For years, patients have been warned that combining grapefruit juice with medications can have a dangerous result. Grapefruit juice interferes with the breakdown of certain drugs in the human body, often causing the level of a drug to increase in potency. But physician-scientists at the University of Chicago Medical Center saw potential in this interaction.
Cancerous tumors need blood vessels to grow, but a drug with promise for cancer treatment can inhibit this development. When taken by mouth, however, less than 15% of this drug is absorbed by the body. University of Chicago Medical Center physicians believed that if they could find a way to increase the strength of the drug, if they could get more of the drug to reach its target — the tumor — they could stop the cancer from advancing.
In a study directed by clinicians at the University of Chicago Medical Center, they’re doing just that. This drug, when washed down with a glass of grapefruit juice, is now showing promise in patients with advanced tumors for which there are no other treatment options. Could a piece of fruit have the potential to forever change the way cancer is treated?
At the University of Chicago Medical Center, we ask questions like this every day — in the halls of our hospitals, and in our labs — as we work to unlock the cure for cancer tomorrow through groundbreaking clinical research, and advance patient care today with pioneering surgical, radiation and chemotherapy treatments and procedures.
As one of only two programs in Illinois designated by the National Cancer Institute as an official Comprehensive Cancer Center, the University of Chicago Medical Center is consistently ranked among the top cancer treatment centers in the country. Our unique approach to care allows us to offer patients innovative and minimally invasive treatment options, such as gene therapy, organ-sparing surgical procedures and more.

We offer advanced diagnosis and treatment for all types of cancer:


When doctors in New Orleans found a volleyball-sized tumor intertwined with major organs and arteries in 2-year-old Makayla Dillon’s abdomen, her family couldn’t find a surgeon who was willing to remove it. The surgery was deemed to be too risky by every doctor the family consulted. And Makayla was left with little hope of survival.
It wasn’t until her mother brought her to the University of Chicago Comer Children’s Hospital that Makayla finally received the treatment she needed. Here, our pediatric surgeons devised a plan that would allow them to safely remove Makayla’s tumor, and end her fight with cancer.
Jenna Mosconi began experiencing extreme difficulty eating and digesting food, and was losing drastic amounts of weight — fast. Several other doctors incorrectly diagnosed Jenna with heartburn, digestive problems and even anorexia, but our physicians discovered that she had a rare heart condition called Median Arcuate Ligament Syndrome, or MALS. With an accurate diagnosis, our surgeons were able to use minimally invasive laparoscopic surgery to remove from Jenna’s heart a misshapen artery, which was impeding blood flow to her digestive tract.
At the University of Chicago Comer Children’s Hospital, we understand that operating on children requires more than just smaller tools. It requires a different way of thinking. Our pediatric surgeons are encouraged and empowered to think like scientists, to take on the complex cases that no one else will, and to use the novel and minimally invasive surgical techniques and technologies that will give kids a fighting chance. With groundbreaking surgical approaches to treat the following:
At Comer Children’s Hospital, we also offer hope for children with difficult-to-treat neurological diseases, spinal disorders, hip diseases, cerebral palsy, and problems requiring plastic and reconstructive surgery.

Snow fleas are insects that, as the name suggests, make their home in the snow. After studying these insects, researchers have discovered that the source of their tolerance to cold is a protein with characteristics similar to anti-freeze. Based on these findings, physician-scientists at the University of Chicago Medical Center are developing a way to harness the power of this protein to store organs at lower temperatures without damaging healthy tissue. If successful, this protein could enable us to transport organs longer distances and give the gift of time to more patients waiting for liver transplants.
As the oldest liver transplant program in the Midwest and the fourth oldest in the nation, the University of Chicago Medical Center has a rich history of innovation in transplant care. Since performing the first human organ transplant in an animal model, our team has led the way, offering an unmatched level of expertise and clinical capabilities.

There is no cure for the common cold, but what if a cold virus could be used to help fight other diseases? Physician-scientists at the University of Chicago Medical Center have discovered a way to use radiation to cause a particular gene to secrete a compound — tumor necrosis factor — that can stop tumor growth in pancreatic cancers. But getting the tumor necrosis factor to its target — the tumor — presented a challenge, until we found a way to bond the gene to a cold virus, allowing the gene to spread to all the right places. This new discovery could help physicians at the University of Chicago Medical Center’s gastrointestinal oncology program fight some of the most difficult cancers.
With world-renowned programs in both gastroenterology and cancer care, and a commitment to groundbreaking clinical research, the University of Chicago Medical Center is leading the way in the diagnosis, treatment and management of a wide variety of cancers of the digestive system.

Pulmonary hypertension (PH) is a devastating heart condition for which there is no known cure. But after studying the cells responsible for PH, physician-scientists at the University of Chicago Medical Center realized that they are strikingly similar in nature to cancer cells.
In both diseases, cells grow abnormally. In cancer, this causes the tumor to increase in size and spread throughout the body; in PH, the cell growth causes thickening in the arteries that supply the lungs, constricting breathing and blood flow.
Because cancer medications work to shrink the abnormal cell growth of tumors, our physician-scientists believed they could possibly slow the growth and thickening of pulmonary artery walls as well. This unconventional thinking led our physicians to begin looking for better treatment options for PH, giving new hope to patients suffering from this painful and debilitating heart condition.

Bacteria have long been seen as something harmful to our bodies — tiny microorganisms that can cause illness and infectious diseases. But in recent years, physicians and scientists have discovered that bacteria can actually be beneficial to the human body. In fact, a study conducted by the University of Chicago Medical Center shows that bacteria might even be able to prevent illness and disease.
While studying Crohn’s disease and Colitis, two painful, life-altering gastrointestinal (GI) disorders, scientists at the University of Chicago Medical Center observed that patients without the presence of healthy bacteria in their GI tract were at a heightened risk to develop these diseases. Based on this finding, our team believes that a certain species of intestinal microflora could be used to prevent Crohn’s disease, Colitis and other GI disorders — a discovery that could revolutionize how GI diseases are treated.
At the University of Chicago Medical Center, the physician-scientists that make up our gastroenterology team are recognized worldwide for their ability to take what they learn in the lab and use it to advance patient care, pioneering novel treatments and procedures for patients with digestive and bowel diseases. Among other distinctions, our team was responsible for discovering the first gene that increases the risk of Crohn’s disease, and today conducts more than 20 clinical trials for IBD, in addition to the groundbreaking research into the causes and potential cures of Ulcerative Colitis and Crohn’s disease. This year, we will perform more than 9,000 colonoscopic procedures and conduct over 300 GI cancer trials.

Bone marrow transplants are a proven way to treat leukemia. But in the past, they could only be performed if the donor and recipient had a 100% DNA match — something only biological siblings share. Because a bone marrow recipient’s body will reject any genetic material that does not match perfectly, parents were unable to act as donors for their children, as they only share 50% of their kids’ DNA.
Today, physician-scientists at the University of Chicago Comer Children’s Hospital are working to change that — with a pioneering new procedure that gives parents the ability to donate bone marrow to their children. By using the power of magnets to filter a parent’s DNA, extracting the matching genetic material needed for a transplant, the University of Chicago Comer Children’s Hospital is giving kids suffering from leukemia new hope.
With the region’s most experienced physicians in bone marrow transplant from parent to child, and a pediatric oncology program that is closely linked with an adult program, the University of Chicago Comer Children’s Hospital provides a level of expertise that is simply unparalleled.
Our physicians, surgeons, researchers and specialists bring the insight that comes from working with both children and adults, in our labs and in our hospitals, to everything they do.
