摘要
Background: Over the past 20 years, the mechanisms of action, duration of benefits and economic costs of newly licenced cancer drugs have changed significantly; however, summary data on these characteristics are limited. Methods: In this study, using historical copies of the British National Formulary and relevant contemporary publications, we have documented for each new cancer drug the year of introduction, therapeutic classification, initial indication, median duration of treatment and the cost of treatment at introduction relative to the then current UK GDP per capita. Results: Before 2000, there were 69 cancer treatment drugs available, of which 50 (72.5%) were classical cytotoxic drugs. In the subsequent 15 years, there have been 63 more new cancer treatment drugs added, including 20 kinase inhibitors and 11 monoclonal antibodies. The average median duration of treatment with a new drug has risen from 181 days in 1995-1999 to 263 days in 2010-2014. The average cost of treatment has also risen from 3036.91 pound (20.6% of UK per capita GDP) in 1995-1999 to 20 pound 233 (89.0%) in 2005-2009 and now to 35 pound 383 (141.7%) in 2010-2014. Conclusions: The last 5 years has seen 33 new cancer drugs. These drugs deliver significant benefits in patient outcomes and are taken for increasing lengths of time. Alongside these clinical benefits, the direct costs of new treatments have increased significantly over the past decade.
