International Speakers - Radiation Oncology

Chris Crane

Dr Chris Crane

Christopher Crane, MD, is Vice Chairman and Gastrointestinal Section Leader in the Department of Radiation Oncology at Memorial Sloan Kettering Cancer Center. He also serves as Chair of the Non-colorectal subcommittee of NRG Oncology. He is an internationally recognized expert in the in the treatment of gastrointestinal malignancies. He is currently focused on the developing ablative radiation strategies in the curative treatment of liver and pancreatic cancers. He has pioneered techniques to address organ motion management challenges by incorporating image guidance and adaptive treatment planning using universally available technologies. He is also involved in defining the future role of MRI image guidance and that will make these complex techniques more readily available. He has also conducted clinical trials in pancreatic, liver, anal, and rectal cancers focusing on the combination of molecular targeted therapies with radiotherapy as well as correlative studies focused on the development of predictive markers.


Sean Collins

Associate Professor Sean Collins

Sean Collins, MD, PhD, joined his twin brother Brian on the faculty of the cancer center in July of 2006 as an attending physician in radiation oncology. He graduated from the MSTP Program at the University of Michigan in 2001. Dr. Collins completed both an internship in surgery and a residency in radiation oncology at Georgetown University Hospital. His area of expertise is prostate cancer, for which he treats patients using the CyberKnife, a technology that allows for more accurate targeting of radiation therapy. Dr. Collins is a physician-scientist which means he conducts clinical and laboratory research. The focus of his clinical work is to develop prostate cancer treatment protocols using stereotactic body radiation therapy (SBRT) to minimizing the toxicity of radiation dose escalation. To date he has treated over 1300 prostate cancer patients with SBRT and has presented his work at major meeting and published multiple papers on his experience in peer reviewed journals.


Heiko Enderling

Associate Professor Heiko Enderling

Heiko Enderling, PhD, is Associate Professor of Integrated Mathematical Oncology and Radiation Oncology at H. Lee Moffitt Cancer Center and Research Institute in Tampa, Florida. He also serves as the Director for Education and Outreach in the Moffitt Physical Sciences in Oncology Center and on the Board of Directors of the Society for Mathematical Oncology. He directs a research group on Quantitative Personalized Oncology with the aim to integrate mathematical, biological and clinical science to simulate tumor growth and forecast treatment response for individual patients.

Dr. Enderling graduated with an applied computer engineering degree from the University of Magdeburg, Germany, in 2003, and completed his PhD in Mathematical Biology at the University of Dundee, Scotland, in 2006. His work focusses on using pre-treatment tumor growth dynamics to identify optimal radiation dose and dose fractionation for individual patients, and to evaluate tumor response data for adaptive therapy. Additionally, his work evaluates synergy of radiation with systemic agents including immunotherapy for improved patient responses and treatment outcomes.

He is an active clinician and clinical research investigator on the Gastrointestinal Cancer multi-disciplinary team. He holds the Frank T. McGraw Memorial Chair for the Study of Cancer.

Dr. Minsky received his medical degree from the University of Massachusetts in 1982. He was a Medical Intern at New England Deaconess Hospital and completed his residency in radiation therapy at the Harvard Joint Center for Radiation Therapy. Following completion of his residency in 1986 Dr. Minsky spent the first 20 years of his career at Memorial Sloan Kettering Cancer Center as a clinician and clinical research investigator in Gastrointestinal Cancer. While at MSKCC, he was also the Vice Chair of Radiation Oncology from 2000-2007 and achieved the rank of Professor of Radiation Oncology at Cornell University in 1999. In 2004, he received a medical degree honoris causa from Friedrich Alexander University, Erlangen, Germany in recognition for his work in gastrointestinal cancers. He received the MSKCC Distinguished Alumni Award in 2008. From 2007 to 2012 Dr. Minsky served as a Professor of Radiation and Cellular Oncology and Associate Dean in the Biological Sciences Division at the University of Chicago. During that time he was also the Chief Quality Officer at the University of Chicago Medical Center.

Dr. Minsky is an editorial board member of several journals and has lectured and published widely. He is the co-chair of the NCI Gastrointestinal Steering Committee and has served on the board of directors for both the ASTRO and ASCO. He was the 2015 ASTRO President, elected an honorary member of ESTRO in 2014, and became a Fellow of ASCO (FASCO) in 2018.


Birgitte Offersen

Professor Birgitte Offersen

Professor Offersen is the head of the Danish Breast Cancer Group (DBCG) Radiotherapy Committee and a member of the DBCG Board. She is the Breast Editor on the Radiotherapy & Oncology, and a member of several IDMCs for randomized trials. Since 2009, she has been a teacher on ESTRO’s (European Society for Radiotherapy & Oncology) courses on Multidisciplinary Management of Breast Cancer, Partial Breast Radiotherapy, and the Online Breast Contouring. As part of the latter, she was leading an ESTRO Consensus Guideline on Target Volume Delineation in Early Breast Cancer, which has become the standard in most European radiotherapy centres.

She graduated from Aarhus University in 1995. In 2002, she completed her PhD on tumour microenvironment. In 2007, she specialised as a clinical oncologist and subsequently developed an interest in breast cancer radiotherapy. In 2009, she initiated the DBCG HYPO and DBCG PBI randomized trials where a dose of 40 Gy in15 fractions was tested both in relation to 50 Gy in 25 fractions (HYPO trial) and to whole breast irradiation versus partial breast irradiation (PBI trial). The outcomes from these trials have led to new national standards in the practice of Radiation Oncology in Denmark. Professor Offersen is also the principal investigator on the randomized Skagen trial 1 investigating loco-regional radiotherapy comparing doses of 50 Gy in 25 fractions and 40 Gy in15 fractions. This trial is currently active in nine countries. Later this year, further two randomized trials – with Professor Offersen as the principal investigator – will open for accrual: the DBCG RT Recon trial testing loco-regional postmastectomy radiotherapy following breast reconstruction, and the DBCG RT Natural trial evaluating omission of adjuvant radiotherapy.
