How many cycles of chemotherapy are required after removal of Ewing sarcoma of the sacrum

The chemotherapy regimen after resection of sacral Ewing’s sarcoma is related to the pathologic morphologic differentiation, and the shortest course of 6-8 courses is needed, and the course of postoperative chemotherapy will be correspondingly increased in those with a high degree of malignancy, a heavy local invasion, or the occurrence of distant metastasis.
Some Ewing’s sarcoma with better cytomorphological differentiation and early stage of local detection may require 6-8 courses of treatment; some with higher malignant degree, larger local invasion or distant metastasis may require longer chemotherapy treatment courses or even 1-2 years.
Some Ewing’s sarcoma is more sensitive to radiotherapy, and the course of chemotherapy should be decided in combination with radiotherapy. The exact course of treatment depends on long-term follow-up, follow-up, and sequential treatment. Ewing’s sarcoma is usually treated with a combination of treatments, including early radiotherapy and surgery, along with post-surgical radiotherapy, in order to achieve curative treatment.
If you are a patient after sacral Ewing’s sarcoma resection, it is recommended that you communicate fully with your treating doctor, follow the doctor’s instructions, and actively cooperate with the treatment and examination.
