Brief Summary

Breast cancer has a high impact, affecting 2.3 million women worldwide in 2022. In Spain, there were 40,203 new cases in 2023. In addition to the economic and social costs, patients suffer genitourinary dysfunctions due to cancer treatments. Genitourinary Menopausal Syndrome (GUS) affects 50% of menopausal women, with a higher prevalence in women with breast cancer. This study aims to compare the effectiveness of radiofrequency (RF) and pelvic floor muscle exercise (PFMT) in the treatment of pelvic dysfunction associated with GUS in breast cancer patients. A randomised, double-blind clinical trial will be conducted in collaboration with the Association of Women Affected by Breast Cancer of Elche and Region) and the CEU Cardenal Herrera University. Women diagnosed with breast cancer and pelvic dysfunction will participate, divided into three groups: one will receive PFMT, one will receive RF and one will receive PFMT+RF therapy. Both techniques are expected to improve the quality of life of patients, where RF could offer additional benefits due to its proven effectiveness in the treatment of vaginal dryness and dyspareunia. The expected results will contribute to more effective and less invasive treatment protocols. The project presented has the potential to positively impact the health and well-being of women with breast cancer, reducing the symptoms associated with the disease and its treatment, and improving their quality of life.

Study Arms (2)

Temperature after apply RF in capacitive electrical transfer mode (Capernergy® device model C500)

EXPERIMENTAL

It is a device designed mainly to address dysfunctions in the urogynecological area, where the increase in tissue temperature is regulated by a temperature sensor, with 3 frequencies (0.8MHz, 1MHz and 1.2 MHz) that will allow different tissue depths to be addressed, and a power of 310w. This device consists of two electrodes: an active capacitive electrode to be placed in the vaginal area with a probe cover and water-soluble gel and another dispersive electrode or return plate to be positioned in the lumbosacral region.

Device: manometry through the PHENIX series device (model: PHENIX LIBERTY; manufacturer: ELECTRONIC CONCEPT LIGNON INNOVATION, Montpelier, France).Diagnostic Test: PFIQ-20 questionnaire (Pelvic Floor Impact Questionnaire Short Form)Diagnostic Test: ICIQ-SF (International Consultation on Incontinence Questionnaire - Short Form)Diagnostic Test: Sandvik's testDiagnostic Test: vaginal health index (VHI)Diagnostic Test: Visual analogue scale (VAS)Diagnostic Test: Body Image Scale (S-BIS)Diagnostic Test: Likert's scale questionnaireDiagnostic Test: Oxford's ScaleDiagnostic Test: Sexual function and self-esteem

PFMT

EXPERIMENTAL

The PFMT will consist of a targeted programme, with a protocol of CORE and pelvic floor exercises established based on the assessment of the patients' strength, endurance and fatigue, with a frequency of twice a week led by a physiotherapist and a duration of 45 minutes each day and a period of 16 weeks.It will be carried out in groups of 8 people and accompanied by a physiotherapist experienced in therapeutic exercise. Each session will consist of exercises to activate the pelvic floor muscles in isolation and in association with the CORE muscles, both static and dynamic.

Interventions

For this manometry the air probe, connected to the Phenix biofeedback system, covered by a latex probe cover lubricated with gel, will be used. In the procedure, the labia majora are opened with one hand and slowly rotated into the vagina while holding the back of the manometric probe with the other hand. Basal tone in g will be measured prior to pelvic floor muscles force measurements. The manometry probe will extract pelvic floor pressure signals by measuring both your basal tone and the maximum pressure held for 10 seconds in three measurements, the average of the three being calculated at the command, 'contract as hard as you can for as long as possible'.

PFMTTemperature after apply RF in capacitive electrical transfer mode (Capernergy® device model C500)

a four-question self-administered questionnaire that identifies individuals with urinary incontinence by assessing frequency, severity and impact on quality of life. It is composed of five questions assessing frequency, severity and impact of UI, plus a set of eight self-diagnostic items related to UI situations experienced by patients. The maximum sum of the response values indicates a score of 21 points, referring to the high impact of UI on an individual's life.

this index consists of a graduated scale from 1 to 5 for each item (vaginal elasticity, fluid volume, pH, epithelial integrity and moisture).Vaginal elasticity ranges from 1 (no elasticity) to 5 (excellent elasticity), assessed by distension of the mucosa on palpation and speculum placement. The volume of fluid, assessed during inspection, varies between 1 (no discharge) and 5 (normal discharge) (white flocculent). The integrity of the epithelium varies between 1 (petechiae already detected on inspection) and 5 (non-friable tissue and normal mucosa). Moisture ranges from 1 (no moisture detected on inspection and presence of inflamed mucosa) to 5 (normal moisture). The pH will be quantified using a pH indicator strip between 0 and 14 (MColorpHast™-PH indicator strips) to be placed directly on the right lateral vaginal wall for one minute, giving 1 point for pH 6.1, 2 for pH 5.6-6.0, 3 for pH 5.1-5.5, 4 for pH 4.7-5.0 and 5 for pH ≤ 4.6. The sum of all items represents the vaginal health

This scale allows the intensity of pain described by the patient to be measured with maximum reproducibility between observers. It consists of a horizontal line of 10 centimetres, at the ends of which are the extreme expressions of a symptom. At the left end is the absence or lowest intensity and at the right end the highest intensity. The patient is asked to mark on the line the point that indicates the intensity of the pain during sexual intercourse and it is measured with a millimetres ruler. The intensity is expressed in centimetres or millimetres. The rating will be: 1 Mild pain if the patient scores the pain as less than 3; 2 Moderate pain if the rating is between 4 and 7; 3 Severe pain if the rating is equal to or greater than 8.

It consists of 10 items assessing various dimensions of body image in cancer patients, evaluating: affective, behavioural and cognitive. The items are scored on a four-point scale (0: not at all; 1: a little; 2: quite a lot; 3: a lot) with a maximum possible score of 3 points. The higher the score, the higher the body image problem. Its brevity facilitates rapid assessment in both clinical and research settings. It shows a stable factor structure between samples, and good psychometric properties with high reliability (Cronbach's alpha=0.93), suggesting that it is a suitable and useful measure for assessing body image in breast cancer patients.

five-point Likert scale for satisfaction with treatment to be classified as: 1 (very dissatisfied), 2 (dissatisfied), 3 (no change), 4 (satisfied), 5 (very satisfied). Women who miss any of the RF sessions and/or whose attendance at the face-to-face physiotherapy sessions (RF and/or PFMT) does not reach 80% will be considered as not complying with the study protocol and their participation will be terminated, although they will be included in the analysis (by intention to treat).

Oxford's ScaleDIAGNOSTIC_TEST

It allows the contractile capacity of the pelvic floor muscles to be assessed. It scores from 0 to 5, as follows: if there is no contraction it is 0, if the contraction is very weak it is 1, if the contraction is weak it is 2, if the contraction is moderate/with tension/and maintained it is 3, if the contraction is good and maintains tension with resistance it is 4, and if the contraction is strong and maintains tension against a resistant force it is 5.
