What was measured

The current protocol OS2008 (NCT00667342) was closed early due to slow accrual. Thus, with the limited number of patients, the comparison of EFS of OS20008 to that of OS99 (NCT00145639) participants was not done. The 2-year EFS of OS2008 participants is reported here.

Analysis population: OS2008 Localized Resectable Disease group had 31 participants: 14 had events, 17 had no events.

Groups in this outcome

A: Localized Resectable Disease

OS2008 Stratum A participants had primary tumors potentially resectable by aggressive surgery, such as limb-salvage surgery or amputation, and no evidence of metastasis.
