Secondary response of ovarian tumors to topotecan treatment.
Three patients presented with ovarian cancer that was initially treated with paclitaxel and platinum-based compounds. Although responses to these agents occurred, tumor progression was evident by elevated CA 125 levels after a period of 11 to 35 months. These patients were then treated with topotecan and exhibited a response and stopped therapy. All patients subsequently had progression of disease. The patients were again treated with topotecan and have experienced favorable responses. All three patients are currently receiving treatment with topotecan and have stable disease. The results presented here suggest that re-treatment with anti-tumor agents, such as topotecan, may be able to elicit a response in tumors previously sensitive to these agents.
