From November 16 to 19, medical professionals, clinicians, nurses and oncology patients and families from around the globe gathered for the International Society of Paediatric Oncology (SIOP) in Kyoto, Japan. Pediatric experts in their respective fields Jeffrey Dome, M.D., Ph.D., AeRang Kim, M.D., Ph.D., Steven Hardy, Ph.D., and Karun Sharma, M.D., attended SIOP representing Children’s National. The four-day scientific programme engaged those in pediatric oncology with educational lectures, keynote speakers, tailored sessions for survivors, families and support organizations, free paper sessions, specialist sessions and Meet the Expert talks.

Dr. Kim, an oncologist with the Center for Cancer and Blood Disorders and a member of the solid tumor faculty at Children’s National, presented with Dr. Sharma, director of Interventional Radiology at Children’s, on “Interventional Radiology: Technology and Opportunities” in Meet the Expert talks on both Saturday and Sunday of the programme. They discussed background information, preclinical studies, current, ongoing studies of high-intensity focused ultrasound (HIFU), HIFU in combination with heat sensitive formulated chemotherapy and future directions. In 2017, Children’s National was the first U.S. children’s hospital to successfully use MR-HIFU to treat osteoid osteoma, and is currently accruing on early phase studies evaluating HIFU ablation and HIFU in combination with lyso-thermosensitive liposomal doxorubicin for pediatric patients with refractory/recurrent solid tumors.

Dr. Hardy, a pediatric psychologist in the Center for Cancer and Blood Disorders at Children’s, presented on “Brief Psychosocial Screening to Identify Patients in Need of a Mental Health Treatment Referral in a Childhood Cancer Survivorship Clinic.” In his educational lecture, Dr. Hardy described findings that show a brief mental and behavioral health questionnaire given to patients in the Children’s National survivorship clinic is a sensitive screening tool that can identify patients in need of more formal psychosocial evaluation and treatment. He also presented data supporting the use of a lower threshold of psychological symptoms necessary to trigger discussions about mental health treatment compared to previous reports. The key implication of Dr. Hardy’s work is that survivorship clinics lacking embedded psychology support could adopt this questionnaire, which is publically available and translated into 86 languages, to help identify survivors with mental and behavioral health concerns and ensure appropriate referrals are made.

Dr. Dome, Vice President of the Center for Cancer and Blood Disorders, served on the SIOP Scientific Programme Advisory Committee, which selected the topics for presentation.

SIOP provides an international forum for the sharing of new research and ideas related to pediatric oncology. The annual conference furthers the efforts made towards developing new treatments and cures and opens the conversation, encouraging innovation and collaboration with experts from around the world. Children’s National has taken part in SIOP for many years, most recently hosting the meeting in Washington, D.C., in 2017.

Osteoid osteoma successfully treated with MR-HIFU

Karun Sharma

Doctors from the Sheik Zayed Institute for Pediatric Surgical Innovation at Children’s National Health System have completed a clinical trial that demonstrates how osteoid osteoma, a benign but painful bone tumor that commonly occurs in children and young adults, can be safely and successfully treated using an incisionless surgery method called magnetic resonance-guided high-intensity focused ultrasound (MR-HIFU).

Published in The Journal of Pediatrics on Aug. 17, 2017, the study compares nine patients, ages 6 to 16 years old, who were treated for osteoid osteoma using MR-HIFU with a nine-patient historical control group, ages 6 to 10 years old, who were treated at Children’s National using radiofrequency ablation (RFA) surgery, the standard treatment at most U.S. hospitals. The study results show that treatment using MR-HIFU is feasible and safe for patients, eliminating the incisions or exposure to ionizing radiation that is associated with the RFA procedure. Children’s National is the first U.S. children’s hospital to successfully use MR-HIFU to treat osteoid osteoma.

CT-guided RFA, the most commonly used osteoid osteoma treatment, requires drilling through muscle and soft tissue into bone and also exposes the patient and operator to radiation from the imaging necessary to guide the probe that is inserted to heat and destroy tumor tissue.

“Our objective is to provide a noninvasive treatment option for children with osteoid osteoma and we’re very pleased with the results of this clinical trial,” says Karun Sharma, M.D., Ph.D., director of Interventional Radiology at Children’s National and principal investigator for the osteoid osteoma trial. “We have now shown that MR-HIFU can be performed safely with clinical improvement that is comparable to RFA, but without any incisions or ionizing radiation exposure to children.”

High-intensity focused ultrasound therapy uses focused sound wave energy to heat and destroy the targeted tumor under MRI guidance. This precise and controlled method does not require a scalpel or needle, greatly reducing the risk of complications like infections and bone fractures. It is also a faster treatment option, with expected total procedure time of 90 minutes or less. In the U.S., MR-HIFU is used to treat uterine fibroids and painful bone metastases from several types of cancer in adults, but has not previously been used in children.

This breakthrough is the latest from the Image-Guided Non-Invasive Therapeutic Energy (IGNITE) program, a collaboration of the Sheikh Zayed Institute and the departments of RadiologyOncologySurgery, and Anesthesiology at Children’s National. The goal of the IGNITE program is to improve the quality of life and outcomes for pediatric patients through the development and clinical introduction of novel minimally invasive and noninvasive surgery technologies and combination therapy approaches. The team is led by Peter Kim, M.D., Ph.D., vice president of the Sheikh Zayed Institute.

“The use of MR-HIFU ablation of osteoid osteoma is a perfect example of our mission in the Sheikh Zayed Institute to make pediatric surgery more precise, less invasive and pain-free,” says Dr. Kim. “Our leading team of experts are also exploring the use of MR-HIFU as a noninvasive technique of ablating growth plates and pediatric solid tumors. We also have another clinical trial open for children and young adults with refractory soft tissue tumors, which is being performed in collaboration with Dr. Bradford Wood’s team at the National Institutes of Health, and if successful, it would be the first in the world.”

In addition to Drs. Sharma and Kim, the Children’s National team for the ablation of osteoid osteoma clinical trial included: AeRang Kim, M.D., Ph.D., pediatric oncologist; Matthew Oetgen, M.D., division chief of Orthopaedic Surgery and Sports Medicine; Anilawan Smitthimedhin, M.D., radiology research fellow; Pavel Yarmolenko, Ph.D., Haydar Celik, Ph.D., and Avinash Eranki, engineers; and Janish Patel, M.D., and Domiciano Santos, M.D., pediatric anesthesiologists. Ari Partanen, Ph.D., a senior clinical scientist from Philips, was also a member.

Doctors from the Sheikh Zayed Institute for Pediatric Surgical Innovation and surgeons from Children’s National are the first in the U.S. to use Magnetic Resonance-Guided High-intensity Focused Ultrasound (MR-HIFU) to treat pediatric osteoid osteoma.

The trial, led by Principal Investigator Karun Sharma, M.D., Ph.D., Director of Interventional Radiology at Children’s National, began in 2015 and is demonstrating early success in establishing the safety and feasibility of noninvasive MR-HIFU as an alternative to the current, more invasive approaches to remove tumor tissue.

Osteoid osteoma is a painful, but benign, bone tumor that commonly occurs in children and young adults. Removal generally requires orthopaedic surgery to scrape the tumor from the bone or CT (computerized tomography) image-guided radiofrequency ablation (RFA), which is less invasive than surgery but is associated with ionizing radiation exposure and requires drilling through muscle and soft tissue into bone.

MR-HIFU, on the other hand, is a precise and controlled method that does not require a scalpel or needle, greatly reducing the risk of complications, including infections and bone fractures. Even better, it promises reduced procedure time, typically an hour or less.

“Our team set out to provide a noninvasive and radiation free treatment option for children with osteoid osteoma and our pilot feasibility and safety trial is almost completed. We have treated 9 patients and we’re very pleased with the success of the treatments so far. Although follow up will continue for another year, results to date that show that MR-HIFU may be a completely non-invasive and radiation free treatment for osteoid osteoma,” Dr. Sharma says. “Several of the children we treated were very active prior to the onset of their tumor, one a soccer player and the other a swimmer, but because of pain from the tumor, they were unable to enjoy their favorite activities, until now.”

“The use of MR-HIFU ablation of osteoid osteoma is a perfect example of our mission in the Sheikh Zayed Institute to make pediatric surgery more precise and less invasive,” adds Peter Kim, M.D., C.M., Ph.D., Vice President of the Sheikh Zayed Institute, who leads the Image Guided Non-Invasive Therapeutic Energy (IGNITE) program.

IGNITE is a joint clinical and research collaboration between the Sheikh Zayed Institute and the Divisions of Radiology, Oncology, Surgery, and Anesthesiology at Children’s National. MR-HIFU is also being used to treat pediatric refractory soft tissue tumors, a first-in-the-world clinical trial that is a collaboration between Children’s National and the NIH Center for Interventional Oncology directed by Bradford Wood, MD. Additionally, the IGNITE team has started preliminary work to explore applications of MR-HIFU for noninvasive ablation of growth plates and pediatric solid tumors.

In addition to Drs. Sharma and Kim, the team for the ablation of osteoid osteoma clinical trial includes: AeRang Kim, MD, PhD, pediatric oncologist; Matthew Oetgen, M.D., Division Chief of Orthopaedic Surgery and Sports Medicine; Kaleb Friend, M.D., pediatric orthopedic surgeon; Pavel Yarmolenko, Ph.D., Haydar Celik, Ph.D., and Avinash Eranki, biomedical engineers; Viktoriya Beskin, MR technologist; and Janish Patel, M.D., and Domiciano Santos, M.D., pediatric anesthesiologists.
