    继发于肿块效应的下腔静脉(IVC)压迫伴有水肿,腹水,背部和腹部疼痛,和中枢神经系统症状。文献中描述的大多数IVC综合征病例集中于IVC病变的局灶性治疗,在姑息治疗的情况下,继发于恶性IVC综合征的完整髂静脉重建的报道有限。在这个案例报告中,我们描述了临床表现,技术方法,以及患有广泛恶性压迫和侵袭髂股静脉系统的患者的症状结果。一名82岁男性转移性肺癌侵犯右上腹,表现为阴囊和双侧下肢水肿,还有Anasarca.计算机断层扫描(CT)显示11厘米的右肾上腺转移和广泛的腹膜后淋巴结肿大,导致IVC和the静脉受压。股静脉造影显示广泛的侧支静脉途径形成,腰椎旁静脉和椎静脉混浊,除了椎/骶静脉丛。使用静脉专用支架进行Iliocal重建。此病例报告强调了在弥漫性转移性疾病导致IVC压迫和综合征的复杂姑息性患者中技术上成功的全静脉重建。
    Inferior vena cava (IVC) compression secondary to mass effect is accompanied by edema, ascites, back and abdominal pain, and central nervous system symptoms. Most IVC syndrome cases described in the literature focus on the focal treatment of IVC lesions, and reports of complete iliocaval reconstructions secondary to malignant IVC syndrome in the palliative context are limited. In this case report, we describe the clinical presentation, technical approach, and symptomatic outcomes of a patient with extensive malignant compression and invasion of the iliofemoral venous system. An 82-year-old male with metastatic lung cancer invading the right upper quadrant of the abdomen presented with scrotal and bilateral lower extremity edema, as well as anasarca. Computed tomography (CT) demonstrated an 11 cm right adrenal metastasis and extensive retroperitoneal lymphadenopathy resulting in the compression of the IVC and iliac veins. Femoral venography demonstrated extensive collateral venous pathway formation with the opacification of the para-lumbar and vertebral veins, in addition to the vertebral/sacral venous plexus. Iliocaval reconstruction was performed using venous-dedicated stents. This case report highlights a technically successful total iliocaval reconstruction in a complex palliative patient with diffuse metastatic disease resulting in IVC compression and syndrome.

    小口径中心静脉导管的股腹部隧穿是一种床边技术,适用于有禁忌症的患者胸腔入路,或作为下肢导管出口部位的替代方案。
    对接受有胸静脉入路禁忌症或下肢导管出口部位的中长期静脉内治疗的患者实施了股骨至腹部隧道技术。在局部麻醉下在超声引导下插入所有静脉接入装置。和导管尖端放置通过术后射线照相术评估。
    在这种情况下,从2020年1月到2023年1月,总共插入了8个FTA隧道式静脉接入设备。有七名卧床病人和一名卧床病人。皮下隧道的中位长度为20厘米,范围从15到27厘米。静脉导管至末梢的中位长度为31厘米,范围从23到40厘米。术后腹部X线片确认尖端位置。导管尖端位置被解释为在T8-T9(2)水平,T12(1),L4(2),L2(2),L1(1).未报告插入或插入后相关并发症。六名患者完成了预定的静脉治疗。一名患者由于转移到外部设施而无法追踪。最初证明在左髂总血管上盘绕的一根导管使用高流量冲洗技术重新定位。据报道,提供护理和维护的护士有导管移位。总体植入天数为961天,中位停留时间为125天,范围为20至399天。
    股骨至腹部隧道术提供了一种替代的出口部位,可用于选择具有复杂静脉通路的患者。这项小型回顾性研究的数据表明,这是一种安全且微创的床边手术。
    UNASSIGNED: Femoral to abdomen tunneling of small-bore central venous catheters is a bedside technique for patients with contraindications to a thoracic approach, or as an alternative to a lower extremity catheter exit site.
    UNASSIGNED: A femoral to abdomen tunneling technique was implemented for patients receiving medium and long-term intravenous treatments with contraindications to the thoracic venous approach or as an alternative to a lower extremity catheter exit site. All venous access devices were inserted with ultrasound guidance under local anesthesia, and catheter tip placement assessed by post procedural radiography.
    UNASSIGNED: In this case series, from January 2020 to January 2023, a total of eight FTA-tunneled venous access devices were inserted. There were seven ambulatory patients and one bedbound patient. The median length of the subcutaneous tunnel was 20 cm, ranging from 15 to 27 cm. The median length of the intravenous catheter to the terminal tip was 31 cm, ranging from 23 to 40 cm. Tip location was confirmed by post-procedural abdominal radiograph. The catheter tip locations were interpreted to be at the level of T8-T9 (2), T12 (1), L4 (2), L2 (2), L1(1).No insertion or post insertion related complication was reported. Six patients completed the scheduled intravenous treatment. One patient was unable to be tracked due to transfer to an outside facility. One catheter initially demonstrated to be coiled over the left common iliac vessel was repositioned using a high flow flush technique. There was one reported catheter dislodgment by the nurse providing care and maintenance. The overall implant days were 961, with a median dwell time of 125 days ranging from 20 to 399 days.
    UNASSIGNED: Femoral to abdomen tunneling provides an alternative exit site useful in select patients with complex intravenous access. The data of this small retrospective review suggests this a safe and minimally invasive bedside procedure.

    化疗是治疗转移性肺癌的主要方法之一。虽然受限于抗癌药物的低肿瘤递送功效。由于其高免疫刺激作用,细菌疗法正在出现用于癌症治疗;然而,过度产生的免疫原性会引起严重的炎症反应综合征。这里,我们通过逐层封装制备了肿瘤细胞膜包被的脂质体载紫杉醇细菌鬼影(LP@BG@CCM),用于治疗转移性肺癌.制备工艺简单,只涉及成膜,电穿孔,和孔隙挤压。LP@BG@CCM比LP@BG具有更高的4T1癌细胞毒性,因为它与癌细胞的融合更快。在4T1乳腺癌转移性肺癌小鼠模型中,观察到静脉内注射LP@BG@CCM的明显更高的肺靶向性,肺外观几乎恢复正常,肺重量减少,清晰的肺组织结构,与其前体相比,癌细胞凋亡增强。此外,LP@BG@CCM后几个主要免疫因子得到改善,包括脾脏中的CD4+/CD8a+T细胞和TNF-α,IFN-γ,和IL-4在肺中。LP@BG@CCM表现出最佳的协同化学免疫疗法,这是一种治疗转移性肺癌的有前途的药物。
    Chemotherapy is one of the major approaches for the treatment of metastatic lung cancer, although it is limited by the low tumor delivery efficacy of anticancer drugs. Bacterial therapy is emerging for cancer treatment due to its high immune stimulation effect; however, excessively generated immunogenicity will cause serious inflammatory response syndrome. Here, we prepared cancer cell membrane-coated liposomal paclitaxel-loaded bacterial ghosts (LP@BG@CCM) by layer-by-layer encapsulation for the treatment of metastatic lung cancer. The preparation processes were simple, only involving film formation, electroporation, and pore extrusion. LP@BG@CCM owned much higher 4T1 cancer cell toxicity than LP@BG due to its faster fusion with cancer cells. In the 4T1 breast cancer metastatic lung cancer mouse models, the remarkably higher lung targeting of intravenously injected LP@BG@CCM was observed with the almost normalized lung appearance, the reduced lung weight, the clear lung tissue structure, and the enhanced cancer cell apoptosis compared to its precursors. Moreover, several major immune factors were improved after administration of LP@BG@CCM, including the CD4+/CD8a+ T cells in the spleen and the TNF-α, IFN-γ, and IL-4 in the lung. LP@BG@CCM exhibits the optimal synergistic chemo-immunotherapy, which is a promising medication for the treatment of metastatic lung cancer.

    转移性肺癌被认为是最具临床意义的恶性肿瘤之一。约占癌症死亡人数的40%。在症状复发之前检测肺癌转移对于及时诊断和临床治疗至关重要。癌症转移的发作由外周循环中原发性肿瘤的肿瘤脱落特征的表现来指示。这个人口的一个子集,以转移起始干细胞为特征,能够入侵,肿瘤起始,和远处转移的传播。在这项研究中,我们开发了一种SERS功能化的L-MISC(肺转移起始干细胞)纳米传感器,可直接从患者血液中准确捕获痕量水平的转移特征.我们研究了富含癌症干细胞的原发性和转移性肺癌细胞的异质性群体的特征,以建立肺癌特有的转移谱。多变量统计分析显示,健康人群的分子谱存在统计学上的显著差异,小学,和转移性细胞群。L-MISC纳米传感器的单细胞灵敏度使得能够以高灵敏度和特异性对MISC进行无标记检测。通过采用鲁棒的机器学习模型,我们的诊断方法可以从不超过5μl的血液中准确检测出转移性肺癌。使用临床样品对我们的研究进行了初步验证,以预测转移性肺癌,从而产生100%的诊断敏感性。L-MISC纳米传感器是一个潜在的工具,非侵入性,并准确诊断肺癌转移。
    Metastatic lung cancers are considered one of the most clinically significant malignancies, comprising about 40% of deaths caused by cancers. Detection of lung cancer metastasis prior to symptomatic relapse is critical for timely diagnosis and clinical management. The onset of cancer metastasis is indicated by the manifestation of tumor-shed signatures from the primary tumor in peripheral circulation. A subset of this population, characterized as the metastasis-initiating stem cells, are capable of invasion, tumor initiation, and propagation of metastasis at distant sites. In this study, we have developed a SERS-functionalised L-MISC (Lung-Metastasis Initiating Stem Cells) nanosensor to accurately capture the trace levels of metastatic signatures directly from patient blood. We investigated the signatures of cancer stem cell enriched heterogenous population of primary and metastatic lung cancer cells to establish a metastatic profile unique to lung cancer. Multivariate statistical analyses revealed statistically significant differences in the molecular profiles of healthy, primary, and metastatic cell populations. The single-cell sensitivity of L-MISC nanosensor enabled a label-free detection of MISCs with high sensitivity and specificity. By employing a robust machine learning model, our diagnostic methodology can accurately detect metastatic lung cancer from not more than 5 μl of blood. A pilot validation of our study was carried out using clinical samples for the prediction of metastatic lung cancers resulting in 100% diagnostic sensitivity. The L-MISC nanosensor is a potential tool for highly rapid, non-invasive, and accurate diagnosis of lung cancer metastasis.

    尽管肺癌的治疗取得了进展,肺粘膜屏障的存在仍然阻碍了治疗剂的渗透和扩散,并极大地限制了治疗效果。在这项工作中,我们报道了一种新型的可吸入pH响应四面体DNA纳米机器,同时递送免疫调节CpG寡核苷酸和PD-L1靶向拮抗DNA适体(CP@TDN),可有效治疗肺转移癌.通过精确控制CpG和PD-L1适体的比例,获得的CP@TDN可以特异性释放PD-L1适体,阻断酸性肿瘤微环境中的PD-1/PD-L1免疫检查点轴,然后通过抗原呈递细胞内吞产生抗肿瘤免疫激活和分泌抗肿瘤细胞因子。此外,吸入递送CP@TDN显示高效的肺沉积与极大增强的肿瘤内积累,归因于DNA四面体介导的肺粘膜渗透。结果,CP@TDN可以通过诱导强烈的抗肿瘤反应显着抑制转移性原位肺癌的生长。因此,我们的工作通过生物相容性DNA四面体作为有效治疗转移性肺癌的吸入给药系统,提出了一种有吸引力的方法。
    Despite advancements in the treatment of pulmonary cancer, the existence of mucosal barriers in lung still hampered the penetration and diffusion of therapeutic agents and greatly limited the therapeutic benefits. In this work, we reported a novel inhalable pH-responsive tetrahedral DNA nanomachines with simultaneous delivery of immunomodulatory CpG oligonucleotide and PD-L1-targeting antagonistic DNA aptamer (CP@TDN) for efficient treatment of pulmonary metastatic cancer. By precisely controlling the ratios of CpG and PD-L1 aptamer, the obtained CP@TDN could specifically release PD-L1 aptamer to block PD-1/PD-L1 immune checkpoint axis in acidic tumor microenvironment, followed by endocytosis by antigen-presenting cells to generate anti-tumor immune activation and secretion of anti-tumor cytokines. Moreover, inhalation delivery of CP@TDN showed highly-efficient lung deposition with greatly enhanced intratumoral accumulation, ascribing to the DNA tetrahedron-mediated penetration of pulmonary mucosa. Resultantly, CP@TDN could significantly inhibit the growth of metastatic orthotopic lung tumors via the induction of robust antitumor responses. Therefore, our work presents an attractive approach by virtue of biocompatible DNA tetrahedron as the inhalation delivery system for effective treatment of metastatic lung cancer.

    非小细胞肺癌(NSCLC)的治疗前景在过去几年中已经有了很大的发展。靶向药物和分子诊断已经快速发展。这篇叙述性综述从发现ALK蛋白,探讨了间变性淋巴瘤激酶(ALK)靶向治疗的演变。分子测试,目前的临床试验数据和未来的观点。由于肺癌的证据每天都在增加,大多数肿瘤学家需要时间在日常实践中实施数据。
    我们进行了叙述性综述,为ALK改变的NSCLC患者的临床决策提供最新帮助。2022年,作者回顾了PubMed发表的关键随机3期试验结果。
    ALK抑制剂的开发是一场仍在进行的革命;第二代和第三代ALK抑制剂提供了超过30个月的无进展生存期(PFS)和令人印象深刻的“脑控制”。Brigatinib为基线脑转移患者提供了生存益处(HR0.43,95%CI:0.21-0.89),洛拉替尼的颅内反应率为82%,71%的颅内完全缓解.个性化医疗是新的范式,从进行广泛的遗传小组诊断到单独的靶向治疗或不同靶向药物的组合。
    在未来,进行宽分子面板应该是在前线和每次进展后检测出现的耐药机制的标准护理。在接下来的几十年中,更长的PFS将使致命的疾病转化为几乎慢性的疾病。治疗测序将是患者生存的基石,和液体活检可以代替组织活检。
    UNASSIGNED: The therapeutic landscape for non-small cell lung cancer (NSCLC) has evolved considerably in the last few years. The targeted drugs and molecular diagnostics have been developed together at a fast pace. This narrative review explores the evolution of anaplastic lymphoma kinase (ALK) targeting therapies from discovering the ALK protein, molecular tests, present clinical trial data and future perspectives. Since the body of evidence on lung cancer is growing daily, most oncologists need time to implement data in their daily practice.
    UNASSIGNED: We developed a narrative review to provide up-to-date help in the clinical decision-making of ALK-altered NSCLC patients. In 2022, the authors reviewed PubMed\'s published pivotal randomized Phase 3 trial results.
    UNASSIGNED: The development of ALK inhibitors was a revolution that is still ongoing; second and third-generation ALK inhibitors provided more than 30 months of progression-free survival (PFS) and impressive \"brain-control\". Brigatinib provided a survival benefit for patients with baseline brain metastases (HR 0.43, 95% CI: 0.21-0.89), and Lorlatinib demonstrated intracranial response rates of 82%, with 71% of complete intracranial responses. Personalized medicine is the new paradigm, from performing broad genetic panels for diagnosis to individual targeted therapy or combinations of different targeted agents.
    UNASSIGNED: In the future, performing broad molecular panels should be the standard of care in the front line and after each progression to detect arising resistance mechanisms. Longer PFS will substantially convert a deadly condition into an almost chronic disease in the following decades. Treatment sequencing will be the cornerstone for patient survival, and liquid biopsies may replace tissue biopsies.

    背景:随着IV期非小细胞肺癌患者的寿命延长,临终(EOL)护理和经验的相关性越来越重要。方法:我们,因此,前瞻性检查心理灵性之间的关联(流行病学研究中心抑郁量表,慢性病治疗的功能评估-精神幸福感),围绕着对死亡和疾病进展的恐惧的讨论,以及患者和护理人员的医院EOL护理。患者还报告了症状负担(MDAnderson症状清单-肺癌总数)和生活质量(QOL)(EOL的生活质量)。结果:在基线患者中(n=75),32%在分析时存活(平均=基线后4.6年)。死亡患者(n=51)为中年(平均65.3岁)和非西班牙裔白人(81%)。护理人员的精神幸福感(r=0.34,p=0.02)和抑郁(r=-0.31,p=0.03)与EOL护理指标相关。那些“抑制”更多的死亡或疾病进展恐惧的患者经历了更大的症状负担(r=0.41,p<0.001)和更差的生活质量(r=-0.44,p<0.001)。结论:对于面临长期转移性疾病的夫妇,心理灵性与EOL护理高度相关,可能会导致对死亡或疾病进展的恐惧。
    Background: As patients live longer with stage IV nonsmall cell lung cancer, correlates of end-of-life (EOL) care and experience are increasingly relevant. Methods: We, therefore, prospectively examined associations among psychospirituality (Center for Epidemiologic Studies Depression Scale, Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being), discussions around fear of death and disease progression, and hospital-based EOL care in patients and caregivers. Patients additionally reported symptom burden (MD Anderson Symptom Inventory-Lung Cancer total) and quality of life (QOL) (quality-of-life at EOL). Results: Of the baseline patients (n = 75), 32% were alive at time of the analyses (mean = 4.6 years postbaseline). Deceased patients (n = 51) were middle aged (mean = 65.3 years) and non-Hispanic White (81%). Caregiver spiritual well-being (r = 0.34, p = 0.02) and depression (r = -0.31, p = 0.03) were associated with EOL care metrics. Patients who \"held back\" more of their fear of death or disease progression experienced greater symptom burden (r = 0.41, p < 0.001) and poorer QOL (r = -0.44, p < 0.001). Conclusion: For couples facing prolonged metastatic disease, psychospirituality is highly relevant to EOL care with potential sequelae of withholding one\'s fear regarding death or disease progression.

    从肺癌到口腔和头部和颈部的转移通常很少发生,并且通常在疾病的晚期阶段出现。甚至更罕见,它们是未知转移性疾病的第一个迹象。然而,它们的发生总是对临床医生来说都是一个具有挑战性的情况,在处理非常不寻常的病变时,对于病理学家来说,在识别主站点时。我们回顾性研究了21例肺癌向头颈部转移的病例(16例男性和5例女性,年龄范围43-80岁;8例局限于牙龈[其中2例发生在种植体周围牙龈],七个到下颌下淋巴结,两个到下颌骨,三个到舌头,腮腺1例,8例,转移是隐匿性肺癌的第一个临床表现),并提出了一个广泛的免疫组织化学小组,用于正确识别原发性肿瘤的组织型,包括CK5/6、CK8/18、CK7、CK20、p40、p63、TTF-1、CDX2、嗜铬粒蛋白A、突触素,GATA-3,雌激素受体,PAX8,PSA。此外,我们从以前发表的研究中收集数据,并对相关文献进行了述评.
    Metastases from lung cancer to the oral cavity and to the head and neck generally are very infrequent and usually manifest in advanced stages of the disease. Even more rarely, they are the first sign of an unknown metastatic disease. Nevertheless, their occurrence always represents a challenging situation both for clinicians, in the management of very unusual lesions, and for pathologists, in the recognition of the primary site. We retrospectively studied 21 cases of metastases to the head and neck from lung cancer (sixteen males and five females, age range 43-80 years; eight cases localized to the gingiva [two of these to the peri-implant gingiva], seven to the sub-mandibular lymph nodes, two to the mandible, three to the tongue, one case to the parotid gland; in eight patients, metastasis was the first clinical manifestation of an occult lung cancer) and proposed a wide immunohistochemical panel for a proper identification of the primary tumor histotype, including CK5/6, CK8/18, CK7, CK20, p40, p63, TTF-1, CDX2, Chromogranin A, Synaptophysin, GATA-3, Estrogen Receptors, PAX8, PSA. Furthermore, we collected data from previously published studies and narratively reviewed the relevant literature.

    肺癌是全球癌症相关死亡的主要原因,在许多国家发病率都在增加。关于转移性肺癌患者的动脉和静脉血栓栓塞(ATE/VTE)的研究很少。我们的研究重点是IV期肺癌合并ATE或VTE患者的临床特征,以进一步探讨其危险因素和预后。2011年1月至2019年6月在江阴市某三级医院确诊为转移性肺癌的患者,中国。使用对数秩检验来揭示患有ATE或VTE的患者的存活率。采用单变量分析和多变量logistic回归分析ATE的危险因素。共有587名患者参加了我们的研究,包括52例VTE和48例ATE患者。ATE比VTE更早发生。ATE患者预后较差。多因素logistic回归分析显示年龄大、高血压史是ATE的独立危险因素。转移性肺癌患者发生VTE和ATE的风险较高。ATE发生较早,且预后较差。应注意可能发生血栓栓塞的转移性肺癌患者,尤其是ATE。
    Lung cancer is the leading cause of cancer-related mortality worldwide with an increasing incidence in many countries. There were few studies on arterial and venous thromboembolism (ATE/VTE) in patients with metastatic lung cancer. Our study focused on the clinical characteristics of stage IV lung cancer patients with ATE or VTE to further explore the risk factors and prognosis. Patients diagnosed with metastatic lung cancer were enrolled from January 2011 to June 2019 at a tertiary hospital in Jiangyin, China. Log-rank test was used to reveal the survival for patients with ATE or VTE. Univariable analysis and multivariable logistic regression were used to study the risk factors for ATE. A total of 587 patients were enrolled in our study, including 52 patients with VTE and 48 with ATE. ATE occurred earlier than VTE. Patients with ATE had a worse prognosis. Multivariable logistic regression revealed that older age and a history of hypertension were independent risk factors for ATE. Patients with metastatic lung cancer were at high risk of VTE and ATE. ATE occurred earlier and was associated with a worse prognosis. Attention should be paid to metastatic lung cancer patients who may develop thromboembolism, especially ATE.
