lected HCC are similar to the results in cirrhotic patients Cumulative recurrence after surgical resection for hewithout tumor. (HEPATOLOGY 1997;25:1485-1489.) patocellular carcinoma (HCC) is very high. Several retrospective analyses have shown that liver transplantation was more effective than resection for patients with Hepatocellular carcinoma (HCC) usually occurs with the HCC at early tumor stages. Consequently, in January presence of cirrhosis and is considered to have a poor progno-1990, we decided to prospectively indicate orthotopic sis.1 To the present, surgical resection has been the treatment liver transplantation (OLT) as the first surgical treat-of choice whenever feasible.2 However, the resection rate rement for small, localized HCC in cirrhotic patients with-mains low in cirrhotic patients. 3,4 In the last few years, some out nodal involvement independently of the degree of groups have reported disappointing long-term results after liver function. The aim of this prospective cohort study resection of small tumors in cirrhotic patients. The 5-year was to analyze prognosis, recurrence rate, and survival recurrence rate is very high, 74% among 386 patients acafter liver transplantation in patients in whom the main cording to Makuuchi, 5 and 100% in Belghiti's series. 6 Other indication was HCC with cirrhosis. Thirty-eight patients authors have accepted orthotopic liver transplantation (OLT) in whom the main indication for liver transplantation as a treatment indication in patients with advanced tumors was HCC and hepatic cirrhosis were compared with 136 or with associated end-stage liver disease.7-11 Moreover, sevtransplantations because of cirrhosis without tumor, eral retrospective analyses have recently shown that OLT performed in our unit from January 1990 to December was more effective than liver resection for patients with HCC 1995.

Chemoembolization using doxorubicin, lipiodol, have led to a restricted indication of liver transplantation for and Gelfoam was performed before OLT in 31 patients HCC.12-14 On the other hand, the absence of recurrence after with good liver function. There were no differences in transplantation for incidental HCC prompted us to look for gender, but HCC patients were older (57 { 7 vs. 50 { 10 favorable preoperative staging criteria for small HCC in ciryears [P õ .001]).

To assess the presence of MSI in colorectal cancer, we have developed a simple, sensitive, and specific approach based on the apparent good fit of the data to a two-population model. Its application to a prospective series of patients with colorectal carcinomas demonstrates that the presence of MSI characterizes a subset of less aggressive tumors.
