Clinical and Histologic Predictive Factors of Response to Induction Chemotherapy in Head and Neck Squamous Cell Carcinoma.

abstract：:Remarkable improvements have been made in blood safety since the onset of the HIV epidemic. However, the current paradigm does not prevent all transfusion-transmitted infections and is reactive to new agents, thus accepting that some patients may be harmed before preventive measures are introduced. Several methods are...
