Abstract
Treatment with dual antiplatelet therapy (DAPT), typically combining a P2Y12 inhibitor with aspirin, is the standard of care for the prevention of coronary stent thrombosis, especially post revascularization and in the setting of acute coronary syndromes (ACS). Determining the appropriate duration has been debated as prolonged courses have been associated with reduced thrombotic complications. Despite proven benefit, there have been reports of a potential cancer risk associated with DAPT following the FDA's review of the TRITON-TIMI 38 trial and the DAPT trial. The latter revealed an increased risk of non-cardiovascular death, which was driven by more bleeding and cancer-related deaths. This further clouds the decision if longer courses of DAPT should be recommended. Several trials and meta-analyses have been conducted to further review this cancer risk with P2Y12 inhibitors. This manuscript intends to evaluate current literature to determine if there is a risk of cancer for patients on DAPT and its consequences in the management of cardiovascular disease.
