Overview

The Sarcoma/Oncology Computational Biology Laboratory is under the direction of Dr. Dimitrios Spentzos, MD, M.MSc. The laboratory collaborates with a number of oncology, radiation oncology, and pathology investigators at the Center for Sarcoma and Connective Tissue Oncology and the Mass General Cancer Center. It also works closely with other Harvard Medical School research affiliates such as the Center for Cancer Computational Biology (directed by John Quackenbush, PhD) and many faculty collaborators at the Department of Biostatistics, at the Dana Farber Cancer Institute.

The mission of the laboratory is to uncover the mechanisms of tumor behavior and understand how they show different responses to conventional and novel treatments, but studying genome-wide DNA, RNA, microRNA, and methylation profiles and determining their relationship with biologic and clinical outcomes. We utilize microarray and deep sequencing platforms and advanced biostatistical and computational analyses methods to detect biologic and clinical signal in highly dimensional and often noisy genomic data. Our studies aim to develop molecular patterns that can function as biomarkers to guide treatment strategies and can also be used as functional “read outs” of response to therapy.

In addition, we are exploring novel molecular classification approaches to sarcomas based on genomic profiling, that can complement traditional histology-based classification, as it is recognized that if often does not capture the entire biologic diversity of sarcomas or their differential clinical response patterns. For example, novel insights into osteosarcoma subtypes may be gained by recent work on the role of a non-coding 14q32 chromosome based cluster in osteosarcoma. Finally, in close collaboration with our computational biology and bioinformatics affiliate centers we are interested in assisting in the development and implementation of novel bioinformatics approaches to analyze highly dimensional genomic data in a clinically and biologically relevant manner.

Our laboratory is funded by the NIH and is also part of Cancer Center efforts to utilize generous philanthropic contributions to cancer research at Mass General.

Research Positions

The laboratory generally employs research assistants with a clear academic orientation, who typically move on to graduate (PhD, MD, or MD/PhD) studies, and we are in the process of expanding with new and higher-level post graduate positions. In addition, we provide mentorship to undergraduate and graduate students who are interested to participate in our research.
