The Origin and Common Misconceptions About the Current ASTRO Guidelines For The Use Of APBI

Webinar Series:

Presented by:
Robert Kuske, MD, FAACE
Arizona Breast Cancer Specialists
Scottsdale, AZ


Dr. Kuske discusses the origin and common misconceptions about the current ASTRO guidelines for the use of APBI. In addition to discussing his own experiences, he reviews the emerging data, particularly in more controversial subsets, such as women with ER negative tumors, DCIS, and younger age (< 60 years). Dr. Kuske also explains how strut-based brachytherapy can expand the ability to treat eligible patients where anatomical restrictions prevent the use of balloons.


Dr. Robert Kuske is a radiation oncologist at Arizona Breast Cancer Specialists in Scottsdale, Arizona. He previously led the breast cancer program at the University of Wisconsin and was chairman of Radiation Oncology at the famed Ochsner Clinic in New Orleans. While in New Orleans, Dr. Kuske and colleagues pioneered accelerated partial breast irradiation, and he is now a co-principal investigator of the North American 4300 patient phase III trial through the NSABP and RTOG, approved and funded by the National Cancer Institute. In April 2011, Dr. Kuske received the American Brachytherapy Society Presidential Award for contributions to the science of his field of radiation oncology.

Lower Toxicities With Strut-based Brachytherapy: 4-year Results

Webinar Series:

Presented by:
Catheryn Yashar, MD
Moores Cancer Center
UC San Diego, CA


Dr. Yashar reviews the most recent data available on early and late toxicity outcomes with strut-based brachytherapy. She discusses data presented at ASBD 2012 showing very low toxicity over time in patients with 24 months follow-up, mirrored by the most recent results presented at the 2012 World Congress of Brachytherapy on patients with four years median follow-up. In addition, Dr. Yashar discusses how the excellent dosimetric parameters of strut-based brachytherapy were demonstrated in a study presented at ACRO 2012 of over 800 patients from 12 institutions, allowing researchers to expand the number of eligible women they were able to treat with APBI.


Dr. Yashar is Associate Professor and Chief of Breast and Gynecologic Radiation Services at UC San Diego. Her clinical and research focus has centered on breast and gynecologic cancers, especially IMRT, IGRT and brachytherapy techniques. She is one of the first adopters of the technology and a co-principle investigator of the SAVI Collaborative Research Group, formed to study the long-term outcomes with strut-based brachytherapy. Dr. Yashar has spoken at several national and international meetings on brachytherapy, and is a guest reviewer for several renowned journals.
