Medical Oncology

John P. Leonard, M.D.

Our program is internationally recognized for its efforts to enable patients with non-Hodgkin's lymphoma, Hodgkin's disease, multiple myeloma, and related disorders to have the best possible clinical outcome, including cure when possible. For many of these disorders, chemotherapy and radiation therapy have been the primary treatments, and can often be quite successful. Patients come to our center for evaluation and treatment from throughout the New York metro area, as well as other parts of the country and world.

At the NewYork-Presbyterian Hospital/Weill Cornell Center for Lymphoma and Myeloma, where I am Clinical Director, we have developed an outstanding team of physicians (including medical oncologists, radiation oncologists, pathologists, and others), nurses, and related health care personnel in order to optimally serve patients with these disorders. As we have a clinical focus in these areas, we are well versed in standard therapies, as well as their usual complications. Our experience with lymphoma and other treatment regimens is important to many patients undergoing therapy.

However, we are not satisfied with current outcomes for patients with lymphoma and myeloma as a group. We are working diligently to try to improve cure rates, as well as to improve remissions and extend life for other patients, while maintaining and improving its quality. Many of our patients are interested in clinical trials for their disorder, often in addition to "standard" therapies. Our focus has been primarily on "immunotherapies," which can work with the immune system to kill tumor cells. However, we collaborate with laboratory scientists at Weill Cornell, biotechnology and pharmaceutical companies, and other leading lymphoma research groups both nationally and internationally to bring the most promising developments to our patients. 

Many of our clinical trials are offered in conjunction with the National Cancer Institute, and our research program is otherwise in part also supported by the National Institutes of Health. Some clinical trials can be administered in conjunction with community oncologists, in order to minimize inconvenience and travel for the patient. Additional details are located in the "Research Profile" section on this page of the website.

Lymphomas as a group are a complex set of disorders. While many patients are treated here as their primary oncologist, others come for a second opinion while having their primary oncologic care with a local physician, having us follow along as needed. Others are referred (or otherwise seek care) for access to novel agents as part of clinical trials. We are pleased to provide care in any fashion that would be of assistance to patients, in order to help them achieve the best possible therapeutic results. Patients or physicians with any questions about our lymphoma and myeloma care programs, clinical trials, or related issues should feel free to contact us for more information.
