Liver resection is the only potential curative option; nevertheless, only 25% of the patients are considered to be eligible for surgery. To expand the potentially resectable pool of patients, surgeons developed multidisciplinary techniques like portal vein embolization, two-stage hepatectomy or associating liver partition and portal vein ligation for staged hepatectomy. Moreover, mini-invasive surgery is gaining support, since it offers lower post-operative complication rates and shorter hospital stay with no differences in long-term outcomes. In case of unresectable disease, various techniques of local ablation have been developed. Radiofrequency ablation is the most commonly used form of thermal ablation: it is widely used for unresectable patients and is trying to find its role in patients with small resectable metastasis. The identification of prognostic factors is crucial in the choice of the treatment strategy. Previous works that focused on patients with solitary colorectal liver metastasis obtained trustable negative predictive factors such as presence of lymph-node metastasis in the primary tumour, synchronous metastasis, R status, right-sided primary colon tumor, and additional presence of extrahepatic tumour lesion. Even the time factor could turn into a predictor of tumour biology as well as further clinical course, and could be helpful to discern patients with worse prognosis.<\/jats:p>","DOI":"10.1007\/s00432-021-03880-4","type":"journal-article","created":{"date-parts":[[2021,12,16]],"date-time":"2021-12-16T15:03:13Z","timestamp":1639666993000},"page":"657-665","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Solitary colorectal liver metastasis: overview of treatment strategies and role of prognostic factors"],"prefix":"10.1007","volume":"148","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9487-2197","authenticated-orcid":false,"given":"S.","family":"Acciuffi","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"F.","family":"Meyer","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"Bauschke","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R.","family":"Croner","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"U.","family":"Settmacher","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6702-0781","authenticated-orcid":false,"given":"A.","family":"Altendorf-Hofmann","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2021,12,16]]},"reference":[{"issue":"6","key":"3880_CR1","doi-asserted-by":"publisher","first-page":"818","DOI":"10.1097\/01.sla.0000128305.90650.71","volume":"239","author":"EK Abdalla","year":"2004","unstructured":"Abdalla EK, Vauthey J-N, Ellis LM, Ellis V, Pollock R, Broglio KR, Hess K, Curley SA (2004) Recurrence and outcomes following hepatic resection, radiofrequency ablation, and combined resection\/ablation for colorectal liver metastases.
