Microwave Ablation of Localized Liver Cancer Using Personalized Patient Treatment Planning: A Comprehensive Investigation Available to Purchase

Microwave ablation (MWA), a therapy for localized cancer therapy, uses microwave-generated electromagnetic waves to destroy cancerous tumor cells without affecting much surrounding healthy tissues. This process involves exposing the cancerous tissue to a coaxial antenna emitting microwaves, raising the tumor temperature. Precise temperature control is essential to prevent damage to nearby healthy cells, requiring close monitoring. Treatment planning in India faces challenges due to the lack of oncological experts. To provide accessible and affordable care, we propose establishing a specialized patient treatment planning that combines the expertise of oncological surgeons and engineers. Proposed patient treatment planning will be using numerical analysis to solve Maxwell's equations and the bioheat equation using comsolmultiphysics software with finite element method to analyze temperature distribution, tissue damage, and electrothermal effects, which may be distributed as an executable standalone application for the clinician. Results indicate that microwave power significantly affects temperature and thermal damage, with 10 W power effectively destroying tumor cells with minimal harm to surrounding tissue, also shows the maximum temperature rises by 2.2–11% with each addition in power input of 2 W for the probes. The importance of blood perfusion has been brought to light in methods such as MWA because of the large difference in simulation outcomes between situations with and without blood perfusion. The maximum temperature drops to 3.6–8.61% for different power inputs. Last but not least, MWA is preferred where the tissue contains excess water due to a high rate of thermal damage.
