Abstract
The present invention relates to the field of biotechnology, and in particular relates to a pharmaceutical composition comprising a protein kinase inhibitor and a chemotherapeutic drug and use thereof. It is found that in the treatment of platinum-refractory/drug-resistant relapsed advanced ovarian cancer, the remission rates of etoposide or paclitaxel in combination with chiauranib is respectively 40% and 50%, while the remission rate of etoposide alone is about 27%, and the remission rate of paclitaxel alone is about 21%, indicating that the combination of chiauranib and etoposide or paclitaxel in the treatment of platinum-refractory/drug-resistant relapsed advanced ovarian cancer has achieved unexpected synergistic effects.
