In order to establish early and precise methods for evaluating the effect of secondary chemotherapy in patients with recurrent ovarian cancer, both the clinical course of 3 women treated with gemcitabine-based secondary chemotherapy and the potential for early and accurate evaluation of the secondary chemotherapeutic effect of 18F-fluorothymidine (FLT) PET are reported. Standard uptake value with FLT PET decreased earlier than with 18F-fluorodeoxyglucose PET and was better correlated with a reduction in size as measured by CT. FLT PET could become a new standard for monitoring response to gemcitabine-based secondary chemotherapy treatment for recurrent ovarian cancer.
