Aims

Paediatric high-grade gliomas (pedHGGs) have a dismal prognosis, often characterised by early and diffuse disease progression. Novel treatment approaches are urgently needed to improve outcomes. The upcoming SIOPE-HGG (High Grade Glioma)-01 trial will investigate upfront craniospinal radiochemotherapy (CSI-RCT) for newly diagnosed, nonmetastatic diffuse midline glioma/diffuse intrinsic pontine glioma (DMG/DIPG). As CSI-RCT is frequently avoided due to concerns over haematotoxicity, real-world feasibility data are critically needed.

Materials and methods

We retrospectively assessed haematological toxicity in 19 patients (aged 3-21 years) with metastatic pedHGG treated with CSI-RCT within the hirn tumor glioblastoma trial (HIT-HGG) and hospital in trial-glioblastoma (HIT-GBM) trial programmes (2002–2024). All patients received craniospinal irradiation (median dose: 35.2 Gy) using photon- or proton-based techniques, with concurrent chemotherapy: temozolomide (TMZ; n = 14) or PEI (cisplatin, etoposide, ifosfamide; n = 5). Haematological toxicities were graded according to Common Terminology Criteria for Adverse Events (CTCAE) v4.0.

Results

Grade 3 to 4 haematotoxicity was observed in 7 of 19 patients (36.8%). Chemotherapy was discontinued in two cases—one due to TMZ-induced aplastic anaemia (TIAA) and another due to thrombocytopaenia. The remaining patients tolerated full-dose CSI-RCT with manageable side effects, and no unplanned radiotherapy interruptions occurred. The haematotoxicity rate was comparable to or lower than previous reports, indicating that CSI-RCT is feasible with appropriate monitoring and management.

Conclusion

This is the largest cohort to date assessing haematological toxicity of upfront CSI-RCT in metastatic pedHGG. Despite notable haematotoxicity, treatment was largely feasible and well-tolerated. These findings support the integration of CSI-RCT into future clinical trials for newly diagnosed DMG/DIPG and provide a foundation for the upcoming SIOPE HGG-01 trial. Proton therapy may further reduce toxicity and warrants prospective evaluation.
目的:儿童高级别胶质瘤(pedHGGs)预后不佳,通常以早期和弥漫性疾病进展为特征。迫切需要新的治疗方法来改善结果。即将进行的siop - hgg (High Grade Glioma)-01试验将研究新诊断的非转移性弥漫性中线胶质瘤/弥漫性固有脑桥胶质瘤(DMG/DIPG)的颅脊髓放化疗(CSI-RCT)。由于担心血液毒性,CSI-RCT经常被避免,因此迫切需要真实世界的可行性数据。材料和方法我们回顾性评估了19例(3-21岁)转移性pedHGG患者的血液学毒性,这些患者接受了ct - rct治疗,这些患者来自于恶性肿瘤胶质母细胞瘤试验(HIT-HGG)和医院试验-胶质母细胞瘤(HIT-GBM)试验项目(2002-2024)。所有患者均接受了基于光子或质子技术的颅脊髓照射(中位剂量:35.2 Gy),同时化疗:替莫唑胺(TMZ, n = 14)或PEI(顺铂、依托泊苷、异环磷酰胺,n = 5)。血液学毒性根据不良事件通用术语标准(CTCAE) v4.0进行分级。结果19例患者中有7例(36.8%)出现3 ~ 4级血液毒性。2例患者停止化疗,1例因tmz诱导再生障碍性贫血(TIAA),另1例因血小板减少症。其余患者耐受全剂量CSI-RCT,副作用可控,未发生计划外放疗中断。血液毒性率与以前的报告相当或更低,表明CSI-RCT在适当的监测和管理下是可行的。这是迄今为止评估转移性pedHGG的先期CSI-RCT血液学毒性的最大队列。尽管有明显的血液毒性,但治疗在很大程度上是可行的,并且耐受性良好。这些发现支持将CSI-RCT整合到未来新诊断DMG/DIPG的临床试验中,并为即将进行的SIOPE HGG-01试验提供基础。质子治疗可进一步降低毒性,值得进行前瞻性评价。

Aims

To introduce a Biological Adaptive Radiotherapy (BART) framework that incorporates biological effects into adaptive planning, quantify the impact of a short intrafraction interruption on biologically effective dose (BED) in stage III non-small cell lung cancer treated with volumetric modulated arc therapy (VMAT), and evaluate a compensation strategy designed to restore target BED while respecting organs-at-risk (OAR) constraints.

Methods

We analysed lung non-small cell cancer patients with stage III treated using VMAT with two full arcs. A microdosimetric kinetic model (MKM) was used to calculate BED reductions caused by a 120-minute interruption after the first arc. Compensation plans were generated by converting deviations in biological dose into physical dose adjustments, which were optimised using a treatment planning system (TPS). Dose–volume histograms (DVHs) and other metrics were compared for plans with and without interruptions and after BART compensation.

Results

Interruption An interruption caused BED reductions in planning target volume, with the dose difference of the D98% and D2% differences of 15.7%-16.5% and 5.2%-14.5%, respectively. For a normal lung, volume differences at 5 Gy (V5Gy) and 20 Gy (V20Gy) ranged from 0.7% to 2.2% and 0.3% to 4.7%, respectively. With dose compensation, the dose differences reduced to 0.8%-1.4% for the D98% and 1.4%-8.3% for the D2%. The difference of the V5Gy and V20Gy also decreased to 1.0%-4.1% and 0.4%-2.6%, respectively. Spinal cord dose constraints were met across all plans.

Conclusion

The BART framework effectively compensates for BED reductions due to short-term treatment interruptions, preserving therapeutic efficacy and adhering to organ at risk (OAR) constraints. This innovative approach represents a transformative advancement in adaptive radiation therapy by integrating biological considerations, enhancing treatment precision and personalisation.
目的:引入生物适应性放疗(BART)框架,将生物效应纳入适应性规划,量化短时间内抽吸中断对III期非小细胞肺癌体积调节电弧治疗(VMAT)的生物有效剂量(BED)的影响,并评估旨在恢复靶BED的补偿策略,同时尊重危险器官(OAR)限制。方法:我们分析了使用VMAT治疗的肺非小细胞癌III期患者。微剂量动力学模型(MKM)用于计算第一次电弧后120分钟中断引起的BED减少。补偿计划是通过将生物剂量偏差转换为物理剂量调整来生成的,并使用治疗计划系统(TPS)对其进行优化。剂量-体积直方图(DVHs)和其他指标在有中断和没有中断以及BART补偿后的计划中进行了比较。中断使BED计划靶体积减小,D98%和D2%的剂量差异分别为15.7% ~ 16.5%和5.2% ~ 14.5%。正常肺在5gy (V5Gy)和20gy (V20Gy)下的体积差异分别为0.7% ~ 2.2%和0.3% ~ 4.7%。剂量补偿后,D98%组和D2%组的剂量差异分别降至0.8% ~ 1.4%和1.4% ~ 8.3%。V5Gy和V20Gy的差异也分别减小到1.0% ~ 4.1%和0.4% ~ 2.6%。所有计划均满足脊髓剂量限制。结论:BART框架有效地补偿了由于短期治疗中断而导致的BED减少,保持了治疗效果并遵守了危险器官(OAR)的限制。这种创新的方法通过整合生物学因素,提高治疗精度和个性化,代表了适应性放射治疗的变革性进步。

Aims

The aim of this study was to describe the clinical outcomes, demographics, and clinical characteristics of patients with locally advanced, unresectable, stage III non–small cell lung cancer (NSCLC) treated with durvalumab as part of the UK early access programme or post reimbursement.

Materials and methods

CODAK (NCT04667312) was a multicentre, noninterventional, cohort study of patients (N = 114) with locally advanced, unresectable, stage III NSCLC initiated on durvalumab between 1 September 2017 and 31 December 2019 following concurrent or sequential chemoradiotherapy (CRT) in the UK, with retrospective data collection from 10 clinical centres. The primary outcome was the real-world overall survival (rwOS) rate at 12 and 24 months post durvalumab initiation.

Results

Of the 114 patients included, 47 (41.2%) were aged ≥70 years and 67 (58.7%) were male. Median follow-up time from durvalumab initiation was 22 months. The 12-month rwOS rate was 80.2% (95% confidence interval [CI]: 73.1-88.0), and the 24-month rate was 63.0% (54.1-73.4). Median rwOS was 35.9 months (95% CI: 35.9 to not reached [NR]) in the overall cohort. Before durvalumab initiation, 85.1% (97/114) received concurrent CRT and 13.2% (15/114) received sequential CRT (two unknown). In the overall cohort, median real-world progression-free survival was 28.5 months (95% CI: 16.4-NR). The median time to durvalumcab treatment discontinuation was 8.7 months (95% CI: 6.2-11.2). Thirty-three patients (28.9%) discontinued durvalumab treatment due to adverse events (AEs). Pneumonitis/interstitial lung disease (ILD) was the most common AE leading to discontinuation among all patients (19/114 [16.7%]). Eleven patients (9.6%) had at least one interruption due to pneumonitis/ILD.

Conclusion

CODAK provides data from the UK that add to real-world evidence showing that durvalumab following CRT is an effective standard of care for patients with unresectable, stage III NSCLC.
本研究的目的是描述局部晚期,不可切除的III期非小细胞肺癌(NSCLC)患者的临床结果,人口统计学和临床特征,作为英国早期准入计划或后报销计划的一部分,durvalumab治疗。scodak (NCT04667312)是一项多中心、非介入性队列研究,研究对象为2017年9月1日至2019年12月31日期间在英国接受同步或顺序放化疗(CRT)后开始使用durvalumab治疗的局部晚期、不可切除的III期NSCLC患者(N = 114),回顾性收集了来自10个临床中心的数据。主要终点是杜伐单抗开始治疗后12个月和24个月的真实总生存率(rwOS)。结果114例患者中,年龄≥70岁的47例(41.2%),男性67例(58.7%)。durvalumab起始的中位随访时间为22个月。12个月rwOS率为80.2%(95%可信区间[CI]: 73.1 ~ 88.0), 24个月rwOS率为63.0%(54.1 ~ 73.4)。在整个队列中,中位生存期为35.9个月(95% CI: 35.9至未达到[NR])。在durvalumab起始治疗前,85.1%(97/114)接受并行CRT, 13.2%(15/114)接受序贯CRT(2例未知)。在整个队列中,实际无进展生存期中位数为28.5个月(95% CI: 16.4-NR)。杜伐单抗停止治疗的中位时间为8.7个月(95% CI: 6.2-11.2)。33名患者(28.9%)因不良事件(ae)停止了杜伐单抗治疗。肺炎/间质性肺疾病(ILD)是导致所有患者停药的最常见AE(19/114[16.7%])。11名患者(9.6%)因肺炎/ILD至少有一次中断。结论:codak提供的来自英国的数据增加了现实世界的证据,表明durvalumab在CRT后是不可切除的III期NSCLC患者的有效标准护理。

Aims

The integration of cyclin-dependent kinase 4/6 (CDK4/6) inhibitors into the treatment regimen for advanced breast cancer (BC), specifically oestrogen receptor–positive (ER+) subtypes, marks a significant stride in oncological therapy. These inhibitors have demonstrated substantial clinical benefits and are generally well tolerated compared to other targeted therapies. Our study evaluated the effects of dosage reductions on progression-free survival (PFS) and overall survival (OS) in patients undergoing CDK4/6 inhibitor therapy.

Materials and Methods

We conducted an exhaustive literature review across several databases, including PubMed, Embase, and Cochrane, considering studies published up to September 30, 2023. The selection criteria were based on the Patients Interventions Comparisons Outcomes (PICOS) framework, focussing on studies involving ER+ BC patients treated with CDK4/6 inhibitors in combination with endocrine therapy. Both retrospective and prospective studies were included involving adult patients treated with standard doses of CDK4/6 inhibitors for approved indications.

Results

The systematic review included 33 retrospective studies and one phase 2 study, encompassing 7,767 patients. Analysis revealed significant improvements in both OS (hazard ratio [HR] = 0.75, 95% confidence interval [CI]: 0.61-0.93; P < .01) and PFS (HR = 0.87, 95% CI: 0.76-0.98; P = .02) among patients who underwent dosage reduction. The data exhibited low heterogeneity across studies, strengthening the reliability of our findings.

Conclusion

Our research provides valuable insights into the dosage optimisation of CDK4/6 inhibitors and its impact on patient outcomes.

Aims

The use of stereotactic radiosurgery (SRS) to treat patients with intracranial metastatic disease is increasing. Despite efforts to standardise practice across the centres delivering SRS in the UK, evidence suggests that patient selection, treatment volumes, and clinical practice vary significantly. This study aimed to understand the current SRS service provision and identify challenges to support more consistent, high-quality care.

Materials and methods

In 2023, the Tessa Jowell Academy SRS working group distributed a national survey to centres delivering SRS for brain metastases. The survey covered service configuration, treatment protocols, imaging practices, and challenges. Responses were collected from October 2023 to March 2024, with 20 centres participating (17 in England, two in Scotland, and one in Wales).

Results

Substantial variation was reported in service size and delivery. Weekly SRS multidisciplinary team caseloads ranged 3 to 25 patients, and referral rates (adjusted to catchment area) varied five-fold. Most centres used Linac systems (n = 15), followed by Gamma Knife (n = 4) and Cyberknife (n = 3); only two centres had multiple machine types. Six of the 20 centres (30%) referred patients externally, mainly for Gamma Knife treatment. Treatment criteria varied widely: centres treated from ≤5 to >50 lesions, with maximum treated volumes for a single fraction varying substantially. The time from imaging to treatment ranged from within the same day to within two weeks. Variation was also noted in approaches to radionecrosis imaging, treatment margins, and steroid use.
The key challenges reported included workforce capacity (reported by 50% of centres), imaging access (40%), and inappropriate referrals (15%). Encouragingly, five centres (25%) reported no major barriers to service delivery.

Conclusion

The findings highlight a significant variation in SRS practice across the UK. The Tessa Jowell Academy will use these insights to promote standardisation, support clinical teams, and reduce unwarranted variation—ensuring equitable access to high-quality SRS for patients with brain metastases.
目的立体定向放射外科(SRS)治疗颅内转移性疾病的应用越来越多。尽管在英国各个提供SRS的中心努力使实践标准化,但有证据表明,患者选择、治疗量和临床实践差异很大。本研究旨在了解当前SRS服务的提供,并确定支持更一致、高质量护理的挑战。材料和方法2023年,Tessa Jowell学院SRS工作组向提供脑转移SRS的中心分发了一项全国性调查。调查涵盖了服务配置、治疗方案、成像实践和挑战。从2023年10月到2024年3月,共有20个中心参与调查(17个在英格兰,2个在苏格兰,1个在威尔士)。结果在服务规模和交付方面报告了实质性的变化。每周SRS多学科小组病例量为3至25例,转诊率(根据集水区调整)变化了5倍。大多数中心使用直线系统(n = 15),其次是伽玛刀(n = 4)和射波刀(n = 3);只有两个中心有多种机器类型。20个中心中有6个(30%)将患者转介到外部,主要是进行伽玛刀治疗。治疗标准差异很大:治疗中心从≤5到50个病变,单个部分的最大治疗体积差异很大。从成像到治疗的时间从同一天到两周不等。在放射性坏死成像方法、治疗范围和类固醇使用方面也存在差异。报告的主要挑战包括劳动力能力(50%的中心报告),成像访问(40%)和不适当的转诊(15%)。令人鼓舞的是,五个中心(25%)报告在提供服务方面没有重大障碍。结论:研究结果强调了英国各地SRS实践的显著差异。Tessa Jowell学院将利用这些见解来促进标准化,支持临床团队,减少不必要的变化,确保脑转移患者公平获得高质量的SRS。

Aims

To evaluate whether BRAFV600E mutation status enhances the value of age in predicting clinical outcomes for papillary thyroid carcinoma (PTC) patients receiving radioactive iodide (RAI) therapy.

Materials and methods

We conducted a retrospective analysis of 1160 PTC patients treated with RAI therapy. Patients were stratified by age (≤18, 18-55, and ≥55 years) and BRAFV600E status. Clinicopathological characteristics, treatment responses, and risk factors for poor outcomes (biochemical/structural incomplete response biochemical incomplete response/structural incomplete response [BIR/SIR]) were analysed using logistic regression.

Results

BRAFV600E-positive patients aged ≤18 years showed aggressive features, including larger tumour size, higher lymph node metastasis rates, elevated thyroglobulin levels (TgAb-negative), and worse 6-month/3-year outcomes (all P < .05). Multivariate analysis confirmed high-risk subtypes, distant metastasis, and elevated Tg levels as independent BIR/SIR predictors. BRAFV600E-negative patients showed no significant age-related clinical characteristics and outcomes (P > .05).

Conclusion

BRAFV600E mutation status significantly modifies the impact of age in PTC patients with RAI therapy. Patients aged ≤18 years with BRAFV600E-positive exhibit distinct aggressive behaviours and poorer RAI therapy responses. These findings support integrating BRAFV600E testing with age stratification to refine risk assessment and therapeutic strategies.
目的评价BRAFV600E突变状态是否增强了年龄在预测接受放射性碘化物(RAI)治疗的甲状腺乳头状癌(PTC)患者临床预后中的价值。材料与方法我们对1160例接受RAI治疗的PTC患者进行回顾性分析。患者按年龄(≤18岁、18-55岁和≥55岁)和BRAFV600E状态进行分层。采用logistic回归分析临床病理特征、治疗反应和不良结局的危险因素(生化/结构不完全缓解生化不完全缓解/结构不完全缓解[BIR/SIR])。结果≤18岁brafv600e阳性患者表现为肿瘤体积较大、淋巴结转移率较高、甲状腺球蛋白水平升高(tgab阴性)、6个月/3年预后较差(P < 0.05)。多因素分析证实高危亚型、远处转移和Tg水平升高是独立的BIR/SIR预测因子。brafv600e阴性患者无明显的年龄相关临床特征和结局(P > 0.05)。结论brafv600e突变状态显著改变年龄对RAI治疗PTC患者的影响。年龄≤18岁的brafv600e阳性患者表现出明显的攻击行为和较差的RAI治疗反应。这些发现支持将BRAFV600E检测与年龄分层相结合,以完善风险评估和治疗策略。

Aims

Precision oncology, driven by next-generation sequencing (NGS), enables the use of matched targeted therapies (MTTs) tailored to tumour-specific genomic alterations. While benefits in early-stage cancer are well-established, the impact of MTTs in relapsed or metastatic settings remains unclear. This systematic review and meta-analysis (PROSPERO ID: CRD42023471466) evaluates the efficacy and safety of NGS-guided MTTs in patients with advanced solid and haematological tumours.

Materials and methods

Searches of CENTRAL, MEDLINE, EMBASE (to 30 October 2024), reference lists, and conference proceedings identified randomized controlled trials (RCTs) comparing NGS-guided MTTs (alone or combined with standard of care systemic treatment [SOC]) versus SOC alone in patients with advanced cancers that had progressed after at least one prior systemic therapy. Primary outcomes were progression-free survival (PFS), overall survival (OS), and grade ≥3 adverse events. Data extraction and bias assessment were conducted independently by two reviewers. Random-effects meta-analysis was performed using the DerSimonian-Laird method.

Results

Thirty RCTs (7393 patients) were included that collectively enrolled patients with eight different cancer types. With a median follow-up ranging from 12 months to 62.3 months, MTTs were associated with a 30–40% reduction in the risk of disease progression. No consistent OS benefit was observed with MTT monotherapy. However, combining MTTs with SOC resulted in improved OS, particularly in patients with prostate and urothelial cancer, but conferred PFS gain without OS improvement in those with breast and ovarian cancer. In terms of adverse events, we observed MTTs increased toxicity risk compared to SOC, specifically, in combination regimens. Most studies were at high risk of bias, with performance and detection bias being common limitations.

Conclusion

NGS-guided MTTs significantly enhance PFS, especially when combined with SOC, with OS benefits being more tumour-specific. Increased toxicity rates with MTTs underscore the need for careful in patient selection. Furthermore, genomic profiling should be routinely integrated into the management of patients with advanced or recurrent cancers.
目的:在下一代测序(NGS)的推动下,精确肿瘤学能够使用针对肿瘤特异性基因组改变的匹配靶向治疗(MTTs)。虽然对早期癌症的益处是公认的,但mtt对复发或转移性癌症的影响仍不清楚。这项系统综述和荟萃分析(PROSPERO ID: CRD42023471466)评估了ngs引导的mtt治疗晚期实体和血液肿瘤患者的疗效和安全性。材料和方法:检索CENTRAL, MEDLINE, EMBASE(至2024年10月30日),参考文献列表和会议记录,确定了随机对照试验(rct),比较ngs引导的MTTs(单独或联合标准护理系统治疗[SOC])与单独SOC在至少一次既往系统治疗后进展的晚期癌症患者中的疗效。主要结局是无进展生存期(PFS)、总生存期(OS)和≥3级不良事件。数据提取和偏倚评估由两名审稿人独立进行。随机效应荟萃分析采用dersimonan - laird方法。结果:共纳入30项随机对照试验(7393例患者),共纳入8种不同癌症类型的患者。中位随访时间为12个月至62.3个月,mtt与疾病进展风险降低30-40%相关。MTT单药治疗未观察到一致的OS获益。然而,mtt联合SOC改善了OS,特别是前列腺癌和尿路上皮癌患者,但在乳腺癌和卵巢癌患者中,PFS增加而OS没有改善。在不良事件方面,我们观察到与SOC相比,mtt增加了毒性风险,特别是在联合方案中。大多数研究存在高偏倚风险,性能和检测偏倚是常见的局限性。结论:ngs引导的mtt可显著提高PFS,特别是与SOC联合使用时,OS获益更具肿瘤特异性。mtt的毒性增加强调了谨慎选择患者的必要性。此外,基因组分析应常规纳入晚期或复发癌症患者的管理。
