NCT ID: NCT00902330

Last Updated: 2015-11-23

Results Overview

Using Hospital Anxiety and Depression Scale (HADS) a 14 item scale, 7 relate to anxiety, 7 to depression; each item is scored from 0-3, a person can score 0 to 21 for either anxiety or depression (0 is best and 21 is worst), Brief Pain Inventory (BPI) short-form measures the intensity and interference of pain in the patient's life; 12 questions with 0 (does not interfere) to 10 (completely interferes); mean will be used as the measure of pain; Brief Fatigue Inventory (BFI) assess the severity and impact of cancer-related fatigue. Has 9 questions with 0 (does not interfere) to 10 (completely interferes), the total mean score is the mean of the 9 questions; severe fatigue can be defined as a score of 7 or higher, General Sleep Disturbance Scale (GSDS) 21 items to evaluate sleep issues (0=never to 7=every day); the 21 items are summed to produce a total score of 9=no sleep disturbance to 137=extreme sleep disturbance . Used standard questionnaire

Participant Flow

Women with stage I to IIIA breast cancer scheduled to receive chemotherapy with a performance score \<2 recruited from five Cancer Centers across Virginia. Previous chemotherapy, dementia or active psychosis, seizure disorder, implanted electrical device, or taking medication psychiatric condition with 30 days prior to enrollment were excluded.

Following completion of informed consent study participants were stratified by initial chemotherapy regimen (dose dense versus non-dose dense) and then randomly assigned to one of two groups: actual or sham CES.

Measure
Arm I (Cranial Microcurrent Electrical Stimulation [CES])
Patients receive a CES unit (Alpha-Stim® 100 Microcurrent Stimulator) that passes microcurrent levels of biphasic electrical stimulation via ear-lobe electrodes. The CES unit is preset to provide 1 hour of 100 μA (sub-sensory level), modified square-wave biphasic stimulation on a 50% duty cycle at .05 Hz, and to automatically turn off at the end of 1 hour. Patients use their CES unit once daily in weeks 1-18. energy-based therapy: Given once a day for 18 weeks
Arm II (Sham CES)
Patients receive a CES unit as in arm I, but the ear-lobe electrodes do not pass electrical current. Patients use their CES unit once daily in weeks 1-18. sham intervention: Given once a day for 18 weeks

Timeframe: up to 2 weeks after completion of study treatment, for up to 8 months

Examine correlations between the symptoms at baseline to determine a general pattern of association. Factor analysis (a statistical method used to describe variability among observed, correlated variables in terms of a potentially lower number of unobserved variables called factors) was performed to examine how these 5 symptoms cluster. A principal component factor analysis was performed on the correlation matrix for the symptom scores of anxiety, depression, pain, fatigue and sleep disturbance at up to two weeks after completion of study treatment, up to 8 months). For each analysis two factors were retained that explained 74% of the variability for the baseline symptom scores, 79% of the variability of the symptom scores at the midpoint and 78% of the variability in symptom scores at study completion. A varimax rotation was utilized and the factor loadings from the varimax rotation were reported.

Timeframe: Baseline

Measured using the Functional Assessment of Cancer Therapy for Patients with Breast Cancer (FACT-B). A 44-item self-report instrument designed to measure multidimensional quality of life in patient with breast cancer. 0=not at all to 4=very much. Utilized standard questionnaire scoring system. The items are summed to produce a total score 0=not at all to 176=very much. The FACT-B BCA has 10 questions that range from 0 (not at all) to 4 (very much); thus the FACT-B BCA ranges from 0 to 40. Both the FACT-B and FACT-BCA are scored so that high scores indicate higher levels of quality of life.

Measured using Hospital Anxiety and Depression Scale (HADS) a fourteen item scale, 7 relate to anxiety and 7 to depression; each item is scored from 0-3, this means a person can score 0 to 21 for either anxiety or depression (0 is best and 21 is worst), Brief Pain Inventory (BPI) short-form measures the intensity of pain and interference of pain in the patient's life; 12 questions with 0 (does not interfere) to 10 (completely interferes); mean will be used as the measure of pain; Brief Fatigue Inventory (BFI) assess the severity and impact of cancer-related fatigue. it has 9 questions with 0 (does not interfere) to 10 (completely interferes); severe fatigue can be defined as a score of 7 or higher, General Sleep Disturbance Scale (GSDS) 21 items to evaluate sleep issues (0=never to 7=every day); the 21 items are summed to produce a total score of 9=no sleep disturbance to 137=extreme sleep disturbance .

Measured using the Functional Assessment of Cancer Therapy for Patients with Breast Cancer (FACT-B). A 44-item self-report instrument designed to measure multidimensional quality of life in patient with breast cancer. 0=not at all to 4=very much. Utilized standard questionnaire scoring system. The items are summed to produce a total score 0=not at all to 176=very much. The FACT-B BCA has 10 questions that range from 0 (not at all) to 4 (very much); thus the FACT-B BCA ranges from 0 to 40. Both the FACT-B and FACT-BCA are scored so that high scores indicate higher levels of quality of life.
