Clinical Trial Summary

This study will be a 4 to 6 week randomized, controlled, assessor blinded, trial comparing a negative pressure massage device (intervention group), to the standard manual lymph drainage massage (control group), in breast cancer patients with chronic upper extremity lymphedema.


Description:

Lymphedema (LE) is a protein-rich interstitial swelling caused by reduced lymph transport secondary to lymphatic system damage from cancer treatments. 1 in 5 women will develop LE following breast cancer treatment. These women have greater restrictions in activity and poorer quality of life (QOL) and are more prone to cellulitis than women without LE. LE is incurable and progressive. Persistent lymph stasis creates a condition of chronic inflammation that contributes to fibrosis and fatty deposition in the subcutis of the affected limb. The fibro-adipose changes associated with chronic LE make it less responsive to treatments that primarily target limb volume. Treatments are needed that can improve these skin and subcutaneous tissues changes, as well as reduce limb volume. This 4 to 6 week randomized controlled pilot feasibility study will enroll 80 women with chronic arm LE, and will evaluate a novel negative pressure massage device that mobilizes skin and subcutaneous tissue. This negative pressure treatment provides vertical (lifting) and horizontal stretching of the skin and underlying fascial structures, which increases the subcutaneous space for lymphatic circulation, improves lymph flow, and has the potential to decrease fibrosis. This treatment will be compared to the standard of care massage: manual lymphatic drainage. Women will be randomly assigned to either the negative pressure massage device (intervention group), to the standard manual lymph drainage massage (control group) Objectives: To evaluate recruitment and retention rates; to determine rates of adverse events; and to determine effect sizes for limb volume, tissue induration; and patient reported outcomes of arm function, QOL, and body image in response to treatment

Study Design


Intervention

Device:
PhysioTouch
The PhysioTouch is a hand-held device that administers negative pressure under the treatment head, and gently pulls the underlying skin and subcutaneous tissue into the suction cup. This suction produces a stretch to the skin and in the subcutaneous tissue space. This action is thought to facilitate lymphatic flow from the interstitium into the lymphatic vessels, and mobilizes the superficial fascia.
Other:
Manual Lymph Drainage (MLD)
MLD is a practitioner-applied manual massage technique designed to decrease limb volume in patients with lymphedema by enhancing movement of lymph fluid, resulting in reductions in interstitial fluid.

Primary Recruitment Rates The recruitment rate is defined as the number of women who were screened and then enrolled on the study divided by the the total number of women screened overall. At 4 weeks
Primary Percentage of Participants Who Completed All Study Visits Retention rates for both arms of this study were evaluated. The numbers of women who completed the study will be recorded. Reasons for drop out will be ascertained. At 4 weeks
Secondary Mean Limb Volume Arm circumferential measurements of both limbs and hands were taken twice, using a spring-loaded tape measure. The hand was measured in two locations. Upper extremity measurements were taken at 10 centimeter (cm) intervals from the ulnar styloid of the wrist up to a total distance of 40 cm. Circumferences were measured using the procedures outlined by Cornish et al. Limb volume was calculated using the formula for volume of a truncated cone and reported in millilitre (ml) At Baseline

Secondary Mean Lymphedema Index (L-DEX®) Ratio Scores Bioimpedance spectroscopy (BIS) measurements were taken using a single channel BIS, tetrapolar device (LDex device, ImpediMed, San Diego, CA) to evaluate upper limb bioelectrical impedance. Impedance ratios (unaffected/affected limb) are calculated and converted to L-Dex ratio score. With development of lymphedema, impedance of extremity decreases and L-Dex ratio therefore increases. An L-Dex ratio score of 10 is equivalent to impedance ratio of 1.139 (which is = to 3 standard deviations (SD) from mean normative BIS data) for at-risk dominant arms & 1.066 for at-risk non-dominant arms, respectively. Each 1 standard unit in L-Dex is equivalent to impedance ratio of 0.03. Using this arbitrary scale relevant to normative standards, a patient is determined to have arm lymphedema if L-Dex ratio score exceeds 7.1, which is 2 SD above mean normative data for BIS impedance ratios. Higher L-Dex ratio score means higher impedance ratio between limbs, which means more volume in affected limb. At Baseline

Secondary Mean Skin Induration Score The SkinFibroMeter (Delfin Technologies, Finland) was used to measure tissue induration. The SkinFibroMeter consists of a 1 mm long indenter and a force sensor. The device is gently pressed against the skin. The indenter imposes a constant deformation when the reference plate is in full contact with the skin. The skin and the underlying superficial subcutis resist the deformation. Measurements will be taken bilaterally at 5 locations: the first dorsal web space; the medial forearm halfway between the ulnar styloid and medial epicondyle; the lateral forearm halfway between the radial styloid and the lateral epicondyle; the medial arm 3 inches proximal to the medial epicondyle; and the lateral arm 3 inches proximal to the lateral epicondyle. Five recordings were taken at each location and a mean score was calculated.The induration value in Newtons (N) is recorded. At Baseline

Secondary Mean Degrees of Shoulder Range of Motion Active shoulder flexion and abduction range of motion (ROM) was assessed, with patients supine, using a goniometer and standardized procedures reported by Norkin and White. Bilateral ROM was assessed. Two measurements will be taken for each motion and a mean obtained, for each, bilaterally. Findings are recorded in degrees. At Baseline

Secondary Mean Grip Score Grip strength was assessed using a Jamar hydraulic hand dynamometer (Patterson Medical, Bolingbrook, IL). Patients will be tested in sitting with the feet flat on the floor, the arm at the side with the elbow flexed to 90 degrees. The patient was instructed to maximally squeeze the handle and hold for a count of 3. The peak-hold needle will automatically record the highest force exerted. Two trials for each extremity will be done and a mean grip score (in kilogram of force) calculated. A higher score indicates a greater grip strength. At Baseline

Secondary Mean Self-Administered Comorbidity Questionnaire (SCQ) Scores The SCQ consists of 13 common medical conditions that are simplified into language that could be understood without any prior medical knowledge. Patients were asked to indicate if they had the condition using a "yes/no" format. If they indicate that they had a condition, they are asked if they received treatment for it (yes/no; proxy for disease severity) and did it limit their activities (yes/no; indication of functional limitations). • For each condition, a patient can receive a maximum of 3 points. Because there are 13 defined medical conditions and 2 optional conditions, the maximum achievable total score is 45 points as all items were available for use. At Baseline

For each site difference, the reported score can range from 1 (very slight difference) to 3 (very noticeable difference). The total score can range from 1 (very slight difference at 1 site) to 9 (very noticeable difference at all 3 sites). Higher scores indicate a greater noticeable difference between the two arms At Baseline

Secondary Mean Disability of Arm, Shoulder, Hand Questionnaire (DASH) Scores The DASH is a 30-item self-report questionnaire measuring upper limb symptoms and ability to perform common functional activities in people with musculoskeletal disorders of the upper limb. The disability/symptom questions are scored 1 thru 5, with 1=being no difficulty and 5=being unable to perform. At least 27 of the 30 items must be completed for a scaled score to be calculated. The assigned values for all completed responses are simply summed and averaged, producing a raw score between 1 and 5. This value is then transformed to a score out of 100 to create a DASH disability/symptom score = [(sum of (n) responses) - 1] x 25, where n is equal to the number of completed responses. Each scaled score cut point is scored as 0 (no disability), 25 (mild disability), 50 (moderate), 75 (severe) and 100 (unable to perform activities). Higher scores indicate greater limitation.
