Intermediate-Term Oncological Outcome Assessment for Robotic Assisted Radical Prostatectomy Comparing Retzius Sparing to Standard Approach in a Randomized Control Cohort

INTRODUCTION

Retzius sparing prostatectomy was promoted with the early continence result. The long-term oncological outcome is still unknown. In this study, we aimed to compare the Intermediate-term oncologic outcomes of these two approaches in patient's cohort who was treated as part of a randomized controlled trial.

METHODS

A total of 120 patients were previously randomized equally to receive retzius sparing (RS-RARP) versus standard robotic assisted laparoscopic radical prostatectomy (S-RARP) between January 2015 to April 2016. Baseline, surgical, and pathological characteristics as well as oncologic outcomes were assessed. The analysis was done based on the treatment received.

RESULT

Sixty-three patients underwent S-RARP while 57 patients underwent RS-RARP. There was no statistically significant difference in the baseline nor surgical characteristics. The median follow up was 71.24 (IQR 59.75 - 75.75). There were more pathological T3 diseases in RS-RARP. There was no significant difference in the positive margin status nor the biochemical recurrence rate among both groups. After S-RARP and RS-RARP, 6 and 10 patients had biochemical recurrence and the 5-years biochemical recurrence free survival were 91% and 85%, respectively. (p= 0.21) Conclusion: In this cohort, there was no difference in biochemical recurrence in the patients who received either technique. Further mutli-institutional studies with a larger sample size and longer follow up are required.

Temporal and Racial Trends in Prostate-specific Antigen Screening for U.S. Men With a Family History of Prostate Cancer

INTRODUCTION

Limited data exist on trends in PSA screening in men with a family history of prostate cancer. The aims of our study were to (1) study age-stratified temporal trends in PSA screening from 2000-2018 for men with a family history of prostate cancer and Black men with a family history of prostate cancer, and (2) identify determinants associated with receipt of PSA screening in the aforementioned groups.

METHODS

We identified men aged ≥40 years without a prior history of prostate cancer using data from National Health Interview Survey 2000-2018 who self-reported PSA testing in the last 12 months. Age-stratified temporal trends and weighted multivariable logistic regression analyses were assessed.

RESULTS

PSA screening increased for men with a family history of prostate cancer between National Health Interview Survey 2000 (28.9%) and 2005 (41.9%), with stable rates for the following years. Black men with a family history of prostate cancer showed no significant change in PSA screening rates regardless of age. Controlling for sociodemographics and access to health care provider, younger age (40-54) and later survey years (2013-2018) were associated with a lower likelihood of PSA screening overall and for Black men, but not for those with a positive family history.

CONCLUSIONS

Data from a nationally representative study of U.S. men indicated that the annual PSA screening rates for men with a family history of prostate cancer was higher than reported for the overall male population. We believe this represents the first study on trends and determinants of PSA screening in U.S. men with a family history of prostate cancer.
