I have helped develop a number of the agents now approved to treat lymphoma — including 131I-tosituomab/tositumomab, bortezomib, and pralatrexate — and through clinical studies I am evaluating the benefits of novel combinations of agents. In another area of research I am working to improve the prognostic value of patients’ pathology specimens using computer-aided image analysis. I have published more than 100 papers on lymphoma research in journals such as Blood, Journal of Clinical Oncology, and Clinical Cancer Research.
I am involved in several national organizations that provide information about lymphoma treatment and fund laboratory and clinical research. I am chairperson of the Non-Hodgkin Lymphoma Guidelines panel of the National Comprehensive Cancer Network and vice chairperson of the Lymphoma Core Committee of the Cancer and Leukemia Group B. I am also a member of the scientific advisory board of the Lymphoma Research Foundation.
A lymphoma specialist is a doctor with special training in diagnosing and treating lymphoma.

The entire Lymphoma team has consistently provided exceptional care since 2006.
I have been seeing Dr. Zelenetz for close to 30 years. He is always good at explaining complex things and ensures I understood. He has a great bedside manner.
Both the Koch and Nassau facilities are the best run medical facilities I have ever encountered. My wife and daughter work in the medical industry so I am exposed to many facilities. MSK is the model to follow.
Dr Zelenetz is simply the best. As is his team.
The MSK team impresses me with their professionalism and efficiency at every visit.
