    背景:正常的癌前倾向,胰腺未受影响的部分没有像胰腺癌病例中记录的多中心那样得到很好的探索。为了确定炎症标志物和红细胞癌基因B(ErbB2)在胰腺癌患者未受影响的胰腺中的表达,进行了一项病例对照研究.材料和方法在接受胰十二指肠切除术治疗胰腺癌(PC)的患者中,促炎基因和肿瘤标志物,使用qRT-PCR在正常胰腺切面的胰腺组织中分析了表皮生长因子受体家族中的红细胞癌基因2(ErbB2)。选择20例Frey手术后诊断为慢性胰腺炎(CP)的患者,和他们的胰腺组织作为对照进行分析。使用国家生物技术信息中心(NCBI)软件设计HPLC纯化的引物。使用基本局部比对搜索工具(BLAST)验证引物的特异性用于基因表达分析。使用β-肌动蛋白作为管家基因对研究中的基因进行归一化,并使用2-ddct方法计算与对照样品相比的倍数变化。结果未纳入切缘阳性患者。促炎基因(TNF-α,NF-kβ,与CP组相比,PC患者中COX-2)的折叠变化显着降低。CP对照组的IL-6基因表达水平高于PC组。胰腺癌患者的ErbB2基因表达明显高于CP患者。结论胰腺癌患者胰腺组织中ErbB2基因表达上调,与对照组相比,表明剩余的胰腺可能具有导致癌症的能力。原癌基因可能在胰腺癌患者的病理生理过程中起作用。
    Background The pre-malignant tendency of the normal, non-affected portion of the pancreas is not as well explored as the multicentricity documented in pancreatic cancer cases. In order to ascertain the expression of inflammatory markers and Erythroblastic Oncogene B (ErbB2) in the non-affected pancreas in patients with pancreatic cancer, a case-control study was carried out. Materials and methods In patients who underwent pancreatoduodenectomy for pancreatic cancer (PC), pro-inflammatory genes and a tumor marker, erythroblastic oncogene 2 (ErbB2) in the epidermal growth factor receptor family were analyzed in the pancreatic tissue at the cut surface of the normal pancreas using qRT-PCR. Twenty patients diagnosed with Chronic pancreatitis (CP) after Frey\'s surgical procedure were selected, and their pancreatic tissues were analyzed as controls. The HPLC-purified primers were designed using National Center for Biotechnology Information (NCBI) software. The primer\'s specificity was verified for gene expression analysis using the Basic Local Alignment Search Tool (BLAST). The genes under study were normalized using β-actin as the housekeeping gene, and the 2-ddct method was used to compute the fold change compared to the control sample. Results Patients with margin-positive were not included. Pro-inflammatory genes (TNF-α, NF-kβ, and COX-2) had significantly lower foldchange in PC patients compared to the CP group. The CP control group had higher levels of IL-6 gene expression than the PC group. Patients with pancreatic cancer had a considerably higher expression of the ErbB2 gene than patients with CP. Conclusion The upregulated ErbB2 gene in the unaffected pancreatic tissue of pancreatic cancer patients, when compared to controls, indicates that the remaining pancreas may have the capacity to cause cancer. Proto-oncogene may play a role in the pathophysiologic process in patients with pancreatic cancer.

    Schnitzler的转移是由于肿瘤细胞在直肠粘膜下层的沉积而发生的,导致直肠狭窄.我们介绍了一位60岁的女性,她出现了腹痛,扩张,和呕吐。腹部检查显示腹部扩张和明显的肠loop,经直肠检查显示直肠狭窄。影像学检查提示直肠狭窄伴胰头癌。该患者被诊断为Schnitzler转移伴胰头癌,这在文献中没有报道过。该患者接受了乙状结肠分流术,并计划在胆总管支架置入后进行姑息性化疗。
    Schnitzler\'s metastasis occurs due to the deposition of the tumor cells in the submucosa of the rectum, leading to rectal stenosis. We present a 60-year-old female who presented with abdominal pain, distension, and vomiting. Abdominal examination showed a distended abdomen and palpable bowel loops, and per rectal examination showed rectal stenosis. Imaging studies suggest rectal stenosis with carcinoma of the pancreas head. The patient was diagnosed with Schnitzler\'s metastasis with carcinoma of the pancreas head, which has not been reported in the literature. The patient underwent a diversion sigmoid colostomy and was planned for palliative chemotherapy after stenting the common bile duct.

    简介胰十二指肠切除术(PD)的执行方式在世界各地可能有很大差异,也没有商定的标准方法。要了解更多关于PD在印度的实践,在印度外科医生中进行了一项调查,以收集有关他们当前实践的信息。方法创建了一项调查,并与从事胰腺手术的印度外科医生共享。它有33个问题,旨在获取有关PD实践不同方面的信息。这些问题涵盖了诸如外科医生的教育和经验等主题,他们在手术前如何评估病人,他们在手术中考虑的是什么,以及他们在手术后如何管理病人。结果共有129名外科医生接受调查,110人完成了。结果显示,40.9%的外科医生经验不足五年,其中36.4%的人一年内完成了15次以上的PD。在决定是否进行术前胆道引流时,60%的外科医生根据患者血液中的胆红素水平做出决定,而其余的则考虑了其他具体的适应症。大多数外科医生(72.7%)在手术前观察白蛋白水平的趋势以评估患者的营养状况。76.4%的参与者将静脉浸润视为新辅助治疗的原因。而95.5%的人在静脉基台的情况下考虑了前期手术。当涉及到PD的类型时,40%首选经典PD,40.9%首选幽门切除PD(PRPD),其余选择保留幽门的PD(PPPD)。胰肠造口术(PJ)是77.3%外科医生的首选方法,而6.3%的人首选胰胃吻合术(PG)。当导管直径较小时,约65.5%的外科医生在手术中选择性使用奥曲肽。几乎所有外科医生(94.5%)都倾向于在PD期间确保进食通道。他们都放置了腹膜内的排水沟。至于术后护理,37.3%的外科医生在48小时内尝试早期经口进食,而28.2%的人更愿意在开始口服前等待至少48小时。结论调查显示,印度外科医生之间的PD练习方式存在显着差异,强调他们的方法和偏好的异质性。
    Introduction The way pancreatoduodenectomy (PD) is performed can vary a lot around the world, and there is no agreed-upon standard approach. To learn more about how PD is practised in India, a survey was conducted among Indian surgeons to gather information about their current practices. Methods A survey was created and shared with surgeons in India who practice pancreatic surgery. It had 33 questions that aimed to capture information about different aspects of PD practice. These questions covered topics such as the surgeons\' education and experience, how they evaluated patients before surgery, what they considered during the operation, and how they managed patients after surgery. Results A total of 129 surgeons were sent the survey, and 110 of them completed it. The results showed that 40.9% of the surgeons had less than five years of experience, and 36.4% of them performed more than 15 PDs in a year. When deciding whether to perform preoperative biliary drainage, 60% of surgeons based their decision on the level of bilirubin in the patient\'s blood, while the rest considered other specific indications. The majority of surgeons (72.7%) looked at the trend of albumin levels to assess the patient\'s nutritional status before surgery. Venous infiltration was seen as a reason for neoadjuvant therapy by 76.4% of the participants, whereas 95.5% considered upfront surgery in cases of venous abutment. When it came to the type of PD, 40% preferred classical PD, 40.9% preferred pylorus-resecting PD (PRPD), and the rest chose pylorus-preserving PD (PPPD). Pancreatojejunostomy (PJ) was the preferred method for 77.3% of surgeons, while 6.3% preferred pancreatogastrostomy (PG). About 65.5% of surgeons used octreotide selectively during the operation when the duct diameter was small. Nearly all surgeons (94.5%) preferred to secure feeding access during PD, and all of them placed intraperitoneal drains. As for postoperative care, 37.3% of surgeons attempted early oral feeding within 48 hours, while 28.2% preferred to wait at least 48 hours before initiating oral feeds. Conclusions The survey revealed significant differences in how PD is practised among surgeons in India, highlighting the heterogeneity in their approaches and preferences.

    虽然大约85%的肿瘤是导管胰腺腺癌(DPA),腺鳞状胰腺癌(APC)是一种罕见的胰腺癌亚型,表现出侵袭行为和不良预后。作者报告了使用新型ProCore20G针通过内窥镜超声引导的组织采集(EUS-TA)诊断出的三例原发性APC,通过为组织病理学提供更多组织来改善细针抽吸结果。鉴于它的微核检索能力,胰腺间质检查,和出色的组织病理学结果,EUS-TA在胰腺实性病变患者中表现出出色的诊断率。本文提出的所有三个APC病例都在微核采集后使用免疫组织化学进行了准确诊断。
    While approximately 85% of neoplasms are ductal pancreatic adenocarcinomas (DPA), adenosquamous pancreatic carcinoma (APC) is a rare subtype of pancreatic cancer that exhibits aggressive behavior and poor prognosis. The authors report three cases of primary APC diagnosed through endoscopic ultrasound-guided tissue acquisition (EUS-TA) using the new ProCore 20G needle, which had been developed to improve fine-needle aspiration results by providing more tissue for histopathology. Given its ability for microcore retrieval, pancreatic stroma examination, and excellent histopathology results, EUS-TA has exhibited exceptional diagnostic yield among patients with solid pancreatic lesions. All three APC cases presented herein had been accurately diagnosed using immunohistochemistry after microcore acquisition.

    多年来,世界在诊断和治疗多种癌症方面取得了许多进展。这些突破彻底改变了对这些肿瘤背后分子驱动的理解,导致切实的治疗进展和有希望的预后影响。然而,胰腺癌仍然是一种高度致命的疾病。根据最近的发现,现代医学已经能够描述胰腺癌的组织病理学亚型,以期改善诊断和治疗以提高生存率。一个曾经模糊的实体,胰腺透明细胞腺癌,特别是,在过去的二十年中,在组织病理学和分子水平上得到了更好的表征。有了新颖的技术支持,这种疾病变得不那么显眼了,更多的研究人员报道了它的发生。它的诊断在很大程度上依赖于组织学和免疫组织化学线索的混合,例如清晰的细胞质和细胞角蛋白和其他标志物的阳性。然而,新的分子标记,如肝细胞核因子1β,已与该实体相关,并可能有助于进一步的诊断和治疗策略。这篇综述文章旨在描述胰腺透明细胞腺癌的识别和描述在过去几十年中如何演变,以及这可能如何影响未来的治疗策略。
    Over the years, the world has witnessed many advances in diagnosing and treating multiple types of cancers. These breakthroughs have revolutionized the understanding of the molecular drive behind these neoplasms, leading to tangible therapeutic evolution and promising prognostic implications. However, pancreatic cancer remains a highly lethal disease. With recent discoveries, modern medicine has been able to delineate histopathologic subtypes of pancreatic cancer in hopes of improved diagnosis and treatment to improve survival. A once vague entity, clear cell adenocarcinoma of the pancreas, in particular, has been better characterized on a histopathological and molecular level over the past two decades. With novel technological support, this disease has become less inconspicuous, and more researchers have reported its occurrence. Its diagnosis relies heavily on a mix of histological and immunohistochemical clues such as a clear cell cytoplasm and positivity for cytokeratins and other markers. However, new molecular markers, such as hepatocyte nuclear factor 1 beta, have been associated with this entity and may aid in further diagnostic and therapeutic strategies. This review article aims to portray how the identification and description of clear cell adenocarcinoma of the pancreas have evolved over the past few decades and how this may impact future treatment strategies.

    具有破骨细胞样巨细胞的未分化胰腺癌(UPC-OGC)是一种独特且罕见的肿瘤,其特征是存在高度非典型的癌细胞和非肿瘤性破骨细胞样巨细胞。该肿瘤的组织起源尚不清楚,其预后数据仍存在争议。一些数据显示受影响患者的临床结果较差,而其他最近的研究报告了更好的结果,尤其是对于纯UPC-OGC的病例。目前尚无针对UPC-OGC的可靠管理指南,部分原因是其稀有性和文献中存在相互矛盾的数据。因此,需要继续报告和进一步研究这种肿瘤。我们报告了一名患有尿路感染(UTI)症状的老年男性患者中UPC-OGC的偶然发现,并伴有导管腺癌和局灶性印戒特征。
    Undifferentiated pancreatic carcinoma with osteoclast-like giant cells (UPC-OGC) is a unique and rare tumor characterized by the presence of highly atypical carcinoma cells and non-neoplastic osteoclast-like giant cells. The histogenesis of this tumor is unclear and data on its prognosis remain controversial. Some data show poor clinical outcomes in affected patients while other more recent studies report a better outcome especially for cases with pure UPC-OGC. There are currently no established reliable management guidelines for UPC-OGC partly because of its rarity and presence of conflicting data in the literature. Hence the need for continued reporting and further research on this neoplasm. We report an incidental finding of UPC-OGC with associated ductal adenocarcinoma and focal signet ring features in an elderly male patient who presented with symptoms of urinary tract infection (UTI).

    沟槽性胰腺炎是一种罕见的慢性胰腺炎,影响十二指肠第二部分附近的沟槽区域。临床和生化特征通常与慢性胰腺炎的其他亚组重叠,而影像学特征类似于胰头癌。我们介绍了一名38岁的腹痛男子,恶心,呕吐,接受18F-FDGPET/CT检查以排除胰腺恶性肿瘤的体重减轻。沟槽型胰腺炎的PET/CT影像特征有别于其他慢性胰腺炎,如酒精性和自身免疫性胰腺炎,并有助于患者的诊断和计划进一步管理。
    Groove pancreatitis is a rare form of chronic pancreatitis that affects the groove area adjacent to the second part of the duodenum. Clinical and biochemical features often overlap with other subsets of chronic pancreatitis, while the imaging features resemble that of carcinoma of the head of pancreas. We present a 38-year-old man with abdominal pain, nausea, vomiting, and loss of weight who underwent 18F-FDG PET/CT to rule out a pancreatic malignancy. PET/CT imaging features of groove pancreatitis are distinct from the other subsets of chronic pancreatitis, such as alcoholic and autoimmune pancreatitis, and helpful in the diagnosis and planning further management of the patient.

    内镜超声(EUS)已成为胰腺癌诊断和治疗的重要组成部分。随着先进的成像技术和组织采集方法的出现,EUS的作用变得越来越重要。小胰腺肿瘤可以可靠地诊断为EUS。在某些情况下,EUS引导的细针抽吸可以诊断。EUS在胰腺癌的分期和一些重要的治疗方法中起重要作用,包括腹腔神经丛神经溶解,EUS引导胆道引流和给药。在这篇综述中,我们试图回顾EUS在胰腺癌的诊断和治疗中的作用。
    Endoscopic ultrasound (EUS) has become an important component in the diagnosis and treatment of carcinoma pancreas. With the advent of advanced imaging techniques and tissue acquisition methods the role of EUS is becoming increasingly important. Small pancreatic tumors can be reliably diagnosed with EUS. EUS guided fine needle aspiration establishes diagnosis in some cases. EUS plays an important role in staging of carcinoma pancreas and in some important therapeutic methods that include celiac plexus neurolysis, EUS guided biliary drainage and drug delivery. In this review we attempt to review the role of EUS in diagnosis and management of carcinoma pancreas.
