    背景:膀胱癌(BC)患者根治性膀胱前列腺切除术(RCP)后,偶发前列腺癌(IPC)对肿瘤预后的影响仍存在争议。这种关系在亚洲国家还没有得到很好的阐明,前列腺癌的发病率最近急剧增加。
    目的:本研究回顾性比较了RCP标本中伴IPC和不伴IPC的BC患者的病理特征和肿瘤结局。
    方法:本研究包括142例接受BCRCP治疗的男性。先前被诊断为前列腺癌的男性被排除在外。将每个前列腺和精囊作为整体进行处理,并进行4毫米近距离切片。一名泌尿生殖系统病理学家诊断为IPC。病理特征和肿瘤结果,如总生存期(OS),膀胱癌特异性生存率(BCSS),比较IPC患者的无进展生存期(PFS)(IPC+组,n=45)且无IPC(IPC-组,n=97)。P值小于0.05被认为表明患者特征有统计学意义。由于多主要端点,P值小于0.0167被认为是肿瘤学结果的统计学意义。
    结果:我们在45个RCP样本中检测到IPC(31.6%)。IPC-组患者在手术时明显小于IPC+组(P<0.001)。RCP标本的病理特点无明显差别。在多变量分析中,IPC的存在与OS恶化显著相关(P=0.005),但没有BCSS或PFS(分别为P=0.038和0.326)。在Kaplan-Meier分析中,IPC组的OS倾向于长于IPC+组(NRvs65个月,P=0.0017)。
    结论:我们的结果表明,没有IPC的患者的OS明显优于IPC的患者。
    BACKGROUND: The impact of incidental prostate cancer (IPC) on oncological outcomes after radical cystoprostatectomy (RCP) specimens from patients with bladder cancer (BC) remains controversial. This relationship has not been well elucidated in Asian countries, where the incidence of prostate cancer has recently shown dramatic increases.
    OBJECTIVE: This study retrospectively compared pathological features and oncological outcomes between BC patients with and without IPC in the RCP specimens.
    METHODS: This study included 142 men who underwent RCP for BC. Men who were previously diagnosed with prostate cancer were excluded. Each prostate gland and seminal vesicle was processed as whole mounts and 4-mm close-step sectioning was performed. A single genitourinary pathologist diagnosed IPC. The pathological features and oncological outcomes such as overall survival (OS), bladder cancer-specific survival (BCSS), and progression-free survival (PFS) were compared between patients with IPC (IPC+group, n = 45) and without IPC (IPC- group, n = 97). P values less than 0.05 considered to indicate statistical significance for patients\' characteristics. Because of multi-primary endpoint, P values less than 0.0167 was considered statistical significance for oncological outcomes.
    RESULTS: We detected IPC in 45 RCP specimens (31.6%). Patients in the IPC- group were significantly younger at surgery than those in the IPC+group (P < 0.001). The pathological features of the RCP specimens did not differ significantly. In multivariable analyses, presence of IPC was significantly associated with worse OS (P = 0.005), but not with either BCSS or PFS (P = 0.038 and 0.326, respectively). In Kaplan-Meier analyses, OS tended to be longer in the IPC- group than that in the IPC+group (NR vs 65 months, P = 0.0017).
    CONCLUSIONS: Our results suggested significantly better OS in patients without IPC than that in those with IPC.

    一名45岁的女性出现右髋部疼痛一个月。影像学结果显示,左侧腹膜肿块伴有右侧坐骨神经支转移,肺,和腹膜后淋巴结.对左腹膜肿块进行活检。病理形态学表现为透明细胞腺癌。免疫组织化学染色显示keratin7和PAX8的阳性表达和keratin20,GCDFP-15,ER的阴性表达。PR,WT1,CDX2,绒毛,TTF-1,napsin-A,波形蛋白,calretinin,GATA3最后,诊断为原发性腹膜后苗勒氏腺癌(PRMA).PRMA是一种非常罕见的原发性腹膜后肿瘤。腹膜后肿块应考虑PRMA。
    A 45-year-old woman presented with right hip pain for a month. Imaging results revealed that the left peritoneal mass was accompanied by metastases of the right sciatic branch, lung, and retroperitoneal lymph nodes. A biopsy of the left peritoneal mass was performed. The pathological morphology demonstrated clear cell adenocarcinoma. Immunohistochemical staining revealed a positive expression of keratin7 and PAX8 and a negative expression of keratin20, GCDFP-15, ER, PR, WT1, CDX2, villin, TTF-1, napsin-A, vimentin, calretinin, and GATA3. Finally, the diagnosis of primary retroperitoneal müllerian adenocarcinoma (PRMA) was confirmed. PRMA is a very rare type of primary retroperitoneal tumor. PRMA should be considered for the retroperitoneal mass.

    在印度尼西亚,与西方人群相比,年龄<50岁的患者的早发性结直肠癌(EOCRC)发病率更高,可能是由于CRC患者中Lynch综合征(LS)的发生率较高。我们旨在检查KRAS和PIK3CA突变与LS的关联。
    在这项回顾性横断面单中心研究中,基于PCR-HRM的测试用于筛选微卫星不稳定性(MSI)单核苷酸标记(BAT25,BAT26,BCAT25,MYB,EWSR1),MLH1启动子甲基化,和BRAF(V600E)的癌基因突变,KRAS(外显子2和3),和FFPEDNA样品中的PIK3CA(外显子9和20)。
    所有样本(n=244)均来自日惹Sardjito总医院,印度尼西亚。在151/244(61.88%)和107/244(43.85%)的样本中发现KRAS和PIK3CA突变,分别。在32/42(76.19%)和25/42(59.52%)的样本中,KRAS和PIK3CA突变与MSI状态显著相关,分别。在26/32(81.25%)的样本中,KRAS突变与LS状态显著相关。PIK3CA突变在19/32(59.38%)的LS样本中存在较高比例,但没有统计学意义。临床病理显示,在39/151(25.83%)和24/151(16.44%)样本中,KRAS突变与右侧CRC和较高的组织学分级显著相关。分别。在62/107(57.94%)和26/107(30.23%)样本中,PIK3CA突变与女性和较低水平的肿瘤浸润淋巴细胞显著相关,分别。KRAS和PIK3CA突变对LS和非LS患者的总生存期(120个月)没有显著影响。
    印度尼西亚CRC患者中LS的高概率与KRAS和PIK3CA突变有关。
    UNASSIGNED: In Indonesia, early-onset colorectal cancer (EOCRC) rates are higher in patients < 50 years old compared to Western populations, possibly due to a higher frequency of Lynch syndrome (LS) in CRC patients. We aimed to examine the association of KRAS and PIK3CA mutations with LS.
    UNASSIGNED: In this retrospective cross-sectional single-center study, the PCR-HRM-based test was used for screening of microsatellite instability (MSI) mononucleotide markers (BAT25, BAT26, BCAT25, MYB, EWSR1), MLH1 promoter methylation, and oncogene mutations of BRAF (V600E), KRAS (exon 2 and 3), and PIK3CA (exon 9 and 20) in FFPE DNA samples.
    UNASSIGNED: All the samples (n = 244) were from Dr. Sardjito General Hospital Yogyakarta, Indonesia. KRAS and PIK3CA mutations were found in 151/244 (61.88%) and 107/244 (43.85%) of samples, respectively. KRAS and PIK3CA mutations were significantly associated with MSI status in 32/42 (76.19%) and 25/42 (59.52%) of samples, respectively. KRAS mutation was significantly associated with LS status in 26/32 (81.25%) of samples. The PIK3CA mutation was present in a higher proportion in LS samples of 19/32 (59.38%), but not statistically significant. Clinicopathology showed that KRAS mutation was significantly associated with right-sided CRC and higher histology grade in 39/151 (25.83%) and 24/151 (16.44%) samples, respectively. PIK3CA mutation was significantly associated with female sex and lower levels of tumor-infiltrating lymphocytes in 62/107 (57.94%) and 26/107 (30.23%) samples, respectively. KRAS and PIK3CA mutations did not significantly affect overall survival (120 months) in LS and non-LS patients.
    UNASSIGNED: The high probability of LS in Indonesian CRC patients is associated with KRAS and PIK3CA mutations.

    背景:CFAP65(纤毛和鞭毛相关蛋白65)是纤毛鞭毛发育和形成中的基本蛋白,但是很少有研究关注它在癌症中的作用。本研究旨在探讨CFAP65在结肠癌中的预后意义。
    方法:通过基因本体论(GO)数据库分析了与CFAP65相关的功能富集基因。随后,通过逆转录和定量聚合酶链反应(RT-qPCR)和免疫印迹在20对冷冻样品中评估了结肠癌中CFAP65的表达水平,包括肿瘤及其匹配的副瘤组织。此外,通过免疫组织化学染色评估189例结肠癌患者的CFAP65蛋白表达。统计学分析CFAP65表达与临床特征及长期生存的相关性。
    结果:CFAP65相关基因在细胞运动的细胞过程中显著富集,离子通道,和GTPase相关信号。CFAP65在结肠癌组织中的表达明显高于癌旁组织。CFAP65在结肠癌临床标本中高表达和低表达的比例分离为61.9%和38.1%,分别,其表达水平与包括性别在内的临床参数无关,年龄,肿瘤位置,组织学分化,肿瘤分期,血管侵犯和错配修复缺陷。CFAP65低表达肿瘤患者的5年无病生存率明显低于高表达肿瘤患者(56.9%vs.72.6%,P=0.03),但总体生存率无显著差异(69%vs.78.6%,P=0.171)。Cox风险回归分析模型显示,CFAP65表达,肿瘤分期和肿瘤部位是影响预后的独立因素。
    结论:结论:我们证明CFAP65是结肠癌肿瘤进展的潜在预测标志物.
    BACKGROUND: CFAP65 (cilia and flagella associated protein 65) is a fundamental protein in the development and formation of ciliated flagella, but few studies have focused on its role in cancer. This study aimed to investigate the prognostic significance of CFAP65 in colon cancer.
    METHODS: The functionally enriched genes related to CFAP65 were analyzed through the Gene Ontology (GO) database. Subsequently, CFAP65 expression levels in colon cancer were evaluated by reverse transcription and quantitative polymerase chain reaction (RT-qPCR) and immunoblotting in 20 pairs of frozen samples, including tumors and their matched paratumor tissue. Furthermore, protein expression of CFAP65 in 189 colon cancer patients were assessed via immunohistochemical staining. The correlations between CFAP65 expression and clinical features as well as long-term survival were statistically analyzed.
    RESULTS: CFAP65-related genes are significantly enriched on cellular processes of cell motility, ion channels, and GTPase-associated signaling. The expression of CFAP65 was significantly higher in colon cancer tissue compared to paratumor tissue. The proportion of high expression and low expression of CFAP65 in the clinical samples of colon cancer were 61.9% and 38.1%, respectively, and its expression level was not associated with the clinical parameters including gender, age, tumor location, histological differentiation, tumor stage, vascular invasion and mismatch repair deficiency. The five-year disease-free survival rate of the patients with CFAP65 low expression tumors was significantly lower than that those with high expression tumors (56.9% vs. 72.6%, P = 0.03), but the overall survival rate has no significant difference (69% vs. 78.6%, P = 0.171). The cox hazard regression analysis model showed that CFAP65 expression, tumor stage and tumor location were independent prognostic factors.
    CONCLUSIONS: In conclusion, we demonstrate CFAP65 is a potential predictive marker for tumor progression in colon cancer.

    炎性肌纤维母细胞瘤(IMT)是具有中等恶性潜能的间充质肿瘤。胃IMT很少见,通常会影响年轻人。它们通常与胃肠道间质瘤混淆,炎性纤维息肉,和平滑肌肉瘤.IMT的病因仍不清楚,但理论上是由于对慢性感染的高炎症反应。我们介绍了一名中年妇女,发现胃部幽门螺杆菌呈阳性,接受了内窥镜超声检查,只有在部分胃切除术后才明确诊断胃IMT,CD-117,S-100,ALK-1免疫组织化学阴性,波形蛋白和SMA阳性。
    Inflammatory myofibroblastic tumors (IMTs) are mesenchymal tumors of intermediate malignant potential. Gastric IMTs are rare and commonly affect young adults. They are typically confused with gastrointestinal stromal tumors, inflammatory fibroid polyps, and leiomyosarcomas. The etiology of IMTs remains unclear, but is theorized to be due to hyperinflammatory response to chronic infections. We present a middle-aged woman found to have a gastric mass positive for Helicobacter pylori, underwent multiple endoscopies with endoscopic ultrasound, and a definitive diagnosis of gastric IMT was only made after a partial gastrectomy with immunohistochemistry negative for CD-117, S-100, ALK-1, and positive for vimentin and SMA.

    春季角膜结膜炎(VKC)是一种慢性,进步,过敏性眼表疾病,可导致危及视力的并发症。VKC主要发生在儿童中,通常在青春期左右解决;然而,病例系列和回顾性分析表明,大约10%的VKC患者是成年人,一部分成人病例在青春期后发展。因此,最近描述了两种与年龄相关的VKC变体:早发性VKC-在儿童期表现并持续到成人生活和迟发性疾病,这是青春期后从头出现的。虽然成人和儿童VKC的症状和体征相似,成人VKC是一种长期的疾病,其特征是严重的炎症和结膜纤维化的风险增加,这可能会使成年患者面临更高的危及视力的并发症和对日常生活的不利影响的风险。这篇综述讨论了流行病学,标志,症状,成人VKC变体的免疫发病机制,并强调了目前在这种情况下患者的研究和管理方面的差距。
    Vernal keratoconjunctivitis (VKC) is a chronic, progressive, allergic ocular surface disorder that can lead to sight-threatening complications. VKC occurs primarily in children and generally resolves about the time of puberty; however, case series and retrospective analyses indicate that approximately 10% of patients with VKC are adults, and that a subset of adult cases develop after puberty. Consequently, two age-related variants of VKC have recently been described: early-onset VKC-which manifests during childhood and persists into adult life-and late-onset disease, which emerges de novo after puberty. Although the signs and symptoms of adult and childhood VKC are similar, adult VKC is a long-lasting disease characterized by severe inflammation and increased risk of conjunctival fibrosis, which may place adult patients at higher risk for sight-threatening complications and adverse impacts on daily life. This review discusses the epidemiology, signs, symptoms, immunopathogenesis of adult VKC variants, and highlights current gaps in research and management of patients with this condition.

    医学文献显示,缺乏关于医学实习生和住院医师对本科课程期间提供给他们的课程的意见的信息,无论是在一组独立的主题中,还是在一个整合和有效的主题中(即,病理学)。
    评估和比较实习生和居民对病理学的看法。在临床实践中认识到他们对病理学的相关性和应用的看法。
    这项研究是一项横向在线研究,针对实习生和居民的自我管理问卷。问卷由30个问题组成,询问人口统计数据,主体力量,教学持续时间,对主题的兴趣,以及病理学在临床实践中作为学科的有用性。
    总的来说,103名参与者完成了调查。女性和男性的百分比分别为59.2%和40.8%。86.4%的参与者是实习生,居民占13.6%。87%的参与者同意在临床实践中应用病理学是一项技能,应在医学临床前教育的早期阶段予以加强。适度的百分比认为从业者可以有效地治疗大多数患者,而无需了解所涉及的病理机制的细节。大多数参与者认为病理学课程有助于他们进行鉴别诊断,分析正常和病理成分,以及结构的解剖和鉴定。
    这项研究强调了约旦实习生和居民对病理学课程的积极看法。它还表明,参与者更喜欢积极和动态的教育模式,重点是更好地整合病理课程和临床经验,以满足他们在临床实践中的需求。因此,我们建议在未来的研究中,将参加课程的实习生和住院医师的能力与综合医学课程进行比较,病理学与研究病理学传统医学课程的人相比,以及评估他们对医学教育的看法。
    UNASSIGNED: Medical literature revealed that there is a lack of information about the opinions of medical interns and residents about curricula provided to them during their undergraduate programs, either in a group of detached subjects or an incorporated and efficacious topic (ie, pathology).
    UNASSIGNED: To assess and compare the interns\' and residents\' perspectives towards Pathology as a subject. To recognize their opinions toward the relevance and application of Pathology while practicing clinically.
    UNASSIGNED: This study was a cross-sectional online, self-administered questionnaire targeting interns and residents. The questionnaire consisted of 30 questions, enquiring about the demographic data, subject strength, teaching duration, interest in the subject, and usefulness of Pathology as a subject in clinical practice.
    UNASSIGNED: Overall, 103 participants completed the survey. The female and male percentage was 59.2% and 40.8% respectively. 86.4% of participants were interns, while 13.6% were residents. 87% of participants agreed that applying pathology during clinical practice is a skill that should be strengthened in the early stages of preclinical education of Medicine. A modest percentage believed that a practitioner could efficiently treat the majority of patients with no need to know the specifics of the pathological mechanisms involved. Most of the participants believed that pathology courses helped them in making a differential diagnosis, analysis of normal and pathological constituents, and dissection and identification of structures.
    UNASSIGNED: This study highlights the positive perceptions of Jordanian interns and residents toward pathology courses. It also demonstrates that participants prefer an active and dynamic educational model with an emphasis on better integration of pathology courses and clinical experiences that fit their needs in clinical practice. Thus, we recommend future studies to compare the competencies of interns and residents enrolled in the courses with integrated medical curricula, of pathology versus those who studied the conventional medical curricula of pathology, as well as to evaluate their perceptions of medical education.
