We performed a systematic review and meta-analysis of 83 studies (604,853 patients) assessing the overall hazard associated with liver metastases by primary tumor type and treatment regimen. The pooled overall survival hazard ratio (HR) for all included studies was 1.77 (95% confidence interval [CI], 1.62\u20131.93). Patients with breast cancer primaries fared the worst (HR, 2.37; 95% CI, 1.64\u20133.44), as did patients treated with immunotherapies (HR, 1.86; 95% CI, 1.42\u20132.42).
