Patient: Description of the condition (time of onset, main symptoms, hospital visited, etc.): Hello doctor, mom underwent surgery for ovarian cancer on March 20 and has undergone chemotherapy normally since then. The CA125 value was 508 after the surgery, and the CA125 values were 106/34.7/24/22/14/12 after six chemotherapy sessions. Thank you very much. Zhao Xiaodong, Department of Obstetrics and Gynecology, Beijing Hospital Zhao Xiaodong: 1) Generally 6-8 times of chemotherapy after surgery, generally 6 times is enough, of course, if physical conditions allow, 8 times of chemotherapy is also possible, but there is no evidence that 8 times is better than 6 times. 2) There is no difference between this CA12514 and the last 12, do not worry. 3) CA125 rises above 70 or 3 times in a row to be meaningful. The current worry is unnecessary. 4) Now you can follow up every 3 months, the probability of ovarian cancer recurrence is generally higher. Patient: Thank you, Dr. Zhao, I didn’t expect you to give me such a serious and detailed answer. Thank you. Zhao Xiaodong, Department of Obstetrics and Gynecology, Beijing Hospital, Ministry of Health: It’s okay
