title: Population-Based Cost-Minimization Analysis of CAPOX Versus Modified FOLFOX6 in the Adjuvant Treatment of Stage III Colon Cancer.
abstract: BACKGROUND
  Evidence suggests that CAPOX (capecitabine and oxaliplatin) has efficacy similar to 5-fluorouracil and oxaliplatin (mFOLFOX6) in the adjuvant treatment of colon cancer. CAPOX is partly administered orally and associated with a 3-week rather than a 2-week treatment cycle. A population-based cost-minimization analysis was conducted from the health care payer and societal perspectives to evaluate the potential cost savings of replacing mFOLFOX6 with CAPOX.
  
  
  METHODS
  We applied treatment and toxicity data from phase III trials of CAPOX and FOLFOX-based regimens to the adjuvant colon cancer population in British Columbia, Canada. In this cost-minimization analysis we compared the total costs associated with chemotherapy medications, drug administration and delivery, hospital and clinic visits, treatment-related toxicities, and central venous access devices. Costs to patients in terms of lost time and travel were also considered. It was assumed that patients would receive either 8 cycles of CAPOX or 12 cycles of mFOLFOX6.
  
  
  RESULTS
  From the payer perspective, the use of CAPOX resulted in cost savings of $5339 CAD per patient compared with the use of mFOLFOX6. From a societal perspective, CAPOX was also associated with savings of $6080 CAD per patient. The greatest cost savings with CAPOX were attributed to fewer visits for chemotherapy treatment and decreased central venous access device usage. CAPOX was also associated with reduced loss of time and decreased travel for patients because of the requirement of fewer clinic visits.
  
  
  CONCLUSIONS
  Replacement of mFOLFOX6 with CAPOX in the adjuvant treatment of colon cancer might be associated with potential cost savings from the payer and societal perspectives.
