Whether chemotherapy is still needed six months after the end of chemotherapy should be decided according to the specific treatment plan and the situation of recurrence and metastasis. Generally, after completing the established chemotherapy cycle after surgery, in the absence of recurrence, metastasis, etc., there is no need for chemotherapy again. For some patients who have not completed a full cycle of chemotherapy before surgery, it is necessary to continue to complete the remaining cycles of chemotherapy after surgery. Moreover, if tumor recurrence or metastasis is detected, chemotherapy should also be considered. If chemotherapy has been completed for half a year, it is recommended to go to a regular hospital for regular follow-up and make follow-up plans under the guidance of a specialist.
