Factors associated with survival a one year of operated patients with cancer ampullary or pancreas

OBJECTIVE: Determine the factors associated with survival a one year of patients operated with ampullary and pancreatic tumors. MATERIALS AND METHODS: A retrospective descriptive study of a cohort of patients with application of survival analysis based on secondary data. Absolute and relative frequencies for qualitative variables were estimated; and measures of central tendency and dispersion for quantitative variables. Overall survival was estimate by the Kaplan-Meier method, in the bivariate analysis was used the Log-Rank test and to establish the factors associated with survival was made a model Proportional Hazards of Cox. RESULTADOS: La supervivencia a un ano de los 70 pacientes operados fue del 62,5 %. Los factores asociados a la supervivencia ajustada fueron la sepsis, sangrado posoperatorio, antigeno carcinoembrionario, trasfusion de globulos rojos, sangrado intraoperatorio, cirugias previas de abdomen y edad. CONCLUSIONES: El conocimiento que se obtuvo de la supervivencia a un ano de los pacientes operados con cancer de pancreas y ampular, permitira crear estrategias encaminadas a la intervencion de los factores asociados, y generar informacion que pueda conllevar a mejorar el pronostico de los pacientes.
