Resum
[cast] El c ancer es una enfermedad que lleva muchos a~nos siendo una de las principales causas de mortalidad del
mundo. Se han obtenido una gran cantidad de datos del c ancer colorrectal en Estados Unidos para un per odo
temporal que va desde 1975 hasta 2016. El objetivo de este trabajo ha sido estudiar los factores asociados a
la supervivencia del c ancer colorrectal a trav es del Modelo de Cox y Modelo de Vida Acelerada. Al dividirse
la base de datos en dos ejes temporales, una de pacientes diagnosticados entre los a~nos 1975 y 1984 y otra
con los diagnosticados entre 2004 y 2011, se ha comprobado como la supervivencia de este tipo de tumor ha
mejorado para los tiempos m as recientes. Adem as, se ha podido comprobar como las personas afroamericanas
tienen una menor supervivencia. Como cab a esperar el riesgo de muerte en un plazo de cinco a~nos desde el
diagn ostico del tumor es mayor para las personas que carecen de seguro m edico privado, las que tienen m as
edad, las que tienen un tama~no de tumor m as grande y las que tienen un c ancer de grado m as alto.
[eng] Cancer is a disease that has been one of the world's leading causes of mortality for many years. A large amount of colorrectal cancer data has been obtained in the United States from 1975 to 2016. The objective of this work will be to study the factors associated with the survival of colorrectal cancer using the Cox Model and the Accelerated failure time model. Due to dividing the database into two smaller ones, one with patients diagnosed between 1975 and 1984 and the other with those diagnosed between 2004 and 2011, it has been found that the survival of this type of tumour has improved. Furthermore, it has been veri ed that African- American people have lower survival. As expected, the 5-year risk of death is higher for people without private health insurance, those who are older, those with larger tumour size, and those with higher-grade cancer.
