Abstract

Aim

Brain metastases (BM) are a common clinical problem in patients with HER2-positive metastatic breast cancer. The retrospective study was designed to evaluate the efficacy of lapatinib and capecitabine in this group of advanced breast cancer patients.

Methods

Group of 83 patients with HER-2 positive metastatic breast cancer receiving lapatinib and capecitabine between July 2007 and May 2013 was retrospectivelly evaluated. Patients received lapatinib 1250 mg once daily and capecitabine 2000 mg/m(2) daily in two doses, days 1-14, every 21 days. All patients were treated with trastuzumab either in adjuvant or metastatic setting and most of the patients (90%) received prior therapy for metastatic disease. Patients were assessed for median time to progression (mTTP) and toxicity of treatment.

Results

Among 83 patients 19 (23%) had brain metastases. Median time to progression was 35 weeks in patients with BM and 28 weeks in patients without BM (P = 0.028). Among adverse events the most common were hand-foot syndrome (59% of patients) and diarrhoea (42%). All toxicities were well manageable.

Conclusions

Lapatinib plus capecitabine is effective and well tolerated treatment in breast cancer patients with brain metastases.
