METÁSTASIS HEPÁTICAS DE ORIGEN COLORRECTAL SINCRÓNICAS: ¿INTERVENCIÓN SIMULTÁNEA O SECUENCIAL?

Abstract

Background: Synchronous liver metastases of colon cancer can be managed with sequential or simultaneous surgical management of the primary tumor and the metastases. Aim: To compare the evolution of patients whose liver metastases were treated sequentially or simultaneously. Material and Methods: Retrospective analysis of 76 patients aged 63 ± 11 years (67% males). In 25, metastases were managed simultaneously and in 51 there were treated sequentially after a period of chemotherapy. All interventions were performed by the same surgeon. Results: Patients treated sequentially had a higher number of metastases and more lymph nodes involved than their counterparts treated simultaneously. The overall resectability index was 78%. Eighteen major and 28 minor hepatic resections were carried out. Significantly more major resections were carried out in the sequential treatment group. Mean hospital stay was 11 days and 20% of patients had complications, with no differences between groups. Survival at one, three and five years was 75, 45 and 36% in the simultaneous treatment and 76, 49 and 29% in the sequential treatment group (with no significant differences between groups). Conclusions: In this group of patients no differences in complications or survival were observed when liver metastases were treated simultaneously or sequentially. However groups were not homogeneous.
