Sequencing Analysis of Tumor DNA: Is It All in the Plasma?
Massively parallel sequencing analyses have demonstrated that most of the common malignancies display relatively complex repertoires of somatic genetic alterations, that the number of highly recurrent mutations is limited, and that a large number of genes is mutated in a small minority of tumors...
Potential of Liquid Biopsies in Detecting Cancer and Establishing Prognosis
Tests in development to detect circulating tumor cells that escape from solid tumors and travel through the blood, spreading cancer to new sites, may serve as an alternative to conventional tissue biopsy for early cancer diagnosis and gene-expression analysis over the next decade. According to...
