Ewing's sarcoma Prognosis

Prognosis for Ewing's sarcoma without the transfer of Women is better than men. The prognosis of Ewing's sarcoma is not close relationship for patients with age, sex, the impact of tumor location is an important factor in prognosis. Physically located in the primary than those located in the pelvis, sacrum good prognosis, such as digital trunk. Tumor on the limb, the distal limb than those located proximal limbs good. According to statistics, the primary tumor in patients with trunk 3-year disease-free survival rate was 53%, primary physical 3-year survival rate was 75%. Pelvic tumor is located in the worst prognosis, 5-year survival rate was 21%, while those located in other parts of the body was 46%. The impact of tumor size is another major factor in prognosis, where the tumor volume less than 100ml, 3-year disease-free survival rate was 80% larger than 100ml are only 32%; where tumor chemotherapy can reduce or disappear, in the histological showed a good response, and prognosis better than the poor response, 3-year disease-free survival rates were 79% and 31%. According to statistics, the multi-drug combination chemotherapy over single-drug chemotherapy program good prognosis; in the treatment of patients with Ewing's sarcoma, a fever, weight loss, anemia, serum lactate dehydrogenase higher than the 170U, erythrocyte sedimentation rate of more than 33mm / h, significantly higher white blood cell count, and prompted a poor prognosis.
