Breast cancer survivors (BCS) often face unique challenges during and after treatment, including the onset of menopause-related symptoms. Genitourinary Syndrome of Menopause (GSM) is a common concern in BCS undergoing endocrine therapy (ET). It is a chronic condition caused by estrogen deficiency, leading to vaginal and urinary symptoms such as dryness, irritation, pain during intercourse, recurrent infections, and urinary urgency.
The prevalence of GSM in BCS varies widely depending on factors such as the type of ET, individual patient characteristics, and the duration of treatment. As such, the prevalence of GSM in BCS can range from 13% to 95.2%. A recent systematic review performed by part of the investigators of this study concludes that GSM is a significant problem for breast cancer patients. However, most studies lack a control group, limiting the results' validity. Therefore, this study aims to determine the extent of the GSM burden in BCS using a prospective, controlled cohort study. This study will compare breast cancer patients receiving endocrine therapy (ET) with those undergoing chemotherapy (CT), as CT may also induce GSM-like symptoms. In addition, a comparison will be made with healthy controls.
For this study, two groups of participants are included: women with breast cancer and a healthy control group without breast cancer. Within the breast cancer group, a distinction is made between women receiving chemotherapy only and women undergoing hormone therapy only. All participants complete questionnaires. The control group completes these questionnaires once, whereas women with breast cancer are asked to complete the same questionnaires at multiple time points during their treatment and follow-up. This longitudinal approach allows us to assess how potential symptoms evolve over the course of treatment. By comparing responses between both groups, a clearer understanding of which symptoms occur more frequently in women with breast cancer as a consequence of their treatment can be obtained.

| Questionnaires (NRS, DASS-21, EORTC QLQ-C30, EORTC QLQ-BR42, FSFI, FSDS-R) | Other | Primary objective: The study seeks primarily to provide a comprehensive overview of the burden of GSM in breast cancer patients receiving endocrine therapy (ET) or chemotherapy (CT) in comparison to a healthy control group. Secondary objective: The secondary aim of this study is to evaluate the extent of GSM-related symptoms in breast cancer patients and compare CT and ET. Furthermore, this study aims to evaluate the effect of GSM on the QoL, sexual health, and mental well-being of breast cancer patients. This study also seeks to analyze correlations between the extent of GSM, treatment, and patient characteristics. |
| Measure | Description | Time Frame |
|---|---|---|
| Vaginal dryness (NRS) | The Numeric Rating Scale (NRS) will be used to evaluate GSM-related vaginal dryness. The NRS is an 11-point scale ranging from 0 (none) to 10 (maximum severity). | From enrollment up till 12 months later. |
| Vaginal pruritus (NRS) | Description: The Numeric Rating Scale (NRS) will be used to evaluate GSM-related vaginal pruritus. The NRS is an 11-point scale ranging from 0 (none) to 10 (maximum severity). | From enrollment up till 12 months later. |
| Vaginal discharge (NRS) | The Numeric Rating Scale (NRS) will be used to evaluate GSM-related vaginal discharge. The NRS is an 11-point scale ranging from 0 (none) to 10 (maximum severity). | From enrollment up till 12 months later. |
| Vaginal hemorrhage (NRS) | The Numeric Rating Scale (NRS) will be used to evaluate GSM-related vaginal hemorrhage. The NRS is an 11-point scale ranging from 0 (none) to 10 (maximum severity). | From enrollment up till 12 months later. |
| Vaginal burning sensation (NRS) | The Numeric Rating Scale (NRS) will be used to evaluate GSM-related vaginal burning sensation. The NRS is an 11-point scale ranging from 0 (none) to 10 (maximum severity). | From enrollment up till 12 months later. |
| Measure | Description | Time Frame |
|---|---|---|
| Sexual Functioning Score | The Female Sexual Function Index (FSFI) is a multidimensional, self-reported questionnaire that evaluates the patient's sexual functioning. The questionnaire consists of 19 questions, divided into six subscales (sexual desire, sexual arousal, lubrication, orgasms, sexual gratification and pain during intercourse). The total score ranges from 2 (severely compromised sexual functioning) to 36 (excellent sexual functioning). |
| Measure | Description | Time Frame |
|---|---|---|
| General patient-, disease-, and treatment-related information | General and medical information will be collected through a short patient questionnaire in order to assess intrinsic risk factors (e.g. age and smoking history). Information regarding the disease- and treatment-related risk factors will be collected through medical records (e.g., tumour type and stage). | Baseline |
Inclusion Criteria:
Exclusion Criteria:
This study will only include biologically female patients, as the study populations consist of breast cancer patients experiencing Genitourinary Syndrome of Menopause (GSM). The biologically male breast cancer patients are not appropriate for this study, related to menopause.

| From enrollment up till 12 months. |
| Sexual Distress Score | The multidimensional, self-reported Female Sexual Distress Scale-Revised 2005 (FSDS-R) questionnaire will be used to evaluate the patient's sexual distress. This questionnaire consists of 13 items scored from 0 (never occurring) to 4 (always occurring). A score of 11 or more effectively discriminates between patients with female sexual distress and patients without distress. | From enrollment up till 12 months. |
| Quality of Life Score | The European Organization for Research and Treatment for Cancer Quality of Life Questionnaires (EORTC QLQ-C30) will be used to assess the patients' quality of life. The EORTC QLQ-C30 consists of 30 questions. These include five functional scales, three symptom scales, a global health status/quality of life (QoL) scale, and six single items. All of the scales and single-item measures range in score from 0 to 100. A high score for a functional scale represents a high/healthy level of functioning, a high score for the global health status/QoL represents a high QoL, but a high score for a symptom scale/item represents a high level of symptomatology/problems. | From enrollment up till 12 months later. |
| Quality of Life Score - Breast Cancer Specific | The European Organization for Research and Treatment for Cancer Quality of Life Questionnaires (EORTC QLQ-BR42) will be used to assess breast cancer-specific quality of life. The EORTC QLQ-BR42 consists of 42 questions. All of the scales and single item measures range in score from 0 to 100. A high score for the Body Image, Sexual Functioning and Breast Satisfaction scales and for the Future Perspective and Sexual Enjoyment single items represents a high level of functioning, whereas a high score for the Systemic ChemoTherapy Side Effects, Endocrine Symptoms, Arm Symptoms, Breast Symptoms, Hand/foot symptoms/neuropathy, Skeletal Scale and Vaginal Symptoms scales and for the Weight Gain single item represents a high level of symptomatology or problems. | From enrollment up till 12 months later. |
| Mental Health | The mental health of the patients will be determined using the Depression Anxiety Stress-Scale (DASS-21). Three different scores will be calculated: depression (0-21), anxiety (0-21) and stress (0-18). A lower score indicates a normal mental health, while a higher score indicates extremely severe depression, anxiety and/or stress. | From enrollment up till 12 months later. |
