OBJECTIVE
To elucidate the usefulness of monitoring Lens culinaris agglutinin-reactive alpha-fetoprotein (AFP-L3) and des-gamma-carboxy prothrombin detected with a revised kit (DCP-R) as clues to the diagnosis of recurrent hepatocellular carcinoma (HCC).
METHODS
A total of 57 patients with HCC were enrolled in the study. They were classified into two groups: group A comprised 27 patients in whom the diagnostic clue to recurrent HCC appeared before November 1997; these patients were monitored by ultrasonography, computed tomography (CT), AFP and des-gamma-carboxy prothrombin detected with a conventional kit (DCP-C). Group B comprised 30 patients in whom the diagnostic clue to recurrent HCC was detected after November 1997; these patients were monitored by ultrasound, CT, AFP, AFP-L3 and DCP-R.
RESULTS
In group A, 22 and five HCC recurrences were recognized initially by imaging studies and tumour markers, respectively. In group B, 17 and 13 HCC recurrences were recognized initially by imaging studies and tumour markers, respectively. The number of patients in whom tumour markers were the first clue to the diagnosis of recurrent HCC was significantly higher in group B than in group A.
CONCLUSIONS
Periodic examination of AFP-L3 and DCP-R may be useful for the early detection of recurrent HCC.
