Functional Changes of the Genitourinary and Gastrointestinal Systems before and after the Treatment of Endometrial Cancer-A Systematic Review

Simple Summary Endometrial cancer is currently one of the most common gynecological cancer and accounts for around 5% of all female cancers. The treatment strategy most often includes surgery and adjuvant radiation therapy. Thanks to the high effectiveness of used treatment methods, the patients can live longer lives. Unfortunately their quality of life can be negatively affected by side effects resulting from weakening pelvic floor such as urinary incontinence, pelvic organ prolapse and fecal incontinence. In our paper we analyzed the studies published between 2010 and 2020 that touch upon the prevalence and management of pelvic floor dysfunction in endometrial cancer patients. Our results show increase in the incidence of pelvic floor disorders after various forms of endometrial cancer treatment and the need for more good quality research in the subject to be able to provide patients with holistic care focused on minimizing treatment side effects and prioritizing their quality of life. The incidence of endometrial cancer (EC), which coexists with such civilization diseases as diabetes, obesity or hypertension, is constantly increasing. Treatment includes surgery as well as brachytherapy, teletherapy, rarely chemotherapy or hormone therapy. Due to the good results of the treatment, the occurrence of side effects of therapy becomes a problem for the patients. One of the large groups of side effects includes the pelvic organ prolapse, urinary and fecal incontinence. The aim of this study was to present current knowledge on the occurrence of pelvic floor dysfunction in women treated for EC. A literature review was conducted in the PubMED and WoS databases, including articles on pelvic floor dysfunction in women with EC. PRISMA principles were followed in the research methodology. A total of 1361 publications were retrieved. Based on the inclusion and exclusion criteria, 24 papers were eligible for the review. Mostly retrospective studies based on different questionnaires were evaluated. No prospective studies were found in which, in addition to subjective assessment, clinical examination and objective assessment of urinary incontinence were used. Studies show a significant increase in the incidence of pelvic floor disorders, including urinary incontinence, after various forms of EC treatment. We believe that assessment of complications after endometrial cancer treatment is clinically relevant. The review emphasizes the importance of programming prospective studies to prevent and address these disorders at each stage of oncologic treatment.
