Measuring financial toxicity in head and neck cancer: a systematic review

Objective: The current study systematically reviews the literature about financial toxicity (FT) in head and neck cancer patients. Three databases were reviewed: PubMed, Scopus and Web of Science. Methods: Full text English papers published from 2000 to 2022 reporting on quantitative results about FT in head and neck cancer survivors collected through structured questionnaires or interviews were included. Results: Twenty-seven articles were included. Most of the articles were published after 2015 and from United States. There was a slight prevalence of papers dealing with oropharyngeal cancer, squamous-cell carcinoma and locally advanced head and neck cancer. Measures of FT were obtained through validated questionnaires like COST, FIT and FDQ. Collected data were mostly referrable to financial spending, financial resources, psychosocial aspect, support seeking, coping care and coping lifestyle subdomain. FT scores by COST were found to be worse in the COVID era. Financial counseling and adequate information about the costs of treatment were two effective strategies to mitigate FT. Conclusions: FT is a relatively new challenge in head and neck cancer treatment, whose expenses are higher than therapies for other cancers. A universal method to assess FT and a unified guideline for the administration of questionnaires are needed to mitigate FT and to improve patient outcomes.
