    Respiratory papilloma is a relatively common benign tumor of the respiratory tract, and a few patients may develop malignant changes. The disease has an insidious onset and lacks specific clinical manifestations, and its manifestations are closely related to the growth mode, location and size of the tumor. It can involve multiple parts, such as the larynx, trachea, bronchus, and lung parenchyma, which cause coughing, hoarseness, dysphonia, and, in severe cases, may lead to obstruction of the respiratory tract. At present, the treatment of respiratory papilloma lacks standardization, and there is no effective method to cure the disease. Surgery remains the main treatment for alleviating patients\' symptoms and preventing airway obstruction. However, due to the high recurrence rate of respiratory papilloma, multiple surgeries are often needed, which reduces the quality of life of patients and increases their disease burden and economic burden. Bevacizumab, a vascular endothelial growth factor-binding antibody inhibitor, is a promising adjuvant treatment modality that shows good potential for reducing symptoms and the frequency of surgery. This article aimed to review the efficacy and safety of bevacizumab for the treatment of respiratory papilloma and discuss the differences and efficacy of the systemic application and intralesional injection of bevacizumab for the treatment of respiratory papilloma.
    呼吸道乳头状瘤是呼吸道较常见的良性肿瘤,少数可发生恶变。该病起病隐匿,缺乏特异性临床表现,其表现与肿瘤生长方式、部位、大小密切相关,可有喉、气管、支气管、肺实质等多个部位受累,引起咳嗽、声音嘶哑、发音困难,严重者可致呼吸道梗阻。目前,呼吸道乳头状瘤的治疗缺乏规范统一的标准,且尚无治愈该病的有效方法,手术是减轻患者症状、预防气道梗阻的主要治疗方式。然而呼吸道乳头状瘤复发率高,患者往往需要经历多次手术治疗,频繁的手术降低患者的生活质量,增加患者的疾病负担与经济负担。贝伐珠单抗作为血管内皮生长因子结合抗体抑制剂,是一种有希望的辅助治疗方式,在减轻症状、减少手术频率方面表现出较好的潜力。本文主要对贝伐珠单抗治疗呼吸道乳头状瘤的有效性及安全性进行综述,并探讨全身性应用和病灶内注射贝伐珠单抗治疗呼吸道乳头状瘤的差异及疗效。.

    目的:比较玻璃体内贝伐单抗(IVB)单药治疗和玻璃体内贝伐单抗联合激光光凝(LPC)在同一疗程中应用于侵袭性早产儿视网膜病变(A-ROP)的结果。
    方法:本研究包括37例诊断为A-ROP并接受治疗的患者的67只眼。第一组包括使用抗血管内皮生长因子剂注射液单药治疗A-ROP的49只眼。第二组由接受注射治疗和LPC治疗的18只眼组成。调查两组患者的临床表现,并对其治疗结果进行比较。
    结果:在第一组49只眼中的19只(38%)中观察到复发,但在第二组中没有任何病例复发。虽然只有IVB应用于8例复发病例,11例患者采用LPC和IVB联合治疗。在接受IVB单一疗法作为复发治疗的8例病例中的2例以及接受LPC和IVB治疗的11例病例中的3例中检测到第二次复发。两组治疗结果差异无统计学意义(P=0.181)。
    结论:我们认为在A-ROP病例中同时应用LPC和IVB联合治疗是一种有效的方法。特别是对患者参加随访预约的能力存在担忧的情况。
    OBJECTIVE: To compare the results of intravitreal bevacizumab (IVB) monotherapy and combined intravitreal bevacizumab and laser photocoagulation (LPC) therapies applied in the same session to patients with aggressive retinopathy of prematurity (A-ROP) in our clinic.
    METHODS: The study included 67 eyes of 37 patients diagnosed with A-ROP and treated. Forty-nine eyes treated with anti-vascular endothelial growth factor agent injection monotherapy for A-ROP treatment were included in the first group. The second group consisted of 18 eyes that received injection therapy and LPC treatment. The clinical findings of the two groups were investigated, and their treatment results were compared.
    RESULTS: Recurrence was observed in 19 of the 49 (38%) eyes in the first group, but there was no recurrence in any of the cases in the second group. While only IVB was applied to eight cases with recurrence, the combination of LPC and IVB treatment was applied to 11 cases. A second recurrence was detected in two of the eight cases that had received IVB monotherapy as a treatment for recurrence and in three of the 11 cases that had received LPC and IVB. The treatment outcomes of the two groups did not statistically significantly differ (P = 0.181).
    CONCLUSIONS: We consider that the combined simultaneous LPC and IVB treatment we applied in A-ROP cases is an effective approach, particularly for cases where there are concerns about the patient\'s ability to attend follow-up appointments.

    这是一个总结,描述了一项名为SUNLIGHT的3期临床试验的结果。该研究观察了口服氟尿苷/替吡草定加静脉给药贝伐单抗治疗转移性结直肠癌(mCRC)患者的治疗效果。这项研究包括癌症在不超过两次治疗后生长或扩散到其原始位置的人。研究中的患者接受了三氟尿苷/替吡草胺联合贝伐单抗治疗,或者单独接受了三氟尿苷/替吡草胺治疗。该研究的目的是观察与单独使用氟尿苷/替吡草定联合贝伐单抗治疗相比,使用氟尿苷/替吡草定联合贝伐单抗治疗后的寿命,并了解氟尿苷/替吡草定联合贝伐单抗在减缓癌症扩散方面的效果。研究人员还研究了服用这些药物的副作用以及治疗如何影响人们的身体机能。
    组合组的患者比单独接受氟尿苷/替哌嘧啶的患者(7.5个月)寿命更长(中位数为10.8个月)。此外,接受联合治疗的患者的癌症恶化时间(中位数为5.6个月)比接受单用氟尿苷/替哌嘧啶的患者(2.4个月)更长.联合治疗(中位数为9.3个月)患者的身体功能比单用氟尿苷/替哌嘧啶(6.3个月)需要更长的时间恶化,通过治疗对人们进行日常生活活动能力的影响来衡量。两个治疗组中最常见的副作用是白细胞水平低,称为中性粒细胞(中性粒细胞减少症),恶心,和低水平的健康红细胞(贫血)。
    研究结果表明,口服氟尿苷/替吡草定加静脉(IV)贝伐单抗治疗可帮助难治性mCRC患者寿命更长,并保持良好的身体功能,它可以减缓他们癌症的恶化。临床试验注册:NCT04737187(SUNLIGHT)(ClinicalTrials.gov)。
    UNASSIGNED: This is a summary describing the results from a phase 3 clinical trial called SUNLIGHT. The study looked at treatment with orally administered trifluridine/tipiracil plus intravenously administered bevacizumab in people with metastatic colorectal cancer (mCRC) that is refractory to treatment.This study included people whose cancer had grown or spread beyond its original location after no more than two previous treatments. People in the study received either the combination of trifluridine/tipiracil plus bevacizumab or they received trifluridine/tipiracil alone. The aims of the study were to see how long people lived after treatment with trifluridine/tipiracil plus bevacizumab compared with trifluridine/tipiracil alone and to find out how well the combination of trifluridine/tipiracil plus bevacizumab worked at slowing down the spread of the cancer. Researchers also looked at side effects from taking the medicines and at how treatment affected people\'s physical functioning.
    UNASSIGNED: People in the combination group lived longer (a median of 10.8 months) than people who received trifluridine/tipiracil alone (7.5 months). In addition, the time it took for the cancer to worsen was longer for those who received the combination treatment (a median of 5.6 months) compared with those who received trifluridine/tipiracil alone (2.4 months). People\'s physical functioning took longer to worsen with combination therapy (a median of 9.3 months) than it did with trifluridine/tipiracil alone (6.3 months), as measured by the impact of treatment on people\'s ability to carry out daily living activities. The most common side effects in both treatment groups were low levels of white blood cells, known as neutrophils (neutropenia), nausea, and low levels of healthy red blood cells (anemia).
    UNASSIGNED: The results from the study suggest that treatment with oral trifluridine/tipiracil plus intravenous (IV) bevacizumab could help people with refractory mCRC live longer and maintain good physical functioning, and it could slow the worsening of their cancer.Clinical Trial Registration: NCT04737187 (SUNLIGHT) (ClinicalTrials.gov).

    背景:Lenvatinib(LEN)和atezolizumab+贝伐单抗(A+B)已经彻底改变了晚期肝细胞癌(HCC)的治疗模式。在这些具有里程碑意义的试验之前,索拉非尼(SOR)作为标准的一线治疗已有十年。我们的研究旨在评估在SOR时代(2008-2018)治疗的HCC患者的结果,与SOR时代(2018-2021)相比,其中主要的一线治疗是LEN或A+B。
    方法:本研究的纳入标准是加拿大阿尔伯塔省的所有HCC患者,他们在2008年1月1日至2021年12月31日期间在癌症中心开始一线全身治疗。生存结果,包括总生存期(OS)和无进展生存期(PFS),以及临床医生评估的反应率(RR),进行回顾性分析。
    结果:总共372名患者,230人在SOR时代接受治疗,142人在后SOR时代接受治疗。SOR时代和后SOR时代群体的人口统计学和临床特征如下,年龄中位数分别为63岁和64岁,80%和81%为男性,24%和11%是东亚种族。在接受全身治疗之前,40%和33%接受了TACE,7%和9%收到TARE,在这两个时代,分别有3%和14%收到SBRT,分别。在后SOR时代,患者接受了A+B(23%),LEN(51%),和SOR(23%)作为一线治疗。RR有统计学上显著的改善(15%vs.26%;p=0.02),中位PFS(3.8个月vs.7.9个月;p<0.0001),和中位OS(9.8个月与17.0个月;p<0.0001)。
    结论:在这项回顾性多中心真实世界研究中,在SOR后时代接受治疗的HCC患者,LEN和A+B是常用的一线治疗方法,表现出卓越的操作系统,PFS,和RR与SOR时代接受治疗的患者相比。这项研究的结果肯定了在现实世界中取得的切实进展,通过在过去15年中的治疗进步,提高了HCC患者的结果。
    BACKGROUND: Lenvatinib (LEN) and atezolizumab + bevacizumab (A + B) have drastically changed the treatment paradigm for advanced hepatocellular carcinoma (HCC). Before these landmark trials, sorafenib (SOR) served as the standard first-line treatment for a decade. Our study aimed to assess the outcomes of HCC patients treated during the SOR era (2008-2018) in contrast to those in the post-SOR era (2018-2021), of which the predominant first-line treatments were LEN or A + B.
    METHODS: Inclusion criteria of the study were all HCC patients in the Canadian province of Alberta who started first-line systemic therapy at cancer centers between 1 January 2008 and 31 December 2021. Survival outcomes, including overall survival (OS) and progression-free survival (PFS), along with clinician-assessed response rate (RR), were subject to retrospective analysis.
    RESULTS: Of 372 total patients, 230 received treatment in the SOR era and 142 in the post-SOR era. The demographic and clinical characteristics for the SOR era and post-SOR era groups are as follows, respectively: the median age was 63 and 64 years, 80% and 81% were male, and 24% and 11% were of East Asian ethnicity. Before receiving systemic treatment, 40% and 33% received TACE, 7% and 9% received TARE, and 3% and 14% received SBRT in the two eras, respectively. In the post-SOR era, patients received A + B (23%), LEN (51%), and SOR (23%) as first-line treatment. There was a statistically significant improvement in RR (15% vs. 26%; p = 0.02), median PFS (3.8 months vs. 7.9 months; p < 0.0001), and median OS (9.8 months vs. 17.0 months; p < 0.0001).
    CONCLUSIONS: In this retrospective multicenter real-world study, HCC patients treated in the post-SOR era, where LEN and A + B were commonly used first-line treatments, exhibited superior OS, PFS, and RR compared to patients treated in the SOR era. The findings of this study affirm the tangible progress achieved in the real world in enhancing outcomes for HCC patients through advancements in treatments over the past 15 years.

    不幸的是,卵巢癌通常仅在晚期才被诊断,也是最致命的妇科癌症。另一个问题是接受治疗的患者具有很高的疾病复发风险。此外,卵巢癌在分子方面非常多样化,组织学特征和突变。许多患者也可能出现铂类耐药,导致对后续治疗的反应不佳。改善卵巢癌患者的预后,预计将更好地现有并实施新的,有希望的治疗方法。靶向治疗似乎非常有希望。目前,贝伐单抗-一种VEGF抑制剂和奥拉帕尼-一种聚ADP-核糖聚合酶抑制剂的治疗被批准。未来值得考虑的其他方法包括:叶酸受体α,免疫检查点或其他免疫疗法。提高卵巢癌的治疗水平,改善分子特征的测定也很重要,以描述和了解哪一组患者将从给定的治疗方法中受益最大。这很重要,因为接受卵巢癌治疗的患者中有更大的机会存活更长时间而不复发。
    Unfortunately, ovarian cancer is still diagnosed most often only in an advanced stage and is also the most lethal gynecological cancer. Another problem is the fact that treated patients have a high risk of disease recurrence. Moreover, ovarian cancer is very diverse in terms of molecular, histological features and mutations. Many patients may also develop platinum resistance, resulting in poor response to subsequent lines of treatment. To improve the prognosis of patients with ovarian cancer, it is expected to make better existing and implement new, promising treatment methods. Targeted therapies seem very promising. Currently, bevacizumab - a VEGF inhibitor and therapy with olaparib - a polyADP-ribose polymerase inhibitor are approved. Other methods worth considering in the future include: folate receptor α, immune checkpoints or other immunotherapy methods. To improve the treatment of ovarian cancer, it is also important to ameliorate the determination of molecular features to describe and understand which group of patients will benefit most from a given treatment method. This is important because a larger group of patients treated for ovarian cancer can have a greater chance of surviving longer without recurrence.

    目的:阿特珠单抗联合贝伐单抗(Atez+Bev)给药前血清白细胞介素-6(IL-6)是用Atez+Bev治疗的肝细胞癌(HCC)患者的预后生物标志物。我们先前发现,在AtezBev治疗期间,中性粒细胞与淋巴细胞的比率和血清趋化因子水平作为预后生物标志物更有用。因此,我们检查了血清IL-6对肝癌患者Atez+Bev疗效的预测能力。
    方法:我们招募了94例接受Atez+Bev治疗的HCC患者。通过动态计算机断层扫描或磁共振成像评估初始反应。在AtezBev的第二个疗程之前和开始时测量血清中IL-6的水平。随后,评估IL-6水平与治疗疗效的关系.
    结果:在初始评估中,进行性疾病患者在第二疗程开始时的IL-6水平倾向于高于非进行性疾病患者(P=0.054)。此外,截止值(7.4pg/mL)可用于按总生存期对患者进行分层(即低与高:未达到vs21.4个月,分别,P=0.001)和无进展生存期(低vs高:11.9vs5.2个月,分别,P=0.004)。这一结果在接受Atez+Bev作为一线治疗的HCC患者中重现。在多变量分析中,第二个疗程开始时的IL-6水平是无进展和总生存期的独立预测因素。
    结论:第二疗程开始时血清IL-6水平可预测HCC的Atez+Bev疗效和预后。
    OBJECTIVE: Serum interleukin-6 (IL-6) before the administration of atezolizumab plus bevacizumab (Atez + Bev) is a prognostic biomarker in patients with hepatocellular carcinoma (HCC) treated with Atez + Bev. We previously revealed that the neutrophil-to-lymphocyte ratio and serum chemokine levels during treatment with Atez + Bev were more useful as prognostic biomarkers. Therefore, we examined the predictive ability of serum IL-6 for the efficacy of Atez + Bev in patients with HCC.
    METHODS: We enrolled 94 patients with HCC who received treatment with Atez + Bev. Initial responses were assessed through dynamic computed tomography or magnetic resonance imaging. The levels of IL-6 in serum were measured before and at the initiation of the second course of Atez + Bev. Subsequently, the relationship of IL-6 levels with treatment efficacy was evaluated.
    RESULTS: IL-6 levels at the initiation of the second course tended to be higher in patients with progressive disease versus those with non-progressive disease in the initial evaluation (P = 0.054). Moreover, the cutoff value (7.4 pg/mL) was useful in stratifying patients by overall survival (i.e. low vs high: not reached vs 21.4 months, respectively, P = 0.001) and progression-free survival (low vs high: 11.9 vs 5.2 months, respectively, P = 0.004). This result was reproduced in patients with HCC who received Atez + Bev as first-line therapy. In the multivariate analyses, IL-6 levels at the initiation of the second course were independent predictive factors for progression-free and overall survival.
    CONCLUSIONS: Serum levels of IL-6 at the initiation of the second course of treatment may predict Atez + Bev efficacy and prognosis in HCC.

    阿特珠单抗(PD-L1抑制剂)加贝伐单抗(AB)和辛替单抗(PD-1抑制剂)加贝伐单抗(SB)均被推荐为中国晚期肝细胞癌(HCC)的一线方案。两种方案联合经血管介入治疗不可切除的HCC(uHCC)的疗效差异尚不清楚。我们回顾性分析了在三个中心同时结合AB或SB与经动脉化疗栓塞(TACE)和基于FOLFOX的肝动脉灌注化疗(HAIC)治疗的uHCC患者。客观反应率(ORR),无进展生存期(PFS),比较了总生存期(OS)和治疗相关不良事件(TRAEs).共纳入188例患者,92和96给药A+B+TACE-HAIC(ABTH)和S+B+TACE-HAIC(SBTH),分别。ORR(62.0vs.70.8%,分别为;P=0.257)和疾病控制率(88.0vs.93.8%,P=0.267)根据mRECIST标准,组间相似。ABTH与SBTH相比没有显示出生存优势,中位PFS时间为11.7个月和13.0个月,分别为(HR=0.81,95%CI,0.52-1.26,P=0.35)和相似的OS时间(HR=1.19,95%CI,0.32-4.39,P=0.8)。组间3-4级TRAE没有观察到显著差异。PD-L1或PD-1抑制剂加贝伐单抗联合TACE-HAIC具有同样出色的治疗效果,且不良事件可控。代表uHCC的有希望的治疗选择。
    Both atezolizumab (a PD-L1 inhibitor) plus bevacizumab (A+B) and sintilimab (a PD-1 inhibitor) plus bevacizumab (S+B) are recommended as the first-line regimen for advanced hepatocellular carcinoma (HCC) in China. Different efficacy between the two regimens combined with transvascular intervention for unresectable HCC (uHCC) remain unknown. We retrospectively analyzed uHCC patients treated in three centers by simultaneous combination of A+B or S+B with transarterial chemoembolization (TACE) and FOLFOX-based hepatic arterial infusion chemotherapy (HAIC). Objective response rate (ORR), progression-free survival (PFS), overall survival (OS) and treatment-related adverse events (TRAEs) were compared. Totally 188 patients were included, with 92 and 96 administered A+B+TACE-HAIC (ABTH) and S+B+TACE-HAIC (SBTH), respectively. ORRs (62.0 vs. 70.8%, respectively; P = 0.257) and disease control rates (88.0 vs. 93.8%, P = 0.267) were similar between groups by the mRECIST criteria. ABTH showed no survival advantage over SBTH, with median PFS times of 11.7 months and 13.0 months, respectively (HR = 0.81, 95% CI, 0.52-1.26, P = 0.35) and similar OS times (HR = 1.19, 95% CI, 0.32-4.39, P = 0.8). No significant differences were observed in grade 3-4 TRAEs between groups. Either PD-L1 or PD-1 inhibitor plus bevacizumab combined with TACE-HAIC have similarly excellent therapeutic efficacy with manageable adverse events, representing promising treatment options for uHCC.

    目的:肝细胞癌(HCC)的治疗前景,包括免疫检查点抑制剂,已大大扩展。然而,不可切除的肝癌合并门静脉癌栓(PVTT)的患者继续面临不良预后.这项研究检查了接受阿特珠单抗加贝伐单抗(ATZBEV)或肝动脉灌注化疗(HAIC)治疗的PVTT晚期HCC患者的生存结果和影响生存率的决定因素。
    方法:在2003年12月至2023年6月之间,48例晚期HCC伴PVTT接受了ATZBEV(16例)或HAIC(32例)的治疗。
    结果:分析显示,ATZ+BEV和HAIC组之间的总生存期(OS)或治疗效果没有显着差异(ATZ+BEV:10.0个月,HAIC:15.3个月)。用ATZ+BEV或HAIC治疗导致ALBI评分的最小改变和肝功能保留。OS的独立预后因素,通过多元逻辑回归确定,包括血清甲胎蛋白水平>400ng/ml[风险比(HR)=1.94;p=0.001],存在五个以上的肿瘤(HR=1.55;p=0.043),和Child-Pugh评分(HR=2.53;p=0.002)。
    结论:这项研究显示,接受ATZ+BEV的患者和接受HAIC治疗的患者之间的OS和反应率没有显著差异。晚期肝癌患者PVTT的生存与肝功能的保存密切相关,强调需要进行更多研究以加强对该患者人群的治疗方法。
    OBJECTIVE: The landscape of treatments for hepatocellular carcinoma (HCC), including immune checkpoint inhibitors, has expanded significantly. However, unresectable HCC patients with portal vein tumor thrombus (PVTT) continue to face a poor prognosis. This investigation examined the survival outcomes and determinants influencing survival rates in advanced HCC patients with PVTT undergoing treatment with atezolizumab plus bevacizumab (ATZ+BEV) or hepatic arterial infusion chemotherapy (HAIC).
    METHODS: Between December 2003 and June 2023, 48 advanced HCC with PVTT underwent treatment with either ATZ+BEV (16 patients) or HAIC (32 patients).
    RESULTS: The analysis revealed no significant disparities in overall survival (OS) or treatment efficacy between the ATZ+BEV and HAIC groups (ATZ+BEV: 10.0 months, HAIC: 15.3 months). Treatment with either ATZ+BEV or HAIC resulted in minimal alterations in the ALBI score and preserved hepatic function. Independent prognostic factors for OS, identified via multivariate logistic regression, included serum α-fetoprotein levels >400 ng/ml [hazard ratio (HR)=1.94; p=0.001], the existence of more than five tumors (HR=1.55; p=0.043), and the Child-Pugh score (HR=2.53; p=0.002).
    CONCLUSIONS: This investigation revealed no significant variance in OS and response rates between patients receiving ATZ+BEV and those treated with HAIC. The survival of advanced HCC patients with PVTT is intricately linked to the preservation of liver function, emphasizing the necessity for additional research to enhance treatment approaches for this patient population.

    肺癌是最常见和最致命的癌症之一。临床前模型对于研究考虑肿瘤遗传学的新疗法和组合至关重要。我们已经从具有不同遗传背景的细胞系中建立了表达荧光素酶基因的细胞系,常见于肺腺癌患者。我们通过测试这些品系对多种药物的反应来表征这些品系。因此,我们开发了非小细胞肺癌原位临床前小鼠模型,其移植效率非常高.这些模型可以轻松监测肿瘤的生长,特别是对治疗的反应,以及肿瘤细胞在体内的传播。我们表明,奥希替尼(第三代酪氨酸激酶抑制剂靶向突变的EGFR)和贝伐单抗(抗血管生成靶向VEGF)的联合治疗可以对EGFR突变的肿瘤产生有益的治疗效果。我们还表明,在奥希替尼治疗的肿瘤中加入阿法替尼导致肿瘤生长抑制。使用司美替尼或辛伐他汀没有观察到这种效果。因此,这些临床前小鼠模型可以测试创新的治疗组合,也是研究抗性机制的首选工具。
    Lung cancer is one of the most common and deadliest cancers. Preclinical models are essential to study new therapies and combinations taking tumor genetics into account. We have established cell lines expressing the luciferase gene from lines with varied genetic backgrounds, commonly encountered in patients with pulmonary adenocarcinoma. We have characterized these lines by testing their response to multiple drugs. Thus, we have developed orthotopic preclinical mouse models of NSCLC with very high engraftment efficiency. These models allow the easy monitoring of tumor growth, particularly in response to treatment, and of tumor cells dissemination in the body. We show that concomitant treatment with osimertinib (3rd generation tyrosine kinase inhibitor targeting mutated EGFR) and bevacizumab (anti-angiogenic targeting VEGF) can have a beneficial therapeutic effect on EGFR-mutated tumors. We also show that the addition of afatinib to osimertinib-treated tumors in escape leads to tumor growth inhibition. No such effect is observed with selumetinib or simvastatin. These preclinical mouse models therefore make it possible to test innovative therapeutic combinations and are also a tool of choice for studying resistance mechanisms.
