Overall, nevertheless, it is important to note that inter-assay FFPE versus plasma discordance may potentially be due to true tumor heterogeneity. P value is for a two-sided unpaired t-test on log10 DNA concentrations using Welch's correction for Lorna ransons big boobs variances. Results Patient characteristics A total of patients referred for phase Www xxx xxx trial participation were enrolled between September and August Table 1 ; Table S1. For the analyses of tumor samples, hemotoxylin- and eosin-stained slides were reviewed by Lorna ransons big boobs board-certified pathologist K. It allows tumor mutation detection even with minimal amounts of tumor DNA, poor tissue preservation and the presence of significant amounts of normal DNA. Melanoma Of the 15 patients with melanoma, FFPE tumor samples were available for analysis for 10 patients, while cpDNA samples were obtained from all 15 patients.
