Hence, the ratios of alive tumor cells to total tumor tissue in 64Cu-DOTHA2-PSMA and 177Lu-PSMA-617 groups were lower than with natCu-DOTHA2-PSMA group (p < 0.001 and p = 0.04, respectively) and with non-treated control group (p = 0.002 and p = 0.04, respectively) (Figure 4O). Here, FOLH1 is linked to neoplasm.
