In a phase III trial of women with HER2+ metastatic breast cancer (MBC) previously treated with trastuzumab, an anthracycline, and taxanes (EGF100151), lapatinib plus capecitabine (L+C) improved time to progression (TTP) versus capecitabine monotherapy (C-only). In a trial including HER2+ MBC patients who had received at least one prior course of trastuzumab and no more than one prior course of palliative chemotherapy (GBG 26/BIG 03-05), continued trastuzumab plus capecitabine (T+C) also improved TTP. ⋯ When compared against capecitabine alone, the addition of lapatinib has a cost-effectiveness ratio exceeding the threshold normally used by NICE. Compared with T+C, L+C is dominant in the base case and approximately equally likely to be cost-effective in probabilistic sensitivity analyses over a wide range of threshold values.
