Menopause symptoms and quality of life in women aged 45 to 65 years with and without breast cancer.
OBJECTIVE
To compare the prevalence of menopause symptoms, sexual activity, and quality of life in women with and without breast cancer.


METHODS
A cross-sectional study using one group for comparison was conducted on women aged 45 to 65 years who had not received hormone therapy or tamoxifen during the last 6 months. Participants were recruited from the Menopause and Breast Cancer Outpatient Facilities. One hundred eighty-two women were included, 97 with breast cancer and 85 without breast cancer. Sociodemographic and clinical features and prevalence of menopause symptoms were assessed. The quality of life was assessed by the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) questionnaire. To compare sociodemographic and clinical features between groups, the Student's t test or Fisher exact test was used. Multiple logistic regression and linear regression models were used to control for potential confounding variables.


RESULTS
The mean age of participants with breast cancer was 53.2 +/- 6.2 years, and the mean age of those without cancer was 57.8 +/- 4.9 years (P < 0.01). Age at menopause was 47.2 +/- 5.1 years and 47.4 +/- 4.9 years for women with and without breast cancer (P = 0.76), respectively. Approximately one-fourth of women with breast cancer and 4.7% of women without cancer were premenopausal (P < 0.01). The prevalence of menopause symptoms was similar between the groups. Women with breast cancer reported less sexual activity (51.5%) than women without cancer (62.4%) (P < 0.01). Quality of life scores were good in both groups. There was a significant difference regarding physical functioning, with a median score of 90 for the cancer group and 75 for the group without cancer (P < 0.01).


CONCLUSIONS
The prevalence of menopause symptoms was similar in women with and without breast cancer. Sexual activity was less frequent in women with breast cancer. Quality of life was good in women from both groups, although women with breast cancer had the highest level of physical functioning.
