We also observed a highly significant difference ( P < 0.0001) in the proportion of PtR patients (92.5%) compared to PtS patients (7.5%) with TP53 copy loss in the metastatic tumor.

Although remarkable differences in the number of breakpoints in primary tumors between PtS and PtR patients (Supplemental Table S4a) were not observed, the mean number of breakpoints for primary tumors in chromosomes 1, 8, 11, 17 (Figure 1A ) was observed to be higher and approached near significance in PtS versus PtR patients (chr1 P -value = 0.059, chr8 P -value = 0.056, chr11 P -value = 0.068, chr17 P -value = 0.058).
