Study Purpose

To evaluate a group cognitive-behavioral intervention to alleviate menopausal symptoms (hot flushes [HF] and/or night sweats [NS]) in women who have had treatment for breast cancer.

Intervention Characteristics/Basic Study Process

Following a two-week daily diary assessment, patients were offered six 90-minute weekly sessions of group cognitive-behavioral therapy (CBT). CBT included:  information and discussion about menopausal symptoms; monitoring and modifying stimulants that precipitate symptoms; relaxation and paced breathing; and techniques to reduce stress and manage HF, NS, and sleep. The primary outcome measures were HF frequency and HF problem rating. Secondary outcomes included scores on the Women’s Health Questionnaire (WHQ) and scores pertaining to health-related quality of life (HRQOL) as measured by the SF-36®. Beliefs about HF were monitored to examine the effects of CBT. 

Sample Characteristics

  • The study was comprised of 17 women receiving group CBT.
  • Mean age was 53.7 years (range 46–65).
  • Of the patients, 12 (71%) had undergone breast-conserving surgery; 3 (18%), modified radical mastectomy; 9 (53%), chemotherapy; 14 (82%), radiotherapy; and 12 (71%) were taking adjuvant hormonal therapies (11 were taking tamoxifen; 1 was taking anastrozole).
  • At diagnosis, seven patients (41%) were premenopausal, six (35%) were in the early or late transition stage of menopause, and four (24%) were in the early or late postmenopausal stage.
  • Average time since diagnosis was 23.2 months.
  • Average duration of HF and NS was 2.1 years.
  • Patients were treated in groups (of six, six, and five members); 12 women (59%) attended all six sessions, three women attended five sessions, and two attended three sessions. The majority (83%) completed all assessments.

Setting

  • Multisite
  • Outpatient
  • Clinic staff recruited patients by using a database at two breast units in London, England.

Phase of Care and Clinical Applications

  • Patients were undergoing the transition phase of care:  after initial treatment and completion of chemotherapy and/or radiotherapy and with or without hormone replacement therapy.
  • The study has clinical applicability for late effects and survivorship.

Study Design

The study was a single-group, exploratory trial with pre- and posttreatment assessment after six weeks and three months.

Measurement Instruments/Methods

  • Hot Flush Frequency and Problem Rating Scale (HFRS) 
  • WHQ
  • Hot Flush Beliefs Scale (HFBS)
  • SF-36® HRQOL ratings
  • Daily diaries
     

Results

  • Weekly frequency of HF and NS was reduced from 75.7 to 46.9 (p < 0.03) at the posttreatment measure to 38.3 (p < 0.02) at the three-month follow-up. This change represents a 38% reduction at posttreatment and a 49% reduction at the three-month follow-up.
  • Problem rating was reduced from 6.3 to 3.4 at posttreatment (p < 0.0001) and to 2.6 at follow-up (p < 0.0001).
  • Depressed mood and anxiety significantly decreased from assessment to posttreatment (p < 0.02), and reductions were maintained at the three-month follow-up (p < 0.03).
  • Sleep improved significantly (p < 0.003).
  • Subscales of the SF-36® showed other significant improvements:  emotional role limitation (p < 0.0001), mental health (p < 0.01), energy/vitality (p < 0.0001), and general health (p < 0.003).
  • Total scores on the HFBS decreased significantly, from 28.2 to 22.4 at posttreatment (t = 3.77; df = 16; p < 0.002), and were maintained at 22.7 at follow-up (t = 4.34; df = 16; p < 0.001). These reductions reflected a significant change in beliefs.

Conclusions

  • Results suggest that CBT delivered in groups might offer a viable option for women with troublesome, undertreated, menopausal symptoms following breast cancer treatment, but further controlled trials are needed.
  • CBT is consistent with the preferred treatment of women surveyed.
  • Improvements continued after treatment, which may reflect the skills-learning aspect of CBT. HF and NS decreased, as did depressed mood and anxiety.
  • Sleep improved, as reported by changes in WHQ ratings.
  • Results showed no signficant improvement in specific dimensions of HRQOL, particularly emotional role limitation, energy/vitality, or mental health.

Limitations

  • The study had a small sample size, with less than 30 patients.
  • The study is of limited generalizability.
  • The main limitations of the study were lack of controls for placebo effects, attention, and spontaneous remission.
     

Nursing Implications

Nurses could be trained to conduct structured, interactive, group CBT with individual treatment goals. A randomized, controlled trial is recommended for further investigation.
