Warren symposium follows legacy of geneticist giant

If we want to understand how the brain creates memories, and how genetic disorders distort the brain’s machinery, then the fragile X gene is an ideal place to start. That’s why the Stephen T. Warren Memorial Symposium, taking place November 28-29 at Emory, will be a significant event for those interested in neuroscience and genetics. Stephen T. Warren, 1953-2021 Warren, the founding chair of Emory’s Department of Human Genetics, led an international team that discovered Read more

Tracing the start of COVID-19 in GA

At a time when COVID-19 appears to be receding in much of Georgia, it’s worth revisiting the start of the pandemic in early 2020. Emory virologist Anne Piantadosi and colleagues have a paper in Viral Evolution on the earliest SARS-CoV-2 genetic sequences detected in Georgia. Analyzing relationships between those virus sequences and samples from other states and countries can give us an idea about where the first COVID-19 infections in Georgia came from. We can draw Read more

Seeing the value: prostate cancer imaging agent developed at Winship

A study from Winship Cancer Institute of Emory University has the potential to change how patients whose prostate cancer recurs after prostatectomy are treated. The study was featured in both the plenary session and press program of the American Society for Radiation Oncology (ASTRO) Annual Meeting on Monday, October 26.

The Emory Molecular Prostate Imaging for Radiotherapy Enhancement, or EMPIRE-1 trial (NCT01666808), is the first randomized trial of men with prostate cancer with recurring cancer to show that treatment based on advanced molecular imaging can improve disease-free survival rates. The molecular imaging used in the study, the radiotracer fluciclovine (18F) PET, was invented and developed at Emory and Winship.

The phase II/III trial was led by Winship radiation oncologist and prostate cancer specialist Ashesh B. Jani, MD, MSEE, FASTRO, and Winship nuclear radiology specialist David M. Schuster, MD, FACR. The trial enrolled 165 patients whose cancer recurred after having undergone prostatectomies. One group received radiation therapy based on conventional imaging. The other group received treatment that was finalized based on imaging with the fluciclovine PET radiotracer. Those whose treatment was adjusted according to the results of the advanced molecular imaging showed an improvement in the cancer control end point.

“At three years, the group getting treatment guided by PET fluciclovine had a 12 percent better cancer control rate, and this persisted at four years as well, with a 24% improvement,” says Jani. “We think the improvement was seen because the novel PET allowed for better selection of patients for radiation, better treatment decisions, and better radiation target design.”

Fluciclovine PET imaging has been getting some attention in the urology/prostate cancer world.
