Purpose:Our aim was to assess rate of recurrence and long-term survival in patients undergoing LDLT and deceased donor (DDLT) liver transplantation for HCC and to identify prognostic indicators for tumor recurrence.
Methods:The records of 104 patients who had undergone liver transplantation (LT) for HCC from 1999-2007 were reviewed. Twenty-eight patients underwent LDLT and 76 underwent DDLT. Mean age, MELD scores, median tumor size, and macrovascular invasion were compared.
Results:

	Age	MELD	Recurrence*	Tumor size*
DDLT	55.1±0.78	13.2±0.8	9.2%	2.7±1.7
LDLT	56±1.1	11.2±1.2	28.6%	3.3±1.3

*(p<0.05)
While macrovascular invasion was not associated with recurrence in the DDLT group (p=0.11), it was significantly associated with recurrence in the LDLT group (p=0.017).The difference in overall survival between the two groups was not statistically significant (Fig. 1, p=0.058). The survival of DDLT(n=69) and LDLT(n=20) patients who did not have recurrence at 6 years was 62.3% and 100% respectively (Fig.2, p=0.013).
Conclusion: 1)Despite increased median tumor size, presence of macrovascular invasion and tumor recurrence in patients undergoing LDLT, 3 and 6-year survival was not different from DDLT. 2)LDLT in patients with HCC offers superior survival in those without recurrence and a trend (p=0.058) for improved overall survival compared to DDLT. 3) Concerns regarding increased mortality in patients undergoing LDLT for HCC appear unwarranted.
