Page Background

was diagnosed based on mpMRI and targeted biopsies and

who had RP. The risk of PMs is higher for TZ- than for PZ-

originated cancers, whereas there are no differences in

biochemical recurrence (BCR)–free or overall survival

[25]

. Our 35% post/lateral rate of PMs (6 of 17 cases) led

to recurrence in 4 of 6 cases. A frozen section margin

assessment on the predominant side of the tumor might

have led to a more extended excision of the PZ horn or to

immediate RP. Fifth, completion RP was performed for four

patients who recurred, was judged feasible with the

possibility of the nerve-sparing technique, and excellent

oncologic and outcomes were observed with a mean follow-

up of 5 yr for three of four cases. Functional outcomes were

similar to what is observed after RP as the primary

treatment.

Limitations of the study include the small sample size

associated with quite wide CIs for reported outcomes. It also

includes the absence of an alternative biopsy scheme or

approach such as template transperineal mapping for case

selection.

Conclusions

Robotic partial prostatectomy for isolated anterior cancer is

feasible, with good functional results and 86% BCR-free

survival at 24 mo of follow-up. Partial prostatectomy is an

option for highly selected men with anterior cancers as an

alternative to other focal ablative therapy. CIs are quite

wide for reported outcomes, suggesting that while promis-

ing, much more research is needed to verify our initial

outcomes, adding QOL questionnaires to assess overall

benefits or harms of this technique before being recom-

mended or not advised as a reasonable alternative to

standard therapies.
