Biography

Baran D. Sumer, M.D., is a Dallas head and neck cancer surgeon and otolaryngologist at UT Southwestern Medical Center. He specializes in head and neck cancer surgery, transoral robotic surgery, transoral laser surgery, microvascular reconstruction, skull base surgery, and multidisciplinary treatment planning for complex head and neck tumors. Dr. Sumer is Professor and Chief of the Division of Head and Neck Oncology at UT Southwestern in the Department of Otolaryngology and Director of the Head and Neck Oncology Disease Oriented Team at Simmons Comprehensive Cancer Center.

Patients and referring physicians often seek Dr. Sumer for advanced surgical care of head and neck cancers where tumor control, swallowing, speech, appearance, and quality of life are major concerns. His clinical and research work includes minimally invasive robotic and endoscopic approaches, fluorescence-guided surgery, cancer imaging, and technologies designed to improve precision in head and neck cancer surgery.

Dr. Sumer earned his medical degree at Case Western Reserve University. He then completed an internship in general surgery, a residency in otolaryngology, and a fellowship in head and neck oncologic surgery and microvascular reconstruction at Washington University School of Medicine in St. Louis.

Dr. Sumer serves on committees for NRG Oncology, the American Head and Neck Society (AHNS), and the World Molecular Imaging Society (WMIS) and served as a permanent member of the Innovations in Nanosystems and Nanotechnology (INN) study section (formerly NANO) for the National Institutes of Health (NIH) Center for Scientific Review between 2020-2024.

He has participated in a wide variety of research studies devoted to advancing diagnostic and therapeutic techniques and technologies for head and neck cancer, such as fluorescent imaging, biosensing, hyperspectral imaging, photodynamic therapy, and image-guided surgery.

His collaboration with another UT Southwestern faculty member, Jinming Gao, Ph.D., has led to several inventions in their joint lab, including a pH-sensitive nanoparticle that can be used to deliver therapeutics and imaging agents specifically to cancers. Drs. Sumer and Gao's work with the pH nanosensor has resulted in a European phase 1 clinical trial, completed in 2019, and a phase 2 clinical trial in the U.S. for cancer patients with peritoneal metastases, completed in 2023.

The fluorescent nanoparticle they co-developed for these clinical trials illuminates cancer cells during surgery, potentially allowing surgeons to visualize the tumors more accurately. This nanoparticle, pegsitacianine (ONM100), is manufactured by OncoNano Medicine, a biotechnology company co-founded by Dr. Sumer and Dr. Gao.

Dr. Sumer is currently the PI of another phase 2 clinical trial, the ILLUMINATE trial, which is testing the ability of pegsitacianine to identify unknown primary cancers of the head and neck and to fluorescently label head and neck cancers undergoing robotic surgery. The ILLUMINATE trial is funded by an R01 grant from the NCI.

Among numerous recognitions, honors, and awards, Dr. Sumer has been recognized as among the best otolaryngology physicians in North Texas by D Magazine. He is also the recipient of a Texas Instruments Corporate Award Research Gift, the Triological Society Francis Lederer FUSION Grant for Nanotechnology Research, and the SEBM Best Paper Award in the Alan MacDiarmid Interdisciplinary Research Society for Experimental Biology and Medicine.

Dr. Sumer serves as principal investigator and co-investigator on several research projects funded by the National Institutes of Health (NIH) and the National Cancer Institute (NCI).

Meet Dr. Sumer

Head and Neck Cancer Specialist in Dallas

Baran D. Sumer, M.D., is a head and neck cancer surgeon in Dallas who treats patients with complex tumors of the mouth, tongue, throat, tonsils, voice box, neck, and skull base. At UT Southwestern Medical Center, he leads a multidisciplinary team dedicated to treating head and neck cancers while preserving critical functions such as speaking, swallowing, and breathing, as well as facial appearance, whenever clinically possible.

Because the head and neck contain many important nerves, blood vessels, and structures, treating cancers in this region requires specialized expertise. Dr. Sumer and the UT Southwestern team offer advanced surgical treatments, radiation therapy, chemotherapy, targeted therapies, reconstructive surgery, rehabilitation, and supportive care tailored to each patient.

Expertise in Robotic and Minimally Invasive Surgery

Dr. Sumer has particular expertise in transoral robotic surgery (TORS), transoral laser surgery, and other minimally invasive techniques. For appropriately selected patients, these procedures allow tumors to be removed through the mouth, avoiding external incisions in the neck or face and minimizing damage to surrounding healthy tissue.

“These procedures tend to be much better tolerated by patients than traditional surgery, which can often result in significant problems with swallowing and speech,” Dr. Sumer says. “We perform endoscopic, laser, and robotic procedures through the mouth, requiring no external incision in selected cases.”

Dr. Sumer made medical history in North Texas as the first surgeon in the region to perform a TORS procedure to remove a throat malignancy. Research has continued to validate this approach. The multi-institutional E3311 study, published in the Journal of Clinical Oncology in 2022, demonstrated that TORS can help appropriately selected patients with resectable, p16-positive oropharyngeal cancer safely receive less-intensive postoperative radiation and, in some cases, avoid chemotherapy.

Recognized as a D Magazine Best Doctor, Dr. Sumer also has extensive experience treating complex and recurrent head and neck cancers, including patients who may have been told elsewhere that their tumors were inoperable or would require highly disabling surgery.

Advanced Head and Neck Reconstruction

When tumor removal requires reconstruction, Dr. Sumer and UT Southwestern’s reconstructive surgeons use advanced techniques, including microvascular free-flap reconstruction, to restore form and function. Treatment planning focuses not only on eliminating the cancer but also on helping patients retain or recover their ability to speak, swallow, eat, breathe, and interact comfortably with others.

“We have treated patients who were told they would need their entire tongue removed or would require a permanent opening in their neck to breathe,” Dr. Sumer says. “In selected cases, we have been able to cure the cancer while preserving swallowing and speech.”

Comprehensive, Multidisciplinary Care

UT Southwestern’s head and neck cancer program brings together specialists in:

“Physicians play an important role in treating head and neck cancer, but it is the multidisciplinary care, counseling, and rehabilitation provided by the entire team that ultimately help patients achieve the best possible quality of life,” Dr. Sumer says.

That emphasis on quality of life continues throughout treatment and recovery. Patients frequently return to report that they can eat in restaurants again, enjoy meals with family and friends, and participate fully in everyday life.

Research and Innovation

In addition to his clinical practice, Dr. Sumer conducts research aimed at making head and neck cancer surgery more accurate, effective, and less invasive. His research interests include image-guided surgery, fluorescence-guided surgery, cancer imaging, nanotechnology, surgical robotics, and precision approaches to identifying and removing head and neck tumors.

Through this combination of advanced surgery, reconstruction, multidisciplinary care, and research, Dr. Sumer and the UT Southwestern team provide comprehensive treatment for patients seeking specialized head and neck cancer care in Dallas, North Texas, and beyond.
