Resection of hepatocellular carcinoma: the effect of surgical margin and blood transfusion on long-term survival. Analysis of 209 consecutive patients.

摘要

BACKGROUND/AIMS: Certain prognostic factors affect the postoperative mortality and long-term survival of patients following hepatic resection for hepatocellular carcinoma (HCC) and may change the surgical strategy. METHODOLOGY: 209 consecutive patients underwent hepatic resection for HCC in our hospital. Seventy-three patients underwent major resection and 136 underwent minor resections. We looked for correlations between clinical, biological, surgical and pathological factors and postoperative mortality, disease-free survival and overall survival. RESULTS: The postoperative mortality rate was 7.7% (it fell to 0% in the last two years). The cumulative overall five-year survival rate was 27% and the overall disease-free survival rate was 7.3%. Multivariate analysis identified: (1) two independent prognostic factors for postoperative mortality: age and tumor size; (2) one risk factor for tumor recurrence: intraoperative blood transfusion, and (3) three independent prognostic factors for overall survival:infiltrative tumor type, surgical margin <10 mm and intraoperative blood transfusion. CONCLUSIONS: In addition to routine staging of the tumor, the preoperative evaluation of HCC patients should include tests to determine whether the tumor is infiltrative or expansive and whether it will be possible to obtain a surgical margin (>10 mm). This procedure should make it possible to propose an appropriate neoadjuvant treatment only to these patients. The prevention of intraoperative bleeding or blood transfusion should improve the disease-free and overall survival rates in HCC patients.
