Nuclear Medicine Therapy Increases Survival for Patients with Colorectal Cancer Liver Metastases

07.11.2013
For patients who fail to respond to current first-line and second-line treatments for colorectal cancer liver metastases (also known as salvage patients), radioembolization with Y-90 microspheres could extend survival according to new research published in the November issue of The Journal of Nuclear Medicine.

A systematic review conducted by researchers showed that approximately 50 percent of salvage patients have an overall survival of more than 12 months after this nuclear medicine therapy.

Colorectal cancer is the third most commonly diagnosed type of cancer worldwide in men and the second in women, and it is also the third most common cause of death. In approximately 50 percent of patients, metastases to the liver are present at diagnosis or during follow-up, which account for a large portion of morbidity and mortality in patients.

A structured review was performed by researchers to gather all available evidence on radioembolization for the specific group of patients with colorectal cancer liver metastases. “Although quite some reviews are printed on the subject of radioembolization, we felt that a structured and comprehensive review on survival and response data for these patients was lacking,” said Charlotte E.N.M. Rosenbaum, PhD, lead author of the study “Radioembolization for Treatment of Salvage Patients with Colorectal Cancer Liver Metastases: A Systemic Review.”

Researchers reviewed a total of 13 articles on Y-90 radioembolization as a monotherapy and 13 articles on Y-90 radioembolization as a combined with chemotherapy. Among the studies, disease control rates (i.e., complete response, partial response and stable disease) ranged from 29-90 percent in the monotherapy studies, which involved 901 patients. In the studies in which Y-90 radioembolization was combined with chemotherapy, involving 472 patients, disease control rates ranged from 59-100 percent.

“From the studies included in this systematic review, survival proportions of approximately 50 percent were found. Therefore, in this group of salvagecolorectal cancer liver metastases patients who otherwise have no regular treatment options and a life expectancy of less than six months, Y-90 radioembolization seems to be a hopeful treatment option,” noted Rosenbaum.

She continued, “Our paper shows all published data on this subject from the first randomized trial onwards. Furthermore, we have determined 12-month survival proportions for all included articles to provide a better overview and to better allow for comparisons. Finally, this overview of the literature shows which topics have not been the focus of much research and may thus be interesting for further work.”

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
