La presente tesis de investigación universitaria, tiene como objetivo principal determinar el grado de relación existente entre manejo de conceptos y capacidad de análisis en los estudiantes de la Universidad Nacional de Trujillo, sede Provincia de Santiago de Chuco, Departamento de La Libertad. El presente trabajo investigativo tuvo que recurrir a los métodos inductivo, deductivo, de discusión y sintético. Por consiguiente, para poder contrastar las hipótesis de investigación se aplicó un diseño correlacional a un solo grupo de muestra, en donde se hizo la comparación referente a la prueba de manejo de conceptos y capacidad de análisis; y para medir el valor de la prueba, tuvo que ser sometido a expertos en la materia para corroborar su validez y seguridad de la misma. Para evaluar el resultado de las hipótesis se aplicó una prueba estadística “la prueba correlacionalâ€...

OBJECTIVES: To determine the prognostic significance of the state of estrogen receptor (ER) and identify prognostic factors related to the five-year survival in patients with operable breast cancer with negative axillary nodes (CMOGAN). DESIGN: Retrospective. MATERIALS AND METHODS: 37 patients undergoing CMOGAN classical radical mastectomy (n = 28) or modified (n = 9) is evaluated in the Bethlehem Hospital from 1966 to 1995. estrogen receptor status was determined according to immunohistochemical method standard. RESULTS: The mean age was 48 ± 11.1 years. Four cases it had thirty-three stage I and stage II. Seven cases were ER (+) and thirty RE (-). In patients with ER (-) by univariate analysis using the log-rank test, only the type of mastectomy was significantly related to the five-year survival (p = 0.046). In the multivariate Cox analysis, histological grade (p = 0.0361), nuclear g...
