Lymphoma Specialists

Chairman and Professor Emeritus
Duke Department of Radiation Oncology  

The contributions of Dr. Prosnitz to the field of radiation oncology and to Duke itself are far reaching and transformative. He was a pioneer in demonstrating the effectiveness of lumpectomy and radiation rather than mastectomy in early stage breast cancer treatment, a process now considered standard and offered to more than 100,000 women each year in the U.S. He also pioneered combination therapies of radiation and chemotherapy for malignant lymphomas and other cancers.  On the humanitarian front, Dr. Prosnitz helped to develop a modern cancer center and radiation therapy facility in Taiwan and was a leader in the creation of Caring House in Durham—a home that provides adult cancer patients and accompanying caregivers with a comfortable, supportive, and affordable place to stay during outpatient treatment at the Duke Comprehensive Cancer Center.

Attending Physician, Radiation Oncology, Brigham And Women’s Hospital

The area of my clinical research is on treatment outcome of patients diagnosed with Hodgkin’s lymphoma and non-Hodgkin’s lymphoma. I especially focus on treatment side effects and late effects of cancer therapy, including second malignancies, cardiopulmonary complications and quality of life of long-term survivors of lymphoma.

Her recent publications include the following topics: 

• ILROG guidelines on the use of radiotherapy for HL, relapsed lymphoma, NK/T cell lymphoma, nasal type, multiple myeloma,  and on alternative radiation fractionation strategies for hematologic malignancies during COVID pandemics
• Low-dose radiation therapy for indolent lymphoma
• Radiotherapy in the management of classical HL, nodular lymphocyte predominant lymphoma, cutaneous lymphoma, relapse/refractory NHL, 
• Late effects of radiotherapy for Hodgkin lymphoma including second malignancy and cardiovascular disease risks

Radiation Oncologist, Massachusetts General Hospital

Chirayu G. Patel,  MD, MPH is a radiation oncologist at the Massachusetts General Hospital and specializes in hematologic malignancies, including Hodgkin and Non-Hodgkin lymphoma, multiple myeloma, and leukemia.

A native of Massachusetts, Dr. Patel graduated summa cum laude from the University of Pennsylvania, attended medical school at the Warren Alpert Medical School of Brown University, and obtained his Master of Public Health in Quantitative Methods from the Harvard School of Public Health. He also completed a prestigious Howard Hughes Medical Institute fellowship at the National Institutes of Health during medical school, where he did research on acute myeloid leukemia.

Following his schooling, Dr. Patel completed an internship at the University of Pittsburgh Medical Center and radiation oncology residency at Vanderbilt University Medical Center, where he was the Chief Resident during his final year. During residency, he was a recipient of the highly competitive ASTRO (American Society for Radiation Oncology) Resident Seed Grant, which he used to study tumor metabolism in the laboratory.

After completing his clinical and research training, he joined the faculty of Massachusetts General Hospital, where he specializes in radiation oncology involving hematologic malignancies and conducts clinical research to advance cancer therapy, as well as improve the cancer survivorship experience.
