Study on Aspirin Versus Placebo in Resected Colon Cancer With PI3K Mutation Stage III or II High Risk (ASPIK French)

October 23, 2019 updated by: University Hospital, Rouen

French Prospective Randomised Double Blind Study, on Aspirin Versus Placebo in Resected Colon Cancer With PI3K Mutation

Four retrospective studies were recently published on efficacy of aspirin in patients with surgically resected colon cancer. Two of these studies strongly suggested that aspirin used in low doses (100 mg/d) after surgical resection of colorectal cancer with PI3K mutation could act as a targeted therapy with a major protective effect on the risk of recurrence. The other two studies did not confirm the benefit of aspirin in this situation. These four retrospective studies provide an insufficient level of evidence to demonstrate the benefit of low-dose aspirin as adjuvant to surgery for colorectal cancer. Therefore, it is necessary as recommended in the conclusion of these studies and meta-analyses to perform a randomised prospective study to validate these data.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Patient with aspirin intake
Surgical resection of colonic adenocarcinoma stage III or II high risk will be done in accordance with local guidelines. Molecular analysis of exon 9 and 20 of PI3K will be done using operative piece. If the mutation is detected, patient with colonic adenocarcinoma stage III or II high risk will take aspirin 100 mg/day during 3 years. Blood intake will be done every 6 months to evaluate patient compliance to treatment
Patient with colonic adenocarcinoma stage III or II high risk will take aspirin 100 mg/day during 3 years
Surgical resection of colonic adenocarcinoma stage III or II high risk will be done in accordance with local guidelines
Molecular analysis of exon 9 and 20 of PI3K will be done using operative piece
Blood intake will be done every 6 months to evaluate patient compliance to treatment
Placebo Comparator: Patient with placebo intake
Surgical resection of colonic adenocarcinoma stage III or II high risk will be done in accordance with local guidelines. Molecular analysis of exon 9 and 20 of PI3K will be done using operative piece. If the mutation is detected, patient with colonic adenocarcinoma stage III or II high risk will take placebo of aspirin 100 mg/day during 3 years. Blood intake will be done every 6 months to evaluate patient compliance to treatment
