The expression of P-glycoprotein (P-gp) was studied by immunocytohistochemistry, using the C219 monoclonal antibody, in 39 locally advanced breast cancers and 20 ovarian cancers from previously untreated patients. P-gp was expressed in 46 and 35% of breast and ovarian tumours, respectively. A significant association was observed in both tumour types between P-gp expression and in vitro resistance to doxorubicin. We also observed a higher clinical response rate to doxorubicin +/- vincristine in patients with breast cancers not expressing P-gp. Conversely, no correlation was found between P-gp expression and in vitro resistance to cisplatin or in vivo response to cisplatin +/- cyclophosphamide treatment in ovarian cancers. Our results support the relevance of P-gp expression as a specific indicator of resistance to certain drugs, such as doxorubicin and vincristine, involved in the phenomenon of multidrug resistance in breast and ovarian cancer cells.
