We have identified a novel human malignancy-associated gene (MAG) expressed in various malignant tumors including glioblastomas and hepatocellular carcinomas (HCCs) and in tumor preexisting conditions such as hepatitis C virus- and hepatitis B virus-induced liver cirrhosis. The expression of MAG was characterized using reverse transcription-PCR (RT-PCR), rapid amplification of cDNA ends PCR, RNA dot blotting, RNase protection assay, and Northern blot analysis. Rapid amplification of cDNA ends PCR yielded a 536-bp MAG fragment in HCC, macroregenerative liver nodules with dysplasia, and liver cirrhosis but not in normal liver or placenta. By RT-PCR, MAG expression was not found in 12 different normal tissues but found in 46 of 51 (90%) premalignant and malignant tissues of various sites. Embryonic liver and brain were positive for MAG expression together with tumors from the same organs, but the corresponding normal adult tissues were negative. By RNase protection assay, MAG mRNA was expressed in the HepG2 liver tumor cell line and in an ovarian carcinoma but not in normal liver. The estimated transcript size from Northern blot analysis was 8.8 kb. This novel gene may play a role in the progression of premalignant conditions and in the development of HCC and other cancers.

We describe two postmenopausal women with ascites and elevated CA-125 level, a serologic marker used to detect ovarian cancer. Both patients had unrecognized liver disease but underwent surgical exploration for suspected ovarian disease, which subsequently revealed benign pelvic organs. Elevated serum CA-125 levels have been reported in many patients with ascites due to liver disease and cirrhosis. Thus, the presence of both ascites and an elevated CA-125 level mandates a thorough elevation for liver disease as well as for a possibility of ovarian carcinoma. These cases outline the common finding and provide insight into the management of patients with ascites and elevated CA-125 values.

Cancer antigen 125 (CA-125) is usually used to monitor the course of epithelial ovarian cancer. It has recently been reported that liver cirrhosis is associated with elevated serum CA-125, especially in the presence of ascites. The aim of the study was to evaluate CA-125 as a marker of ascites in patients with liver cirrhosis. Seventy-two (72) patients with liver cirrhosis of different aetiology were studied. Ca-125 levels were measured in stored serum collected from the patients. Ca-125 concentrations were elevated in patients with liver cirrhosis and ascites, irrespective of patients' sex and cirrhosis aetiology. CA-125 concentrations were normal in cases of liver cirrhosis without ascites. Elevated cancer antigen 125 is a sensitive marker of cirrhotic ascites. An inappropriate use of this test in cases of liver cirrhosis in females may suggest the ovarian cancer incident and lead to unnecessary surgical intervention.

Matrix metalloproteinases (MMPs) are proteolytic enzymes that are implicated in multiple stages of cancer progression including invasion and metastasis. MMPs exert these effects by cleaving a diverse group of substrates, which include not only structural components of the extracellular matrix, but also growth factor receptors. By gelatin zymography we verified MMP activity in the pleural effusions of patients with benign and malignant disease. Of these patients, 32 had malignant pleural effusion, consisting of 20 breast cancer, 6 non-small cell lung carcinoma, 4 ovarian carcinoma, and 2 colonic adenocarcinoma, and 10 had benign pleural effusion (5 pleurisy and 5 cirrhosis). Zymography showed the constant presence of a substantial amount of MMP-2 in all samples analyzed, whereas MMP-9 was present to lesser quantities. MMP-2 activity was enhanced in pleural effusions from patients with benign diseases compared with cancer patients. MMP-9 was present in 59% of cancer patients and the lytic activity was enhanced in pleurisy and absent in cirrhosis. Furthermore, we determined the pleural effusion levels of the soluble extracellular domain of HER-2/neu. The levels of HER-2/neu ECD were above the cut-off value in breast cancer patients. No correlation between gelatinolytic activities and high HER-2/neu ECD values was found.

From March 1991 through 31st December 2007, 2042 patients underwent stem cell transplantation at the Hematology-Oncology and Stem Cell Transplantation Research Center, affiliated to Tehran University of Medical Sciences. These transplantations included 1405 allogeneic stem cell transplantation, 624 autologous stem cell transplantation, and 13 syngeneic stem cell transplantation. Stem cell transplantation was performed for various diseases including acute myelogenous leukemia, acute lymphoblastic leukemia, chronic myelogenous leukemia, chronic lymphoblastic leukemia, thalassemia major, sickle cell thalassemia, sickle cell disease, multiple myeloma, myelodysplasia, mucopolysaccharidosis, paroxysmal nocturnal hemoglobinuria, non-Hodgkin's lymphoma, Hodgkin's disease, severe aplastic anemia, plasma cell leukemia, Niemann-Pick disease, Fanconi anemia, severe combine immunodeficiency, congenital neutropenia, leukocyte adhesion deficiencies, Chediak-Higashi syndrome, osteopetrosis, histiocytosis X, Hurler syndrome, amyloidosis, systemic sclerosis, breast cancer, Ewing's sarcoma, testicular cancer, germ cell tumors, neuroblastoma, medulloblastoma, renal cell carcinoma, nasopharyngeal carcinoma, ovarian cancer, Wilms' tumor, rhabdomyosarcoma, pancreatoblastoma, and multiple sclerosis. We had 105 cellular therapies for postmyocardial infarction, multiple sclerosis, cirrhosis, head of femur necrosis, and renal cell carcinoma. About 30 patients were retransplanted in this center. About 74.9% of the patients (1530 of 2042) remained alive between one to 168 months after stem cell transplantation. Nearly 25.1% (512 of 2042) of our patients died after stem cell transplantation. The causes of deaths were relapse, infections, hemorrhagic cystitis, graft versus host disease, and others.
