Study of Tumor Growth under Hyperthermia Condition
The new concept of keeping primary tumor under control in situ to suppress distant foci sheds light on the treatment of metastatic tumor. Hyperthermia is considered as one of the means for controlling tumor growth. To simulate the tumor growth, a continuum mathematical model has been introduced. The newest understanding of the Warburg effect on the cellular metabolism and diffusion of the nutri...
متن کاملGelatin microcapsules for enhanced microwave tumor hyperthermia.
Local and rapid heating by microwave (MW) irradiation is important in the clinical treatment of tumors using hyperthermia. We report here a new thermo-seed technique for the highly efficient MW irradiation ablation of tumors in vivo based on gelatin microcapsules. We achieved 100% tumor elimination in a mouse model at an ultralow power of 1.8 W without any side-effects. The results of MTT assay...
متن کاملEffects of hyperthermia on normal and tumor microenvironment.
The effects of hyperthermia on pH, local blood flow (LBF) and tissue oxygen tension (TpO2) in several normal and tumor tissues were studied. It was found that TpO2, local blood flow and pH are inhomogeneous in tumor tissue. TpO2 is very low in certain areas which also seem deprived of blood flow and are at very low pH. Hyperthermia has a dual effect: at temperatures below 41 degrees C, it incre...
متن کاملDifferential response of normal and tumor microcirculation to hyperthermia.
RBC velocity and vessel lumen diameter were measured in individual microvessels in normal (mature granulation) and neoplastic (VX2 carcinoma) tissues grown in a transparent rabbit ear chamber. Blood flow rates were determined before, during, and after local hyperthermia treatments at 40-52 degrees for 1 hr. Blood flow in normal tissue increased dramatically with temperature, but stasis occurred...
متن کاملLocal hyperthermia for esophageal cancer in a rabbit tumor model: Magnetic stent hyperthermia versus magnetic fluid hyperthermia
Magnetic-mediated hyperthermia (MMH) is a promising local thermotherapy approach for cancer treatment. The present study investigated the feasibility and effectiveness of MMH in esophageal cancer using a rabbit tumor model. The therapeutic effect of two hyperthermia approaches, magnetic stent hyperthermia (MSH), in which heat is induced by the clinical stent that is placed inside the esophagus,...
