The goal of this work is to apply novel, noninvasive magnetic resonance imaging (MRI) methods for visualizing lymphatic circulation dysfunction to test a fundamental hypothesis about secondary lymphedema conservative decongestive therapy. Breast cancer treatment-related lymphedema (BCRL) arises secondary to surgical axillary lymph node (LN) dissection and irritation, and is a chronic and lifelong condition affecting a high 21.4% of patients receiving common breast cancer therapies. Persons with secondary lymphedema following axillary lymph node removal also include undergoing treatment for other cancers, such as melanoma involving the upper body, necessitating the need for axially lymph node removal.~Improving lymphedema management represents a major clinical need, and emerging efforts focus on improving quality of life through optimizing post-surgical complex decongestive therapy (CDT), and exploring novel pharmacological and surgical procedures. Here, the investigators will perform a repeated-measures cross-over trial to test the hypothesis that mobilization of protein enriched hardened tissue using graded negative pressure therapy in conjunction with complete decongestive therapy (CDT) is more effective to standard CDT alone for secondary lymphedema management. Both of these conservative physical therapy treatments are commonly employed for treatment of secondary lymphedema.
Persons with secondary arm and/or upper quadrant lymphedema following cancer therapies commonly are prescribed complete decongestive therapy as a course of management of their lymphedema. The investigators will perform a repeated-measures cross-over trial to test the hypothesis that mobilization of protein enriched hardened tissue using graded negative pressure therapy in conjunction with complete decongestive therapy (CDT) is more effective to standard CDT alone for secondary lymphedema management.
