Background

Anticancer drug interactions can affect the efficacy and toxicity of anticancer treatment and that of the interacting drugs. However, information on the significance, prevention, and management of these interactions is currently lacking.

Objective

The purpose of this study was to assess the clinical significance of interaction among anticancer agents and comedications and to provide recommendations for the management of clinically significant interactions.

Methods

Members of a multidisciplinary expert group of hospital and community pharmacists, medical oncologists, internists, and clinical pharmacologists were selected by their professional organizations, which participated in this consensus project. Literature was extensively searched for any drug interactions with anticancer agents using registration files, reference books, handbooks, and electronic databases. Interactions between anticancer agents were not considered. Interactions were classified by level of best available evidence for the interaction and by severity of the clinical effect, according to a structured assessment procedure. This assessment distinguished 5 levels for the amount and quality of evidence available and 6 severity levels for classification of potential drug-to-drug interactions.

Results

A total of 88 drug interactions with anticancer agents were identified from 146 combinations of drugs with anticancer agents found in literature. For 58 combinations, there was insufficient evidence of an interaction. Of the identified interactions, 38 were classified as clinically significant, defined as necessitating an alert or intervention, such as dose adaptation, comedication, discontinuation of treatment, or additional monitoring of treatment. Recommendations were made for management of these interactions.

Conclusion

Numerous interactions with anticancer agents are clinically significant and should be considered by pharmacists and doctors in daily oncology practice.
