Special Issue Information

Dear Colleagues,

Energy-based tumor ablation has become a critically alternative modality to treat tumors in various organs in clinics, and it has been developed into different modalities, such as radiofrequency ablation, microwave ablation, laser ablation, high-intensity focused ultrasound, cryoablation and irreversible electroporation. Mathematical modeling is an important tool in the field of tumor ablation for exploring the working principle of ablation with different modalities, designing novel protocols for different ablation modalities, predicating ablation outcome, etc. Furthermore, an accurate mathematical model can be used as a testbed, replacing in vivo experiments, which saves many resources (e.g., samples of animals, etc.). A mathematical model is also necessary for optimizing the treatment protocol. This Special Issue will aim to collecting papers, which represent the state of the art of mathematical modeling for energy-based tumor ablation applications and provide further perspectives of this subject. The topics of this Special Issue include, but are not limited to:

  • Principal-based mathematical modeling;
  • Empirical-based mathematical modeling;
  • Data-driven mathematical modeling;
  • Monte Carlo simulation;
  • Molecular dynamics simulation;
  • Novel mathematical modeling concepts and techniques;
  • Mechanisms of tumor ablation with different modalities;
  • Bioheat transfer;
  • Design of novel treatment modalities;
  • Cellular responses to electric fields;
  • Molecular responses to electric fields;
  • Mathematical modeling of tissues and anatomy.

In order to explore the bioelectric effect of 5 ns pulsed electric fields on tumor cells, a spherical single-cell multiphysics model was first established based on the finite element simulation platform. In consideration of the dielectric relaxation of the biological plasma membrane under the high-frequency electric fields, the electroporation and Maxwell stress tensors on the cell membrane and nuclear envelope were analyzed; secondly, taking MDA-MB-231 cells as the research object, combined with fluorescent probe technology, the state change and fluorescence dissipation of its subcellular structure exposed to pulse fields were studied. The results showed that 5 ns pulsed electric fields directly acted inside the cell, causing an electroporation effect and tensile stress on the nuclear envelope, destroying the integrity and order of the cytoskeleton, and damaging the functions of subcellular structures including endoplasmic reticulum, mitochondria, etc. This study provides theoretical and experimental evidence for the research and application of a high-voltage short pulse in the field of biomedical engineering.

The electroporation technique utilizes pulsed electric fields to induce porous defects in the cell membrane, and the technique can be used for delivering drugs into cells and killing cancer cells. To develop an electric pulse protocol in the clinic with this technique, the key issue is to understand the evolution of pores in the cell membrane during the process of electroporation. This paper presents a study to address this issue. Specifically, a mathematical model of single-cell electroporation (SCE) was developed, which includes pore area ratio (PAR) as an indicator of the electroporation dynamics and area weight for considering the 3D nature of cells. The model was employed to simulate the electroporation of a single cell with different high-frequency irreversible electroporation (H-FIRE) protocols. The simulation result has found that the change of PAR with respect to the time duration of electroporation follows a sigmoid pattern to increase under specific protocols, which is called the cumulative effect of PAR. Subsequently, the relationship between the protocol of H-FIRE, described by a set of pulse parameters such as pulse width, pulse delay, electric field strength, and pulse burst duration, and the cumulative effect of PAR was established, which thereby allows designing the protocol to kill cells effectively. The study concluded that the proposed SCE model, along with the cumulative effect of PAR, is useful in designing H-FIRE protocols for the ablation of cancer tumors in the clinic. Full article

Single-antenna microwave ablation (MWA) is mainly used to treat small tumors less than 3 cm in diameter. To obtain a larger coagulation zone in a single ablation, a dual-antenna ablation approach was proposed. A three-dimensional finite element method (FEM) simulation model of parallel dual-antennas was developed. Ex vivo experiments at 50 W for 8 min were performed to verify the model. Both the temperature changes in tissue and the size of the coagulation zone were recorded. The effects of dual-antenna spacing, heating power, and blood perfusion on the coagulation zone were analyzed. Fifteen experiments were carried out. The errors between the mean measurements and simulated results at the set temperature points were 1.08 °C, 0.95 °C, and 2.1 °C, respectively. For the same conditions, the blood perfusion of 1.0, 1.5, and 3.0 kg/(m3·s) can result in a reduction in the coagulation volume by 18.4%, 25.4%, and 42.5%. As the spacing increased, the coagulation zone of each antenna started to fuse together later and the resulting integral coagulation zone became larger. Dual-antenna MWA is expected to be used for the treatment of tumors larger than 5 cm in diameter. Full article
