Abstract

Objective: Doxorubicin is a valuable chemotherapeutic drug; however, it is associated with a high risk of cardiotoxicity. Several institutions and organizations have developed guidelines for risk factor assessment, monitoring and prevention strategies against chemotherapy-induced cardiotoxicity. This review aimed to assess the quality of current practice guidelines, using the Appraisal of Guidelines for Research and Evaluation II (AGREE II). This tool was used to compare the recommendations with regards to their strength and evidence recommendations were based on.

Data sources: This review identified guidelines in literature from January 1960 to February 6, 2022, through a systematic search that included PubMed, EMBASE, MEDLINE, Cochrane Database and Google Scholar. The quality, consistency and the strength of supporting evidence was evaluated using the AGREE II method.

Data summary: Eight guidelines met the inclusion criteria and 144 recommendations were extracted from these guidelines. The results from the AGREE II evaluation showed that the total assessment scores of guidelines ranged from 2 to 5, indicating the guidelines need modifications. The recommendations were evaluated according to the references used, and it was found that 12 (11%) recommendations had high evidence, 36 (33%) had moderate evidence, 38 (35.19%) had low and 22 (20.37%) had insufficient evidence. Recommendations for risk factors assessment, prophylaxis of cardiotoxicity, management of cardiotoxicity and monitoring of cardiotoxicity were quite varied amongst the different guidelines evaluated.

Conclusions: All studied guidelines need modifications as per the AGREE II evaluating tool. Several shortcomings were identified, including a lack of evidence-based studies supporting the recommendations in the guidelines.

Keywords: Doxorubicin; assessment; guideline; management; monitoring.
