Circulating tumor cell (CTC) clusters — clumps of from 2 to 50 tumor cells that break off a primary tumor and are carried through the bloodstream — appear to be much more likely to cause metastasis than are single CTCs, according to a study from investigators at the Massachusetts General Hospital (MGH) Cancer Center.

According to recent research, the most common solid tumors (that is, cancer that occurs as clusters of cells in or on organs, rather than in liquid form within the blood or lymphatic system) have up to 66 mutations that influence how the cancer cells operate — how fast they divide, whether they are susceptible to the signals that would normally cause a cell to die, when they detach from the main tumor to colonize another organ in the body, when and where they attach blood vessels to healthy tissues.

Human pathology studies suggest that tumor cells invade collectively as strands, cords and clusters of cells into the stroma, which is dramatically reorganized during cancer progression.
