Treatment of Localized Prostate Cancer in Elderly Patients: the Role of Partial Cryoablation - Beyond the Abstract

With the aging of our society, the improvement of the quality of life of older men, and the increase in life expectancy, there is a serious need for alternative treatment of prostate cancer (PCa). As already suggested by the International Society of Geriatric Oncology (ISGO) since 2017, treatment of PCa in physically fit older patients should be the same as in younger patients, while a curative approach must be discussed for any intermediate risk with at least 10 years of life expectancy.1

Nonetheless, a higher risk of genito-urinary and rectal toxicity after prostatectomy or EBRT should be taken into account when treating this population.2-3 In this perspective, focal treatment (FT) could provide a valid active treatment by minimizing side effects.

We retrospectively collected data from 110 patients who underwent focal or hemiablative cryoablation (Partial gland cryoablation – PGC) from February 2013 to January 2021. Our Institutional cryoablation protocol included patients with EAU low-to intermediate risk unilateral PCa who refused or were not eligible for radical treatments, low-risk PCa who refused active surveillance (AS) or other radical treatments.4 Specifically, this cohort included patients with more than 70 years, good performance status, and strongly motivated to undergo active treatment. Our cohort demonstrated that PGC showed 68.5% for 5-year biochemical recurrence survival and 71.5% for clinical recurrence.

According to Clavien-Dindo classification, no >3a complications occurred during post-operative follow-up.5

Two patients required a further transurethral resection of the prostate (Clavien-Dindo 3a complication: 1.8%), while urge incontinence persisted only in two of them after six months from PGC. No follow-up data regarding sexual function were available.

Our clinical experience taught us how more and more fit and well-informed older patients required active treatment since striking regional differences in the uptake of AS must be taken into consideration. On the other side, the number of older patients with advanced prostate cancer will rapidly increase in the next few years. In our opinion, active treatment must be early and mandatory, with particular regard to the evaluation of health status and prevention of side effects, both prior to and during treatment.

With this in mind, we stressed the need for dedicated guidelines for PCa in older patients and more prospective well-designed studies in this setting.
