Hello, Dr. Liang, we started chemotherapy one month after operation. So far, I have done six courses of treatment (biweekly therapy, the specific plan has been uploaded, see the diagnosis certificate). The doctor here said that 10- 12 courses were needed, for fear that the patient would not persist. I had a CT scan a month ago and found no metastasis. Do I need to continue chemotherapy? At present, the patient is in good health, thank you very much!
