EDGE Task Force on Head and Neck Cancer Outcomes A Systematic Review of Outcome Measures for Quantifying External Lymphedema:

Systematic review of head and neck lymphedema assessment

Head and neck lymphedema (HNL) is an increasingly recognized complication of head and neck cancer and its treatment. However, no consensus exists on the "gold-standard" assessment tool for the purposes of diagnosis, classification, or monitoring of HNL. We conducted a systematic review of the literature regarding HNL assessment to determine the optimal method/s of assessment for patients with HNL. A review of publications between January 2000 and September 2021 was undertaken on four electronic databases. Studies were excluded if no clear assessment method of HNL was documented. Sixty-seven articles were included in the study. A wide range of assessment methods for HNL have been reported in the literature. For the purposes of diagnosis and classification of physical findings, computed tomography (CT) appears the most promising tool available for both external and internal HNL. In terms of monitoring, ultrasound appears optimal for external HNL, while a clinician-reported rating scale on laryngoscopy is the gold standard for internal HNL. Patient-reported assessment must be considered alongside objective methods to classify symptom burden and monitor improvement with treatment.

Diagnosis and Treatment of Edema and Lymphedema in the Cancer Patient

BACKGROUND

Lymphedema occurs commonly in cancer survivors. It is crucial to properly assess cancer patients in order to distinguish lymphedema from general edema and to initiate evidence based treatment.

PURPOSE

To provide evidence based recommendations for screening, evaluating, and treating lymphedema and to establish the role of the nurse in the care of patients with lymphedema.

METHODOLOGY

Comprehensive overview with narrative literature review of evidence based lymphedema diagnosis and treatment.

FINDINGS

Cancer-related edema represents numerous complex conditions. A variety of interventions are needed to address prevention, early detection, patient education, and effective treatment.

CONCLUSION

Lymphedema treatment is complex and multimodal, and is provided by an interdisciplinary team of properly trained professionals. Nurses play a major role in evaluating, treating and educating patients on the signs and symptoms of cancer-related edema and patient self-management.

CLINICAL IMPLICATIONS

Evidence-based assessment and treatment should be initiated early to improve outcomes and quality of life in patients with cancer-related lymphedema.
