OGS:
For non-metastatic OGS, factors found significant on univariate analysis are shown in Table 3. On multivariable analysis, higher baseline SAP, neurovascular bundle involvement, joint involvement, poor histological necrosis, failure to complete treatment, prior treatment independently predicted inferior EFS.
In the metastatic cohort, failure to complete treatment protocol, poor histological necrosis, tumours not amenable to local treatment and >10 metastases were also predictive of superior EFS on multivariable analysis. (Table 4)
