Key result
A short-term intensive chemotherapy regimen for Ewing's sarcoma yielded a 5-year event-free survival rate of 45% overall and 48% for patients with localized disease at diagnosis.

Does a short-term intensive regimen improve event-free survival in patients with Ewing's sarcoma?
A short-term intensive regimen for Ewing's sarcoma yielded a 45% 5-year event-free survival rate, but distant metastases remained the most common form of failure, highlighting the need for better systemic treatments.
Modest EFS with short intensive VAC in Ewing sarcoma warrants caution against routine adoption; leaves open need for superior systemic therapies.
Twenty-two patients received a short-term intensive regimen for Ewing's sarcoma between November 1977 and December 1981. The regimen consisted of vincristine (1.5 mg/m2) on day 1, and doxorubicin HCl (75 mg/m2) plus cyclophosphamide (1,000 mg/m2) on day 2. Six cycles were given at 28-day intervals. Local irradiation was started shortly after cycle 2. Eight patients with lesions of expendable bones also underwent surgery as part of the treatment to the primary site, 4 at the end of chemotherapy and 4 at diagnosis. The 5-year event-free survival rate was 45% for all patients and 48% for those with localized disease at diagnosis. Two patients died of treatment-related toxicity. The most common form of failure was distant metastases, indicating that finding a better systemic treatment remains the problem in eradicating Ewing's sarcoma.

Marcus et al. (1991) conducted an observational in Ewing's sarcoma (n=22). Short-term intensive regimen (vincristine, doxorubicin, cyclophosphamide) was evaluated on 5-year event-free survival rate. A short-term intensive chemotherapy regimen for Ewing's sarcoma yielded a 5-year event-free survival rate of 45% overall and 48% for patients with localized disease at diagnosis.
