Microvessel density was investigated by immunostaining endothelial cells for factor VIII antigen in 84 non-small cell lung carcinomas and compared with the expression of several resistance-related proteins. Glutathione S-transferase-
, thymidylate synthase, metallothionein and, with limitations, P-glycoprotein were overexpressed in tumors with poor vascularization.
