Pharmaco-economic comparative evaluation of combination chronotherapy vs. standard chemotherapy for colorectal cancer.

Results of recent trials comparing combination chemotherapy consisting of 5-fluorouracil (5-FU), folinic acid (FOL), and oxaliplatin, given either as flat (A) or chronomodulated (B) infusion for metastatic colorectal cancer, were subjected to pharmaco-economic evaluation. The overall cost of treatment with the flat and chronomodulated protocols was equivalent. The expense of the delivery of medications with the chronotherapeutic arm (B) was greater than with the standard arm (A) because it was feasible to administer more courses (requiring more frequent doctor visits) and higher doses (high cost of medications) with containment of toxic reactions. Chrono-arm B was definitively more cost-effective than standard flat-arm A treatment since it made the outcome of treatment more effective; there was greater tumor response rate and longer time to progression with less treatment-associated toxicity. Finally, selection of the Melodie brand infusion pump to deliver the chronotherapy resulted in a further 18% reduction of overall costs and made it possible for patients to enjoy increased autonomy and improved quality of life.
