A course of chemotherapy may be divided into six cycles or eight cycles, with no significant difference. The number of cycles of chemotherapy depends on the benefit of the tumor treatment, for example, if the tumor is still benefiting by the sixth cycle, chemotherapy is usually continued. Eight cycles of chemotherapy are more damaging to the body compared to six cycles because chemotherapy itself has the side effect of myelosuppression and may also cause damage to other aspects of the body, such as damage to heart muscle cells and lung cells, so the longer the cycle of chemotherapy, the greater the damage to the body. The longer the chemotherapy cycle, the greater the damage to the body. The chemotherapy process is evaluated on the basis of the assessment, i.e., after chemotherapy, by means of laboratory tests or radiological means, such as CT, MRI, ultrasound, etc., to repeatedly make comparisons, and if the chemotherapy is effective, the chemotherapy can be continued, and if the chemotherapy stops at a resting stage, the chemotherapy will not be continued, which is the difference between chemotherapy eight times and six times.
