Perioperative and Functional Outcomes of Robot-Assisted Radical Prostatectomy in Octogenarian Men

Complications of single-port robot-assisted radical prostatectomy: multi-institutional analysis from the Single-Port Advanced Research Consortium (SPARC)

OBJECTIVE

To evaluate the perioperative complications of single-port robot-assisted radical prostatectomy (SP-RARP).

PATIENTS AND METHODS

A retrospective review was performed on the prospectively maintained, Institutional Review Board-approved, multi-institutional Single-Port Advanced Research Consortium (SPARC) database. A total of 1103 patients were identified who underwent three different approaches of SP-RARP between 2019 and 2022 using the purpose-built SP robotic platform. In addition to baseline clinical, perioperative outcomes, this study comprehensively analysed for any evidence of intraoperative complication, as well as postoperative complication and readmission within 90 days of the respective surgery.

RESULTS

Of the 244, 712, and 147 patients who underwent transperitoneal, extraperitoneal, and transvesical SP-RARP, respectively, intraoperative complications were noted in five patients (0.4%), all of which occurred during the transperitoneal approach. Two patients had bowel serosal tears, two had posterior button-holing of the bladder necessitating repair, and one patient had an obturator nerve injury. Postoperative complications were noted in 143 patients (13%) with major complications (Clavien-Dindo Grade ≥III) only identified in 3.7% of the total cohort. The most common complications were lymphocele (3.9%), acute urinary retention (2%), and urinary tract infection (1.9%). The 90-day re-admission rate was 3.9%.

CONCLUSION

The SP-RARP is a safe and effective procedure with low complication and readmission rates regardless of the approach. These results are comparable to current multi-port RARP literature.

Outcomes of dose-escalated IMRT and ADT in Octogenarians with prostate cancer

INTRODUCTION

We evaluated long-term outcomes for octogenarians with localised prostate cancer treated using dose-escalated image-guided intensity-modulated radiation therapy (IMRT) at our institution.

METHODS

The charts of octogenarians treated for localised prostate cancer were retrospectively reviewed. Overall survival (OS), prostate cancer-specific survival (PCaSS), toxicity rates and changes from baseline were collected.

RESULTS

The median follow-up was 97 months. Of 107 eligible patients, 27.1% had intermediate-risk and 72.9% had high-risk localised prostate cancer. Median dose was 78Gy, and 97.2% received ADT. OS was 91.4% and 67.2% at 5 and 10 years. PCaSS was 98.0% and 88.7% at 5 and 10 years. In all, 39 (36.4%) of patients died, with the cause of death known in 30: in 26.7% of these patients, prostate cancer was the cause of death. Grade ≥ 2 late GI and GU toxicity was 0.9% and 24.3% respectively. In all, 11.2% and 22.4% of patients reported worsening of GI or GU function from baseline, and 13.1% and 21.5% reported improvement in GI and GU function compared to baseline.

CONCLUSION

Selected octogenarian patients with localised prostate cancer appear to benefit from radiation therapy and ADT. Despite excellent long-term PCaSS, 26.7% of patients died of prostate cancer. Rates of GI and GU toxicity were acceptable, and deterioration of urinary and bowel function compared to baseline was just as common as improvement in function from baseline.

Surgical Tolerability and Frailty in Elderly Patients Undergoing Robot-Assisted Radical Prostatectomy: A Narrative Review

Simple Summary

Life expectancy in Western countries and East Asian countries has incremented over the past decades, resulting in a rapidly aging world, while in general, radical prostatectomy (RP) is not recommended in elderly men aged ≥75 years. Together with the evolving technique of robotic surgeries, surgical indications for RP should be reconsidered in ‘elderly’ and ‘frail’ men, since this procedure has now become one of the safest and most effective cancer treatments for prostate cancer. One important element to determine surgical indications is surgical tolerability. However, evidence is scarce regarding the surgical tolerability in elderly men undergoing robot-assisted radical prostatectomy (RARP). In this review, we focused on the surgical tolerability in ‘elderly’ and/or ‘frail’ men undergoing RARP, with the intent to provide up-to-date information on this matter and to support the decision making of therapeutic options in this spectrum of patients.

Abstract

Robot-assisted radical prostatectomy (RARP) has now become the gold standard treatment for localized prostate cancer. There are multiple elements in decision making for the treatment of prostate cancer. One of the important elements is life expectancy, which the current guidelines recommend as an indicator for choosing treatment options. However, determination of life expectancy can be complicated and difficult in some cases. In addition, surgical tolerability is also an important issue. Since frailty may be a major concern, it may be logical to use geriatric assessment tools to discriminate ‘surgically fit’ patients from unfit patients. Landmark studies show two valid models such as the phenotype model and the cumulative deficit model that allow for the diagnosis of frailty. Many studies have also developed geriatric screening tools such as VES-13 and G8. These tools may have the potential to directly sort out unfit patients for surgery preoperatively.
