Podcast Description
Sponsored by Solving Kids' Cancer. Purpose: To communicate, discuss, debate and interpret the latest advances and controversies in treating childhood cancers. Improved understanding by professional stakeholders of new findings including their nuances and limitations will help further advance both clinical care and research by producing transparency, minimizing misunderstandings and misinterpretations, and identifying knowledge gaps. Intended audience: The podcast will primarily be of interest to professionals including scientists, health care providers (physicians, physician assistants, nurses) and students at all levels of training. The topics will also appeal to lay audiences who seek high-level (expert) information on pediatric cancers. Forum: A weekly audio recording of an informal, conversational discussion of two recent publications on any aspects of childhood cancer, from basic science and diagnostics to therapeutics and survivorship. Findings presented at meetings (ASPHO, AACR, ASCO, ASH) may also be discussed. We may also mention ongoing clinical trials. Any email questions or comments from listeners sent in response to previous episodes (to twipo@solvingkidscancer.org) will be read and discussed. We anticipate each episode will last 15-20 minutes.

TWiPO #21 ~ Interview with Dr. Beatrice Lampkin | Dr Tim Cripe and co-hosts Dr Maureen O'Brien and Dr Raj Nagarajan interview a pediatric hematology/oncology legend, Dr. Beatrice Lampkin, who served as Division Director of Cincinnati Children's Division of Hematology/Oncology in the 1970âs. This enlightening and inspiring discussion explores her career and her early contributions to leukemia therapy and the challenges she faced as an early leader in the field as a female. She describes her experience with polio, early 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 used the term "anemia" to describe their child's condition rather than "leukemia" to to explain why the child would require periodic blood transfusions, and to prevent shunning by friends and family. Dr Lampkin also describes her joy at following the earliest survivors of pediatric cancer she treated who are now in their 40s and 50s. As if all that isn't inspiring enough, she describes her busy retirement in which she continues to teach the Cincinnati Children's Hospital fellows how to examine blood and bone marrow smears under the microscope and her work in the founding of the GLAD House (http://www.gladhouse.org/), a sanctuary to help drug-addicted youth get off the streets.

TWiPO #20 ~ The F-word in Pediatric Cancer Research | Todayâs episode features an impressive lineup for a hot topic. Host Dr Tim Cripe warns: âIf your blood isnât boiling by the end, you weren't listening.â 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 â private donations to St Jude exceed $600M per year, on top of the giversâ 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. | 11/15/11 | Free | View In iTunes |

TWiPO #11 ~ BuMel SIOP results and MIBG transplant with Dr Brian Weiss | SIOP's BuMel results discussed, implications for COG 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 Please send questions and comments to twipo@solvingkidscancer.org | 7/12/11 | Free | View In iTunes |

TWiPO #10 ~ Interview with Dr Robert Seeger | Top neuroblastoma researcher discusses career, advances in research "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 â 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 Seegerâs 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 | Chair of Children's Oncology Group (COG) discusses career, drug development Host Dr Tim Cripe of  "This Week in Pediatric Oncology" podcast interviews Dr Peter Adamson, new COG Chair. 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. Reference: Making Better Drugs for Children with Cancer. Institute of Medicine Consensus Report. Peter C. Adamson, Susan L. Weiner, Joseph V. Simone, and Hellen Gelband, Editors. April 18, 2005 Background: Dr Adamson was elected by principal investigators of more than 200 Children's Oncology Group sites. COG includes more than 5,000 experts in childhood cancer at leading childrenâs hospitals, universities and cancer centers across North America, Australia, New Zealand and Europe. In 1999 Dr. Adamson came to The Childrenâs Hospital of Philadelphia (CHOP) from the National Cancer Institute (NCI), and is the director of Clinical and Translational Research and chief of the Division of Clinical Pharmacology and Therapeutics at Children's Hospital. He also is a professor of Pediatrics and Pharmacology at the University of Pennsylvania School of Medicine. He remains on the staff of Children's Hospital and on the Penn faculty while serving as Children's Oncology Group chair. Dr. Adamsonâs previous roles at COG include leading the 21-site phase 1 consortium. During the eight years that Dr. Adamson led this effort, the collaborating sites conducted more than 25 studies designed to test the safety of novel anticancer drugs. Says Dr Adamson, "I hope to fully leverage the emerging discoveries being made at a rapid pace by transforming how research moves from the bench to the bedside in a very large collaboration." Dr. Adamson received his MD from Cornell University and completed his residency at CHOP in 1987. He then spent 10 years at the NCI where he finished his fellowship in Pediatric Hematology/Oncology and Biotechnology, and worked as an investigator and an attending physicians before coming to CHOP.
