| Abstract | Brain metastases (BM) are frequently diagnosed in metastatic Her2-positive breast cancer. Local treatment remains the standard of care but lapatinib plus capecitabine was recently established as systemic therapy option. Due to a disruption of the blood–brain/tumour-barrier at metastatic sites, even large molecules may penetrate into the central nervous system (CNS). Here, we report on the activity of T-DM1 in Her2-positive breast cancer BM. T-DM1 was administered at a dose of 3.6 mg once every 3 weeks as primary systemic therapy for BM or upon documented CNS progression after initial local treatment. Thus, this study allowed for the appraisal of T-DM1 activity in BM. Restaging was conducted every 12 weeks with MRI or whenever symptoms of disease progression occurred. Ten patients were included; in two asymptomatic subjects, T-DM1 was administered as primary therapy, while eight had progressive BM. All patients had received prior treatment with trastuzumab, six had already received lapatinib, and three pertuzumab as well. Three patients had partial remission of BM, and two patient had stable disease lasting for ≥6 months; two further patients had stable disease for <6 months while three progressed despite treatment. At 8.5 months median follow-up, intracranial PFS was 5 months, and median OS from initiation of T-DM1 was not reached. Local treatment of BM remains the standard of care; lapatinib plus capecitabine is currently the best established systemic therapy option. Still, T-DM1 apparently offers relevant clinical activity in BM and further investigation is warranted. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
