A 66-year-old female patient was diagnosed with hepatocellular carcinoma accompanied by neuropathic pain induced by a metastatic tumor that compromised root and spinal canal. Although her pain was relieved following medical treatment, breakthrough pain occurring 1-2 times a day was still distressing. Neuropathic pain in her right lower limb caused discomfort and irritability and decreased her quality of life. We had limited options to adjust her prescription drug regime, due to the side effect of these drugs. Although acupuncture therapy was only performed at her home once a week, the efficacy was outstanding. The patient did not report any further instances of breakthrough pain, and she did not require additional bolus morphine. She could comfortably live in her familiar surroundings with her family and did not require any emergency room visits or admission into the hospital during the last month of her life. She had excellent quality of life in the terminal period of her life, and could even participate in a family function during this time. The present case report suggests that acupuncture may have a role in treating neuropathic pain induced by bone metastasis in patients with advanced cancer across clinical and in-home settings.

The occurrence of hepatocellular carcinoma (HCC) is closely associated with viral hepatitis or alcoholic hepatitis. Although active surveillance is ongoing in Korea, advanced or metastatic HCC is found at initial presentation in many patients. Metastatic HCC presents with a hypervascular intrahepatic tumor and extrahepatic lesions such as lung or lymph node metastases. Cases of HCC presenting as carcinoma of unknown primary have been rarely reported. The authors experienced a case of metastatic HCC in a patient who presented with a metastatic bone lesion but no primary intrahepatic tumor. This case suggests that HCC should be considered as a differential diagnosis when evaluating the primary origin of metastatic carcinoma.

Invasion of the bile duct by hepatocellular carcinoma (HCC), which is called intrahepatic bile duct HCC, is rare and has a poor prognosis. Early diagnosis and surgical resection is important for treatment. A 58-year-old man who underwent hepatic resection for HCC 4 years ago and received transarterial chemoembolization (TACE) 2 years after the operation for recurred HCC presented with jaundice. CT scan revealed a tumor in the common bile duct without intrahepatic lesion. Therefore, ERCP was done to perform biopsy and biliary drainage. Histological examination was compatible with hepatocellular carcinoma. However, the tumor could not be visualized at angiography and thus, only transarterial chemoinfusion was performed without embolization. The tumor had disappeared on follow-up CT scan, and the patient has been disease free for 23 months without evidence of recurrence. Herein, we report a case of intrahepatic bile duct HCC which disappeared after ERCP.

Hepatoid adenocarcinoma (HAC) is a rare type of extrahepatic carcinoma whose morphology is similar to that of hepatocellular carcinoma (HCC). Metachronous HCC and HAC in the same patient is extremely rare. The case of a 68-year-old man with chronic hepatitis B infection who had both HCC and HAC of the stomach is reported herein. Nine years previously this patient had been diagnosed with HCC and received a right lobectomy. HCC that recurred at the caudate lobe at 6 months after the operation was successfully treated with transarterial chemoembolization. The patient was followed up regularly thereafter without evidence of tumor recurrence for 9 years. In July 2010 his serum alpha-fetoprotein (AFP) level elevated from 6.5 ng/mL to 625.4 ng/mL, and he developed a probable single metastatic lymph node around the hepatic artery without intrahepatic lesions. Subsequent evaluation with upper endoscopy revealed a 4-cm ulcerative lesion on the antrum of the stomach. Subtotal gastrectomy was performed with lymph-node dissection. Histologic examination revealed a special type of extrahepatic AFP-producing adenocarcinoma-HAC with lymph-node metastasis-which indicates that HAC can be a cause of elevated AFP even in patients with HCC. HAC should be considered if a patient with stable HCC exhibits unusual elevation of AFP.

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.

OBJECTIVETo investigate clinicopathological features of combined hepatocellular-cholangiocarcinoma (C-HCC-CC) with neuroendocrine carcinoma (NEC) differentiation and to review the literature.

METHODSThe clinical data, histological manifestations and immunohistochemical staining results of two cases of C-HCC-CC were analyzed along with a review of the current literature.

RESULTSBoth patients were male with an average age of 57.5 years. Both patients were positive for hepatitis B virus antigen. The tumors of both cases demonstrated the following 3 unequivocal mixed elements: (1) polygonal epithelial tumor cells growing in nests or trabeculae with positive staining for Hepatocyte and AFP, diagnostic of hepatocellular carcinoma (HCC). Cytoplasmic bile production was present in the tumor cells in one case; (2) elliptic or short spindle-shape small blue tumor cells growing in nests or organoid pattern with Syn/CgA/CD56 positivity confirming the presence of neuroendocrine carcinoma (NEC) component; (3) oval tumor cells growing in nests or glandular forms with positivity of CK19 and CK7 confirming differentiation of cholangiocarcinoma (CC). In both cases, the tumors contained at least 20% of each of HCC, NEC and CC components.

CONCLUSIONC-HCC-CC with NEC is a rare form of primary malignancy of the liver with a poor prognosis.

OBJECTIVETo investigate the effects of a Chinese herbal extract Songyou Yin on residual hepatocellular carcinoma after chemotherapy in nude mice and the relevant mechanisms.

METHODSOrthotopic nude mouse models bearing residual hepatocellular carcinoma after chemotherapy was established using human liver carcinoma MHCC97L cells. Three different doses of Songyon Yin (2.1 g/kg, 4.2 g/kg and 8.4 g/kg) were administered to the mice in the trial groups by intragastric gavage, respectively. The mice in the control group were administered physiological saline. The tumor growth, metastasis and survival in the mice of each group were recorded. The corresponding mechanisms were studied.

RESULTSThe pulmonary metastasis rates of the control group and 2.1g/kg, 4.2g/kg, 8.4g/kg Songyou Yin treatment group were 86.7%, 73.3%, 40.0%, and 20.0%, respectively, and the survivals of these groups were 53.83 ± 4.71, 56.50 ± 6.09, 66.67 ± 5.61, 81.17 ± 7.36 days, respectively. Compared with the mice in the control group, mice in the 4.2 g/kg, 8.4 g/kg Songyou Yin treatment groups had a lower pulmonary metastasis rate (P = 0.021 and P = 0.001, respectively) and longer survival (P = 0.002 and P = 0.001, respectively). A restoration of E-cadherin expression and a concomitant reduction of N-cadherin expression were detected in the tumors of the 4.2 g/kg and 8.4 g/kg Songyou Yin treatment groups.

CONCLUSIONSSongyou Yin effectively inhibits the invasion and metastasis of the residual hepatocellular carcinoma after chemotherapy in nude mice through attenuating the epithelia-mesenchymal transition and prolongs the survival. Songyon Yin may have potential to promote the efficacy of chemotherapy in hepatocellular carcinoma.

This manuscript describes an unusual case of rapid intra-hepatic dissemination of hepatocellular carcinoma with pulmonary metastases occurring 1 month after combined chemoembolization and radiofrequency ablation. Inferior vena cava and portal vein invasion tumor thrombus was also detected, possibly accounting for the mechanism of disease dissemination route of disease.

OBJECTIVETo explore the changes of metastatic potential of residual hepatocellular carcinoma (HCC) after in vivo chemotherapy and its mechanism.

METHODSNude mouse models of orthotopic HCC in the nude mouse livers was established using human hepatocellular carcinoma cell line MHCC97L cells. Oxaliplatin (10 mg/kg, once per week) was administered intraperitoneally (i.p.) to mice in the trial group. Mice in the control group received 0.2 ml of 0.9% sodium chloride on the same days. On day 7 after the third injection, all mice were sacrificed and tumor fragments of equal volume (2 mm×2 mm×2 mm) from each mouse of the oxaliplatin-treated and untreated groups were reinoculated into the livers of each new recipient mouse correspondingly. The growth, metastasis and molecular phenotype of the reinoculated tumors in both groups were determined.

RESULTSIn the new recipient mice, compared with untreated tumors, oxaliplatin pre-treated tumors grew significantly slower [(2624.59 ± 491.60) mm(3) vs. (3849.72 ± 827.09) mm(3), P < 0.001], but gave more spontaneous metastasis to the lung (10/12 vs. 3/12, P = 0.012). A decreased expression of E-cadherin and increased expression of N-cadherin, vimentin and transcription factor Snail were detected in the oxaliplatin pre-treated tumors by immunohistochemistry, which provided the evidence of epithelial mesenchymal transition (EMT) in these tumors.

CONCLUSIONResidual hepatocellular carcinomas after in vivo chemotherapy grow slower but gain enhanced metastatic potential to the lung, associated with epithelial mesenchymal transition.
