Refinement and Validation of the Head and Neck Lymphedema and Fibrosis Symptom Inventory.

ABSTRACT:

Purpose

Lymphedema and fibrosis (LEF) are common yet overlooked late effects of head and neck cancer and its therapy. Lack of reliable and valid measures of head and neck LEF is a critical barrier to the timely identification and management of head and neck LEF. To fill this gap, we developed and pilot tested a 64-item patient-reported outcome measure ( Lymphedema Symptom Intensity and Distress Survey-Head and Neck, LSIDS-H&N). This article aims to report the process of further validation and refinement of the tool.

Methods and materials

A prospective, longitudinal study was conducted, and 120 patients with oral cavity and oropharyngeal cancer were recruited. Participants completed the LSIDS-H&N at pretreatment, end of treatment, and every 3 months up to 12 months after treatment. SAS PROC VARCLUS was used to generate preliminary clusters of item responses. Internal consistency of the item responses within each cluster was assessed using Cronbach's alpha.

Results

A total of 117 patients completed the study. The participants reported that the LSIDS-H&N was easy to understand and captured their symptoms and medical conditions. However, >50% of participants indicated that the survey was burdensome due to length. Thus, we proceeded with item reduction, and the shortened tool (33-item) was named Head and Neck Lymphedema and Fibrosis Symptom Inventory (HN-LEF Symptom Inventory). The subsequent exploration of symptom clusters identified 7 symptom domain clusters (eg, soft tissue and neurologic toxicity), all of which demonstrated good internal consistency.

Conclusions

The HN-LEF Symptom Inventory has been carefully developed and refined to allow clinicians and researchers to capture LEF-associated symptom burden and function impairments. Additional rigorous psychometric testing of the tool is ongoing to further validate the strength and internal validity of this tool.

Project description:BACKGROUND:Head and neck cancer (HNC) patients are at high risk for developing lymphedema and fibrosis (LEF) following cancer treatment. Once HNC patients develop LEF, they need to conduct life-long self-care to slow LEF progression and reduce associated symptom burden and functional deficits. Data demonstrate that inadequate LEF self-care may be a potentially remediable issue. The objective of this study is to explore the feasibility and preliminary efficacy of an Information-Motivation-Behavioral (IMB) Skills model-driven self-care program (SCP) to improve LEF management and reduce LEF-related symptom burden and functional impairments. METHODS/DESIGN:This is a three-arm, prospective, randomized controlled clinical trial to compare: Group 1 - Usual Care, Group 2 - Usual Care Plus LEF-SCP, and Group 3 - Usual Care Plus LEF-SCP Plus Follow-Up. Participants will be HNC survivors aged > 18 years of age, who meet predefined inclusion and exclusion criteria. A sample size of 75 participants is targeted. Interventions will be provided by trained staff. The study assessments for all groups will take place at five points: study entry then 3, 6, 9, and 12 months post enrollment. Outcome measures include: (1) feasibility (barriers to implementation, safety, and satisfaction) of the proposed intervention; (2) self-efficacy and adherence to self-care; and (3) preliminary efficacy (LEF progression, symptom burden, and functional status) of the proposed intervention. DISCUSSION:This will be the first study to evaluate the feasibility of a LEF-SCP in the HNC population and its impact on self-efficacy and adherence. Furthermore, it will evaluate the potential benefit of routine follow-up on adherence and fidelity to the self-care protocol. We expect that the trial will provide evidence supporting the feasibility of a LEF self-care program. In addition, we anticipate that preliminary data will support improved outcomes including increased adherence and fidelity, and decreased LEF-associated symptoms.

Project description:PurposeHead and neck lymphedema (HNL) following radiation therapy for head and neck cancer (HNC) causes patient morbidity. Predicting individual patients' risk of HNL after treatment is challenging. We aimed to identify the demographic, disease-related, and treatment-related factors associated with external and internal HNL following treatment of HNC with definitive or adjuvant radiation therapy.Methods and materialsRelevant clinical, pathologic, and dosimetric data for 76 consecutive patients who received definitive or adjuvant radiation ± chemotherapy were retrospectively collected from a single institution. Multivariable models predictive of external and internal lymphedema using clinicopathologic variables alone and in combination with dosimetric variables were constructed and optimized using competing risk regression.ResultsAfter median follow-up of 550 days, the incidence of external and internal HNL at 360 days was 70% and 34%, respectively. When evaluating clinical and treatment-related factors alone, number of lymph nodes removed and advanced adenopathy status were predictive of external lymphedema. With incorporation of dosimetric variables, the optimized model included the percentage volume of the contralateral lymph node level VII receiving 30Gy V30 ≥50%, number of lymph nodes removed, and advanced adenopathy status. For internal lymphedema, our clinicopathologic model identified both adjuvant radiation, as opposed to definitive radiation, and advanced adenopathy status. With inclusion of a dosimetric variable, the optimized model included larynx V45 ≥50% and advanced adenopathy.ConclusionsHNL following HNC treatment is common. For both external and internal lymphedema, nodal disease burden at diagnosis predicts increased risk. For external lymphedema, increasing extent of lymph node dissection prior to adjuvant therapy increases risk. The contralateral level VII lymph node region is also predictive of external lymphedema when radiation dose to V30 is ≥50%, meriting investigation. For internal lymphedema, we confirm that increasing radiation dose to the larynx is the most significant dosimetric predictor of mucosal edema when larynx V45 is ≥50%.
