BiographyDr. Choy is the Director of Sarcoma Research at the Division of Hematology Oncology at MGH. He specialized in the medical management of patients with sarcomas, gastrointestinal stromal tumors, chordomas, and desmoid tumors.  He works closely with a team of world class surgical, orthopedic, and radiation oncologists as well as connective tissue pathologists and radiologists to provide optimal care for his patients.  He directs a clinical trials program at the MGH Center for Sarcoma and Connective Tissue Oncology that includes 9-12 active phase I-III clinical trials.  He also maintains an active scientific research program that investigates diverse areas of sarcoma therapy ranging from the use of nanotechnology and other translational research tools aimed at developing new targeted therapies for treating cancers to preclinical studies using cell lines and animal models to better understand the molecular basis of sarcoma biology. 

ResearchDr. Choy is dedicated to research, teaching, and caring for patients with sarcomas, chordomas, and desmoid tumors. His research endeavors include basic laboratory research, translational studies, and clinical trials all aimed at improving care for cancer patients.

In the laboratory, Choy collaborates with Dr. Zhenfeng Duan and Dr. Francis Hornicek to study the genetics and biology of chemotherapy resistance.In collaboration with investigators at MIT and DFCI, Choy has collected 100 osteosarcoma tumor samples and genotyped them for over one thousand mutations occurring in oncogenes and tumor suppressor genes. He has currently validated 15 mutations and these findings were presented at the international Connective Tissue Oncology Society (CTOS) meeting in November 2009. Choy also holds joint collaborative sessions with investigators at MIT, sponsored by the Koch Institute, to explore further translational projects to benefit sarcoma patients.

Choy has led the growth of an active clinical research program in sarcomas, expanding the number of clinical trials to 12 trials currently, increasing participation in DF/HCC phase I programs, and increasing the overall enrollment rate onto studies. This success in growing our sarcoma program has led to five abstracts that were presented at this year's annual ASCO meeting.Choy's work has been recognized by a career development award from Harvard Catalyst.
