Costs were estimated from the perspective of the National Health Service in the <jats:styled-content style="fixed-case">UK</jats:styled-content> and included expenditures for trial treatments, concomitant medications, and use of related hospital and primary care services. Quality‐adjusted life‐years (<jats:styled-content style="fixed-case">QALY</jats:styled-content>s) were calculated according to patients' responses to the generic EuroQol <jats:styled-content style="fixed-case">EQ</jats:styled-content>‐5D‐3L instrument, which evaluates health status. Results are expressed as incremental cost‐effectiveness ratios (<jats:styled-content style="fixed-case">ICER</jats:styled-content>s) and cost‐effectiveness acceptability curves.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>The per‐patient cost for <jats:styled-content style="fixed-case">ZA</jats:styled-content> was £12 667, £251 higher than the equivalent cost in the no <jats:styled-content style="fixed-case">ZA</jats:styled-content> group. Patients in the <jats:styled-content style="fixed-case">ZA</jats:styled-content> group had on average 0.03 <jats:styled-content style="fixed-case">QALY</jats:styled-content>s more than their counterparts in no <jats:styled-content style="fixed-case">ZA</jats:styled-content> group. The <jats:styled-content style="fixed-case">ICER</jats:styled-content> for this comparison was £8 005. Sr89 was associated with a cost of £13 230, £1365 higher than no Sr89, and a gain of 0.08 <jats:styled-content style="fixed-case">QALY</jats:styled-content>s compared to no Sr89. The <jats:styled-content style="fixed-case">ICER</jats:styled-content> for Sr89 was £16 884. The probabilities of <jats:styled-content style="fixed-case">ZA</jats:styled-content> and Sr89 being cost‐effective were 0.64 and 0.60, respectively.</jats:p></jats:sec><jats:sec><jats:title>Conclusions</jats:title><jats:p>The addition of bone‐targeting treatments to standard chemotherapy led to a small improvement in <jats:styled-content style="fixed-case">QALY</jats:styled-content>s for a modest increase in cost (or cost‐savings). <jats:styled-content style="fixed-case">ZA</jats:styled-content> and Sr89 resulted in <jats:styled-content style="fixed-case">ICER</jats:styled-content>s below conventional willingness‐to‐pay per <jats:styled-content style="fixed-case">QALY</jats:styled-content> thresholds, suggesting that their addition to chemotherapy may represent a cost‐effective use of resources.</jats:p></jats:sec>
