Systemic sclerosis (SSc) is an autoimmune connective tissue disease with multisystem involvement. An increased incidence of cancer in SSc patients compared with the general population has been reported in several reports. Our aims in this study were to determine the most common malignancies and to investigate the possible risk factors for the development of malignancy in patients with SSc. Three hundred forty SSc patients from 13 centers were included to the study. Data of the patients were obtained by evaluating their medical records retrospectively...

OBJECTIVE: To study the role of arginase-1 (Arg-1) expression in differential diagnosis of hepatocellular carcinoma (HCC), Arg-1 staining pattern in clear cell neoplasm (HCC and non-HCC) and Arg-1 expression in non-hepatocellular tumors. METHODS: Seventy-eight cases of HCC (including 8 cases of clear cell type and 70 cases of non- clear cell type) and 246 cases of non-hepatocellular neoplasms (including 29 cases of metastatic tumors such as breast cancer, nasopharyngeal carcinoma and neuroendocrine carcinoma, 77 cases of tumors with clear cell changes such as malignant melanoma, clear cell renal cell carcinoma and alveolar soft part sarcoma, and 140 cases of other types of tumors such as ovarian endometrioid adenocarcinoma, pituitary tumor and thyroid papillary carcinoma) were studied...

PAX8 is expressed in a high percentage of renal cell and ovarian cancers; however, the current existing anti-PAX8 rabbit polyclonal (P) antibodies also recognize B cells, pancreatic cancers, carcinoids, and some soft tissue tumors. Cross-reactivity with B cells can be especially troublesome in lymph nodes when identifying tumors of unknown origin. A new mouse monoclonal (M) anti-PAX8 antibody (Clone BC12) has been developed that recognizes PAX8 expression in a high percentage of renal cell and ovarian carcinomas, whereas exhibiting no staining of B cells...

Alpha-methylacyl CoA racemase (AMACR), also known as P504S, plays an important role in peroxisomal beta-oxidation of branched-chain fatty acids. It has recently been shown that AMACR is highly expressed in prostate cancer and that it may be an important diagnostic marker for prostate carcinoma. However, little is known about expression of AMACR in normal tissues and other malignant tumors. In this study, we investigated expression of AMACR in 539 malignant tumors and 222 normal human tissues of various types by immunohistochemical analysis...

The transgene expression of the catalytic subunit APOBEC-1 of the apo B mRNA editing enzyme-complex can cause hepatocellular carcinoma in mice and rabbits. It has been proposed that aberrant editing of mRNA may represent a novel oncogenic principle. This investigation aimed to define whether such aberrant hyperediting mediated by APOBEC-1 occurs in human carcinomas. Editing and hyperediting of apo B, NAT1 or NF1 mRNA was not identified in any of 28 resected tumor specimens, including hepatocellular, bile duct, gastric, colorectal, pancreatic adeno- and neuroendocrine, lung adeno-, medullary thyroid and breast carcinoma, soft tissue sarcoma and neuroblastoma...

BACKGROUND: The vascular system of the tumor bed plays an important function in tumor growth regulation. Recent studies have suggested that the vasoactive peptides somatostatin and substance P may have a potential role in the tumor bed of selected tumors. METHODS: In the current study, somatostatin receptors were evaluated with in vitro receptor autoradiography using 125I-[Tyr3]-octreotide in the peritumoral vessels of a large group of 215 primary human tumors and 25 metastases of various tumor origin, with particular emphasis on receptor incidence, distribution, homogeneity, and density...

We studied by immunocytochemistry 573 tissue and 106 cytologic samples of human tumors, non-neoplastic proliferative lesions and normal tissues with the monoclonal antibody (Mab) A-80 that recognizes a mucinous glycoprotein from the colon carcinoma cell line LS-174T. The spectrum of benign and malignant breast lesions was studied as were epithelial tumors of the colon, stomach, pancreas, lung, salivary glands, thyroid, prostate, kidney, endometrium, skin and mesothelium; non-epithelial tumors included lymphomas, melanomas, gliomas, meningiomas, and sarcomas of soft tissue and bone...
