| Popis: | 15071 Background: Fibrolamellar hepatocellular carcinoma (FL-HCC) is a rare subtype of primary HCC which often arises in young patients without underlying hepatic disease or viral infection. Clinical and pathological factors of prognosis are warranted. Methods: Descriptive, univariate and multivariate analysis of survival parameters were analyzed in a monocenter cohort of FL-HCC patients completely resected. Main variables were WHO-PS, age, AJCC stage, AFP level and detailed pathological features including EGFR, p- AKT, and PTEN expression. Results: 23 consecutive patients (median age: 30, M/F:6/17) with pathologically reviewed FL-HCC were analyzed. Median tumor size was 11 cm (range 4–23) and 6 patients had AFP>200ng/ml. two patients had respectable metastasis (lung or peritoneum), 5 patients had vascular invasion and 3 patients had lymph node metastasis achieving the following AJCC staging: I (70%), III (22%) and IV (8%). With median follow-up of 36 months, 3-year survival was 76% . Median time of recurrence was 23 months. Sites of first recurrence were hepatic in 5 patients, extra-hepatic in 4 patients, and both in 3 of 12 patients who recurred (52%). Metastasis occurred in lung, peritoneum, bone, skin and lymph nodes. Expression of EGFR, p-AKT, and PTEN was found in 94%, 69% and 0% of patients, respectively. None of the clinical parameters including AJCC staging predicted survival. In multivariate analysis, bad prognostic factors of recurrence were satellite micro-nodules (p=0.04) and micro-vascular tumor invasion (p=0.03) on pathological specimens. There was a trend toward a better survival in patients with No significant financial relationships to disclose. |
