Clinical practice guidelines

US Preventive Services Task Force (USPSTF) issued an updated assessment in 2022 removing their earlier recommendation regarding the use of aspirin: “The evidence is unclear whether aspirin use reduces the risk of colorectal cancer incidence or mortality.”1US Preventive Services Task Force, Davidson KW, Barry MJ et al. Aspirin use to prevent cardiovascular disease: US Preventive Services Task Force recommendation statement. JAMA. 2022 Apr 26;327(16):1577-1584. Related to cardiovascular disease (CVD), “the USPSTF recommends against initiating low-dose aspirin use for the primary prevention of CVD in adults 60 years or older.”2Aspirin Use to Prevent Cardiovascular Disease: Preventive Medication. US Preventive Services Task Force. April 26, 2022. Viewed June 30, 2023.

Expert commentary

Laura Pole, RN, MSN, OCNS, CancerChoices senior clinical consultant: Although a meta-analysisa statistical analysis that combines the results of two or more research studies; the results of smaller research studies addressing the same or similar questions can be analyzed as though they are one bigger, more powerful study3Huang R, Jiang L et al. Comparative efficacy of therapeutics for chronic cancer pain: a Bayesian network meta-analysis. Journal of Clinical Oncology. 2019 Jul 10;37(20):1742-1752. lists the combination of aspirin and codeine as having strong evidence of reducing chronic cancer pain, aspirin, at least in the US, is rarely used either alone or combined with an opiate for chronic, persistent cancer-related pain. In doses that relieve pain, the side effects of long-term use—increased bleeding risk and ulceration of the stomach—outweigh the benefits. Rather, common practice is to use acetaminophen (Tylenol) either alone for mild pain or in combination with opioids for higher levels of pain.
