Major hepatectomies can be safely performed at the same time as colorectal surgery in selected patients with synchronous metastases with similar short-term results, even in the presence of rectal cancer.
Liver resection for colorectal liver metastases may be curative in more than one-third of patients without negative prognostic factors. Postoperative morbidity significantly worsens long-term outcomes. The risk of recurrence after liver resection is high even after 5 years of follow-up, but re-resection can improve the outcome.
In recent decades liver resection has become a safe procedure; however, the outcome of hepatectomies in aged cirrhotic patients is often uncertain. To elucidate early and long-term outcomes of hepatectomy for HCC in the elderly, we studied 241 cirrhotic patients who underwent liver resection for HCC between 1985 and 2003. According to their age at the time of surgery, patients were divided into two groups: aged > 70 years (64 patients) and aged < or = 70 years (177 patients). Operative mortality was 3.1% in the elderly and 9.6% in the younger group (p = 0.113). Postoperative morbidity and liver failure rates were higher in the younger group (42.4% versus 23.4%, p = 0.0073; 12.9% versus l.6%, p = 0.0065). Five-year survival rates are 48.6% in the elderly group and 32.3% in the younger group (p = 0.081). Considering only radical resections in Child-Pugh A patients, survival remains similar in the two groups (p = 0.072). Disease-free survival is not different in the two groups. A survival analysis performed according to the tumor diameter shows a better survival for elderly Child-Pugh A patients with HCC larger than 5 cm radically resected (50.8% versus 16.1% 5-year survival, p = 0.034). In univariate analysis, tumor size is not a prognostic factor in the elderly, whereas younger patients with large tumors have a worse outcome. Age by itself is not a contraindication for surgery, and selected cirrhotic patients with HCC who are 70 years of age or older could benefit from resection, even in the presence of large tumors. Long-term results of liver resections for HCC in the elderly may be even better than in younger patients.
Additional resection of a positive proximal (BD(Marg)) , albeit associated with an increased risk of biliary fistula, offers a significant survival benefit and should be attempted whenever possible.
Overall mortality and morbidity after liver resection are not improved by preoperative biliary drainage in jaundiced patients. Prehepatectomy biliary drainage increases the incidence of infectious complications.
Patients with liver metastases synchronous with colorectal cancer with T4 primary tumor, metastasis infiltration of neighboring structures, and especially with more than three metastases should receive neoadjuvant chemotherapy before liver resection.
Systematic US exploration of the liver leads to increase the intraoperative detection rate of DLMs. Furthermore, the majority of DLMs identified by IOUS presents residual disease at pathological examination and should be treated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
