been on maintenance therapy, had the first round, completed last week. During the first cycle my CA125 leves actually had risen, the drug is niraparib. The doctor has said it has now slightly gone up from last count at 36, so bloods every two weeks. Macmillian has said that with maintenance drugs that work in a similar way, turmour flair ups occur and usually level out and eventually go down. I do hope this is the case........anyone else had this happen to them.
