57 Background: It has been suggested that the sequential analysis of the mutational spectra at loci involved in the pathogenesis of tumors (mutational load distribution analysis [MLDA]) may reflect the biology of the tumor and/or the risk of cancer before the tumor emerges. Metrics derived from MLDA could assist quantifying risk, in early diagnosis...

Concomitant quantification of multiple mutant KRAS (v-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog) alleles may provide information in addition to that provided by standard mutation-detection procedures. We assessed the feasibility of a nanofluidic digital PCR array platform to detect and quantify KRAS mutations simultaneously in clinically r...

... Digital droplet PCR (ddPCR) is a promising tool for detecting resistant strains and monitoring therapeutic response with better sensitivity than conventional RT-PCR [8][9][10]. ddPCR can accurately measure the absolute nucleic acid count of single template molecules without the need for standard curves, is less susceptible to interference from PCR inhibitors, and can generate up to 20,000 droplets per sample, allowing a very low limit of detection (0.005%) [8][9][10]. ...
