    UNASSIGNED:我们阐明了阿特珠单抗和贝伐单抗(Ate/Bev)治疗的不可切除肝细胞癌(HCC)患者血清IL-6水平的临床和免疫学意义。
    UNASSIGNED:我们前瞻性招募了165例不可切除的HCC患者(发现队列:来自三个中心的84例患者;验证队列:来自一个中心的81例患者)。使用流式细胞术珠子阵列分析基线血液样品。使用RNA测序分析肿瘤免疫微环境。
    UNASSIGNED:在发现队列中,临床获益6个月(CB6m)定义为完全或部分缓解,或病情稳定≥6个月。在各种基于血液的生物标志物中,无CB6m的参与者的血清IL-6水平显着高于有CB6m的参与者(平均11.56vs.5.05pg/ml,p=0.02)。使用最大程度地选择排名统计信息,高IL-6的最佳临界值确定为18.49pg/ml,15.2%的参与者在基线时发现IL-6水平较高.在发现和验证队列中,与基线IL-6水平较低的参与者相比,基线IL-6水平较高的参与者在Ate/Bev治疗后的缓解率降低,无进展生存期和总生存期较差.在多变量Cox回归分析中,高IL-6水平的临床意义持续存在,即使在调整了各种混杂因素之后。IL-6水平高的参与者显示CD8T细胞分泌的干扰素-γ和肿瘤坏死因子-α减少。此外,过量的IL-6抑制细胞因子的产生和CD8+T细胞的增殖。最后,IL-6水平高的参与者表现出非T细胞炎症的免疫抑制肿瘤微环境.
    UASSIGNED:在Ate/Bev治疗后,高基线IL-6水平可能与不良临床结局和T细胞功能受损相关。
    UNASSIGNED:尽管对阿特珠单抗和贝伐单抗治疗有反应的肝细胞癌患者表现出良好的临床结局,其中一小部分仍然存在主要阻力。我们发现,在接受阿特珠单抗和贝伐单抗治疗的肝细胞癌患者中,高基线血清IL-6水平与不良临床结果和T细胞反应受损相关。
    UNASSIGNED: We elucidated the clinical and immunologic implications of serum IL-6 levels in patients with unresectable hepatocellular carcinoma (HCC) treated with atezolizumab and bevacizumab (Ate/Bev).
    UNASSIGNED: We prospectively enrolled 165 patients with unresectable HCC (discovery cohort: 84 patients from three centres; validation cohort: 81 patients from one centre). Baseline blood samples were analysed using a flow cytometric bead array. The tumour immune microenvironment was analysed using RNA sequencing.
    UNASSIGNED: In the discovery cohort, clinical benefit 6 months (CB6m) was defined as complete or partial response, or stable disease for ≥6 months. Among various blood-based biomarkers, serum IL-6 levels were significantly higher in participants without CB6m than in those with CB6m (mean 11.56 vs. 5.05 pg/ml, p = 0.02). Using maximally selected rank statistics, the optimal cut-off value for high IL-6 was determined as 18.49 pg/ml, and 15.2% of participants were found to have high IL-6 levels at baseline. In both the discovery and validation cohorts, participants with high baseline IL-6 levels had a reduced response rate and worse progression-free and overall survival after Ate/Bev treatment compared with those with low baseline IL-6 levels. In multivariable Cox regression analysis, the clinical implications of high IL-6 levels persisted, even after adjusting for various confounding factors. Participants with high IL-6 levels showed reduced interferon-γ and tumour necrosis factor-α secretion from CD8+ T cells. Moreover, excess IL-6 suppressed cytokine production and proliferation of CD8+ T cells. Finally, participants with high IL-6 levels exhibited a non-T-cell-inflamed immunosuppressive tumour microenvironment.
    UNASSIGNED: High baseline IL-6 levels can be associated with poor clinical outcomes and impaired T-cell function in patients with unresectable HCC after Ate/Bev treatment.
    UNASSIGNED: Although patients with hepatocellular carcinoma who respond to treatment with atezolizumab and bevacizumab exhibit favourable clinical outcomes, a fraction of these still experience primary resistance. We found that high baseline serum levels of IL-6 correlate with poor clinical outcomes and impaired T-cell response in patients with hepatocellular carcinoma treated with atezolizumab and bevacizumab.

    血栓形成是复发性自然流产(RSA)的重要缘由。血栓性疾病的治疗有利于RSA的预防。因此,我们探讨了补血中药的临床疗效,补肾镇静治疗RSA合并血栓形成倾向。回顾性分析190例RSA合并血栓性疾病患者采用不同治疗方法的临床转归。中药组采用补肾法治疗,活血疏胎中药和西药组用低分子肝素(LMWH)治疗,中药联合西药组用LMWH加中药补肾,血液激活和胎儿稳定。治疗后,血小板聚集率,与单纯中药和LMWH组相比,LMWH组的血浆D-二聚体和子宫动脉血流阻力显着降低(P<0.0167)。与其他组相比,LMWH加中药组明显加快了胎儿芽的生长(P<0.0167)。此外,LMWH加中药组改善中医证候积分(P<0.0167),显现出较好的临床疗效。在治疗期间,LMWH组中有5例患者发生了不良反应,但在简单草药和LMWH加草药组中没有发生不良反应。因此,我们的研究表明,对于RSA合并血栓形成的治疗,中草药加LMWH可以改善怀孕期间子宫的血液供应,并为胎儿的生长提供有利的环境。中药具有良好的疗效,不良反应少。
    Thrombophilia is an important cause of recurrent spontaneous abortion (RSA). The treatment of thrombophilia is beneficial to the prevention of RSA. Therefore, we explored the clinical effect of Chinese traditional herbs with the effects of invigorating the blood, tonifying the kidney and calming the fetus in the treatment of RSA complicated with thrombophilia. We retrospectively analyzed the clinical outcomes of 190 RSA patients combined with thrombophilia using different treatment methods. The traditional Chinese medicine group was treated with kidney-invigorating, blood-activating and fetus-soothing herbs and the western medicine group was treated with low molecular weight heparin (LMWH), and the traditional Chinese medicine combined with western medicine group was treated with LMWH plus Chinese traditional herbs with the effects of kidney tonifying, blood activating and fetus stabilizing. After treatments, platelet aggregation rate, plasma D-dimer and uterine artery blood flow resistance were significantly reduced in the LMWH plus herbs compared to the simple herbs and LMWH group (P < 0.0167). The LMWH plus herbs group significantly accelerated the growth of fetal bud compared with other groups (P < 0.0167). Moreover, the LMWH plus herbs group improved traditional Chinese medicine syndrome scores (P < 0.0167), showing a better clinical efficacy. Adverse reactions occurred in five patients in the LMWH group but not in the simple herbs and LMWH plus herbs group during the treatment period. Therefore, our study shows that for the treatment of RSA complicated with thrombophilia, Chinese traditional herbs plus LMWH can improve the blood supply of the uterus during pregnancy and contribute to a favorable environment for the growth of the fetus. Chinese traditional herbs exert a good curative effect with few adverse reactions.

    UNASSIGNED:我们研究了免疫检查点抑制剂(ICI)再激发在先前的全身性治疗中接受基于ICI治疗的肝细胞癌(HCC)患者的疗效和安全性。
    未经评估:在这个国际上,回顾性多中心研究,在14个机构接受至少两行基于ICI的治疗(ICI-1,ICI-2)的HCC患者符合资格.主要结果包括最佳总体反应和治疗相关不良事件。
    未经证实:在994名接受ICI治疗的患者中,共有58名患者(男性,n=41;71%),平均年龄为65.0±9.0岁。ICI-1和ICI-2的系统治疗线中位数为1(范围,1-4)和3(范围,2-9),分别。ICI-1和ICI-2使用的基于ICI的治疗包括单独的ICI(ICI-1,n=26,45%;ICI-2,n=4,7%),双重ICI方案(n=1,2%;n=12,21%),或ICI联合靶向治疗/抗VEGF(n=31,53%;n=42,72%)。大多数患者因进展而停用ICI-1(n=52,90%)。ICI-1的客观反应率为22%,ICI-2的客观反应率为26%。在患有进行性疾病的患者中,ICI-2的反应也是ICI-1的最佳总体反应(n=11/21;52%)。ICI-1和ICI-2的中位进展时间分别为5.4(95%CI3.0-7.7)个月和5.2(95%CI3.3-7.0)个月,分别。在9例(16%)和10例(17%)患者中观察到ICI-1和ICI-2的治疗相关不良事件为3-4级,分别。
    UNASSIGNED:ICI再激发是安全的,并且在相当比例的HCC患者中获得了治疗益处。这些数据为在前瞻性试验中一线免疫治疗进展的患者中研究基于ICI的方案提供了理论基础。
    UNASSIGNED:基于一线免疫检查点抑制剂(ICI)的晚期肝细胞癌(HCC)治疗后的治疗测序仍然是一个挑战,因为在免疫治疗预处理患者中没有研究可用的二线治疗方案。特别是,ICI再激发在HCC患者中的作用尚不清楚,由于缺乏前瞻性试验的数据.我们调查了ICI为基础的方案的疗效和安全性在肝癌患者的免疫治疗前,国际,多中心研究。我们的数据为研究基于ICI的治疗方案在一线免疫治疗进展患者中的作用的前瞻性试验提供了理论基础。
    UNASSIGNED: We investigated the efficacy and safety of immune checkpoint inhibitor (ICI) rechallenge in patients with hepatocellular carcinoma (HCC) who received ICI-based therapies in a previous systemic line.
    UNASSIGNED: In this international, retrospective multicenter study, patients with HCC who received at least two lines of ICI-based therapies (ICI-1, ICI-2) at 14 institutions were eligible. The main outcomes included best overall response and treatment-related adverse events.
    UNASSIGNED: Of 994 ICI-treated patients screened, a total of 58 patients (male, n = 41; 71%) with a mean age of 65.0±9.0 years were included. Median systemic treatment lines of ICI-1 and ICI-2 were 1 (range, 1-4) and 3 (range, 2-9), respectively. ICI-based therapies used at ICI-1 and ICI-2 included ICI alone (ICI-1, n = 26, 45%; ICI-2, n = 4, 7%), dual ICI regimens (n = 1, 2%; n = 12, 21%), or ICI combined with targeted therapies/anti-VEGF (n = 31, 53%; n = 42, 72%). Most patients discontinued ICI-1 due to progression (n = 52, 90%). Objective response rate was 22% at ICI-1 and 26% at ICI-2. Responses at ICI-2 were also seen in patients who had progressive disease as best overall response at ICI-1 (n = 11/21; 52%). Median time-to-progression at ICI-1 and ICI-2 was 5.4 (95% CI 3.0-7.7) months and 5.2 (95% CI 3.3-7.0) months, respectively. Treatment-related adverse events of grade 3-4 at ICI-1 and ICI-2 were observed in 9 (16%) and 10 (17%) patients, respectively.
    UNASSIGNED: ICI rechallenge was safe and resulted in a treatment benefit in a meaningful proportion of patients with HCC. These data provide a rationale for investigating ICI-based regimens in patients who progressed on first-line immunotherapy in prospective trials.
    UNASSIGNED: Therapeutic sequencing after first-line immune checkpoint inhibitor (ICI)-based therapy for advanced hepatocellular carcinoma (HCC) remains a challenge as no available second-line treatment options have been studied in immunotherapy-pretreated patients. Particularly, the role of ICI rechallenge in patients with HCC is unclear, as data from prospective trials are lacking. We investigated the efficacy and safety of ICI-based regimens in patients with HCC pretreated with immunotherapy in a retrospective, international, multicenter study. Our data provide the rationale for prospective trials investigating the role of ICI-based regimens in patients who have progressed on first-line immunotherapy.

    缺乏接受包括单独抗凝在内的药物治疗的Budd-Chairi综合征(BCS)患者的长期预后数据。
    连续患者(N=138,平均值[标准差,SD]年龄29.3[12.9]岁;66名男性)患有BCS,仅接受药物治疗,包括抗凝治疗,纳入最少随访12个月.初始反应被分类为完全(CR),部分(PR)或无应答(NR),并作为应答丧失(LoR)或应答维持(MoR)进行随访。基线的关联,评估了具有不同反应的临床和生化参数.
    76例患者(55.1%)有CR,26例(18.8%)有PR,36例(26.1%)有NR。具有PR或NR的人后来都没有CR。在中位随访40(范围12-174)个月时,LoR在PR组比CR组更常见(12[46.2%]vs18[23.7%],P=0.03)。LoR与腹水的存在相关(比值比[OR]1.5;95%置信区间[CI]0.06-0.71),基线和随访期间的胃肠道出血(OR1.33;95%CI0.09-0.82)或黄疸(OR1.01;95%CI0.11-0.97)(OR0.018;95%CI1.006-1.030)。NR(28[77.8%])死亡率高于CR(15[19.7%],P=0.001)和PR(8[30.8%],P=0.001)。在二元逻辑回归分析中,基线时腹水的存在与LoR相关(OR0.303[0.098-0.931]).
    初始CR患者的生存率优于无反应者。三分之一的人在后续行动中有LoR。基线时腹水的存在与LoR相关。
    UNASSIGNED: There is lack of data on long-term outcomes of patients with Budd-Chairi Syndrome (BCS) treated with medical therapy including anticoagulation alone.
    UNASSIGNED: Consecutive patients (N = 138, mean [standard deviation, SD] age 29.3 [12.9] years; 66 men) with BCS, treated with medical therapy alone including anticoagulation, with minimum follow-up of 12 months were included. Initial response was classified as complete (CR), partial (PR) or nonresponse (NR) and on follow-up as loss of response (LoR) or maintenance of response (MoR). The association of baseline, clinical and biochemical parameters with different responses was evaluated.
    UNASSIGNED: Seventy-six patients (55.1%) had CR, 26 (18.8%) had PR and 36 (26.1%) had NR. None with PR or NR had CR later. At a median follow-up of 40 (range 12-174) months, LoR was more common in PR group than in CR group (12 [46.2%] vs 18 [23.7%], P = 0.03). LoR was associated with presence of ascites (odds ratio [OR] 1.5; 95% confidence interval [CI] 0.06-0.71), gastrointestinal bleed (OR 1.33; 95% CI 0.09-0.82) or jaundice (OR 1.01; 95% CI 0.11-0.97) at baseline and duration of follow-up (OR 0.018; 95% CI 1.006-1.030). Mortality was higher in NR (28 [77.8%]) compared with CR (15 [19.7%], P = 0.001) and PR (8 [30.8%], P = 0.001). On binary logistic regression analysis, presence of ascites at baseline was associated with LoR (OR 0.303 [0.098-0.931]).
    UNASSIGNED: Patients with initial CR have better survival than nonresponders. One-third had LoR on follow-up. The presence of ascites at baseline is associated with LoR.

    UASSIGNED:由于通过成像的实体瘤(irRECIST)的免疫相关反应评估标准大大低估了对免疫治疗的客观反应,我们建立了基于肿瘤标志物(RecistTM)的实体瘤应答评估标准,以探讨RecistTM是否可以弥补irRECIST标准的缺陷.
    未经评估:这是一项观察性研究,它由两部分组成。第一部分(A组)是一项回顾性研究,包括恶性实体瘤患者。第二部分(B组)是一项前瞻性研究,EGFR阴性和ALK阴性的IIIB-IV期非小细胞肺癌患者接受一线治疗.从2017年1月到2020年9月,招募了一百一十名接受免疫治疗的肿瘤标志物增加三倍的患者。通过irRECIST和RecystTM评估对免疫疗法的治疗反应。功效,总生存期(OS),统计比较不同评价标准下的首次评价时间和最早响应时间。
    UNASSIGNED:通过RecystTM标准评估的治疗反应与通过irRECIST标准评估的治疗反应不一致(Kappa=0.386,p<0.001)。与irRECIST标准相比,RecystTM的完成反应(CR)率更高(20.9%vs1.8%,p<0.001)。RecystTM标准下的最早响应时间比irRECIST标准下的早3.42周(u=-5.233,p<0.001)。肿瘤标志物相关完全应答(tmCR)和肿瘤标志物相关部分应答(tmPR)的中位OS差异显著,以及tmPR和肿瘤标志物相关的稳定疾病(tmSD)之间(χ2=15.572,p<0.001;χ2=7.720,p=0.005),但不在tmSD和肿瘤标志物相关进展性疾病(tmPD)之间(χ2=1.596,p=0.206)。当同时应用这两个标准时,对于根据irRECIST标准患有免疫相关CR/免疫相关PR(irCR/irPR)(n=54)的患者,达到tmCR(n=22)和tmPR(n=32)的中位OS差异有统计学意义(χ2=14.011,p<0.001)。RecystTM标准可以比irRECIST标准更准确地预测1年和2年OS(AUC:0.862vs0.552,0.649vs0.521;两者均p<0.001)。在RecistTM中,已观察到4例患者的肿瘤标志物出现假性进展。
    未经评估:RecistTM标准可以有效区分CR,PR,SD,这可能有助于解决RECIST标准在评估免疫治疗反应方面的缺陷,特别是在评估患者是否可以尽快达到深度甚至完全的反应。
    UNASSIGNED:这项工作得到了重庆市卫生和计划生育委员会重点项目的支持(杨雪琴,2019ZDXM011)。
    UNASSIGNED: As the immune-related response evaluation criteria in solid tumors (irRECIST) by imaging greatly underestimated the objective response to immunotherapy, we established the response evaluation criteria in solid tumors based on tumor markers (RecistTM) to explore whether RecistTM can compensate for the deficiencies of the irRECIST criteria.
    UNASSIGNED: This was an observational study, which consisted of two parts. The first part (Group A) was a retrospective study including the patients with malignant solid tumors. The second part (Group B) was a prospective study, which were EGFR-negative and ALK-negative patients with stage IIIB-IV non-small cell lung cancer receiving first-line treatment. From January 2017 to September 2020, one hundred and ten patients with a three-time increase in tumor markers receiving immunotherapy were recruited. The treatment response to immunotherapy was evaluated by irRECIST and RecistTM. Efficacy, overall survival (OS), first evaluation time and earliest response time under the different evaluation criteria were compared by statistics.
    UNASSIGNED: The treatment response evaluated by the RecistTM criteria was not consistent with that evaluated by the irRECIST criteria (Kappa = 0.386, p < 0.001). RecistTM had a higher completed response (CR) rate compared to irRECIST criteria (20.9% vs 1.8%, p < 0.001). The earliest response time under the RecistTM criteria was 3.42 weeks earlier than that under the irRECIST criteria (u = -5.233, p < 0.001). There were significant differences in median OS between tumor marker-related complete response (tmCR) and tumor marker-related partial response (tmPR), as well as between tmPR and tumor marker-related stable disease (tmSD) (χ2 = 15.572, p < 0.001; χ2 = 7.720, p = 0.005), but not between tmSD and tumor marker-related progressive disease (tmPD) (χ2 = 1.596, p = 0.206). When applying both criteria together, for patients with immune-related CR / immune-related PR (irCR/irPR) (n = 54) under irRECIST criteria, there was a significant difference in median OS between achieving tmCR (n = 22) and tmPR (n = 32) (χ2 = 14.011, p < 0.001). RecistTM criteria can predict 1-year and 2-year OS more accurately than irRECIST criteria (AUCs:0.862 vs 0.552, 0.649 vs 0.521, respectively;both p < 0.001). In RecistTM, 4 patients had been observed with pseudoprogression in tumor markers.
    UNASSIGNED: The RecistTM criteria could effectively distinguish CR, PR, and SD, which may help resolve the shortcomings of the RECIST criteria in evaluating the treatment response to immunotherapy, especially in assessing whether patients can achieve deep or even complete response as soon as possible.
    UNASSIGNED: This work was supported by the Key projects of Chongqing Health and Family Planning Commission (to Xueqin Yang, 2019ZDXM011).

    接受DEB-TACE治疗的大型HCC(>5cm)患者进行回顾性分析。评估患者的客观反应(OR)和总生存期(OS),这是从DEB-TACE的第一个疗程到最后一次随访/死亡计算的。计算整个研究组的OR和OS,并在孤立性与多灶性HCC组成的亚组之间进行比较。单叶与双叶病,明确与不明确的HCC,同质增强的HCC与异质增强的HCC相比。
    25例患者进行了67例DEB-TACE手术(平均:每位患者2.7±1.4次)。平均病灶大小为9.9±4.5cm。25名患者中,13例(52%)患有多灶性HCC。单叶病见于15例患者(60%)。平均随访时间为24.4个月。或在6个月和12个月分别为56%和48%,分别,明确的病变显示更好的OR。中位OS为28个月(95%置信区间,12.3–43.6).12个月和24个月的OS率分别为92%和57%,分别。OS在明确定义的HCC和单叶疾病中被认为是优越的。
    在这项研究中,DEB-TACE已显示在具有保留的肝功能的大/多灶性HCC的患者中具有良好的反应。明确的HCC和单叶病具有更好的反应和生存率。
    UNASSIGNED: This study aimed to study the outcome and survival of patients with large hepatocellular carcinoma (HCC) receiving drug-eluting beads (DEBs) transarterial chemoembolization (TACE). In addition, tumor morphologies were correlated with the response and survival to analyze the association of morphology with the outcome.
    UNASSIGNED: Patients with large HCC (>5 cm) who underwent DEB-TACE for palliation were analyzed retrospectively. Patients were assessed for objective response (OR) and overall survival (OS), which was calculated from the first session of DEB-TACE to the last follow-up/death. OR and OS were calculated for the entire study group and were compared among the subgroups consisting of solitary versus multifocal HCC, unilobar versus bilobar disease, well-defined versus ill-defined HCC, and HCC with homogeneous enhancement versus HCC with heterogeneous enhancement.
    UNASSIGNED: Sixty-seven DEB-TACE procedures were performed in 25 patients (average: 2.7 ± 1.4 sessions per patient). The mean lesion size was 9.9 ± 4.5 cm. Of 25 patients, 13 (52%) had multifocal HCC. Unilobar disease was seen in 15 patients (60%). The mean duration of follow-up was 24.4 months. OR at 6 and 12 months were 56% and 48%, respectively, with well-defined lesions showing better OR. The median OS was 28 months (95% confidence interval, 12.3-43.6). OS rate at 12 and 24 months was 92% and 57%, respectively. OS was seen to be superior in well-defined HCC and unilobar disease.
    UNASSIGNED: In this study, DEB-TACE has shown to have a good response in patients having large/multifocal HCC with preserved liver functions. Well-defined HCC and unilobar disease have a better response and survival.

    在乳腺癌中,疼痛性骨转移是常见的。局部放疗是骨转移疼痛的标准治疗方法。单纯放疗的疼痛控制和总体反应率低。这项研究的目的是比较外束放疗与同期卡培他滨的安全性和有效性。乳腺癌患者疼痛骨转移的单独外束放疗控制。
    84例乳腺癌骨转移疼痛患者参与了这项前瞻性研究。我们将患者随机分为两组:A组接受10次30Gy的放射疗法治疗,B组每12小时接受卡培他滨825mg/m2治疗。同时使用相同的放射治疗剂量。
    关于早期治疗毒性,两组之间没有统计学上的显着差异。大多数毒性是胃肠道(腹泻和恶心)和轻度(I级或II级)。中位疼痛评分从第一周开始下降,在第4周有明显的反应。两组之间的中位疼痛评分差异具有统计学意义,p值=0.045。两组的中位镇痛评分在第12周具有统计学显著性,P值=0.032。A组和B组在第4周时对疼痛的完全缓解分别为19%和42.9%,分别。
    同步放化疗治疗乳腺癌疼痛性骨转移是可以耐受和安全的;与单纯放疗相比,它具有更高的总体缓解率和疼痛缓解率。
    BACKGROUND: In breast cancer, painful bone metastases are common. Local radiotherapy is the standard treatment of painful bone metastases. Pain control and overall response rateswere low in radiotherapy alone.The objectives of this study were to compare the safety and efficacy of external beam radiotherapy with concurrent capecitabine vs. external beam radiotherapy alone in pain control of painful bone metastases in breast cancer patients.
    METHODS: Eighty-four patients with painful bone metastases from breast cancer participated in this prospective study. We randomized the patients into two groups: group A treated with radiotherapy 30 Gy in 10 fractions and group B treated with capecitabine 825 mg/m2 every 12 hrs. concurrently with the same radiotherapy dose.
    RESULTS: There was no statistically significant difference between the two groups regarding early treatment toxicity. Most of the toxicity was gastrointestinal (diarrhea and nausea) and mild (grade I or II). The median pain score decreased from week one, and there was a marked response at week4. The difference in median pain score between both groups was statistically significant with p-value = 0.045. The median analgesic score in both groups was statistically significant with a p-value = 0.032 at week 12. A complete response to pain at week 4 was 19% and 42.9% in groups A and B, respectively.
    CONCLUSIONS: Concurrent chemoradiation in painful bone metastases from breast cancer origin was tolerable and safe; it had a higher overall response rate and pain palliation than radiotherapy alone.

    研究纹理分析和机器学习在肝转移患者介入前锥形束计算机断层扫描(CBCT)图像上预测经动脉放射栓塞(TARE)治疗反应的潜力。
    在这项IRB批准的回顾性单中心研究中,36例患者共104例肝转移(男性占56%,平均年龄61.1±13岁)在TARE之前接受CBCT检查,并在治疗后6个月进行随访成像。根据RECIST版本1.1评估治疗反应,并将其分为疾病控制(部分反应/稳定的疾病)与疾病进展(进行性疾病)。目标病变分割后,使用pyRadiomics软件包提取了对应于七个不同特征类的104个影像组学特征。在降维之后,在定制人工神经网络(ANN)上执行机器学习分类。对先前未看到的测试数据集进行10倍交叉验证。
    来自TARE的平均施用累积活性为1.6Gbq(±0.5Gbq)。在平均5.9±0.8个月的随访中,82%的转移灶实现了疾病控制。降维后,104个(15%)纹理分析特征中的15个仍用于进一步分析。在以前看不见的一组肝转移瘤中,多层感知器ANN的灵敏度为94.2%,特异性为67.7%,受试者工作特征曲线下面积为0.85。
    我们的研究表明,基于纹理分析的机器学习可能具有使用肝转移患者的治疗前CBCT图像来预测对TARE的治疗反应的潜力。

    UNASSIGNED: In this IRB-approved retrospective single-center study 36 patients with a total of 104 liver metastases (56 % male, mean age 61.1 ± 13 years) underwent CBCT prior to TARE and follow-up imaging 6 months after therapy. Treatment response was evaluated according to RECIST version 1.1 and dichotomized into disease control (partial response/stable disease) versus disease progression (progressive disease). After target lesion segmentation, 104 radiomics features corresponding to seven different feature classes were extracted with the pyRadiomics package. After dimension reduction machine learning classifications were performed on a custom artificial neural network (ANN). Ten-fold cross validation on a previously unseen test data set was performed.
    UNASSIGNED: The average administered cumulative activity from TARE was 1.6 Gbq (± 0.5 Gbq). At a mean follow-up of 5.9 ± 0.8 months disease control was achieved in 82 % of metastases. After dimension reduction, 15 of 104 (15 %) texture analysis features remained for further analysis. On a previously unseen set of liver metastases the Multilayer Perceptron ANN yielded a sensitivity of 94.2 %, specificity of 67.7 % and an area-under-the receiver operating characteristics curve of 0.85.
    UNASSIGNED: Our study indicates that texture analysis-based machine learning may has potential to predict treatment response to TARE using pre-treatment CBCT images of patients with liver metastases with high accuracy.

    免疫检查点抑制剂(ICIs)在临床上用于治疗晚期肺癌,在临床试验中,一些患者使用ICI治疗已达到完全缓解(CR)。然而,总结此类患者临床病程的报告有限.我们报告了两例肺腺癌,其中一线pembrolizumab单药治疗达到CR,治疗完成后维持治疗效果。特定患者可以达到CR,即使是那些不符合先前报道的治疗反应预测因子的人,除了高程序性死亡-配体1表达。因此,可以准确预测ICIs临床疗效的生物标志物是必要的.
    Immune checkpoint inhibitors (ICIs) are clinically used for treating advanced lung cancer, and some patients have achieved complete remission (CR) with ICI therapy in clinical trials. However, reports summarizing the clinical courses of such patients are limited. We report two cases of lung adenocarcinoma in which CR was achieved with first-line pembrolizumab monotherapy, and the therapeutic effect was maintained after treatment completion. Specific patients can achieve CR, even those who do not meet the previously reported predictors of treatment response other than high programmed death-ligand 1 expression. Thus, biomarkers that can accurately predict the clinical efficacy of ICIs are warranted.

    UNASSIGNED: The albumin-bilirubin (ALBI) grade/score is derived from a validated nomogram to objectively assess prognosis and liver function in patients with hepatocellular carcinoma (HCC). In this post hoc analysis, we assessed prognosis in terms of survival by baseline ALBI grade and monitored liver function during treatment with ramucirumab or placebo using the ALBI score in patients with advanced HCC.
    UNASSIGNED: Patients with advanced HCC, Child-Pugh class A with prior sorafenib treatment were randomised in REACH trials to receive ramucirumab 8 mg/kg or placebo every 2 weeks. Data were analysed by trial and as a meta-analysis of individual patient-level data (pooled population) from REACH (alpha-fetoprotein ≥400 ng/ml) and REACH-2. Patients from REACH with Child-Pugh class B were analysed as a separate cohort. The ALBI grades and scores were calculated at baseline and before each treatment cycle.
    UNASSIGNED: Baseline characteristics by ALBI grade were balanced between treatment arms among patients in the pooled population (ALBI-1, n = 231; ALBI-2, n = 296; ALBI-3, n = 7). Baseline ALBI grade was prognostic for overall survival (OS; ALBI grade 2 vs. 1; hazard ratio [HR]: 1.38 [1.13-1.69]), after adjusting for other significant prognostic factors. Mean ALBI scores remained stable in both treatment arms compared with baseline and were unaffected by baseline ALBI grade, macrovascular invasion, tumour response, geographical region, or prior locoregional therapy. Baseline ALBI grades 2 and 3 were associated with increased incidence of liver-specific adverse events and discontinuation rates in both treatments. Ramucirumab improved OS in patients with baseline ALBI grade 1 (HR 0.605 [0.445-0.824]) and ALBI grade 2 (HR 0.814 [0.630-1.051]).
    UNASSIGNED: Compared with placebo, ramucirumab did not negatively impact liver function and improved survival irrespective of baseline ALBI grade.
    UNASSIGNED: Hepatocellular carcinoma is the third leading cause of cancer-related death worldwide. Prognosis is affected by many clinical factors including liver function both before and during anticancer treatment. Here we have used a validated approach to assess liver function using 2 laboratory parameters, serum albumin and bilirubin (ALBI), both before and during treatment with ramucirumab in 2 phase III placebo-controlled studies. We confirm the practicality of using this more simplistic approach in assessing liver function prior to and during anticancer therapy, and demonstrate ramucirumab did not impair liver function when compared with placebo.
