FOLH1 and neoplasm: Whole-body SUVmean and tumor load were associated with rPFS (HR, 0.86[95% CI: 0.82, 0.90; P < .001] and 1.02 [95% CI: 1.01,1.04; P < .001], respectively) in the177Lu-PSMA-617 plus SOC arm, with SUVmean as the strongestpredictor in the final treatment-adjusted multivariable model (Fig 3, Table 3).
