Purpose To develop and validate a machine learning multimodality model based on preoperative MRI, surgical whole-slide imaging (WSI), and clinical variables for predicting prostate cancer (PCa) biochemical recurrence (BCR) following radical prostatectomy (RP). Materials and Methods In this retrospective study (September 2015 to April 2021), 363 male patients with PCa who underwent RP were divided into training (n = 254; median age, 69 years [IQR, 64-74 years]) and testing (n = 109; median age, 70 years [IQR, 65-75 years]) sets at a ratio of 7:3. The primary end point was biochemical recurrence-free survival. The least absolute shrinkage and selection operator Cox algorithm was applied to select independent clinical variables and construct the clinical signature. The radiomics signature and pathomics signature were constructed using preoperative MRI and surgical WSI data, respectively. A multimodality model was constructed by combining the radiomics signature, pathomics signature, and clinical signature. Using Harrell concordance index (C index), the predictive performance of the multimodality model for BCR was assessed and compared with all single-modality models, including the radiomics signature, pathomics signature, and clinical signature. Results Both radiomics and pathomics signatures achieved good performance for BCR prediction (C index: 0.742 and 0.730, respectively) on the testing cohort. The multimodality model exhibited the best predictive performance, with a C index of 0.860 on the testing set, which was significantly higher than all single-modality models (all P ≤ .01). Conclusion The multimodality model effectively predicted BCR following RP in patients with PCa and may therefore provide an emerging and accurate tool to assist postoperative individualized treatment.

目的 开发并验证一种基于术前磁共振成像、手术全切片成像(WSI)和临床变量的机器学习多模态模型,用于预测前列腺癌(PCa)根治性前列腺切除术(RP)后的生化复发(BCR)。材料与方法 在这项回顾性研究中(2015 年 9 月至 2021 年 4 月),363 名接受前列腺癌根治术的男性 PCa 患者按 7:3 的比例被分为训练组(n = 254;中位年龄 69 岁 [IQR 64-74 岁])和测试组(n = 109;中位年龄 70 岁 [IQR 65-75 岁])。主要终点是无生化复发生存期。采用最小绝对收缩和选择算子 Cox 算法选择独立的临床变量并构建临床特征。放射组学特征和病理组学特征分别使用术前 MRI 和手术 WSI 数据构建。结合放射组学特征、病理组学特征和临床特征,构建了多模态模型。使用哈雷尔一致性指数(C指数)评估多模态模型对BCR的预测性能,并与所有单模态模型(包括放射组学特征、病理组学特征和临床特征)进行比较。结果 放射性组学特征和病理组学特征对测试队列的 BCR 预测均有良好的表现(C 指数分别为 0.742 和 0.730)。多模态模型的预测性能最好,在测试集上的 C 指数为 0.860,明显高于所有单模态模型(所有 P 均小于 0.01)。结论 多模态模型可有效预测PCa患者RP术后的BCR,因此可为术后个体化治疗提供一个新兴的准确工具。关键词磁共振成像、泌尿系统、骨盆、比较研究 本文有补充材料。© RSNA, 2024.

Purpose To investigate the association of tumor arterial burden (TAB) on preoperative MRI with transarterial chemoembolization refractoriness (TACER) and progression-free survival (PFS) in patients with hepatocellular carcinoma (HCC). Materials and Methods This retrospective study included patients with HCC who underwent repeated transarterial chemoembolization (TACE) treatments between January 2013 and December 2020. HCC was confirmed with pathology or imaging, and patients with other tumors, lost follow-up, or with a combination of other treatments were excluded. TACER was defined as viable lesions of more than 50% or increase in tumor number after two or more consecutive TACE treatments, continuous elevation of tumor markers, extrahepatic spread, or vascular invasion. TAB assessed with preoperative MRI was divided into high and low groups according to the median. A Cox proportional hazards model was used to determine the predictors of TACER and PFS. Results A total of 355 patients (median age, 61 years [IQR, 54-67]; 306 [86.2%] men, 49 [13.8%] women) were included. During a median follow-up of 32.7 months, the high TAB group had significantly faster TACER and decreased PFS than the low TAB group (all log-rank P < .001). High TAB was the strongest independent predictor of TACER and PFS in multivariable Cox regression analyses (hazard ratio [HR], 2.23 [95% CI: 1.51, 3.29]; HR, 2.30 [95% CI: 1.61, 3.27], respectively), especially in patients with Barcelona Clinic Liver Cancer stage A or a single tumor. The restricted cubic spline plot demonstrated that the HR of TACER and PFS continuously increased with increasing TAB. Conclusion High preoperative TAB at MRI was a risk factor for faster refractoriness and progression in patients with HCC treated with TACE.

目的 探讨肝细胞癌(HCC)患者术前磁共振成像显示的肿瘤动脉负担(TAB)与经动脉化疗栓塞难治性(TACER)和无进展生存期(PFS)的关系。材料与方法 这项回顾性研究纳入了在 2013 年 1 月至 2020 年 12 月期间接受过多次经动脉化疗栓塞(TACE)治疗的 HCC 患者。HCC经病理学或影像学证实,排除了患有其他肿瘤、失去随访或合并其他治疗的患者。TACER定义为连续两次或两次以上TACE治疗后,存活病灶超过50%或肿瘤数量增加、肿瘤标志物持续升高、肝外扩散或血管侵犯。术前 MRI 评估的 TAB 根据中位数分为高低两组。采用 Cox 比例危险模型确定 TACER 和 PFS 的预测因素。结果 共纳入 355 名患者(中位年龄 61 岁 [IQR,54-67];男性 306 [86.2%],女性 49 [13.8%])。在中位 32.7 个月的随访期间,高 TAB 组的 TACER 明显快于低 TAB 组,PFS 明显低于低 TAB 组(所有对数秩 P < .001)。在多变量考克斯回归分析中,高TAB是TACER和PFS的最强独立预测因子(危险比[HR]分别为2.23[95% CI:1.51, 3.29];HR分别为2.30[95% CI:1.61, 3.27]),尤其是在巴塞罗那临床肝癌A期或单发肿瘤患者中。限制性立方样条曲线图显示,随着 TAB 的增加,TACER 和 PFS 的 HR 不断增加。结论 MRI术前TAB高是导致接受TACE治疗的HCC患者耐药和病情进展更快的危险因素。关键词血管介入 MR 血管造影 肝细胞癌 经动脉化疗栓塞 无进展生存期 MRI 本文有补充材料。© RSNA, 2024.

Tissue ablation techniques have long been used in clinical settings to treat various oncologic diseases. However, many of these techniques are invasive and can cause substantial adverse effects. Histotripsy is a noninvasive, nonionizing, nonthermal tissue ablation technique that has the potential to replace surgical interventions in various clinical settings. Histotripsy works by delivering high-intensity focused ultrasound waves to target tissue. These waves create cavitation bubbles within tissues that rapidly expand and collapse, thereby mechanically fractionating the tissue into acellular debris that is subsequently absorbed by the body's immune system. Preclinical and clinical studies have demonstrated the efficacy of histotripsy in treating a range of diseases, including liver, pancreatic, renal, and prostate tumors. Safety outcomes of histotripsy have been generally favorable, with minimal adverse effects reported. However, further studies are needed to optimize the technique and understand its long-term effects. This review aims to discuss the importance of histotripsy as a noninvasive tissue ablation technique, the preclinical and clinical literature on histotripsy and its safety, and the potential applications of histotripsy in clinical practice.

组织消融技术长期以来一直被用于临床治疗各种肿瘤疾病。然而,其中许多技术都是侵入性的,并可能造成严重的不良影响。组织切削术是一种非侵入性、非电离、非热组织消融技术,有可能在各种临床环境中取代外科手术。组织切削术的工作原理是向目标组织输送高强度聚焦超声波。这些超声波会在组织内产生空化泡,空化泡会迅速膨胀和塌陷,从而将组织机械地分化成无细胞碎片,这些碎片随后会被人体免疫系统吸收。临床前和临床研究已经证明了组织切碎术在治疗肝脏、胰腺、肾脏和前列腺肿瘤等一系列疾病方面的疗效。组织切碎术的安全性总体良好,不良反应极少。然而,还需要进一步的研究来优化该技术并了解其长期效果。本综述旨在讨论组织切碎术作为一种无创组织消融技术的重要性、有关组织切碎术及其安全性的临床前和临床文献,以及组织切碎术在临床实践中的潜在应用。关键词肿瘤微环境 超声-高强度聚焦 (HIFU)、消融技术、腹部/消化道、生殖/生殖系统、非热组织消融、组织切削术、临床试验、临床前应用、聚焦超声 © RSNA, 2024.

Purpose To evaluate long-term trends in mammography screening rates and identify sociodemographic and breast cancer risk characteristics associated with return to screening after the COVID-19 pandemic. Materials and Methods In this retrospective study, statewide screening mammography data of 222 384 female individuals aged 40 years or older (mean age, 58.8 years ± 11.7 [SD]) from the Vermont Breast Cancer Surveillance System were evaluated to generate descriptive statistics and Joinpoint models to characterize screening patterns during 2000-2022. Log-binomial regression models estimated associations of sociodemographic and risk characteristics with post-COVID-19 pandemic return to screening. Results The proportion of female individuals in Vermont aged 50-74 years with a screening mammogram obtained in the previous 2 years declined from a prepandemic level of 61.3% (95% CI: 61.1%, 61.6%) in 2019 to 56.0% (95% CI: 55.7%, 56.3%) in 2021 before rebounding to 60.7% (95% CI: 60.4%, 61.0%) in 2022. Screening adherence in 2022 remained substantially lower than that observed during the 2007-2010 apex of screening adherence (66.1%-67.0%). Joinpoint models estimated an annual percent change of -1.1% (95% CI: -1.5%, -0.8%) during 2010-2022. Among the cohort of 95 644 individuals screened during January 2018-March 2020, the probability of returning to screening during 2020-2022 varied by age (eg, risk ratio [RR] = 0.94 [95% CI: 0.93, 0.95] for age 40-44 vs age 60-64 years), race and ethnicity (RR = 0.84 [95% CI: 0.78, 0.90] for Black vs White individuals), education (RR = 0.84 [95% CI: 0.81, 0.86] for less than high school degree vs college degree), and by 5-year breast cancer risk (RR = 1.06 [95% CI: 1.04, 1.08] for very high vs average risk). Conclusion Despite a rebound to near prepandemic levels, Vermont mammography screening rates have steadily declined since 2010, with certain sociodemographic groups less likely to return to screening after the pandemic.

目的 评估乳腺放射摄影筛查率的长期趋势,并确定与 COVID-19 大流行后恢复筛查相关的社会人口学和乳腺癌风险特征。材料与方法 在这项回顾性研究中,我们评估了佛蒙特州乳腺癌监测系统(Vermont Breast Cancer Surveillance System)提供的 222 384 名 40 岁及以上女性(平均年龄为 58.8 岁 ± 11.7 [SD])的全州乳腺 X 线照相筛查数据,生成了描述性统计数据和 Joinpoint 模型,以描述 2000-2022 年期间的筛查模式。对数二项式回归模型估计了社会人口学特征和风险特征与COVID-19大流行后恢复筛查的相关性。结果 佛蒙特州 50-74 岁女性在过去 2 年中接受过乳房 X 线照相筛查的比例从 2019 年大流行前的 61.3% (95% CI: 61.1%, 61.6%) 下降到 2021 年的 56.0% (95% CI: 55.7%, 56.3%),然后在 2022 年回升到 60.7% (95% CI: 60.4%, 61.0%)。2022 年的筛查依从性仍大大低于 2007-2010 年筛查依从性最高峰时期的水平(66.1%-67.0%)。据连接点模型估计,2010-2022 年期间的年百分比变化为-1.1%(95% CI:-1.5%, -0.8%)。在 2018 年 1 月至 2020 年 3 月期间接受筛查的 95 644 人队列中,2020-2022 年期间重返筛查的概率因年龄(例如,40-44 岁 vs 60-64 岁的风险比 [RR] = 0.94 [95% CI: 0.93, 0.95])、种族和民族(RR = 0.84[95%CI:0.78, 0.90])、教育程度(RR=0.84[95%CI:0.81, 0.86],高中以下学历 vs 大学学历)以及 5 年乳腺癌风险(RR=1.06[95%CI:1.04, 1.08],非常高风险 vs 一般风险)。结论 尽管佛蒙特州的乳腺放射摄影筛查率已回升至接近大流行前的水平,但自2010年以来一直在稳步下降,某些社会人口群体在大流行后恢复筛查的可能性较小。关键词乳腺 X 线照相术 乳腺 健康政策与实践 肿瘤-原发性 流行病学 筛查 本文有补充材料。© RSNA, 2024.

Materials and Methods In this retrospective study, statewide screening mammography data of 222 384 female individuals aged 40 years or older (mean age, 58.8 years ± 11.7 [SD]) from the Vermont Breast Cancer Surveillance System were evaluated to generate descriptive statistics and Joinpoint models to characterize screening patterns during 2000-2022. Log-binomial regression models estimated associations of sociodemographic and risk characteristics with post-COVID-19 pandemic return to screening. Results The proportion of female individuals in Vermont aged 50-74 years with a screening mammogram obtained in the previous 2 years declined from a prepandemic level of 61.3% (95% CI: 61.1%, 61.6%) in 2019 to 56.0% (95% CI: 55.7%, 56.3%) in 2021 before rebounding to 60.7% (95% CI: 60.4%, 61.0%) in 2022. Screening adherence in 2022 remained substantially lower than that observed during the 2007-2010 apex of screening adherence (66.1%-67.0%). Joinpoint models estimated an annual percent change of -1.1% (95% CI: -1.5%, -0.8%) during 2010-2022. Among the cohort of 95 644 individuals screened during January 2018-March 2020, the probability of returning to screening during 2020-2022 varied by age (eg, risk ratio [RR] = 0.94 [95% CI: 0.93, 0.95] for age 40-44 vs age 60-64 years), race and ethnicity (RR = 0.84 [95% CI: 0.78, 0.90] for Black vs White individuals), education (RR = 0.84 [95% CI: 0.81, 0.86] for less than high school degree vs college degree), and by 5-year breast cancer risk (RR = 1.06 [95% CI: 1.04, 1.08] for very high vs average risk). Conclusion Despite a rebound to near prepandemic levels, Vermont mammography screening rates have steadily declined since 2010, with certain sociodemographic groups less likely to return to screening after the pandemic. <b>Keywords:</b> Mammography, Breast, Health Policy and Practice, Neoplasms-Primary, Epidemiology, Screening <i>Supplemental material is available for this article.</i> © RSNA, 2024.</p>","PeriodicalId":20786,"journal":{"name":"Radiology.
