Ewing's sarcoma of bone. Experience with 140 patients.

The records of 140 patients with histologically verified Ewing's sarcoma of bone treated between 1969 and 1982 were studied retrospectively. Various factors thought to be relevant to prognosis were analyzed. Three statistically significant factors were found: presence of metastatic disease, elevation of the sedimentation rate, and location of the tumor in the pelvis. In addition, patients who underwent complete surgical excision of the primary lesion had a better survival rate (74% at 5 years) than those who did not (34% at 5 years). It is concluded that patients with surgically accessible lesions should undergo treatment consisting of surgery, chemotherapy, and, in selected cases, radiation.
