Objectives: To determine 1-year and 5-year total healthcare costs and healthcare resource (HRU) associated with renal cell carcinoma (RCC) in older Americans, from a healthcare sector perspective.Materials and Methods: This was a longitudinal, retrospective cohort study using the Surveillance, Epidemiology and End Results-Medicare linked data (2006-2014), which included older (≥66 years) patients with primary RCC and 1:5 matched noncancer controls. Patients/controls were followed from diagnosis (pseudo-diagnosis for controls) until death or up to loss-to-follow-up (censored). Per-patient average 1-year and 5-year cumulative total and incremental total healthcare costs and HRU were reported.Results: A total of 11,228 RCC patients were matched to 56,140 controls. Per-patient cumulative average 1-year (incremental = $38,291 [$36,417-$40,165]; $57,588 vs. $19,297) and 5-year (incremental = $68,004 [$55,123-$80,885]; $183,550 vs. $115,547) total costs (excluding prescription drug costs) were 3 and 1.6 times higher for RCC vs. controls. These estimates were 3.6 and 1.7 times higher for RCC vs. controls when prescription costs were included in total costs. Prescription drug costs accounted for 8.4% (incremental = $3,715) and 18.1% (incremental = $15,375) of the 1-year and 5-year incremental total costs, respectively. RCC patients had greater cumulative number of hospitalizations, emergency department visits and prescriptions in 1- and 5-years, compared to controls.Conclusions: Average first year total cost for a patient with incident diagnosis of RCC is substantially higher than that for controls and it varies depending on the stage at diagnosis. Study findings could help in planning future resource allocation and in determining research and unmet needs in this patient population. [ABSTRACT FROM AUTHOR]

Objective: This study examined the economic burden of renal cell carcinoma (RCC) among older adults. The study also examined healthcare costs by types of resources used and stage at which RCC was diagnosed.Methods: The study analyzed the Surveillance Epidemiology and End Result-Medicare linked data. We included a prevalent cohort of RCC patients from 2013, diagnosed and continuously enrolled in Medicare from 2005 to 2013. RCC patients were matched to controls selected from a 5% sample of noncancer beneficiaries using propensity score matching to calculate incremental costs. Total healthcare costs (THC) were calculated using a phase-based approach, which classified patients into early, continuing, and late phases of care. Costs were also examined by types of resources used and stage at which RCC was diagnosed. Generalized linear models estimated annual incremental costs per patient. The number of older RCC patients was calculated using SEER-Stat and ProjPrev software. The average incremental THC was multiplied by the estimated number of RCC patients to calculate the total economic burden of RCC among older adults.Results: The study included 10,392 each of RCC and control patients. The average annual THC associated with RCC was $7,419 for all phases, $22,752 for the initial phase, $4,860 for the continuing phase, and $13,232 for the late phase of care. The average THC was $4,584 for patients diagnosed at stage I, $4,727 for stage II, $9,331 for stage III, and $31,637 for stage IV. For patients diagnosed at stages I to III, hospital cost (approximately $1,500-$3,400) was the largest component of THC. For stage IV patients, prescription drug cost ($11,747) was the largest component of THC. The projected number of older RCC patients in 2015 was 204,256. The annual economic burden of RCC after weighting for proportion of patients diagnosed at various stages was estimated to be $2.1 billion.Conclusions: RCC was associated with a significant economic burden on Medicare. Healthcare costs associated with RCC varied substantially between early stage and metastatic patients. This research provided a baseline that can be used to assess the economic value of emerging therapies among older RCC patients. [ABSTRACT FROM AUTHOR]
