    背景:阴茎癌(PC)是一种致死性恶性肿瘤,没有有效的预后生物标志物。我们旨在研究鳞状细胞癌抗原(SCC-A)的轨迹与基于紫杉醇的化疗后患者预后之间的关联。ifosfamid,和顺铂(TIP)方案。
    方法:分析2014-2022年连续接受TIP化疗和重复SCC-A测量的AJCC分期III/IVPC患者。采用潜在类别生长混合(LCGM)模型来表征患者血清SCC-A轨迹。患者生存,并比较临床和病理肿瘤反应。使用逆概率处理加权来调整混杂因素。
    结果:纳入80例患者。LCGM模型确定了SCC-A的两种不同轨迹:低稳定(40%;n=32)和高下降(60%;n=48)。总生存率(HR[95%CI]:3.60[1.23-10.53],p=0.019),无进展生存期(HR[95%CI]:11.33[3.19-40.3],p<0.001),客观反应率(37.5%vs.62.5%p=0.028),疾病控制率(60.4%vs.96.9%p<0.00),和病理完全缓解率(21.2%vs.51.9%,p=0.014)在高下降臂中明显更差。
    结论:PC患者SCC-A变化率与TIP化疗后肿瘤反应和患者生存期相关。SCC-A可能有助于全身治疗后的肿瘤监测。
    BACKGROUND: Penile cancer (PC) is a lethal malignancy with no effective prognostic biomarker. We aim to investigate associations between trajectories of squamous cell carcinoma antigen (SCC-A) and patient outcomes after chemotherapy based on paclitaxel, ifosfamid, and cisplatin (TIP) regimen.
    METHODS: Consecutive AJCC staging III/IV PC patients who received TIP chemotherapy and repeated SCC-A measurements in 2014-2022 were analyzed. Latent class growth mixed (LCGM) models were employed to characterize patients\' serum SCC-A trajectories. Patient survival, and clinical and pathological tumor responses were compared. Inverse probability treatment weighting was used to adjust confounding factors.
    RESULTS: Eighty patients were included. LCGM models identified two distinct trajectories of SCC-A: low-stable (40%; n = 32) and high-decline (60%; n = 48). Overall survival (HR [95% CI]: 3.60 [1.23-10.53], p = 0.019), progression-free survival (HR [95% CI]: 11.33 [3.19-40.3], p < 0.001), objective response rate (37.5% vs. 62.5% p = 0.028), disease control rate (60.4% vs. 96.9% p < 0.00), and pathological complete response rate (21.2% vs. 51.9%, p = 0.014) were significantly worse in the high-decline arm.
    CONCLUSIONS: PC patients\' SCC-A change rate was associated with tumor response and patient survival after TIP chemotherapy. SCC-A might assist tumor monitoring after systemic therapies.

    目的:药物洗脱微珠经肝动脉化疗栓塞(DEB-TACE)与常规TACE(c-TACE)治疗不可切除肝内胆管癌(ICC)的疗效和安全性存在争议。因此,我们旨在比较ICC患者中c-TACE和DEB-TACE的疗效和安全性.
    方法:2016年6月10日至2022年11月19日,连续病理诊断为ICC的患者根据接受TACE治疗的类型分为DEB-TACE组和c-TACE组。采用Kaplan-Meier法和log-rank检验比较两组总生存期(OS)。倾向评分匹配(PSM)用于平衡c-TACE组和DEB-TACE组之间的特征。
    结果:本研究共纳入132例患者,c-TACE组64例,DEB-TACE组68例。c-TACE和DEB-TACE的中位OS为5个月和12个月,分别。c-TACE和DEB-TACE的客观有效率(ORR)分别为0%和66.2%,疾病控制率(DCR)分别为37.5%和91.2%。c-TACE和DEB-TACE治疗后3个月不良反应比较差异无统计学意义(P>0.05)。PSM后结果保持一致。Cox回归表明DEB-TACE是OS的独立保护因素。
    结论:DEB-TACE组比c-TACE组有更长的OS和更高的ORR和DCR,但两组在不良反应方面无显著差异.
    OBJECTIVE: The efficacy and safety of drug-eluting bead transarterial chemoembolization (DEB-TACE) and conventional TACE (c-TACE) in the treatment of patients with unresectable intrahepatic cholangiocarcinoma (ICC) remained controversial. Therefore, we aimed to compare the efficacy and safety between c-TACE and DEB-TACE among patients with ICC.
    METHODS: Between June 10, 2016 and November 19, 2022, consecutive patients with pathological diagnoses of ICC were divided into the DEB-TACE group and the c-TACE group based on the type of TACE treatment they received. The Kaplan-Meier method and log-rank test were used to compare overall survival (OS) between the two groups. Propensity score matching (PSM) was used to balance the characteristics between the c-TACE group and the DEB-TACE group.
    RESULTS: A total of 132 patients were included in this study, with 64 patients in the c-TACE group and 68 patients in the DEB-TACE group. The median OS for c-TACE and DEB-TACE was 5 and 12 months, respectively. The objective response rate (ORR) for c-TACE and DEB-TACE was 0 % and 66.2 %, respectively; the disease control rate (DCR) was 37.5 % and 91.2 %. There were no significant differences between c-TACE and DEB-TACE among adverse effects at 3 months after treatment (P > 0.05). The results remained consistent after PSM. The Cox regression demonstrated that the DEB-TACE was an independent protective factor for OS.
    CONCLUSIONS: Patients in the DEB-TACE group had longer OS and higher ORR and DCR than those in the c-TACE group, but no significant difference was observed between the two groups regarding adverse effects.

    评估化疗和免疫检查点抑制剂新辅助治疗局部晚期下咽癌(LAHPC)的疗效和喉功能保留。
    我们回顾性收集了2022年2月至2023年6月之间诊断的LAHPC患者。患者接受了化疗和免疫检查点抑制剂的组合作为新辅助治疗。对治疗的反应,喉功能保存率,并评估了短期生存率。
    共纳入20例患者。在这些病人中,17人(85.0%)患有IVA-B期疾病。10例(50%)和4例(20%)患者对原发肿瘤取得病理完全缓解(PCR)和主要病理缓解(MPR),分别。此外,6例患者出现不完全病理反应(IPR)。在脖子上,19例患者治疗前淋巴结阳性,只有5例患者(26.4%)对区域淋巴结进行了PCR。在14例(73.6%)患者中仍观察到病理阳性淋巴结。与IPR相比,原发性肿瘤窄带成像评估的显着降低与PCR或MPR的可能性更高(92.9%vs.33.3%,P=0.014)。总喉保存率为95.0%。未发现严重的围手术期并发症或围手术期死亡。所有患者均完成推荐的术后放疗/放化疗。中位随访期为12.1个月。1年无进展生存率和总生存率分别为94.1%和92.9%。分别。在后续期间,所有19例接受喉保留手术的患者均保留了喉功能。
    在新辅助化疗中添加免疫检查点抑制剂可有效保留喉功能,而不会增加LAHPC中与手术和术后放疗相关的并发症。
    To evaluate the efficacy and laryngeal function preservation of neoadjuvant treatment with chemotherapy and immune checkpoint inhibitor for locally advanced hypopharyngeal cancer (LAHPC).
    We retrospectively collected LAHPC patients who were diagnosed between February 2022 and June 2023. The patients received a combination of chemotherapy and immune checkpoint inhibitors as the neoadjuvant therapy. The response to treatment, laryngeal function preservation rate, and short-term survival were assessed.
    A total of 20 patients were included. Of these patients, 17 (85.0%) had stage IVA-B disease. Ten (50%) and four (20%) patients achieved pathological complete response (PCR) and major pathological response (MPR) to the primary tumor, respectively. In addition, 6 patients had incomplete pathological response (IPR). In the neck, 19 patients had node-positive disease before treatment, and only 5 patients (26.4%) had PCR to regional lymph nodes. Pathologically positive lymph nodes were still observed in 14 (73.6%) patients. Significant downgrading on narrow-band imaging assessment in primary tumors was associated with a higher probability of PCR or MPR than those with IPR (92.9% vs. 33.3%, P=0.014). The overall rate of laryngeal preservation was 95.0%. No severe perioperative complications or perioperative death were found. All patients completed the recommended postoperative radiotherapy/chemoradiotherapy. The median follow-up period was 12.1 months. The 1-year progression-free survival and overall survival were 94.1% and 92.9%, respectively. During the follow-up period, all 19 patients who underwent laryngeal preservation surgery had their laryngeal function preserved.
    The addition of an immune checkpoint inhibitor to neoadjuvant chemotherapy effectively preserves laryngeal function without increasing complications related to surgery and postoperative radiotherapy in LAHPC.

    背景:在联合治疗时代,对身体成分的研究有限。特定的身体成分,比如肌肉减少症,在接受tislelizumab联合吉西他滨和顺铂(T+GC)治疗的尿路上皮癌(UC)患者中,具有作为毒性作用和临床反应的预测生物标志物的潜力。
    方法:选择2020年4月至2023年1月在徐州医科大学附属医院接受T+GC治疗的UC患者112例。使用电子医疗系统和实验室检查收集基线患者特征和详细血液学参数。分析患者的计算机断层扫描图像以计算腰大肌质量指数(PMI)。我们评估了肌肉减少症(男性PMI<4.5cm2/m2;女性PMI<3.3cm2/m2)与血液学毒性和肿瘤反应之间的关系。
    结果:总体而言,112名患者中(65.2%为男性,中位年龄56岁),43(38.4%)被定义为肌肉减少症。患有肌少症的患者明显年龄较大(p=0.037),更有可能患有高血压(p=0.009),ECOG-PS较差(p=0.027)。在接受至少两个周期的T+GC治疗后,肌肉减少症患者更容易发生白细胞减少症(OR2.969,95%CI1.028-8.575,p=0.044)。然而,在血小板减少症和贫血中未观察到这些显著差异.肌少症患者和无肌少症患者之间的肿瘤反应和3-4级血液学毒性没有显着差异。
    结论:患有肌少症的患者在接受T+GC后更容易出现白细胞减少。没有观察到与贫血或血小板减少有关的显著改变。在肿瘤反应和3-4级血液学毒性方面,肌肉减少组和非肌肉减少组之间没有发现显着差异。
    BACKGROUND: In the era of combination therapy, there has been limited research on body composition. Specific body composition, such as sarcopenia, possesses the potential to serve as a predictive biomarker for toxic effects and clinical response in patients with urothelial carcinoma (UC) undergoing tislelizumab combined with gemcitabine and cisplatin (T + GC).
    METHODS: A total of 112 UC patients who received T + GC were selected at the Affiliated Hospital of Xuzhou Medical University from April 2020 to January 2023. Baseline patient characteristics and detailed hematological parameters were collected using the electronic medical system and laboratory examinations. The computed tomography images of patients were analyzed to calculate psoas muscle mass index (PMI). We evaluated the association between sarcopenia (PMI < 4.5 cm2/m2 in men; PMI < 3.3 cm2/m2 in women) and both hematological toxicity and tumor response.
    RESULTS: Overall, of the 112 patients (65.2% male, median age 56 years), 43 (38.4%) were defined as sarcopenia. Patients with sarcopenia were notably older (p = 0.037), more likely to have hypertension (p = 0.009), and had poorer ECOG-PS (p = 0.027). Patients with sarcopenia were more likely to develop leukopenia (OR 2.969, 95% CI 1.028-8.575, p = 0.044) after receiving at least two cycles of T + GC. However, these significant differences were not observed in thrombocytopenia and anemia. There were no significant differences in the tumor response and grade 3-4 hematological toxicity between patients with sarcopenia and those without sarcopenia.
    CONCLUSIONS: Patients with sarcopenia were more likely to develop leukopenia after receiving T + GC. There were no notable alterations observed in relation to anemia or thrombocytopenia. No significant difference was found between the sarcopenia group and non-sarcopenia group in terms of tumor response and grade 3-4 hematological toxicity.

    背景:淋巴细胞相关因子与不同类型癌症的生存结果相关。然而,淋巴细胞相关因子与免疫治疗的肿瘤应答之间的关联尚不清楚.
    方法:这是一项回顾性研究。符合条件的参与者包括不可切除或晚期肝细胞癌(HCC)的患者,他们接受了免疫治疗作为一线治疗。肿瘤反应的放射学评估符合RECIST1.1和HCC特异性改良RECIST(mRECIST)标准。采用单变量和多变量逻辑分析来分析与肿瘤反应相关的临床因素。采用Kaplan-Meier生存分析来比较不同临床因素的无进展生存(PFS)和总生存(OS)。此外,我们对接受贝伐单抗联合抗PD-1(L1)抗体(Beva组)或酪氨酸激酶抑制剂(TKI)联合抗PD-1抗体(TKI组)治疗的患者进行了检测,以探讨临床因素与肿瘤应答之间的关系.
    结果:本研究共纳入208例患者。中位PFS和OS分别为9.84个月和24.44个月,分别。当PLR<100时,确定了与对免疫疗法更有利的肿瘤反应相关的独立因素。PLR<100的患者比其他患者有更长的PFS,而OS无显著差异。进一步分析显示,与TKI组相比,Beva组患者的PLR具有更好的预后价值。
    结论:在接受免疫治疗的患者中,PLR与肿瘤反应以及生存结果之间存在关联,特别是那些接受贝伐单抗和抗PD-1联合治疗的患者.
    BACKGROUND: Lymphocyte-related factors were associated with survival outcome of different types of cancers. Nevertheless, the association between lymphocytes-related factors and tumor response of immunotherapy remains unclear.
    METHODS: This is a retrospective study. Eligible participants included patients with unresectable or advanced hepatocellular carcinoma (HCC) who underwent immunotherapy as their first-line treatment. Radiological assessment of tumor response adhered to RECIST 1.1 and HCC-specific modified RECIST (mRECIST) criteria. Univariate and multivariate logistic analyses were employed to analyze clinical factors associated with tumor response. Kaplan-Meier survivial analysis were employed to compare progression-free survival (PFS) and overall survival (OS) across different clinical factors. Furthermore, patients who received treatment with either a combination of bevacizumab and anti-PD-1(L1) antibody (Beva group) or tyrosine-kinase inhibitor (TKI) and anti-PD-1 antibody (TKI group) were examined to explore the relation between clinical factors and tumor response.
    RESULTS: A total of 208 patients were enrolled in this study. The median PFS and OS were 9.84 months and 24.44 months,respectively. An independent factor associated with a more favorable tumor response to immunotherapy was identified when PLR<100. Patients with PLR<100 had longer PFS than other patients, while OS showed no significant difference. Further analysis revealed that PLR exhibited superior prognostic value in patients of the Beva group as compared to those in the TKI group.
    CONCLUSIONS: There exisits an association between PLR and tumor response as well as survival outcomes in patients receiving immunotherapy, particularly those treated with the combination of bevacizumab and anti-PD-1.

    新辅助放化疗已成为局部晚期直肠癌的既定治疗方法。然而,对于在新辅助放化疗和手术后表现出良好肿瘤反应(ypT0-2N0)的局部晚期直肠癌患者,是否需要辅助化疗仍存在争议.因此,本研究的目的是探讨对新辅助放化疗反应良好的直肠癌患者,辅助化疗对肿瘤预后的影响。
    本研究按照系统评价和荟萃分析方案的首选报告项目进行。文章在WebofScience上搜索,PubMed,和Cochrane图书馆数据库。评估的主要结果是5年总生存率,无病生存,癌症特异性生存率,无复发生存率,局部复发,和远处转移。使用随机效应模型总结数据。
    使用2009年至2023年之间发表的18项回顾性研究进行了荟萃分析。这些研究包括9项来自中国和5项来自韩国,共有6566例接受新辅助放化疗后的ypT0-2N0直肠癌患者。汇总数据显示,辅助化疗显著改善5年总生存率(OR=1.75,95%CI:1.15-2.65,P=0.008)。无复发生存率(OR=1.73,95%CI:1.20-2.48,P=0.003),远处转移减少(OR=0.68,95%CI:0.51-0.92,P=0.011)。然而,辅助化疗对无病生存率没有显著影响,癌症特异性生存率,ypT0-2N0直肠癌的局部复发。亚组分析表明,辅助化疗有利于改善ypT1-2N0直肠癌的总生存期(OR=1.89,95%CI:1.13-3.19,P=0.003)。
    荟萃分析的结果表明,在新辅助放化疗和根治性手术后,apT0-2N0的直肠癌患者的肿瘤预后方面,辅助化疗可能会带来益处。然而,需要进一步的前瞻性临床研究来证实这些发现.
    UNASSIGNED: Neoadjuvant chemoradiotherapy has emerged as the established treatment for locally advanced rectal cancer. Nevertheless, there remains a debate regarding the necessity of adjuvant chemotherapy for patients with locally advanced rectal cancer who exhibit a favorable tumor response (ypT0-2N0) after neoadjuvant chemoradiotherapy and surgery. Thus, the objective of this study is to investigate the impact of adjuvant chemotherapy on the oncological prognosis of rectal cancer patients who have a good response to neoadjuvant chemoradiotherapy.
    UNASSIGNED: The study was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol. Articles were searched in the Web of Science, PubMed, and Cochrane Library databases. The primary outcomes assessed were 5-year overall survival, disease-free survival, cancer-specific survival, recurrence-free survival, local recurrence, and distant metastasis. The data was summarized using a random effects model.
    UNASSIGNED: A meta-analysis was conducted using 18 retrospective studies published between 2009 and 2023. The studies included 9 from China and 5 from Korea, involving a total of 6566 patients with ypT0-2N0 rectal cancer after neoadjuvant chemoradiotherapy. The pooled data revealed that adjuvant chemotherapy significantly improved 5-year overall survival (OR=1.75, 95% CI: 1.15-2.65, P=0.008), recurrence-free survival (OR=1.73, 95% CI: 1.20-2.48, P=0.003), and reduced distant metastasis (OR=0.68, 95% CI: 0.51-0.92, P=0.011). However, adjuvant chemotherapy did not have a significant effect on disease-free survival, cancer-specific survival, and local recurrence in ypT0-2N0 rectal cancer. Subgroup analysis indicated that adjuvant chemotherapy was beneficial in improving overall survival for ypT1-2N0 rectal cancer (OR=1.89, 95% CI: 1.13-3.19, P=0.003).
    UNASSIGNED: The findings of the meta-analysis suggest that adjuvant chemotherapy may provide benefits in terms of oncological outcomes for rectal cancer patients with ypT0-2N0 after neoadjuvant chemoradiotherapy and radical surgery. However, further prospective clinical studies are needed to confirm these findings.

    背景:最近,在肝细胞癌(HCC)患者中,联合治疗在改善肿瘤反应和生存结局方面的趋势优于单药治疗.然而,关于三联疗法[lenvatinib+sintilimab+经肝动脉化疗栓塞(TACE)]作为晚期HCC一线治疗的研究有限.
    目的:评价三联疗法作为晚期肝癌一线治疗的安全性和有效性。
    方法:纳入接受三联疗法治疗的巴塞罗那临床肝癌C期肝癌患者。所有患者每天接受lenvatinib治疗,每3周接受一次sintilimab治疗。此外,必要时每4-6周进行一次TACE。该研究的主要结果是总生存期(OS)。次要结果是客观反应率(ORR),疾病控制率(DCR),和不良事件的发生率。
    结果:从2019年1月至2022年1月,对40例接受三联疗法的HCC患者进行了回顾性分析。中位随访时间为8.5个月,3-,6-,12个月的操作系统率为100%,88.5%,和22.5%,分别。ORR和DCR分别为45%和90%,分别。未达到中位无进展生存期和中位OS。在76%的患者中观察到常见的并发症(3级,15%;4级,2.5%)。
    结论:联合治疗包括lenvatinib,sintilimab和TACE在晚期HCC患者中取得了有希望的结果,并且效果可控。
    BACKGROUND: Recently, combination therapy has shown a better trend towards improved tumour response and survival outcomes than monotherapy in patients with hepatocellular carcinoma (HCC). However, research on triple therapy [lenvatinib + sintilimab + transarterial chemoembolization (TACE)] as a first-line treatment for advanced HCC is limited.
    OBJECTIVE: To evaluate the safety and efficacy of triple therapy as a first-line treatment for advanced HCC.
    METHODS: HCC patients with Barcelona Clinic Liver Cancer stage C treated with triple therapy were enrolled. All patients were treated with lenvatinib every day and sintilimab once every 3 wk. Moreover, TACE was performed every 4-6 wk if necessary. The primary outcome of the study was overall survival (OS). The secondary outcomes were the objective response rate (ORR), disease control rate (DCR), and incidence of adverse events.
    RESULTS: Forty HCC patients who underwent triple therapy were retrospectively analysed from January 2019 to January 2022. With a median follow-up of 8.5 months, the 3-, 6-, and 12-mo OS rates were 100%, 88.5%, and 22.5%, respectively. The ORR and DCR were 45% and 90%, respectively. The median progressive free survival and median OS were not reached. Common complications were observed in 76% of the patients (grade 3, 15%; grade 4, 2.5%).
    CONCLUSIONS: Combination therapy comprising lenvatinib, sintilimab and TACE achieved promising outcomes in advanced HCC patients and had manageable effects.

    背景:研究表明,关于原发性肿瘤体积(TV)和转移性淋巴结(NV)体积在局部晚期头颈部鳞状细胞癌(LAHNSCC)确定性放疗疗效中的作用。
    目的:我们旨在评估TV和NV对LAHNSCC患者根治性放疗疗效的影响,以指导个体化治疗为目标。
    方法:选择2012年1月至2021年12月接受根治性放射治疗并在治疗后6个月内复查的LAHNSCC患者。通过软件计算原发肿瘤和转移淋巴结的体积,然后根据与中位数的关系将其分为大电视组vs小电视组和大NV组vs小NV组。此外,接受或未接受同步放化疗(CCRT)的患者分为CCRT组和放疗(RT)组.淋巴结转移患者根据是否接受同步化疗分为淋巴结同步化疗(N-CCRT)组和淋巴结转移化疗(N-RT)组。体积收缩率(VSR),客观反应率(ORR),记录并分析局部控制率(LCR)和总生存期(OS).
    结果:96例患者被纳入原发肿瘤体积组,淋巴结转移组包括73例患者。为客观缓解(OR)终点构建受试者工作特征(ROC)曲线,并为TV和NV患者定义容量阈值.阈值原发肿瘤体积为32.45cm3,阈值转移淋巴结体积为6.05cm3。小型电视和大型电视集团的初级电视收缩率基本一致,P=0.801。同样,小电视组和大电视组之间的ORR和LCR没有显着差异(PORR=0.118,PLCR=0.315)。此外,CCRT组与RT组之间的TV收缩率没有显着差异,P=0.133。此外,CCRT组ORR和LCR差异无统计学意义(PORR=0.057,PLCR=0.088)。然而,小NV组转移淋巴结体积收缩率明显大于大NV组(P=0.001)。小NV亚组的ORR和LCR显著大于大NV亚组(PORR=0.002,PLCR=0.037)。此外,与N-RT组相比,N-CCRT组的NV收缩率为84.10±s3.11%,收缩率为70.76±s5.77%(P=0.047)。对于ORR和LCR,N-CCRT组与N-RT组差异有统计学意义(PORR=0.030,PLCR=0.037)。全组中位OS为26个月。然而,TV/NV或同步化疗似乎都不影响OS。
    结论:原发性肿瘤体积不是LAHNSCC患者放疗疗效的预后因素。然而,转移淋巴结是影响LAHNSCC患者放疗疗效的预后因素。淋巴结较小的患者具有更好的局部控制。
    BACKGROUND: Studies have shown mixed results concerning the role of primary tumor volume (TV) and metastatic lymph node (NV) volume in response to the curative effect of definitive radiotherapy for locally advanced head and neck squamous cell carcinoma (LAHNSCC).
    OBJECTIVE: We aimed to evaluate the impact of TV and NV on the efficacy of radical radiotherapy in LAHNSCC patients, with the goal of guiding individualized therapy.
    METHODS: Patients with LAHNSCC who received radical radiation therapy and were reexamined within 6 months post-therapy from January 2012 to December 2021 were selected. The volumes of the primary tumors and metastatic lymph nodes were calculated by software and then were divided into a large TV group vs small TV group and a large NV group vs small NV group according to the relationship with the median. Additionally, patients who received concurrent chemoradiotherapy (CCRT) or not were divided into the CCRT group and the radiotherapy (RT) group. Patients with lymph node metastasis were divided into node concurrent chemotherapy (N-CCRT) group and a node metastatic chemotherapy (N-RT) group according to whether they received concurrent chemotherapy or not. The volume shrinkage rate (VSR), objective response rate (ORR), local control rate (LCR) and overall survival (OS) were recorded and analyzed.
    RESULTS: 96 patients were included in the primary tumor volume group, and 73 patients were included in the metastatic lymph node group. Receiver operating characteristic (ROC) curves were constructed for objective remission (OR) endpoints, and a volume threshold was defined for TV and NV patients. The threshold primary tumor volume was 32.45 cm3, and the threshold metastatic lymph node volume was 6.05 cm3.The primary TV shrinkage rates of the small TV and the large TV groups were basically the same, P = 0.801. Similarly, the ORR and LCR were not significantly different between the small TV group and the large TV group (PORR = 0.118, PLCR = 0.315). Additionally, the TV shrinkage rate did not significantly differ between the CCRT group and the RT group, P = 0.133. Additionally, there was no significant difference in ORR or LCR in CCRT group (PORR = 0.057, PLCR = 0.088). However, the metastatic lymph node volume shrinkage rate in the small NV group was significantly greater than that in the large NV group (P = 0.001). The ORR and LCR of the small NV subgroup were significantly greater than those of the large NV subgroup (PORR = 0.002, PLCR = 0.037). Moreover, compared with that of the N-RT group, the NV shrinkage rate of the N-CCRT group was 84.10 ± s3.11%, and the shrinkage rate was 70.76 ± s5.77% (P = 0.047). For the ORR and LCR, the N-CCRT group and N-RT group were significantly different (PORR = 0.030, PLCR = 0.037). The median OS of the whole group was 26 months. However, neither TV/NV nor concurrent chemotherapy seemed to influence OS.
    CONCLUSIONS: Primary tumor volume is not a prognostic factor for the response to curative effect radiotherapy in LAHNSCC patients. Nevertheless, metastatic lymph nodes are a prognostic factor for the response to curative effect radiotherapy in LAHNSCC patients. Patients with smaller lymph nodes have better local control.

    免疫治疗已显示出脑转移非小细胞肺癌(NSCLC)患者的颅内疗效。然而,缺乏免疫疗法颅内反应的预测性生物标志物.这项事后分析旨在探索脑脊液(CSF)中免疫细胞因子预测脑转移患者颅内肿瘤对免疫治疗反应的潜力。
    纳入接受卡姆瑞珠单抗联合化疗的未治疗脑转移NSCLC患者。在基线和第一次治疗评估时前瞻性地收集配对的血浆和CSF样品。使用Olink小组分析所有样品的92种免疫肿瘤学细胞因子。
    本分析共纳入28例患者。在基线,大多数免疫细胞因子在CSF中显著低于血浆,而包含CD83、PTN、TNFRSF21,TWEAK,ICOSLG,DCN,IL-8和MCP-1在CSF中增加。有颅内肿瘤反应的患者的基线CSF水平显著较高,而CXCL10,IL-12,CXCL11,IL-18,TIE2,HGF的水平,和PDCD1显著降低。此外,CXCL10,CXCL11,TIE2,PDCD1,IL-18,HGF,CSF中的LAMP3也与免疫治疗的颅内无进展生存期显著相关.在具有颅内肿瘤反应的患者中,首次治疗评估时,CSF中鉴定的细胞因子降低。与PD-L1表达(AUC为0.72)相比,逻辑CSF免疫细胞因子模型产生0.91的AUC。
    CSF中的免疫细胞因子可以预测伴有脑转移的NSCLC患者对免疫疗法的颅内肿瘤反应,这些发现值得在更大的前瞻性队列研究中验证。

    UNASSIGNED: Immunotherapy has shown intracranial efficacy in non-small cell lung cancer (NSCLC) patients with brain metastases. However, predictive biomarkers for intracranial response to immunotherapy are lacking. This post-hoc analysis aimed to explore the potential of immunological cytokines in cerebrospinal fluid (CSF) to predict intracranial tumor response to immunotherapy in patients with brain metastases.
    UNASSIGNED: Treatment-naive NSCLC patients with brain metastases who received camrelizumab plus chemotherapy were enrolled. Paired plasma and CSF samples were prospectively collected at baseline and the first treatment assessment. All samples were analyzed for 92 immuno-oncology cytokines using Olink\'s panels.
    UNASSIGNED: A total of 28 patients were included in this analysis. At baseline, most immunological cytokines were significantly lower in CSF than in plasma, whereas a subset comprising CD83, PTN, TNFRSF21, TWEAK, ICOSLG, DCN, IL-8, and MCP-1, was increased in CSF. Baseline CSF levels of LAMP3 were significantly higher in patients with intracranial tumor response, while the levels of CXCL10, IL-12, CXCL11, IL-18, TIE2, HGF, and PDCD1 were significantly lower. Furthermore, the CXCL10, CXCL11, TIE2, PDCD1, IL-18, HGF, and LAMP3 in CSF were also significantly associated with intracranial progression-free survival for immunotherapy. The identified cytokines in CSF were decreased at the first treatment evaluation in patients with intracranial tumor response. The logistic CSF immuno-cytokine model yielded an AUC of 0.91, as compared to PD-L1 expression (AUC of 0.72).
    UNASSIGNED: Immunological cytokines in CSF could predict intracranial tumor response to immunotherapy in NSCLC patients with brain metastases, and the findings warrant validation in a larger prospective cohort study.

    目的:这里描述的工作的目的是探索超声造影(CEUS)定量参数在预测联合免疫检查点抑制剂(ICI)和抗血管生成疗法对不可切除的肝细胞癌(HCC)的反应中的价值。
    方法:前瞻性招募了66名接受ICI和抗血管生成联合治疗的HCC患者。基线时进行CEUS检查,用灌注定量软件获得肿瘤灌注参数。比较应答者和非应答者之间CEUS定量参数的差异,评估CEUS参数与无进展生存期(PFS)之间的相关性.
    结果:客观缓解率(ORR)为21.2%。上升时间(RT)比率的值,时间峰值比,下降时间比,峰值增强比,洗入率比,洗入灌注指数比率和洗出率比率在响应者和无响应者组之间存在显着差异(所有p值<0.05)。多变量logistic回归分析显示,RT比率是与ORR相关的唯一独立因素(比值比=0.007,95%置信区间:0.000-0.307,p=0.010)。应答者和非应答者组的中位RT比率分别为36.9和58.9(p=0.006)。RT比率的适当截止点是80.1,用X-tile程序确定。生存分析显示RT比率较低的患者具有较高的PFS(高RT比率与低RT比率=4.4movs.没有到达,p=0.001)。
    结论:CEUS定量参数可以预测ICI和抗血管生成联合治疗HCC的疗效。
    The aim of the work described here was to explore the value of contrast-enhanced ultrasound (CEUS) quantitative parameters in predicting the response of combined immune checkpoint inhibitor (ICI) and anti-angiogenesis therapies for unresectable hepatocellular carcinoma (HCC).
    Sixty-six HCC patients who underwent combined ICI and anti-angiogenesis therapies were prospectively enrolled. A CEUS examination was performed at baseline, and tumor perfusion parameters were obtained with perfusion quantification software. The differences in CEUS quantitative parameters between the responder and non-responder groups were compared, and the correlations between CEUS parameters and progression-free survival (PFS) was evaluated.
    The objective response rate (ORR) was 21.2%. The values of rising time (RT) ratio, time to peak ratio, fall time ratio, peak enhancement ratio, wash-in rate ratio, wash-in perfusion index ratio and wash-out rate ratio differed significantly differed between the responder and non-responder groups (all p values < 0.05). Multivariable logistic regression analysis revealed that the RT ratio was the only independent factor associated with the ORR (odds ratio = 0.007, 95% confidence interval: 0.000-0.307, p = 0.010). The median RT ratios of the responder and non-responder groups were 36.9 and 58.9, respectively (p = 0.006). The appropriate cutoff point of the RT ratio was 80.1, determined with the X-tile program. Survival analysis indicated high PFS for the patients with a lower RT ratio (high RT ratio vs. low RT ratio = 4.4 mo vs. not reached, p = 0.001).
    CEUS quantitative parameters may predict the efficacy of ICI and anti-angiogenesis combined therapies for HCC.
