BACKGROUND: The recurrence of hepatocellular carcinoma (HCC) after surgery is common. The present study was conducted in order to clarify the significance of alpha-fetoprotein (AFP) in the detection of the early recurrence of HCC after surgery. METHODS: Fifty-eight patients who underwent a curative hepatic resection for HCC and whose preoperative AFP levels were >100 ng/ml, were selected for this study. RESULTS: In 26 cases, the postoperative AFP levels within 3 months after surgery did not decrease to 1 year after surgery. The interval from surgery to recurrence significantly correlated with the doubling time of AFP at the time of recurrence in patients with early recurrence (within 1 year after hepatectomy) (r = 0.60, P 100 ng/ml and the postoperative AFP level did not decrease to <20 ng/ml, early recurrence within 1 year after surgery would thus be strongly suspected. CONCLUSION: The measurement of the AFP levels after surgery is therefore considered to be important in the follow-up of hepatectomized patients, especially regarding the detection of early recurrence.
