The Danish National Prescription Registry in studies of a biological pharmaceutical: palivizumab - validation against two external data sources.

abstract：BACKGROUND:A number of studies have shown poorer survival among cancer patients with comorbidity. Several mechanisms may underlie this finding. In this review we summarize the current literature on the association between patient comorbidity and cancer prognosis. Prognostic factors examined include tumor biology, diagn...
