CT Densitometry and Morphology of Radiofrequency-Ablated Stage IA Non–Small Cell Lung Cancer: Results from the American College of Surgeons Oncology Group Z4033 (Alliance) Trial

PurposeTo evaluate tumor and ablation zone morphology and densitometry related to tumor recurrence in participants with Stage IA non–small cell lung cancer undergoing radiofrequency ablation in a prospective, multicenter trial.Materials and MethodsForty-five participants (median 76 years old; 25 women; 20 men) from 16 sites were followed for 2 years (December 2006 to November 2010) with computed tomography (CT) densitometry. Imaging findings before and after ablation were recorded, including maximum CT attenuation (in Hounsfield units) at precontrast and 45-, 90-, 180-, and 300-s postcontrast.ResultsEvery 1-cm increase in the largest axial diameter of the ablation zone at 3-months’ follow-up compared to the index tumor reduced the odds of 2-year recurrence by 52% (P = .02). A 1-cm difference performed the best (sensitivity, 0.56; specificity, 0.93; positive likelihood ratio of 8). CT densitometry precontrast and at 45 seconds showed significantly different enhancement patterns in a comparison among pretreated lung cancer (delta = +61.2 HU), tumor recurrence (delta = +57 HU), and treated tumor/ablation zone (delta [change in attenuation] = +16.9 HU), (P < .0001). Densitometry from 45 to 300 s was also different among pretreated tumor (delta = −6.8 HU), recurrence (delta = −11.2 HU), and treated tumor (delta = +12.1 HU; P = .01). Untreated and residual tumor demonstrated washout, whereas treated tumor demonstrated increased attenuation.ConclusionsAn ablation zone ≥1 cm larger than the initial tumor, based on 3-month follow-up imaging, is recommended to decrease odds of recurrence. CT densitometry can delineate tumor versus treatment zones.

Outcomes after neoadjuvant or adjuvant chemotherapy for cT2-4N0-1 non–small cell lung cancer: A propensity-matched analysis

Objective

Comparative survival between neoadjuvant chemotherapy and adjuvant chemotherapy for patients with cT2-4N0-1M0 non–small cell lung cancer has not been extensively studied.

Preparing IR for COVID-19: The Singapore Experience

This paper describes country-wide special measures undertaken for interventional radiology staff during the current coronavirus disease 2019 (COVID-19) pandemic. Although each interventional radiology service around the world faces unique challenges, the principles outlined in this article will be useful when designing or strengthening individual practices and integrating them within wider hospital and national measures. Moving beyond the current outbreak, these measures will be useful for any future infectious diseases which are likely to arise.     

Epigenetics explained: a topic “primer” for the epilepsy community by the ILAE Genetics/Epigenetics Task Force

Epigenetics refers broadly to processes that influence medium to long‐term gene expression by changing the readability and accessibility of the genetic code. The Neurobiology Commission of the International League Against Epilepsy (ILAE) recently convened a Task Force to explore and disseminate advances in epigenetics to better understand their role and intersection with genetics and the neurobiology of epilepsies and their co‐morbidities, and to accelerate translation of these findings into the development of better therapies. Here, we provide a topic primer on epigenetics, explaining the key processes and findings to date in experimental and human epilepsy. We review the growing list of genes with epigenetic functions that have been linked with epilepsy in humans. We consider potential practical applications, including using epigenetic signals as biomarkers for tissue‐ and biofluid‐based diagnostics and the prospects for developing epigenetic‐based treatments for epilepsy. We include a glossary of terms, FAQs and other supports to facilitate a broad understanding of the topic for the non‐expert. Last, we review the limitations, research gaps and the next challenges. In summary, epigenetic processes represent important mechanisms controlling the activity of genes, providing opportunities for insight into disease mechanisms, biomarkers and novel therapies for epilepsy.     

HBV-ACLF患者血清miR-122和 HMGB1水平及其与病情、预后的关系

[摘要]　目的　探究HBV相关慢加急性肝衰竭（HBV-related acute-on-chronic liver failure, HBV-ACLF）患者血清中微小核糖核酸（microRNA, miR）-122和高迁移率族蛋白1（high-mobility group box-B1, HMGB1）水平及其与病情、预后的关系。方法　回顾性分析2016年1月—2018年1月我院收治的120例HBV-ACLF患者的一般及临床资料。根据临床结局，将患者分为存活组（53例）和死亡组（67例）。比较2组患者的一般资料、实验室检查指标及血清miR-122、HMGB1水平。多因素Logistic回归分析影响患者预后的因素。Pearson检验分析miR-122、HMGB1水平分别与TBIL、PA、终末期肝病评分模型（the model of end-stage liver disease score, MELD）评分的相关性。ROC曲线分析miR-122和HMGB1水平对患者的死亡预测价值，获得最佳临界值。根据临界值将患者分为A组、B组和C组，用Kaplan-Meier法绘制生存曲线，比较3组患者在3年随访期间的生存率。结果　存活组和死亡组患者的年龄、身体质量指数、并发症、病情分期、MELD评分、ALB、球蛋白、TBIL、ALT、AST、LDH、PT、PTA、HBV DNA、miR-122、HMGB1相比，差异均具有统计学意义（P均＜0.05）。年龄、并发症、病情分期、MELD评分、TBIL、PT、PTA、miR-122、HMGB1均是影响患者预后的危险因素（P均＜0.05）。miR-122、HMGB1水平分别与TBIL、MELD评分呈显著正相关，与PTA呈显著负相关（P均＜0.05）。miR-122和HMGB1预测患者死亡的最佳临界值分别为31.42和14.56 μg/L。A组患者预后3年内生存率显著高于B组和C组（P均＜0.05）。结论　miR-122和HMGB1水平与HBV-ACLF患者的病情和死亡预后密切相关，可间接反映患者的病情严重程度，在HBV-ACLF的诊断及预后中具有重要价值。
