Abstract
OBJECTIVE: The aim of this study was to determine the safety of elderly cancer patients (≥70 years) undergoing hepatic resection (HR) or pancreaticoduodenectomy (PD) in comparison with younger adults (<70 years). METHODS: A total of 1,012 consecutive patients undergoing HR or PD were included. The incidence and severity of morbidity were documented within 30 days postoperatively and compared between elderly and younger groups. Risk factors associated with postoperative morbidity were investigated by multivariate logistic regression analysis. RESULTS: Elderly patients (n=111, 11.0%) had more comorbidities and worse preoperative general condition and liver function versus younger patients (n=901, 89.0%), and thus were more likely to develop infectious (eg, systemic sepsis and urinary tract infection, both p<0.01) and technical-associated complications (intraperitoneal bleeding and biliary/pancreatic fistula, p=0.029 and p=0.074, respectively). However, the incidence and severity of complications were comparable between elderly and younger patients in the whole cohort, and also in HR and PD surgery groups separately. Preoperative hemoglobin (odds ratio [OR] 1.4, p=0.007) and intraoperative blood transfusion (OR 1.9, p=0.002), rather than age, were independently associated with postoperative morbidity. Hepatitis (OR 2.9, p=0.001), preoperative hemoglobin (OR 1.6, p=0.036), and pancreatic versus hepatic surgery (OR 2.3, p=0.005) were independently associated with postoperative infectious. For elderly patients only, American Society of Anesthesiologists (ASA) score III (OR 2.1, p=0.033) and intraoperative blood transfusion (OR 3.2, p=0.030) were independently associated with postoperative morbidity. CONCLUSION: HR and PD can be safely performed in selected elderly patients versus younger patients. Elderly patients with ASA score III or above should be cautiously selected for major surgeries.
