Large databases of consecutive patients followed for sufficiently long periods are needed to establish the rates, chronology, and hierarchy of complications of cirrhosis as well as the importance of other potential causes of liver disease. In accordance with this goal, a cohort of patients with compensated cirrhosis due to hepatitis C virus (HCV) was followed for 17 years. Two hundred and fourteen HCV RNA-seropositive patients with Child-Pugh class A cirrhosis who had no previous clinical decompensation were prospectively recruited and followed up with periodic clinical and abdominal ultrasound examinations. During 114 months (range 1-199), hepatocellular carcinoma (HCC) developed in 68 (32%), ascites in 50 (23%), jaundice in 36 (17%), upper gastrointestinal bleeding in 13 (6%), and encephalopathy in 2 (1%), with annual incidence rates of 3.9%, 2.9%, 2.0%, 0.7%, and 0.1%, respectively. Clinical status remained unchanged in 154 (72%) and progressed to Child-Pugh class B in 45 (21%) and class C in 15 (7%). HCC was the main cause of death (44%) and the first complication to develop in 58 (27%) patients, followed by ascites in 29 (14%), jaundice in 20 (9%), and upper gastrointestinal bleeding in 3 (1%). The annual mortality rate was 4.0% per year and was higher in patients with other potential causes of liver disease than in those without them (5.7% vs. 3.6%; P ‫؍‬ .04). In conclusion, hepatitis C-related cirrhosis is a slowly progressive disease that may be accelerated by other potential causes of liver disease. HCC was the first complication to develop and the dominant cause for increased mortality.

To see whether or not there is an association between the cause of cirrhosis and the number of hepatocellular carcinoma (HCC) nodules, we analyzed 178 consecutive patients in whom HCC was detected during a prospective screening by abdominal ultrasound (US). The relevant information was obtained from the database of the screening programs operating at four hospitals in the Milan area. One hundred twenty-nine (72%) patients had a single tumor nodule detected by US and 49 (28%) patients had multinodular disease. Ninety-eight (55%) patients had normal serum values of ␣-fetoprotein (AFP). Tumor staging with biphasic computed tomography (CT) scan or hepatic arteriography with lipiodol revealed that 101 (57%) patients had single tumor nodules and 77 (43%) patients had more than one HCC nodule. After staging, multinodular HCC was more common in patients with multiple risk factors than in the hepatitis C virus (HCV) carriers (56% vs. 38%, P ‫؍‬ .05). Interestingly, single tumors were as common in the 126 patients undergoing 6-month interval screening as in the 52 patients who were studied at yearly intervals. The former patients, however, had more small tumors than the latter ones (91% vs. 74%, P ϭ .04). The 22 patients who were alcohol abusers had normal levels of serum AFP more often than the hepatitis B virus (HBV) or HCV carriers or those with multiple risk factors (86% vs. 57%, P F .04; vs. 47%, P F .002; vs. 52%, P F .006, respectively). We concluded that multinodular HCC was underdetected by real time US; it prevailed among patients with multiple risk factors. In these patients, screening with US exams every 6 months may be inadequate for early detection of liver cancer. (HEPATOLOGY 1999;29:1704-1707.)

CONCLUSIONS: precontrast CT acquisition did not provide significant information in trauma patients, exposing them to an unjustified radiation dose.
