Biography

Dr. Marks, Distinguished Professor in Radiation Oncology at the University of North Carolina at Chapel Hill, received a B.S. in Chemical Engineering (Cooper Union 1981), an M.D. (University of Rochester, 1985), had residency training at Massachusetts General Hospital, and was faculty at Duke for 19 years and joined UNC in 2008 as Chair of Radiation Oncology.

Clinically he focuses on breast and lung cancer. His research aims to improve the therapeutic ratio of radiation, largely through better understanding radiation-induced normal tissue injury. In particular, he has extensively studied radiation-induced damage in the lung and heart. He helped to lead an international effort to develop dose/volume/outcome standards called QUANTEC.

Dr. Marks is interested in human-factors engineering, has studied the frequency/causes of “human-errors” in the clinic, and has implemented systems aimed to reduce errors. He serves on several national committees aimed to improve patient safety. He has written many papers and recently a book about this sensitive issue.

Physicians experience increased effort, uncertainty in cross-coverage of radiation oncology patients

RxPG News  online

2013-09-25

In a paper presented at the 2013 American Society for Radiation Oncology conference, study authors Prithima Mosaly, PhD, and Lukasz Mazur, PhD, assistant professors in the UNC Department of Radiation Oncology; Bhishamjit Chera, MD, assistant professor of radiation oncology and Lawrence Marks, MD, Sidney K. Simon Distinguished Professor of Oncology Research and Chair, found a significant decrease in performance and confidence when physicians were asked to plan the treatment of an unfamiliar patient...

New QUANTEC guidelines for safe treatment of cancer with radiation therapy

News Medical  online

2010-03-03

"The new standards have resulted from a systematic review of radiation therapy dose/volume/outcome data on 16 organs. The new data was made possible by the more general use of 3D imaging during radiation planning. These new standards provide a logical framework to assess the risks of complex 3D doses that we now routinely consider," said Lawrence B. Marks, M.D., chair of the department of radiation oncology and co-editor of the QUANTEC study...

Use of normal tissue complication probability models in the clinic International Journal of Radiation Oncology * Biology * Physics

2010 ABSTRACT: The Quantitative Analysis of Normal Tissue Effects in the Clinic (QUANTEC) review summarizes the currently available three-dimensional dose/volume/outcome data to update and refine the normal tissue dose/volume tolerance guidelines provided by the classic Emami et al. paper published in 1991. A “clinician's view” on using the QUANTEC information in a responsible manner is presented along with a description of the most commonly used normal tissue complication probability (NTCP) models. A summary of organ-specific dose/volume/outcome data, based on the QUANTEC reviews, is included...
