Pelvic floor muscle assessment by digital palpation and translabial ultrasound of women with cervical or endometrial cancer after pelvic radiotherapy: a cross-sectional study

We hypothesized that anatomical changes in the pelvic floor muscles (PFM) could be detected using four-dimensional translabial ultrasound (4D TLUS) in patients with cervical (CC) or endometrial cancer (EC) who underwent pelvic radiotherapy (RT) as digital palpation may present sensitivity limitations. This was a cross-sectional study that included 64 women (26 with CC and 38 with EC). PFM function was assessed by digital palpation, grading muscle strength according to the Modified Oxford Scale and by 4D TLUS. Ultrasonographic variables were: levator plate angle, hiatal area, puborectalis muscle thickness, puborectalis strain and levator ani muscle integrity. These variables were also correlated with clinical and sociodemographic data from all these patients. A 5% significance level was adopted. When assessed by digital palpation, no significant difference was found in PFM strength between women with CC and those with EC (p = 0.747). However, when assessed by 4D TLUS, women with CC presented greater thickening of the left (p = 0.039) and right (p = 0.014) lower portion of the puborectalis muscle during PFM contraction compared to those with EC. After pooling the groups, higher cancer staging (p = 0.028) was associated with smaller narrowing in the symphysis-levator distance, and shorter RT finishing duration (< 60 months) was associated with higher thickening in the left (p = 0.029) and right (p = 0.013) upper portion of the puborectalis muscle during PFM contraction as well as a shorter menopause duration (p = 0.007 and p = 0.002, respectively). Anatomical changes in the puborectalis muscle during PFM contraction were detected by 4D TLUS within gynecological cancer patients after pelvic RT.

Vaginal stenosis in women with cervical or endometrial cancer after pelvic radiotherapy: a cross-sectional study of vaginal measurements, risk for sexual dysfunction and quality of life

Radiotherapy (RT) for cervical (CC) and endometrial cancer (EC) is known to lead to vaginal stenosis (VS), but the comparison between vaginal anatomical measurements and the risk of sexual dysfunction presents a wide variety of results among the literature. Thus, we sought to assess the prevalence of VS, vaginal measurements, sexual dysfunction and QOL in women with CC and EC submitted to pelvic RT with or without previous surgery. Cross-sectional study that included 61 women with CC and 69 with EC. VS was classified by the Common Terminology Criteria for Adverse Effects version 5.0 (CTCAE v5.0), sexual function by the validated Female Sexual Function Index (FSFI) and QOL by the validated World Health Organization questionnaire (WHOQOL-BREF). Acrylic cylinders were used for vaginal measurements. Uni-/multivariate analyses to address factors associated with VC in both groups were performed. The prevalence of VS was 79% and 67% within patients with CC and EC, respectively. Vagina length was decreased in both groups without statistical difference (7.2 ± 1.7 vs. 6.6 ± 1.8;p = 0.072). Vaginal diameter was significantly higher (p = 0.047) in women with EC (25.4 ± 6.3) than in those with CC (23.1 ± 5.7). Sexual dysfunction was highly prevalent for both CC and EC (88% vs. 91%; p = 0.598). There was no difference in all WHOQOL-BREF domains between women with CC and EC. VS is highly prevalent in CC and EC patients, with vaginal length decreased in both groups but with a higher vaginal diameter in those with EC. Nevertheless, sexual dysfunction is highly prevalent in both groups.

The Effects of Hysterectomy on Urinary and Sexual Functions of Women with Cervical Cancer: A Systematic Review

Abstract Objective This systematic review aims at describing the prevalence of urinary and sexual symptoms among women who underwent a hysterectomy for cervical cancer. Methods A systematic search in six electronic databases was performed, in September 2019, by two researchers. The text search was limited to the investigation of prevalence or occurrence of lower urinary tract symptoms (LUTS) and sexual dysfunctions in women who underwent a hysterectomy for cervical cancer. For search strategies, specific combinations of terms were used. Results A total of 8 studies, published between 2010 and 2018, were included in the sample. The average age of the participants ranged from 40 to 56 years, and the dysfunctions predominantly investigated in the articles were urinary symptoms (n = 8). The rates of urinary incontinence due to radical abdominal hysterectomy ranged from 7 to 31%. The same dysfunction related to laparoscopic radical hysterectomy varied from 25 to 35% and to laparoscopic nerve sparing radical hysterectomy varied from 25 to 47%. Nocturia ranged from 13%, before treatment, to 30%, after radical hysterectomy. The prevalence rates of dyspareunia related to laparoscopic radical hysterectomy and laparoscopic nerve sparing radical hysterectomy ranged from 5 to 16% and 7 to 19% respectively. The difficulty in having orgasm was related to laparoscopic radical hysterectomy (10 to 14%) and laparoscopic nerve sparing radical hysterectomy (9 to 19%). Conclusion Urinary and sexual dysfunctions after radical hysterectomy to treat cervical cancer are frequent events. The main reported disorders were urinary incontinence and dyspareunia.
