Self-care for head and neck cancer survivors with lymphedema and fibrosis: study protocol for a randomized controlled trial

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.
