Course and prognosis
The prognosis in the presence of bone cancer depends largely on the time of diagnosis. In addition, the age of the affected patient and the shape and size of the bone tumor play a decisive role in this context. The fact whether it is a primary tumor or a distant metastasis also influences both the course and the prognosis.
In a patient suffering from this form of bone cancer, the question of whether metastases have already formed is of crucial importance. If the bone cancer has not yet metastasized, it can be assumed that 62 out of every 100 patients are still alive approximately five years after diagnosis. With very early diagnosis and small tissue changes, the majority of affected patients can even recover completely.
However, if the bone cancer has already spread in the form of metastases, life expectancy will drop rapidly. In the case of this form of bone cancer, the malignant tumor cells are mainly found in the area of the bone marrow. Due to this fact, the prognosis of affected patients can be significantly improved by early initiation of chemotherapy. In general, it can be assumed that approximately six to seven out of ten patients with Ewing’s sarcoma survive for more than five years. The same applies to this form of bone cancer: the earlier the tumor is diagnosed, the better the prognosis.
