General Information 
There were nearly 62,000 new head and neck cancer (HNC) cases last year accounting for 3% of all 
cancers in the US (1) with an increasing incidence among younger adults due to the human 
papillomavirus (HPV) infection.  Treatment is typically surgical resection of primary lesions and 
extensive lymph node (LN) dissection, followed by fractionated radiation therapy (RT).  Because 
the neck and cervical region contains 1/3 of the body’s LNs (2) surgical disruption of the lymphatic 
vasculature and LNs together with subsequent RT of the head and neck region results in the 
debilitating condition of lymphedema and extensive fibrosis in an estimated 75% of all HNC 
survivors (3, 4). Although the cure rate of these patients is high with extensive LN dissection and 
RT, the debilitating effects of this treatment significantly reduces the quality of survivorship. HNC 
lymphedema can have a profound effect on the range of motion, swallowing, and evening 
breathing.   
Unlike breast cancer where a 10% increase in arm volume is used for diagnosis of lymphedema, 
there is no accepted objective measurement to base the diagnosis of HNC lymphedema.  Weight 
loss and extensive surgery can mask the early signs of edema and lymphedema. As a result, HNC 
patients/survivors are not screened for lymphedema and early treatment of manual lymphatic 
drainage to move accumulated tissue fluid and prevent irreversible tissue changes is typically not 
offered to HNC cancer survivors.

Objectives 
The primary objective of the pilot study is to use NIRF imaging to assess whether pneumatic 
compression can move lymph in HN cancer patients and survivors.  The secondary objectives are 
to assess whether compliant use over a two week period can reverse or reduce the dermal 
backflow that is associated with HN lymphedema and to collect patient feedback on the ease of 
use and perception of symptom alleviation with the Flexitouch System and associated head and 
neck garments after two weeks of daily home use. 
The Flexitouch System and associated garments for extremities and trunk are approved for use by 
patients who are under medical supervision for the treatment of 1) lymphedema (primary or 
secondary); 2) edema resulting from mastectomies, trauma, sports injuries or post immobilization; 
3) venous insufficiencies; 4) wounds and 5) stasis dermatitis, venous stasis ulcers, arterial leg 
ulcers and diabetic leg ulcers.  The variety of garments and accessories available with the 
Flexitouch system are designed to provide targeted compression therapy to different areas of the 
body. Tactile MedicalTM secured FDA clearance via the 510(k) program to market their newly 
designed head and vest garments and Flexitouch Treatment Program H1 (Appendix A, p14). When 
the head garment and vest garment are used together, the resulting compression directs fluid 
from the head to the axilla in one continuous motion, presumably moving fluid from the head and 
neck region into the axilla for uptake into the regional lymphatic. 
We will assess whether the Flexitouch System can move lymph from the region by using NIRF 
imaging before and after treatment with the Flexitouch system, as well as, after 2 weeks of 
compliant home use.  We will assess whether Flexitouch usage is associated with alleviation of 
lymphedema symptoms.

Study Design 
A non-randomized, non-blinded, single site pilot study designed to assess whether NIRF imaging 
can report on the efficacy of the Flexitouch System used to move lymph in HNC survivors.   
Specifically, we will assess whether the Flexitouch System can move lymph from the region by 
using NIRF imaging before and after treatment with the Flexitouch system, as well as, after 2 
weeks of compliant home use.  Participation will require approximately 24 hours over 2 weeks.  
Enrollment is targeted to be completed within 3 months.

The Flexitouch System, when used for upper and lower extremity lymphedema is a standard-of-
care PCD treatment device used routinely in the clinic and for at-home use.  In this study, we seek 
to deploy NIRF imaging to assess the efficacy of the Flexitouch system for moving lymph in HNC 
survivors and to assess whether this correlates with symptom alleviation.

Flexitouch® Advance Pneumatic Compression System
Participants enrolled in the sub-study are not expected to be at any higher or additional 
risk than those who use non-study pneumatic compression devices (PCD), or static 
compression garments approved for use in head and neck region since pressures do not 
exceed the pressures of static compression garments. There is risk associated with using 
any PCD.  These risks include, but are not limited to, risk of explosion if the device is used in 
the presence of flammable gases, risk of electrical shock if the device is immersed in water, 
or it the housing is broken and subject attempts to service the unit.

Potential Benefits
While there is no guarantee of a direct benefit to participants, there is a possible benefit of 
improved lymphatic function and decreased edema with use of the Flexitouch system.

Sample Size/Data Analysis/Subject Withdrawal and Replacement
In this pilot sub-study of a total of ten patients who complete both study visits, we will assess 
whether there are any changes to lymphatic function after a single use of the pneumatic 
compression device and after a two week period of daily home use.   Five patients will undergo 
daily ICD of approximately 32 minutes while another five patients will undergo daily ICD of 
approximately 60 minutes in order to assess the effect of duration on response to therapy.  If, 
after the initial consent and imaging session are completed, a subject withdraws, opts not to 
complete the daily home therapy (<75% of total treatments), OR does not properly use the device 
as instructed, they may be dropped from the study cohort and a replacement subject may be 
enrolled to ensure a full cohort of 10 subjects completes the study.
 
 
 
 
 
 
 
 
  
  
Because this is a pilot study, we cannot statistically power the study for conclusions.  Instead we 
will assess results to visualize trends for a subsequent properly powered study to statistically test 
the hypothesis that the Flexitouch system can restore lymphatic function.

Study Procedures 
The sub-study consists of two NIRF lymphatic imaging sessions (see Section below for NIRF 
procedure) separated by approximately two (2) weeks. At each session, measurements of the 
subject’s head and neck will be recorded and 3D images and/or digital photographs will be taken 
before and after treatment. Participants will don the head and neck and vest garments before 
undergoing Treatment Program H1 with the Flexitouch System.  Imaging with NIRFLI system will

occur before, during and after treatment with the Flexitouch System. The first NIRF lymphatic 
imaging session will establish the presence of lymphatic dysfunction as visualized with the NIRFLI 
System.  The subject will be loaned the Flexitouch® Advanced Pneumatic Compression system 
along with the Head Garment and Vest for Head & Neck.  The subjects will be instructed in the 
proper fitting of the garments and the use of the Flexitouch system.  The subjects will complete 
the Flexitouch Treatment Program H1 (~30-40 minutes or ~60 minutes) daily for approximately 
two (2) weeks. Participants will be asked to keep a diary of their daily use on the Flexitouch 
System.  After approximately two (2) weeks of daily use, the subject will return for the second and 
final NIRF lymphatic imaging session, at which time they will return the Flexitouch System and 
associated garments to the research team.  Subjects will then be asked a series of questions 
related to the ease of use of the Flexitouch System and their perception of the treatment they 
received while using the Flexitouch System.

Data and Safety Monitoring 
The Principal Investigator will be responsible for the monitoring of study data and subject safety.  
Due to the small number of research subjects, the most comprehensive and effective method of 
monitoring will be an individual case review by the PI (Eva M. Sevick-Muraca, PhD) and  clinical 
investigators (Ron J. Karni, MD; Erik A. Maus, MD; and physician designates). As this has always 
been the policy of the PI, the researchers and study team are under specific instructions to make 
the PI aware of all adverse events, expected or unexpected; therefore, the responsibility for 
reporting adverse events is shared with the PI and the research team.
Case Report Forms (CRFs) containing all monitoring information will be completed by the PI, 
clinical investigator(s) or designee and reviewed by the PI and clinical investigator(s).  Case report 
forms (CRFs) will be kept in a locked office or archive.

Statistics 
In this pilot sub-study we will assess whether there are any changes to lymphatic function after a 
single use of the pneumatic compression device and after a two week period of compliant use.  
 
 
 
 
 
 
 
  Specifically, we seek to determine the change in the percentage of area that 
is demarked by dermal backflow in response to the Flexitouch System use after a single session 
and after two seeks of compliant use.  
  
Because this is a pilot study, we cannot statistically power the study for conclusions.  Instead we 
will assess results to visualize trends for a subsequent properly powered study to statistically test 
the hypothesis that the Flexitouch system can reduce dermal backflow and restore lymphatic 
function.  
10.0 Ethics
This sub-study will be submitted to the local IRB, the Committee for the Protection of Human 
Subjects (CPHS), for approval to begin research and study oversight.  
Informed consent will be conducted by a member of the research team.  When possible, a copy of 
the consent will be provided to the study candidate prior to the clinic visit.  At the first clinic visit, 
a private room will be used to review the consent with the candidate and to answer any questions 
or concerns they may have regarding participation in the research study.
