My mother, 59 years is a CA ovary patient and had undergone total hysteroctomy and 6 cycles chemotherapy with paclitaxel and carboplatin. Everyting was going well for last one year or so, but during past 3 months her CA125 was elevating against negetive CT scan report. Last week FDG PET CT was carried out and it revealed metastisis in liver, lymphnodes in lung and throat, all growth are sub centimiter and some of them with intense FDG intake. What would be the second look treatment for her? Please reply.
