Meet Dr. Yull Arriaga
Medical Oncologist Specializing in Liver and Bladder Cancer

Yull Arriaga, M.D., is focused on the future and how to help give his patients better cancer treatment and improve their quality of life.

Dr. Arriaga is a hematologist/oncologist and Assistant Professor of Internal Medicine - Hematology/Oncology at UT Southwestern Medical Center’s Harold C. Simmons Cancer Center. He has been recognized as a Best Doctor by D Magazine.

It’s very important for me to take care of my patients with compassion and truthfulness. I pay close attention to what they say they’re going through, and I combine that with science and evidence-based knowledge and experience.” 

Dr. Arriaga believes that a multidisciplinary approach is the best way to treat patients with cancer. He serves on the gastrointestinal and genitourinary disease-oriented teams at Simmons Cancer Center and treats adult patients with GI and GU malignancies, specializing in liver cancer and bladder cancer, as well as pancreatic, stomach, colorectal, biliary tree, urinary, prostate, and kidney cancers.

“Cancer care is a well-coordinated team effort,” Dr. Arriaga says. “Each multidisciplinary group is made up of experts who plan the patient’s treatment up front. It’s almost like designing a roadmap for their care.”

He subscribes to four basic principles in his daily medical practice: (1) To do what’s best for his patients; (2) keep their safety in mind; (3) be honest; (4) and offer hope.

Dr. Arriaga is heavily involved in clinical trials research. He is the local principal investigator for a multi-institutional study on a new combination of targeted drugs for patients with metastatic pancreatic neuroendocrine tumors. Another project he is directly involved in will evaluate the safety, efficacy, and metabolic effects of a known oral diabetic drug for patients with advanced pancreatic cancer.

His ultimate goal is to treat the majority of his patients in novel clinical trials, particularly those with advanced cancers.

“That’s the only way to advance the field of cancer,” he says.
