p-values relate to comparison Tions at opposite locations (red) and within-object places (blue) plotted against between all three groups. Next, we compared outcome between (i) patients with mutation heterogeneity affecting either KRAS, BRAF, PI3K or TP53 across metastatic deposits (n 5 13), (ii) title= 1479-5868-9-35 patients harboring a homogeneous mutation in at least one gene across all metastatic deposits and with no heterogeneous mutation and (iii) patients with no mutations across either gene. Comparing all three groups, univariate analysis revealed asignificant different TTR (median of 4 vs. 5 vs. 15 months, p title= ejsp.2064 58 months, p 65 years) Sex (male vs. female) Nodal status of primary (N1 vs. N0) Synchronous vs. metachronous mets.
