This meta\u2010analysis evaluates ruxolitinib's efficacy and safety against best available therapy (BAT) in patients with PV and in hydroxyurea\u2010resistant\/intolerant PV patients. A comprehensive literature search was conducted up to November 2023. We compared ruxolitinib and BAT for efficacy and safety endpoints. Six studies involving 1061 patients were analyzed, with 620 on BAT and 441 on ruxolitinib. Ruxolitinib showed higher hematocrit control (p\u2009=\u20090.015) and treatment response (p\u2009=\u20090.04) compared to BAT. It also significantly improved Myeloproliferative Neoplasms\u2010Symptom Assessment Form scores (MPN\u2010SAF) (p\u2009&lt;\u20090.01). Additionally, patients with PV treated with ruxolitinib had higher rates of nonmelanoma skin cancer (p\u2009&lt;\u20090.01). In subgroup analyses focusing on patients resistant or intolerant to hydroxyurea, ruxolitinib maintained its efficacy, significantly improving treatment response (p\u2009&lt;\u20090.01) and significant improvements in MPN\u2010SAF (p\u2009=\u20090.02) score when compared to BAT. The safety profile was consistent with the overall analyses, showing significantly reduced thromboembolism rates (p\u2009=\u20090.04), increased rates of anemia (p\u2009=\u20090.01), and increased herpes zoster infections (p\u2009=\u20090.02). Ruxolitinib outperforms BAT in PV and patients with PV\u2010resistant or intolerant to hydroxyurea, offering better hematocrit control and reducing symptomatic burden and thromboembolism risk. Yet, it is associated with higher rates of anemia, herpes infection, and skin cancer.<\/jats:p>","DOI":"10.1111\/apm.13472","type":"journal-article","created":{"date-parts":[[2024,10,8]],"date-time":"2024-10-08T17:08:01Z","timestamp":1728407281000},"page":"775-786","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Efficacy and safety of ruxolitinib vs best available therapy for polycythemia vera: An updated systematic review and meta\u2010analysis"],"prefix":"10.1111","volume":"132","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-4218-8493","authenticated-orcid":false,"given":"M.
