- Brief Summary
Vaginal stenosis is one of the most prevalent side effects of pelvic radiation, affecting about one third of women. In this randomized controlled trial, the effect of a pelvic physiotherapy protocol on an incidence rate of vaginal stenosis in women with gynecological cancer undergoing gynecological brachytherapy. In addition, the investigators will explore an improvement in quality of life, sexuality, and contractile function of the pelvic floor muscles.
- Detailed Description
Tis study will be conducing in a reference hospital to oncology treatment were mane patients with gynecologic cancer are management on radiotherapy services. The aim of this work is evaluated the effects of the pelvic physiotherapy (PP) on the more prevalent constriction pathology (vaginal stenosis) secondary to the brachytherapy. The PP will be conduced by three months after the radiotherapy starts and the incidence of the vaginal stenosis will be compared with a control group throughout six months of fallow-up.

Group Intervention Description Pelvic physiotherapy (PP) Pelvic Physiotherapy Pelvic Physiotherapy include daily pelvic floor muscle training (PFMT). PFMT starts at first session of the brachytherapy and will be conduced during the twelve weeks treatment. Pelvic physiotherapy (PP) Standard care (SC) Pelvic Physiotherapy include daily pelvic floor muscle training (PFMT). PFMT starts at first session of the brachytherapy and will be conduced during the twelve weeks treatment. Stander Care (SC) Standard care (SC) The stander care (SC) includes a guideline for gynecological cancer patients under radiotherapy/brachytherapy: 1) daily vaginal dilator therapy (10 to 15 minutes); and 2) usual care management. This SC starts at first session of the brachytherapy and will be conduced during the twelve weeks treatment.
- Primary Outcome Measures
Name Time Method Vaginal Stenosis With completion of the study, predicted 15 months after the start of the study. Vaginal stenosis will be evaluated before the first brachytherapy and twelve months after. Considered according to the study of Kirchheiner et al., (2016) that used the Common Terminology Criteria for Adverse Events (CTCAE v3.0). Vaginal stenosis will also be considered as the narrowing of the vaginal canal that makes it impossible to introduce the number 1 acrylic gynecological speculum through the vaginal introitus.
- Secondary Outcome Measures
Name Time Method Quality of life With completion of the study, predicted 15 months after the start of the study. The quality of live will be evaluated before the first brachytherapy and twelve months after through the application of the Quality of Life questionnaire European Organization for Research and Treatment of Cancer - EORTC QLQ-C30.
Sexuality With completion of the study, predicted 15 months after the start of the study. The sexuality will be evaluated before the first brachytherapy and twelve months after through the application of the questionnaire The Female Sexual Function Index (FSFI).
Muscle activity and contractile function of the pelvic floor With completion of the study, predicted 15 months after the start of the study. Measurement of pelvic floor activity will be evaluated before the first brachytherapy and twelve months after through surface electromyography (EMG), which is able to record the extracellular bioelectric activity generated by muscle fibers, through the electromyographic biofeedback Miotool 400 from Miotec.
