Background
Delays in treatment of head and neck squamous cell carcinoma (HNSCC) are known to increase disease recurrence, generating the need for additional salvage treatment, often with immunotherapy.
Methods
Three treatment metrics were identified: time from diagnosis to treatment initiation (TTI), time from surgery to postoperative radiotherapy (surg → PORT), and total treatment package time (TPT). Financial toxicity was calculated using hazard ratios, pembrolizumab cost, and dosing data for a Veterans Health Administration (VHA) institutional cohort (n = 338) and a standardized cohort (n = 100).
Results
Estimated financial toxicity for the VHA cohort was $2 047 407, $316 545, and $1 114 101 for TTI, surg → PORT, and TPT, respectively. Estimated financial toxicity for the standardized patient cohort was $454 028, $544 576, and $1 879 628 for TTI, surg → PORT, and TPT, respectively.
Conclusions
Failure to meet established HNSCC treatment metrics generates significant, yet avoidable, institutional financial toxicity which is particularly relevant to integrated single‐payer systems such as the VHA in the modern immunotherapy era.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
