    甲状腺乳头状癌(PTC)是最常见的甲状腺恶性肿瘤,女性发病率增加。X染色体遗传的特定性状可能与PTC易感性的性别差异有关。这项研究的目的是调查两个X连锁基因的关联,叉头盒P3(FOXP3)和蛋白磷酸酶1调节亚基3F(PPP1R3F),具有PTC倾向和性别差异。研究中招募了136名PTC患者和同等数量的匹配健康志愿者。使用聚合酶链反应限制性片段长度多态性测定(PCR-RFLP)对rs3761548(FOXP3)和rs5953283(PPP1R3F)进行基因分型。使用组合亚硫酸氢盐限制性分析(COBRA)方法评估FOXP3的甲基化状态。采用SPSS软件进行统计分析。性别分层分析显示,仅在女性中,FOXP3rs3761548变体的CA和AA基因型以及A等位基因与PTC易感性有关。此外,PTC女性患者之间在FOXP3启动子位点观察到不同的甲基化状态,携带CA和CC基因型,和控制。两种显示的关联可以通过减少免疫相关血细胞中报道的FOXP3表达来解释女性中更高的PTC发生率。
    Papillary thyroid cancer (PTC) is the most common type of thyroid malignancy with an increased female incidence ratio. The specific traits of X chromosome inheritance may be implicated in gender differences of PTC predisposition. The aim of this study was to investigate the association of two X-linked genes, Forkhead Box P3 (FOXP3) and Protein Phosphatase 1 Regulatory Subunit 3F (PPP1R3F), with PTC predisposition and gender disparity. One hundred thirty-six patients with PTC and an equal number of matched healthy volunteers were enrolled in the study. Genotyping for rs3761548 (FOXP3) and rs5953283 (PPP1R3F) was performed using polymerase chain reaction-restriction fragment length polymorphism assay (PCR-RFLP). The methylation status of FOXP3 was assessed using the combined bisulfite restriction analysis (COBRA) method. The SPSS software was used for statistical analyses. Gender stratification analysis revealed that the CA and AA genotypes and the A allele of FOXP3 rs3761548 variant are associated with PTC predisposition only in females. Moreover, different methylation status was observed up to the promoter locus of FOXP3 between PTC female patients, carrying the CA and CC genotype, and controls. Both revealed associations may explain the higher PTC incidence in females through reducing FOXP3 expression as reported in immune related blood cells.

    背景:一些流行病学数据表明,在总体人群中,胆固醇水平与甲状腺癌风险之间可能存在反比关系。本研究旨在评估BethesdaIV类甲状腺结节患者的血脂分布。并比较良性和恶性结节之间是否有任何差异。
    方法:单中心,对204例接受部分或全甲状腺切除术切除BethesdaIV类甲状腺结节的受试者进行回顾性研究,在手术前12个月接受过血脂测试的人。除了血脂测量,其他人口,临床,收集生化和超声数据。
    结果:75名受试者(36.8%)在明确的组织病理学检查中被诊断为甲状腺癌。甲状腺癌患者的总胆固醇水平较低,LDL-胆固醇和非HDL-胆固醇比良性甲状腺疾病的受试者。HDL-胆固醇没有差异,甘油三酯或总胆固醇/HDL-胆固醇比率。在其他临床上,两组之间也没有差异,生化和超声变量,包括使用降脂药物。在多变量分析中,只有LDL-胆固醇与恶性肿瘤独立相关.滤泡性癌患者的胆固醇水平最低,而乳头状癌患者的价值介于滤泡状癌组和良性甲状腺疾病组之间。
    结论:在细胞学不确定的BethesdaIV类甲状腺结节的受试者中,总胆固醇水平,非HDL-胆固醇和,特别是,在患有恶性结节的人群中,LDL-胆固醇较低。
    BACKGROUND: Some epidemiological data suggest that there may be an inverse relationship between cholesterol levels and the risk of thyroid cancer in the overall population. The present study was aimed to evaluate the lipid profile specifically in subjects with Bethesda category IV thyroid nodules, and compare whether there were any differences between those with benign and malignant nodules.
    METHODS: Single-centre, retrospective study on 204 subjects treated by partial or total thyroidectomy for excision of a Bethesda category IV thyroid nodule, who had undergone a blood lipid profile test in the 12 months prior to surgery. In addition to lipid measures, other demographic, clinical, biochemical and ultrasound data were collected.
    RESULTS: Seventy-five subjects (36.8%) were diagnosed with thyroid carcinoma in the definitive histopathological examination. Patients with thyroid cancer had lower levels of total cholesterol, LDL-cholesterol and non-HDL-cholesterol than subjects with benign thyroid diseases. There were no differences in HDL-cholesterol, triglycerides or total cholesterol/HDL-cholesterol ratio. There were no differences either between groups in other clinical, biochemical and ultrasound variables, including the use of lipid-lowering drugs. In multivariate analysis, only LDL-cholesterol was independently associated with malignancy. Subjects with follicular carcinoma showed the lowest cholesterol levels, while those with papillary carcinoma had intermediate values between the group with follicular carcinoma and the group with benign thyroid diseases.
    CONCLUSIONS: In subjects with cytologically indeterminate Bethesda category IV thyroid nodules, levels of total cholesterol, non-HDL-cholesterol and, particularly, LDL-cholesterol are lower among those with malignant nodules.

    In solid tumors, hypereosinophilia is a rare phenomenon and is mainly associated with mucin-secreting carcinomas. Thyroid tumors associated with neutrophilia and/or eosinophilia have been described exclusively in patients with anaplastic thyroid cancer. Eosinophilia associated with papillary thyroid cancer is extremely rare and there are very few cases currently described. It has been suggested that three cytokines, namely interleukin-3 (IL-3), interleukin-5 (IL-5), and granulocyte-macrophage colony-stimulating factor (GM-CSF), may act as a peptide potential eosinophilic. To date, only three patients with differentiated thyroid cancer associated with eosinophilia have been reported, two of the papillary type and one of the medullary type. A 48-year-old patient consulted in 2022 due to bilateral cervical lymphadenopathy of 3 years\' duration associated with wasting syndrome and hypereosinophilia. PET CT was requested, which showed hypermetabolic focus in the right thyroid lobe and lymph node, lung, bone, and liver metastases; Thyroid ultrasound showing a nodule of high suspicion of malignancy and a conglomerate of lymphadenopathy in the right lobe with positive needle wash for thyroglobulin. Hypereosinophilia was evaluated with initial leukocytosis values of GB 30,310/mm3 (10,608/mm3 of eosinophils) to maximum values of GB 77,090/mm3 (eosinophils 20,814/mm3). It was interpreted as paraneoplastic syndrome and corticosteroid therapy was started at immunosuppressive doses without response. Our observations presented in this article are in line with most studies reflecting that paraneoplastic hypereosinophilia is characterized by more advanced disease and poor prognosis.
    En los tumores sólidos la hipereosinofilia es un fenómeno raro y se asocia principalmente con carcinomas secretores de mucina. Los tumores tiroideos asociados a neutrofilia y/o eosinofilia se han descrito exclusivamente en pacientes con cáncer anaplásico de tiroides. La eosinofilia asociada con cáncer papilar de tiroides es extremadamente rara y se encuentran muy pocos casos descriptos actualmente. Se ha sugerido que tres citocinas, a saber, la interleucina-3 (IL-3), la interleucina-5 (IL-5) y el factor estimulante de colonias de granulocitos y macrófagos (GM-CSF), pueden actuar como un péptido eosinofílico potencial. Hasta el momento solo se han reportado tres pacientes con cáncer diferenciado de tiroides asociados a eosinofilia, dos de tipo papilar y uno de tipo medular. Paciente de 48 años consultó en el año 2022 por adenopatías cervicales bilaterales de 3 años de evolución asociado a síndrome consuntivo e hipereosinofilia. Se solicitó PET CT que evidenció foco hipermetabólico en lóbulo tiroideo derecho y metástasis ganglionares, pulmonares, óseas y hepáticas; ecografía tiroidea que evidencia en lóbulo derecho nódulo de alta sospecha de malignidad y conglomerado de adenopatías con lavado de aguja positivo para tiroglobulina. Evaluada la hipereosinofilia con valores iniciales de leucocitosis de GB 30310/mm3 (10608/mm3 de eosinófilos) hasta valores máximos de GB 77090/mm3 (eosinófilos 20814/mm3) se interpretó como síndrome paraneoplásico y se inició corticoterapia en dosis inmunosupresoras sin respuesta. Nuestras observaciones presentadas en este artículo están en línea con la mayoría de los estudios que reflejan que la hipereosinofilia paraneoplásica se caracteriza por una enfermedad más avanzada y un mal pronóstico.

    背景与目的:胰腺实性假乳头状瘤(SPN),一种主要影响年轻女性的罕见肿瘤,由于影像学和流行病学知识的改善,发病率增加。本研究旨在了解不同干预措施的结果,可能的并发症,和相关的危险因素。材料和方法:本研究回顾性分析了1998年9月至2020年7月期间接受SPN胰腺手术的24例患者。结果:手术干预,通常需要有症状的病例或病理证实,结果良好,5年生存率高达97%.尽管在标准化术前评估和随访方案方面存在挑战,侵袭性完全切除显示有希望的长期生存率和良好的肿瘤结局.值得注意的是,常规手术和微创(MI)手术的围手术期结局无显著差异.预后和位置缺乏组织病理学相关性。在患者中,1例患者术后41个月出现弥漫性肝转移,但化疗和肝动脉化疗栓塞反应良好,术后159个月观察到疾病稳定性。另一位患者在手术后发展为非酒精性脂肪性肝炎,并接受了肝移植,手术后115个月屈服于不良的药物依从性。结论:这些发现强调了手术干预在管理SPN中的重要性,并建议MI方法是一种可行的选择,其结果与常规手术相当。
    Background and Objectives: The pancreatic solid pseudopapillary neoplasm (SPN), a rare tumor predominantly affecting young women, has seen an increased incidence due to improved imaging and epidemiological knowledge. This study aimed to understand the outcomes of different interventions, possible complications, and associated risk factors. Materials and Methods: This study retrospectively analyzed 24 patients who underwent pancreatic surgery for SPNs between September 1998 and July 2020. Results: Surgical intervention, typically required for symptomatic cases or pathological confirmation, yielded favorable outcomes with a 5-year survival rate of up to 97%. Despite challenges in standardizing preoperative evaluation and follow-up protocols, aggressive complete resection showed promising long-term survival and good oncological outcomes. Notably, no significant differences were found between conventional and minimally invasive (MI) surgery in perioperative outcomes. Histopathological correlations were lacking in prognosis and locations. Among the patients, one developed diffuse liver metastases 41 months postoperatively but responded well to chemotherapy and transcatheter arterial chemoembolization, with disease stability observed at 159 postoperative months. Another patient developed nonalcoholic steatohepatitis after surgery and underwent liver transplantation, succumbing to poor medication adherence 115 months after surgery. Conclusions: These findings underscore the importance of surgical intervention in managing SPNs and suggest the MI approach as a viable option with comparable outcomes to conventional surgery.

    获得切缘阴性切除对胰腺实性假乳头状瘤(SPN)的治疗至关重要,在儿科病例中,在远端胰腺切除术期间保留脾脏是非常理想的。当肿瘤累及脾血管使保存复杂化时,腹腔镜Warshaw手术(Lap-WT)是无价的。然而,Lap-WT在儿科患者中的可行性仍存在争议。这项研究介绍了三例接受Lap-WT的小儿SPN病例的临床结果。中位年龄为10岁,中位肿瘤大小为50毫米。Lap-WT显示出成功的结果,中位手术时间为311分钟,失血量为12mL。术后无并发症发生,平均住院时间为8天。长期随访显示2例轻度血小板减少,脾脏体积增大,胃周静脉曲张合二为一,无出血并发症。没有观察到肿瘤复发的实例。Lap-WT成为儿科SPN的可行方法,确保保存脾脏而不损害肿瘤预后。
    Achieving margin-negative resection is crucial in treatment of solid pseudopapillary neoplasm (SPN) of the pancreas, while preserving the spleen during distal pancreatectomy is highly desirable in pediatric cases. Laparoscopic Warshaw procedure (Lap-WT) is invaluable when tumor involvement in splenic vessels complicates preservation. However, the feasibility of Lap-WT in pediatric patients remains contentious. This study presents the clinical outcomes of three pediatric SPN cases who underwent Lap-WT. The median age was 10 years, with a median tumor size of 50 mm. Lap-WT demonstrated successful outcomes with a median operation time of 311 min and blood loss of 12 mL. No postoperative complications occurred, with a median length of hospital stay of 8 days. Long-term follow-up showed mild thrombocytopenia and increased spleen volume in two cases, perigastric varices in one, with no bleeding complications. No instances of tumor recurrence were observed. Lap-WT emerges as a feasible approach for pediatric SPN, ensuring spleen preservation without compromising oncological outcomes.

    目的:本研究旨在确定BRAFV600E和TERT突变在甲状腺乳头状癌(PTC)患者颈部淋巴结(LN)转移发生率中的作用。
    方法:这是一项横断面研究,涉及CiptoMangunkusumo医生医院的PTC患者,雅加达。数据是根据病历回顾性获得的,除了BRAFV600E和TERT启动子突变。PTC患者的肿瘤组织标本被转移到医学院综合实验室,印度尼西亚大学。用KOD一PCR主混合(ToyoboKMM-201)进行BRAF基因增殖,而TERT基因增殖用PCRMasterMix进行。使用SPSS版本20进行数据分析。使用卡方检验的单变量和双变量分析对数据进行分析。
    结果:42例PTC患者纳入研究;19例(45%)有BRAF突变,20(48%)有TERT突变,20例(48%)有LN转移。BRAFV600E突变与LN转移相关[p<0.001,OR=25.33(95%CI4.92-130.34)],而TERT突变没有。BRAF+和TERT-突变患者发生LN转移的可能性是BRAF-和TERT-突变患者的18.00倍(95%CI2.01-161.05)。此外,TERT突变和BRAF突变的存在使风险比BRAF-和TERT-患者高60.00(95%CI4.72-763.04).
    结论:BRAF突变与PTC患者的LN转移有关,但不是TERT突变。然而,有BRAF突变的PTC患者中TERT突变的存在增加了LN转移的风险。
    OBJECTIVE: This study was designed to determine the role of BRAF V600E and TERT mutations in the incidence of neck lymph node (LN) metastasis in patients with papillary thyroid carcinoma (PTC).
    METHODS: This was a cross-sectional study, involving PTC patients at Dr. Cipto Mangunkusumo Hospital, Jakarta. Data were obtained retrospectively based on medical records, except for BRAF V600E and TERT promoter mutations. Tumor tissue specimens of PTC\'s patients were transferred to the Integrated Laboratory of Faculty of Medicine, Universitas Indonesia. BRAF gene multiplication was performed with KOD One PCR Master Mix (Toyobo KMM-201), while TERT gene multiplication was performed with PCR Master Mix. Data analysis was performed with SPSS version 20. The data were analyzed using univariate and bivariate analysis with the Chi-Square test.
    RESULTS: 42 PTC patients were included in the study; 19 (45%) had BRAF mutation, 20 (48%) had TERT mutation, and 20 (48%) had LN metastases. BRAF V600E mutation was associated with LN metastasis [p<0.001, OR = 25.33 (95% CI 4.92 - 130.34)], while TERT mutation was not. Patients with BRAF+ and TERT- mutations were 18.00 times (95% CI 2.01 - 161.05) more likely to develop LN metastasis than patients with BRAF- and TERT-. Furthermore, the presence of TERT mutation along with BRAF mutation increased the risk to 60.00 (95% CI 4.72 - 763.04) higher than patients with BRAF- and TERT-.
    CONCLUSIONS: BRAF mutation was associated with LN metastasis in PTC patients, but not TERT mutations. However, the presence of TERT mutation in PTC\'s patients with BRAF mutation increased the risk of LN metastasis.

    方法:该研究由80名受试者组成,分为病例(20名DTC受试者和20名BC受试者)和对照(40名受试者)。晨尿或斑点尿用于UIC测量。
    结果:在甲状腺癌中,UIC患者和对照组的中位数为195.45±133.61µg/L和145±39.64µg/L,分别,p=0.33PTC受试者的UIC中位数明显高于FTC受试者,227.12±130.98μg/L与68.75±22.95μg/L,p=0.00,甲状腺乳头状癌与尿中高碘排泄密切相关,应急系数(c)=0.722。在BC患者中,不管亚型,乳腺癌患者的碘排泄水平明显降低.UIC患者和对照组的中位数分别为80.05±38.24µg/L和144.25±36.79µg/L,分别,p=0.000。
    结论:碘尿浓度与DTC组织病理学类型密切相关,在BC科目中,与对照相比,IUC显著较低。
    Iodine intake can affect thyroid and breast cells, and urinary iodine concentration (UIC) is an effective biomarker for iodine intake.
    OBJECTIVE: This study aimed to analyze the correlation between urinary iodine concentration in differentiated thyroid cancer (DTC) and breast cancer (BC) subjects.
    METHODS: The study consisted of 80 subjects divided into case (20 DTC and 20 BC subjects) and control (40 subjects). Morning urine or spot urine was used for UIC measurement.
    RESULTS: In thyroid cancer, UIC median patients and controls were 195.45 ± 133.61 µg/L and 145 ± 39.64 µg/L, respectively, with p =0.33. The UIC median of PTC subjects was significantly higher compared to FTC subjects, 227.12±130.98 μg/L versus 68.75±22.95 μg/L, p=0.00, and papillary thyroid cancer is closely related to a high iodine excretion in urine with contingency coefficient  (c)=0.722. In BC patients, regardless of subtypes, breast cancer subjects showed a significantly lower iodine excretion level. The median of UIC patients and controls were 80.05 ± 38.24 µg/L and 144.25 ± 36.79 µg/L, respectively, p=0.000.
    CONCLUSIONS: Iodine urine concentrations strongly correlate with the type of DTC histopathology, and in BC subjects, IUC was significantly lower compared to the control.
