Objective: This review aims to summarize existing interventions from the international literature addressing fertility concerns in cancer patients, providing theoretical and practical guidance for future interventions. Methods: In September 2023, a systematic search covering 13 databases was conducted using the methodology outlined by the Joanne Briggs Institute for a comprehensive systematic review. This search identified published English and Chinese-language papers. Results: A total of 20 studies meeting inclusion criteria were included in this review. The studies predominantly originated in China and the United States. A comprehensive synthesis of interventions from the included literature across three dimensions and seven aspects was conducted. The interventions primarily focused on psychological interventions and web-based self-help tools for patients. The Reproductive Concerns After Cancer Scale (RCAC) was the primary assessment tool employed. Conclusion: Addressing fertility concerns in cancer patients is a complex issue involving various stakeholders and diverse intervention strategies. Lessons from international research can inform the development of context-specific interventions tailored to individual needs.
