RESUMO
OBJECTIVE: Brachytherapy has been indicated as an alternative option for treating cystic craniopharyngiomas (CPs). The potential benefits of brachytherapy for CPs have not yet been clarified. The purpose of this work was to conduct a meta-analysis to analyze the long-term efficacy and adverse reactions profile of brachytherapy for CPs. MATERIALS AND METHODS: The relevant databases were searched to collect the clinical trials on brachytherapy in patients with CPs. Included studies were limited to publications in full manuscript form with at least 5-year median follow-up, and adequate reporting of treatment outcomes and adverse reactions data. Stata 12.0 was used for data analysis. RESULTS: According to the inclusion and exclusion criteria, a total of 6 clinical trials involving 266 patients with CPs were included in this meta-analysis. The minimum average follow-up was 5 years. The results of the meta-analysis showed that 1-year, 2-3 years and 5 years progression free survival rates (PFS) are 75% (95%CI: 66-84%), 62% (95%CI: 52-72%) and 57% (95%CI: 22-92%), respectively. At the last follow-up, less than 16% of patients with visual outcomes worser than baseline in all included studies. While, for endocrine outcomes, less than 32% of patients worser than baseline level. CONCLUSION: In general, based on the above results, brachytherapy should be considered as a good choice for the treatment of CP.

OBJECTIVE: Summarize and analyze the characteristics of patients with Multiple Endocrine Neoplasia type 1 (MEN-1) who were diagnosed with malignant tumors that do not belong to MEN-1 components. METHODS: Clinical data from patients with MEN-1 who visited Peking Union Medical College Hospital between April 2012 and April 2022 were collected. We compared the clinical characteristics of patients with malignant tumors outside of their MEN-1 components to those without additional tumors. MEN-1 gene testing was performed on most of these patients using Sanger sequencing, whole-exome sequencing, or MLPA. RESULTS: A total of 221 MEN-1 patients were diagnosed, of which 23 (10.40%) were found to have malignant tumors that did not belong to MEN-1 components, including papillary thyroid carcinoma (PTC) (4.52%), breast cancer (1.81%), urologic neoplasms (1.35%), primary hepatic carcinoma (PCC) (0.09%), meningeal sarcoma (0.05%), glioblastoma (0.05%), cervical cancer (0.05%), and lung carcinoma (0.05%). MEN-1 gene mutations were identified in 11 patients, including missense mutations, frameshift mutations, and splice mutations. The prevalence of each endocrine neoplasm, particularly gastroenteropancreatic neuroendocrine tumor, was higher in MEN-1 patients with other malignant tumors compared to MEN-1 patients without malignant tumors. CONCLUSION: Our retrospective study revealed a higher incidence of non-MEN-1 component malignant tumors in MEN-1 patients, especially breast cancer, PTC, and urologic neoplasms. These patients also exhibit more severe clinical phenotypes of MEN-1.

Objective To investigate the level of serum uric acid in patients with diabetes insipidus (DI),summarize the clinical characteristics of central diabetes insipidus (CDI) patients with hyperuricemia (HUA),and analyze the factors affecting the level of serum uric acid in the patients with CDI. Methods The clinical data of DI patients admitted to Peking Union Medical College Hospital from 2018 to 2021 were retrospectively analyzed.The patients were assigned into a child and adolescent group (≤ 18 years old) and an adult group (>18 years old) according to their ages.The demographic and biochemical data between two groups of patients with and without HUA were compared.Spearman correlation analysis and multiple linear regression analysis were performed to analyze the correlations between serum uric acid level and other factors. Results Among the 420 DI patients,411 patients had CDI (97.9%),including 189 patients with HUA (46.0%).Thirteen (6.9%) out of the 189 CDI patients with HUA presented the disappearance of thirst.The prevalence of HUA in children and adolescents was higher than that in adults (χ2=4.193,P=0.041).The level of serum uric acid in the CDI patients with HUA and disappearance of thirst was higher than those without disappearance of thirst (U=2.593,P=0.010).The multiple linear regression predicted serum creatinine (ß=0.472,95%CI=2.451-4.381,P<0.001) and body mass index (ß=0.387,95%CI=6.18-12.874,P<0.001) as the independent risk factors of serum uric acid level increment in children and adolescents,while serum creatinine (ß=0.361,95%CI=1.016-1.785,P<0.001),body mass index (ß=0.208,95%CI=2.321-6.702,P<0.001),triglyceride (ß=0.268,95%CI=12.936-28.840,P<0.001),and total cholesterol (ß=0.129,95%CI=2.708-22.250,P=0.013) were the independent risk factors in adults. Conclusions The patients with CDI were more likely to have HUA,and the prevalence of HUA in children and adolescents was higher than that in adults.Body mass index,serum creatinine,triglyceride,total cholesterol,and disappearance of thirst were the risk factors for the increased level of serum uric acid in CDI patients.

BACKGROUND: Cushing's disease (CD) is rare in pediatric patients. It is characterized by elevated plasma adrenocorticotropic hormone (ACTH) from pituitary adenomas, with damage to multiple systems and development. In recent years, genetic studies have shed light on the etiology and several mutations have been identified in patients with CD. CASE PRESENTATION: A girl presented at the age of 10 years and 9 months with facial plethora, hirsutism and acne. Her vision and eye movements were impaired. A quick weight gain and slow growth were also observed. Physical examination revealed central obesity, moon face, buffalo hump, supra-clavicular fat pads and bruising. Her plasma ACTH level ranged between 118 and 151 pg/ml, and sella enhanced MRI showed a giant pituitary tumor of 51.8 × 29.3 × 14.0 mm. Transsphenoidal pituitary debulk adenomectomy was performed and immunohistochemical staining confirmed an ACTH-secreting adenoma. Genetic analysis identified a novel germline GPR101 (p.G169R) and a somatic USP8 (p. S719del) mutation. They were hypothesized to impact tumor growth and function, respectively. CONCLUSIONS: We reported a rare case of pediatric giant pituitary ACTH adenoma and pointed out that unusual concurrent mutations might contribute to its early onset and large volume.

BACKGROUND AND AIMS: Neurotensin (NT) is a gut hormone with broad effects on the cardiovascular system. Recent data suggested that circulating proneurotensin (pro-NT)-the stable precursor fragment of NT-could independently predict cardiovascular artery disease (CAD) development. However, serum pro-NT levels in patients with premature cardiovascular artery disease (PCAD) are still unknown. This study aims to determine serum pro-NT levels in patients with PCAD and investigate its relationship with PCAD risk. METHODS AND RESULTS: A total of 490 subjects, including 364 with PCAD and 126 without PCAD (NPCAD), and 182 controls were enrolled in the study. Data of baseline clinical parameters and biochemical variables were collected. Serum pro-NT levels were measured by ELISA. Serum pro-NT levels were higher in patients with PCAD than in controls (59.42 ± 66.66 vs. 38.07 ± 48.48 pg/mL, P < 0.05), especially in patients with BMI<25 kg/m2. Serum pro-NT levels were independently related to PCAD (ß = 0.349, P < 0.001), and the association revealed a U-shaped curve characteristic between pro-NT tertiles and CAD risk in patients with premature CAD and controls. Subjects with low and high tertiles of pro-NT levels had 1.79-fold and 2.23-fold higher risks of PCAD, respectively, than subjects with median pro-NT levels (P < 0.05). After adjusting for age, gender, and BMI in Model 1 and other confounders in Model 2 and Model 3, the U-shaped relationship remained significant. CONCLUSION: Serum pro-NT levels were significantly increased in patients with PCAD. The association between pro-NT levels and PCAD risk presents a U-shaped curve characteristic, which demonstrated that subjects with lower and higher pro-NT levels both were more likely to have PCAD.

OBJECTIVE: To investigate the prevalence and possible factors influencing metabolic syndrome in people from Guizhou Province and to explore the predictive value of the fat-to-muscle ratio in diagnosing metabolic syndrome. METHODS: A multistage stratified sampling method was used in this cross-sectional study of 20-80 years old Han and Bouyei populations from Guizhou Province, southwestern China, from October-December 2012. The study included 4,553 cases of metabolic syndrome, that was defined according to 2005 International Diabetes Federation criteria. The receiver operating characteristic curve was used for determining the sensitivity, specificity, and predictive ability of the fat-to-muscle ratio for the diagnosis of metabolic syndrome. RESULTS: The age-standardized prevalence of metabolic syndrome was 11.38% (men: 9.76%; women: 12.72%) for Han and 4.78% (men: 4.43%; women: 5.30%) for Bouyei populations. In Guizhou Province, the cut-off value for the men fat-to-muscle ratio was 0.34, the area under the curve was 0.95, and the sensitivity and specificity were 0.94 and 0.85, respectively. The cut-off value for the women fat-to-muscle ratio was 0.55, the area under the curve was 0.91, and the sensitivity and specificity were 0.93 and 0.79, respectively. CONCLUSION: The fat-to-muscle ratio is highly predictive of metabolic syndrome in Guizhou Province, and a useful reference indicator.

Traumatic brain injury(TBI)is a major cause of hypothalamopituitary dysfunction. TBI-related hypothalamopituitary dysfunction is more common in the acute phase. Disturbance of pituitary/gonadal axis and growth hormone axis,as well as posterior pituitary dysfunction including central diabetes insipidus and syndrome of inappropriate antidiuretic hormone secretion,are the most frequently seen. During the chronic phase of TBI,anterior hypopituitarism is the major concern,which affects the quality of life. Risk factors for hypothalamopituitary dysfunction following TBI include low Glasgow score,high body mass index,hypoxia,older age,longer intensive care unit stay and longer coma status,radiological evidence of acute brain injury,and increased intracranial pressure. Children and adolescents are in a crucial period of growth and development,and therefore TBI-related pituitary dysfunction during this period can substantially affect the cognition and behaviors. There is currently no reliable biochemical marker predicting hypothalamopituitary dysfunctions. Therefore,it is of great importance to evaluate the pituitary function and take appropriate hormone replacement for moderate-severe TBI patients or mild TBI patients with apparent symptoms,especially for patients with water-electrolyte disturbance and adrenal deficiency. Growth hormone and gonadal hormone replacement therapies are crucial for children and adolescents.

Objective To evaluate the prevalence and clinical characteristics of obstructive sleep apnea (OSA) in bariatric surgery population.Methods Consecutive patients undergoing preoperative evaluation for bariatric surgery and referred for sleep monitoring in Peking Union Medical College Hospital from January 2009 to December 2015 were retrospectively analyzed. Age,gender,symptoms of snoring,fatigue,apnea and somnolence,apnea hyponea index (AHI),arterial blood gas,pulmonary function,sleep respiratory monitoring,positive airway therapy of OSA,and postoperative complications were recorded. The clinical characteristics of OSA groups at different severity were compared using AHI≥5 events/hour and AHI≥15 events/hour as cut-off values. Correlation analysis was applied to identify the clinical factors associated with AHI.Results Of 42 patients with complete sleeping monitoring data before bariatric surgery,30(71.4%) were diagnosed as OSA,14 (33.3%) were moderate or severe and 11 (26.2%) were severe. Also,OSA was not detected before the bariatric surgery in 25 cases (83.3%). Compared with patients with AHI<5 events/hour,patients with AHI≥5 events/hour had significantly older age (t=2.869,P=0.007),higher proportion of observed apnea (P=0.035),higher AHI (z=-4.592,P=0.000),higher proportion of night pulse oxygen saturation(SpO2) below 90% (z=-2.746,P=0.006),lower mean SpO2 (t=-2.071,P=0.046) and lower lowest SpO2 (t=-3.914,P=0.000). Compared with AHI<15 events/hour group,the AHI≥15 events/hour group had significantly higher BMI (t=2.281,P=0.043),male ratio (P=0.005),incidence of hypertension (P=0.011),proportion of observed apnea (P=0.001),percentage of smoking history (P=0.017),partial pressure of carbon dioxide(PaCO2)(t=3.478,P=0.002),AHI (z=-4.592,P=0.000),and proportion of night SpO2 below 90% (z=-4.530,P=0.000); in addition,the forced expiratory volume in one second(FEV1)% predicted (t=-3.377,P=0.002),forced vital capacity(FVC)% predicted (t=-2.342,P=0.026),night time mean SpO2 (t=-3.392,P=0.007),lowest SpO2 (t=-5.535,P=0.000) were significantly decreased. Correlation analysis showed that,in populations with normal PaCO2 (n=36),AHI was positively correlated with age (r=0.450,P=0.006) and BMI (r=0.384,P=0.021) and negatively correlated with FEV1% predicted (r=-0.457,P=0.008) and FVC% predicted (r=-0.432,P=0.013). Partial correlation analysis showed that,after age and BMI were adjusted,AHI was not correlated with FEV1% predicted(r=-0.287,P=0.125)and FVC%predicted(r=-0.241,P=0.200).Conclusion The incidence and underdiagnosis rate of OSA are high in bariatric surgery population. OSA should be routinely screened in bariatric population to reduce the postoperative complication.

Objective To analyze the effectiveness and safety of laparoscopic sleeve gastrectomy (LSG) in treating obesity and its co-morbidities.Methods The clinical data of obese patients undergoing LSG in Peking Union Medical College Hospital from August 2012 to August 2017 were retrospectively analyzed. Medium-term outcome measures included excess weight loss (%EWL),co-morbidity improvement,and complications.Results Seventy-five obese patients comprising 28 men[ body mass index(BMI):(47.3±7.5)kg/m 2) ] and 47 women [BMI (41.1±7.0) kg/m 2] were enrolled in this analysis. The common co-morbidities were liver dysfunction (53.3%),dyslipidemia (52.0%),obstructive sleep apnea (45.3%),type 2 diabetes mellitus (38.7%),and arterial hypertension (37.3%),which were improved by 75.0%,58.3%,83.3%,75.0% and 58.3% three years after surgery. The mean %EWL at 1,2,and 3 years after surgery was 81.6±34.7,80.9±30.2 and 79.7±30.8,respectively. The proportions of patients achieving successful weight loss were 81.7% (n=49),81.0% (n=34),and 79.3% (n=23) at 1,2,and 3 years (%EWL>50%). Early severe complications (Clavien-Dindo classification>2) occurred in 2.6% of patients,and the most common late complications was gastroesophageal reflux disease,which could be relieved by acid suppressants.Conclusion LSG is effective and safe in treating obesity and its co-morbidities.

Objective To evaluate physicians' attitude and knowledge about the management of adult growth hormone deficiency (AGHD) at Peking Union Medical College Hospital and impact factors associated with better decision-making.Methods A 21-question anonymous survey was distributed and collected at Peking Union Medical College Hospital, a major teaching hospital in Chinese Academy of Medical Sciences. Data of physicians' educational background, clinical training, patient workload per year and continuing medical education in AGHD were collected. Factors associated with appropriate answers were further analyzed by multivariate regression models.Results One hundred and eighteen internal medicine residents, endocrine fellows, attending physicians and visiting physicians responded to the survey. Among them, 44.9% thought that AGHD patients should accept recombinant human growth hormone replacement therapy. Moreover, 56.8% selected insulin tolerance test and growth hormone-releasing hormone-arginine test for the diagnosis of AGHD. Logistic regression analysis of physician demographic data, educational background, and work experience found no consistent independent factors associated with better decision-making, other than continued medical education, that were associated with treatment choice.Conclusions The physicians' reported management of AGHD in this major academic healthcare center in Beijing was inconsistent with current evidence. High quality continued medical education is required to improve Chinese physician management of AGHD.

Cushing's disease (CD) is a relatively rare disease,characterized by pathological hypercortisolism secondary to excessive adrenocorticotrophic hormone that is secreted by pituitary adrenocorticotrophic hormone adenoma or hyperplasia. In addition to the typical clinical symptoms such as moon face,buffalo hump,and central obesity,the CD patients may also experience mental disorders and cognitive dysfunction. This review mainly focuses on the cognitive state of CD patients,the mechanisms of cognitive impairment caused by high cortisol levels,and the imaging findings (especially magnetic resonance imaging) for the evaluation of cognitive functions.

Because of limited viral replication and lack of cytopathic effect in cell culture, a new PCR-based rapid seroneutralization assay for detection of GII.4 norovirus neutralized antibodies was developed with serum samples from acute-phase patients, convalescent-phase patients and healthy controls. According to this study, neutralizing antibodies were detected in 100% of convalescent-phase sera, and in 2.5% of healthy controls sera. However, all of the acute-phase serum samples could not neutralize virus efficiently. Compared to the results from ELISA (96.2% at sensitivity and 80% at specificity), the present in vitro neutralization assay is more specific and more sensitive.

Thyroid hormones (THs) play an important role in a wide range of crucial biological functions related to growth and development, and thyroid antibodies (TAs) can influence the biosynthesis of THs. Epidemiological studies have indicated that per- and polyfluoroalkyl substances (PFAS) could induce thyroid disruption, but studies on teenagers living in areas with high PFAS exposure are limited. This cross-sectional study focused on 836 teenagers (11- 15 years) living near a Chinese fluorochemical industrial plant. Decreased levels of free thyroxine (FT4, ﹤9.6 pmol/L, abnormal rate = 19.0 %) and elevated levels of free triiodothyronine (FT3, ï¹¥6.15 pmol/L, abnormal rate = 29.8 %) were observed. Correlations of serum PFAS concentrations and TAs/THs were analyzed. Increased PFOA was identified as a risk factor of decreased FT4 by using unadjusted (OR: 11.346; 95 % CI: 6.029, 21.352, p < 0.001) and adjusted (OR: 12.566; 95 % CI: 6.549, 24.115, p < 0.001) logistic regression models. In addition, significantly negative correlations were found between log10 transformed PFOA and FT4 levels using linear (unadjusted: ß = -1.543, 95 % CI: -1.937, -1.148, p < 0.001; adjusted: ß = -1.534, 95 % CI: -1.930, -1.137, p < 0.001) and BKMR models. For abnormal FT3, a significantly positive association between PFHxS and FT3 levels was observed in a regression model (unadjusted: ß = -0.903, 95 % CI: -1.212, -0.595, p < 0.001; adjusted: ß = -0.894, 95 % CI: -1.204, -0.583, p < 0.001), and PFHxS was identified as a risk factor (unadjusted: OR: 4.387; 95 % CI: 2.619, 7.346, p < 0.001; adjusted: OR: 4.527; 95 % CI: 2.665, 7.688, p < 0.001). Sensitivity analyses confirmed the robustness of the above results. This study reported the elevated PFAS exposure and thyroid function of teenagers living near a fluorochemical industrial plant from China.

PURPOSE: To retrospectively summarize the clinical features of acromegaly complicated with fulminant pituitary apoplexy and analyze the prognostic factors to guide early identification and timely treatment of such patients. METHODS: A retrospective analysis was carried out to summarize the clinical manifestations, hormone changes, imaging, treatment and follow-up of ten patients with acromegaly complicated with fulminant pituitary apoplexy admitted to our hospital from February 2013 to September 2021. RESULTS: The mean age of the ten patients (five males and five females) at the time of pituitary apoplexy was 37.1 ± 13.4 years old. There were nine cases with sudden severe headaches and five cases with visual impairment. All patients had pituitary macroadenomas, of which six cases with Knosp grade ≥3. The level of GH/IGF-1 hormone after pituitary apoplexy was lower compared with pre-apoplexy, and 1 patient reached biochemical remission spontaneously. Seven patients underwent transsphenoidal pituitary surgery after apoplexy and one patient was treated with long-acting somatostatin analog. The biochemical remission rate was 37.5% in eight patients immediately after treatment and 50% at the last follow-up. Patients with Knosp grade ≥3 were less likely to achieve biochemical remission than those with Knosp grade <3 (16.7% vs. 100%, p = 0.048), and patients who achieved biochemical remission had a smaller maximum tumor diameter [20.1 (20.1,28.0) mm vs. 44.0 (44.0,60) mm, p = 0.016]. CONCLUSION: Acromegaly complicated with fulminant pituitary apoplexy remains a diagnostic and therapeutic challenge.

Context: The high prevalence of hypothalamic obesity (HO) and dyslipidemia in individuals with craniopharyngioma (CP) following surgery is a cause for increasing concern. However, few studies have explored the lipid profile in pediatric CP patients, with inconsistent findings. In addition, the role of recombinant human growth hormone (rhGH) replacement remains unclear in these patients. Objective: To compare the blood lipid profile among post-operative craniopharyngioma children and adolescents with that among healthy controls and to reveal the effects of rhGH replacement. Methods: Data of 79 post-operative craniopharyngioma children and adolescents in our center were retrospectively collected. Sixty patients underwent rhGH replacement during the follow-ups. We selected 36 patients who received rhGH replacement therapy, while 20 patients received rhGH replacement for at least 1 year and had complete lipid data before and after treatment and compared them with 19 patients who did not receive rhGH replacement therapy. Results: Craniopharyngioma patients had higher total cholesterol (TC) (5.17 vs 3.77 mmol/L), triglyceride (TG) (1.51 vs 0.73 mmol/L), and low-density lipoprotein cholesterol (LDL-C) (3.14 vs 2.10 mmol/L), and lower high-density lipoprotein cholesterol (HDL-C) (1.06 vs 1.39 mmol/L) than controls (all p < 0.001). The lipid profile of obese and non-obese patients was not significantly different. After rhGH replacement, TC was 0.90 mmol/L lower (p = 0.002) and LDL-C was 0.73 mmol/L lower (p = 0.010) than baseline. Although the baseline LDL-C was higher, patients with rhGH replacement had lower LDL-C (-0.73 mmol/L adjusted for age and sex, p = 0.045) after the initiation of replacement compared with patients without rhGH replacement. Conclusion: The lipid profile of obese and non-obese children and adolescents with craniopharyngioma was unfavorable, and rhGH replacement could improve their lipid profile.
RESUMO
BACKGROUND: There is no appropriate tool to predict recombinant human growth hormone (rhGH) response before therapy initiation in short-stature children in late puberty. The current study aimed to explore the associations between magnetic resonance imaging (MRI) stages of the knee growth plates and rhGH response in short-stature children in late puberty. METHODS: In this prospective cohort study, short-stature children in late puberty were treated with rhGH and followed up for 6 months. We proposed a novel knee MRI staging system according to the growth plate states of distal femurs or proximal tibias and divided the participants into three groups: unclosed growth plate group, marginally closed growth plate group, and nearly closed growth plate group. The primary outcomes were height gain and growth velocity (GV), which were assessed three months later. RESULTS: Fifty participants were enrolled, including 23 boys and 27 girls. GV and height gain after 6 months of rhGH therapy decreased successively in the three groups with an increased degree of growth plate fusion, especially when grouped by proximal tibias (GV1-3 mon from 9.38 to 6.08 to 4.56 cm/year, GV4-6 mon from 6.75 to 4.92 to 3.25 cm/year, and height gain from 4.03 to 2.75 to 1.95 cm, all P < 0.001). Moreover, the MRI stages of growth plates independently served as a significant variable for GV and height gain after therapy, especially when grouped by proximal tibias (all P < 0.01). CONCLUSION: The MRI staging method is expected to be an effective tool for predicting rhGH response before therapy initiation in short-stature children in late puberty.
RESUMO
OBJECTIVE: To explore the clinical and magnetic resonance imaging (MRI) findings of pituitary hyperplasia due to primary hypothyroidism. METHOD: The clinical presentations, laboratory examinations, and MRI findings of 11 patients with pituitary hyperplasia secondary to primary hypothyroidism diagnosed at our hospitals from the beginning of 2008 to the end of 2011 were retrospectively reviewed. RESULTS: The clinical manifestations in 11 patients included growth arrest(7/8), mental retardation (6/8), cold intolerance and fatigue(6/11), slightly increased body weight (6/11), galactorrhea (3/11), paramenia (8/9), precocious puberty companying vaginal bleeding (2/2),and blurry vision (3/11). Laboratory investigations revealed grossly increased thyroid stimulating hormone, decreased thyroxine, and slightly elevated prolactin levels in all cases. Thyroid antibody was positive in six cases. On MRI, pituitary mass were detected a large intrasellar with/without suprasellar extension in all patients,showing the characteristic of symmetric enlargement. Spherical shape was viewed in 5 cases,with the height of (12.22 ± 3.12)mm. In the other 6 cases, the pituitary mass with the shape of calabash extended superiorly to suprasellar area, with a height of(18.95 ± 2.23)mm. The signal of pituitary mass was isointense to grey matter both on T1 weighted imaging and T2 weighted imaging. Bright short T1 signal in posterior lobe of pituitary was visible. Pituitary stalk was detected only in 4 cases from MRI without dislocation, while the width of pituitary stalk was within the normal limit. CONCLUSIONS: Pituitary hyperplasia should be considered when homogenous enlargement of the pituitary gland is found on MRI. The integration of MRI findings, clinical manifestations, and laboratory findings is helpful for the proper identification of the primary endocrine disease and thus avoid misdiagnosis.

OBJECTIVE: Ectopic adrenocorticotropic hormone (ACTH) syndrome (EAS) is a condition of hypercortisolism caused by non-pituitary tumors secreting ACTH. Appendiceal neuroendocrine tumor as a rare cause of ectopic ACTH syndrome was reported scarcely. We aimed to report a patient diagnosed with EAS caused by an appendiceal neuroendocrine tumor and summarized characteristics of these similar cases reported before. CASE REPORT AND LITERATURE REVIEW: We reported a case with Cushing's syndrome who was misdiagnosed as pituitary ACTH adenoma at first and accepted sella exploration. Serum and urinary cortisol decreased, and symptoms were relieved in the following 4 months after surgery but recurred 6 months after surgery. The abnormal rhythm of plasma cortisol and ACTH presented periodic secretion and seemingly rose significantly after food intake. EAS was diagnosed according to inferior petrosal sinus sampling (IPSS). Appendiceal mass was identified by 68Ga-DOTA-Tyr3-octreotate (DOTATATE)-PET-CT and removed. The pathological result was consistent with appendiceal neuroendocrine tumor with ACTH (+). The literature review demonstrated 7 cases diagnosed with EAS caused by appendiceal neuroendocrine tumor with similarities and differences. CONCLUSION: The diagnosis of an ectopic ACTH-producing tumor caused by the appendiceal neuroendocrine tumor can be a challenging procedure. Periodic ACTH and cortisol secretion may lead to missed diagnosis and misdiagnosis. IPSS is crucial in the diagnosis of EAS and 68Ga-DOTATATE-PET-CT plays an important role in the identification of lesions.

Objectives: To analyze and summarize the effect of SSA treatment on EAS due to p-NETs (EAS-p-NETs). Methods: Thirteen patients with EAS-p-NETs treated with SSAs at our center or described in the literature were included in this study. Clinical characteristics, laboratory data, imaging studies, histopathologic results, the effect of SSA treatment, and the prognosis of these EAS-p-NET patients were evaluated. Results: Four males and 9 females with an average age of 42.9 years were included in the study. The mean duration of follow-up was 38.8 ± 28.2 months. As one of the combined treatment measures, SSAs controlled the levels of ACTH and cortisol in 9 of the 13 patients (69.2%). Partial response was observed in 3 patients (23.1%), stable disease in 2 patients (15.4%), and progressive disease in 6 patients (46.2%). The median time to tumor progression was 24 months, and the median overall survival was 61 months. The side effects of SSA treatment included temporary mild abdominal pain, diarrhea, gallstones, and cholecystitis. Conclusions: As a supplemental therapy, SSA treatment led to clinical and biochemical improvement with a good safety profile in patients exhibiting EAS-p-NET with metastasis. However, tumor progression was inhibited by SSA treatment in only a few patients. Combined with other treatments, SSAs may improve the prognosis of patients with EAS-p-NETs.
