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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
