Purpose: Multimodal therapy has improved survival in genitourinary rhabdomyosarcoma, a rare pediatric cancer. However, little is reported regarding postoperative complications and long-term urinary and sexual function and quality of life. Materials and Methods: We reviewed records from 1970-2018 to identify patients with genitourinary rhabdomyosarcoma of the bladder, prostate, pelvis, vagina, and uterus. We assessed modes of therapy, and if surgical, the type of resection, reconstruction, and reoperation. Primary outcomes included urinary continence, urinary tract infection occurrence, and stone formation. We also surveyed patients older than 18 years for urinary and sexual function.Results: Fifty-one patients were identified for the post-treatment outcomes cohort. All received chemotherapy, 46 (90.2%) underwent surgery, and 34 (67%) received radiation. Twenty-nine patients (56.9%) received trimodal therapy, 17 (33.3%) received chemotherapy/surgery, and 5 (9.8%) received chemotherapy/radiation. Twenty-six had up-front radical surgery (with staged continence mechanism creation); these patients had higher rates of continence, similar rates of urinary tract infection, and higher rates of stone formation compared to those who were organspared. A third (4/12) of organ-spared patients underwent additional corrective surgery. Thirty patients with genitourinary rhabdomyosarcoma were surveyed and 14 responded to questionnaires. Overall, urinary complaints were mild, but both male and female respondents reported significant sexual dysfunction. Conclusions: Organ-sparing treatment was more likely to predispose patients to high rates of additional reconstructive surgery due to compromised urological function. In survey results, both men and women reported poor sexual function, but the majority of patients remained satisfied with their urinary function.
IntroductionApproximately one million prostate biopsies are performed annually in the USA, and most are performed using a transrectal approach under local anaesthesia. The risk of postbiopsy infection is increasing due to increasing antibiotic resistance of rectal flora. Single-centre studies suggest that a clean, percutaneous transperineal approach to prostate biopsy may have a lower risk of infection. To date, there is no high-level evidence comparing transperineal versus transrectal prostate biopsy. We hypothesise that transperineal versus transrectal prostate biopsy under local anaesthesia has a significantly lower risk of infection, similar pain/discomfort levels and comparable detection of non-low-grade prostate cancer.Methods and analysisWe will perform a multicentre, prospective randomised clinical trial to compare transperineal versus transrectal prostate biopsy for elevated prostate-specific antigen in the first biopsy, prior negative biopsy and active surveillance biopsy setting. Prostate MRI will be performed prior to biopsy, and targeted biopsy will be conducted for suspicious MRI lesions in addition to systematic biopsy (12 cores). Approximately 1700 men will be recruited and randomised in a 1:1 ratio to transperineal versus transrectal biopsy. A streamlined design to collect data and to determine trial eligibility along with the two-stage consent process will be used to facilitate subject recruitment and retention. The primary outcome is postbiopsy infection, and secondary outcomes include other adverse events (bleeding, urinary retention), pain/discomfort/anxiety and critically, detection of non-low-grade (grade group ≥2) prostate cancer.Ethics and disseminationThe Institutional Review Board of the Biomedical Research Alliance of New York approved the research protocol (protocol number #18-02-365, approved 20 April 2020). The results of the trial will be presented at scientific conferences and published in peer-reviewed medical journals.Trial registration numberNCT04815876.
