In subgroup analysis comparing the allogeneic and autologous PBT group, patients in allogeneic PBT group showed younger age (p = 0.001), a higher rate of LRP/RARP compared to ORP (p = 0.007), a high frequency of PLND (p < 0.001), a longer operative time (p < 0.001), a higher EBL (p < 0.001), a higher frequency of salvage RT (p < 0.001), higher rates of BCR (p < 0.001), cancer-specific death (p = 0.014), and all-cause death (p = 0.001). Here, BCR is linked to cancer.
