A 74-year-old woman was admitted to our hospital to treat her hepatocellular carcinoma (stage IVB) with multiple lung metastases. She was treated with 3 times of hepatic arterial infusion of cisplatin powder (IA-call). After the treatment, liver mass and lung tumors were disappeared and high levels of tumor markers (AFP and PIVKA-II) were markedly decreased. These data revealed that a complete response (CR) was obtained for her. She has still been maintained in CR for 2 years since the first treatment.

A 61-year-old male was admitted for advanced hepatocellular carcinoma (HCC) with multiple lung metastases and tumor thrombus in the portal vein and superior vena cava. At first, we planned to perform transcatheter arterial embolization (TAE) to avoid the rupture of the liver tumor. But, due to the severe liver dysfunction, ie Child-Pugh C and 36% ICG R15, hepatic arterial infusion (HAI) of epirubicin 40 mg was performed. After that, the patient was followed at the outpatient ward and his general condition has gradually improved without a special treatment. At the present, one year and ten month after HAI, the serum alpha-fetoprotein (AFP) is almost within normal limits and CT scans show that HCC with multiple lung metastases, and tumor thrombus in the portal vein and superior vena cava almost disappeared. Although, spontaneous regression of HCC was a rare phenomenon, it might have played a major role in the good anticancer efficacy of this patient as well as high anti-cancer agent sensitivity of his liver tumor.

We report the case of a patient having hepatocellular carcinoma with tumor invasion to the inferior vena cava and with multiple pulmonary metastases who was treated with repeated one-shot administration of epirubicin, cisplatin, and mitomycin C by hepatic artery and bronchial artery, which led to complete remission. A 72-year-old woman was diagnosed with infiltrative hepatocellular carcinoma with Vv3, multiple intrahepatic metastases, and multiple pulmonary metastases associated with compensated liver cirrhosis. One-shot infusion of epirubicin, cisplatin, and mitomycin C was performed through proper hepatic artery and bronchial artery for twice at eight weeks of intervals. Pulmonary metastases disappeared and intrahepatic lesions indicated marked shrinkage leaving a scar-like lesion with decreases in tumor markers. After six months and 20 months, tumor markers indicated increasing tendency but no evident recurrence was found by computed tomography or hepatic arteriography. One-shot infusion of the same regimens through proper hepatic artery was performed and tumor markers decreased to normal levels. After 14 months of the last therapy, no evidence of recurrence has been found on image analysis or in tumor markers. This arterial infusion therapy is well tolerated for the patients with compensated liver cirrhosis and might be promising for the effective treatment of advanced hepatocellular carcinoma with pulmonary metastases.

Oncolytic viruses represent novel tools for cancer treatment. Besides specifically killing cancer cells (oncolysis), these agents also provide danger signals, prompting the immune system to eliminate virus-infected tumours. As a consequence of oncolytic events, the innate and adaptive immune systems gain access to tumour antigens, which result in cross-priming and vaccination effects. Here the aim was to see whether we could enhance this adjuvant capacity by incorporating immunostimulatory CpG motifs into the single-stranded genome of an oncolytic parvovirus (H-1PV). We engineered 2 CpG-enriched H-1PV variants (JabCG1 and JabCG2), preserving both the replication competence and the oncolytic features of the parental virus. In keeping with their increased CpG content, the JabCG1 and JabCG2 genomes proved in vitro to be more potent triggers of TLR-9-mediated signalling than wild-type H-1PV DNA. Antitumour activity was evaluated in a rat model of MH3924A hepatoma lung metastases, where an infection with parental or modified viruses served as an ex vivo adjuvant to a subcutaneously administered autologous cell vaccine. In this setup, which excludes direct oncolytic effects on metastases, the JabCG2 vector displayed enhanced immunogenicity, inducing markers of cellular immunity (IFN gamma) and dendritic cell activation (CD80, CD86) in mediastinal (tumour-draining) lymph nodes. This led to a significantly reduced metastatic rate (50%) as compared to other vaccination schedules (H-1PV-, JabCG1-, JabGC- or mock-treated cells). The data provide proof of principle that increasing the number of immunostimulatory CpG motifs within oncolytic viruses makes it possible to improve their overall anticancer effect by inducing antitumour vaccination.

In human hepatocellular carcinoma (HCC), epithelial to mesenchymal transition (EMT) correlates with aggressiveness of tumors and poor survival. We employed a model of EMT based on immortalized p19(ARF) null hepatocytes (MIM), which display tumor growth upon expression of oncogenic Ras and undergo EMT through the synergism of Ras and transforming growth factor (TGF)-beta. Here, we show that the interleukin-related protein interleukin-like EMT inducer (ILEI), a novel EMT-, tumor- and metastasis-inducing protein, cooperates with oncogenic Ras to cause TGF-beta-independent EMT. Ras-transformed MIM hepatocytes overexpressing ILEI showed cytoplasmic E-cadherin, loss of ZO-1 and induction of alpha-smooth muscle actin as well as platelet-derived growth factor (PDGF)/PDGF-R isoforms. As shown by dominant-negative PDGF-R expression in these cells, ILEI-induced PDGF signaling was required for enhanced cell migration, nuclear accumulation of beta-catenin, nuclear pY-Stat3 and accelerated growth of lung metastases. In MIM hepatocytes expressing the Ras mutant V12-C40, ILEI collaborated with PI3K signaling resulting in tumor formation without EMT. Clinically, human HCC samples showed granular or cytoplasmic localization of ILEI correlating with well and poorly differentiated tumors, respectively. In conclusion, these data indicate that ILEI requires cooperation with oncogenic Ras to govern hepatocellular EMT through mechanisms involving PDGF-R/beta-catenin and PDGF-R/Stat3 signaling.

We report the successful treatment of multiple lung metastases after hepatic resection for hepatocellular carcinoma (HCC) with combined docetaxel, cisplatin (CDDP), and enteric-coated tegafur/uracil (UFT-E). A 68-year-old man was diagnosed with multiple lung metastases of HCC 7 mo after partial hepatectomy for HCC. Oral UFT-E was given daily and docetaxel and CDDP were given intra-arterially (administered just before the bronchial arteries) every 2 wk via a subcutaneous injection port. One month after starting chemotherapy, levels of tumor marker, protein induced by vitamin K absence II (PIVKA-II), decreased rapidly, and after a further month, chest X-ray and computed tomography revealed the complete disappearance of multiple liver metastases. Two years after the combined chemotherapy, HCC recurred in the liver and was treated but no pulmonary recurrence occurred. In the absence of a standardized highly effective therapy, this combined chemotherapy with docetaxel, CDDP and UFT-E may be an attractive option for multiple lung metastases of HCC.

A 75-year-old man received lung radiofrequency (RF) ablation to treat lung metastases from hepatocellular carcinoma. Massive hemoptysis occurred 1 week after lung RF ablation. Emergent contrast-enhanced CT and pulmonary arteriography revealed a pulmonary artery pseudoaneurysm, which was embolized with coils. The postembolization course was uneventful. Hemoptysis did not recur for 5 months.

Patients with chronic liver disease exhibit various cardiovascular and pulmonary complications. Hepatopulmonary syndrome results in dyspnea due to intrapulmonary arteriovenous shunting and ventilation-perfusion mismatch. Portopulmonary hypertension occurs in patients with portal hypertension. Intrathoracic portosystemic collateral vascular pathways develop in patients with portal hypertension to allow decompression of the portal vein into the systemic circulation. Hepatic hydrothorax may develop in patients with cirrhosis and ascites. Massive necrosis of the liver from any cause may be associated with acute hypoxic respiratory failure, necessitating ventilatory support. Bacterial infection is common in cirrhotic patients because of a compromised host defense system. Hepatocellular carcinoma may produce hematogenous lung metastases, intrathoracic lymph node metastases, direct intracardiac extension, and pulmonary embolism. Interferon therapy for treatment of chronic active hepatitis C may disturb cellular immune activation in some patients and contribute to the onset and progression of sarcoidosis. Awareness of the various thoracic manifestations in chronic liver disease can be helpful for making a differential diagnosis and planning proper management.

A 73-year-old woman was admitted to our hospital for hemorrhagic shock due to HCC rupture and treated by transcatheter arterial chemoembolization (TACE) in July 2007, followed by partial hepatic resection two months later. Multiple pulmonary and remnant liver metastases were detected by CT six months after the surgery. Since treatment with UFT for two months was not effective, the chemotherapy was changed to S-1 100 mg/body/day in June 2008. After S-1 treatment for three months, lung metastases remarkably diminished, as did the serum AFP level. Meanwhile, although the S-1 dose was gradually reduced to 50 mg/body/day due to adverse effects, pulmonary lesions and serum AFP level remained stationary for five months. While there is no established regimen for distant metastases of HCC, S-1 may be effective even at a reduced dose.

Pulmonary metastasis is the most significant prognostic determinant for osteosarcoma, but methods for its prediction and treatment have not been established. Using oligonucleotide microarrays, we compared the global gene expression of biopsy samples between seven osteosarcoma patients who developed pulmonary metastasis within 4 years after neoadjuvant chemotherapy and curative resection, and 12 patients who did not relapse. We identified argininosuccinate synthetase (ASS) as a gene differentially expressed with the highest statistical significance (Welch's t test, P = 2.2 x 10(-5)). Immunohistochemical analysis of an independent cohort of 62 osteosarcoma cases confirmed that reduced expression of ASS protein was significantly correlated with the development of pulmonary metastasis after surgery (log-rank test, P < 0.05). Cox regression analysis revealed that ASS was the sole significant predictive factor (P = 0.039; hazard ratio, 0.319; 95% confidence interval, 0.108-0.945). ASS is one of the enzymes required for the production of a nonessential amino acid, arginine. We showed that osteosarcoma cells lacking ASS expression were auxotrophic for arginine and underwent G(0)-G(1) arrest in arginine-free medium, suggesting that an arginine deprivation therapy could be effective in patients with osteosarcoma. Recently, phase I and II clinical trials in patients with melanoma and hepatocellular carcinoma have shown the safety and efficacy of plasma arginine depletion by stabilized arginine deiminase. Our data indicate that in patients with osteosarcoma, reduced expression of ASS is not only a novel predictive biomarker for the development of metastasis, but also a potential target for pharmacologic intervention.
