Abstract:
A method for treating a cancer includes administration of an endotoxin to a patient at least a portion of whose neoplastic cells express the CD14 surface receptor. The endotoxin can be administered concurrently or sequentially with a binding protein capable of binding the endotoxin and, for example, where the endotoxin is a lipopolysaccharide or a nontoxic portion of a lipopolysaccharide, it may for example be administered concurrently with a lipopolysaccharide binding protein. Also, the method including a step of first determining whether a portion of the patient's neoplastic cells express the CD14 surface receptor and, if not, administering to the patient prior to or concurrently with the endotoxin a cytokine. Also, a composition for treating a cancer, that includes an endotoxin in combination with at least one cytokine. Administration of the composition can provide more effective treatment of cancers than administration of a composition containing one or more cytokines alone.
