Research area

Advancing new treatments and prediction strategies for HER2-positive breast cancer patients with brain metastasis.


The spread of breast cancer to the brain has a significant impact on the quality of life and survival of MBC patients and remains an urgent clinical problem, one that Dr. Lin has been focused on solving. She has led two significant clinical trials that led to FDA approval of new drugs for patients with HER2-positive breast cancer that has spread to the brain. Dr. Lin is now focused on assessing the genomic alterations that occur with the development of breast cancer-related brain and central nervous system metastases. For these studies, her team utilizes the Ending Metastatic Breast Cancer for Everyone (EMBRACE) research study database which contains data from over 2,000 MBC patients. In related studies, Dr. Lin and her colleagues are examining efficacy of antibody-drug conjugates (ADCs) in patients with central nervous system metastases. Both investigations will address the urgent need to find more effective treatments for both early-stage and metastatic HER2-positive breast cancer.

Progress Thus Far

To identify genomic predictors of brain and central nervous system metastases, Dr. Lin has completed the genomic sequencing of 778 primary tumor samples in patients with MBC with known sites of metastatic involvement.  Other studies, conducted in collaboration with fellow BCRF-investigator Dr. Jean Zhao, have demonstrated that the ADC trastuzumab deruxtecan has intracranial activity in laboratory models, providing a rational for clinical testing.  

What's next

Dr. Lin and her colleagues will proceed with analysis of the genomic sequencing data to identify potential genomic predictors of breast cancer-related development of brain or central nervous system metastases. In the next year, Dr. Lin will also launch a prospective, multicenter study to test trastuzumab deruxtecan in patients with progressive breast cancer brain metastases.


Dr. Nancy Lin is a medical oncologist at Dana-Farber Cancer Institute (DFCI) and Associate Professor of Medicine at Harvard Medical School. Dr. Lin received her medical degree at Harvard Medical School and subsequently completed her residency in Internal Medicine at Brigham & Women's Hospital and a fellowship in Hematology/Oncology at Dana-Farber/Partners Cancer Care. Since 2018, she has served as Associate Chief of the Division of Breast Oncology at DFCI.

Dr. Lin's focus is on developing novel targeted therapies for patients with advanced breast cancer and exploring mechanisms of drug resistance, with a particular interest in patients with breast cancer that has metastasized to the brain. Dr. Lin is leading multiple ongoing and planned clinical trials evaluating a variety of targeted approaches in patients with metastatic breast cancer. Her work is highly collaborative and involves close working relationships with clinicians, laboratory investigators, and patient advocates. Dr. Lin's honors and awards include a Young Investigator Award and Career Development Award from the American Society of Clinical Oncology. She is a member of the Massachusetts Medical Society, American Society of Clinical Oncology, Alliance for Clinical Trials in Oncology, and Translational Breast Cancer Research Consortium.
