1. A method for treating a patient suffering from ovarian cancer following removal of a tumor, the method comprising:
determining whether the patient is predicted to benefit from the administration of bevacizumab, wherein such determination comprises:
determining the patient's gene expression level of microfibril associated protein 2 (MFAP2);
determining the patient's gene expression level of vascular endothelial growth factor A (VEGFA);
determining the size of the tumor tissue remaining post-removal of the tumor;
calculating a recurrence score as follows:
recurrence score=−3.5 surg_outcome+0.23xMFAP2+0.19×VEGFA/bevacizumab-0.15×MFAP2/bevacizumab,
wherein surg_outcome is −1 if the surgical outcome was suboptimal; 0 if the surgical outcome was optimal but tumor tissue smaller than 1 cm remained; or +1 if the surgical outcome was optimal and no visible macroscopic tumor tissue remained,
wherein MFAP2=gene expression level of MFAP2,
MFAP2/bevacizumab=interaction effect between MFAP2 and bevacizumab, and
VEGFA/bevacizumab=interaction effect between VEGFA and bevacizumab;
calculating the patient's risk of recurrence at time t (λ(t)) wherein
λ(t)=λ0(t)erecurrence_score
wherein λ0(t) is the baseline hazard function estimated with a non-parametric strategy;
and
administering bevacizumab to a patient having a lower risk of recurrence with administration of bevacizumab than the risk of recurrence score without administration of bevacizumab.
