Abstract

INTRODUCTION:

Liver transplantation (OLT) has been advocated as a good management option for patients with carcinoma hepatocellular (HCC). More recurrences are extrahepatic due to many pathological factors.

PATIENTS AND METHODS:

From April 1986 to December 2003, we performed 95. OLTs for HCC including 73% men of mean age of 54.7 years and 25.3% not filling Mazzaferro's criteria.

RESULTS:

The recurrence incidence was 15.8% (n = 15), including only extrahepatic lesions in 11 (mainly lung recurrence, seven) and hepatic plus extrahepatic in four. Main late mortality was due to tumor recurrence (n = 12, 33.3%). No differences were observed among sex, preoperative chemoembolization, age, Child, Okuda, etiology, or satellite nodules. A greater incidence of tumor recurrence was observed with a preoperative biopsy (45.5% vs 5.9%, P = .0001); and alpha fetoprotein (AFP) > 200 ng/mL (37.5% vs 13.3%, P = .08); known HCC (25.5% vs 3.1%, P = .008); vascular invasion (42.1% vs 10.3%, P = .001); > 5 cm single nodule (50% vs 13%, P = .004); more than three nodules (50% vs 13.9%, P = .01); moderately to poorly differentiated tumors (37.5% vs 12.7%, P = .01); pTNM IV (50% vs 8.7%, P = .0001); and not meeting Milan criteria (40.9% vs 9.2%, P = .001). These are the same factors for extrahepatic recurrence. For hepatic recurrence the prognostic factors were: vascular invasion (15.8% vs 1.5%, P = .008), more than three nodules (25% vs 2.5%, P = .004), moderately to poorly differentiated tumors (18.8% vs 1.4%, P = .003), pTNM IV (16.7% vs 1.4%, P = .006), and not meeting Milan criteria (13.6% vs 1.5%, P = .01).

CONCLUSIONS:

Recurrence incidence with Milan criteria was less than 10%, mainly extrahepatic (lung). Prognostic factors for tumor recurrence were pathological features, namely vascular invasion, more than three nodules, size larger than 5 cm, moderately to poorly differentiated tumors, pTNM IV stage. The use of preoperative chemoembolization did not decrease the recurrence rate. A preoperative biopsy increased the incidence of extrahepatic recurrence.
