The treatment cycle for Ewing sarcoma ranges from six months to two years, and even longer in some patients. There are many treatment options for Ewing sarcoma, which are mainly determined according to the staging and pathological morphology, and the treatment cycle is mostly kept between 0.5-2 years, and even longer for some patients, which is different for each person and the treatment time, and there is no way to be completely sure. If the patient’s staging is earlier and the degree of malignancy is lower, it can be recovered in about half a year after timely radical surgical resection; some patients need to be treated with radiotherapy and chemotherapy after surgery, and the cycle needs to be prolonged to 6-8 months; however, if it is a Ewing’s sarcoma patient with higher degree of malignancy, it will need radiotherapy and chemotherapy for 1-2 years, and some of them will even be longer. Patients are advised to actively cooperate with doctors for treatment and keep a good mindset in order to prolong the survival period.
