BACKGROUND/AIMS: Advanced hepatocellular carcinoma (HCC) with multiple lung metastases has a poor prognosis with no effective treatment having been established. This study evaluated the outcomes of systemic chemotherapy for advanced HCC with multiple lung metastases. METHODS: Between January 2000 and December 2006, 68 patients were diagnosed with HCC presenting with multiple lung metastases. Sixteen patients in the terminal stage, such as Child-Pugh grade `C' or an Eastern Cooperative Oncology Group performance status exceeding grade 2, were excluded from the analysis. The following treatment modalities were applied: 26 patients received primary tumor treatment (transarterial chemoembolization or intra-arterial chemotherapy) with systemic chemotherapy, 10 patients received primary treatment only, 8 patients received systemic chemotherapy only, and 8 patients received highly supportive care. The treatment responses and median survival times for the modalities were analyzed and compared. RESULTS: The median age of the 52 analyzed patients (45 males) was 52.4 years. The most common etiology of HCC was chronic hepatitis B virus infection (n=44, 84.6%) followed by hepatitis C virus infection (n=2, 3.8%), with the etiology being unknown in 6 cases (11.5%). The treatment modality had no significant effect on the treatment response rate (P=0.432) or median survival time (133, 66, 74, and 96 days for primary tumor treatment with systemic chemotherapy, primary tumor treatment only, systemic chemotherapy only, and highly supportive care, respectively; P=0.067). CONCLUSIONS: We found that systemic chemotherapy was not effective in treating HCC presenting with multiple lung metastases. Improving the effectiveness of systemic treatment and selecting patients who would benefit from such treatment remains a major challenge.

Transcatheter arterial chemoembolization (TACE) has been used widely to treat patients with unresectable hepatocellular carcinoma. However, this method can induce various adverse events caused by necrosis of the tumor itself or damage to nontumor tissues. In particular, neurologic side effects such as cerebral infarction and paraplegia, although rare, may cause severe sequelae and permanent disability. Detailed information regarding the treatment process and prognosis associated with this procedure is not yet available. We experienced a case of paraplegia that occurred after conducting TACE through the intercostal artery to treat hepatocellular carcinoma that had metastasized to the rib. In this case, TACE was attempted to relieve severe bone pain, which had persisted even after palliative radiotherapy. A sudden impairment of sensory and motor functions after TACE developed in the trunk below the level of the sternum and in both lower extremities. The patient subsequently received steroid pulse therapy along with supportive care and continuous rehabilitation. At the time of discharge the patient had recovered sufficiently to enable him to walk by himself, although some paresthesia and spasticity remained.

Transarterial chemoembolization (TACE) is one of the most effective therapies for unresectable hepatocelluar carcinoma or metastatic hypervascular tumors. Abscess occurring in the other organs beside the liver after TACE is a complication that often occurs, sometimes potentially fatal. We report a case of spinal epidural abscess occurred after liver abscess complicated by TACE in a patient with metastatic neuroendocrine tumors to the liver. A 67-year-old female underwent TACE first for the metastatic lesions to liver, with a history of pancreatoduodenectomy for the primary pancreatic neuroendocrine tumor. Four days after TACE, sudden high fever occurred, and liver abscess was found on abdominal CT. Two days later, back pain and radiating pain to the right leg occurred, and lumbar spine MRI showed spinal epidural abscess. After intravenous antibiotics for 8 weeks and partial laminectomy, the patient recovered and was discharged without complications.
