In January 1990 a 32 year old nurse was admitted with fever, weight loss of 9 kilogramms and pain of her right flank. HIV infection due to intravenous drug abuse had been diagnosed in 1986. Ultrasonic imaging revealed a solid tumor of low echogenicity in the cranial part of the right kidney. This finding could be confirmed with computed tomography and magnetic resonance imaging. Angiographic study showed a missing of blood vessels in the same area. A transcutaneous puncture with a thin needle resulted histologically in unspecific findings like detritus, lymphoid cells and neutrophils. Antibiotic treatment with amoxicilline and cefuroxim was without success. Symptoms as well as ultrasonic findings completely disappeared following oral administration of ofloxazine. The clinical course and the successful treatment support the diagnosis of an atypical renal abscess. As a second diagnosis a histologically proven cirrhosis of the liver could be established. Hepatitis C serology proved to be positive.

A case-control study of risk for hepatocellular carcinoma (HCC) was carried out in our Department from December 1980 to December 1983. One hundred and twenty consecutive inpatients with HCC were compared with 360 controls pair-matched by sex and age (within years). For each case three different controls were selected from inpatients at the same hospital: one patient with liver cirrhosis; one patient with solid tumor and one patient with chronic illness other than neoplasm or liver disease. We report here the results on alcohol consumption, smoking habit and hepatitis B virus infection. The risk factors investigated are distributed similarly in HCC and cirrhosis. The prevalence of alcohol abuse in HCC is similar to that in cirrhosis and is significantly higher than in other neoplastic or otherwise chronically ill patients (odds ratio 2 X 3 and 3 X 2 respectively). Thus alcohol abuse is probably a risk factor for HCC as a cause of cirrhosis. Smoking habits were similar among the various disease groups and independent of alcohol consumption. The prevalence of heavy smoking was comparable in cases and controls. HbsAg negative-HCC with an ultrasonographic pattern of 'diffuse' alteration was more frequent in heavy smokers.

Positron emission tomography (PET) is a noninvasive functional method for the study of solid tumor perfusion, metabolism and interaction with different therapeutic agents. The aim of the study was the investigation of the metabolism of hepatocellular carcinomas (HCC) and the kinetics during a treatment with intratumoral ethanol by PET. The ongoing study includes seven patients with child. A cirrhosis and HCC (UICC stage III-IVA; tumor size 3-6 cm). Dynamic PET studies (60 min) with 18F-fluordeoxyglucose (FDG) were performed prior to therapy to assess tumor viability. The evaluation of the FDG data demonstrated a liver-equivalent uptake in six of the tumors (well and moderately differentiated HCC), which were poorly delineated against the normal liver parenchyma. One moderately differentiated HCC showed an increased FDG metabolism, indicating no correlation between histology and metabolism. A dose of 37-80 MBq 11C-ethanol was applied together with a nonlabelled therapeutic dose of the drug via a puncture needle positioned under sonography. Five out of seven tumors demonstrated a high 11C uptake shortly after the end of the ethanol injection followed by constant 11C-ethanol concentration during the whole study period of 45 min. The PET data demonstrated no significant elimination of the 11C-ethanol from the tumor and no accumulation in the surrounding liver tissue. One case showed a decrease of the intra-tumoral 11C-ethanol concentration due to a punkture of a tumor vein, and in another case the surrounding liver parenchyma demonstrated significant 11C uptake in the early phase following paratumoral injection of the drug. In conclusion, PET is a useful tool for the study of the mechanism and the kinetics of percutaneous intratumoral ethanol injection of HCC.

We report here the case of a 17-year-old female with typical fibrolamellar hepatocellular carcinoma, no hepatitis B or C viral infection and a normal, non-cirrhotic liver. Computed tomography and magnetic resonance imaging revealed a solid tumor with a central fibrous scar. A fibrolamellar hepatocellular carcinoma is an uncommon malignancy of unknown etiology, without cirrhosis, usually without an increase in tumor markers, and rarely associated with hepatitis B virus. It occurs mainly in young patients. This tumor presents a high resectability rate (48-100%), a good prognosis and a mean survival of 68 months. This tumor is an important differential diagnosis of space occupying lesions in younger adults.

Hepatocellular cancer (HCC) is the fifth most common solid tumor worldwide, accounting for 500,000 new cases annually. Although less common in the United States, HCC is expected to increase in incidence over the next two decades largely because of the prevalence of hepatitis C virus infection. A majority of patients present with advanced disease and are not candidates for liver transplantation, surgical resection, or regional therapy. In 60% to 80% of patients with HCC, treatment is complicated by underlying liver cirrhosis and hepatic dysfunction. Systemic treatments are minimally effective, can have significant toxicity, and have not been shown to improve patient survival. New approaches targeting molecular abnormalities specific to HCC are needed to improve patient outcome. This review summarizes the state of knowledge of those key aspects of the molecular pathogenesis of HCC that may represent rational therapeutic targets in this disease. Relevant preclinical and clinical information on novel compounds directed toward abnormalities in HCC is reviewed.

This study evaluated the significance of circulating bone marrow-derived endothelial progenitor cells (EPCs) in patients with hepatocellular carcinoma (HCC), a solid tumor with rich neovasculature. Eighty patients with HCC were recruited for the study, and 16 patients with liver cirrhosis and 14 healthy subjects were also included for comparison. Blood samples were taken before treatment. Total mononuclear cells were isolated from peripheral blood, preplated to eliminate mature circulating endothelial cells, and colony-forming units (CFUs) formed by circulating EPCs were counted. To validate the CFU scores, FACS quantification of EPCs using CD133, VEGFR2, and CD34 as markers was performed in 30 cases. Our study showed significantly higher mean CFU scores in patients with HCC compared to patients with cirrhosis and healthy controls (P = .001 and .009, respectively). Furthermore, the CFU scores of patients with HCC positively correlated with levels of serum alpha-fetoprotein (r = .303, P = .017), plasma VEGF (r = .242, P = .035), and plasma interleukin-8 (IL-8) (r = .258, P = .025). Patients with unresectable HCC had higher CFU scores than patients with resectable tumors (P = .027). Furthermore, for those who underwent curative surgery, higher preoperative CFU scores were observed in patients with recurrence within 1 year compared with those who were disease-free after 1 year (P = .013). In conclusion, higher circulating levels of EPCs are seen in patients with advanced unresectable HCC as compared to patients with resectable HCC or those with liver cirrhosis. Our evidence supports the potential use of circulating level of EPCs as a prognostic marker in patients with HCC.

Ever since the first embryonic stem cells were isolated in the 1990s scientists and clinicians as well as the general public have followed the development of the field with great attention. As unspecialized cells capable of dividing, renewing and differentiating into specialized cells, stem cells hold great promise as a therapeutic strategy for many diseases, especially those of degenerative nature. In 2006, stem cells were actively investigated in preclinical and clinical settings to manage heart failure, amyotrophic lateral sclerosis, spinal cord injury, stroke, hematologic disorders, renal cell carcinoma, solid tumor cancer, Crohn's disease and cirrhosis, among other disorders. Likewise, biotech and pharmaceutical industry highlighted stem cells and associated products and technologies as useful tools for drug discovery that provide relevant clinical models and ensure efficacious transition of investigational compounds into preclinical testing.

Primary effusion lymphoma (PEL) is an unusual form of non-Hodgkin's lymphoma, which is characterized by lymphomatous effusion in body cavities, but no associated mass lesions. It is usually associated with an immunodeficient state most often with the human immunodeficiency virus (HIV). We describe a 54-year-old man with HIV-negative PEL, with a history of hepatitis B virus-related liver cirrhosis. Both abdominal and pleural cavities were involved; no solid tumor masses were found and bone marrow investigations were normal. The ascites and pleural effusion contained numerous pleomorphic lymphoid cells. Immunophenotyping was positive for CD138. Chromosome study showed complex cytogenetics. The genomic human herpesvirus-8 was detected in the lymphoma cells. It is postulated that the immunosuppressed state in this patient may have been caused by cirrhosis. The patient received four cycles of chemotherapy of CHOP and Picibanil (OK-432) intraperitoneal administration. However, no durable remission was achieved. Adefovir failed to halt the progressive liver failure after the development of YMDD mutant related to lamivudine. He died of sepsis and hepatic failure.

A 67-year-old man had pain and swelling in the bilateral inguinal region. His past medical history included non-alcoholic steatohepatitis and liver cirrhosis. A clinical examination revealed a solid mass that was palpable along with the bilateral spermatic cord from the external inguinal ring to the root of the scrotum. Other than a hydrocele in the right testis, the epididymis and testes were intact. Abdominal computed tomography showed ascites and a solid tumor of the bilateral spermatic cord. Magnetic resonance imaging findings did not suggest malignancy, while antibiotics showed no effects. The patient wanted relief from the inguinal pain and a bilateral high orchiectomy was performed, during which time the spermatic cord was found firmly adhered to the surrounding tissue, and could not be completely resected. A histopathological examination showed epithelial mesothelioma. For additional examination of the ascites, the patient underwent paracentesis, which revealed an extremely high level of hyaluronic acid. Our working diagnosis was peritoneal malignant mesothelioma that had infiltrated the bilateral spermatic cord. We began systemic chemotherapy treatment with pemetrexed and cisplatin, but, the patient died 3 months after the operation.
