Generally speaking, a course of chemotherapy is 21 days, and chemotherapy regimens include both first-line and second-line regimens. The first-line regimen, which is paclitaxel combined with platinum drugs, requires 6-8 courses of treatment. Generally speaking, fewer patients are able to adhere to the 8 courses, but if they can adhere to the full 8 courses, they will achieve good treatment results. Chemotherapy has both advantages and disadvantages, it can kill tumor cells, but also affect the normal tissues of patients and have certain side effects. The treatment process should reduce the side effects of chemotherapy and improve the patient’s compliance and tolerance.
