Winner in Physics/Engineering
Daan Löke (Msc). Demonstration of treatment planning software for hyperthermic intraperitoneal chemotherapy in a rat model, https://doi.org/10.1080/02656736.2020.1852324, Department of Radiation Oncology, Amsterdam UMC, University of Amsterdam, The Netherlands
Born and raised in Friesland in the northern part of the Netherlands, Daan Löke moved to Groningen to obtain his Bachelor degree in Physics in 2015 with a thesis titled ‘Correlation of MR image info with CT to improve the determination of proton stopping powers for proton therapy’ at the center of advanced radiation technology (KVI-CART) at the University of Groningen. Two years later he obtained his Master degree in theoretical physics with the focus on particle physics. His master thesis was entitled ‘The scalar spectrum of non-Abelian gauge theories below the conformal window’ on research performed at the van Swinderen Institute (VSI) for Particle Physics and Gravity at the University of Groningen. After his graduation, he returned to medical physics and was appointed a PhD position in the group of Hans Crezee and Petra Kok at the department of radiation oncology of the Amsterdam UMC/university of Amsterdam, working on the project ‘Development of patient specific treatment planning to enhance and optimize clinical effectiveness of hyperthermic intraperitoneal chemotherapy (HIPEC) in colorectal cancer patients’. Together with Roxan Helderman, Daan aims to improve and optimize HIPEC treatments from a biological and from a physics perspective. His work focuses on the development and experimental validation of computational fluid dynamics-based simulations, explicitly mapping flow patterns in the peritoneal cavity of patients suffering from peritoneal metastasis of colorectal origin. Aim of the software is to optimize these flow patterns and improving thermal homogeneity during the treatment, maximizing the potential enhancement of the chemotherapy used. The paper published in the International Journal of Hyperthermia demonstrates the software in an anatomical rat model. Previous publications described the penetration of chemotherapy during HIPEC (Löke et al, Drug Delivery, 2020), the variation in the application of HIPEC (Helderman & Löke et al. Cancers, 2019), thermal validation of the software (Schooneveldt & Löke et al., Int. J. Heat and Mass Transfer, 2020) and the design of an experimental in vivo HIPEC-setup (Löke & Helderman et al., Cancers, 2020). For finalization of his PhD thesis Daan plans to extend the software toward the application in human patients, with the intention to improve treatments setups such that HIPEC treatments become more effective.

Published on 26 April 2021, Views: 126
Abstract
Purpose
Magnetic resonance guided focused ultrasound (MRgFUS) treatment of tumors uses inter-sonication delays to allow heat to dissipate from the skin and other near-field tissues. Despite inter-sonication delays, treatment of tumors close to the skin risks skin burns. This work has designed and evaluated an open-source, conformable, skin-cooling system for body MRgFUS treatments to reduce skin burns and enable ablation closer to the skin.
Methods
A MR-compatible skin cooling system is described that features a conformable skin-cooling pad assembly with feedback control allowing continuous flow and pressure maintenance during the procedure. System performance was evaluated with hydrophone, phantom and in vivo porcine studies. Sonications were performed 10 and 5 mm from the skin surface under both control and forced convective skin-cooling conditions. 3D MR temperature imaging was acquired in real time and the accumulated thermal dose volume was measured. Gross analysis of the skin post-sonication was further performed. Device conformability was demonstrated at several body locations.
Results
Hydrophone studies demonstrated no beam aberration, but a 5–12% reduction of the peak pressure due to the presence of the skin-cooling pad assembly in the acoustic near field. Phantom evaluation demonstrated there is no MR temperature imaging precision reduction or any other artifacts present due to the coolant flow during MRgFUS sonication. The porcine studies demonstrated skin burns were reduced in size or eliminated when compared to the control condition.
Conclusion
An open-source design of an MRgFUS active skin cooling system demonstrates device conformability with a reduction of skin burns while ablating superficial tissues.

Purpose
To demonstrate the feasibility of irreversible electroporation (IRE) for treating biliary metal stent occlusion in an experimental liver model.
Methods and materials
IRE was performed using an expandable tubular IRE-catheter placed in nitinol stents in the porcine liver. A 3-electrode IRE-catheter was connected to an IRE-generator and one hundred 100μs pulses of constant voltage (300, 650, 1000, and 1300 V) were applied. Stent occlusion was simulated by insertion of liver tissue both ex vivo (n = 94) and in vivo in 3 pigs (n = 14). Three scenarios of the relationship between the stent, electrodes, and inserted tissue (double contact, single contact, and stent mesh contact) were studied. Electric current was measured and resistance and power calculated. Pigs were sacrificed 72 h post-procedure. Harvested samples (14 experimental, 13 controls) underwent histopathological analysis.
Results
IRE application was feasible at 300 and 650 V for the single and double contact setup in both ex vivo and in vivo studies. Significant differences in calculated resistance between double contact and single contact settings were observed (ex-vivo p ˂ 0.0001, in-vivo p = 0.02; Mann–Whitney). A mild temperature increase of the surrounding liver parenchyma was noted with increasing voltage (0.9–5.9 °C for 300–1000 V). The extent of necrotic changes in experimental samples in vivo correlated with the measured electric current (r2 = 0.39, p = 0.01). No complications were observed during or after the in-vivo procedure.
Conclusion
Endoluminal IRE using an expandable tubular catheter in simulated metal stent occlusion is feasible. The relationship of active catheter electrodes to stent ingrowth tissue can be estimated based on resistance values.

Abstract
Objectives
To explore the outcomes of CT-guided percutaneous microwave ablation (MWA) in non-small cell lung cancer (NSCLC) patients, and then develop an effective nomogram to predict the survival.
Methods
NSCLC patients treated with MWA were randomly allocated to either the training cohort or the validation cohort (3:1). The primary outcome measurement was overall survival (OS), whose predictors were identified by univariate and multivariate analyses in the training cohort. Then, a predictive nomogram was developed to predict the OS, with the predictive accuracy evaluated by C-statistic and receiver operating characteristic in both the training and validation cohorts.
Results
A total of 234 patients (training cohort: n = 176; validation cohort: n = 58) and 271 tumors with a median OS of 17.0 ± 12.2 months were included. The predictors selected into the nomogram included tumor diameter (hazard ratio [HR], 2.12; 95% confidence interval [CI], 1.37-3.30; p < 0.001), extrapulmonary metastases (HR, 1.77; 95% CI, 1.06–2.95; p = 0.030), tumor stage (HR, 1.38; 95% CI, 1.07–1.79; p = 0.013), tumor type (HR, 2.00; 95% CI, 1.48–2.72; p < 0.001) and post-MWA TKIs (HR, 0.55; 95% CI, 0.34–0.89; p < 0.001), based on the results of univariate and multivariate analyses. The C-statistic showed good predictive performance, with a C-statistic of 0.838 (95% CI, 0.779–0.897) internally and 0.808 (95% CI, 0.695–0.920) externally (training cohort and validation cohort, respectively).
Conclusions
The nomogram was effective in predicting the OS in NSCLC patients treated with MWA, and could be applied to identify patients who may benefit most from MWA and be helpful for clinical decision making.
Special Article Highlight:
International Journal of Hyperthermia highlighted articles are intended to alert readers to new scientific developments with research results in the form of research articles in the clinical, physical, and biological facets of thermal medicine. In addition I would like to highlight the following review article for IJH readers who may be unfamiliar with the technique and to help promote further research in the field.  My choice for highlighting this article is due to the inclusion of one of my canine family members who was recently treated with histotripsy and had a fantastic outcome.  I am grateful for our members working in the area of ultrasound technology for development of new techniques and implementation of impactful clinical trials.
Thank you, Nicole Levi

Abstract
Histotripsy is the first noninvasive, non-ionizing, and non-thermal ablation technology guided by real-time imaging. Using focused ultrasound delivered from outside the body, histotripsy mechanically destroys tissue through cavitation, rendering the target into acellular debris. The material in the histotripsy ablation zone is absorbed by the body within 1–2 months, leaving a minimal remnant scar. Histotripsy has also been shown to stimulate an immune response and induce abscopal effects in animal models, which may have positive implications for future cancer treatment. Histotripsy has been investigated for a wide range of applications in preclinical studies, including the treatment of cancer, neurological diseases, and cardiovascular diseases. Three human clinical trials have been undertaken using histotripsy for the treatment of benign prostatic hyperplasia, liver cancer, and calcified valve stenosis. This review provides a comprehensive overview of histotripsy covering the origin, mechanism, bioeffects, parameters, instruments, and the latest results on preclinical and human studies.
