Multi-institutional analysis of recurrence and survival after hepatectomy for fibrolamellar carcinoma.

ABSTRACT

BACKGROUND AND OBJECTIVES: Fibrolamellar carcinoma (FLC) presents in young, otherwise-healthy individuals. This study examined recurrence and survival characteristics after surgical resection for FLC by utilizing an international multi-institutional database. METHODS: Consecutive patients undergoing hepatectomy for FLC from six institutions (1993-2010) were reviewed retrospectively. Survival was studied with life tables and Cox regression models. RESULTS: Thirty-five patients (13 female, 37%) were included (median age 32 years). R0 resection was achieved in all curative-intent operations (n = 30), and palliative operations were performed for five patients. Crude 30-day morbidity and mortality rates were 22% and 3%, respectively. For curative-intent surgery, overall and recurrence-free survivals at 5 years were 62% and 45%, respectively. In patients who achieved a 4-year disease-free interval after surgery, none subsequently developed recurrence. In multivariate models, presence of extrahepatic disease was the only factor that independently predicted overall (hazard ratio [HR] 5.58, 95% confidence interval [CI] 1.38-22.55, P = 0.016) and recurrence-free survival (HR 5.64, 95% CI 1.48-21.49, P = 0.011). CONCLUSIONS: Patients with surgically amenable FLC had encouraging long-term survival. Recurrence-free survival to 4 years suggested possible freedom from disease thereafter. Recurrent resectable disease was associated with an excellent prognosis, and repeat surgery should be strongly considered.
