As a genomic disease, cancer involves a series of changes in the genome from primary tumors, via circulating tumor cells (CTCs), to metastases that cause the majority of mortalities.The genome sequencing of CTCs could offer non-invasive prognosis or even diagnosis, but has been difficult due to their low abundance.Here we report the use of Multiple Annealing and Looping-Based Amplification Cycles (MALBAC) for whole genome amplification of single CTCs from lung patients.Single nucleotide variations (SNVs) and insertions/deletions (INDELs) in exomes of CTCs can be detected and were heterogeneous from cell to cell.
