e11072 Background: Lapatinib is an oral dual tyrosin kinase inhibitor of EGFR and HER2 and compared to trastuzumab penetrates to CNS. We evaluated efficacy and safety of lapatinib treatment according to different metastatic sites involvement using data from IntERB registry that has been initiated and run by Czech Society for Oncology and Institute of Biostatistics and Analyses at Masaryk University, Brno, Czech Republic. Methods: An analysis included 213 patients with HER2 positive metastatic breast cancer treated from January 2007 to September 2011. Lapatinib was mostly administered orally 1250mg/day with capecitabine (2000mg/m2 D1-14), 16 patients received lapatinib in monotherapy. All patients had experienced progression during prior trastuzumab based therapy. Results: Median age was 56 years (range 23 – 78). Median duration of lapatinib therapy was 20.6 weeks (range 1–146). Complete response was achieved in 13 patients (6.1%), partial response in 31 (14.6%), stable disease in 118 (55.4%). In 26 disease have progressed (12.2%); response could not be assessed in 25 patients (11.7%). PFS for whole group was 7.1 months (95% CI 5.9-8.5). Overall survival was 17.2m (95% CI 15.8-18.6), probability of 6m OS was 80.3% and 1-year OS was 64%. Metastatic sites specific survival was evaluated in 103 patients. CNS dissemination was initially diagnosed in 31 patients (30.1%), PFS in this group was 6.2m (95% CI 3.3-9.1), OS was not reached, 6-m OS was 67.3%. In non-CNS group (skeletal metastasis in 49.5%, lung 38.8%, hepatic 36.9%, lymphatic 17.5%, other 15.5%) was PFS 6.3m (95% CI 1.6-11.1), OS 22.0m (95% CI 15.3-28.8) and 6-m OS was 88.2%. Most common toxicities were diarrhea in 11.7% patients, rash/skin toxicity in 10.8%, nausea/vomitus in 5.2% and hepatotoxicity in 2.3%. No cardiac toxicity was reported. Therapy was discontinued due toxicity in 9.0%. Conclusions: Lapatinib in combination with capecitabine proved its efficacy in trastuzumab pretreated HER2 positive metastatic breast cancer. Even in patients with CNS involvement was achieved a notable PFS and OS, comparable to non-CNS group of patients. Therapy was well tolerated.

The efficacy and safety of the combination of endocrine therapy (ET) and CDK4/6 inhibitors for patients with hormone receptor (HR)-positive HER2-negative metastatic breast cancer (BC) presenting with visceral crisis or life-threatening conditions represent a challenge for daily clinical practice. Indeed, the peculiarity of this clinical presentation (signs and symptoms of rapidly progressive disease) does not allow to include such patients in a trial aiming for drug approval. On the basis of the scientific evidence available so far, chemotherapy represents the standard of care according to guidelines, on the basis of the more rapid activity in comparison with ET alone. Besides, the combination of ET and CDK4/6 inhibitors have demonstrated in clinical trials to have clinically impactful activity in a short time, thus suggesting a potential role in advanced tumors that require rapid response. Herein, we report the clinical history of a young woman with HR-positive HER2-negative metastatic BC and a pancytopenia due to carcinomatosis of the bone marrow receiving letrozole and leuprorelin plus the CDK4/6 inhibitor palbociclib, who significantly derived clinical benefit from treatment. Considering that these peculiar cases are excluded from clinical trials, the estimation of the magnitude of the benefit of the newer ET combination may potentially represent a practical question for large case series and real-world studies.
