    临床医生在患者接触期间的时间有限,这可能导致患者的担忧得不到解决。这项研究的目的是测试电子患者报告的结果生活质量工具(PROQOL)是否可以改善癌症患者的生活质量(QOL)。
    这项单中心非盲前瞻性临床试验将患者(2:1)随机接受PROQOL与常规治疗(UC)。纳入了两个患者队列:血液系统恶性肿瘤(多发性骨髓瘤[MM]或轻链淀粉样变性[AL])和实体瘤(头颈部[H/N]或妇科[GYN]恶性肿瘤)。主要终点是通过单项目线性模拟自我评估测量的患者报告的12个月时的QOL。对患者的价值和对临床医生工作流程的影响是使用“值得吗”调查来衡量的。该研究有能力检测组间0.5个标准偏差差异。
    共纳入383例患者,171配MM,62AL,113GYN,2016年7月至2018年4月期间为37H/N,随访12个月。男性患者为171例(44.6%),中位年龄为62岁(范围31-87)。最常选择的关注是身体健康(30.9%),其次是癌症诊断和治疗(29.1%)。12个月时,PROQOL的平均QOL为7.12,UC(0-10量表)为6.98,总体上(p=0.56)或在血液学或实体瘤队列中没有组间差异,分别。在患者中,74%的人认为PROQOL工具是值得的,86%的人会再次选择PROQOL,81%的人会推荐给其他人。在临床医生中,95%的人回答说PROQOL是值得的,并且认为PROQOL不会对他们的工作流程产生负面影响。
    虽然我们没有证明PROQOL组和UC组之间的QOL差异,但PROQOL工具在确定患者的主要关注点方面具有相当大的价值,对患者和临床医生来说都是值得的。
    UNASSIGNED: Clinicians have limited time during patient encounters which can result in patients\' concerns not being addressed. This study\'s objective was to test whether an electronic patient-reported outcome quality of life tool (PROQOL) in which patients identify their primary concern during clinic visits improves cancer patient quality of life (QOL).
    UNASSIGNED: This single center non-blinded prospective clinical trial randomized patients (2:1) to PROQOL versus usual care (UC). Two patient cohorts were enrolled: those with hematologic malignancies (multiple myeloma [MM] or light chain amyloidosis [AL]) and solid tumors (head and neck [H/N] or gynecologic [GYN] malignancies). Primary endpoint was patient-reported QOL at 12 months measured by a single-item Linear Analog Self-Assessment. Value to patients and impact on clinician workflow was measured using a \"was it worth it\" survey. The study was powered to detect a 0.5 standard deviation difference between groups.
    UNASSIGNED: Overall 383 patients were enrolled, 171 with MM, 62 AL, 113 GYN, and 37 H/N between July 2016 and April 2018, with 12-month follow-up. There were 171 (44.6%) male patients and median age was 62 years (range 31-87). The most often selected concern was physical health (30.9%), and second was cancer diagnosis and treatment (29.1%). Mean QOL was 7.12 for PROQOL and 6.98 for UC (0-10 scale) at 12 months, with no between-group difference overall (p = 0.56) or within hematologic or solid tumor cohorts, respectively. Among patients, 74% thought the PROQOL tool was worthwhile, 86% would choose PROQOL again, and 81% would recommend it to others. Among clinicians, 95% responded that PROQOL was worthwhile and did not think that PROQOL negatively impacted their workflow.
    UNASSIGNED: Although we did not demonstrate a QOL difference between PROQOL and UC groups; the PROQOL tool held considerable value in identifying patients\' main concerns over time and was worthwhile for patients and clinicians.

    目的:血液病患者与非血液病患者相比,COVID-19的特征很少被分析。我们的目的是分析COVID-19血液学患者与非血液学患者的临床特征和结局是否存在差异。
    方法:在2所大学医院进行回顾性队列研究,纳入SEMICOVID19数据库中的实验室确诊COVID-19患者。将患有基础血液病的队列与年龄和COVID-19日期相匹配的无血液病的对照组进行比较(1:2)。
    结果:纳入了2020年3月至5月的71例病例和142例对照。20人(28.1%)最近接受过化疗。12例(16.9%)为干细胞移植受者(SCT)。11例(15.5%)与COVID-19诊断同时出现中性粒细胞减少。血液病患者出现ARDS(58.5vs20.7%,p=0.0001),血栓性并发症(15.7vs2.1%,p=0.002),DIC(5.7vs0.0%,p=0.011),心力衰竭(14.3vs4.9%,p=0.029)和要求入住ICU(15.5vs2.8%,p=0.001),MV(14.1%对2.1%,p0.001),类固醇(64.8vs33.1%,p=0.0001),托珠单抗(33.8%vs8.5%,p=0.0001)或anakinra治疗(9.9%vs0%,p=0.0001)更频繁。住院死亡率明显更高(38.0%vs18.3%,p=0.002)。
    结论:我们的结果表明,与非血液病患者相比,COVID-19在血液病患者中的预后较差,独立于年龄,ARDS和血栓性并发症的发展导致更高的院内死亡率。
    OBJECTIVE: The characteristics of COVID-19 in haematologic patients compared to non-haematologic patients have seldom been analyzed. Our aim was to analyze whether there are differences in clinical characteristics and outcome of haematologic patients with COVID-19 as compared to non-haematologic.
    METHODS: Retrospective cohort study in 2 University hospitals of patients admitted with laboratory-confirmed COVID-19 included in the SEMICOVID19 database. The cohort with underlying haematologic disease was compared to a cohort of age and date-of-COVID-19-matched controls without haematologic disease (1:2).
    RESULTS: 71 cases and 142 controls were included from March-May 2020.Twenty (28.1%) had received recent chemotherapy. Twelve (16.9%) were stem cell transplant recipients (SCT). Eleven (15.5%) were neutropenic concurrently with COVID-19 diagnosis.Haematologic patients presented ARDS (58.5 vs 20.7%, p = 0.0001), thrombotic complications (15.7 vs 2.1%, p = 0.002), DIC (5.7 vs 0.0%, p = 0.011), heart failure (14.3 vs 4.9%, p = 0.029) and required ICU admission (15.5 vs 2.8%, p = 0.001), MV (14.1% vs 2.1%, p 0.001), steroid (64.8 vs 33.1%, p = 0.0001), tocilizumab (33.8 vs 8.5%, p = 0.0001) or anakinra treatment (9.9% vs 0%, p = 0.0001) more often. In-hospital mortality was significantly higher (38.0% vs 18.3%, p = 0.002).
    CONCLUSIONS: Our results suggest COVID-19 has worse outcomes in haematologic patients than in non-haematologic, independently of age, and that the development of ARDS and thrombotic complications drive the higher in-hospital mortality.

    现在使用术语“免疫原性细胞死亡”(ICD)来表示功能上独特的凋亡形式,足以使免疫活性宿主产生针对死细胞相关抗原的适应性免疫反应。当用作独立的治疗干预措施时,几种药物被认为具有激发ICD的能力。这些包括临床上常规使用的各种化疗药物(例如,阿霉素,表柔比星,伊达比星,米托蒽醌,博来霉素,硼替佐米,环磷酰胺和奥沙利铂)以及一些仍在临床前或临床开发中的抗癌剂(例如,埃坡霉素家族的一些微管抑制剂)。此外,一些药物能够将细胞死亡的非免疫原性实例转化为真正的ICD,因此可以在组合方案中用作化疗佐剂。强心苷就是这种情况,比如地高辛和洋地黄毒苷,和唑来膦酸.这里,我们讨论了基于ICD诱导剂的抗癌化疗的最新进展。
    The term \"immunogenic cell death\" (ICD) is now employed to indicate a functionally peculiar form of apoptosis that is sufficient for immunocompetent hosts to mount an adaptive immune response against dead cell-associated antigens. Several drugs have been ascribed with the ability to provoke ICD when employed as standalone therapeutic interventions. These include various chemotherapeutics routinely employed in the clinic (e.g., doxorubicin, epirubicin, idarubicin, mitoxantrone, bleomycin, bortezomib, cyclophosphamide and oxaliplatin) as well as some anticancer agents that are still under preclinical or clinical development (e.g., some microtubular inhibitors of the epothilone family). In addition, a few drugs are able to convert otherwise non-immunogenic instances of cell death into bona fide ICD, and may therefore be employed as chemotherapeutic adjuvants within combinatorial regimens. This is the case of cardiac glycosides, like digoxin and digitoxin, and zoledronic acid. Here, we discuss recent developments on anticancer chemotherapy based on ICD inducers.

    先前未治疗的患者(n=34),用抗原特异性癌症免疫治疗剂tecemotide(L-BLP25)反复免疫接种缓慢进展的无症状I/II期多发性骨髓瘤或常规抗肿瘤治疗后处于稳定反应/平台期的II/III期多发性骨髓瘤.此外,患者被随机分配给单次或多次低剂量环磷酰胺以抑制调节性T细胞(Treg).用tememotide免疫导致47%的患者诱导/增强粘蛋白1特异性免疫反应。免疫应答似乎涉及涉及CD4和CD8T细胞的Th1样细胞免疫应答。单次给药与多次给药环磷酰胺以及与没有预先存在的粘蛋白1免疫力。在45%的可评估患者中观察到M蛋白浓度随时间的斜率降低(但未达到常规抗肿瘤药物反应的临床标准)。主要是那些没有与预先存在的粘蛋白1免疫和早期疾病的患者。在接受单次或多次环磷酰胺给药的患者中没有发现差异。用替莫肽治疗通常耐受性良好。重复vs.单次给药环磷酰胺对Treg数量无影响,在一例致死性脑炎被评估为可能与研究相关后停止给药.替考莫肽免疫疗法在相当一部分患者中诱导粘蛋白1特异性细胞免疫反应,初步证据表明部分患者的M蛋白浓度时间曲线发生了变化。
    Patients (n = 34) with previously untreated, slowly progressive asymptomatic stage I/II multiple myeloma or with stage II/III multiple myeloma in stable response/plateau phase following conventional anti-tumor therapy were immunized repeatedly with the antigen-specific cancer immunotherapeutic agent tecemotide (L-BLP25). Additionally, patients were randomly allocated to either single or multiple low doses of cyclophosphamide to inhibit regulatory T cells (Treg). Immunization with tecemotide resulted in the induction/augmentation of a mucin 1-specific immune response in 47% of patients. The immune responses appeared to involve a Th1-like cellular immune response involving CD4 and CD8 T cells. The rate of immune responses was similar with single versus multiple dosing of cyclophosphamide and in patients with vs. without pre-existing mucin 1 immunity. On-treatment reductions in the slope of M-protein concentration over time (but not fulfilling clinical criteria for responses with conventional anti-tumor agents) were observed in 45% of evaluable patients, predominantly in those without versus with pre-existing mucin 1 immunity and in patients with early stage disease. No differences were seen in patients receiving single or multiple cyclophosphamide dosing. Treatment with tecemotide was generally well tolerated. Repeated vs. single dosing of cyclophosphamide had no impact on Treg numbers and was stopped after a case of fatal encephalitis that was assessed as possibly study-related. Tecemotide immunotherapy induces mucin 1-specific cellular immune responses in a substantial proportion of patients, with preliminary evidence of changes in the M-protein concentration time curve in a subset of patients.
