Interventions for head and neck cancer survivors: A systematic review.

e24042 Background: Quality survivorship care includes cancer-related and general health care domains, including cancer surveillance and prevention of new cancers, management of psychosocial and physical late effects, health promotion/disease prevention, and management of chronic conditions. Survivors of head and neck cancer (HNC) have particularly complex unmet needs across all of these domains. We systematically reviewed interventions for HNC survivors to identify existing evidence and gaps in HNC survivorship care research. Methods: We performed a systemic review (PROSPERO ID: CRD42021269566) using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. We searched MEDLINE, Embase, Emcare and PsycINFO for primary studies published in English between 2000 and 2021 to identify prospective studies for which interventions began after completion of cancer treatment and had a study endpoint ≥1 year after treatment completion. The population included adults treated with for HNC We used Covidence systematic review software to facilitate article screening and study selection. Two reviewers independently screened titles and abstracts followed by full texts for eligibility. Disagreements were resolved by consensus. Two reviewers critically appraised each selected study. Reviewers evaluated risk of bias with the Cochrane RoB 2.0 tool for randomized trials and the ROBINS-I tool for non-randomized studies. Due to the anticipated heterogeneity of included studies, narrative synthesis was used to summarize data. Results: The literature search identified 7395 studies; after applying inclusion and exclusion criteria, 28 studies were identified for critical appraisal: 13 randomized trials and 15 non-randomized studies. Most study interventions (n = 25) focused on surveillance and management of physical effects, including 13 studies that also targeted management of psychosocial effects. Four studies targeted the prevention and surveillance for recurrence and new cancers, and only one study addressed health promotion and disease prevention. Among the 13 randomized studies, 12 had a medium to high risk of bias, and 1 with a low risk of bias. The 15 non-randomized studies included 12 with a high risk and 3 with a medium risk of bias. Common sources of bias included lack of pre-planned sample size and power, lack of blinding of patients or assessors, heterogeneity in population, and attrition with incomplete follow-up. Conclusions: This systematic review and critical appraisal identified gaps in HNC survivorship intervention research targeting under-represented domains of the survivorship framework, and common challenges in study design that introduce risk of bias. To promote quality survivorship care for HNC survivors, scientifically rigorous intervention studies must address broader areas of focus.
