<p>Cancer cells are treated by encapsulating a tumour specific material (I) (esp. an antibody or radioisotope) with a material (II) that can be removed on entering a cancer cell after a preselected time, to produce a total particle size 1 mu. the intravenously injecting the encapsulated particles and removing (II) in situ so that (I) is released in the cancer cells. Cancer cells are killed selectively without harmful effects on normal cells, wherever the cancer cells are located in the patient; cells detached from the tumour and a drift in the vascular system or lymphatic system are also killed. In an example Ga citrate (gallium-67) in saline was admin. to a subject at 0.02-0.1 mC./kg. After 12 hrs. the subject was placed in a large induction coil and treated electromagnetically.</p> |
