Median survival was determined for patients from the METABRIC database, stratified by TP53 mutation status and treatment exposure. Studies that analyzed patients under similar treatment conditions are listed in adjacent captions. (A) All patients (P <0.0001). (B) All chemotherapy-treated patients (P = ns). (C) All patients who did not receive chemotherapy (P <0.0001). (D) All patients treated with chemotherapy + HRT (P <0.05). (E) All patients treated with chemotherapy alone (P <0.05). (F) All patients treated with HRT only (P <0.0001). (G) All patients who did not receive chemotherapy or HRT (P = ns). Abbreviations: HRT, hormonal therapies; mut, mutant; ns, not significant; OS, overall survival; WT, wild type. (See [9,39–49,52–54,65–91].)
