Inclusion criteria

Inclusion criteria: (1) Collect blood samples before starting the first treatment in all cases clinically diagnosed with advanced ovarian cancer. In addition, tumor frozen specimens prior to initial drug therapy will be collected. (2) Collect cancer-collected blood samples for all cases diagnosed with platinum-sensitive recurrent ovarian cancer. Furthermore, if the tumor tissue at the time of recurrence is collected by surgery or biopsy, the frozen tumor sample is collected. (3) Collect blood samples before the start of olaparib as maintenance therapy for initial treatment or platinum-sensitive recurrence. (4) Collect blood samples when recurrence or exacerbation is observed after olaparib as maintenance therapy at the first treatment or platinum-sensitive recurrence. If the tumor tissue at the time of recurrence or exacerbation after olaparib administration is collected by surgery or biopsy, a frozen tissue sample is also collected.
