The Difference in Hot Flash Score (Frequency and Severity) Between Baseline (Week 1) and Week 9 [ Time Frame: Week 1 and Week 9 ]
Hot flash severity were graded from 1 to 4, as they range from mild, moderate, severe, or very severe. A hot flash score is defined by multiplying the daily frequency with the average hot flash severity. These scores are aggregated into average weekly hot flash activity scores for each patient.

  • Change From Baseline to Week 9 for PSQI Global Score [ Time Frame: Baseline and Week 9 ]
    The Pittsburgh Sleep Quality Index (PSQI) has 19 items and seven component scales: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep-wake disturbances, use of sleep medication, and daytime dysfunction. The scoring algorithm yields seven component scales on 0-3 scales which are summed to produce a global score on a 0-21 scale with higher values representing more severe sleep difficulty. The global score is translated into 0-100 scale with high values representing best quality of life (QOL). The habitual sleep efficiency component and global score was estimated using the worst-case scenarios for the values that were provided for PSQI question 4. Change from baseline to week 9 was calculated by subtracting the baseline scores from the scores at week 9.
  • Change From Baseline to Week 9 on Blood Pressure Measurement [ Time Frame: Baseline and Week 9 ]
    Participants were taught home monitoring of blood pressure and provided with the sphygmomanometer. The measurements data were recorded on the Blood Pressure Measurement log. Change from baseline to week 9 was calculated by subtracting the baseline measurement from the measurement at week 9.
  • Change From Baseline to Week 9 for POMS Total Score and Subscales [ Time Frame: Baseline and Week 9 ]
    Profile of Mood States (POMS) measures a variety of mood states including tension/anxiety, depression/dejection, anger/hostility, vigor/activity, fatigue/inertia and confusion/bewilderment. Each subscale consist of 5 items with a 5 points-scale (0=not at all, 1=a little, 2=moderately, 3=quite a bit and 4=extremely). The subscale scores were the sum of all five items. The total score was the sum of all subscale scores. The scores were then transformed into a 100-point scale with higher numbers indicating best quality of life (QOL). Change from baseline to week 9 was calculated by subtracting the baseline scores from the scores at week 9.
  • Pearson Correlation Coefficients for Changes in Hot Flash Scores From Baseline to Week 9 With Changes in POMS Total Score and Subscales From Baseline to Week 9 [ Time Frame: Baseline and Week 9 ]
    Profile of Mood States (POMS) measures a variety of mood states including tension/anxiety, depression/dejection, anger/hostility, vigor/activity, fatigue/inertia and confusion/bewilderment. Each subscale consist of 5 items with a 5 points-scale (0=not at all, 1=a little, 2=moderately, 3=quite a bit and 4=extremely). The subscale scores were the sum of all five items. The total score was the sum of all subscale scores. The scores were then transformed into a 100-point scale with higher numbers indicating best quality of life (QOL). Change from baseline to week 9 was calculated by subtracting the baseline scores from the scores at week 9. The correlation was estimated using Pearson correlation coefficients. The assessment of the Pearson Correlation Coefficients was the pre-specified Secondary outcome, and not the underlying changes in the POMS scores.
  • Change From Baseline to Week 9 for BFI Fatigue Scores [ Time Frame: Baseline and Week 9 ]
    Brief Fatigue Inventory (BFI) consist of 3 items that assess the severity of fatigue and 6 items that assess the impact of fatigue on daily functioning in a 10-points scale with 0 as no fatigue or does not interfere with daily functioning and 10 as bad fatigue or completely interferes. The scores for the six items were summed up to form a total interference score. The linear analogue scale of fatigue was a 10-points scale with 0 as no fatigue and 10 as bad fatigue. All scores were then transformed into 0 to 100 scale, with 100 as less fatigue/less interference. Change from baseline to week 9 was calculated by subtracting the baseline scores from the scores at week 9.
  • Pearson Correlation Coefficients for Changes in Hot Flash Scores From Baseline to Week 9 With Changes in BFI Fatigue From Baseline to Week 9 [ Time Frame: Baseline and Week 9 ]
    Brief Fatigue Inventory (BFI) consist of 3 items that assess the severity of fatigue and 6 items that assess the impact of fatigue on daily functioning in a 10-points scale with 0 as no fatigue or does not interfere with daily functioning and 10 as bad fatigue or completely interferes. The scores for the six items were summed up to form a total interference score. The linear analogue scale of fatigue was a 10-points scale with 0 as no fatigue and 10 as bad fatigue. All scores were then transformed into 0 to 100 scale, with 100 as less fatigue/less interference. Change from baseline to week 9 was calculated by subtracting the baseline scores from the scores at week 9. The correlation was estimated using Pearson correlation coefficients. The assessment of the Pearson Correlation Coefficients was the pre-specified Secondary outcome, and not the underlying changes in the BFI fatigue items scores.
  • Change From Baseline to Week 9 for Symptom Distress Diary [ Time Frame: Baseline and Week 9 ]
    Symptom Experience Diary is a self-report diary of expected side effects from controlled breathing on 10-points scale with 10 represents symptoms all the time. Individual item scores were then transformed into 0 to 100 scale, with 100 indicates best quality of life (QOL). Change from baseline to week 9 was calculated by subtracting the baseline scores from the scores at week 9.
  • Pearson Correlation Coefficients for Changes in Hot Flash Scores From Baseline to Week 9 With Changes in Symptom Experience Diary From Baseline to Week 9 [ Time Frame: Baseline and Week 9 ]
    Symptom Experience Diary is a self-report diary of expected side effects from controlled breathing on 10-points scale with 10 represents symptoms all the time. Individual item scores were then transformed into 0 to 100 scale, with 100 indicates best quality of life (QOL). Change from baseline to week 9 was calculated by subtracting the baseline scores from the scores at week 9. The correlation was estimated using Pearson correlation coefficients. The assessment of the Pearson Correlation Coefficients was the pre-specified Secondary outcome, and not the underlying changes in the Symptom Experience Diary item scores.

Three Different Programs of Paced Breathing in Treating Hot Flashes in Women
Paced Breathing for Hot Flashes: A Randomized Phase II Study

RATIONALE: Paced breathing may be an effective way to reduce the number and severity of hot flashes in women who have survived breast cancer.

PURPOSE: This randomized phase II trial is comparing three different programs of paced breathing to see how well they work in treating hot flashes in women.

OBJECTIVES:

  • To assess feasibility and obtain initial estimates of efficacy of three different programs of paced breathing (15 minutes once a day at 6 breaths/minute vs 15 minutes twice a day at 6 breaths/minute vs 10 minutes once a day at 14 breaths/minute) on the frequency and severity of hot flashes in breast cancer survivors or patients not preferring to take hormones because of concern for breast cancer.
  • To assess feasibility and obtain initial estimates of efficacy of three different programs of paced breathing on mood states, fatigue, sleep quality, and blood pressure measurement in breast cancer survivors or patients not preferring to take hormones because of concern for breast cancer.

OUTLINE: Patients are stratified by age (18-49 vs ≥ 50), frequency of hot flashes per day (< 4 vs 4-9 vs ≥ 10), and current tamoxifen, raloxifene, or aromatase inhibitor treatment (yes vs no). Patients are randomized to 1 of 3 treatment arms.

  • Arm I: Patients practice paced breathing for 15 minutes once daily, 6 breaths/min, 5-7 days weekly, following an instructional compact disc (CD), for 8 weeks.
  • Arm II: Patients practice paced breathing for 15 minutes twice daily, 6 breaths/min, 5-7 days weekly, following an instructional CD, for 8 weeks.
  • Arm III: Patients practice paced breathing for 10 minutes once daily, 14 breaths /min, 5-7 days weekly, following an instructional CD, for 8 weeks.

All patients complete daily hot flash diaries, keep a blood pressure log, and complete the following questionnaires: Symptom Experience Diary, Profile of Mood States, Brief Fatigue Inventory, and Pittsburgh Sleep Quality Index.
