Abstract
A diagnostic method for detecting cancerous epithelial cells by selectively marking the mitochondria of the cancer cells, by delivering to the epithelium a cationic supravital mitochondrial marking agent. Selective killing of cancerous epithelial cells in the presence of normal cells is effected by delivering a cationic supravital mitochondrial marking agent to epithelial cancer cells. The killing agent can also comprise the reaction product of the marking agent and a cancer chemotherapeutic drug.
Claims1
A diagnostic method for in vivo detection of cancerous epithelial cells by selective marking of the mitochondria thereof, comprising the steps of:
- topically delivering to the epithelium a cationic supravital mitochondrial marking agent, said agent be a member of the group consisting of cationic supravital mitochondrial marking agents other than toluidine blue O;
- and detecting the retention of said agent by the mitochondria of cancerous and precancerous cells on said epithelium.
