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)
