BACKGROUND: The study of patients with hepatocellular carcinoma (HCC) and multiple primary malignant tumors (MPMTs) is interesting from an etiopathogenetic as well as from a clinical point of view. There are few studies dealing with this topic. METHODS: Smoking habits, alcohol intake, HBsAg status, alpha-feto-protein serum concentration, presence of liver cirrhosis, type of associated cancers, treatment, and survival were evaluated in 29 patients (25 men and 4 women; median age 73 years) with histologically confirmed HCC and MPMTs. All patients were examined between January 1980 and February 1995 at the General Hospital of Monfalcone, in northeastern Italy. In the same period there were 143 patients with HCC. RESULTS: Tumors associated with HCC were located in: prostate (9 cases), colon-rectum (5), bladder (3), lung (3), stomach (2), gallbladder (2), and brain, breast, oesophagus, pancreas, thyroid, larynx, pleura, small intestine, kidney (1 each). In 25 patients there was a single, and in 4 patients two associated malignancies. A diagnosis in vita of the associated malignancy was made in 15 cases. Cirrhosis was present in 90% of patients and HBsAg was positive in 15%. Mean survival time from diagnosis was 5.5 weeks (0-150) in patients with MPMTs and 6.8 weeks (0-221) in patients with HCC only. The cause of death was HCC in 18 patients, the associated tumor in 8, and non-neoplastic diseases in 2. Treatment of the associated tumors was performed in 8 cases. CONCLUSIONS: In this study the prevalence of MPMTs in patients with HCC is high (20.3%) in accordance with other autopsy series. Mean survival time in patients with MPMTs was similar to that in patients with HCC only. From a clinical point of view, attention must be paid to the diagnosis of hepatic lesions in patients affected with cirrhosis and extrahepatic cancer.
