Abstract 170P
Background
Fibrolamellar hepatocellular carcinoma (FL-HCC) is a rare primary hepatic malignancy considered to be a variant of hepatocellular carcinoma. It accounts for about ≈ 1-5% of all HCCs .Surgery (resection/liver transplantation) is the current standard treatment and remains the only potentially curative treatment option ; however, the role of chemotherapy is still controversial . Therefore, we conducted this study to evaluate the efficacy of chemotherapy in improving the survival of patients with Fibrolamellar hepatocellular carcinoma (FL-HCC).
Methods
Using SEER database, we extracted the data of 100 patients with FL-HCC from 2004 to 2014. There were 40 (40%) patients underwent surgery combined with chemotherapy, while 60(60%) of them received chemotherapy only. Patients’ demographics and staging system were assessed.
Results
Patients with FL-HCC had better outcomes when they received surgery alone compared to those who received surgery combined with chemotherapy, where overall 1-year relative survival rates were 98.3% and 95%, respectively (significant p value of 0.031).Subgroup analysis revealed that there is a highly significant P-value (< 0.0001) regarding both different age groups and staging system. On the other hand ;there is No significance for the p value was reported to the race or sex.Table:

Conclusions
surgery alone without chemotherapy in patients with FL-HCC shows higher 1-year relative survival rates when compared to surgery combined with chemotherapy. So, we recommend surgery alone without chemotherapy as a superior modality for better survival. Further studies should be conducted on a larger number of patients to confirm the results.
