BACKGROUND: With the progress in early clinical treat- ment of hepatocellular carcinoma (HCC), early detection and diagnosis of HCC have been increasingly pressing. Combined alpha-fetoprotein ( AFP) determination and ul- trasonography has become the main method for the detec- tion of small HCC; but the relationship between low eleva- tion of AFP and pathologic findings of small HCC has not been well defined. The aim of this study was to assess the value of ultrasound-guided fine needle biopsy of intrahe- patic nodules and low elevation of serum AFP in the early diagnosis of HCC. METHODS; Fifty-nine patients with serum AFP exceeding 20 ng/ml and intrahepatic nodules varying from 0.8 cm to 5.0 cm in diameter who had been detected by ultrasonogra- phy underwent ultrasound-guided percutaneous fine needle biopsy, and cytological staining and histological sectioning were performed at the same time. RESULTS: Among the 59 patients, 11 patients (18.6%) showed AFP level above 400 ng/ml, 5 (8. 5%) from 200 ng/ml to 400 ng/ml, 18 (30. 5%) from 50 ng/ml to 200 ng/ml and 25 (42. 4% ) from 20 ng/ml to 50 ng/ml. Fol- low-up demonstrated that 53 patients (89.8%) had a pro- gressive increase of AFP level. In 58 patients (98.3%) cancer cells were found by cytological staining and/or his- tological sectioning. CONCLUSIONS: In those patients with slightly increased or continuously positive AFP, hepatic carcinoma should be highly suspected when AFP increases gradually and intrahe- patic nodules are detected by ultrasonography in follow-up. Once intrahepatic carcinoma nodules are suspected, ultra- sound-guided fine needle biopsy should be performed as early as possible for early diagnosis and treatment.
