Abstract 767: Comparison of different methods for the detection of clusters of circulating tumor cells

BACKGROUND: In the last few years, there has been an increase in research interest and number of studies investigating clusters of circulating tumor cells (CTC clusters) due to their putative higher metastatic potential compared to individual CTCs. Although the majority of studies suggest a link between CTC clusters and worse clinical outcome, their clinical significance and biological role is still not fully demonstrated. A hurdle to this aim...
