Prognosis

Whether or not recurrences occur is strongly dependent on the extent of metastasis formation, the response to preoperative chemotherapy and the “radicality” of tumor removal. It is currently assumed that the five-year survival probability is about 50%. In particular, surgical improvements over the last 25 years have made it possible to improve the probability of survival The survival rate decreases for primary metastases.

Here the survival rate is about 35% . The chances of recovery from Ewing’s sarcoma, as with other cancers, are initially considered to vary from person to person, as statistics only show average recovery and survival rates. The chances of recovery are increased if the tumor can be completely removed by surgery.

Before this, chemotherapy should be administered to reduce the size of the tumor. After the surgical removal of the tumor, a further chemotherapy should be performed to kill any remaining tumor cells. If the tumor cannot be removed completely by surgery, the chances of recovery are much lower.

Here, too, a follow-up treatment with chemotherapy should be carried out. A tumor that cannot be operated on should be irradiated in any case. In general, it can be said that the chances of healing Ewing’s sarcoma are worse if metastases are already present at the time of diagnosis. This means that the tumor has spread and continues to grow elsewhere in the body.

Survival rate

Survival rates in general are given in medicine as a statistical value of the “5-year survival rate”.This states in percent how large the number of survivors is after 5 years in a defined patient group. For Ewing’s sarcoma, the stated survival rate lies in a range between 40% and 60-70%. These broad ranges result from the fact that the survival rate depends on the degree of infestation of the respective bone region. For example, if bones of the arms and/or legs are affected, the 5-year survival rate is 60-70%. If the pelvic bones are affected, the survival rate is 40%.
