PIK3CA and neoplasm: PIK3CA H1047R and BRAF V600E MFs were correlated positively with maximum tumor dimension (r = 0.46, p ≤ 0.01; and r = 0.47, p ≤ 0.001, respectively), while KRAS G12V MF was correlated negatively with maximum tumor dimension (r = −0.65), although this did not reach the level of statistical significance (Table 4, Figure 5; using only samples with a MF ≥ 1 × 10−5).
