About Raja Flores, MD

Raja M. Flores, MD is a world-renowned surgeon with specialized expertise in mesothelioma, lung cancer, and esophageal cancer. He is the Chief of Thoracic Surgery at The Mount Sinai Medical Center and the Director of the Thoracic Surgical Oncology Program at Mount Sinai Cancer Center.

Dr. Flores helped pioneer the use of intraoperative chemotherapy for mesothelioma cancers of the esophagus or lung. He has participated in and led a number of major studies including clinical trials of neoadjuvant gemcitabine and cisplatin followed by extrapleural pneumonectomy and high dose radiation and a multicenter trial of neoadjuvant alimta/cisplatin, extrapleural pneumonectomy, and high-dose radiation which is designed to improve outcomes.

He is also a leading international educator on VATS lobectomy, a minimally invasive approach that uses three small incisions in the treatment of lung cancer. He established the current program for this procedure at Memorial Sloan-Kettering Cancer Center, where he previously worked, and he published two sentinel studies establishing its oncological effectiveness by demonstrating equivalent survival and recurrence rates but fewer complications and shorter hospital stays when compared to standard thoracotomy.

An author of over 150 peer-reviewed manuscripts, reviews, books, and book chapters, he has given over 100 lectures worldwide. His work has also been published in many journals, including The Journal of Clinical Oncology, Journal of Thoracic Oncology, The Annals of Surgery, The Annals of Thoracic Surgery and Vascular Surgery.

After earning an undergraduate degree in biochemistry from New York University, Dr. Flores attended the Albert Einstein College of Medicine, receiving his M.D. in 1992. He then spent five years at Columbia-Presbyterian Medical Center pursuing his General Surgery Internship and General Surgery Residency. Following that, he completed a Thoracic Oncology Clinical Research Fellowship at Brigham and Women’s Hospital/Dana Faber Cancer Institute/CALGB in Boston, and his Cardiothoracic Surgery Residency at Brigham and Women’s Hospital, Harvard Medical School. He also received a Masters in Biostatistics from Columbia University.

Over the past decade, Dr. Flores has held positions at Memorial Sloan-Kettering Cancer Center, most recently as Associate Professor of Cardiothoracic Surgery. He belongs to numerous medical and surgical societies and serves on several editorial boards.
