TWiPO #25 ~ Histones in Pediatric Gliomas
April 05, 2012
Host Dr Tim Cripe welcomes back co-host Dr Lionel Chow to discuss somatic mutations in pediatric brain tumors. After recapping the consensus paper on molecular subgroups in medulloblastoma discussed in TWiPO episode 22 (Brain Tumor Round Robin) Dr Chow highlights the significance of the driver mutations in histone H3.3 in pediatric glioblastoma. Results of whole exome sequencing have shown that significantly more somatic mutations are present in adult tumors compared to pediatric tumors. This difference might suggest a reason for better success rates in pediatric tumors and possibly more escape mechanisms in adult tumors. Dr Chow also discusses a paper published by the Pediatric Cancer Genome Project (a St. Jude Children's Research Hospital–Washington University collaboration) on somatic histone H3 alterations in diffuse intrinsic pontine glioma (DIPG). The findings are significant in showing that this mutation is present in 36% of non-brain stem gliomas and in 78% of brain stem gliomas, but in none of the other pediatric tumor types.

TWiPO #24 ~ Cord Blood Banking: Interview with Machi Scaradavou
March 06, 2012
Dr Tim Cripe welcomes Dr Andy Kolb from AI DuPont in this episode of TWiPO, and special guest Dr Andromachi Scaradavou, the Medical Director of New York Blood Center's National Cord Blood Program.
NYBC is the world's oldest and largest public cord blood bank, and collects, processes, tests and stores cord blood that mothers donate shortly after birth. The cord blood is for children and adults with no related donor available who need a hematopoietic stem cell transplant for life-threatening illnesses. More than 60,000 units are stored at NYBC and more than 4500 units have been provided for transplants worldwide. The variety of ethic groups represented is much higher in cord blood banking than in bone marrow donor programs. The percentage of use is climbing significantly for pediatric transplants partly because of the small dose required.
Discussants cover many aspects of this fascinating subject: background and uses of cord blood, logistics of collecting, processing, storing, and selecting units for transplants, as well as the advantages and challenges currently faced in this field.

She describes her experience with polio, paralysis from the neck down, crutches for mobility, and later, her confinement to a wheelchair. Revealing another era in communications with parents and patients in the 1960s and 1970s, she explains how parents were advised to use the term "anemia" to describe their child's condition rather than "leukemia" to to explain why the child would require periodic blood transfusions, in order to prevent shunning by friends and family. Dr Lampkin also shares her satisfaction in following the earliest survivors of pediatric cancer she treated who are now in their 40s and 50s.
TWiPO #20 ~ The F-word in Pediatric Cancer Research
November 15, 2011
Today’s episode features an impressive lineup for a hot topic. Host Dr Tim Cripe warns: “If your blood isn’t boiling by the end, you weren't listening.” Hear Tim and co-host Dr Lionel Chow discuss pediatric cancer research funding with guests Dr C. Patrick (Pat) Reynolds, Dr E. Anders (Andy) Kolb, and parent Joe McDonough.
Dr Pat Reynolds puts government spending on the number one disease killer of children in the US in perspective, comparing the tiny $200M spent on pediatric cancer research to the foreign aid budget of $22B (less than 1%). For example, $1.6B goes to Egypt alone. The COG budget is a mere $46M. The DOD budget is $700B. See his slides here. Dr Lionel Chow mentions an enlightening fact – private donations to St Jude exceed $600M per year, on top of the givers’ paying taxes. This is 3 times the entire NCI budget for pediatric cancer research for all institutions in the US.
Spending per Person Years Life Lost is compared for childhood cancers and adult cancers, see graph here.
Dr C Patrick Reynolds is Director, Cancer Center and Professor of Cell Biology & Biochemistry, Internal Medicine, and Pediatrics, School of Medicine, Texas Tech University Health Sciences Center, Lubbock TX. Dr E Anders Kolb is the Director of Blood and Bone Marrow Transplantation at Alfred I. duPont Hospital for Children, and Head of the Cancer Therapeutics Laboratory at Nemours Biomedical Research, Wilmington, DE. Joe McDonough is father to Andrew, and founder of The Andrew McDonough B+ (Be Positive) Foundation, raising money for families and research.

23:00 min. Recent findings from the TARGET Initiative (Therapeutically Applicable Research to Generate Effective Treatments) http://target.
Through NIH's TARGET initiative, scientists sequenced 120 candidate genes in 187 high-risk childhood B-precursor acute lymphoblastic leukemias (HR B-ALL) and normal tissues and combined the results with data from previous studies using microarry and gene copy number studies. Sorting through this massive amount of information revealed a high frequency of recurrent genetic alterations in several specific cancer signaling pathways. The information appears to be useful to stratify these patients into subcategories, some of whom do much better than others. These data highlight potential new therapeutic targets in certain subsets of childhood ALL.

TWiPO #11 ~ BuMel SIOP results and MIBG transplant with Dr Brian Weiss
July 12, 2011
In this eleventh episode of "This Week in Pediatric Oncology" hosts Dr Tim Cripe and Dr Lars Wagner discuss with guest Dr Brian Weiss (Cincinnati Children's Hospital) the implications of the recent results comparing two chemotherapy combinations for transplant regimens in children with high-risk neuroblastoma in Europe. The BuMel (busulfan, melphalan) regimen resulted in better survival and lower toxicity than CEM (carboplatin, etoposide, melphalan), a regimen used for transplant in the COG for a decade.
This SIOP trial was one of the plenary presentations at ASCO in June 2011. In this lively and informative discussion, Dr Brian Weiss explains the COG response to these results due to the difference in induction regimens. The BuMel regimen will be used in the upcoming MIBG frontline pilot that Dr Weiss is leading as principal investigator.
Dr Weiss and TWiPO hosts also discussed the recent paper Safety and efficacy of tandem (131) I-metaiodobenzylguanidine infusions in relapsed/refractory neuroblastoma authored by Johnson et al in Pediatr Blood Cancer. 2011 Apr 14

TWiPO #10 ~ Interview with Dr Robert Seeger
July 07, 2011
"This Week in Pediatric Oncology" podcast host Dr Tim Cripe interviewed Dr Robert Seeger from CHLA (Children's Hospital of Los Angeles) about his contributions to improvements in treating neuroblastoma as well as his vision for future advances.
Dr Seeger's career has been remarkable in that he began with an interest in immunotherapy and neuroblastoma as an intriguing model for this approach, and has consequently been involved in every major advance in treating neuroblastoma, including the pivotal 1984 discovery of the first-ever amplification of an oncogene for any cancer – MYCN and the 1985 demonstration that MCYN could be used to predict survival. Authoring over 180 publications, Dr Seeger has made a significant contribution to every step toward developing better therapies for neuroblastoma, including induction therapy, myeloablative therapy, immunotherapy with anti-GD2 antibody and cytokines, maintenance therapy with retinoids, and most recently, work in tumor microenvironment and developing reproducible biomarkers for detecting minimal residual disease. At the beginning of Dr Seeger’s career, survival for high-risk neuroblastoma was abysmal at about 5%, and now survival is about 45%. Dr Seeger has been a leader in the NANT consortium (New Approaches to Neuroblastoma Therapy) and involved in planning the early phase clinical trials conducted by this 15-member consortium.
When questioned about current challenges in his research, Dr Seeger mentioned the increased regulatory burdens associated with developing new treatments, and also discussed the need for preclinical (mouse) models that are predictive and well-validated. Dr Seeger believes that improvements can be made in functional imaging, including developing pharmacodynamic markers to detect impact of therapy on tumor.
Dr Seeger is Professor and Division Head for Basic and Translational Research at Children's Center for Cancer and Blood Diseases, Children's Hospital Los Angeles/USC School of Medicine in Los Angeles, CA. His research interests are neuroblastoma risk assessment by gene expression profiling at diagnosis; evaluating response to treatment by quantifying rare neuroblastoma cells in blood and bone marrow; immunotherapy of neuroblastoma (natural killer cells, anti-tumor antibodies, tumor associated macrophages). Dr Seeger is a reviewer for several high-impact oncology journals, and is a member of the COG NB steering committee. He earned his MD at Oregon Health Sciences University School of Medicine in Portland and completed pediatric internship and residency at the University of Minnesota Medical School in Minneapolis. Additionally, Dr Seeger obtained research fellowship training at the National Cancer Institute (NCI) and the ICRF Tumor Immunology Unit at University College London, UK.

TWiPO #9 ~ Interview with Dr Peter Adamson
June 16, 2011
Host Dr Tim Cripe of "This Week in Pediatric Oncology" podcast interviews Dr Peter Adamson, new Chair of the Children's Oncology Group (COG). Co-hosts for this episode are Dr Jim Geller, Dr Raj Nagarajan, and Dr Lionel Chow. This conversation includes Dr Adamson's background and interest in pediatric oncology, and openly addresses the much-needed advances in drug development for pediatric tumors that are distinct from adult tumors. On the heels of the remarkable ch14.18 development story in neuroblastoma, Dr Adamson explains the need for a "virtual" drug company that consists of a public-private partnership to develop drugs in a similar narrow venue, which is underway.
