I am a pediatric hematologic oncologist on the MSK Kids team who cares for infants, children, and young adults with cancer. In my research, I study the biology of leukemia, lymphoma, and Wilms’ tumor, as well as develop therapies that improve the long-term survival of people with these cancers.
For more than 40 years here at Memorial Sloan Kettering, I have directed the treatment of children and adolescents with leukemia. During this time, my colleagues and I developed new treatment protocols for leukemia, including the New York I and New York II protocols. These are now used as the standard of care all over the world. These treatment regimens have improved the survival of people with acute lymphoblastic leukemia (ALL), the most common cancer in children, from 50 percent in the 1970s to more than 80 percent for high-risk patients and more than 90 percent for standard-risk patients today.
We have also studied new drugs and new combinations of drugs in people with leukemia that has become resistant to standard therapies, and we have improved the survival of these children and young adults. We are continuing our research to develop more-effective therapies for pediatric leukemia that returns after initial treatment.
I have been a member of the Leukemia Strategy Group of the Children’s Oncology Group for more than 20 years. I have chaired or co-chaired 11 large national and international studies for the group and have been a committee member of many other investigations. These research studies evaluate different treatments, including investigational therapies, for young patients with leukemia, lymphoma, or other cancers. I am a member of the National Comprehensive Cancer Network committee that develops national guidelines for the treatment of children with ALL. I recently stepped down from my role as a principal investigator of the Children’s Oncology Group, a position that I was privileged to have since the group’s inception.
At Memorial Sloan Kettering, we have state-of-the-art therapies for the cancers and cancer-related problems that are most frequently seen in young patients. But we also care for children with unusual tumors or cancer-related illnesses. We treat each child or young adult as an individual. When necessary, we create tailor-made therapies to meet their unique needs. Instead of trying to fit a patient to a therapy, we make the therapy fit the patient. We do everything we can to help our patients get better.
MSK Kids was also among the first to recognize the stress that cancer and its treatment can have on children and their families. We have observed the long-term physical and emotional effects of cancer therapy in young patients. For many years, we have taken steps to minimize these effects. There is nothing more rewarding than seeing one of my patients finish therapy and return to their normal activities, with no negative memories of the treatment process. I love to go to their happy life events, such as bar mitzvahs and weddings, and to watch their own children grow.
Doctors at Memorial Sloan Kettering work as teams, with specialists from all different areas. This allows us to consider all your needs together, and to give you the best possible care.
