We investigated whether or not a high serum alanine aminotransferase (ALT) level is associated with a more rapid recurrence of hepatocellular carcinoma (HCC) in hepatectomized patients with hepatitis C virus (HCV)-associated liver cirrhosis (LC) (HCV-LC) and HCC. Thirty-three hepatectomized patients with HCV-LC and HCC of a single nodule who had no histologic evidence of portal or hepatic vein invasion and who had been followed up for more than 3 years were included in the study. They were subdivided into two groups according to their serum ALT levels, ALT being a well-known marker of inflammatory necrosis in the liver. Seventeen patients whose serum ALT levels showed several peaks or plateaus above 80 international units (IU) were designated as the high ALT group, and 16 patients whose serum ALT levels showed a sustained low level below 80 IU until the first recurrence were designated as the low ALT group, and the interval between hepatectomy and the first recurrence was observed. In the high ALT group, HCC recurred within 3 years in 70.6% of the patients. In contrast, it recurred in only 18.8% of the low ALT group within the same period (p < 0.05). There was a significant difference (p = 0.0201) between the two groups in the cumulative nonrecurrence rate. The mean interval in recurrent patients between hepatectomy and the first recurrence in the high ALT group (23.6 +/- 2.8 months; mean +/- SE) was significantly (p < 0.02) shorter than that in the low ALT group (49.3 +/- 9.7 months). The expected interval between hepatectomy and recurrence was as short as 2.8 +/- 0.5 years (mean +/- SE) in the high ALT group, compared with 5.8 +/- 0.7 years in the low ALT group (p < 0.05). These results showed that the recurrence of HCC was accelerated in the high ALT group, suggesting that suppression of the rise in ALT level after hepatectomy by treatment with anti-inflammatory drugs may prolong the interval until recurrence by about 2 years in hepatectomized patients with HCC and HCV-LC.
我们研究了在接受肝切除术的丙型肝炎病毒(HCV)相关肝硬化(LC)合并肝细胞癌(HCC)患者中,血清丙氨酸氨基转移酶(ALT)水平升高是否与HCC更快复发有关。本研究纳入了33例接受肝切除术的HCV-LC合并单结节HCC患者,这些患者无门静脉或肝静脉侵犯的组织学证据,且随访时间超过3年。根据血清ALT水平(ALT是肝脏炎症坏死的一个众所周知的标志物)将他们分为两组。17例血清ALT水平出现数次高于80国际单位(IU)的峰值或平台期的患者被指定为高ALT组,16例血清ALT水平在首次复发前持续低于80 IU的低水平的患者被指定为低ALT组,并观察肝切除术后至首次复发的间隔时间。在高ALT组中,70.6%的患者在3年内HCC复发。相比之下,同期低ALT组中只有18.8%的患者复发(p<0.05)。两组的累积无复发率存在显著差异(p = 0.0201)。高ALT组复发患者肝切除术后至首次复发的平均间隔时间(23.6±2.8个月;平均值±标准误)显著短于低ALT组(49.3±9.7个月)(p<0.02)。高ALT组肝切除术后至复发的预期间隔时间短至2.8±0.5年(平均值±标准误),而低ALT组为5.8±0.7年(p<0.05)。这些结果表明,高ALT组中HCC的复发加速,提示在接受肝切除术的HCC和HCV-LC患者中,通过使用抗炎药物治疗抑制肝切除术后ALT水平的升高可能会将复发间隔时间延长约2年。
