Viable and stable human cancer cell lines and animal models combined with adequate clinical information are essential for future advances in cancer research and patient care. Conventional in vitro cancer cell lines are commonly available; however, they lack detailed information on the patient from which they originate, including disease phenotype and drug sensitivity. Patient-derived xenografts (PDX) with clinical information (so-called 'cancer xenopatients') are a promising advance that may accelerate the development of anticancer therapies...

Persistent viruses are kept in check by specific lymphocytes. The clonal T cell receptor (TCR) repertoire against Epstein-Barr virus (EBV), once established following primary infection, exhibits a robust stability over time. However, the determinants contributing to this long-term persistence are still poorly characterized. Taking advantage of an in vivo clinical setting where lymphocyte homeostasis was transiently perturbed, we studied EBV antigen-specific CD8 T cells before and after non-myeloablative lympho-depleting chemotherapy of melanoma patients...

BACKGROUND: Ulcerative colitis (UC) and Crohn's disease can sometimes relapse and be refractory to standard treatment following orthotopic liver transplantation (OLT) despite post-transplantation immunosuppressive therapy. AIM: To evaluate the efficacy and safety of anti-tumour necrosis factor (anti-TNF) agents for the management of IBD following OLT. METHODS: We reviewed the records of patients with a diagnosis of IBD who underwent OLT at Mayo Clinic Rochester between 1985 and 2009...

Lymphoepithelioma-like carcinoma (LELC) of the uterine cervix is a rare variant of squamous cell carcinoma of the uterine cervix. This tumor is characterized by nests of poorly differentiated epithelial cells surrounded by a prominent lymphocytic infiltration. Despite the poorly differentiated pathological findings, it appears to have a better outcome than the usual squamous cell carcinoma of the uterine cervix. Therefore, it is quite important to differentiate this tumor from poorly differentiated squamous cell carcinoma and lympho-proliferative disorders of the cervix...

Post-transplantation lymphoproliferative disorder (PTLD) with plasmacellular differentiation has been reported as a rare subtype of monomorphic B-cell post-transplant lympho-proliferation with histological and immunophenotypical features of plasmacytoma in the non-transplant population. Here we present clinical, laboratory and histopathological features, treatment and outcome of 8 patients from the German prospective PTLD registry. Clinically, extranodal manifestations were common while osteolytic lesions were rare and none of the patients had bone marrow involvement...

Natural killer (NK) cell neoplasms, which include extra-nodal NK/T-cell lymphoma (nasal and extra-nasal) and aggressive NK cell leukaemia, are generally rare, but they are more common in people of Oriental, Mexican and South American descent. These neoplasms are highly aggressive, and show a strong association with Epstein-Barr virus. Aggressive NK cell leukaemia affects younger patients, who present with poor general condition, fever, and disseminated disease; they often die within a short time from systemic disease or complications such as multi-organ failure...

BACKGROUND: Hodgkin lymphoma, Non-Hodgkin lymphoma, multiple myeloma, and acute and other leukaemias constitute about 7% of the overall cancer incidence and 8% of cancer mortality in the Nordic countries. The aim of this study is to describe and interpret the trends in relative survival and excess mortality in the five Nordic populations among these patients. MATERIAL AND METHODS: Using the NORDCAN database 1964-2003, we estimated age-standardised incidence and mortality rates, 5-year relative survival, and excess mortality rates for varying follow-up periods, and age-specific 5-year relative survival by country, sex, and 5-year diagnostic period...

X-linked lympho-proliferative (XLP) is an immunodeficiency condition caused by mutation or deletion of the gene encoding the adaptor protein SAP/SH2D1A. Besides defects in T cell and NK cell function and an absence of NKT cells, XLP can also manifest as lymphomas resulting primarily from uncontrolled B cell proliferation upon acute infection by Epstein-Barr virus. While it has been demonstrated that SAP regulates the functions of T cells and NK cells through the SLAM family of immunoreceptors, its role in B cells has not been defined...

Hemophagocytic lymphohistiocytosis is a rare and potentially fatal syndrome associated with a variety of genetic, malignant, autoimmune, or infectious conditions. The importance of cutaneous presentations of this syndrome has only recently been brought forward. We report the first case of Epstein-Barr-virus-associated hemophagocytic lymphohistiocytosis presenting with papulonodular and granulomatous skin lesions. A girl of African origin developed several umbilicated papules on her extremities and face at the age of 18 months...

BACKGROUND: Chronic enterocolitis is rare in infancy and accounts for less than 0.5% of all newly diagnosed inflammatory bowel disease (IBD) in the UK. Presentation at this young age is usually indicative of underlying immunodeficiency/immunodysregulation. A group of such infants suffer intractable ulcerating enterocolitis of infancy (IE) in which there is a pan-enteritis with marked oro-anal involvement and deep flask like mucosal ulcers throughout the colon. METHODS: Retrospective review of presenting features, treatment and long-term outcome in a series of 8 children with typical IE...

More than half of patients with X-linked lympho-proliferative disease, which is caused by a defect in the intracellular adapter protein SH2D1A, suffer from an extreme susceptibility to Epstein-Barr virus. One-third of these patients, however, develop dysgammaglobulenemia without an episode of severe mononucleosis. Here we show that in SH2D1A(-/-) mice, both primary and secondary responses of all Ig subclasses are severely impaired in response to specific antigens. Because germinal centers were absent in SH2D1A(-/-) mice upon primary immunization, and because SH2D1A was detectable in wt germinal center B cells, we examined whether SH2D1A(-/-) B cell functions were impaired...

Recipients of renal transplants have an increased risk of developing secondary malignancies. About 4% of patients who underwent kidney transplantation will develop cancer, and 1% of transplanted patients will develop lymphoproliferative disorders. According to clinical analyses and laboratory data, the main reason for increased risk of developing malignant disease in this group of patients, is their immunocompromised status due to immunosuppressive treatment. So called "strong" immunosuppressive drugs like antilymphocytic globulin (ALG), antithymocytic globulin (ATG), or monoclonal globulin OKT3 seem to favor the development of secondary malignancies much more than other drugs, like: corticosteroids, azathioprine (AZA), or cyclosporine (CsA)...

The activation antigen CD30 (Ki-1) which is expressed by the lymphocytes T and B is related to the "nerve growth factor" (NFGR) like the receptor of the "tumor necrosis factor" (TNF) and is expressed in the group of large-cell anaplastic lymphoma (ACLC) and Hodgkin's lymphoma and in non-Hodgkin's lymphoma and within the T cells of infectious Mononucleosis. We describe a case of a 18 year-old who contracted Acute Infectious Mononucleosis showing lateral cervical lympho adenopathy. The histologic examination was suggestive for a large-cell anaplastic lymphoma with the antigen CD30, expressed by severa atypical immunoblasts...

The relative contribution of tumour histology or molecular changes, compared with invasion pattern or stage, to prognostic assessment of gastric cancer was investigated in a series of 185 advanced (T2 to T4, stage IB to IV) cancers that had undergone intentionally curative surgery at Varese General Hospital. Survival analysis of the histological types considered in commonly used classifications, such as Lauren, Kubo, the World Health Organization (WHO) and related classifications, allowed separation of a small high-grade (Hg, 12 cases) group of adenosquamous, anaplastic and small cell endocrine carcinomas from a large cohesive group (C, 86 glandular or solid cancers) and from another large (87 cases) group of tumours with dissociated cells [29 diffuse (D) and 58 mixed (M) tumours]...

Delivering a gene into the Epstein-Barr virus (EBV)-transformed B cells is useful in studying effects of the gene on B-cell functions. However, although people have been able to efficiently transfer genes into and get them expressed in B-lympho blastoid cells for a time probably long enough to kill the cells using vectors harbouring oriP, the expression time of the delivered gene is not long enough in order to study the gene function in B cells. To solve this problem, we constructed an adeno-associated virus (AAV) plasmid pAGX(+) based on plasmids pSub201 and pRc/CMV...

OBJECTIVE: A variety of carcinomas (CA) can metastasize to the lymph nodes of the neck. Differentiation of CA in the lymph nodes according to their resemblance to the structure of origin is the basis of histopathological diagnosis. However, during the course of the disease, e.g. tumor recurrence after ablative surgery, these tissues can completely lose the ability to imitate typical structures of the organ that gave rise to malignant transformation. This can result in the inability of the pathologist to identify the origin of the metastases...

Our purpose was to establish a reproducible xenogeneic chimera model to observe tumors similar to the well-known human posttransplant lymphoproliferative disease (LPD). First we followed the original protocol injecting Epstein-Barr virus positive (EBV+) human peripheral blood lymphocytes (PBL) intraperitoneally into immunodeficient (SCID) mice. Human cells showed T cell phenotype in majority one week after the transfer, whereas one month later a shift towards B cell phenotype was evident according to immunohistochemical and flow cytometric analysis...

BACKGROUND: Several studies have established that Epstein-Barr virus (EBV) is associated with lympho-proliferative disorders such as Burkitt's lymphoma and Hodgkin's disease. EBV is also present in undifferentiated nasopharyngeal carcinomas and in tumors of similar morphology (lymphoepithelioma-like carcinomas) arising in a variety of organs, predominantly in stomach, salivary gland and thymus. As reports of EBV-positive thymic epithelial tumors (TET) have been divergent and as different methods have been used to detect EBV, the aim of this study was to investigate the possible role of EBV in TET of Danish patients...
