title: Assessment and measurement of head and neck lymphedema: state-of-the-science and future directions.
abstract: Currently, assessment and measurement of lymphedema in head and neck cancer patients is difficult. The aims of this report are to examine the current state of science regarding available measurement of head and neck lymphedema, to identify gaps in clinical evaluation of head and neck lymphedema, and to propose future research directions for advancing the assessment of head and neck lymphedema. The authors conducted a comprehensive literature review based on PubMed, CINAHL, Cochrane database, EMBASE, and PsycINFO from 1989 to 2014. Primary search terms included head and/or neck cancer, head and/or neck and/or face, lymphedema, edema, swelling, fibrosis, measurement, assessment, and evaluation. The authors also reviewed information from the Oncology Nursing Society, National Lymphedema Network, National Cancer Institute, American Cancer Society, and other related healthcare professional association web sites. Based on the nature/characteristics of measurement reported in the literature, methods for assessment of head and neck lymphedema can be categorized into: (1) patient-reported outcome (PRO) measures (e.g., symptom tool), (2) clinician-reported outcome (CRO) measures based on clinical grading criteria via a clinical exam (external lymphedema evaluation by physical examination and internal edema examination via endoscopy), and (3) technical capacity/measurement techniques (e.g., imaging techniques). Although a number of measures have been reported in the literature, clinically useful PRO and CRO measures, and reliable and sensitive measurement techniques need to be validated to address gaps in assessment of head and neck lymphedema, and to be easily used in early identification of lymphedema and assessment of treatment/interventional effects.
