Brief summary
The goal of this clinical trial is to learn if treating the lymphatics in head and neck cancer survivors before clinical diagnosis of lymphedema will prevent its development or progression. The main questions it aims to answer are: * Does early lymphatic treatment, before onset of clinical symptoms, prevent the development of head and neck lymphedema? * Does dermal lymphatic backflow provide an early indication of lymphedema and its response to treatment? Over the course of one year, participants will undergo several sessions near-infrared fluorescence lymphatic imaging to assess whether they have abnormal dermal lymphatic backflow following head and neck cancer treatment. Subjects will be divided into two groups, a treated and a control group. The treated group will be asked to complete daily sessions of pneumatic compression therapy at home, while the control group will receive standard-of-card treatment after clinical diagnosis of lymphedema. Researchers will compare the incidence of lymphedema between the two groups to see if treatment before diagnosis prevents the development and progression of head and neck lymphedema.
Interventions
COMBINATION_PRODUCTNear-infrared fluorescence lymphatic imaging
All subjects will undergo lymphatic imaging at enrollment, 3, 6, and 12 months to assess the extent of dermal lymphatic backflow. Small amounts (0.1 mL) of a solution of indocyanine green (ICG) will be intradermally injected near the ear and along the jaw. Images of the lymphatics will be acquired by shining a dim light on the face and neck and acquiring the resulting fluorescent signal emanating from ICG-laden lymph. Images will be processed to calculate the area of the head and neck that show abnormal dermal lymphatic backflow.
DEVICEadvanced pneumatic compression therapy
The advanced pneumatic compression device (APCD) mimics manual lymphatic drainage, a light massage that stimulates lymphatic uptake and function and frequently prescribed for lymphedema therapy.
