    未经证实:先前曾接受手术切除初始原发性肺癌的患者发生多原发性肺癌(MPLCs)的风险很高。这项研究的目的是比较立体定向放射治疗(SBRT)和手术之间的疗效和安全性。
    未经评估:在这项多中心回顾性研究中,纳入2013年1月至2020年8月期间接受SBRT或再次手术的N0M0时肿瘤直径小于或等于5.0cm的MPLC患者.主要终点是3年局部复发和治疗相关毒性。采用Kaplan-Meier法计算生存率。χ2检验适用于评估两个亚组患者之间分类变量的差异。
    UNASSIGNED:对来自三个学术癌症中心的203名患者(SBRT组73名,手术组130名)进行了评估,中位随访时间为38.3个月。累计1-,2-,局部区域复发的3年发生率为5.6%,SBRT组的7.0%和13.1%,与3.2%相比,手术组分别为4.8%和7.4%,分别为[危险比(HR),1.97;95%置信区间(CI),0.74-5.24;P=0.14]。癌症特异性生存率为95.9%,94.5%和88.1%对96.9%,SBRT组和手术组分别为94.6%和93.8%(HR,1.72;95%CI,0.67-4.44;P=0.23)。在SBRT组中,两名患者(2.7%)患有三级放射性肺炎,在手术组,4例(3.1%)患者发生3级并发症,四例在手术后90天内因肺炎或肺心病而过期。
    UNASSIGNED:SBRT是一种有效的治疗选择,与先前根治性手术切除后的MPLCs患者相比,其毒性有限,它可以被认为是这些患者的替代疗法。
    UNASSIGNED: Patients who previously underwent surgical resection of initial primary lung cancer are at a high risk of developing multiple primary lung cancers (MPLCs). The purpose of this study was to compare the efficacy and safety between stereotactic body radiation therapy (SBRT) and surgery for MPLCs patients after prior radical resection for the first lung cancers.
    UNASSIGNED: In this multicenter retrospective study, eligible MPLC patients with tumor diameter of 5.0 cm or less at N0M0 who underwent SBRT or reoperation between January 2013 and August 2020 were enrolled. The primary endpoint was the 3-year locoregional recurrence and treatment-related toxicity. Kaplan-Meier method was used to calculate survival rates. The χ2 test was adapted to assess the difference of categorical variables between the two subgroup patients.
    UNASSIGNED: A total of 203 (73 in the SBRT group and 130 in the surgery group) patients from three academic cancer centers were evaluated with a median follow-up of 38.3 months. The cumulative 1-, 2-, and 3-year incidences of locoregional recurrence were 5.6 %, 7.0 % and 13.1 % in the SBRT group versus 3.2 %, 4.8 % and 7.4 % in the surgery group, respectively [hazard ratio (HR), 1.97; 95 % confidence interval (CI), 0.74-5.24; P = 0.14]. The cancer-specific survival rates were 95.9 %, 94.5 % and 88.1 % versus 96.9 %, 94.6 % and 93.8 % in the SBRT and surgery groups respectively (HR, 1.72; 95 % CI, 0.67-4.44; P = 0.23). In the SBRT group, two patients (2.7 %) suffered from grade 3 radiation pneumonitis, while in the surgery group, grade 3 complications occurred in four (3.1 %) patients, and four cases were expired due to pneumonia or pulmonary heart disease within 90 days after surgery.
    UNASSIGNED: SBRT is an effective therapeutic option with limited toxicity compared to surgery for patients with MPLCs after prior radical surgical resection, and it could be considered as an alternative treatment for those patients.

    肝细胞癌(HCC)的发病率和死亡率已显示出不利的上升趋势在过去的二十年,特别是在发达国家。超过六分之一的患者在就诊时患有晚期HCC。全身治疗仍然是这些患者的首选治疗方法。目前的选择包括酪氨酸激酶抑制剂(TKIs)和免疫疗法。这篇综述旨在总结过去一年中使用几种新批准的药物进行系统治疗的快速发展领域的最新知识。索拉非尼仍然是丙型肝炎患者病因的一线治疗选择之一,中晚期肝癌阶段,和Child-Pugh类A.Lenvatinib是另一种一线药物,可能在非丙型肝炎病因和无门静脉血栓形成的晚期HCC中具有更好的疗效。对一线治疗不耐受的患者可能受益于nivolumab或pembrolizumab的免疫治疗。在那些一线治疗失败的人中,选择应基于与先前治疗相关的副作用,性能状态,和潜在的肝功能障碍。正在进行的研究正在研究单独的免疫疗法或与TKI联合的免疫疗法作为一线疗法。正在研究联合全身治疗和全身加局部区域治疗的几种二线选择。未来的研究应该集中在确定可靠的生物标志物,以预测对治疗的反应,并更好地对进展风险高的患者进行分层。多学科方法对于晚期HCC患者的成功预后至关重要。
    Hepatocellular carcinoma (HCC) incidence and mortality have shown an unfavorable upward trend over the last two decades, especially in developed countries. More than one-sixth of the patients have advanced HCC at presentation. Systemic therapy remains the treatment of choice for these patients. Current options include tyrosine kinase inhibitors (TKIs) and immunotherapy. This review aims to summarize current knowledge on the rapidly evolving field of systemic therapy with several newly approved medications over the last year. Sorafenib remains one of the first-line treatment choices for patients with hepatitis C etiology, intermediate to advanced HCC stage, and Child-Pugh class A. Lenvatinib is the other first-line drug that might have better efficacy in non-hepatitis C etiologies and advanced HCC without portal vein thrombosis. Patients intolerant to first-line therapy might benefit from immunotherapy with nivolumab or pembrolizumab. In those who fail first-line therapy, the choice should be based on the side effects related to previous treatment, performance status, and underlying liver dysfunction. Ongoing studies are investigating immunotherapy alone or immunotherapy in combination with TKIs as first-line therapy. Several second-line options for combination systemic therapy and systemic plus local-regional treatment are under investigation. Future studies should focus on identifying reliable biomarkers to predict response to therapy and to better stratify patients at high risk for progression. Multidisciplinary approach is pivotal for successful outcomes in patients with advanced HCC.

    胶质瘤患者血浆中的外泌体有望作为预后的生物标志物。我们旨在确定总外泌体蛋白和mRNA表达水平的变化是否可以作为接受抗肿瘤疫苗的神经胶质瘤患者免疫和临床反应的替代标记。从参加抗肿瘤疫苗I/II期试验的20/22名患者的疫苗前/后血浆样本中分离外泌体。分析外泌体蛋白质含量,并通过qRT-PCR同时评估24个基因的mRNA表达水平。使用Spearman等级统计和风险比(HR),外泌体蛋白和ΔCt值的疫苗接种前后变化与免疫和临床反应以及存活率相关。外泌体蛋白水平与诊断时的WHO肿瘤分级呈正相关(p<0.0043)。蛋白质水平在后-与疫苗接种前外泌体部分。治疗后肿瘤大小的增加与胶质母细胞瘤中外泌体蛋白的升高有关,但在间变性星形细胞瘤(AA)中并不总是如此。只有IL-8、TIMP-1、TGF-β和ZAP70的外泌体ΔCt值是显著的(p<0.04至p<0.001)。IL-8和TGF-βmRNA的ΔCt与疫苗后对神经胶质瘤抗原的免疫反应呈正相关,TIMP-1mRNA的ΔCt与IL-8和TGF-β的ΔCt呈负相关。只有IL-8的ΔCt与OS和进展时间(TTP)弱相关。在存活时间最长的AA患者的疫苗后外泌体中,PD-1的mRNA持续升高。血浆外泌体中免疫相关基因的蛋白质和mRNA表达水平可用于评估神经胶质瘤患者对疫苗接种疗法的反应。
    Exosomes in plasma of glioma patients hold promise as biomarkers of prognosis. We aimed to determine whether changes in total exosomal protein and mRNA expression levels could serve as surrogate markers of immunological and clinical responses in glioma patients receiving antitumor vaccines. Exosomes were isolated from pre/post-vaccine plasma specimens in 20/22 patients enrolled in a phase I/II trial with the antitumor vaccine. Exosomal protein content was analyzed and mRNA expression levels for 24 genes were simultaneously assessed by qRT-PCR. Pre- to post-vaccination changes in exosomal protein and ΔCt values were correlated with immunological and clinical responses and survival using Spearman rank statistics and hazard ratios (HR). Exosomal protein levels positively correlated (p < 0.0043) with the WHO tumor grade at diagnosis. Protein levels were lower in post- vs. pre-vaccination exosome fractions. Post-therapy increases in tumor size were associated with elevations in exosome proteins in glioblastoma but not always in anaplastic astrocytoma (AA). Only exosomal ΔCt values for IL-8, TIMP-1, TGF-β and ZAP70 were significant (p < 0.04 to p < 0.001). The ΔCt for IL-8 and TGF-β mRNA positively correlated with post-vaccine immunologic responses to glioma antigens, while ΔCt for TIMP-1 mRNA was negatively correlated to ΔCt for IL-8 and TGF-β. Only ΔCt for IL-8 weakly correlated with OS and time to progression (TTP). In post-vaccine exosomes of the longest surviving patient with AA, mRNA for PD-1 was persistently elevated. Protein and mRNA expression levels for immune-related genes in plasma exosomes were useful in evaluating glioma patients\' response to vaccination therapy.

    转移性三阴性乳腺癌(mTNBC)患者通常预后不良。这项研究的目的是前瞻性评估双周联合长春瑞滨和奥沙利铂(NVBOX)在二线或三线治疗mTNBC的疗效和毒性。符合条件的患者为18-70岁的女性,并且mTNBC在转移背景下经过1或2次先前的化疗方案后进展。每4周一次给予NVBOX,最多6个周期。主要终点是无进展生存期(PFS)。招募了44名患者。所有患者均暴露于蒽环类和/或紫杉烷类;56.8%的患者接受了顺式/碳铂预处理。在38名可评估的患者中,总缓解率为31.6%,7例持续≥6个月.中位PFS和总生存期(OS)分别为4.3(95%CI,3.6-5.0)个月和12.6(95%CI,8.1-17.0)个月,分别。从诊断到复发的时间间隔≤1y,并且招募前1-2个方案的进展时间(TTP)≤3个月的患者的PFS和OS明显缩短。对于34例接受二线治疗的患者,之前的铂金是显著影响NVBOXPFS的一个因素。3/4级血液学毒性包括中性粒细胞减少症(70.5%),血小板减少(27.3%)和贫血(15.9%)。最常见的3/4级非血液学毒性是便秘/腹胀(20.5%)和恶心/呕吐(13.6%)。我们得出的结论是,每两周一次的NVBOX方案在二线或三线mTNBC中具有良好的安全性,这需要在III期研究中进行进一步调查。该试验已在www上注册。clinicaltrials.gov(没有。NCT01528826)。
    Patients with metastatic triple-negative breast cancer (mTNBC) typically have a poor prognosis. The purpose of this study was to prospectively evaluate the efficacy and toxicity of biweekly combination of vinorelbine and oxaliplatin (NVBOX) in second- or third-line setting for mTNBC. Eligible patients were female with 18-70 y old, and had mTNBC that had progressed after 1or 2 prior chemotherapy regimens in the metastatic setting. NVBOX was given biweekly every 4 week for a maximum of 6 cycles. The primary endpoint was progression-free survival (PFS). Forty-4 patients were recruited. All patients had been exposed to anthracyclines and/or taxanes; 56.8% of patients were cis/carbo-platin pretreated. Among the 38 evaluable patients, overall response rate was 31.6% and 7 lasted ≥ 6 months. The median PFS and overall survival (OS) were 4.3 (95% CI, 3.6-5.0) months and 12.6 (95% CI, 8.1-17.0) months, respectively. PFS and OS was significantly shorter in patients with interval from diagnosis to recurrence ≤ 1 y and time to progression (TTP) of 1-2 previous regimens before recruitment ≤ 3 months. For 34 patients who were treated in second line setting, prior platinum was a factor significantly compromising the PFS of NVBOX. Grade 3/4 hematologic toxicities included neutropenia (70.5%), thrombocytopenia (27.3%) and anemia (15.9%). The most frequent grade 3/4 non-hematologic toxicities were constipation/abdominal distension (20.5%) and nausea/vomiting (13.6%). We conclude that biweekly NVBOX regimen is effective with a good safety profile in the second- or third-line mTNBC, which warrants further investigation in a phase III study. This trial was registered with www.clinicaltrials.gov (no. NCT01528826).

    多形性胶质母细胞瘤(GBM)是最常见的脑肿瘤类型,并且是致命的。这种疾病的社区治疗标准是肿瘤的总切除或次全切除,其次是辐射和替莫唑胺。在复发时,可以添加贝伐单抗以增加无进展生存期。在试图设计治疗GBM的新药时遇到了许多挑战,例如血脑屏障的存在是大多数药物不可渗透的。因此,在过去的几年中,注意力转向用于治疗这种破坏性疾病的免疫手段。EGFRvIII靶向已被证明是通过使用免疫系统攻击胶质母细胞瘤细胞的好方法。虽然还在发展中,这种方法有望成为免疫定制药物治疗脑癌的第一步。
    Glioblastoma Multiforme (GBM) is the most common type of brain tumor and it is uniformly fatal. The community standard of treatment for this disease is gross or subtotal resection of the tumor, followed by radiation and temozolomide. At recurrence bevacizumab can be added for increased progression free survival. Many challenges are encountered while trying to devise new drugs to treat GBM, such as the presence of the blood brain barrier which is impermeable to most drugs. Therefore in the past few years attention was turned to immunological means for the treatment of this devastating disease. EGFRvIII targeting has proven a good way to attack glioblastoma cells by using the immune system. Although in still in development, this approach holds the promise as a great first step toward immune-tailored drugs for the treatment of brain cancers.

    Currently, the backbone of therapy for metastatic disease is cytotoxic chemotherapy, along with the recent addition of targeted therapy based on molecular markers with KRAS testing. Despite the improvement in survival for metastatic colon cancer, newer agents are still needed. The clinical activity of TroVax in metastatic colon cancer has been studied in a small number of clinical trials. There is evidence that supports the vaccine\'s ability to induce humoral and cellular responses, as demonstrated by positive 5T4 and MVA-specific antibody titers and cellular proliferation assays. Future strategies should focus on investigating the immunomodulatory effects of chemotherapy in conjunction with TroVax, understanding the optimal dosing and schedule of the combination, and examining potential predictive biomarkers to determine which patients may benefit from immunotherapy from those who do not.
