ABSTRACT:
A novel vaccine for use in the immunotherapy of neoplastic disease is prepared by a procedure wherein cancerous tissue is surgically removed from a patient to be treated and the tissue is disaggregated into its component cells which are then suspended in water and subjected to hydrodynamic turbulence sufficient to disrupt the cells. The "cell disruption material", possessing cancer-specific antigen, and which comprises cell surface membranes and in some cases also intracellular particles, is mixed with a source of maganous ion (e.g., manganese hydrogen phosphate) and, optionally, a tri-phosphate gel (e.g., manganese tri-phosphate) to produce the vaccine. When inoculated into the patient, the vaccine promotes regression of the cancer through stimulation of the patient's immune response.
