Fig. 4 — Correlation of overall survival with the PIK3CA mutation status in breast cancer. a Kaplan-Meier analysis comparing patients with mutated PIK3CA (green line) and wild type PIK3CA (blue line) did not reveal a statistically significant difference in survival. b Kaplan-Meier analysis of the PIK3CA mutation status stratified for the affected exon did not reveal a statistically significant difference in survival, but there was a trend toward better survival for the cases with a mutation in exon 9. Exon 9 mutation (p = 0.39) vs. exon 20 mutation (p = 0.41) vs. other exon mutations (p = 0.16)
