The tumor-to-kidney (T/K) ratios (Figure 5) remained constant for [111In]In-PSMA-617 (0.2 to 0.3) and [111In]In-22 (0.08 to 0.09) but increased over time for [111In]In-30 (0.02 to 0.2) due to prolonged tumor retention and clearance from the kidneys at 24 h. The gene discussed is FOLH1; the disease is neoplasm.
