E.2.2 | Secondary objectives of the trial |
Evaluate the Safety of experimental treatment Compare final degree of hypertrophy after surgery and how the biochemical parameters of liver function are modified in both groups. Assessment of different morphological changes that occur in the same following administration of G-CSF Compare the postoperative morbidity between groups. Analyze the event-free survival (death from any cause) in groups. |
Evaluar la Seguridad del tratamiento experimental. Comparar cual es el grado de hipertrofia final tras la cirugía y cómo se modifican los parámetros bioquímicos de funcionalidad hepática, en ambos grupos.
