Oncology Referrals
At the Hyundai Cancer Institute at CHOC, we have a comprehensive, multidisciplinary team of experts addressing Histiocytic syndromes such as Langerhans Cell Histiocytosis (LCH) and immune dysfunction problems leading to Hemophagocytic Lymphohistiocytosis (HLH). LCH may be caused by abnormal mutation in a tumor that leads to production of abnormal cells that cluster together and can attack the skin, bones, lung, liver, spleen, gums, ears, eyes and/or the central nervous system. In some cases, the disease is limited to one area of the body and spontaneously regresses and in other cases, histiocytosis spreads to many organs and can be chronic and debilitating.
At CHOC, we are participating in both international and national clinical trials and offer innovative targeted therapies, immunotherapy as well as a robust blood at marrow transplant program. The Histiocytosis Treatment Program at CHOC has brought together leaders in this field. In fact, the Hyundai Cancer Institute is one of the top histiocytosis referral centers in the Southwest. When a patient cannot travel to us, our experts frequently advise and collaborate with physicians at other institutions. Our multidisciplinary team prides itself on keeping up on the latest trends in treatment by presenting their findings on histiocytosis at international conferences.
What We Treat
According to the Histiocyte Society, most people diagnosed with histiocytosis are children under the age of 10. Our specialists treat all forms of histiocytosis including but not limited to:
- Langerhans cell histiocytosis (LCH)
- Hemophagocytic lymphohistiocytosis (HLH)
- Juvenile Xanthogranuloma (JXG)
- Rosai Dorfman Disease
Clinical Trials and Research
Two months after their son Ricky was born on Dec. 6, 2012, Richard Alcedo and his wife, Wendy, noticed he was getting small bumps on his face. They took Ricky to several doctors until a dermatologist did a skin test and diagnosed him with JXG (juvenile xanthogranuloma), a type of histiocytosis. JXG is an extremely rare disease that even in its common form affects only one in 1 million children, typically those 10 or younger. Tests confirmed that Ricky not only had JXG, but systemic JXG—a rare form of the disease that afflicts only one in 10 million children.
Dr. Lilibeth Torno is one of 10 physicians at the Cancer Institute who are immersed in such cutting-edge research as molecular and genetic profiling to find out what triggers such diseases as LCH, JXG or HLH—and what can be done to cure them. The histiocytosis experts at the Hyundai Cancer Institute are leaders in the treatment of histiocytosis with access to early-stage clinical trials and the latest research on treatments.
Frequently Asked Questions about Histiocytosis Treatment
We understand that a histiocytosis diagnosis is overwhelming. To make the treatment process a little less confusing, the Histiocytosis Team has put together a list of frequently asked questions and answers to make the process a little easier to discuss with family and friends. The information should not replace that provided by the child’s health care team.
How long does it take to get biopsy results?
Pathology results take at least three business days from the biopsy date. If pathology is difficult then it might be sent to another facility, which can take up to another week for their final diagnosis.
Does my child need a blood or marrow transplant (BMT)?
A bone marrow transplant is not the first line of therapy with histiocytosis. Extreme cases of histiocytosis may be treated with an allogenic bone marrow transplant.
Should my child not leave the house while receiving chemotherapy?
Children on chemotherapy do not need to stay in the house. It is good for them to go outside and get fresh air. Just remember to use sunscreen and hats because chemotherapy can make the patient’s skin sensitive. It is also important for the child to wear a mask when in crowded public places or when coming to and from the clinic or hospital. Learn more about the precautions to take while undergoing chemotherapy.
Should my child be on a strict diet?
Patients on chemotherapy do not need to be on a strict diet; a normal, well-balanced diet is recommended. Patients should avoid eating rare foods like sushi and rare meats. Fruits and vegetables should be wash and caregivers should carefully watch expiration dates on food items.
Do I have to get rid of the family dog or other pets?
There is no need to get rid of the family pet unless it is a reptile or a bird. Because reptiles and birds may carry salmonella, we recommend having another family member or friend take care of the pet while the patient is on chemotherapy. Children receiving chemotherapy should not clean up after or feed any family pet. We also do not recommend getting a new dog or pet while the patient is receiving treatment.
What will I have to do when treatment is done?
After treatment is completed, the patient will come to clinic every month for a doctor’s visit for the first year off therapy. Scans will be done every three months for the first year off therapy.
