    背景:甲状腺粘液表皮样癌(MEC)占所有甲状腺肿瘤的不到0.5%。甲状舌管囊肿癌是一种罕见的疾病,仅报道了约300例。
    方法:一名34岁妊娠37周时因原发性自身免疫性甲状腺功能减退症到内分泌中心就诊的孕妇。甲状腺超声显示为假结节。两年后对患者进行了随访。她报告了足月分娩,没有并发症。进行了新的甲状腺超声检查,显示甲状腺上正中区域的囊性病变,测量6x9x10毫米,以前没有报道过。4个月后,甲状腺上囊性病变经甲状腺超声证实,测量6x11x12毫米。患者转诊接受细针穿刺细胞学检查。细胞学检查显示淋巴细胞,红细胞,以及一些具有大细胞质的上皮聚集体和具有亲氧性的核多元结构。患者接受了甲状腺上病变的Sistrunk手术。组织学检查显示,异位甲状腺组织中存在淋巴细胞性甲状腺炎,细胞巢实性。表皮样上皮,粘液分泌细胞提示低度粘液表皮样癌。免疫组织化学研究为阳性,显示甲状腺转录因子1和细胞角蛋白19。未观察到甲状腺球蛋白阳性,降钙素,半乳糖凝集素-3和HectorBattifora间皮抗原1。最近的后续检查,手术后13个月,已发现疾病复发阴性。
    结论:这是甲状舌管内发生MEC的首例病例。考虑到病人的年龄,组织学诊断,甲状腺结节和转移的缺失,我们决定在没有全甲状腺切除术的情况下进行Sistrunk手术。
    BACKGROUND: Mucoepidermoid Carcinoma (MEC) of the thyroid represents less than 0.5% of all thyroid neoplasms. Thyroglossal duct cyst carcinoma is a rare condition with only approximately 300 cases reported.
    METHODS: A 34-year-old pregnant woman at 37 weeks gestation presented to an endocrinological center for primary autoimmune hypothyroidism. The thyroid ultrasound revealed a pseudonodular pattern. The patient was followed up after two years. She reported a full-term delivery without complications. A new thyroid ultrasound was performed, showing a cystic lesion in the median suprathyroid area, measuring 6 x 9 x 10 mm, not previously reported. After 4 months, the suprathyroid cystic lesion was confirmed by thyroid ultrasound, measuring 6 x 11 x 12 mm. The patient was referred for fine-needle aspiration cytology. Cytological examination showed lymphocytes, red blood cells, and some epithelial aggregates with large cytoplasm and nuclear polymetrism with oxyphilic aspects. The patient underwent the Sistrunk procedure for the suprathyroid lesion. The histological examination revealed lymphocytic thyroiditis in heterotopic thyroid tissue with solid cell nest, epidermoid epithelium, and mucus-secreting cells suggestive of low-grade mucoepidermoid carcinoma. The immunohistochemistry study was positive, exhibiting thyroid transcription factor 1 and cytokeratin-19. No positivity was observed for thyroglobulin, calcitonin, galectin-3, and Hector Battifora mesothelial antigen 1. The recent follow-up examination, 13 months after the surgery, has been found negative for disease recurrence.
    CONCLUSIONS: This is the first case of an MEC occurring within a thyroglossal duct. Considering the age of the patient, the histological diagnosis, and the absence of thyroid nodules and metastasis, we decided on the Sistrunk procedure without total thyroidectomy.

    当被长期忽视时,唾液腺多形性腺瘤(PA)可以达到相当大的大小,随着恶性转化的风险增加患者的发病率。很少有病例报告描述腮腺的PA表现为巨大的颈面部肿块。我们报告了一例上皮肌上皮癌-一种罕见的非管腔分化癌ex-PA(Ca-Ex-PA)亚型,在腮腺的原发性PA中长期发展,并表现为巨大的颈面部肿块。
    When neglected for a long time, salivary gland pleomorphic adenoma (PA) can attain a considerable size, increasing the patient\'s morbidity along with the risk of malignant transformation. Very few case reports are available describing PA of the parotid glands presenting as a large cervicofacial mass. We report a case of epithelial myoepithelial carcinoma -a rare subtype of carcinoma ex-PA (Ca-Ex-PA) of non-luminal differentiation, that developed over a long period in a primary PA of the parotid gland and presented as a giant cervicofacial mass.

    目的:对于雌激素受体阳性(ER+)/人表皮生长因子受体2阴性(HER2-)的早期乳腺癌患者,ODX(ODX)可预测其复发风险和增加化疗的益处。我们旨在使用现成的临床病理参数开发简化的评分系统,以预测高风险ODX复发评分(RS),同时最大程度地减少有关Ki-67指数评估方法的可重复性问题。
    方法:我们招募了300例ER+/HER2-早期乳腺癌患者,测试集中有ODXRS数据的人。使用QuPath图像分析平台,我们系统地评估了平均值,,热点和测试集中最热门的Ki-67分数。采用Logistic回归分析建立高危ODXRS的预测评分系统。建立了一个独立的验证集,包括不同时期的117名患者。
    结果:年龄≤50岁等因素,浸润性导管癌肿瘤类型,组织学2级或3级,肿瘤坏死,孕激素受体阴性,Roche分析的Ki-67评分高(>20)与高风险ODXRS相关。这些变量被纳入我们的评分系统。评分系统的曲线下面积为0.8057。当应用于截止值为3的测试集和验证集时,我们的评分系统的灵敏度为92%。
    结论:我们成功开发了一种基于Ki-67评分方法系统评价的评分系统。我们相信,我们的用户友好的高风险ODXRS预测评分系统可以帮助临床医生识别可能或可能需要额外ODX测试的患者。
    OBJECTIVE: Oncotype DX (ODX) predicts the risk of recurrence and benefits of adding chemotherapy for patients with estrogen receptor positive (ER+)/human epidermal growth factor receptor 2 negative (HER2-) early-stage breast cancer. We aimed to develop a simplified scoring system using readily available clinicopathological parameters to predict a high-risk ODX recurrence score (RS) while minimizing reproducibility issues regarding Ki-67 index evaluation methods.
    METHODS: We enrolled 300 patients with ER+/HER2- early breast cancer, for whom ODX RS data were available in the test set. Using the QuPath image analysis platform, we systematically evaluated the average, hotspot, and hottest spot Ki-67 scores in the test set. Logistic regression analyses were conducted to establish a predictive scoring system for high-risk ODX RS. An independent validation set comprising 117 patients over different periods was established.
    RESULTS: Factors such as age ≤ 50 years, invasive ductal carcinoma tumor type, histologic grade 2 or 3, tumor necrosis, progesterone receptor negativity, and a high Roche-analyzed Ki-67 score (> 20) were associated with high-risk ODX RS. These variables were incorporated into our scoring system. The area under the curve of the scoring system was 0.8057. When applied to both the test and validation sets with a cutoff value of 3, the sensitivity of our scoring system was 92%.
    CONCLUSIONS: We successfully developed a scoring system based on the systematic evaluation of Ki-67 scoring methods. We believe that our user-friendly predictive scoring system for high risk ODX RS could help clinicians in identifying patients who may or may require additional ODX testing.

    这项研究确定了手术前腹部MRI对切除PDAC患者全因死亡率的影响。
    2011年1月至2022年12月在安大略省接受胰腺切除术的所有成人(≥18岁)PDAC患者,加拿大,为这项基于人群的队列研究确定(ICD-O-3代码:C250,C251,C252,C253,C257,C258)。患者人口统计学,合并症,PDAC级,医疗和外科管理,生存数据来自ICES多个链接的省级行政数据库。在控制多个协变量后,比较了有和没有手术前腹部MRI的患者的全因死亡率。
    4579名患者的队列包括2432名男性(53.1%)和2147名女性(46.9%),平均年龄为65.2岁(标准差:11.2岁);2998人(65.5%)死亡,1581人(34.5%)存活。切除术后的中位随访时间为22.4个月(四分位距:10.8-48.8个月),胰腺切除术后中位生存期为25.9个月(95%置信区间[95%CI]:24.8,27.5).接受术前腹部MRI检查的患者的中位生存期为33.1个月(95%CI:30.7,37.2),而其他所有患者的中位生存期为21.1个月(95%CI:19.8,22.6)。共有2354/4579(51.4%)患者接受了术前腹部MRI检查,这与全因死亡率下降17.2%(95%CI:11.0,23.1)有关,调整后的风险比(aHR)为0.828(95%CI:0.769,0.890)。
    术前腹部MRI与接受胰腺切除术的PDAC患者的总生存率提高相关,可能是由于肝转移比CT更好的检测。

    UNASSIGNED: This study determined the impact of pre-operative abdominal MRI on all-cause mortality for patients with resected PDAC.
    UNASSIGNED: All adult (≥18 years) PDAC patients who underwent pancreatectomy between January 2011 and December 2022 in Ontario, Canada, were identified for this population-based cohort study (ICD-O-3 codes: C250, C251, C252, C253, C257, C258). Patient demographics, comorbidities, PDAC stage, medical and surgical management, and survival data were sourced from multiple linked provincial administrative databases at ICES. All-cause mortality was compared between patients with and without a pre-operative abdominal MRI after controlling for multiple covariates.
    UNASSIGNED: A cohort of 4579 patients consisted of 2432 men (53.1%) and 2147 women (46.9%) with a mean age of 65.2 years (standard deviation: 11.2 years); 2998 (65.5%) died while 1581 (34.5%) survived. Median follow-up duration post-resection was 22.4 months (interquartile range: 10.8-48.8 months), and median survival post-pancreatectomy was 25.9 months (95% confidence interval [95% CI]: 24.8, 27.5). Patients who underwent a pre-operative abdominal MRI had a median survival of 33.1 months (95% CI: 30.7, 37.2) compared to 21.1 months (95% CI: 19.8, 22.6) for all others. A total of 2354/4579 (51.4%) patients underwent a pre-operative abdominal MRI, which was associated with a 17.2% (95% CI: 11.0, 23.1) decrease in the rate of all-cause mortality, with an adjusted hazard ratio (aHR) of 0.828 (95% CI: 0.769, 0.890).
    UNASSIGNED: Pre-operative abdominal MRI was associated with improved overall survival for PDAC patients who underwent pancreatectomy, possibly due to better detection of liver metastases than CT.

    胃癌是世界上癌症相关死亡的第五大原因。在没有胃肠道(GI)症状的胃癌中发生骨转移(BM)是一种罕见的现象,在现有文献中偶尔有记录。我们报告了一例27岁的男性,表现出严重背痛的主诉一个月。上消化道内镜和活检后,癌症的主要来源被确定为孤立的胃腺癌,支持在脊柱磁共振成像(MRI)上诊断骨转移。患者计划开始姑息化疗(5-氟尿嘧啶,亚叶酸,奥沙利铂,和多西他赛{FLOT}方案)与20Gy的姑息性放疗,分五个部分进行骨转移。患者拒绝治疗,并在医疗建议下出院。
    Gastric cancer is the fifth leading cause of cancer-related deaths in the world. The occurrence of bone metastases (BM) in gastric cancer without prior gastrointestinal (GI) symptoms is a rare phenomenon that has been sporadically documented in the existing literature. We report a case of a 27-year-old male presenting with chief complaints of severe backache for one month. After an upper gastrointestinal endoscopy and biopsy, the primary source of cancer was identified as a solitary gastric adenocarcinoma, supporting the diagnosis of bony metastases on the magnetic resonance imaging (MRI) of the spine. The patient was planned to start on palliative chemotherapy (5-fluorouracil, leucovorin, oxaliplatin, and docetaxel {FLOT} regimen) with palliative radiotherapy of 20 Gy in five fractions to bony metastasis. The patient denied treatment and was discharged against medical advice.

    最近的几项研究已经调查了在各种癌症中使用大分割放射治疗(HFRT)。然而,由于担心严重的副作用和缺乏改善治疗结果的证据,有或没有同步化疗的非小细胞肺癌(NSCLC)的HFRT尚未广泛使用。HFRT与NSCLC同步化疗的调查通常在单臂研究中进行,并与少数患者。所以还没有足够的数据。因此,韩国放射肿瘤学学会实践指南委员会计划这篇综述文章总结到目前为止关于HFRT的证据,并提供给放射肿瘤学临床医师.总之,HFRT已经证明了有希望的结果,审查的数据支持其治疗局部晚期NSCLC的可行性和相当的疗效.食管毒性的发生率和严重程度已被确定为主要问题,特别是在处理大部分尺寸时。Strategies,比如食道保留技术,图像指导,和剂量限制,可以帮助缓解这个问题,提高治疗的耐受性。持续的研究和临床试验对于完善治疗策略至关重要,确定最佳患者选择标准,并提高治疗效果。
    Several recent studies have investigated the use of hypofractionated radiotherapy (HFRT) for various cancers. However, HFRT for non-small cell lung cancer (NSCLC) with or without concurrent chemotherapy is not yet widely used because of concerns about serious side effects and the lack of evidence for improved treatment results. Investigations of HFRT with concurrent chemotherapy in NSCLC have usually been performed in single-arm studies and with a small number of patients, so there are not yet sufficient data. Therefore, the Korean Society for Radiation Oncology Practice Guidelines Committee planned this review article to summarize the evidence on HFRT so far and provide it to radiation oncology clinicians. In summary, HFRT has demonstrated promising results, and the reviewed data support its feasibility and comparable efficacy for the treatment of locally advanced NSCLC. The incidence and severity of esophageal toxicity have been identified as major concerns, particularly when treating large fraction sizes. Strategies, such as esophagus-sparing techniques, image guidance, and dose constraints, may help mitigate this problem and improve treatment tolerability. Continued research and clinical trials are essential to refine treatment strategies, identify optimal patient selection criteria, and enhance therapeutic outcomes.

    一旦胆固醇沉积在动脉壁旁边,动脉内胆固醇浓度的增加就会阻塞动脉血流。这导致动脉粥样硬化。致癌导致血管胆固醇的更快清除以满足肿瘤细胞发育的需要。两种疾病都有血液中促炎细胞因子的浓度增加。探讨胆固醇和促炎细胞因子在动脉粥样硬化和癌变发病中的比较特征。使用MEDLINE进行的全面在线调查,Scopus,PubMed,GoogleScholar在动脉粥样硬化和癌症患者中进行了相关期刊的关键搜索词胆固醇和细胞因子。据报道,与高胆固醇血症相关的血脂异常导致动脉粥样硬化,细胞核中的高胆固醇血症是发生癌变的原因。还注意到促炎细胞因子参与上述两种发病机理。抗炎细胞因子的变化只是每种的特征。因此,胆固醇和促炎细胞因子在动脉粥样硬化和致癌后果的发生中紧密相关。
    An increase of cholesterol concentration within the artery obstructs arterial blood flow once it deposits alongside the arterial wall. This results in atherosclerosis. Carcinogenesis causes a quicker clearance of vascular cholesterol to meet the demands of tumour cell development. Both illnesses have an increased concentration of pro-inflammatory cytokines in the blood. To search the comparative characteristics of cholesterol and pro-inflammatory cytokines in the pathogenesis of atherosclerosis and carcinogenesis, a comprehensive online survey using MEDLINE, Scopus, PubMed, and Google Scholar was conducted for relevant journals with key search term cholesterol and cytokines in atherosclerotic and cancerous patients. According to reports, hypercholesterolaemia related dyslipidemia causes atherosclerosis in blood arteries and hypercholesterolaemia in cell nucleus is a reason for developing carcinogenesis. It is also noted that pro-inflammatory cytokines are involved in both of the aforementioned pathogenesis. Changes in anti-inflammatory cytokines are only the characteristic features of each kind. Thus, Cholesterol and pro-inflammatory cytokines are intensely interlinked in the genesis of atherosclerotic and carcinogenic consequences.

    背景与目的:乳腺分泌癌是一种少见的乳腺癌组织学亚型。关于这个实体的研究很少,只有一些更大的研究,缺乏共识。我们的目的是报告该亚型中特定的顶腺分泌分化,并考虑该病例的临床结果。病例介绍:我们报告了一名72岁女性患者的病例,该患者到我院就诊,患有可疑的乳腺肿瘤。核心活检和乳房切除术显示低度乳腺癌,一种分泌型亚型,具有大汗腺分化。免疫组织化学证实了肿瘤细胞的分泌性质和大汗腺性质。手术切除被认为是治愈性的,患者正在接受任何复发的长期监测。结论:对分泌性癌伴大汗腺分化的临床行为研究甚少。临床结果未知,不幸的是,除了手术,没有其他辅助治疗显示出疗效.对于这种罕见的实体,需要对长期临床进展进行进一步研究。
    Background and Objectives: Secretory carcinoma of the breast is an uncommon histological subtype of breast cancer. There is little research on this entity and only a few larger studies, which lack consensus. We aim to report a particular apocrine differentiation in this subtype and ponder upon the clinical outcome of this case. Case presentation: We report the case of a 72-year-old female patient who presented to our hospital with a suspicious breast tumor. Core biopsy and mastectomy showed a low-grade breast carcinoma, a secretory subtype with apocrine differentiation. Immunohistochemistry confirmed both the secretory nature and the apocrine nature of the tumor cells. Surgical excision was considered curative and the patient is under long-term surveillance for any recurrences. Conclusions: There is very little research on the clinical behavior of secretory carcinomas with apocrine differentiation. The clinical outcome is unknown and, unfortunately, besides surgery, no other adjuvant treatments have shown efficacy. Further studies on long-term clinical progression are required for this rare entity.

    影响异柠檬酸脱氢酶2(IDH2)基因的密码子172的突变定义了鼻窦未分化癌(SNUCs)的一个亚组,具有相对良好的预后和全球高甲基化表型。它们也在神经胶质瘤中复发(连同IDH1突变),急性髓系白血病,和肝内胆管癌。通常报道的突变,所有这些都与异常的IDH2酶活性有关,包括R172K,R172S,R172T,R172G,和R172M。我们介绍了一个SNUC的病例,该病例具有从未描述过的IDH2突变,R172A.我们的报告将我们样本的甲基化模式与来自基因表达综合数据库的其他病例进行了比较。分层聚类表明我们的样品与其他IDH突变体SNUCs之间存在很强的关联,并且在鼻窦正常组织和肿瘤之间存在明显的区别。主成分分析(PCA),使用100个主成分解释94.5%的方差,显示我们样品的位置在其他IDH突变体SNUC的1.02标准偏差内。IDH2R172A与其他R172变体的分子建模分析提供了它们如何影响蛋白质活性位点的结构解释。因此,我们的发现表明,IDH2中的R172A突变赋予了与IDH2中其他R172突变相似的功能,从而产生了相似的高甲基化谱。
    Mutations affecting codon 172 of the isocitrate dehydrogenase 2 (IDH2) gene define a subgroup of sinonasal undifferentiated carcinomas (SNUCs) with a relatively favorable prognosis and a globally hypermethylated phenotype. They are also recurrent (along with IDH1 mutations) in gliomas, acute myeloid leukemia, and intrahepatic cholangiocarcinoma. Commonly reported mutations, all associated with aberrant IDH2 enzymatic activity, include R172K, R172S, R172T, R172G, and R172M. We present a case of SNUC with a never-before-described IDH2 mutation, R172A. Our report compares the methylation pattern of our sample to other cases from the Gene Expression Omnibus database. Hierarchical clustering suggests a strong association between our sample and other IDH-mutant SNUCs and a clear distinction between sinonasal normal tissues and tumors. Principal component analysis (PCA), using 100 principal components explaining 94.5% of the variance, showed the position of our sample to be within 1.02 standard deviation of the other IDH-mutant SNUCs. A molecular modeling analysis of the IDH2 R172A versus other R172 variants provides a structural explanation to how they affect the protein active site. Our findings thus suggest that the R172A mutation in IDH2 confers a gain of function similar to other R172 mutations in IDH2, resulting in a similar hypermethylated profile.
