Major Hepatectomy for Colorectal Liver Metastases in Patients Aged Over 80: A Propensity Score Matching Analysis




The aim of this study was to evaluate the results of major hepatectomies for metastasis in elderly colorectal cancer patients, for whom limited data exist in the literature.


From January 2006 to January 2013, 3,034 patients underwent hepatectomy for colorectal liver metastasis in 32 French surgical centers. Repeat hepatectomies were excluded from the study. Based on a 1: 4 propensity score matching model, 42 patients aged ≥80 (OG) were matched with 168 patients <80 years (YG) in order to obtain 2 well-balanced and homogeneous groups with regards to therapy and prognostic factors.


The unmatched cohort consisted of 744 patients (OG: n = 42; YG: n = 702). After PS matching, there was no difference in terms of general morbidity, rates of Dindo-Clavien score ≥III (OG: 16% vs. YG: 21%, p = 0.663), surgical morbidity (OG: 16% vs. YG: 21%, p = 0.663), reoperation (OG:10% vs. YG: 5%, p = 0.263), 90-day mortality (OG: 0% vs. YG:2%, p = 1), and total median hospital stay (OG: 12 vs. YG: 12, p = 0.972). Both groups experienced similar 3- and 5-year overall survival (82 and 82% OG vs.78 and 67% YG) and disease-free survival (40 and 35% OG vs. 45 and 35% YG at 3 and 5 years).


No difference in perioperative and postoperative outcomes and disease-free and overall survival was found. Major hepatectomy in selected octogenarian patients is safe and feasible.
