Clinical significance of intratumor heterogeneity for gynecological carcinoma
Heterogeneity is very important to ensure the biodiversity and the existence of nature. Human malignancies consist of cellular sub-populations with various pathological features and biological characteristics. Intratumor heterogeneity includes differences in the histology, antigenicity, immunity, hormone receptors, metabolism, gene changes, growth rate, and the reactions to drugs. Presently, th...
متن کاملHuman Cancer Modeling: Recapitulating Tumor Heterogeneity Towards Personalized Medicine
Despite diagnostic, preventive and therapeutic advances, growing incidence of cancer and high rate of mortality among patients affected by specific cancer types indicate current clinical measures are not ideally useful in eradicating cancer. Chemoresistance and subsequent disease relapse are believed to be mainly driven by the cell-molecular heterogeneity of human tumors that necessitates perso...

متن کاملIntratumor heterogeneity in evolutionary models of tumor progression.
With rare exceptions, human tumors arise from single cells that have accumulated the necessary number and types of heritable alterations. Each such cell leads to dysregulated growth and eventually the formation of a tumor. Despite their monoclonal origin, at the time of diagnosis most tumors show a striking amount of intratumor heterogeneity in all measurable phenotypes; such heterogeneity has ...
متن کاملModelling Tumor-induced Angiogenesis: Combination of Stochastic Sprout Spacing and Sprout Progression
Background: Angiogenesis initiated by cancerous cells is the process by which new blood vessels are formed to enhance oxygenation and growth of tumor. Objective: In this paper, we present a new multiscale mathematical model for the formation of a vascular network in tumor angiogenesis process. Methods: Our model couples an improved sprout spacing model as a stochastic mathematical model of spro...
