Bone marrow aspiration being somehow invasive, we then investigated whether the detection of circulating tumor cells (CTC) in the blood could be used as a biomarker of early tumor relapse or progression. (science.institut-curie.org)
This treatment prevented the formation of polyps, showing that bacteria are essential for early tumor development in this model. (sciencedaily.com)
The presenter pointed out that genes that confer advantages for metastasis (invasion) alone have no Darwinian selective advantage in early tumor development. (massgenomics.org)
