INTRODUCTION: Secondary pancreatic tumors are uncommon and account for 2-5% of pancreatic cancer. Tumors characterized most commonly with pancreatic involvement are lymphoma, renal cell and lung carcinomas. PRESENTATION OF CASE: A 76-year-old female patient with obstructive jaundice as the primary symptom and inguinal lymphadenopathy is presented. Imaging revealed a bulky solitary solid pancreatic head mass along with paraaortic and mesenteric lymphadenopathy. The absence of a previous history of malignancy and the presence of a dominant pancreatic mass along with distal lymphadenopathy confined differential diagnosis to advanced secondary pancreatic lymphoma, which is the most common secondary pancreatic tumor, and locally advanced/metastatic pancreatic adenocarcinoma...

Primary bone lymphoma is a rare disease, accounting for less than 5% of all extranodal lymphoma. Although the femur is cited as being the most common site, primary bone lymphoma is rare, accounting for less than 1% of all non-Hodgkin's lymphoma. Herein we present a case of diffuse B-cell-type malignant lymphoma manifested as a large soft-tissue mass of the leg, via metastasis of primary non-Hodgkin's lymphoma of the femur, which went untreated. We highlight the advantages of various imaging modalities used throughout the process of diagnosis and treatment because accurate and early diagnosis are essential...

IgG4-related disease is a heterogeneous immune-mediated fibroinflammatory condition that can affect every single organ. This disease is more prevalent in the elderly (the mean age of patients is above 60 years) and the prevalence rate is estimated to be over 4.6 per 100,000 population. Before making a diagnosis, the exclusion of malignancies, lymphoma, anti-neutrophil cytoplasmic antibody-associated vasculitis, multicentric Castleman disease, and other mimickers is crucial for appropriate treatment. Broad management guidelines have been published emphasizing the need for prompt treatment and the use of glucocorticoids as first-line drug therapy for induction of remission...

A 49-year-old man was admitted to our hospital with pancreatitis. He was diagnosed with systemic lupus erythematosus at 34 years of age and was being treated with oral tacrolimus (3 mg/day) and predonine (10 mg/day) for the past 15 months. The computed tomography (CT) scan showed the mass lesion had invaded the pancreatic head via thickening of the duodenal wall. Upper gastrointestinal endoscopy showed the all-round ulcerative lesion from the superior duodenal angle to the descending portion. Histological examination confirmed the diagnosis of diffuse large B cell lymphoma (DLBCL)...

Malignant mesotheliomas are rather uncommon neoplasms associated primarily with asbestos exposure; however, they may also arise as second primary malignancies after radiation therapy, with a latency period of 15-25 years. Numerous studies have reported an association between pleural malignant mesothelioma and chest radiation performed for other malignancies; on the other hand, post-irradiation mesotheliomas of the pericardium have been reported in only a few published cases to date, and no homozygous deletion of 9p21 has been described in such cases...

Hepatitis B virus (HBV) infection is endemic in some parts of Asia, Africa and South America and remains to be a significant public health problem in these areas. It is known as a leading risk factor for the development of hepatocellular carcinoma, but epidemiological studies have also shown that the infection may increase the incidence of several types B-cell lymphoma. Here, by characterizing altogether 275 Chinese diffuse large B-cell lymphoma (DLBCL) patients, we showed that patients with concomitant HBV infection (surface antigen positive, HBsAg+ ) are characterized by a younger age, a more advanced disease stage at diagnosis and a reduced overall survival...

BACKGROUND: Prior epidemiological evidences suggest that hepatitis B virus (HBV) infection is linked to cancers other than hepatocellular carcinoma. This prospective hospital registry-based case-control study aimed to investigate the sero-epidemiological association between chronic HBV infection and various types of cancer. METHODS: 95,034 patients with first-diagnosed non-hepatocellular malignancy in a tertiary hospital between 2007 and 2014; and 118,891 non-cancer individuals as controls from a health promotion center were included...

MicroRNAs (miRNAs) are small, single-stranded, non-coding RNA molecules involved in cancer initiation and progression. The present study aimed to determine the effect of miRNA-30d (miR-30d) on the growth, malignant phenotype, and apoptosis of Ewing's sarcoma (ES) SK-ES-1 cells, and to elucidate the underlying molecular mechanism and signaling pathway involved. Cell proliferation, invasion, migration, morphological changes, cell cycle distribution and apoptosis were investigated. Furthermore, the expression of matrix metalloproteinase (MMP)-2, MMP-9, B-cell lymphoma 2 (Bcl-2), Bcl-2-associated X protein (Bax), caspase-3 and poly (ADP-ribose) polymerase (PARP) were examined, as was the activity of the mitogen-activated protein kinase kinase (MEK)/extracellular signal-regulated kinase (ERK) and phosphoinositide 3-kinase (PI3K)/Akt pathways...

Hematopoietic cell transplantation (HCT) is an established procedure for acquired and congenital disorders of the hematopoietic system. In 2016, there was a tendency for continued activity in this field with 43,636 HCT in 39,313 patients [16,507 allogeneic (42%), 22,806 autologous (58%)] reported by 679 centers in 49 countries in 2016. The main indications were myeloid malignancies 9547 (24%; 96% allogeneic), lymphoid malignancies 25,618 (65%; 20% allogeneic), solid tumors 1516 (4%; 2% allogeneic), and non-malignant disorders 2459 (6%; 85% allogeneic)...

Chimeric antigen receptor (CAR)-T cell therapy has been clinically validated as a curative treatment for the difficult to treat malignancies of relapsed/refractory B-cell acute lymphoblastic leukaemia and lymphoma. Here, the CAR-T cells are re-directed towards a single antigen, CD19, which is recognised as a virtually ideal CAR target antigen because it has strong, uniform expression on cancer cells, and is otherwise expressed only on healthy B cells, which are 'dispensable'. Notwithstanding the clinical success of CD19-CAR-T cell therapy, its single specificity has driven therapeutic resistance in 30% or more of cases with CD19-negative leukaemic relapses...

BACKGROUND: Anti-TNF (Tumor necrosis factor) therapy is effective in treating pediatric patients with refractory rheumatic disease. There is however a concern that anti-TNF usage may increase the risk of malignancy. Reports on specific types of malignancy in this patient population have been emerging over the past decade, but there is a need for additional malignancy reports, as these events are rare. Therefore, a retrospective chart review was performed on the biologic database of pediatric rheumatology patients at The Hospital for Sick Children (SickKids) from 1997 to 2013 for neoplasms, patient demographic information and rheumatologic treatment course...

Selective drug accumulation in the malignant tissue is a prerequisite for effective cancer treatment. However, most drug molecules and their formulated particles are blocked en route to the destiny tissue due to the existence of multiple biological and physical barriers including the tumor microvessel endothelium. Since the endothelial cells on the surface of the microvessel wall can be modulated by inflammatory cytokines and chemokines secreted by the tumor or stromal cells, an effective drug delivery approach is to enhance interaction between the drug particles and the unique spectrum of surface proteins on the tumor endothelium...

Purpose: Many anticancer drugs induce apoptosis in malignant cells, and resistance to apoptosis could lead to suboptimal or no therapeutic benefit. Two cytoplasmic proteins, B-cell lymphoma protein 2 (Bcl-2)-associated X (Bax) and Bcl-2, act as a promoter and an inhibitor of apoptosis, respectively. Both Bax and Bcl-2 as well as their ratio have been regarded as prognostic markers in various cancers. However, conflicting results have been reported. A clear understanding of apoptosis has also become crucial due to reports about anti-Bcl-2 chemotherapy...

To determine the risk of a wide range of second malignancies in patients with myeloproliferative neoplasms (MPNs), we conducted a large population-based study and compared the results to matched controls. From national Swedish registers, 9379 patients with MPNs diagnosed between 1973 and 2009, and 35,682 matched controls were identified as well as information on second malignancies, with follow-up until 2010. Hazard ratios (HRs) with 95 % confidence intervals (CIs) were calculated using Cox regression and a flexible parametric model...
