Hematology

As Chief of the Hematology Service at Memorial Sloan Kettering Cancer Center (MSK), I lead a team of hematologists that sees approximately 4,040 patients with benign blood disorders each year.

At MSK, my fellow hematologists and I collaborate to deliver personalized cancer care that considers each patient’s needs and preferences. When I meet with patients, I don’t just treat them as if they were my own family members — I try to put myself in their shoes.

Often, patients are concerned about the blood-related complications that can occur with cancer treatment. Some of the most common questions that patients ask me relate to the likelihood of experiencing blood-related complications on a medication, other possible side effects, and how long they need to be on a specific therapy. I take the time to clearly explain what patients can expect and address the concerns related to their condition. No matter the diagnosis, there is world-class expertise at MSK.

In patients with cancer, blood-related disorders, such as blood clots, low blood counts including anemia, and bleeding disorders, which may require special attention, regardless of whether the disorder is pre-existing, or a side effect of cancer treatment. Patients who already had a blood disorder before they were diagnosed with cancer might tailored therapies.

Sometimes, patients receiving cancer therapy will experience blood-related side effects. These can include blood clots that form in a deep vein (deep vein thrombosis [DVT]) or decreases in the number of platelets in the blood (thrombocytopenia). Cancer-associated thrombosis is a condition that can develop when someone is undergoing treatment for cancer. Beyond caring for existing blood-related disorders, the Hematology Service also provides prompt medical attention to address any blood-related side effects, including thrombosis.

In addition to caring for patients with benign blood disorders, I study cancer-associated thrombosis to better understand its risk factors and develop novel treatment approaches. To date, I have led several National Institutes of Health-funded studies in cancer-associated thrombosis. I currently serve as the Chair of the International Society on Thrombosis and Haemostasis. Inc.’s (ISTH) subcommittee on hemostasis and thrombosis. I also previously acted as the Vice-Chair and Chair of the American Society of Hematology’s subcommittee on thrombosis and vascular biology. Through research and leadership in national and international professional organizations dedicated to thrombosis, I hope to improve the prevention and treatment of cancer-associated thrombosis.
