1 Recent data have suggested that the benefit of aspirin after CRC diagnosis is limited to patients with PIK3CA-mutant cancers. Aspirin phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha Homo sapiens
2 We sought to determine the predictive utility of PIK3CA mutation for benefit from both cyclooxygenase-2 inhibition and aspirin. Aspirin phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha Homo sapiens
3 In contrast, regular aspirin use after CRC diagnosis was associated with a reduced rate of CRC recurrence in patients with PIK3CA-mutant cancers (HR, 0.11; 95% CI, 0.001 to 0.832; P = .027; (P)INTERACTION = .024) but not in patients lacking tumor PIK3CA mutation (HR, 0.92; 95% CI, 0.60 to 1.42; P = .71). Aspirin phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha Homo sapiens
4 In contrast, regular aspirin use after CRC diagnosis was associated with a reduced rate of CRC recurrence in patients with PIK3CA-mutant cancers (HR, 0.11; 95% CI, 0.001 to 0.832; P = .027; (P)INTERACTION = .024) but not in patients lacking tumor PIK3CA mutation (HR, 0.92; 95% CI, 0.60 to 1.42; P = .71). Aspirin phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha Homo sapiens
5 Our findings are concordant with recent data and support the prospective investigation of adjuvant aspirin in PIK3CA-mutant CRC. Aspirin phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha Homo sapiens
