Background: Breast cancer is the most common form of cancer among women in the Netherlands. Approximately 11,000 women are diagnosed with breast cancer annually, of whom about 30% are below 50 years of age. Premenopausal women with breast cancer treated with chemotherapy or hormonal therapy may experience a premature onset of the menopause. Estrogen deficiency following adjuvant treatments leads to primary endocrine symptoms, including vasomotor and urogenital problems. Secondary symptoms include insomnia due to night sweats, dyspareunia due to vaginal dryness, weight gain, and psychological distress. The symptoms resulting from accelerated estrogen withdrawal can be pronounced and severe, and may adversely affect women's sexual functioning, body image, and overall HRQL. Healthy women who enter natural menopause are often prescribed hormone replacement therapy (HRT) to alleviate vasomotor and sexual symptoms. However, due to possible tumor-promoting effects, HRT is contraindicated for patients with a history of breast cancer. For these women, non-hormonal medications are frequently prescribed to treat vasomotor symptoms. Although these medications have been shown to yield moderate symptom relief, they also have a number of bothersome side effects. To alleviate urogenital symptoms, local vaginal moisturizing or estrogen cream is often prescribed. There is growing evidence that cognitive behavioral therapy (CBT) including relaxation techniques, and physical exercise may effectively reduce vasomotor symptoms in naturally occurring menopause. CBT and relaxation techniques are aimed primarily at the modification of precipitants of hot flushes and at stress management. Physical exercise on a regular basis affects neurotransmitters, which regulate central thermoregulation.
Purpose: The proposed study will evaluate the efficacy of a supportive intervention program in alleviating menopausal symptoms, improving sexual functioning and enhancing the quality of life of younger women (< 50 years) with breast cancer who have become prematurely menopausal as a result of their treatment. Specifically, the study will evaluate CBT including relaxation (A), physical exercise (B), and a combination of A and B.
Plan of investigation: This multicenter study will employ a prospective, full-factorial design. In total, 325 consenting women will be randomized to group A, group B, group AB or a usual care, 'waiting list' control group (N = 81-81 per group). Upon completion of the study, the patients assigned to the control group will be given the opportunity to undergo either the A or B intervention program. The program will begin with a structured assessment of the target symptoms: hot flushes, night sweating and vaginal dryness. The overriding goal of the intervention is to provide symptomatic women with information skills and support to manage their symptoms more effectively. For group A, the intervention will consist of 6 weekly group CBT sessions of 1.5 hours, of 15 minutes of daily homework and a booster session at 3 months. The CBT will focus on understanding and self-control of menopausal symptoms. Relaxation techniques (paced respiration and muscle relaxation) will focus on the reduction of sympathetic nervous system activity, and are expected to have a positive impact on the frequency and intensity of hot flushes. For group B, the intervention will be an individually tailored, 12 week home-based physical exercise program of 2.5-3 hours per week, with instructions provided in-clinic on 2 occasions, and telephone support on 2 additional, interim occasions. The physical exercise program is intended to enhance fitness levels, in general, and to improve thermoregulation specifically related to hot flushes. Group AB will receive both the CBT and exercise program elements. Women allocated to the intervention groups will be asked to complete a battery of questionnaires assessing menopausal symptoms (the primary outcome), sexuality, body- and self-image, psychological distress and generic HRQL prior to the start of the program (baseline, T0), at 12 weeks (T1) and at 6 months follow-up (T2). Women allocated to the control group will complete the same questionnaire battery at parallel points in time.
Results/ relevance: If demonstrated to be effective, the availability of a structured supportive intervention program (modules A, B or AB) will be a welcome addition to regular medical care offered to breast cancer patients with treatment-induced menopause. It is anticipated that such a program will have direct benefit in terms of symptoms relief and the improvement of patients' HRQL.
