TWiPO #64 - Interview with Dr. Lars Wagner

July 17th, 2017 · Comments

It’s an exciting time to be part of the childhood cancer research community, and this interview was focused on career advice for those interested in childhood oncology and research. The availability of genomic profiling of tumors, targeted agents and the development of new immunotherapies are increasing the opportunities available to patients today. This lively discussion addresses the importance of preclinical data, predictive biomarker studies and the measurement of responses, with specific references to Dr. Wagner’s experience with studying irinotecan.   Dr. Wagner also answered questions about radiomics and how this imaging trend can provide more insights for enhanced radiology reporting.

TWiPO #19 ~ More on Hedgehog signaling, brain tumor risk from cell phone use, and FDA approval of cancer drugs

February 10th, 2014 · Comments

October 30, 2011

Several just-published papers in the literature relate to recent podcast episodes, and host Dr. Tim Cripe and co-host Dr.  Lionel Chow review these interesting developments.

0:55 Hedgehog Signaling: Recent papers discussing this pathway in neuroblastoma and rhabdomyosarcoma are discussed, with implications for treatment in these tumor types with itraconozole.

6:40 Cell phone and brain tumor risk: The controversy concerning criticism by the Environmental Health Trust of a study showing that cell phone use does not increase risk of brain tumors in children is explored.

Accelerated approval of cancer drugs by the FDA and implications for pediatric cancers.

15:30 Brentuximab for two types of lymphoma

21:20 Vemurafenib for melanoma

28:30 Crizotinib for non-small cell lung cancer (and potential use in neuroblastoma)

TWiPO #18 ~ Targeting EWS-FLI1 in Ewing’s Sarcoma: Interview with Dr Jeff Toretsky

February 10th, 2014 · Comments

October 18, 2011

Host Dr. Tim Cripe and co-host Dr. Lionel Chow welcome special guest Dr. Jeff Toretsky on TWiPO to discuss his clinical and research interest in Ewing's sarcoma. Dr. Toretsky explains the challenges of developing a clinical grade drug from a small molecule for a specific target such as EWS-FLI1. The small market for a disease like Ewing's creates formidable hurdles for researchers, yet Dr. Toretsky is driven on by the question "If I don't do this, who will?" (17:54 mins)

Dr. Jeff Toretsky is Professor of Oncology and Pediatrics at Georgetown University. He graduated with BS in Biochemistry from University of Wisconsin, Madison, WI, and recieved his MD from University of Minnesota, Minneapolis, MN. He completed fellowship training at the NCI Pediatric Branch.
