Uso de modelos matemáticos para la descripción del crecimiento de tumores cancerosos

Abstract: ResumenLa producción de tumores cancerosos o tumorgénesis ha sido estudiada desde principios del siglo XX por matemáticos y físicos interesados en aplicaciones biológicas. En este trabajo se plantean diversos modelos que utilizan ecuaciones diferenciales ordinarias, ecuaciones diferenciales parciales, modelos estocásticos discretos, estadísticos y de análisis numérico para describir el crecimiento de tumores cancerosos. Se muestra un análisis comparativo entre estos modelos matemáticos, estableciendo particula… Show more

“…Marion Piñeros and Raúl Hernando Murillo, with his study: "Incidence of cancer in Colombia: Importance of the information sources in the collection of estimative figures", in which they estimated the cancer incidence in Colombia and compared the figures obtained by varying the information sources for the adjustment by sub-registration of mortality and the basic information for the model, where they obtained that the adjustment of mortality data and the cancer registers that are used in the estimation process influenced significantly and highlight the importance of considering regional differences [5]. Jair Zapata Peña and Alba Cristina Ortiz, with their research: "Use of mathematical models for the description of the growth of cancerous tumors", in which they shown several models that use ordinary differential equations, partial differ-ential equations, discrete-stochastic models, statistical and numeric analytical models to describe the growth of cancerous tumors, where are shown graphic results of simulations for cancer and dead cell populations [6]. The writing is divided into three sections: The first of them is an introduction about cancer, its treatment and an antecedent on the modeling of the disease.…”

“…El crecimiento de las colonias celulares causantes de la formación tumoral, se ve limitada por factores químicos, biológicos y espaciales, lo cual no implica que su proliferación sobre el tejido sano y a otros órganos muestre tendencias deterministas y probabilísticas que pueden ser descritos mediante modelos matemáticos y condicionamientos físicos. El estudio del crecimiento tumoral ha llamado la atención desde el siglo XX a matemáticos interesados en aplicaciones biológicas logrando adaptar modelos de crecimientos poblacionales con el fin de predecir en el tiempo el tamaño de una determinada población de células carcinogénicas [1].…”
