The Center for Cancer and Blood Diseases at Lucile Packard Children's
Hospital at Stanford has world-renowned research programs dedicated to
developing new treatments for cancers and blood diseases that affect
children.
Our physicians and researchers hold leadership roles in the
Children's Oncology Group (COG). The Children's Oncology Group is a
national clinical research consortium made up of more than 200 pediatric
cancer centers, which designs and evaluates cancer therapies through
large clinical trials. Because we are a participating Center, all of our
patients are eligible for treatment protocols used by this respected
national research cooperative. Clinical trials allow our patients access
to promising treatments still in development. The Center has an average
of 75 active clinical trials available to eligible patients.
Our clinical research includes Phase I, II and III clinical trials
investigating experimental therapies and new agents that reduce toxicity
of chemotherapies. Our team also works closely with researchers at the
Stanford School of Medicine in genetic profiling of tumors, new drug
development and genetic targets for therapies.
Some of our clinical research highlights include:
Leukemia
Investigators at Lucile Packard Children's Hospital have been leaders in
dissecting the immunology of acute lymphoblastic leukemia and in
discerning the molecular events which underlie leukemogenesis. Packard
investigators are nationally recognized for studies directed at
reversing multi-drug resistance in leukemia and applying these findings
to the treatment of children with refractory leukemia and more recently
to the treatment of children with newly diagnosed acute non-lymphocytic
leukemia.
Late Effects/Long Term Survivorship
The pediatric group at Lucile Packard Children's Hospital is part of a
national study of 25,000 survivors of childhood cancer and place special
emphasis on the assessment of cardiac, pulmonary and neurocognitive late
effects.
Gene Therapy for Hemophilia
Researchers at Lucile Packard Children's Hospital and Stanford
University Medical Center are testing a novel new treatment for
hemophilia B. Patients with hemophilia B lack the ability to produce
enough of a protein - called factor IX - essential for successful blood
clotting. The researchers, led by Mark Kay, MD, PhD and Bertil Glader,
MD, PhD, have genetically modified a virus to produce factor IX. In two
of the three adult patients who participated in a small-scale study, the
injected virus made enough factor IX to reduce the patients' dependence
on external administration of the factor to treat bleeding episodes.
Kay and his colleagues are continuing their research into the gene
therapy of hemophilia. They would also like to use the approach to treat
the more common version of hemophilia, hemophilia A.
Non-Myeloablative Transplants
Our team is participating in some of the early clinical trials for a
promising new treatment called non-myleoablative hematopoietic stem cell
transplants.
Although researchers and clinicians have made much progress in improving
the outcomes of hematopoietic stem cell transplants, the risk of
developing complications after an allogeneic transplant (a transplant
using bone marrow or peripheral blood stem cells provided by a donor) is
still substantial.
The goal of a non-myeloablative allogeneic hematopoietic stem cell
transplantation is to offer the benefit of a standard transplant, but
with reduced toxicity. In a standard transplant procedure, a child
undergoes very high dose chemotherapy -- with or without radiation
therapy -- to destroy as many cancer cells as possible before the
healthy donor stem cells are transplanted into the patient.
Because the treatment also destroys the patient's bone marrow and immune
system, the donor's stem cells are not rejected, and grow to replace the
patient's bone marrow. A non-myeloablative transplant uses much smaller
and less toxic doses of chemotherapy and radiation, allowing the stem
cells of both the patient and the donor to coexist (a condition known as
immune tolerance). This partial replacement of the bone marrow function
can cure many diseases while reducing the severity of treatment side
effects.
Relapse After Transplant
Relapse remains a significant threat following a bone marrow transplant
for leukemia. Our physicians are looking for alternative treatment
approaches to further reduce the risk of relapse. One option they are
researching is the use of leukocyte, or white blood cell, infusions to
encourage the new bone marrow to graft and then attack the leukemia
cells. Another study is investigating the use of a novel pre-transplant
therapy prior to the transplant, which will attack and weaken the
leukemia cells.
Our doctors are also developing new ways to process bone marrow in the
laboratory to make it more acceptable to the recipient. This will allow
doctors to broaden the availability of appropriate donors.
Graft-Versus-Host Disease
Graft-versus-host disease (GVHD) is a condition that occurs when the
newly regenerated immune system arising from an allogeneic transplant
attacks the patient's body and damages organs and tissues. The drugs
that a recipient of an allogeneic transplant takes to suppress their
immune system and reduce the chance of developing GVHD also make them
susceptible to developing a serious infection. Lucile Packard Children's
Hospital physicians are working on new drugs to diminish the risk of
GVHD following hematopoietic stem cell transplant while minimizing the
risk of infection.
Lucile Packard Children's Hospital is located in Palo Alto, adjacent to Stanford University Hospital, approximately 20 miles north of San Jose, CA and 40 miles south of San Francisco.
