Davies7  \nReceived: 10 May 2025 / Accepted: 25 June 2025 © The Author(s) 2025  \nAbstract  \nPurpose Beta-blockers, originally developed for cardiovascular conditions, have been explored for their potential role in cancer treatment. Propranolol, a non-selective beta-blocker, has shown promise in inhibiting stress-induced signalling pathways associated with cancer progression. This systematic review aims to assess the evidence for the repurposing of propranolol as a treatment for various cancers, particularly breast cancer to answer the research question: Does propranolol improve cancer outcomes, including survival and recurrence?  \nMethods We conducted a systematic search of MEDLINE, EMBASE, Global Health, Web of Science, and the Cochrane Library, including studies up to July 2024. Randomised Controlled Trials (RCTs), systematic reviews, and meta-analyses were included if they assessed the effects of propranolol on cancer outcomes such as mortality, survival, recurrence, or biomarkers of tumour regression. A narrative synthesis was performed to summarise the findings.  \nResults Thirty-one studies were included, consisting of 7 RCTs, 4 systematic reviews and 20 meta-analyses. The evidence suggests that propranolol may improve cancer outcomes, especially when administered perioperatively, by reducing recurrence risk. However, the results remain inconclusive regarding its use in combination with chemotherapy or radiotherapy, as studies showed mixed results. The timing of propranolol administration, alongside its combination with other cancer therapies, appears to be a key factor in its effectiveness.  \nConclusion Propranolol has potential as an adjunctive therapy in cancer treatment, particularly in reducing recurrence risk during the perioperative period. However, further clinical trials are needed to better define its role in cancer therapy, particularly regarding optimal treatment regimens and patient populations.  \nKeywords Beta-blockers · Propranolol · Cancer treatment · Systematic reviews · Repurposing  \nIntroduction  \nThe lengthy process of developing new cancer therapies maybe expedited through drug repurposing or repositioning, which involves identifying new therapeutic applications for  \n􀀍 Jessica O’Logbon [j.ologbon@nhs.net](j.ologbon@nhs.net)  \n1 Guy’s and St. Thomas’NHS Trust, St Thomas’Hospital, Westminster Bridge Rd, London SE1 7EH, UK  \n2 GKT School of Medical Education, Guy’s Campus, Great Maze Pond London, London SE1 1UL, UK  \n3 Prostate Cancer Research Centre at the Centre for Stem Cell and Regenerative Medicine, 28 Floor Guy’s Hospital, King’s College London, Great Maze Pond, London SE1 9RT, UK  \nexisting medications (Issa et al. 2013; Xia et al. 2024) .
