Q&A with Dr. Rokita: Building bioinformatics infrastructure at the Brain Tumor Institute

Jo Lynne Rokita, PhD, is the director of the new Bioinformatics Core housed within the Brain Tumor Institute at Children’s National Hospital.

Jo Lynne Rokita, PhD, is the director of the new Bioinformatics Core housed within the Brain Tumor Institute at Children’s National Hospital. Dr. Rokita is a cancer genomics leader with 20 years of combined research experience in academia, industry and the government. She’s also a technical and analytical expert in genomics research using microarrays and high-throughput sequencing.

“We are very excited that we were able to recruit Dr. Rokita as director of the Bioinformatics Core Facility,” says Muller Fabbri, MD, PhD, associate center director for Cancer and Immunology Research at Children’s National. “Her Bioinformatics Core will play a central role in providing the Brain Tumor Institute community with unique expertise spanning biology/genetics/genomics and bioinformatics and will propel Children’s National forward as a national and worldwide leader in pediatric brain tumor research.”

Dr. Rokita is overseeing the core’s creation, including bringing both bioinformatics staff and computing infrastructure to the program, which will support the data analysis needs of the institute’s investigators. She recently answered questions about the new core and also talked a little bit about the focus of her own research that will continue at Children’s National.

Q: Why is the Brain Tumor Institute establishing a Bioinformatics Core?

A: Growing the institute’s bioinformatics capabilities was one of the things that leadership wanted to make sure was built into the plan for the record-setting $96 million gift that was received in 2023. There was a clear need among the principal investigators for this type of research support which includes organization, analysis and interpretation of large-scale genetic sequencing and other “-omics” data.

Q: How did you decide to join Children’s National?

A: I was leading a pediatric brain tumor focused bioinformatics team at Children’s Hospital of Philadelphia (CHOP). As a part of the Children’s Brain Tumor Network (CBTN), I worked closely with a collaborator from Children’s National, Brian Rood, MD, medical director of the Brain Tumor Institute. He told me about the opportunity and I was very excited to apply.

Q: How did your previous work prepare you for this role?

A: I’ve spent the past 10 years in the pediatric cancer field with the last six focused on brain tumor research. In my various roles at CHOP, I led multiple large-scale genomic analysis efforts, comprehensive data and methods for which we then provided openly to the community. During my postdoctoral fellowship, these efforts included a large neuroblastoma patient-derived cell line “ENCODE” as well as a resource led in collaboration with multiple institutes and the National Cancer Institute funded by Alex’s Lemonade Stand Foundation (ALSF). We further scaled these efforts to build open analytical platforms to empower researchers to build upon our work doing their own cancer genomic analysis. In collaboration with the Childhood Cancer Data Lab at ALSF, we built the platform that ultimately ballooned into the OpenPedCan includes large amounts of harmonized genomic, epigenomic and proteomic data for patients with pediatric cancer. What’s unique is that the data is all processed in the same way and easily accessible through multiple mechanisms. Researchers can use these data to ask questions about the cancer type they study or genes of interest. For example, genes over-expressed, absent and/or mutated in a specific tumor subtype may lead to a better understanding of how a patient’s cancer may respond to a treatment.

We’ll be bringing some of the workflows we created previously here to Children’s National, and that will allow us to join newly generated internal data with the thousands of data points we’ve already harmonized using these workflows.

Q: Can you give us some examples of how data harmonization benefits the field of pediatric brain tumor research?

A: Harmonizing across institutions and databases will help us increase the number of data points available for study. This is really important for rare types of tumors and are major foci of institute collaborator Adriana Fonseca, MD, and her International Rare Brain Tumor Registry program. The Bioinformatics Core will support data organization and analysis for this effort, which aims to sequence the rarest brain tumors — those that make up between only 3% and 5% of all brain tumors. If all the data is analyzed the same way, we can combine multiple studies to increase our total dataset, which in turn may reveal new biomarkers and new subtypes of those tumors. It is critical that we continue to build these data resources in a way that they can be accessed by everyone doing this work. Having dedicated support systems for these functions will push the research farther, faster.

Q: As this work gets underway, what is the core’s main function?

A: As this initiative gets underway, the Bioinformatics Core’s primary goal is to empower investigators by streamlining and centralizing data analyses. We help researchers transfer sequencing data into secure cloud storage, organize newly generated records and prepare those datasets for in-depth study. Our bioinformatics scientists then perform downstream analyses to address the specific questions posed by each investigator. On the backend, we collaborate with information technology at Children’s National to develop a robust infrastructure that supports these activities efficiently. By offering these services in-house, we aim to ensure our investigators have seamless, comprehensive support—ultimately driving innovation and accelerating research progress.

Q: What is “open science” and why is it important in bioinformatics?

A: One of our big focus areas is open science, meaning our goal is to push data and code out into the community so that researchers can easily reproduce and build upon our findings. I’m excited to bring the principles of open science, code sharing and data sharing to the Bioinformatics Core.

Making resources open makes it easier for teams to work together across institutions and research programs. It is also going to benefit patients because people can reuse the code and move towards cures faster. For example, we try to package an entire manuscript’s code when we provide our data so it’s clear how the analyses were done.

Q: What is your particular research passion?

A: I work in several research areas and with many brilliant collaborators. One of our focus areas is understanding how RNA splicing can contribute to pediatric brain tumors to create a change in a protein. We have recently identified tumor-specific splice events in some pediatric brain tumor types and will be partnering with Dalia Haydar, PharmD, PhD, to create therapeutic approaches to targeting these. We are also developing a user-friendly application for mining the large amount of splicing data in pediatric brain tumors.

Another focus of our lab is understanding how the patient’s host genome (alterations inherent in their blood DNA) influences the tumor’s genetics. For example, we’ve just preprinted a study connecting inherited variants to tumor genetics and patient outcomes.

Finally, we are interested in how differences in race, ethnicity and social determinants of health influence survival and treatment outcomes for children with brain tumors.

I am passionate about data sharing, code reproducibility and promoting open science in general.

Q: Is there any specific reason you decided to focus your work around brain tumors and pediatric brain tumors?

A: My cousin passed away from a brain tumor when I was in high school. They didn’t have molecular diagnosis then, but he had a brainstem glioma, likely a diffuse midline glioma. In graduate school, I studied addiction genetics and became fascinated with the brain and towards the end, cancer. As an alumna of Penn State, I was actively involved in philanthropic events raising money for their Dance MaraTHON supporting children with cancer. I was lucky to land a postdoc at CHOP and lean into subsequent roles which allowed my passion for this field to grow.

Q: Last question — What do you do with your time when you are not studying pediatric brain tumor data?

A: I enjoy being with my family, observing my children learn and grow, and listening to music.

AI team wins international competition to measure pediatric brain tumors

Winners of the International Conference on Medical Image Computing and Computer Assisted Intervention
Children’s National Hospital scientists won first place in a global competition to use artificial intelligence (AI) to analyze pediatric brain tumor volumes, demonstrating the team’s ground-breaking advances in imaging and machine learning.

During the International Conference on Medical Image Computing and Computer Assisted Intervention (MICCAI), the Children’s National team demonstrated the most accurate algorithm to study the volume of brain tumors – the most common solid tumors affecting children and adolescents and a leading cause of disease-related death at this young age. The technology could someday help oncologists understand the extent of a patient’s disease, quantify the efficacy of treatments and predict patient outcomes.

“The Brain Tumor Segmentation Challenge inspires leaders in medical imaging and deep learning to try to solve some of the most vexing problems facing radiologists, oncologists, computer engineers and data scientists,” said Marius George Linguraru, D.Phil., M.A., M.Sc., the Connor Family Professor in Research and Innovation and principal investigator in the Sheikh Zayed Institute for Pediatric Surgical Innovation. “I am honored that our team won, and I’m even more thrilled for our clinicians and their patients, who need us to keep moving forward to find new ways to treat pediatric brain tumors.”

Why we’re excited

With roughly 4,000 children diagnosed yearly, pediatric brain tumors are consistently the most common type of pediatric solid tumor, second only to leukemia in pediatric malignancies. At the urging of Linguraru and one of his peers at the Children’s Hospital of Philadelphia, pediatric data was included in the international competition for the first time, helping to ensure that children are represented in medical and technological advances.

The contest required participants to use data from multiple institutions and consortia to test competing methods fairly. The Children’s National team created a method to tap into the power of two types of imaging and machine learning: 3D convolutional neural network and 3D Vision Transformer-based deep learning models. They identified regions of the brain affected by tumors, made shrewd data-processing decisions driven by the team’s experience in AI for pediatric healthcare and achieved state-of-the-art results.

The competition drew 18 teams who are leaders from across the AI and machine learning community. The runner-up teams were from NVIDIA and the University of Electronic Science and Technology of China.

The big picture

“Children’s National has an all-star lineup, and I am thrilled to see our scientists recognized on an international stage,” said interim Executive Vice President and Chief Academic Officer Catherine Bollard, M.D., M.B.Ch.B., director of the Center for Cancer for Immunology Research. “As we work to attack brain tumors from multiple angles, we continue to show our exceptional ability to create new and better tools for diagnosing, imaging and treating these devastating tumors.”

During his presentation, he addressed attendees on the topic of the “Modern Management of Medulloblastoma,” discussing results of recently completed clinical trials and the implications of new molecular insights into medulloblastoma, the most common childhood malignant brain tumor.

In late November 2020,  Roger Packer, M.D., senior vice president of the Center for Neurosciences and Behavioral Medicine at Children’s National Hospital, presented as the inaugural keynote speaker for the First International Pakistan Neuro-Oncology Symposium in Karachi, Pakistan.

During his virtual presentation, he addressed attendees on the topic of the “Modern Management of Medulloblastoma,” discussing results of recently completed clinical trials and the implications of new molecular insights into medulloblastoma, the most common childhood malignant brain tumor.

The symposium attracted participants from 57 countries across the globe. There were over 1,000 attendees and as a result of the success of this symposium, there is now a monthly pediatric neuro-oncology lecture series. Dr. Packer agreed to lecture again to the group in mid-January 2021 on “Pediatric Neural Tumors Associated with NF1” as part of an international lecture series hosted by the Aga Khan University in Pakistan.

This is one of multiple national and international activities led by the Brain Tumor Institute at Children’s National Hospital. Directed by Dr. Packer with Eugene Hwang, M.D. as his co-director, and who is associate division chief of oncology at Children’s National Hospital, the multidisciplinary institute holds a monthly tumor board for colleagues at Dmitry Rogachev National Research Center and the Burdenko Neurosurgery Institute in Moscow, Russia, and a monthly brain tumor board coordinated by the Pediatric Oncology Program for colleagues across São Paulo, Brazil.

This also leads to a bi-monthly regional tumor board, which is attended by staff of the National Cancer Institute, the University of Virginia, Inova Children’s Hospital, the University of Maryland Children’s Hospital, Children’s Hospital of Richmond at VCU, Children’s Hospital of The King’s Daughters Health System, Yale University, Geisinger Medical Center, Georgetown University and Carilion Clinic.

A lifetime of achievements: Roger Packer, M.D.

Roger Packer with patient

Over the years, Dr. Packer and his team in Washington, D.C., have made meaningful contributions to children all around the world diagnosed with childhood brain tumors, including medulloblastoma and gliomas.

Earlier in December, Roger Packer, M.D., senior vice president of the Center for Neurosciences and Behavioral Medicine at Children’s National Hospital, received the 2020 Lifetime Achievement Award from the International Symposium on Pediatric Neuro-Oncology at the meeting organized in Karuizawa, Japan. The prestigious recognition is a testament to the years of commitment and dedication Dr. Packer has devoted to the care of children with brain tumors and as such, have placed him as a top leader.

This award is a recognition of how the field has grown since the first International Symposium on Pediatric Neuro-Oncology Dr. Packer organized in Seattle in 1989. “It grew from a small gathering of investigators to now a multidisciplinary group of over 2,000 investigators,” Dr. Packer says.

Over the years, Dr. Packer and his team in Washington, D.C., have made meaningful contributions to children all around the world diagnosed with childhood brain tumors, including medulloblastoma and gliomas. These findings have contributed to an increase of the survival rate from 50% to over 80% for children with medulloblastoma. In addition, his contributions have led to newer molecular targeted therapies and improved the quality of life of children who are long-term survivors.

“The field, especially in the last decade, rapidly transitioned to a more biologically informed field,” Dr. Packer explains. “We are now utilizing new, exciting discoveries in biology and genetics to inform new approaches to treatment. This kind of transition gives us great hope for the future.”

In his early career, Dr. Packer worked with two neuro-oncology patients who died and would impact his decision to further study this field. At that time, there was minimal understanding of the nature of neuro-oncology diseases or how to best treat them. As a neurologist, he was frustrated by the lack of understanding and as a pediatrician, he was frustrated at the lack of ability to do success management.

“I saw this as a gap in my personal knowledge and found that the field was struggling to come up with new answers and new approaches,” he says. “But at the same time other, advances were being made in child cancer care, such as with leukemia. However, there was no wide focus on pediatric brain tumors.”

Combining his knowledge of neurology with his curiosity and relying on other leaders that surrounded him in the same field, Dr. Packer worked on driving this new work forward. Today, he is still heavily involved in the development of treatment protocols that are increasingly transitional for a variety of brain tumors, including low-grade and high-grade gliomas.

“With the help of our great colleagues at Children’s National, we continue to try to develop new means to treat these tumors, including immunological approaches and the incorporation in the use of novel means, such as low-intensity and high-intensity focused ultrasound,” he says. “We also have an excellent multidisciplinary team at Children’s National that has grown over the last decade some of whom are acknowledged national leaders in the fields of brain tumors, clinical research and clinical care. We also have a robust program focusing on the neurocognitive outcome of children and ways to intervene to ameliorate intellectual compromise and improve quality of life.”

From discovery to ‘no excuses’ in neuro-oncology

For more than three decades, the world’s pre-eminent scientists and clinicians in pediatric neuro-oncology have convened the International Symposium on Pediatric Neuro-oncology every two years. Their goal is to advance the care and treatment of pediatric brain and central nervous system tumors by connecting across disciplines to share research findings and discuss the latest treatment approaches.

This year for the first time, representatives from parent advocacy groups and patient support foundations were also invited to attend the traditionally scientific meeting. Their inclusion allowed care providers and scientific investigators to make sure the voices of patients and families, and their needs, are heard.

Roger J. Packer, M.D., senior vice president of the Center for Neuroscience and Behavioral Medicine at Children’s National Health System, served as international organizing committee chair this year. He was chair and organizer of the very first symposium, held in 1986, and has led additional sessions over the years.

Dr. Packer had the honor of giving the opening keynote address to more than 1,200 participants in Denver this year. He used his lecture to highlight some of the amazing knowledge leaps made in the last decade in understanding the molecular makeup and genetics behind brain and spinal cord tumors.

“We’ve made more discoveries in these areas in the last 10 years than we made in the 50 years before that. It’s been a phenomenal decade for discovery,” he notes.  “But the fact remains we have not yet been able to translate all of this knowledge into more effective therapies for most children with brain and central nervous system cord tumors.”

Dr. Packer says progress made in managing and treating childhood low grade gliomas is one example of how care should move forward for other tumor types. The unique genetic and molecular makeup of low grade gliomas, which are the single most common form of childhood low grade tumor, has allowed clinicians to begin moving away from surgeries, radiation therapy and chemotherapy toward less neurotoxic treatments targeted at the specific molecular properties of the tumor itself.

“Although the chemotherapy protocol we began for low-grade gliomas 30 years ago works well and is still the standard of care today, the new molecular approaches we and others have tested will hopefully replace it soon and result in even better outcomes,” he adds.

Medulloblastoma, the most common form of malignant brain tumor, is one area Dr. Packer notes could stand to benefit from therapies with less impact on a child’s quality of life. The current treatment protocol used for this childhood tumor also remains the same as the one that Dr. Packer helped develop more than 30 years ago.

“Our protocol is effective, and we’ve moved survival from 50 percent to 80 percent for these types of tumors using this approach, but it’s time to determine how best to move toward effective molecularly targeted therapies that would allow us to reduce the neurotoxic treatments necessary to treat these tumors.”

“We have to move from our decade of discovery to a decade of no excuses where we are able to use what we’ve learned to improve the care of all childhood brain and spinal cord tumors,” he says.

Dr. Packer says the key is to avoid getting paralyzed by the mountain of molecular data that is available and really focus on the specific information needed to make treatments more precise.

One promising new approach is the use of immunotherapy for pediatric brain and spinal cord tumors. Children’s National and colleagues from across the U.S. are at the forefront of developing these therapies to control tumor growth, and presented several related studies at ISPNO:

  • Eugene Hwang, M.D. presented the findings from immunotherapy clinical trials for brain and central nervous system tumors, including diffuse intrinsic pontine glioma (DIPG).
  • Karin Walsh, Psy.D., shared new data demonstrating the reduced neurotoxicity of a new molecularly targeted agent.

There were also several poster session presentations where Dr. Hwang, Lindsey Kilburn, M.D., Brian Rood, M.D., and others from the Children’s National team shared findings related to the potential and the challenges of molecular targeted therapies, especially immunotherapies. The team at Children’s also presented data related to new findings about how to reverse neurologic and neurocognitive deficits that often result from these conditions, including some that for years were thought to be irreversible, such as vision deficits.

Dr. Packer notes that many of the newest clinical trials both in the U.S. and internationally have the potential to kick start this decade of “no excuses.”

“We’ve made great progress, but we haven’t yet been able to take full advantage of the knowledge we’ve amassed. To do it, we all have to work together as a community nationally and internationally to change the paradigms of how we treat these children and make meaningful advances.”

New guidelines advance treatment approach for children with low-grade gliomas

Roger Packer examines a patient

“We believe our understanding of LGGs combined with novel therapies will soon lead to a new standard of care for children,” says Roger J. Packer, M.D. “We are optimistic about the future for patients with this disease.”

Patients with low-grade gliomas (LGGs) will benefit from new recommendations from a group led by Roger J. Packer, M.D., senior vice president for the Center for Neuroscience and Behavioral Medicine, as well as clinicians, researchers and industry leaders from around the world, that were recently published in Neuro-Oncology. The new framework for LGGs will significantly advance the future of care for patients with these complex diseases and set a new path to expedite the translation of scientific advances into clinical care. The recommendations build on a treatment approach developed more than 25 years ago by Dr. Packer and his colleagues that revolutionized care for LGGs.

LGGs are both common and complicated, and one treatment approach does not work for all cases. Until now, there has not been a standardized way to categories the tumors to prescribe more effective and personalized treatment options. The new guidelines will provide clinicians with one mutually agreed upon set of recommendations to further advance the field and better diagnose and treat patients with LGGs.

Topics within the framework include:

  • Implications of the growing understanding of genomics underlying these tumors and how to apply to clinical practice
  • The need for more and better model systems to assess the likely benefits of new treatments for LGGs before exposing patients to new therapy
