Drug sensitivities of 76 human tumor lines/nude mice to 9 anti-cancer drugs were tested. Human tumor lines include pancreas cancers, brain tumors, neuroblastomas and etc. Tested anti-cancer drugs include MMC, 5-FU, and etc. When clinically equivalent dose of anti-cancer drugs were administered, drug sensitivities of these carcinomas were well correlated with clinical one, although blood brain barrier must be considered when brain tumors were tested. Our drug sensitivity panel revealed that cancers originated from the same organ showed the same tendency of drug sensitivity. Therefore, our drug sensitivity panel is thought to be useful to know the anti-cancer spectrum of newly developed anti-cancer drugs. Our panel is also useful to study the chemotherapy of rare cancers, because clinical studies of rare cancers are difficult. Expression of P-glycoprotein is correlated with drug resistance when treated with CED, but is not correlated with those when treated with MTD (maximum tolerate dose). That is human tumor lines with P-glycoprotein detected by C219 monoclonal antibody showed resistance to ADR, VCR and VLB when treated by CED, but the relationship was not observed when treated with MTD.
