  • 文章类型: Journal Article
    目前,广泛期小细胞肺癌(ES-SCLC)患者缺乏有效的二线治疗和后续治疗,标准化治疗方案的建立仍在进行中。考虑到抗血管生成药物和免疫检查点抑制剂(ICIs)的潜在协同治疗作用,联合治疗可能是治疗肺癌的可行选择.本研究集中于评估安洛替尼与ICIs联合治疗ES-SCLC的疗效和安全性。我们对2020年4月至2023年4月在浙江省肿瘤医院接受安洛替尼联合ICIs作为二线和后续治疗的广泛期SCLC患者进行了回顾性分析。使用Kaplan-Meier方法分析生存率。在接受联合治疗的43名患者中,没有完全缓解(CR)的病例,16例获得部分缓解(PR)的患者,21例疾病稳定(SD)患者,和6例经历疾病进展(PD)的患者。这导致了37.2%(16/43)的总体反应率(ORR)和86.0%(34/43)的疾病控制率(DCR)。中位无进展生存期(PFS)为4.0个月(95%CI:2.74-5.26),中位总生存期(OS)为10个月(95%CI:4.8-15.2).Cox多因素回归分析显示,性能评分(PS)和转移器官数量是影响ES-SCLCPFS的独立因素(p<0.001)。联合治疗表现出可接受的毒性,总的3/4级毒性率为30.2%。联合治疗显示与一些不良事件有显著关联,包括手足综合征,高血压,和疲劳,这是最重要的。安洛替尼与免疫检查点抑制剂联合治疗二线和随后的广泛期小细胞肺癌已显示出良好的疗效和安全性。
    Currently, there is a lack of effective second-line and subsequent treatments for patients with extensive-stage small-cell lung cancer (ES-SCLC), and the establishment of a standardized treatment protocol is still underway. Considering the potential synergistic therapeutic effects of anti-angiogenic drugs and immune checkpoint inhibitors (ICIs), combination therapy could be a viable option for treating lung cancer. This research concentrates on assessing the efficacy and safety of anlotinib in combination with ICIs for the treatment of ES-SCLC. We undertook a retrospective analysis of patients with extensive-stage SCLC who received anlotinib in combination with ICIs as second-line and subsequent treatment at Zhejiang Cancer Hospital between April 2020 and April 2023. Survival rates were analyzed using the Kaplan-Meier method. Among the 43 patients who received combination therapy, there were no cases of complete response (CR), 16 patients who achieved partial response (PR), 21 patients who had stable disease (SD), and 6 patients who experienced disease progression (PD). This resulted in an overall response rate (ORR) of 37.2% (16/43) and a disease control rate (DCR) of 86.0% (34/43). The median progression-free survival (PFS) was 4.0 months (95% CI: 2.74-5.26), and the median overall survival (OS) time was 10 months (95% CI: 4.8-15.2). Cox multifactorial regression analysis disclosed that the performance score (PS) and the number of metastatic organs were independent factors influencing PFS in ES-SCLC (p<0.001). The combination therapy demonstrated acceptable toxicity, with a total grade 3/4 toxicity rate of 30.2%. The combination therapy showed a notable association with several adverse events, including hand-foot syndrome, hypertension, and fatigue, which were the most significant. Combining anlotinib with immune checkpoint inhibitors has demonstrated favorable efficacy and safety in the treatment of second-line and subsequent extensive-stage small-cell lung cancer.

    肠道菌群影响对免疫检查点抑制剂(ICI)的反应。在多种癌症类型中,高水平的普氏粪杆菌与ICI的阳性反应有关。这里,基于粪便猎枪宏基因组学数据,我们在两个独立的非小细胞肺癌和晚期黑色素瘤患者队列中显示,基线时高水平的普氏F.在MCA205荷瘤小鼠中,施用F.prausnitzii菌株EXL01,已经在炎症性肠病的临床开发中,在临床和肿瘤转录组学水平上,在抗生素诱导的微生物群扰动的背景下恢复对ICI的抗肿瘤反应。体外,在ICI存在下,EXL01菌株增强T细胞活化。有趣的是,口服EXL01菌株不会引起粪便微生物群多样性或组成的任何变化,提示对小肠中的免疫细胞有直接影响。F.prausnitzii菌株EXL01将在不久的将来被评估为多种癌症中ICI的佐剂。
    Gut microbiota impacts responses to immune checkpoint inhibitors (ICI). A high level of Faecalibacterium prausnitzii have been associated with a positive response to ICI in multiple cancer types. Here, based on fecal shotgun metagenomics data, we show in two independent cohorts of patients with non-small cell lung cancer and advanced melanoma that a high level of F. prausnitzii at baseline is positively associated with a better clinical response to ICI. In MCA205 tumor-bearing mice, administration of F. prausnitzii strain EXL01, already in clinical development for Inflammatory Bowel Disease, restores the anti-tumor response to ICI in the context of antibiotic-induced microbiota perturbation at clinical and tumor transcriptomics level. In vitro, EXL01 strain enhances T cell activation in the presence of ICI. Interestingly, oral administration of EXL01 strain did not induce any change in fecal microbiota diversity or composition, suggesting a direct effect on immune cells in the small intestine. F. prausnitzii strain EXL01 will be evaluated as an adjuvant to ICI in multiple cancers in the near future.

    骨转移(BoMs)在转移性非小细胞肺癌(NSCLC)患者中普遍存在,关于BoM对免疫检查点抑制剂(ICIs)的反应的数据有限.这项研究的目的是比较BoMs对ICIs的成像反应与内脏转移的反应,并评估BoMs对生存的影响。
    回顾,多中心队列研究是在阿尔伯塔省接受纳武单抗或派博利珠单抗治疗的NSCLC患者中进行的,加拿大从2015年到2020年。主要终点是骨与内脏转移的真实世界器官特异性无进展生存期(osPFS)。内脏转移被归类为肾上腺,大脑,肝脏,肺,淋巴结,或其他腹内病变。次要结果是有和没有BoM的患者的总生存期(OS)。
    总共包括573例患者,其中所有患者均有内脏转移,243例患者(42.4%)有BoM。268例患者(46.8%)中发现PD-L1高表达。骨之间的osPFS没有显着差异,肝脏,和腹腔内转移(分别为p=0.20和p=0.76),与所有显示比其他疾病部位更短的osPFS。PD-L1高表达患者胸外部位的osPFS无差异。内脏疾病反应和骨病对ICI的反应之间存在显著的不一致(p=0.047)。BoM的存在是OS的独立不良预后因素(HR1.26,95CI:1.05-1.53,p=0.01)。
    转移骨,肝脏,与其他疾病部位相比,腹腔内病变对ICI的临床反应较差。此外,骨转移和肝转移是影响总生存期的独立不良预后因素.这些现实世界的数据表明,BoM对ICI的反应较差,可能需要治疗辅助手段来控制疾病。
    UNASSIGNED: Bone metastases (BoMs) are prevalent in patients with metastatic non-small-cell lung cancer (NSCLC) however, there are limited data detailing how BoMs respond to immune checkpoint inhibitors (ICIs). The purpose of this study was to compare the imaging response to ICIs of BoMs against visceral metastases and to evaluate the effect of BoMs on survival.
    UNASSIGNED: A retrospective, multicentre cohort study was conducted in patients with NSCLC treated with nivolumab or pembrolizumab in Alberta, Canada from 2015 to 2020. The primary endpoint was the real-world organ specific progression free survival (osPFS) of bone versus visceral metastases. Visceral metastases were categorized as adrenal, brain, liver, lung, lymph node, or other intra-abdominal lesions. The secondary outcome was overall survival (OS) amongst patients with and without BoMs.
    UNASSIGNED: A total of 573 patients were included of which all patients had visceral metastases and 243 patients (42.4%) had BoMs. High PD-L1 expression was identified in 268 patients (46.8%). No significant difference in osPFS was observed between bone, liver, and intra-abdominal metastases (p=0.20 and p=0.76, respectively), with all showing shorter osPFS than other disease sites. There was no difference in the osPFS of extra-thoracic sites of disease in patients with high PD-L1 expression. There was significant discordance between visceral disease response and bone disease response to ICI (p=0.047). The presence of BoMs was an independent poor prognostic factor for OS (HR 1.26, 95%CI: 1.05-1.53, p=0.01).
    UNASSIGNED: Metastatic bone, liver, and intra-abdominal lesions demonstrated inferior clinical responses to ICI relative to other sites of disease. Additionally, the presence of bone and liver metastases were independent poor prognostic factors for overall survival. This real-world data suggests that BoMs respond poorly to ICI and may require treatment adjuncts for disease control.

    靶向治疗和免疫治疗在非小细胞肺癌(NSCLC)的治疗中都很重要。准确的诊断和精确的治疗是实现患者长期生存的关键。MET融合是一种罕见的致癌因子,其最佳检测和治疗尚未建立。这里,我们报道了1例32岁女性肺腺癌患者,通过基于DNA的下一代测序(NGS)检测到PD-L1阳性和驱动基因阴性.化疗联合PD-1检查点抑制剂给药后根治性切除原发灶,根据她的病理反应和快速复发,表明原发性免疫抵抗。通过基于RNA的NGS检测到一种罕见的CD47-MET,荧光原位杂交证实了这一点。多重免疫荧光显示PD-L1相关的异质性免疫抑制微环境,几乎没有CD4T细胞和CD8T细胞分布。Savolitinib治疗导致无进展生存期(PFS)>12个月,直到疾病进展后通过重新活检和基于DNA-RNA的联合NGS在METp.D1228H中检测到新的继发性耐药突变.在这种情况下,CD47-MET融合非小细胞肺癌主要对免疫疗法耐药,对savolitinib敏感,靶向治疗后出现继发性METp.D1228H突变。基于DNA-RNA的NGS可用于检测此类分子事件和跟踪耐药性中的次级突变。为此,基于DNA-RNA的NGS可能在指导该患者人群的精确诊断和个体化治疗方面具有更好的价值。
    Targeted therapy and immunotherapy are both important in the treatment of non-small-cell lung cancer (NSCLC). Accurate diagnose and precise treatment are key in achieving long survival of patients. MET fusion is a rare oncogenic factor, whose optimal detection and treatment are not well established. Here, we report on a 32-year-old female lung adenocarcinoma patient with positive PD-L1 and negative driver gene detected by DNA-based next-generation sequencing (NGS). A radical resection of the primary lesion after chemotherapy combined with PD-1 checkpoint inhibitor administration indicated primary immuno-resistance according to her pathological response and rapid relapse. A rare CD47-MET was detected by RNA-based NGS, which was confirmed by fluorescence in situ hybridization. Multiplex immunofluorescence revealed a PD-L1 related heterogeneous immunosuppressive microenvironment with little distribution of CD4+ T cells and CD8+ T cells. Savolitinib therapy resulted in a progression-free survival (PFS) of >12 months, until a new secondary resistance mutation in MET p.D1228H was detected by re-biopsy and joint DNA-RNA-based NGS after disease progression. In this case, CD47-MET fusion NSCLC was primarily resistant to immunotherapy, sensitive to savolitinib, and developed secondary MET p.D1228H mutation after targeted treatment. DNA-RNA-based NGS is useful in the detection of such molecular events and tracking of secondary mutations in drug resistance. To this end, DNA-RNA-based NGS may be of better value in guiding precise diagnosis and individualized treatment in this patient population.

    免疫检查点抑制剂(ICIs)在肺癌的治疗中显示出独特的优势,并广泛应用于免疫治疗时代。然而,ICIs可引起不良反应。免疫疗法引起的血液毒性相对罕见。粒细胞缺乏症,与免疫检查点抑制剂相关的罕见血液学不良事件,在治疗和患者人口统计学方面受到的关注有限。在这里,我们报道了1例68岁男性非小细胞肺癌(NSCLC)患者,他接受了2个周期的程序性细胞死亡-1(PD-1)抗体sintilimab免疫治疗联合白蛋白结合型紫杉醇和卡铂化疗和1个周期的sintilimab单药治疗.在前两个治疗周期后,他被诊断为4级中性粒细胞减少症和败血症(伴有发烧和发冷症状)。替考拉宁迅速开始作为抗菌治疗。患者出现突然高热,并在第三个治疗周期开始当天出现粒细胞缺乏症,以绝对中性粒细胞计数为0.0×109/L为特征。患者接受粒细胞集落刺激因子治疗,但未显示改善。然后他接受了皮质类固醇治疗,中性粒细胞绝对计数逐渐恢复正常水平。据我们所知,这是在NSCLC患者中报道的首例sintilmab诱导的粒细胞缺乏症。Sindilimab引起的严重中性粒细胞减少症或粒细胞缺乏症是一种罕见的副作用,应与化疗引起的中性粒细胞减少症区分开来,并采用适当的疗法及时治疗;否则,情况可能会恶化。
    Immune checkpoint inhibitors (ICIs) demonstrate unique advantages in the treatment of lung cancer and are widely used in the era of immunotherapy. However, ICIs can cause adverse reactions. Hematological toxicities induced by immunotherapy are relatively rare. Agranulocytosis, a rare hematologic adverse event associated with immune checkpoint inhibitors, has received limited attention in terms of treatment and patient demographics. Herein, we report the case of a 68-year-old male with non-small cell lung cancer(NSCLC) who received two cycles of programmed cell death-1 (PD-1) antibody sintilimab immunotherapy combined with albumin-bound paclitaxel and carboplatin chemotherapy and one cycle of sintilimab monotherapy. He was diagnosed with grade 4 neutropenia and sepsis (with symptoms of fever and chills) after the first two cycles of treatment. Teicoplanin was promptly initiated as antimicrobial therapy. The patient presented with sudden high fever and developed agranulocytosis on the day of the third cycle of treatment initiation, characterized by an absolute neutrophil count of 0.0×109/L. The patient was treated with granulocyte colony-stimulating factor but did not show improvement. He was then treated with corticosteroids, and absolute neutrophil counts gradually returned to normal levels. To the best of our knowledge, this is the first reported case of sintilimab-induced agranulocytosis in a patient with NSCLC. Sintilimab-induced severe neutropenia or agranulocytosis is a rare side effect that should be distinguished from chemotherapy-induced neutropenia and treated promptly with appropriate therapies; otherwise, the condition may worsen.

    背景:黑色素瘤,一种致命的皮肤癌,在过去的几十年里,发病率显著上升。尽管在治疗方面取得了进展,它仍然是癌症死亡的重要原因。了解黑素瘤死亡率的人口趋势和变化对于解决差异和实施有效的干预措施至关重要。
    方法:使用疾病控制中心广泛的流行病学研究在线数据(CDCWONDER)数据库,我们分析了1999年至2020年美国黑色素瘤死亡率数据.数据按人口统计和区域变量分层,并计算了按年龄调整的死亡率.进行描述性分析,并采用Joinpoint回归分析来识别时间趋势。
    结果:在1999年至2020年之间,美国总共有184,416例黑色素瘤相关死亡,年龄调整后的死亡率从每10万人中的2.7下降到2.0,每年下降1.3%,不同人口群体和地区的差异很大。男人,非西班牙裔白人,年龄>65岁的人死亡率更高。非西班牙裔白人个体注意到2013年后AAMR以每年-6.1%的速度急剧下降。差异是通过地理密度看到的,与城市和郊区人口相比,农村人口的死亡率更高。
    结论:该研究强调了自2013年以来美国黑色素瘤死亡率的显着降低,这可能归因于诊断技术的进步,例如皮肤镜检查和免疫检查点抑制剂的引入。差距依然存在,尤其是农村人口。有针对性的干预措施侧重于增加筛查和教育是必要的,以进一步减轻黑色素瘤死亡率和解决人口差异。
    BACKGROUND: Melanoma, a deadly form of skin cancer, has witnessed a notable increase in incidence over the past decades. Despite advancements in treatment, it remains a significant cause of cancer mortality. Understanding demographic trends and variations in melanoma mortality is crucial for addressing disparities and implementing effective interventions.
    METHODS: Using the Centers for Disease Control Wide Ranging Online Data for Epidemiologic Research (CDC WONDER) database, we analyzed melanoma mortality data in the United States from 1999 to 2020. Data were stratified by demographic and regional variables, and age-adjusted mortality rates were calculated. Descriptive analysis was performed and Joinpoint regression analysis was employed to identify temporal trends.
    RESULTS: Between 1999 and 2020, there were 184,416 melanoma-related deaths in the United States Overall, the age-adjusted mortality rate declined from 2.7 to 2.0 per 100,000 people at a rate of -1.3% annually, with significant variations across demographic groups and regions. Men, non-Hispanic White individuals, and those aged > 65 experienced higher mortality rates. Non-Hispanic White individuals noted the steepest decrease in AAMR after 2013 at a rate of -6.1% annually. Disparities were seen by geographic density, with rural populations exhibiting higher mortality compared to their urban and suburban counterparts.
    CONCLUSIONS: The study highlights a significant reduction in melanoma mortality in the U.S. since 2013, potentially attributed to advancements in diagnostic techniques such as dermoscopy and the introduction of immune checkpoint inhibitors. Disparities persist, particularly among rural populations. Targeted interventions focusing on increased screening and education are warranted to further mitigate melanoma mortality and address demographic disparities.

    免疫检查点抑制剂(ICIs)已广泛用于各种癌症的早期治疗。为晚期癌症患者提供额外的治疗可能性。然而,某些患者人群容易受到ICI的毒性不良反应,比如甲状腺毒症,皮疹,在其他人中。具体来说,ICIDM,由免疫检查点抑制剂诱导,表现出与胰岛素依赖型糖尿病(1型糖尿病,T1DM)。ICIDM的特点是起病迅速,可能伴有严重的酮症酸中毒。尽管对胰岛素治疗反应良好,患者通常需要终身胰岛素依赖.在讨论了自身免疫不良反应和ICIs诱导的糖尿病(ICIDM)的特异性后,值得注意的是,某些患者群体特别容易受到ICI的毒性不良反应的影响.具体来说,ICIDM,这是由免疫检查点抑制剂触发的,反映胰岛素依赖型糖尿病的特征(1型糖尿病,T1DM)。本文对文献进行深入分析,探讨其发病机制,疾病进展,以及适用于免疫检查点抑制剂(ICIDM)诱导的糖尿病的治疗策略。
    Immune checkpoint inhibitors (ICIs) have become extensively utilized in the early-stage treatment of various cancers, offering additional therapeutic possibilities for patients with advanced cancer. However, certain patient populations are susceptible to experiencing toxic adverse effects from ICIs, such as thyrotoxicosis, rashes, among others. Specifically, ICIDM, induced by immune checkpoint inhibitors, exhibits characteristics similar to insulin-dependent diabetes mellitus (Type 1 Diabetes Mellitus, T1DM). ICIDM is characterized by a rapid onset and may coincide with severe ketoacidosis. Despite a favorable response to insulin therapy, patients typically require lifelong insulin dependence. After discussing the autoimmune adverse effects and the specifics of ICIs-induced diabetes mellitus (ICIDM), it is important to note that certain patient populations are particularly susceptible to experiencing toxic adverse effects from ICIs. Specifically, ICIDM, which is triggered by immune checkpoint inhibitors, mirrors the characteristics of insulin-dependent diabetes mellitus (Type 1 Diabetes Mellitus, T1DM). This article conducts an in-depth analysis of the literature to explore the pathogenesis, disease progression, and treatment strategies applicable to diabetes induced by immune checkpoint inhibitors (ICIDM).

    Lung cancer is a highly lethal malignant tumor worldwide and in China, with non-small cell lung cancer (NSCLC) accounting for approximately 85% of cases globally. In recent years, immune checkpoint inhibitor (ICI) had changed the paradigm of lung cancer treatment, either alone or in combination with chemotherapy and recomended as the first-line treatment for NSCLC. NSCLC patients often required glucocorticoid(GC) due to the cancer itself, tumor complications, or immune-related adverse event (irAE). GC had sparked debates on their impact on the therapeutic effectiveness of ICI in NSCLC patients as a substance with immunomodulatory effects. While some studies suggested that GC use did not influence patients survival, others argued the opposite. Understanding the effects of GC on immunotherapy is crucial for managing complaications in cancer patients and addressing irAE. This review explores the impact of GC on the efficacy of ICI in NSCLC patients, aiming to provide insights for clinical treatment.
    肺癌目前是世界上及我国病死率最高的恶性肿瘤之一,其中非小细胞肺癌(NSCLC)约占85%。近年来,免疫检查点抑制剂(ICI)在肺癌治疗中取得了较大的进展,ICI单独使用或联合化疗是NSCLC的一线治疗方式。肺癌患者由于疾病本身、肿瘤并发症或免疫不良相关事件(irAE)需要使用糖皮质激素(GC)。GC作为一种具有免疫调节作用的物质,是否会对NSCLC患者接受ICI的疗效产生影响目前尚存在争议。有研究认为使用GC不影响患者的生存时间,而部分研究观点相反。了解GC对于免疫治疗的影响将有助于管理肿瘤患者的并发症,治疗irAE等。本文就糖皮质激素对NSCLC患者接受ICI疗效的影响进行综述,为临床治疗提供参考。.

    Malignant pleural effusion (MPE) can be secondary to various advanced malignant tumors. Although systemic anti tumor therapy may be effective in primary tumors, it cannot reduce the accumulation of MPE in proportion of the patients. The interaction of tumor cells, immune cells, and mesenchymal cells, as well as the abnormal proliferation of tumor-associated blood vessels, together create an immunosuppressive microenvironment for MPE, which promotes the abnormal proliferation of tumor cells and the accumulation of MPE. With the in-depth study of the tumor microenvironment, the application of local systemic anti-tumor therapy with local intrathoracic application of immune checkpoint inhibitors, immune cells, cytokines, and gene-mediated cytotoxic immunotherapy are able to alleviate the immunosuppressive tumor microenvironment and inhibit the accumulation of MPE. This article aimed to describe the tumor microenvironment in MPE and provide clues for identifying novel therapeutic targets.
    恶性胸腔积液(malignant pleural effusion,MPE)可继发于多种晚期恶性肿瘤。尽管全身抗肿瘤治疗对原发肿瘤治疗有效,但仍有部分患者MPE控制不佳。肿瘤细胞、免疫细胞、间质细胞相互作用以及肿瘤相关血管异常增殖构建了MPE免疫抑制微环境,促进肿瘤细胞异常增殖和MPE的形成。随着对肿瘤微环境的深入研究,胸腔内局部应用免疫检查点抑制剂、免疫细胞及细胞因子和基因介导的细胞毒等免疫疗法可有效改善免疫抑制的肿瘤微环境,抑制MPE的形成。本文将阐述MPE的肿瘤微环境特征及相应的治疗新进展。.
