Abstract

Background

Scant data exists on the impacts of prostate radiation on ejaculatory function. We performed a systematic review and meta-analysis to assess ejaculatory outcomes in men after prostate radiation.

Methods

We queried PubMed, Embase, and Web of Science to identify 17 articles assessing ejaculatory function post-radiation. The primary outcome was anejaculation rate and secondary outcomes included ejaculatory volume (EV), ejaculatory discomfort, and mean decline in ejaculatory function scores (EFS). We assessed study quality with the Newcastle-Ottawa scale. We calculated pooled proportions using inverse variance and random effects models.

Results

We identified 17 observational studies with 2156 patients reporting ejaculatory profiles post-radiation. Seven studies utilized external beam radiation therapy, 7 brachytherapy, 1 stereotactic RT and 2 utilized either external or brachytherapy. Ten studies reported an anejaculation rate. Pooled proportion of patients having anejaculation, decreased EV and EjD were 18% (95% CI, 11–36%), 85% (95% CI, 81–89%) and 24% (95% CI, 16–35%), respectively. Five studies reported decline in EFS post-radiation.

Conclusions

Patients receiving radiation treatment may experience significant changes in their ejaculation, such as the absence of ejaculation, reduced EV, and EjD. It is important to counsel them about these potential side effects.

前列腺癌放疗后的射精功能:系统回顾和荟萃分析
背景有关前列腺放射治疗对射精功能影响的数据很少。我们进行了一项系统综述和荟萃分析,以评估前列腺放射治疗后男性的射精功能。方法我们查询了PubMed、Embase和Web of Science,确定了17篇评估放射治疗后射精功能的文章。主要结果是无射精率,次要结果包括射精量(EV)、射精不适感和射精功能评分(EFS)的平均下降率。我们采用纽卡斯尔-渥太华量表评估研究质量。我们使用反方差和随机效应模型计算了汇总比例。结果我们确定了17项观察性研究,共有2156名患者报告了放疗后的射精情况。其中 7 项研究使用了体外放射治疗,7 项使用了近距离放射治疗,1 项使用了立体定向 RT,2 项使用了体外放射治疗或近距离放射治疗。10 项研究报告了无射精率。无射精、EV下降和EjD患者的汇总比例分别为18% (95% CI, 11-36%)、85% (95% CI, 81-89%)和24% (95% CI, 16-35%)。结论接受放射治疗的患者可能会经历射精方面的重大变化,如不射精、EV 和 EjD 减少。就这些潜在的副作用向他们提供咨询非常重要。

期刊介绍: Prostate Cancer and Prostatic Diseases covers all aspects of prostatic diseases, in particular prostate cancer, the subject of intensive basic and clinical research world-wide. The journal also reports on exciting new developments being made in diagnosis, surgery, radiotherapy, drug discovery and medical management. Prostate Cancer and Prostatic Diseases is of interest to surgeons, oncologists and clinicians treating patients and to those involved in research into diseases of the prostate. The journal covers the three main areas - prostate cancer, male LUTS and prostatitis. Prostate Cancer and Prostatic Diseases publishes original research articles, reviews, topical comment and critical appraisals of scientific meetings and the latest books. The journal also contains a calendar of forthcoming scientific meetings. The Editors and a distinguished Editorial Board ensure that submitted articles receive fast and efficient attention and are refereed to the highest possible scientific standard. A fast track system is available for topical articles of particular significance.
