    尽管质子束治疗(PBT)在全球范围内受到限制,随着新设施的扩展,其用于治疗肝细胞癌(HCC)的用途逐渐增加。因此,我们进行了系统评价和荟萃分析,以调查PBT治疗HCC的最新证据.
    MEDLINE,EMBASE,科克伦图书馆,和WebofScience数据库进行了系统搜索,以招募接受PBT治疗的肝局限性HCC患者,直至2024年2月。
    从2004年至2023年的22项研究中选择了1858名接受PBT的HCC患者进行这项荟萃分析。Child-PughA级的中位数比例为86%(范围:41-100%),中位肿瘤大小为3.6cm(范围:1.2-9cm)。中位总剂量范围为55GyE至76GyE(中位数,69GyE)。PBT后3年和5年局部无进展生存期的合并率为88%(95%置信区间[CI],85-91%)和86%(95%CI,82-90%),分别。合并的3年和5年总体比率分别为60%(95%CI,54-66%)和46%(95%CI,38-54%),分别。合并的3级肝毒性率,经典放射性肝病(RILD),非经典RILD为1%,2%,1%,分别。
    目前的研究支持PBT用于HCC,并证明与其他已发表的其他放射治疗方式的研究相比,有利的长期生存率和低肝毒性。然而,需要进一步的研究来确定将受益于PBT的亚组.
    UNASSIGNED: Although access to proton beam therapy (PBT) is limited worldwide, its use for the treatment of hepatocellular carcinoma (HCC) is gradually increasing with the expansion of new facilities. Therefore, we conducted a systematic review and meta-analysis to investigate the updated evidence of PBT for HCC.
    UNASSIGNED: The MEDLINE, EMBASE, Cochrane Library, and Web of Science databases were systematically searched for studies that enrolled patients with liver-confined HCC that were treated with PBT for a cure up to February 2024.
    UNASSIGNED: A total of 1858 HCC patients receiving PBT from 22 studies between 2004 and 2023 were selected for this meta-analysis. The median proportion of Child-Pugh class A was 86% (range: 41-100%), and the median tumor size was 3.6 cm (range: 1.2-9 cm). The median total dose ranged from 55 GyE to 76 GyE (median, 69 GyE). The pooled rates of 3- and 5-year local progression-free survival after PBT were 88% (95% confidence interval [CI], 85-91%) and 86% (95% CI, 82-90%), respectively. The pooled 3- and 5-year overall rates were 60% (95% CI, 54-66%) and 46% (95% CI, 38-54%), respectively. The pooled rates of grade 3 hepatic toxicity, classic radiation-induced liver disease (RILD), and non-classic RILD were 1%, 2%, and 1%, respectively.
    UNASSIGNED: The current study supports PBT for HCC and demonstrates favorable long-term survival and low hepatic toxicities compared with other published studies on other radiotherapy modalities. However, further studies are needed to identify the subgroups that will benefit from PBT.

    背景:虽然已经定义了复发的几个风险因素,很少研究手术切除后脑膜瘤复发的地形图。从理论上预测复发部位的可能性不仅使我们能够更好地了解疾病的发病基础,从而推动新的靶向疗法的发展,但也指导决策过程的治疗策略和定制的后续行动,以减少/预防复发。
    方法:作者对EMBASE和MEDLINE电子在线数据库有关颅内脑膜瘤手术治疗后复发的地形图进行了全面而详细的系统文献综述。人口统计学和组织病理学,神经放射学和治疗数据,与复发的地形有关,以及复发的时间,进行了提取和分析。
    结果:四项研究,包括164例根据纳入标准复发,已确定。所有研究都考虑了先前硬脑膜部位复发的可能性;四分之三,这是最近的,考虑1厘米外的前硬脑膜边缘是主要的限制,以区分复发更接近前一个部位的那些更远。复发主要发生在手术床内或靠近手术床;较高的增殖指数与靠近原始部位而不是在原始部位的复发有关。
    结论:进一步的研究,包括不同复发模式的基因组表征,将更好地阐明影响复发地形的主要特征。手术后和放射治疗后颅内脑膜瘤复发的地形图分类之间的比较可以提供更多有趣的信息。
    BACKGROUND: While several risk factors for recurrences have been defined, the topographic pattern of meningioma recurrences after surgical resection has been scarcely investigated. The possibility of theoretically predicting the site of recurrence not only allows us to better understand the pathogenetic bases of the disease and consequently to drive the development of new targeted therapies, but also guides the decision-making process for treatment strategies and tailored follow-ups to decrease/prevent recurrence.
    METHODS: The authors performed a comprehensive and detailed systematic literature review of the EMBASE and MEDLINE electronic online databases regarding the topographic pattern of recurrence after surgical treatment for intracranial meningiomas. Demographics and histopathological, neuroradiological and treatment data, pertinent to the topography of recurrences, as well as time to recurrences, were extracted and analyzed.
    RESULTS: Four studies, including 164 cases of recurrences according to the inclusion criteria, were identified. All studies consider the possibility of recurrence at the previous dural site; three out of four, which are the most recent, consider 1 cm outside the previous dural margin to be the main limit to distinguish recurrences closer to the previous site from those more distant. Recurrences mainly occur within or close to the surgical bed; higher values of proliferation index are associated with recurrences close to the original site rather than within it.
    CONCLUSIONS: Further studies, including genomic characterization of different patterns of recurrence, will better clarify the main features affecting the topography of recurrences. A comparison between topographic classifications of intracranial meningioma recurrences after surgery and after radiation treatment could provide further interesting information.

    这项范围审查的目的是评估磁共振成像(MRI)的潜力,并确定文献中报道的哪些可用的MRI技术最有希望评估新辅助放疗(NRT)后乳腺癌患者的治疗反应。OvidMedline,Embase,CINAHL,和Cochrane数据库进行了搜索,以确定从开始到2023年3月13日发表的相关研究。在主要选择之后,2名评审员使用标准化的数据提取模板对每项研究进行了评估,以设定的纳入和排除标准为指导。总共选择了5个符合条件的研究。MRI预测病理完全缓解的阳性和阴性预测值在研究中分别为67%至88%和76%至85%。分别。MRI在评估放疗后肿瘤大小方面的潜力在体积测量方面比在一维最长直径测量方面更大;然而,观察到手术肿瘤大小的高估。观察到表观扩散系数(ADC)值和增强时间(TTE)在NRT后增加,在6个月时,响应者和无响应者之间存在显着差异,表明在评估治疗反应方面的潜在作用。总之,这篇综述强调了肿瘤体积的测量,ADC,和TTE作为评估乳腺癌NRT后治疗反应的有前途的MRI指标。然而,需要对更大的队列进行进一步的研究,以确认它们的效用。如果MRI能准确地从NRT的无应答者中识别出应答者,它可以实现更个性化和量身定制的治疗方法,潜在的减少放射治疗相关的毒性和提高美容效果。
    The objective of this scoping review is to evaluate the potential of Magnetic Resonance Imaging (MRI) and to determine which of the available MRI techniques reported in the literature are the most promising for assessing treatment response in breast cancer patients following neoadjuvant radiotherapy (NRT). Ovid Medline, Embase, CINAHL, and Cochrane databases were searched to identify relevant studies published from inception until March 13, 2023. After primary selection, 2 reviewers evaluated each study using a standardized data extraction template, guided by set inclusion and exclusion criteria. A total of 5 eligible studies were selected. The positive and negative predictive values for MRI predicting pathological complete response across the studies were 67% to 88% and 76% to 85%, respectively. MRI\'s potential in assessing postradiotherapy tumor sizes was greater for volume measurements than uni-dimensional longest diameter measurements; however, overestimation in surgical tumor sizes was observed. Apparent diffusion coefficient (ADC) values and Time to Enhance (TTE) was seen to increase post-NRT, with a notable difference between responders and nonresponders at 6 months, indicating a potential role in assessing treatment response. In conclusion, this review highlights tumor volume measurements, ADC, and TTE as promising MRI metrics for assessing treatment response post-NRT in breast cancer. However, further research with larger cohorts is needed to confirm their utility. If MRI can accurately identify responders from nonresponders to NRT, it could enable a more personalized and tailored treatment approach, potentially minimizing radiation therapy related toxicity and enhancing cosmetic outcomes.

    脑膜转移越来越被认为是可治疗的,但通常无法治愈,晚期癌症的并发症。由于现代癌症疗法延长了转移性癌症患者的生命,特别是在脑实质转移患者中,实体瘤软脑膜转移患者的治疗选择和临床研究方案也得到了类似的发展,以提高特定人群的生存率。最近临床研究的扩展,早期诊断,和药物开发引发了新的悬而未决的问题。这些包括软脑膜转移生物学和首选的动物模型,现代癌症人群的流行病学,确保新的软脑膜转移诊断的验证和可及性,多模式治疗方案的最佳临床实践,临床试验设计和反应评估标准化,以及值得进一步研究的途径。一个由多学科专家组成的国际小组,研究和管理软脑膜转移,由神经肿瘤学会和美国临床肿瘤学会支持,他们聚集在一起,就这些紧迫的话题达成共识,并为未来的方向提供路线图。我们希望这些建议将加速软脑膜转移领域的合作和进展,并作为进一步讨论和患者倡导的平台。
    Leptomeningeal metastases are increasingly becoming recognized as a treatable, yet generally incurable, complication of advanced cancer. As modern cancer therapeutics have prolonged the lives of patients with metastatic cancer, specifically in patients with parenchymal brain metastases, treatment options and clinical research protocols for patients with leptomeningeal metastases from solid tumors have similarly evolved to improve survival within specific populations. Recent expansion in clinical investigation, early diagnosis, and drug development have given rise to new unanswered questions. These include leptomeningeal metastasis biology and preferred animal modeling, epidemiology in the modern cancer population, ensuring validation and accessibility of newer leptomeningeal metastasis diagnostics, best clinical practices with multi-modality treatment options, clinical trial design and standardization of response assessments, and avenues worthy of further research. An international group of multi-disciplinary experts in the research and management of leptomeningeal metastases, supported by the Society for Neuro-Oncology and American Society of Clinical Oncology, were assembled to reach a consensus opinion on these pressing topics and provide a roadmap for future directions. Our hope is that these recommendations will accelerate collaboration and progress in the field of leptomeningeal metastases and serve as a platform for further discussion and patient advocacy.

    了解接受头颈部辐射的患者的预防性吞咽和三联肌锻炼的障碍和促进因素可能有助于锻炼依从性。该分析审查了所有已发布的运动依从性报告,并根据PRISMA指南进行了严格评估。共确定了137篇潜在论文;20项研究符合纳入标准。最常报道的吞咽和牙关练习的促进者是定期的临床医生联系和在线资源,以加强指导,设定目标,管理辐射毒性。据报道,社会支持和锻炼带来的好处也有所帮助。运动最常见的障碍是辐射毒性,焦虑,感觉被信息淹没了,不理解练习的原因。在为接受头颈部癌症放射治疗的患者设计运动干预措施时,了解促进者和依从性障碍至关重要。
    Understanding the barriers and facilitators for prophylactic swallowing and trismus exercises for patients undergoing radiation to the head and neck may help exercise adherence. The analysis reviews all published reports of exercise adherence with a critical appraisal following PRISMA guidelines. A total of 137 potential papers were identified; 20 studies met the inclusion criteria. The most commonly reported facilitators for swallowing and trismus exercises were regular clinician contact and online resources to reinforce instructions, set goals, and manage radiation toxicities. Social support and perceived benefit from exercises were also reported to be of help. The most common barriers to exercise were radiation toxicities, anxiety, feeling overwhelmed with information, and not understanding the reason for the exercises. Understanding facilitators and barriers to adherence is critical when designing exercise interventions for patients undergoing radiation for head and neck cancer.

    乳房切除术后的乳房再造(BR)对于女性的身体形象增强和心理健康很重要。尽管乳房切除术后放疗(PMRT)显着改善了高危乳腺癌(BC)患者的预后,BR后的PMRT可能会影响美容效果,并可能损害改善生活质量(QoL)的原始目标。由于缺乏实用的指导方针,似乎有必要达成共识并提供一些“专家协议”,为患者提供BR后PMRT的最佳选择。我们报告了一项全球“专家协议”,该协议是在2023年3月举行的第六届国际多学科乳腺会议上对BR和PMRT文献进行严格审查的结果。
    Breast reconstruction (BR) after mastectomy is important to consider for a woman\'s body image enhancement and psychological well-being. Although post-mastectomy radiation (PMRT) significantly improves the outcome of patients with high-risk breast cancer (BC), PMRT after BR may affect cosmetic outcomes and may compromise the original goal of improving quality of life (QoL). With the lack of practical guidelines, it seems essential to work on a consensus and provide some \"expert agreements\" to offer patients the best option for PMRT after BR. We report a global \"expert agreement\" that results from a critical review of the literature on BR and PMRT during the 6th international multidisciplinary breast conference in March 2023.

    目的:目前对局限性前列腺癌(PCa)的治疗选择包括根治性前列腺切除术(RP),放射治疗(RT),主动监测(AS)。尽管肿瘤结果相当,在患者报告的结局指标(PROM)和患者报告的经验指标(PREM)方面,仍缺乏证据证明它们的相对有效性.我们对比较PROM和PREM的研究进行了系统回顾,在所有推荐的本地化PCa管理选项之后(RP,RT,AS).
    方法:在MEDLINE中进行了文献检索,EMBASE,和CochraneCENTRAL数据库符合欧洲泌尿外科协会指南办公室的建议以及系统审查和荟萃分析声明的首选报告项目。包括所有报告PROM和/或PREM以比较RP与RT与AS的前瞻性临床试验。使用叙述性综合来总结综述结果。由于现有研究的异质性和局限性,没有进行定量合成。
    我们的研究结果表明,RP主要影响尿失禁和性功能,与其他治疗相比,排尿症状效果更好。RT与肠功能和排尿症状的更大损害相关。这些治疗方法均未对精神或身体生活质量产生重大影响。只有少数研究报告了PREM,所有模式的决策后悔率都很高(高达23%)。
    结论:所有推荐的局部PCa治疗对PROM和PREM都有影响,但对于不同的领域和不同的严重性。我们在PROM收集中发现了显著的异质性,因此,在现实世界的实践和临床试验的标准化是必要的。只有少数研究报告了PREM,强调一个未满足的需求,应该在未来的研究中探讨。
    结果:我们回顾了手术切除前列腺后患者报告的结果和经验的差异,放射治疗,或者主动监测前列腺癌.我们发现对泌尿的影响不同,肠,和治疗中的性功能,但精神或身体生活质量没有区别。我们的结果可以帮助医生和前列腺癌患者共同决策。
    OBJECTIVE: Current management options for localized prostate cancer (PCa) include radical prostatectomy (RP), radiotherapy (RT), and active surveillance (AS). Despite comparable oncological outcomes, there is still lack of evidence on their comparative effectiveness in terms of patient-reported outcome measures (PROMs) and patient-reported experience measures (PREMs). We conducted a systematic review of studies comparing PROMs and PREMs after all recommended management options for localized PCa (RP, RT, AS).
    METHODS: A literature search was performed in the MEDLINE, EMBASE, and Cochrane CENTRAL databases in accordance with recommendations from the European Association of Urology Guidelines Office and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. All prospective clinical trials reporting PROMs and/or PREMs for comparisons of RP versus RT versus AS were included. A narrative synthesis was used to summarize the review findings. No quantitative synthesis was performed because of the heterogeneity and limitations of the studies available.
    UNASSIGNED: Our findings reveal that RP mostly affects urinary continence and sexual function, with better results for voiding symptoms in comparison to other treatments. RT was associated with greater impairment of bowel function and voiding symptoms. None of the treatments had a significant impact on mental or physical quality of life. Only a few studies reported PREMs, with a high rate of decision regret for all modalities (up to 23%).
    CONCLUSIONS: All recommended treatments for localized PCa have an impact on PROMs and PREMs, but for different domains and with differing severity. We found significant heterogeneity in PROM collection, so standardization in real-world practice and clinical trials is warranted. Only a few studies have reported PREMs, highlighting an unmet need that should be explored in future studies.
    RESULTS: We reviewed differences in patient reports of their outcomes and experiences after surgical prostate removal, radiotherapy, or active surveillance for prostate cancer. We found differences in the effects on urinary, bowel, and sexual functions among the treatments, but no difference for mental or physical quality of life. Our results can help doctors and prostate cancer patients in shared decision-making.

    代表第二常见的皮肤癌,皮肤鳞状细胞癌(cSCC)的发病率和疾病负担持续增加.原发部位的手术切除可有效治愈大多数cSCC病例。然而,cSCC的侵袭性子集持续存在临床病理特征,表明复发较高,转移,和死亡风险。这些特征的加速是由遗传和环境因素的组合驱动的。在过去的几年中,在塑造高级cSCC的治疗环境方面取得了显着进展。风险分层和临床管理是当务之急。这篇综述概述了当前关于cSCC的观点,重点是分期,治疗,和维护策略,以及未来的研究方向。
    Representing the second most common skin cancer, the incidence and disease burden of cutaneous squamous cell carcinoma (cSCC) continues to increase. Surgical excision of the primary site effectively cures the majority of cSCC cases. However, an aggressive subset of cSCC persists with clinicopathological features that are indicative of higher recurrence, metastasis, and mortality risks. Acceleration of these features is driven by a combination of genetic and environmental factors. The past several years have seen remarkable progress in shaping the treatment landscape for advanced cSCC. Risk stratification and clinical management is a top priority. This review provides an overview of the current perspectives on cSCC with a focus on staging, treatment, and maintenance strategies, along with future research directions.

    目的:头颈部腺样囊性癌(HNACC)是一种耐放射性肿瘤。粒子疗法,主要是质子束治疗和碳离子辐射,是一种潜在的放射治疗抗放射性恶性肿瘤。本研究旨在进行荟萃分析,以评估带电粒子放射治疗对HNACC的影响。方法:在Pubmed,科克伦图书馆,WebofScience,Embase,和Medline直到2022年12月31日。主要终点是总生存期(OS),本地控制(LC),和无进展生存期(PFS),而次要结局包括治疗相关毒性.STATA的17.0版用于所有分析。结果:共14项研究,涉及1297名患者,包括在分析中。原发性HNACC的合并5年OS和PFS率为78%(95%置信区间[CI]=66-91%)和62%(95%CI=47-77%),分别。对于所有包括在内的患者,合并的2年和5年操作系统,LC,和PFS率如下:86.1%(95%CI=95-100%)和77%(95%CI=73-82%),92%(95%CI=84-100%)和73%(95%CI=61-85%),76%(95%CI=68-84%)和55%(95%CI=48-62%),分别。3级及以上急性毒性率为22%(95%CI=13-32%),而晚期毒性率为8%(95%CI=3-13%)。结论:颗粒疗法有可能改善HNACC患者的治疗结果并提高其生活质量。然而,由于与这种治疗方式相关的可用性和成本考虑有限,因此需要进一步研究和优化.
    Purpose: Head and neck adenoid cystic carcinoma (HNACC) is a radioresistant tumor. Particle therapy, primarily proton beam therapy and carbon-ion radiation, is a potential radiotherapy treatment for radioresistant malignancies. This study aims to conduct a meta-analysis to evaluate the impact of charged particle radiation therapy on HNACC. Methods: A comprehensive search was conducted in Pubmed, Cochrane Library, Web of Science, Embase, and Medline until December 31, 2022. The primary endpoints were overall survival (OS), local control (LC), and progression-free survival (PFS), while secondary outcomes included treatment-related toxicity. Version 17.0 of STATA was used for all analyses. Results: A total of 14 studies, involving 1297 patients, were included in the analysis. The pooled 5-year OS and PFS rates for primary HNACC were 78% (95% confidence interval [CI] = 66-91%) and 62% (95% CI = 47-77%), respectively. For all patients included, the pooled 2-year and 5-year OS, LC, and PFS rates were as follows: 86.1% (95% CI = 95-100%) and 77% (95% CI = 73-82%), 92% (95% CI = 84-100%) and 73% (95% CI = 61-85%), and 76% (95% CI = 68-84%) and 55% (95% CI = 48-62%), respectively. The rates of grade 3 and above acute toxicity were 22% (95% CI = 13-32%), while late toxicity rates were 8% (95% CI = 3-13%). Conclusions: Particle therapy has the potential to improve treatment outcomes and raise the quality of life for HNACC patients. However, further research and optimization are needed due to the limited availability and cost considerations associated with this treatment modality.
