Laparoscopic major hepatectomy for colorectal liver metastases in elderly patients: a single-center, case-matched study

The incidence of colorectal cancer liver metastases (CRLM) among elderly patients has increased; therefore, older patients are increasingly being considered for hepatic resection. However, data regarding the outcome of laparoscopic major hepatectomy (LMH) in elderly patients are limited. The aim of this study was to evaluate the safety and feasibility of LMH in elderly patients with CRLM. From January 1998 to September 2013, a total of 31 patients aged a parts per thousand yen70 years (elderly group) were matched with 62 patients < 70 years (young group) by demographics, tumor characteristics, and details of surgical procedures. The elderly group was characterized by a higher incidence of hypertension (41.9 vs. 17.7 %, P = 0.022), a parts per thousand yen2 comorbidities (32.3 vs. 11.3 %, P = 0.021), and lower prevalence of metastatic rectal cancer (12.9 vs. 38.7 %, P = 0.015). Intraoperative variables, such as surgical duration (300 vs. 240 min, P = 0.920), blood loss (400 vs. 300 mL, P = 0.361), and transfusion rate (9.7 vs. 12.9 %, P = 0.726), were not notably different between the groups. Postoperative mortality (0 vs. 0 %), complications (54.8 vs. 41.9 %, P = 0.276), and major complications (27.4 vs. 16.1 %, P = 0.303, respectively) were comparable between the groups. The 3-year overall survival rates were 61.7 % in the young group (median 40 months) and 57.9 % in the elderly group (median 39 months), respectively (P = 0.842). Our results clearly demonstrated that LMH for CRLM could be safely performed in elderly patients; thus, advanced age itself should not be regarded as a contraindication for LMH.
