The National Institute for Health and Clinical Excellence recommends vinorelbine (VNB), paclitaxel, docetaxel, and gemcitabine in the treatment of non-small cell lung cancer. An economic model was prepared to determine the comparative cost of these agents, including the new oral formulation of VNB from a United Kingdom National Health System perspective. Clinical effectiveness was determined from published trials. Costs of drug acquisition, administration, toxicity management, and patient transportation costs were calculated from reference publications. A Markov model was used to estimate the cost per patient over 52 weeks. Intravenous VNB, gemcitabine, paclitaxel, and docetaxel incur annual follow-up costs of 3,746 pounds, 5,332 pounds, 5,977 pounds, and 6,766 pounds, respectively, while oral VNB with outpatient administration on d1, and self-administration at home on d8 every 21 days has a cost per patient per year of 2,888 pounds. Oral VNB allows further hospital resources savings.
