Home-based Compression Therapy for Arm and Truncal Lymphedema in Breast Cancer

No studies have tested the potential benefit of the Flexitouch® truncal/chest garments on reducing truncal lymphedema in breast cancer survivors (BCS) or the theoretical added benefit of applying truncal/chest pneumatic compression therapy to open lymph channels in individuals who have only limb lymphedema or its impact on the trunk/chest. The purpose of this two-part study is to fill gaps related to: 1) the impact of the Flexitouch® System on truncal lymphedema, and 2) the therapeutic benefit of truncal /chest pneumatic compression therapy for arm lymphedema.

Hypotheses:

Part One: BCS with arm and truncal lymphedema. H1: Arm swelling (as measured by bioelectrical impedance \& arm girth in cm) will be reduced after 10 sessions with the Flexitouch® System.

H2: Truncal swelling (as measured circumferentially) will be reduced after 10 sessions with the Flexitouch® System.

H3: The number, severity, and intensity, of physical and psychological symptoms (as measured by the Lymphedema Symptom Intensity and Distress Scale: Trunk and Arm) will be reduced after 10 sessions with the Flexitouch® System.

H4: Functional assessment scores (as measured by the Functional Assessment Screening Questionnaire \[FASQ\] will improve after 10 sessions with the Flexitouch® System.

Part Two: BCS with Arm Lymphedema H1: Arm volume (as measured by bioelectrical impedance \& arm girth in cm) will be significantly reduced after one month of home use in participants using the Flexitouch® System (truncal, chest, and arm compression) when compared to those using the Flexitouch® System (arm compression only).

H2: Truncal measurements/volume (as measured circumferentially) will be less after one month of home use with the Flexitouch® System (truncal, chest, and arm compression) when compared to those using the Flexitouch® System (arm compression only).

H3: The number, severity, and intensity, of physical and psychological symptoms (as measured by Lymphedema Symptom Intensity and Distress Scale - Arm ) will be significantly reduced after one month of home use with the Flexitouch® System (truncal, chest, and arm garments) when compared to individuals using the Flexitouch® System (arm compression only) .

H4: Functional assessment scores (as measured by the FASQ) will be significantly higher after one month of home use with the Flexitouch® System (truncal, chest, and arm garments) when compared to individuals using the Flexitouch® System (arm compression only).

Screening Procedures This study will have a three-phase screening process.

Phase One:

Participants will be screened either in person or via the telephone.

Phase Two:

If the person being interviewed is eligible and interested, study staff will obtain phone consent for a brief interview to obtain basic medical and treatment information and to share this information with the study doctor, who will write prescriptions for treatment based upon these data. After a prescription is obtained, study staff will contact participants by phone and schedule the on-site visit.

Phase Three:

Participants will come to the Vanderbilt University for measurement of arms and truncal assessment. Phase Three Screening informed consent will be obtained prior to any measurements. These measurements will serve as baseline entry into the study for those who meet criteria.

Baseline Interview All Participants: Once written informed consent is obtained, study staff will interview the participants to obtain demographic and treatment (lymphedema and breast cancer) history. Participants will complete symptom and quality of life forms.

Part One Study:

Dosage and Setting:

Participants will receive a total of 10 treatments, one hour per day for 10 days consecutively. Treatment One will be conducted under study staff supervision at VUSN or other Vanderbilt location. Treatments Two through Ten will be self-administered, at home, as this is an FDA approved at-home self-care device.

Study staff will make an at home visit for Treatment Two in order to observe the application and use of the device and to measure the participant's trunk and arms and examine arm and trunk.

Home Treatment One Observation and Measurement:

Physical Assessment/Measurement:

* Study staff will visually examine the affected and unaffected arms and truncal areas (collarbone to navel and small of back).
* Participants will be asked to sit at their dining table with arms extended to the side at shoulder height at shoulder level. A non-flexible tape will be used to measure girth at the metacarpal shaft of the hand and then, starting at the ulnar styloid, in 10 cm intervals to the shoulder. Each arm will be measured 2 times and the average used.
* Study staff will then measure the trunk twice at five locations.
* During bioimpedance: Study staff will assist the patient onto a bed or sofa and measure arm volume using bioelectrical impedance. Participants will be placed in a supine position with legs not touching one another. An alcohol pad will be used to prep each wrist next to the joint, the dorsal surface of each hand (1 cm proximal to the middle knuckle), and the dorsal surface of one foot (1 cm proximal to the joint of the second toe). These areas will be allowed to dry and lightly adhesive electrodes will be applied. Measurement of affected and unaffected arms will be conducted as directed by the computer software in each impedance device. This measurement will take less than five minutes. The leads and electrodes will then be removed.
* Study staff will weigh the participant twice and record the average.
* At the end of the treatment session, study staff will again measure the arms and trunk of the participant. Using the same procedures.

Treatment Observation:

Staff will observe for:

* Participants going to restroom, removing any compression garments, constrictive clothing/undergarments or foot coverings they are wearing, and to removing any jewelry prior to treatment.
* Participants changing into scrub suits.
* Use of treatment record checklist to set dials
* Participants resting in a supine position during treatment.
* Appropriate placement of garments.
* Pressures will be set at manufacturers recommended levels of compression using program UEO1/U1 and standard pressure (not intense pressure) only.
* Active time on the device approximately 60 minutes.
* Completion of treatment record checklist after treatment.
* Staff will correct any errors noted and educate as needed.
