LIPI, mGPS, and EPSILoN were calculated according to previously reported methodology; optimal cut-offs for SII and PIV were determined using maximally selected rank statistics.

Poor-risk categories of LIPI (PFS p&lt;0.0001, OS p&lt;0.0001), EPSILoN (PFS p=0.0012, OS p=0.0301), PIV (PFS p=0.0147, OS p=0.00543), and SII (PFS p=0.00016, OS p&lt;0.0001) were strongly associated with inferior outcomes.
