Meet Dr. Merkow
In order to provide his patients with the best solution(s), Dr. Merkow offers both nonsurgical and surgical options. His treatments include regional cancer therapies, such as hepatic artery infusion (HAI) pump chemotherapy, a technique that supplies high doses of chemotherapy directly to the liver. This therapy is used to kill any remaining cancer cells after visible tumors have been surgically removed, as well as to convert someone from unresectable (all tumors cannot be removed) to resectable (all tumors are able to be cleared from the liver). He also provides other liver directed therapies, such as ablation, designed to selectively target liver tumors without injuring nearby healthy tissue.
In addition to regional therapies, Dr. Merkow performs minimally invasive and robotic surgery to treat cancer, offering accuracy and precision while removing life-threatening tumors. This allows his patients to recovery faster with less pain and scarring so they can get back to their daily lives sooner.
Along with his dedication to his clinical practice, Dr. Merkow is passionate about advancing treatment through clinical research and making surgery and cancer care delivery safer, more efficient and patient-centered. His research focuses primarily on surgical outcomes, quality improvement and patient safety, which has been published in over 150 peer-reviewed articles in highly respected, medical journals, like the Journal of the American Medical Association (JAMA), Journal of the National Cancer Institute (JNCI), British Journal of Quality and Patient Safety, Annals of Surgery, Annals of Surgical Oncology and more. With his research expertise, Dr. Merkow will join the University of Chicago’s Health Services Research Center.
Dr. Merkow is active, and has held leadership roles, in several national healthcare organizations, including serving as chair of the Association for Academic Surgery Clinical and Health Services Research Committee. Additionally, with healthcare constantly evolving, he provides clinical training to medical students, residents and fellows, mentoring them as they embark on their medical careers.

Some of our physicians and health professionals collaborate with external pharmaceutical, medical device, or other medical related entities to develop new treatments and products to improve clinical outcomes for patients. In some instances, the physician has ownership interests in the external entity and/or is compensated for advising or speaking about the entity’s products or treatments. These payments may include compensation for consulting and speaking engagements, equity, and/or royalties for products invented by our physicians. To assure objectivity and integrity in patient care, UChicago Medicine requires all physicians and health professionals to report their relationships and financial interests with external entities on an annual basis. This information is used to review relationships and transactions that might give rise to potential financial conflicts of interest, and when considered to be significant a management plan to mitigate any biases is created.

Hepatic Artery Infusion (HAI) Pump Chemotherapy for Liver Metastases
Hepatic artery infusion pump chemotherapy, or HAI, is an advanced treatment for tumors that have spread to the liver due to metastatic colorectal cancer or metastatic bile duct cancer. HAI is a powerful tool to shrink liver tumors and reduces the risk of tumor recurrence.
Hepatic Artery Infusion Pump Chemotherapy, or HAI, is an advanced treatment for tumors that have spread to the liver due to metastatic colorectal cancer or metastatic bile duct cancer. HAI is a powerful tool to shrink liver tumors and reduces the risk of tumor recurrence.
The hepatic artery infusion pump is a wireless metal pump that is placed inside the abdominal wall during a surgical procedure. The device is about the size of a hockey puck. The pump is connected to the liver via a small tube placed into a blood vessel connected to the hepatic artery.
The HAI device pumps high doses of chemotherapy directly into the liver-- as much as 300 to 400 times higher than intravenous chemotherapy. The high doses of medication remain in the liver as opposed to circulating through the body as in traditional therapy.
Over time, tumors shrink or disappear. For patients who are not yet candidates for surgery to remove tumors, HAI can shrink tumors so they can be removed with surgery. For patients who have had liver tumors removed, HAI can reduce the risk of tumor recurrence.
The UChicago Medicine Comprehensive Cancer Center is one of a select number of hospitals in the nation that offers this advanced treatment. We're also leaders in hepatic artery infusion research, and are actively conducting clinical trials, with the goal of making HAI available to more patients who may benefit.
