However, the role of hepatectomy for non-colorectal liver metastasis (NCLM) is less clear. PATIENTS AND METHOD: From 2004 to 2017, 264 patients received curative hepatectomy for NCLM (n = 28) and CLM (n = 236). Propensity score (PS) matching was performed between two groups, with respect to the significant confounding factors. Short-term and long-term outcomes were compared between PS matched groups. Univariate analysis was performed to identify prognostic factors affecting overall and recurrence-free survival. RESULTS: After PS matching, there were 28 patients in NCLM group and 56 patients in CLM group. With a median follow-up of 34 months, there was no significant difference in 5-year overall survival rate between NCLM and CLM groups (62% vs. 39%) (P = 0.370). The 5-year recurrence-free survival rate was also comparable between NCLM and CLM groups (23% vs. 22%) (P = 0.707). Use of pre-operative systemic therapy (hazard ratio: 2.335, CI 1.157-4.712), multifocal tumors (hazard ratio: 1.777, CI 1.010-3.127), tumor size (hazard ratio: 1.135, CI 1.012-1.273), R1 resection (hazard ratio: 2.484, CI 1.194-5.169) and severe complications (hazard ratio: 6.507, CI 1.454-29.124), but not tumor type (NCLM vs. CLM), were associated with poor overall survival. CONCLUSION: Hepatectomy for NCLM can achieve similar oncological outcomes in selected patients as those with CLM. Significant prognostic factors were identified associating with worse overall survival.","is_dataset_classified":null,"base_score":2.1972245773362196,"endowment":2.1972245773362196,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"33229125","pmcid":null,"openalex_id":"https://openalex.org/W3109393922","authors":[],"funders":[{"funder_name":"Chinese University of Hong Kong","grant_id":"","title":null},{"funder_name":"Department of Surgery","grant_id":"","title":null}],"total_grants":2,"fwci":0.9105,"citation_percentile":0.74641049,"influential_citations":0,"citation_trend":[{"year":2022,"count":3},{"year":2023,"count":5}],"oa_status":"gold","license":"cc-by-nc-nd","oa_locations":[{"url":"https://www.sciencedirect.com/science/article/pii/S1015958420303535/pdf","host_type":"journal"},{"url":"https://www.sciencedirect.com/science/article/pii/S1015958420303535/pdf","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S1015958420303535?httpAccept=text/xml","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S1015958420303535?httpAccept=text/plain","host_type":"publisher"},{"url":"https://doi.org/10.1016/j.asjsur.2020.10.019","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/33229125","host_type":"repository"},{"url":"https://doaj.org/article/159b5c5f65f341f5a28c8d028655d6d4","host_type":"repository"}],"fields_of_study":["Hepatocellular Carcinoma Treatment and Prognosis","Intraperitoneal and Appendiceal Malignancies","Cholangiocarcinoma and Gallbladder Cancer Studies","Colorectal Neoplasms","Hepatectomy","Humans","Liver Neoplasms","Prognosis","Propensity Score","Retrospective Studies","Survival Rate","Treatment Outcome"],"mesh_terms":["Hepatectomy","Humans","Liver Neoplasms","Prognosis","Retrospective Studies","Colorectal Neoplasms","Survival Rate","Treatment Outcome","Propensity Score"],"keywords":["Medicine","Propensity score matching","Hazard ratio","Hepatectomy","Internal medicine","Colorectal cancer","Proportional hazards model","Confounding","Univariate analysis","Metastasis","Oncology","Gastroenterology","Survival rate","Multivariate analysis","Confidence interval","Surgery","Resection","Cancer","Liver","Metastases","Outcome","Non-colorectal"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Good health and well-being"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-02T23:00:32.514695Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
