Surgical treatment of liver metastases from colorectal cancer in elderly patients

Introduction The liver is the most frequent site of liver metastases (LM) from colorectal cancer. Because of short life expectances and improved nonoperative modalities, the role of liver resection in elderly patients with LM is unclear.Methods During a 15-year period, 197 patients underwent liver resection for colorectal metastases. This study was designed to compare morbidity, mortality, and long-term outcome after hepatic resection in patients aged 70 years and older and in patients younger than 70. According to the age at the time of operation, patients were divided into two groups. Group A included patients aged 70 years or older and group B included younger patients.Results The clinical and pathologic parameters of the two groups were compared and tested as factors affecting early and long-term outcomes after resection. A modified oncologic clinical risk score (CRS) was tested on this series of patients. Overall morbidity was 16.3% (group A 20.7% vs group B 14.6%; P=0.18). Hospital mortality was 3% (5.7% in group A and 2.1% in group B; P=0.19). Actuarial 5 years survival were 30% in group A and 38% in group B (P=ns).Discussion The presence of more than three Fong’s CRS parameters and microscopic involvement of resectional margin directly affected survival. Under meticulous preoperative assessment and postoperative care, liver resection for LM is justified in patients over 70 years of age; age by itself may not be a controindication to surgery.
