The antitumoral effect of gamma-Interferon (Re-IFN-gamma, KW-2202) on nine patients with hepatocellular carcinoma (HCC) has been investigated. gamma-IFN was administered intravenously biweekly at a dose of 8-24 x 10(6) units/day for 5 consecutive days. As all patients had measurable disease determined by an abdominal CT, the antitumoral effect was evaluated by CT, according to the criteria of Koyama and Saito, During gamma-IFN therapy, one patient, who received a total of 4.4 x 10(8) units of gamma-IFN, achieved a partial response (PR) 133 days after onset of treatment. Another patient showed a minor response (MR) 43 days after start of therapy. The duration of the PR and MR were 7.8 weeks and 10.8 weeks, respectively. Two patients were assessed as having had no change (NC), and 5 patients as still manifesting a progressive disease (PD). Marked falls in serum alpha-fetoprotein levels during therapy were observed in 2 cases of which one was graded as having obtained a PR, and the other, a NC. The toxicities observed were fever, general malaise, headaches, and joint pains, which were slight and transient in most cases. In one case, however, a therapy was stopped because of a continuous and severe shoulder pain with no metastasis. Further studies on the use of IFN, possibly in combination with other chemotherapeutic agents, should be performed in patients with HCC.

Although primary hepatocellular carcinoma is uncommon, metastasis to the upper extremity as a presenting symptom is even more rare. Recent case reports and autopsy surveys document that extrahepatic spread of this carcinoma occurs in 30% to 78% of patients, who usually are without regional symptoms involving bone. Although metastatic spread to the lungs and lymph nodes occurs more commonly, the incidence of bone metastases has increased according to previous reports and is now estimated from 2% to 13%. This case report concerns widely disseminated hepatocellular carcinoma presenting initially without any other systemic signs except for shoulder pain and induration. Due to the aggressive nature of this tumor, early detection is crucial. Early diagnosis may offer the only real hope for establishing effective treatment and improving the chances for long-term survival.

Hepatocellular carcinoma (HCC) is the most common primary tumor of the liver and is the fifth most common cancer in the world; its incidence has been increasing in recent years. Extrahepatic spread is present at the time of diagnosis in only about 5 to 15% of patients. Skeletal metastasis of HCC occurs less frequently compared with other cancers and is considered a rare primary form of presentation. We report two cases of unsuspected HCC presenting with multiple bone lesions as the initial presentation. The first patient was a 76-year-old man with symptoms of fatigue and back pain. The PET-CT revealed the hypercaptant bone lesions and a liver lesion. The pathology report showed that the metastases were positive for the hepatic marker HEPAR-1, indicating that they had originated from the HCC. The second patient was a 56-year-old man. He presented to the emergency department for right shoulder pain and weakness of the entire right arm with no history of trauma. During hospitalization, the patient became quadriplegic. MRI revealed osseous blastic lesions in the cervical vertebrae and right shoulder. A CT-guided biopsy was performed in the cervical lesion and showed poorly differentiated carcinoma. Immunohistochemistry staining was positive for HEPAR-1. In conclusion, this cases show an unusual presentation of HCC with skeletal metastasis.
