RESUMO
The rapidly aging population in industrialized countries comes with an increased incidence of intrahepatic cholangiocarcinoma (iCC) which presents new challenges for oncological treatments especially in elderly patients. Thus, the question arises to what extent the benefit of surgical resections, as the only curative treatment option, outweighs possible perioperative risks in patients ≥ 80 years of age (octogenarians). We therefore retrospectively analyzed 311 patients who underwent resection for iCC at Hannover Medical School between January 1996 and December 2022. In total, there were 11 patients older than 80 years in our collective. Despite similar tumor size, octogenarians underwent comparatively less extensive surgery (54.5% major resections in octogenarians vs. 82.7% in all other patients; p = 0.033) with comparable rates of lymphadenectomy and tumor-free resection margins. Furthermore, we did not observe increased major postoperative morbidity (Clavien-Dindo ≥ IIIa complications: 27.3% vs. 34.3% in all other patients; p = 0.754) or mortality (estimated 1-year OS of 70.7% vs. 72.5% in all other patients, p = 0.099). The length of intensive care unit (ICU) or intermediate care unit (IMC) stay was significantly longer in octogenarians, however, with a comparable length in total hospital stay. The estimated overall survival (OS) did also not differ significantly, although a trend towards reduced long-term survival was observed (14.5 months vs. 28.03 months in all other patients; p = 0.099). In conclusion, primary resection is a justifiable and safe therapeutic option even in octogenarians but requires an even more thorough preoperative patient selection.
