Due to the high uptake in the tumor and the fast clearance rate, the tumor-to-blood (T/B), tumor-to-muscle (T/M) and tumor-to-kidney ratios were 17.59, 48.38 and 1.75, which were higher than those of [177Lu]Lu-PSMA-617(15.58 for T/B, 46.75 for T/M and 1.40 for T/K), [177Lu]Lu-PSMA-BP (9.61 for T/B, 29.80 for T/M and 1.34 for T/K), and [177Lu]Lu-PSMA-4PY (6.07 for T/B, 29.00 for T/M and 1.59 for T/K). The gene discussed is FOLH1; the disease is neoplasm.
