Patients were characterized as FLF (those who restart, switch to any chemotherapy; had a hematopoietic stem cell transplant; or newly initiated radiation therapy [RT] after discontinuing FL) or non-FLF (those not considered as FLF). Direct health care utilization and expenditures were measured over both fixed and variable length follow-up periods and during FL therapy.Results: There were 77 FLF and 602 non-FLF patients who met the final inclusion criteria. FLF and non-FLF patients were demographically similar with mean age 38.5 years and 47.5% females. Average per patient per month (PPPM) costs were significantly higher for FLF patients during all follow-up (US$20,266 vs US$7,772, P<0.05). Annual total expenditures were significantly higher among FLF patients (US$198,388) vs non-FLF patients (US$37,549). FLF (vs non-FLF) patients had a significantly shorter duration of FL therapy (116 vs 131 days, P=0.024) and higher total PPPM expenditures during FL (US$29,040 vs US$16,369, P<0.05). Annual cost varied by failure type with those who failed due to restart incurring the highest cost (US$269,189) and those who switched incurring the lowest cost (US$46,951). FLF patients had a significantly greater utilization in every health care resource category during follow-up.Conclusion: FLF (vs non-FLF) patients utilized substantially more health care resources and incurred a substantially higher economic burden. Over 5 years, FLF patients with at least two lines of treatment were projected to incur US$535,846 of health care costs. Further research is needed to determine optimal treatment that could reduce the risk of progression, need for treatment after FL, and enhance long-term clinical and economic outcomes.
