Early relapse

早期复发
  • 文章类型: Journal Article
    基因组不稳定性是肿瘤发生和血液系统恶性肿瘤发展的主要驱动因素之一。癌细胞可以通过上调DNA修复基因并最终诱导治疗抗性来修复化疗诱导的DNA损伤。然而,DNA修复基因之间的关联,耐药性,在急性淋巴细胞白血病(ALL)中,疾病复发尚未得到很好的表征。这项研究旨在探讨DNA修复机制的作用及其在早期和晚期复发的小儿ALL患者中受到调节的分子机制。我们对198例复发性儿科前体B细胞ALL的治疗适用研究(TARGET)-ALL扩展II期试验进行了二次数据分析。在这项研究中,对147个DNA修复基因进行了全面的遗传和表观遗传调查。使用微阵列和RNA测序平台评估基因表达。基因组交替,甲基化状态,和miRNA转录组研究了候选DNA修复基因。我们确定了三个DNA修复基因,ALKBH3、NHEJ1和PARP1与晚期复发者相比在早期复发者中上调(p<0.05)。这种在诊断时的上调与前体B-ALL的无病生存率和总生存率显著相关(p<0.05)。此外,PARP1上调伴随着其靶向miRNA的显著下调,miR-1301-3p(p=0.0152),这与较差的无病生存率和总体生存率密切相关。DNA修复基因的上调,特别是PARP1,增加儿童前体B-ALL早期复发的可能性。PARP1在早期复发者中相对于晚期复发者上调的观察结果可能是提出替代治疗方法的有效理由。例如在化疗中使用PARP抑制剂。
    Genomic instability is one of the main drivers of tumorigenesis and the development of hematological malignancies. Cancer cells can remedy chemotherapeutic-induced DNA damage by upregulating DNA-repair genes and ultimately inducing therapy resistance. Nevertheless, the association between the DNA-repair genes, drug resistance, and disease relapse has not been well characterized in acute lymphoblastic leukemia (ALL). This study aimed to explore the role of the DNA-repair machinery and the molecular mechanisms by which it is regulated in early- and late-relapsing pediatric ALL patients. We performed secondary data analysis on the Therapeutically Applicable Research to Generate Effective Treatments (TARGET)-ALL expansion phase II trial of 198 relapsed pediatric precursor B-cell ALL. Comprehensive genetic and epigenetic investigations of 147 DNA-repair genes were conducted in the study. Gene expression was assessed using Microarray and RNA-sequencing platforms. Genomic alternations, methylation status, and miRNA transcriptome were investigated for the candidate DNA-repair genes. We identified three DNA-repair genes, ALKBH3, NHEJ1, and PARP1, that were upregulated in early relapsers compared to late relapsers (p < 0.05). Such upregulation at diagnosis was significantly associated with disease-free survival and overall survival in precursor-B-ALL (p < 0.05). Moreover, PARP1 upregulation accompanied a significant downregulation of its targeting miRNA, miR-1301-3p (p = 0.0152), which was strongly linked with poorer disease-free and overall survivals. Upregulation of DNA-repair genes, PARP1 in particular, increases the likelihood of early relapse of precursor-B-ALL in children. The observation that PARP1 was upregulated in early relapsers relative to late relapsers might serve as a valid rationale for proposing alternative treatment approaches, such as using PARP inhibitors with chemotherapy.

    弥漫性大B细胞淋巴瘤(DLBCL)表现出显著的异质性,中国维吾尔族和汉族DLBCL患者在临床和分子特征上的差异仍未被研究。我们回顾性分析了279例DLBCL患者(维吾尔族105例,汉族174例),其中155例患者接受了NGS的遗传分析。与汉族患者相比,维吾尔族患者有较好的临床预后指标,包括较高比例的0-1结外受累和I/IIAnnArbor分期的患者。始终如一,维吾尔族患者复发风险较低(P=0.06),与汉族患者相比,一年复发率为5%vs17%,两年复发率为19%vs36%。在分子水平上,TP53(21.3%)是该队列中最频繁改变的基因之一。值得注意的是,维吾尔族患者TP53改变的频率明显较低,ASXL3改变的频率较高.Logistic回归分析显示,维吾尔族患者TP53的频率降低和ASXL3的富集与其他因素无关。然而,只有TP53突变患者的复发率高于TP53野生型患者(一年,20%vs10%;两年期,51%vs21%)。我们的发现强调了维吾尔族患者TP53突变频率低的显着贡献,这是与该人群预后良好相关的关键因素。
    Diffuse large B-cell lymphoma (DLBCL) demonstrates significant heterogeneity, investigations into the distinctions in clinical and molecular characteristics between Chinese Uygur and Han DLBCL patients remain unexplored. We retrospectively reviewed 279 DLBCL patients (105 Uygur and 174 Han patients), of which 155 patients underwent genetic profiling by NGS. Compared with Han patient, Uygur patients have better clinical prognostic indicators, including a higher proportion of patients with 0-1 extranodal involvement and I/II Ann Arbor staging. Consistently, Uygur patients were significantly associated with lower risk of relapse (P = 0.06), with a one-year relapse rate of 5% vs 17% and two-year relapse rate of 19% vs 36% compared to Han patients. At the molecular level, TP53 (21.3%) was among the top frequently altered gene in the cohort. Notably, the Uygur patients exhibited a significantly lower frequency of TP53 alterations and higher frequency of ASXL3 alterations. Logistic regression analysis showed that the lowered frequency of TP53 and enrichment of ASXL3 in the Uygur patients were independent of other factors. However, only patients with TP53 mutations had higher relapse rate than those with wild type TP53 (one-year, 20% vs 10%; two-year, 51% vs 21%). Our findings highlight the notable contribution of a low TP53 mutation frequency in Uygur patients as a pivotal factor associated with the favorable prognosis of this population.

    一部分多发性骨髓瘤(MM)患者早期复发或对一线治疗无反应。识别这些患者的可能的临床和/或生物学特征仍然是未满足的医疗需求。在这项研究中,我们评估了早期复发MM的预测标志物,定义为在18个月内发生的进行性疾病,来自没有原发性难治性疾病的MM患者的自体干细胞移植(ASCT)。74名连续的MM患者被纳入接受ASCT强化治疗的研究。该研究能够确定符合ASCT的新诊断ERMM患者的主要特征,鉴定IgA同种型和R2-ISS评分系统作为该MM患者队列中ER的主要预测预后因素。
    A portion of multiple myeloma (MM) patients relapse early or do not respond to first line treatment. Identification of possible clinical and or biological features of these patients remains an unmet medical need. In this study we assesed the predictive markers for early relapse MM, defined as a progressive disease that occurred within 18 months, from autologoust stem cell transplantation (ASCT) in MM patients who did not have primary refractory disease. 74 consecutive MM patients were included in the study that received intensive therapy with ASCT. The study was able to identify the main features of newly diagnosed ER MM patients eligible for ASCT identifying the IgA isotype and the R2-ISS score system as the main predictive prognostic factors for ER in this cohort of MM patients.

    难治性或复发性(R/R)大B细胞淋巴瘤(LBCL)一线化疗难治或早期复发的患者预后较差。虽然嵌合抗原受体(CAR)T细胞疗法在两种或多种化疗方案后具有令人印象深刻的疗效,在三线CAR-T细胞治疗的背景下,这些结果是否保持一致仍不确定.我们对107例R/RLBCL患者进行了回顾性研究。一线化疗后12个月或更长时间复发的患者(晚期失败:n=25)的总生存期(OS)明显长于难治性疾病或12个月内复发的患者(早期失败:n=82)(中位OS:未达到vs.18.4个月;P<0.001)。在进行自体造血干细胞移植(auto-HSCT)的患者中,晚期失败患者的无事件生存期(EFS)明显长于早期失败患者(中位EFS:26.9vs.3.1个月;P=0.012)。然而,在接受CAR-T细胞治疗的患者中,EFS没有检测到显著差异(EFS中位数:未达到vs.11.8;P=0.091)。限制性三次样条的Cox回归表明,复发时间对自动HSCT患者的EFS有显著影响,但对CART细胞治疗患者没有影响。在计划接受CAR-T细胞治疗的患者中,与早期失败的患者相比,晚期失败的患者接受CART细胞治疗的可能性明显更高(90%vs.57%;P=0.008)。总之,在批准三线CAR-T细胞治疗后,早期失败患者的结局仍然较差.
    Patients with refractory or relapsed (R/R) large B-cell lymphoma (LBCL) refractory to first-line chemotherapy or with early relapse have poor outcomes. While chimeric antigen receptor (CAR) T-cell therapy has impressive efficacy after two or more lines of chemotherapy, it\'s still uncertain if these outcomes remain consistent in the context of third-line CAR T-cell therapy. We conducted a retrospective study of 107 R/R LBCL patients. Patients with relapse 12 months or more after their first-line chemoimmunotherapy (late failure: n = 25) had significantly longer overall survival (OS) than patients with refractory disease or relapse within 12 months (early failure: n = 82) (median OS: not achieved vs. 18.4 months; P < 0.001). Among patients who proceeded to autologous hematopoietic stem-cell transplantation (auto-HSCT), those with late failure had significantly longer event-free survival (EFS) than those with early failure (median EFS: 26.9 vs. 3.1 months; P = 0.012). However, no significant difference in EFS was detected among patients who underwent CAR T-cell therapy (median EFS: not reached vs. 11.8; P = 0.091). Cox regression with restricted cubic spline demonstrated that timing of relapse had significant impact on EFS in patients with auto-HSCT but not in patients with CAR T-cell therapy. Of patients who were scheduled for CAR T-cell therapy, those with late failure were significantly more likely to receive CAR T-cell therapy than those with early failure (90% vs. 57%; P = 0.008). In conclusion, patients with early failure still experienced poor outcomes after the approval of third-line CAR T-cell therapy.

    探讨接受新辅助化疗的局部晚期乳腺癌(LABC)患者血脂比值与生存结果之间的关系。
    这项回顾性研究包括接受新辅助化疗的LABC患者。在基线时前瞻性地测量血清脂质水平。甘油三酯与总胆固醇(TG/TC)的关系,评估甘油三酯与高密度脂蛋白(TG/HDL)和甘油三酯与低密度脂蛋白(TG/LDL)的比值与预后的关系。
    高TG/TC患者(调整后的危险比[aHR]=2.47,95%CI:1.10,5.56,p=0.029),TG/HDL(aHR=2.73,95%CI:1.16,6.41,p=0.021)和TG/LDL(aHR=2.50,95%CI:1.11,5.65,p=0.027)比率更可能出现无病生存(DFS)事件。亚组分析表明,在HER2状态阴性或复发风险较高的患者中,血脂比率对预后的影响更为明显(例如,临床III期,Ki67>30%)。此外,较高的脂质比率往往表明早期DFS事件(0〜2年)(TG/TCp=0.021,TG/HDLp=0.046,TG/LDLp<0.001),TG/LDL比率显示出最佳的预测功效(TG/TCvs.TG/HDL与TG/LDL,1年AUC:0.724vs.0.676vs.0.846,2年AUC:0.653vs.0.638vs.0.708)。
    基线血清TG/TC,TG/HDL和TG/LDL比值是接受新辅助治疗的LABC患者的独立预后因素。然而,它们在预测早期DFS事件中的效用值得进一步调查。

    UNASSIGNED: To investigate the association between lipid ratios and survival outcomes in patients with locally advanced breast cancer (LABC) undergoing neoadjuvant chemotherapy.
    UNASSIGNED: This retrospective study included patients with LABC receiving neoadjuvant chemotherapy. Serum lipid levels were prospectively measured at baseline. Associations of triglyceride to total cholesterol (TG/TC), triglyceride to high-density lipoprotein (TG/HDL) and triglyceride to low-density lipoprotein (TG/LDL) ratios with prognosis were evaluated.
    UNASSIGNED: Patients with high TG/TC (adjusted hazard ratio [aHR] = 2.47, 95% CI: 1.10, 5.56, p = 0.029), TG/HDL (aHR = 2.73, 95% CI: 1.16, 6.41, p = 0.021) and TG/LDL (aHR = 2.50, 95% CI: 1.11, 5.65, p = 0.027) ratios were more likely to experience disease-free survival (DFS) events. Subgroup analysis suggested that the prognostic impact of lipid ratios was more pronounced in patients with negative HER2 status or those at a high risk of recurrence (e.g. clinical stage III, Ki67 > 30%). Additionally, higher lipid ratios tended to indicate early DFS events (0 ~ 2 years) (TG/TC p = 0.021, TG/HDL p = 0.046, TG/LDL p < 0.001), and the TG/LDL ratio demonstrated the best predictive efficacy (TG/TC vs. TG/HDL vs. TG/LDL, 1-year AUC: 0.724 vs. 0.676 vs. 0.846, 2-year AUC: 0.653 vs. 0.638 vs. 0.708).
    UNASSIGNED: Baseline serum TG/TC, TG/HDL and TG/LDL ratios were independent prognostic factors in patients with LABC undergoing neoadjuvant therapy. However, their utility in predicting the early DFS events warrants further investigation.
    UNASSIGNED: NCT05621564.

    背景:肝切除术后早期复发对肝细胞癌(HCC)的治疗提出了重大挑战。这项研究的目的是建立和验证一种新的列线图模型,用于预测肝癌肝切除术后的早期复发和生存率。
    方法:我们进行了大规模,来自4个医疗中心的1,505例经手术治疗的HCC患者的多中心回顾性分析。所有患者以7:3的比例随机分为训练组(n=1,053)或验证组(n=452)。通过整合影响早期复发和生存的多个危险因素,建立了基于机器学习的HCC预测模型。这些数据是从患者的术前临床数据和术后病理特征中确定的。
    结果:早期复发的中位时间为7个月,而从早期复发到死亡的中位时间仅为19个月.术后列线图预测无病生存期和总生存期的一致性指数分别为0.741和0.739,校准良好的曲线表明预测结果和观察结果之间具有良好的一致性。此外,术后列线图的准确性和预测性能显著优于术前列线图和其他7个HCC分期系统.模型中高危组患者早期和危重复发的概率明显较高(P<.001),而低危组患者晚期复发和局部复发的概率较高(P<.001).
    结论:该术后列线图模型可以更好地预测早期复发和生存率,可以作为指导HCC患者临床治疗决策的有用工具。
    Early relapse after hepatectomy presents a significant challenge in the treatment of hepatocellular carcinoma (HCC). The aim of this study was to construct and validate a novel nomogram model for predicting early relapse and survival after hepatectomy for HCC.
    We conducted a large-scale, multicenter retrospective analysis of 1,505 patients with surgically treated HCC from 4 medical centers. All patients were randomly divided into either the training cohort (n=1,053) or the validation cohort (n=452) in a 7:3 ratio. A machine learning-based nomogram model for prediction of HCC was established by integrating multiple risk factors that influence early relapse and survival, which were identified from preoperative clinical data and postoperative pathologic characteristics of the patients.
    The median time to early relapse was 7 months, whereas the median time from early relapse to death was only 19 months. The concordance indexes of the postoperative nomogram for predicting disease-free survival and overall survival were 0.741 and 0.739, respectively, with well-calibrated curves demonstrating good consistency between predicted and observed outcomes. Moreover, the accuracy and predictive performance of the postoperative nomograms were significantly superior to those of the preoperative nomogram and the other 7 HCC staging systems. The patients in the intermediate- and high-risk groups of the model had significantly higher probabilities of early and critical recurrence (P<.001), whereas those in the low-risk group had higher probabilities of late and local recurrence (P<.001).
    This postoperative nomogram model can better predict early recurrence and survival and can serve as a useful tool to guide clinical treatment decisions for patients with HCC.

    目的:我们回顾了抗CD19嵌合抗原受体(CAR)T细胞疗法在大B细胞淋巴瘤(LBCL)中的最新实践改变试验,包括与二线标准治疗(SOC)的3期比较和在移植不合格患者或作为一线治疗的一部分的2期研究。
    结果:ZUMA-7发现使用axicabtageneciloleucel(axi-cel)的总生存率和无事件生存率(EFS)与抢救化疗后自体干细胞移植的SOC相比,显着提高。这代表了近30年来早期复发或难治性(r/r)LBCL的首次此类生存改善。TRANSFORM显示,与SOC相比,Lisocabtagenemaraleucel(liso-cel)的EFS延长,但BELINDA的Tisagenlecleucel没有延长。二线CART细胞是老年人(ZUMA-7;axi-cel)和/或移植不合格(PILOT;liso-cel)患者的可行治愈性治疗。ZUMA-12证明了axi-cel作为高风险LBCL一线治疗的一部分的有效性。这些结果支持了CART细胞疗法作为r/rLBCL的新二线SOC的作用,并强调了其未来高风险疾病一线治疗的潜在演变。
    We review the recent practice-changing trials of anti-CD19 chimeric antigen receptor (CAR) T cell therapies in large B cell lymphoma (LBCL) including phase 3 comparisons with second-line standard-of-care (SOC) and phase 2 investigations in transplant-ineligible patients or as part of first-line treatment.
    ZUMA-7 found significantly improved overall survival and event-free survival (EFS) with axicabtagene ciloleucel (axi-cel) versus SOC of salvage chemotherapy followed by autologous stem-cell transplantation. This represents the first such survival improvement in nearly 30 years for early-relapsed or refractory (r/r) LBCL. TRANSFORM demonstrated prolonged EFS for lisocabtagene maraleucel (liso-cel) versus SOC but BELINDA did not for tisagenlecleucel. Second-line CAR T cell was a viable curative-intent therapy in elderly (ZUMA-7; axi-cel) and/or transplant-ineligible (PILOT; liso-cel) patients. ZUMA-12 demonstrated effectiveness for axi-cel as part of first-line treatment for high-risk LBCL. These results support a role for CAR T cell therapy as new second-line SOC for r/r LBCL and highlight its potential evolution into future first-line treatment for high-risk disease.

    背景:对治疗的反应持续时间是主要的预后因素,早期复发(ER)强烈预测多发性骨髓瘤(MM)的生存率较低。然而,MM中ER的定义因研究而异,如何动态整合风险分布仍未解决。
    方法:本研究评估了这些ER定义,并进一步调查了来自中国国家血液病纵向队列(NCT04645199)的629例新诊断MM(NDMM)患者的静态风险分布的潜在关系。
    结果:这些数据表明,初始治疗后18个月内的早期复发(ER18)是识别MMs早期进展和动态高风险的最佳时间点。与参考队列相比,ER18人群(587人中的114人,19.4%)表现出更具侵略性的生物学特征和对治疗的反应较差(p<.001),中位总生存期(OS)为28.9个月。多变量分析证实,在国际分期系统阶段的背景下,ER18对OS的最重要预后价值,乳酸脱氢酶升高,血小板减少症,细胞遗传学异常,和治疗(危险比,4.467;p<.001)。作者还描述了从静态风险状况到动态风险分布的具体转变,然后构建了一个混合风险模式来识别四个具有不同存活率的新人群(p<.001)。此外,作者提出了一种预测动态风险变化的第二状态模型,在促进个性化系统治疗方面,能够对修订后的国际分期系统模式起到补充作用。
    结论:总的来说,本研究的结论是,ER18是MM中一种简单且动态的预后预测因子.除了静态风险评估,动态风险在生存预测中起着重要作用。
    The duration of response to treatment is a major prognostic factor, and early relapse (ER) strongly predicts inferior survival in multiple myeloma (MM). However, the definitions of ER in MM vary from study to study and how to dynamically integrate risk distribution is still unsolved.
    This study evaluated these ER definitions and further investigated the underlying relationship with static risk distribution in 629 newly diagnosed MM (NDMM) patients from the National Longitudinal Cohort of Hematological Diseases in China (NCT04645199).
    These data indicated that early relapse within 18 months (ER18) after initial treatment was the best time point for identifying early progression and dynamic high-risk in MM. The ER18 population (114 of 587, 19.4%) presented with more aggressive biologic features and the inferior response to treatment compared to a reference cohort (p < .001), with a significantly short median overall survival (OS) of 28.9 months. Multivariate analyses confirmed the most significant prognostic value of ER18 on OS in the context of International Staging System stage, elevated lactate dehydrogenase, thrombocytopenia, cytogenetic abnormalities, and treatment (hazard ratio, 4.467; p < .001). The authors also described the specific transitions from static risk profile to dynamic risk distribution and then constructed a mixed-risk-pattern to identify four novel populations with distinct survival (p < .001). Additionally, the authors proposed a second-state model that predicts dynamic risk changes, enabling a complementary role to the Revised International Staging System model in facilitating individualized systematic treatment.
    Collectively, this study concludes that ER18 is a simple and dynamic prognostic predictor in MM. In addition to static risk assessment, dynamic risk plays an important role in survival prediction.

    背景:在口服普萘洛尔至少6个月的第一个疗程(在获得上市许可后开始)后,与婴儿血管瘤(IH)早期复发相关的因素尚未得到研究。
    目的:根据目前的处方指南,确定与口服普萘洛尔治疗IH患儿早期复发风险相关的因素。
    方法:我们进行了多中心,回顾性,病例对照研究,使用OuestDataHub数据库。纳入2014年6月31日至2021年12月31日期间口服普萘洛尔治疗IH至少6个月的所有儿童,以及在治疗停止后至少3个月的随访。1例被定义为IH在治疗停止后三个月内复发;每个病例在治疗开始时和中心的年龄相匹配,四个(无复发)对照。复发与治疗或IH特征之间的关联表示为单变量和多变量条件逻辑回归的比值比(OR)。
    结果:共纳入225名儿童。其中,36(16%)早期复发。在多变量分析中,深IH成分是早期复发的危险因素[OR=8.93;95CI:1.0~78.9,p=0.05].普萘洛尔低于3mg/kg/天的剂量水平可防止早期复发[OR=0.11;95CI:0.02-0.7,p=0.02]。普萘洛尔停药前逐渐减少与早期复发的风险较低无关。
    结论:晚期和早期复发的危险因素可能不同。早期与早期的危险因素调查IH晚期复发现在是必要的.
    BACKGROUND: The factors associated with early relapse of infantile haemangioma (IH) after a first course of treatment with oral propranolol for at least six months (initiated after the marketing authorization had been granted) have not previously been investigated.
    OBJECTIVE: To identify factors associated with the risk of early relapse in children with IH treated with oral propranolol according to the current prescribing guidelines.
    METHODS: We performed a multicentre, retrospective, case-control study, using the Ouest Data Hub database. All children treated for at least 6 months with oral propranolol for IH between 31 June 2014 and 31 December 2021, and with a follow-up visit at least three months after treatment discontinuation were included. A case was defined as relapse of IH within three months of treatment discontinuation; each case was matched for age at treatment initiation and for centre, with four (relapse-free) controls. The association between relapse and treatment or IH characteristics was expressed as an odds ratio (OR) from univariate and multivariate conditional logistic regressions.
    RESULTS: A total of 225 children were included. Of these, 36 (16%) relapsed early. In a multivariate analysis, a deep IH component was a risk factor for early relapse [OR = 8.93; 95%CI: 1.0-78.9, p = 0.05]. A propranolol dosage level of less than 3 mg/kg/day protected against early relapse [OR = 0.11; 95%CI: 0.02-0.7, p = 0.02]. Tapering before propranolol discontinuation was not associated with a lower risk of early relapse.
    CONCLUSIONS: The risk factors for late and early relapse are probably different. Investigation of the risk factors for early vs. late IH relapse is now warranted.
