectively analyzed. RESULTS The cohort included 18 adults (eight women, 10 men), aged 60.4 ± 14.4 years (mean ± SD), seven insulinoma patients, and 11 patients with NF-pNETs. Twenty-seven lesions with a mean diameter of 14.3 ± 7.3 mm (range 4.5 to 30) were treated. Technical success defined as typical postablative changes on a surveillance imaging was achieved in 26 out of 27 lesions. Clinical response with normalization of glucose levels was observed in all (seven of seven) insulinoma cases within 24 hours of treatment. Overall, there were no major complications 48 hours postprocedure. No clinically significant recurrences were observed during mean follow-up of 8.7 ± 4.6 months (range 2 to 21 months). CONCLUSIONS EUS-guided RFA of pNETs is a minimally invasive, safe, and technically feasible procedure for selected patients.

Abstract
PURPOSE To study the evolution and optimal management of metastatic bone disease (mBD) in patients with neuroendocrine neoplasms (NENs). METHODS Seventy-four patients were recruited from four NEN centers in this observational multicenter study. RESULTS Pancreas and small bowel were the most common primaries (30 and 27%, respectively). Almost all gastrointestinal (GI)-NENs were grades 1 and 2, whereas bronchopulmonary-thymic were atypical carcinoids. Thirty-two (43%) patients had synchronous metastatic bone disease (mBD) and three patients reported bone-specific symptoms; metachronous mBD developed at a median of 35 (range: 4-395) months. Thirty-six (86%) of patients with metachronous mBD had stage IV disease at diagnosis. Somatostatin receptor functional imaging and computed tomography were the modalities mostly used for mBD identification. Fifty-two patients received assessable bone-related therapy (bisphosphonates, denosumab, local radiotherapy, and radionuclide treatment). Improvement in mBD was seen in 5, stable disease in 22, and deterioration in 25 patients. The presence of synchronous mBD and the negative outcome of bone-related therapy negatively affected overall survival (OS). In the multivariate analysis, the stronger predictor of OS was the outcome of bone-related therapy (HR: 4.753; 95% CI: 1.589-14.213). Bisphosphonates therapy was the mostly used bone-specific treatment but its monthly administration did not affect OS. At last follow-up, 39 patients were alive with OS 50 (14-463) months. CONCLUSIONS Early investigation for mBD offers a prognostic marker of patients with NENs, since synchronous mBD has a negative impact on survival. The outcome of bone-related therapy affects OS but the monthly administration of bisphosphonates did not show a benefit over less intense schemes.

Abstract
BACKGROUND The aim of this study was to evaluate the predictive power of the absorbed dose to kidneys after the first course of treatment with [177Lu]-DOTA-TATE for neuroendocrine tumors (NETs) on the cumulative kidney absorbed dose after 3 or 4 cycles of treatment. Post-treatment scans (PTS) are acquired after each cycle of peptide receptor radionuclide therapy (PRRT) with [177Lu]-DOTA-TATE for personalized radiation dosimetry in order to ensure a cumulative absorbed dose to kidneys under a safety threshold of 25 Gy. One hundred eighty-seven patients who completed treatment with [177Lu]-DOTA-TATE and underwent PTS for dosimetry calculation were included in this retrospective study. The correlation between the cumulative absorbed dose to kidneys after the completion of treatment and the absorbed dose after the first cycle(s) was studied. Multilinear regression analysis was done to predict the cumulative absorbed dose to the kidneys of the subsequent cycles, and an algorithm for the follow up of kidney absorbed dose is proposed. RESULTS Patients whose absorbed dose to kidneys after the first cycle of treatment is below 5.6 Gy can receive four cycles of treatment with a cumulative dose less than 25 Gy (p < 0.1). For the other patients, the cumulative absorbed dose after 3 or 4 cycles of treatment can be predicted after the second cycle of treatment to allow for an early decision regarding the number of cycles that may be given. CONCLUSIONS The follow up of kidney absorbed dose after PRRT can be simplified with the algorithm presented in this study, reducing by one-third the number of post-treatment scans and reducing hospitalization time for more than half of the treatment cycles.

Abstract
CONTEXT.— As part of its value-based care initiative, the College of American Pathologists has pursued research to better understand the role pathologists can have in population health. OBJECTIVES.— To answer the following questions: (1) what is the impact of population health and population health management on pathologists; (2) what roles are pathologists playing in population health management; (3) is population health something that pathologists in both larger and smaller settings can engage in; (4) are pathologists in a position to analyze laboratory data for population health, and, if so, what are the key information sources those pathologists must access; and (5) what steps can a pathologist take to become involved in population health? DESIGN.— We conducted 10 semistructured interviews with pathologists and other medical laboratory leaders who have been active in population health. These interviews were supplemented with a review of the medical literature. RESULTS.— Pathologists have demonstrated that laboratory data can provide unique value-added contributions to improving the health of populations. These contributions are not limited to pathologists in large, integrated settings. However, pathologists need to be proactive to contribute to health systems' population health efforts and may need to both enhance their own skills and the quality of their data to maximize the value of their contributions. CONCLUSIONS.— Although not necessarily a definitive summary of the roles that pathologists are playing in population health, this article identifies some of the promising and innovative activities occurring among pathologists and laboratorians.

Abstract
BACKGROUND Multiple endocrine neoplasia (MEN) 2A is an autosomal dominant disorder that results from a mutation in the RET proto-oncogene on chromosome 10. Almost all of the affected patients develop medullary thyroid carcinoma (MTC). The American Thyroid Association recommends prophylactic thyroidectomy in MEN 2A pediatric patients, with the age of the recommended thyroidectomy varying according to the codon mutation present. OBJECTIVES This report questions the reliability of the currently placed guidelines and whether the age threshold for prophylactic thyroidectomy in patients with known codon 634 mutations should be lowered, in parallel with an earlier evaluation of calcitonin levels in the serum. METHODS We report the preoperative diagnosis as well as operative and postoperative course of a 3-year-old female patient with MEN 2A (codon 634 mutation) who underwent prophylactic thyroidectomy. The postoperative histopathologic findings are presented and discussed. RESULTS Despite the prophylactic nature of the operation, in parallel with a borderline calcitonin increase in the serum, bilateral MTC was discovered on pathology. CONCLUSION It is likely that the current guidelines should be revised to recommend calcitonin screening and prophylactic thyroidectomy at an earlier age for MEN 2A patients with known codon 634 mutations.

Abstract
Few medical specialties engage in ongoing, organized data collection to assess how graduate medical education in their disciplines align with practice. Pathology educators, the American Board of Pathology, and major pathology organizations undertook an evidence-based, empirical assessment of what all pathologists need to learn in categorical residency. Two challenges were known when we commenced and we encountered 2 others during the project; all were ultimately satisfactorily addressed. Initial challenges were (1) ensuring broad representation of the new-in-practice pathologist experience and (2) adjusting for the effect on this experience of subspecialty fellowship(s) occurring between residency and practice. Additional challenges were (3) needing to assess and quantify degree and extent of subspecialization in different practice settings and (4) measuring changing practice responsibilities with increasing time in practice. We instituted annual surveys of pathologists who are relatively new (<10 years) in practice and a survey of physician employers of new pathologists. The purpose of these surveys was to inform (1) the American Board of Pathology certification process, which needs to assess the most critical knowledge, judgment, and skills required by newly practicing pathologists, and (2) pathology graduate medical education training requirements, which need to be both efficient and effective in graduating competent practitioners. This article presents a survey methodology to evaluate alignment of graduate medical education training with the skills needed for new-in-practice physicians, illustrates an easily interpreted graphical format for assessing survey data, and provides high-level results showing consistency of findings between similar populations of respondents, and between new-in-practice physicians and physician-employers.

Abstract
Background Peptide receptor radionuclide therapy (PRRT) with [177Lu]-DOTA-TATE is an effective treatment of neuroendocrine tumors (NETs). After each cycle of treatment, patient dosimetry evaluates the radiation dose to the risk organs, kidneys, and bone marrow, the most radiosensitive tissues. Absorbed doses are calculated from the radioactivity in the blood and from single photon emission computed tomography (SPECT) images corrected by computed tomography (CT) acquired after each course of treatment. The aim of this work is to assess whether the dosimetry along all treatment cycles can be calculated using a single CT. We hypothesize that the absorbed doses to the risk organs calculated with a single CT will be accurate enough to correctly manage the patients, i.e., whether or not to continue PRRT. Twenty-four patients diagnosed with metastatic NETs undergoing PRRT with [177Lu]-DOTA-TATE were retrospectively included in this study. We compared radiation doses to the kidneys and bone marrow using two protocols. In the “classical” one, dosimetry is calculated based on a SPECT and a CT after each treatment cycle. In the new protocol, dosimetry is calculated based on a SPECT study after each cycle but with the first acquired CT for all cycles. Results The decision whether or not to stop PRRT because of unsafe absorbed dose to the risk organs would have been the same had the classical or the new protocol been used. The agreement between the cumulative doses to the kidneys and bone marrow obtained from the two protocols was excellent with Pearson’s correlation coefficients r = 0.95 and r = 0.99 (P < 0.0001) and mean relative differences of 5.30 ± 6.20% and 0.48 ± 4.88%, respectively. Conclusions Dosimetry calculations for a given patient can be done using a single CT registered to serial SPECTs. This new protocol reduces the need for a hybrid camera in the follow-up of patients receiving [177Lu]-DOTA-TATE.

The options for selective therapy in patients with unresectable multiple liver metastases are limited to TACE (transarterial chemoembolization), TAE (transarterial embolization), or SIRT (selective internal radiation therapy). AIM To explore the clinical outcome, survival and safety of these therapies in NETs patients. METHODS Retrospective case series of consecutive patients (mean age 56.6 years, 59% male) treated at two tertiary university medical centers from 2005 to 2015. RESULTS Fifty-seven patients with G1, G2, and low G3 NETs with liver metastases were investigated (pancreatic NET (pNET), 24; small bowel, 16; unknown origin (UKO), 9; rectal, 3; lung, 3; and gastric, 2). Fifty-three patients underwent TACE, three patients underwent TAE, and one patient underwent SIRT. Clinical improvement and tumor response were observed in 54/57 patients (95%), together with marked decreased in tumor markers. The median time to tumor progression following the first treatment was 14 ± 16 months. The median overall survival was 22 ± 18 months, more pronounced in the pNET, followed by small bowel and UKO subgroups. There was a trend for a better survival in patients with disease limited to the liver and in whom the primary tumor was resected. CONCLUSION Hepatic intra-arterial therapies are well tolerated in the majority of patients with NETs and liver metastases and associated with both clinical improvement and tumor stabilization for prolonged periods. These therapies should be always considered, irrespective of the presence of extrahepatic metastasis.

Abstract
Patients with neuroendocrine neoplasms (NENs) often require systemic treatment, which is frequently limited by the emergence of drug resistance. mTOR inhibitors (mTORi), such as RAD001 (everolimus), have been shown to inhibit neoplasm progression. mTORi stimulates autophagy, a degradation pathway that might promote the survival of neoplasm cells that are exposed to anti-cancer therapy. Chloroquine (CQ), a well-known anti-malarial and anti-rheumatic drug, suppresses autophagy. Based on our previous results, we hypothesized that CQ may enhance the anti-tumorigenic effects of mTORi by inhibiting autophagy and we aimed to examine the anti-tumorigenic effect of CQ, alone or in combination with RAD001. We established a NEN subcutaneous xenograft mouse model and evaluated the effect of the drugs on tumor growth, mTOR pathway, autophagy and apoptosis. CQ alone and in combination with RAD001 significantly decreased neoplasm volume. Histopathological analysis revealed that the combination of CQ and RAD001 markedly inhibited mTOR activity and neoplasm cell growth, along with accumulation of autophagosomes and increased apoptosis. In conclusion, CQ enhances the anti-tumorigenic effect of RAD001 in vivo by inhibiting autophagy. Clinical trials addressing the effects of CQ therapy on neoplasm progression in patients with NENs, mainly in those treated with mTORi, are warranted.

Abstract
BACKGROUND The widespread use of neck sonography in recent years has led to a dramatic increase in the detection of thyroid cancer, accompanied by changes in the clinicopathologic features of the disease. However, small papillary carcinomas account for the bulk of this increase, while little is known about temporal changes in medullary thyroid carcinoma (MTC). The aim of this study was to evaluate trends in the presentation, treatment, and outcome of MTC. METHODS Patients treated for MTC at four medical centers in Israel were divided into three groups by year of diagnosis: 19811995 (period A), 1996-2005 (period B), and 2006-2016 (period C). Clinicopathologic and survival data were collected retrospectively from the medical files and compared between the groups. RESULTS The cohort included 182 patients (54.9% female) with a mean age of 49.2 ± 18.7 years: 43 (23.6%) diagnosed in period A, 54 (29.7%) in period B, and 85 (46.7%) in period C. No significant differences were found between the groups in primary tumor size (25.7 ± 18.9 mm, 26.6 ± 18 mm, and 23.7 ± 17.6 mm, respectively), proportion of micro-MTC (30.8%, 20.0%, and 25.3%, respectively), or TNM staging. Age at diagnosis significantly increased over time (38.7 ± 17.2 years, 51.7 ± 18.4 years, and 53.7 ± 17.7 years, respectively; p < 0.001), and the rate of familial MTC significantly decreased (41.9%, 14.8%, and 8.2%, respectively; p = 0.002). Although the implementation of cervical lymph node dissection increased (62.1%, 78.4%, and 85%, respectively; p = 0.01), detection of metastatic lymph nodes decreased from 88.9% in period A to 65.0% in periods B and C (p = 0.06). There was no difference between the groups in disease-specific survival or disease-free state at one year from diagnosis (37.5%, 43.1%, and 50%, respectively) and last follow-up (27%, 41.2%, and 48%, respectively). Similar findings on MTC presentation and outcomes were obtained when only patients with non-familial MTC were analyzed. CONCLUSIONS Unlike differentiated thyroid cancer, most of the presenting features of MTC have not changed over time. The most significant temporal change is a decreased rate of familial MTC. Despite more extensive surgery and the use of new treatment modalities in recent years, significant improvement in disease-related outcomes were not found.

Abstract
Telotristat ethyl, a tryptophan hydroxylase inhibitor, was efficacious and well tolerated in the phase 3 TELESTAR study in patients with carcinoid syndrome (CS) experiencing ≥4 bowel movements per day (BMs/day) while on somatostatin analogs (SSAs). TELECAST, a phase 3 companion study, assessed the safety and efficacy of telotristat ethyl in patients with CS (diarrhea, flushing, abdominal pain, nausea or elevated urinary 5-hydroxyindoleacetic acid (u5-HIAA)) with <4 BMs/day on SSAs (or ≥1 symptom or ≥4 BMs/day if not on SSAs) during a 12-week double-blind treatment period followed by a 36-week open-label extension (OLE). The primary safety and efficacy endpoints were incidence of treatment-emergent adverse events (TEAEs) and percent change from baseline in 24-h u5-HIAA at week 12. Patients (N = 76) were randomly assigned (1:1:1) to receive placebo or telotristat ethyl 250 mg or 500 mg 3 times per day (tid); 67 continued receiving telotristat ethyl 500 mg tid during the OLE. Through week 12, TEAEs were generally mild to moderate in severity; 5 (placebo), 1 (telotristat ethyl 250 mg) and 3 (telotristat ethyl 500 mg) patients experienced serious events, and the rate of TEAEs in the OLE was comparable. At week 12, significant reductions in u5-HIAA from baseline were observed, with Hodges-Lehmann estimators of median treatment differences from placebo of -54.0% (95% confidence limits, -85.0%, -25.1%, P < 0.001) and -89.7% (95% confidence limits, -113.1%, -63.9%, P < 0.001) for telotristat ethyl 250 mg and 500 mg. These results support the safety and efficacy of telotristat ethyl when added to SSAs in patients with CS diarrhea (ClinicalTrials.gov identifier: Nbib2063659).

Abstract
CONTEXT Pheochromocytomas are hormone secreting tumors of the medulla of the adrenal glands found in 0.1-0.5% of patients with hypertension. The vast majority of pheochromocytomas secrete catecholamines, but they have been occasionally shown to also secrete interleukins, calcitonin, testosterone, and in rare cases adrenocorticotropic hormone. Pheochromocytoma crisis is a life threatening event in which high levels of catecholamines cause a systemic reaction leading to organ failure. CASE DESCRIPTION A 70-year-old man was admitted with acute myocardial ischemia following glucocorticoid administration as part of an endocrine workup for an adrenal mass. Cardiac catheterization disclosed patent coronary arteries and he was discharged. A year later he returned with similar angina-like chest pain. During hospitalization, he suffered additional events of chest pain, shortness of breath, and palpitations following administration of glucocorticoids as preparation for intravenous contrast administration. Throughout his admission, the patient demonstrated both signs of Cushing's syndrome and high catecholamine levels. Following stabilization of vital parameters and serum electrolytes, the adrenal mass was resected surgically and was found to harbor an adrenocorticotropic hormone secreting pheochromocytoma. This is the first documented case of adrenocorticotropic hormone secreting pheochromocytoma complicated by glucocorticoid induced pheochromocytoma crisis. CONCLUSION Care should be taken when administering high doses of glucocorticoids to patients with suspected pheochromocytoma, even in a patient with concomitant Cushing's syndrome.

Abstract
OPINION STATEMENT Neuroendocrine tumors (NETs) are rare neoplasms, with an estimated annual incidence of ~ 6.9/100,000. NETs arise throughout the body from cells of the diffuse endocrine system. More than half originate from endocrine cells of the gastrointestinal tract and the pancreas, thus being referred to as gastroenteropancreatic NETs (GEP-NETs). The only treatment that offers a cure is surgery; however, most patients are diagnosed with metastatic disease, and curative surgery is usually not an option. These patients can be offered long-term systemic treatment, for both symptomatic relief and tumor growth suppression. Evidence-based treatment options include somatostatin analogs, everolimus (a mTOR inhibitor), sunitinib (a tyrosine kinase inhibitor), and peptide receptor radionuclide therapy, alone or combined with cytoreductive procedures (surgery or liver-directed procedures). Other treatment options being investigated are immunotherapy and epigenetic assessment that may lead to more personalized interventions. We believe that each patient should be thoroughly evaluated and their case discussed by a multidisciplinary team that is up-to-date with all treatment modalities including ongoing clinical trials, before selecting the proper treatment option.

Abstract
PURPOSE Treatment options for unresectable paraganglioma (PGL)/pheochromocytoma (PCC), especially with uncontrolled secondary hypertension (HTN), are limited. Preliminary studies with peptide receptor radionuclide therapy (PRRT) suggest efficacy, but data on HTN control and survival are lacking. We assessed PRRT outcomes in such patients from two referral centers. METHODS Twenty consecutive patients (13 men; age range, 21 to 77 years) with high somatostatin receptor (SSTR) expression treated with 177Lu-DOTA-octreotate, nine with radiosensitizing chemotherapy, were retrospectively reviewed. Median cumulative activity was 22 GBq (median 4 cycles). Fourteen patients were treated for uncontrolled HTN and six for progressive or symptomatic metastatic disease or local recurrence. RESULTS Three months after PRRT, 8 of 14 patients treated for HTN required reduced medication doses, 5 had no change in anti-HTN doses, and 1 was lost to follow-up. Eighty-six percent had serum chromogranin-A reduction. Of the entire cohort, 36% had disease regression (29% partial and 7% minor response) on computed tomography, with stable findings in 50%. Three other patients had bony disease evaluable only on SSTR imaging (2 partial response and 1 stable). Median progression-free survival was 39 months; median overall survival was not reached (5 deaths; median follow-up, 28 months). Four patients had grade 3 lymphopenia; 2 had grade 3 thrombocytopenia. Renal impairment in 2 patients was attributed to underlying disease processes. CONCLUSIONS PRRT achieves worthwhile clinical and biochemical responses with low toxicity and encouraging survival in PGL/PCC. Because PRRT has logistic and radiation-safety advantages compared to 131I-MIBG therapy, further prospective evaluation is warranted.

Abstract
Background In the phase 3 RADIANT-2 study, everolimus plus octreotide long-acting repeatable (LAR) showed improvement of 5.1 months in median progression-free survival versus placebo plus octreotide LAR among patients with advanced neuroendocrine tumors associated with carcinoid syndrome. The progression-free survival P-value was marginally above the prespecified threshold for statistical significance. Here, we report final overall survival (OS) and key safety update from RADIANT-2. Patients and methods The RADIANT-2 trial compared everolimus (10 mg/day, orally; n = 216) versus placebo (n = 213), both in conjunction with octreotide LAR (30 mg, intramuscularly, every 28 days). Patients, unblinded at the time of progression or after end of double-blind core phase following primary analysis, were offered open-label everolimus with octreotide LAR (open-label phase). In the open-label phase, patients had similar safety and efficacy assessments as those in the core phase. For OS, hazard ratios (HRs) with 95% CIs using unadjusted Cox model and a Cox model adjusted for prespecified baseline covariates were calculated. Results A total of 170 patients received open-label everolimus (143 crossed over from the placebo arm; 27 in the everolimus arm continued to receive the same treatment after unblinding). The median OS (95% CI) after 271 events was 29.2 months (23.8-35.9) for the everolimus arm and 35.2 months (30.0-44.7) for the placebo arm (HR, 1.17; 95% CI, 0.92-1.49). HR adjusted for baseline covariates was 1.08 (95% CI, 0.84-1.38). The most frequent drug-related grade 3 or 4 AEs reported during the open-label phase were diarrhea (5.3%), fatigue (4.7%), and stomatitis (4.1%). Deaths related to pulmonary or cardiac failure were observed more frequently in the everolimus arm. Conclusion No significant difference in OS was observed for the everolimus plus octreotide LAR and placebo plus octreotide LAR arms of the RADIANT-2 study, even after adjusting for imbalances in the baseline covariates.

Abstract
We have recently documented that oral Linomide (quinoline-3-carboxamide) prevents autoimmune insulitis, islet destruction, and diabetes in NOD mice treated at an early stage (5 wk of age) of the disease. In this report, we show that treatment of female NOD mice with advanced disease (age 23-24 wk) by syngeneic islet transplantation and oral Linomide administration results in prevention of graft insulitis and diabetes in the Linomide group up to 40 wk (diabetes at 40 wk: isograft recipients with Linomide n = 0 of 6; isograft recipients alone n = 5 of 6; p < 0.0001). The extent of protection from glucose intolerance by the combination of transplantation with Linomide was superior to that of Linomide alone [blood glucose (mean ± SD) 60 min post-i.p. injection of 1 g/kg body weight glucose: Linomide plus isograft 6.7 ± 1 mmol/L; Linomide alone 18.7 ± 6.3 mmol/L; p < 0.0001]. Thus, Linomide should be considered a potential immunoregulatory modality in patients undergoing pancreatic islet or whole organ transplantation.

Abstract
BACKGROUND Liver metastases are relatively common in patients with metastatic medullary thyroid carcinoma (MTC), carrying a negative impact on disease prognosis. The options for selective therapy of liver metastases in MTC patients are limited to catheter-guided procedures such as trans-arterial chemoembolization (TACE). Data regarding the effectiveness and safety of this procedure in MTC are limited. AIM To explore the clinical outcome, survival and safety profile of TACE for liver metastases in a group of MTC patients. METHODS Retrospective case series of patients treated at a single tertiary University Medical Center from 2005 to 2015. RESULTS Seven consecutive patients (mean age 64.5 ± 10.9 years, 5 females) with histologically confirmed MTC with liver metastases were included. Metastatic involvement of the liver was less than 50% of the liver volume in all patients. The median size of the largest liver lesion was 40 ± 6.9 mm. The patients underwent in total 20 sessions of TACE. Clinical improvement as well as tumor response (PR) were observed in all patients. The median time to tumor progression was 38 months (range 8-126). Three patients were still alive at the end of the follow-up period (a median overall survival rate of 57 ± 44 months). CONCLUSION TACE in MTC patients with hepatic metastases is usually well tolerated and induces both clinical improvement and tumor response for prolonged periods of time in the majority of patients. This therapeutic option should always be considered, irrespective of the presence of extrahepatic metastasis.

Abstract
CONTEXT Hypoglycemia is a rare event in healthy adults, and the differential diagnosis includes many diseases, some of which are rare and easily missed. DESIGN, SETTING, DESCRIPTION A 20-year-old male military paramedic was referred to our emergency department for investigation of recurrent hypoglycemia episodes during the previous months. Factitious hypoglycemia was excluded, and organic hyperinsulinemic hypoglycemia was diagnosed by the findings from a prolonged fast. The findings from endoscopic ultrasonography and triple-phase computed tomography were normal. Before additional diagnostic tests or exploratory surgery were performed, a deeper interrogation of the patient and his family revealed events compatible with episodes of hypoglycemia since childhood. Moreover, a single event of hypoglycemia during childhood was documented in 1 brother, suggesting the possibility of an inborn, inherited metabolic disease. Because the patient was Ashkenazi Jewish, we suspected the presence of 1 of 2 common founder mutations in the ABCC8 gene, which codes for 1 subunit of the β-cell adenosine triphosphate-sensitive potassium channel, known to cause congenital hyperinsulinism of infancy. Direct sequencing revealed homozygosity for the ABCC8 gene mutation 3989-9 G>A. CONCLUSIONS The differential diagnosis of hyperinsulinemic hypoglycemia in a young healthy adult should include genetic disorders of glucose homeostasis. In the Ashkenazi population, rapid and inexpensive screening for 2 founder mutations can confirm the diagnosis, avoiding expensive, invasive, and potentially dangerous diagnostic procedures.

Abstract
A 55-year-old woman diagnosed with sporadic MTC underwent total thyroidectomy 20
years ago. After the first surgery, elevated calcitonin levels in parallel with local
disease persistence were noted and therefore she underwent repeated neck dissections.
During follow-up, multiple foci of metastatic disease were noted in the neck and
mediastinal lymph nodes, lungs and bones; however, the disease had an indolent course
for a number of years, in parallel with a calcitonin doubling time of more than two
years and without significant symptoms. During a routine follow-up visit 2 years ago,
findings suggestive of Cushing’s syndrome were observed on physical
examination. The biochemical evaluation demonstrated markedly elevated serum
calcitonin level, in parallel with lack of cortisol suppression after an overnight
1 mg dexamethasone suppression test, lack of cortisol and ACTH suppression
after high-dose IV dexamethasone 8 mg, elevated plasma ACTH up to
79 pg/mL (normal <46 pg/mL) and elevated 24-h urinary free cortisol
up to 501 µg/24 h (normal
9–90 µg/24 h). After a negative pituitary MRI, she
underwent IPSS, which was compatible with EAS. Whole-body CT demonstrated progressive
disease at most of the tumor sites. Treatment with vandetanib at a dosage of
200 mg/day was commenced. The patient showed a significant, rapid and
consistent clinical improvement already after two months of treatment, in parallel
with biochemical improvement, whereas a decrease in tumor size was demonstrated on
follow-up CT.

Abstract
BACKGROUND AND AIM OF THE STUDY The prosthetic valve of choice in patients with carcinoid valve disease (CVD) remains controversial due to the limited life expectancy of patients with advanced-stage neuroendocrine tumors (NETs) on the one hand, and concerns regarding structural valve deterioration (SVD) on the other hand. METHODS The records of 17 patients (11 females, seven males; mean age 65 ± 11 years; undergoing 18 operations) with primarily right heart failure due to CVD were reviewed. All patients received somatostatin analogs perioperatively. Hospital and follow up data (acquired via direct patient contact and echocardiography) collected included baseline characteristics, procedural details, and clinical outcomes. RESULTS The primary NET site was the ileum (n = 11), lungs (n = 2) and stomach, colon and appendix (n = 1 each). In one patient the primary tumor location could not be identified. Preoperative urinary levels of 5-hydroxyindole acetic acid (5-HIAA; 61 ± 36 mg/24 h) and serum levels of chromogranin A (2926 ± 4057 ng/ml) were 10- and 50-fold greater than normal, respectively. A total of 23 valves was implanted: five tricuspid valve replacements (TVR; four tissue and one mechanical), TVR and pulmonary valve replacements (PVR; three tissue and one mechanical), and TVR and mitral valve replacements (MVR; one tissue and two mechanical). The 30-day mortality was 11% (n = 2). No patient experienced a carcinoid crisis. The mean follow up was 24 ± 21 months (range: 4-85 months). Four patients (receiving seven valves) developed SVD at 12, 14, 15, and 20 months after surgery, and all of these patients died. The actuarial four-year survival and freedom from SVD were 23 ± 14% and 43 ± 15%, respectively. CONCLUSIONS The data acquired suggested that the main advantage of tissue valve prostheses, namely to avoid lifelong, intense anticoagulation, might be offset by accelerated SVD. The use of mechanical valves should be considered in CVD patients with a large primary tumor mass and persistent high urinary levels of 5-HIAA, and who are unresponsive to therapy.

Abstract
CONTEXT Pathologists are physicians who make diagnoses based on interpretation of tissue and cellular specimens (surgical/cytopathology, molecular/genomic pathology, autopsy), provide medical leadership and consultation for laboratory medicine, and are integral members of their institutions' interdisciplinary patient care teams. OBJECTIVE To develop a dynamic modeling tool to examine how individual factors and practice variables can forecast demand for pathologist services. DESIGN Build and test a computer-based software model populated with data from surveys and best estimates about current and new pathologist efforts. RESULTS Most pathologists' efforts focus on anatomic (52%), laboratory (14%), and other direct services (8%) for individual patients. Population-focused services (12%) (eg, laboratory medical direction) and other professional responsibilities (14%) (eg, teaching, research, and hospital committees) consume the rest of their time. Modeling scenarios were used to assess the need to increase or decrease efforts related globally to the Affordable Care Act, and specifically, to genomic medicine, laboratory consolidation, laboratory medical direction, and new areas where pathologists' expertise can add value. CONCLUSIONS Our modeling tool allows pathologists, educators, and policy experts to assess how various factors may affect demand for pathologists' services. These factors include an aging population, advances in biomedical technology, and changing roles in capitated, value-based, and team-based medical care systems. In the future, pathologists will likely have to assume new roles, develop new expertise, and become more efficient in practicing medicine to accommodate new value-based delivery models.

Abstract
BACKGROUND Everolimus (RAD001), an mTORC1 inhibitor, demonstrated promising, but limited, anticancer effects in neuroendocrine tumors (NETs). Torin1 (a global mTOR inhibitor) and NVP-BEZ235 (a PI3K/mTOR inhibitor) seem to be more effective than RAD001. Autophagy, a degradation pathway that may promote tumor growth, is regulated by mTOR; mTOR inhibition results in stimulation of autophagy. Chloroquine (CQ) inhibits autophagy. AIM To explore the effect of CQ alone or in combination with RAD001, Torin1 or NVP-BEZ235 on autophagy and on NET cell viability, proliferation and apoptosis. METHODS The NET cell line BON1 was treated with CQ with or without different mTOR inhibitors. siRNA against ATG5/7 was used to genetically inhibit autophagy. Cellular viability was examined by XTT, proliferation by Ki-67 staining and cell cycles by flow cytometry. Apoptosis was analyzed by Western blotting for cleaved caspase 3 and staining for annexin V; autophagy was evaluated by Western blotting and immunostaining for LC3. RESULTS RAD001, Torin1, NVP-BEZ235 and CQ all decreased BON1 cell viability. The effect of RAD001 was smaller than that of the other mTOR inhibitors or CQ. Torin1 and NVP-BEZ235 markedly inhibited cell proliferation, without inducing apoptosis. CQ similarly decreased cell proliferation, while robustly increasing apoptosis. Treatment with Torin1 or NVP-BEZ235 together with CQ was additive on viability, without increasing CQ-induced apoptosis. Inhibition of autophagy by ATG5/7 knockdown increased apoptosis in the presence or absence of mTOR inhibitors, mimicking the CQ effects. CONCLUSION CQ inhibits NET growth by inducing apoptosis and by inhibiting cell proliferation, probably via inhibition of autophagy. CQ may potentiate the antitumor effect of mTOR inhibitors.

Abstract
Approximately 35% of the pancreatic neuroendocrine tumors (pNETs) are functional, the most common of which is an insulinoma. Rarely can initially nonfunctioning tumor undergo biological transformation to a hormone-secreting tumor with subsequent changes in the clinical picture. We present here three unique patients with long-standing pNETs who developed life-threatening hyperinsulinemic hypoglycemia along with tumor progression. In two of the patients, everolimus (Afinitor) was administered in an attempt to control both tumor growth and hypoglycemia. In two cases everolimus therapy resulted in the abolishment of hypoglycemia and induced significant tumor regression; however these beneficial responses were transient. These cases highlight the exceptional ability of pNETs to change biological behavior in parallel with disease progression. Our experience concurs with recently published studies demonstrating the utility of everolimus for the control of both hypoglycemia and tumor progression.

Abstract
BACKGROUND Papillary thyroid carcinoma is the most common thyroid cancer (85%). Follicular thyroid carcinoma is the second most common type of thyroid cancer, accounting for up to 10% of all thyroid cancers. Medullary thyroid carcinoma accounts for only 5-8% of thyroid cancers. Concurrent medullary, follicular, and papillary carcinomas of the thyroid gland are extremely rare and reported scarcely. CASE REPORT A 72-year-old male presented with nonspecific neck pain. The workup revealed a nodular thyroid gland with a follicular lesion on fine-needle aspiration. Total thyroidectomy was performed and pathological examination identified a 25-mm follicular carcinoma, two papillary microcarcinomas, and two medullary microcarcinomas. The genetic workup was negative and no other family members were diagnosed with any endocrinopathy. Two months after surgery, the patient was diagnosed with Cushing's syndrome that was treated with laparoscopic left adrenalectomy. On 3-year follow-up, the patient is asymptomatic with no evidence of recurrent disease. CONCLUSION We present a rare case of a patient with follicular, papillary, and medullary thyroid carcinoma, and Cushing's syndrome. To date, no known genetic mutation or syndrome can account for this combination of neoplastic thyroid and adrenal pathologies, although future research may prove differently.

Abstract
Carcinoid heart disease (CHD) is a rare cardiac manifestation occurring in patients with advanced neuroendocrine tumours and the carcinoid syndrome, usually involving the right-sided heart valves and eventually leading to right heart failure. The pathophysiology of CHD is still obscure and believed to be multifactorial, as a variety of vasoactive substances secreted by the tumour appear to be involved. The management of patients with CHD is complex, as both the systemic malignant disease and the heart involvement have to be addressed. Timely diagnosis and early surgical treatment in appropriately selected patients are of outmost importance, as CHD is associated with increased morbidity and mortality. Valve replacement surgery alleviates right heart failure and may also contribute to improved survival. In the present study we have comprehensively reviewed the existing literature to date, mainly focusing on the pathophysiology of CHD. Other aspects of CHD (such as the clinical presentation, diagnostic tools and therapeutic approach) are addressed in brief.
