“There are a lot of advantages to doing research here, especially with a disease like mesothelioma,” Hassan said. “Everything you need to succeed is right here.”

As part of the National Institute of Health (NIH), the NCI is funded well enough to allow for more specialization, which Hassan has enjoyed. It’s not usually the case in a university medical center. At many facilities, mesothelioma research must be juggled with other, more common diseases, pulling researchers in different directions.

Hassan is in the midst of five different trials involving mesothelioma, still working toward the development of a better program for the treatment and diagnosis of a cancer that continues to frustrate much of the medical community.

We have a very strong mesothelioma program here, and we are getting promising results. The intellectual environment and everything else is here.”

– Dr. Hassan

Although progress is being made, there still is no cure for mesothelioma, which is diagnosed in an estimated 3,000 patients annually. United States military veterans comprise an estimated one-third of those diagnosed.

“This is such a rare disease, which sometimes makes it difficult to conduct trials – there aren’t enough patients for a big study – but with a rare disease the progress you make really has an impact,” he said. “It’s very rewarding.”

Promising Therapies

Hassan is working with tumor vaccines and new immunotherapy agents, novel therapies he hopes will move everyone a little closer to finding a cure. The trial with SS1P has him particularly enthused.

I’m confident in the advances we’re making. There are several good drug trials going on. From just a few years ago, we’re making significant progress.”

– Dr. Hassan

The NCI makes it easier to get patients for studies because all patients are admitted at no cost, to either the patient, or his insurance company. Certain travel expenses are covered, too, which encourages mesothelioma patients to be part of the NCI program.

“Most oncologists see maybe one mesothelioma case a year, or only a few in their lifetime. They just aren’t aware of what is available for the patients,” Hassan said. “That is where we can help. We see a lot of these.”

Quick Fact

Dr. Hassan earned the American Society of Clinical Oncology’s Career Development Award.

His interest in mesothelioma began during a fellowship at the NCI, which finished in 1997. He left to join the faculty at the University of Oklahoma for five years before returning in 2002, intensifying his quest to make a difference in the field.

“My interest in this disease started in the lab. And it just grew over time. And now it’s more intriguing than ever.”


In 2011, Hassan published “Chemotherapy and Targeted Therapies for Unresectable Malignant Mesothelioma”, “In Vivo Imaging of Human Malignant Mesothelioma Grown Orthopedically in the Peritoneal Cavity of Nude Mice,” and “The Development and Characterization of a Human Mesothelioma in Vitro 3D Model.”
