Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Devices - 23-32 mmHg compression sleeve with gauntlet

Experimental: BIS Assessment - Patients will undergo measurements by trained staff. Measurements will be performed pre-op and at 3, 6, 12, 15\*, 18, 21\*, 24, and 36 months post-op. Measures include L-Dex, skin assessment and self-report forms. Patients with \< 6.5 L-Dex units change will continue follow-up for 36 months. Patients with an L-Dex value change = 6.5 will undergo circumference measurement and begin treatment for 4 weeks with a 23-32 mmHg compression sleeve with gauntlet. At the end of 4 weeks patients will have their arms measured. Those demonstrating improvement will continue with follow up. Those not demonstrating improvement will be removed from the study and their medical oncologist or surgeon will be notified.

\*At discretion of the site PI or attending physicians.

Active comparator: Tape Measure - Patients will undergo measurements by trained staff. Measurements will be performed pre-op and at 3, 6, 12, 15\*, 18, 21\*, 24, and 36 months post-op. Measures include arm volume (tape measure), skin assessment and self-report forms. Patients with no volume increase will continue follow-up for 36 months. Patients with a volume change of between = 5% and \< 10% in the at-risk limb will undergo L-Dex testing and begin treatment for 4 weeks with a 23-32 mmHg compression sleeve with gauntlet. At the end of 4 weeks patients will have their arms measured. Those demonstrating improvement will continue with follow up. Those not demonstrating improvement will be removed from the study and their medical oncologist or surgeon will be notified.

\*At discretion of the site PI or attending physicians.


Treatment: Devices: 23-32 mmHg compression sleeve with gauntlet
A compression intervention consisting of a sleeve and gauntlet with 23-32mm of tension worn for four weeks that is initiated based on a BIS L-Dex change that is =6.5 units higher than pre-surgical baseline measure, or a tape measurement guided volume change in the affected arm that is between =5% and \<10% above pre-surgical baseline.
