Abstract
To anticipate the prognosis and choose therapy for patients with relatively early-stage HCCs, we elucidate the natural course of such patients. Thirty cirrhotic patients with small hepatocellular carcinoma (HCC) < 3 cm in size and not receiving anti-cancer treatment were followed by sonography for periods of 6-48 mots. The growth speed varied considerably from case to case, with an average of 6.5+/-5.7 months of doubling time (DT). Growth speed of small HCC is significantly related to histological differentiation of tumors: a slow-growing HCC tends to be well-differentiated and a rapid-growing HCC moderately- or poorly-differentiated. Furthermore, there was a tendency to grow without changing from nodular type in slow-growing HCCs and to multiple nodular or massive types in intermediate- and rapid-growing HCCs. The survival rates of these untreated HCC patients showed a 1-yr survival of 90.7%, a 2-yr survival of 55.0%, and a 3-yr survival of 12.8%. Factors significantly influencing survival of these patients were serum total bilirubin level and DT. This study will provide invaluable data for diagnosing and treating for small HCCs.
