Natural killer/T-cell lymphoma is rare and aggressive, with poor outcome. Optimal treatment remains unclear. A novel regimen dexamethasone, methotrexate, ifosfamide, l-asparaginase, and etoposide (SMILE) showed promise in phase 1/2 studies with restrictive recruitment criteria. To define the general applicability of SMILE, 43 newly diagnosed and 44(More)
BACKGROUND Platelets have been reported to act as transporters of tumor-originated vascular endothelial growth factor (VEGF), contributing to tumor angiogenesis and progression. Serum VEGF per platelet count, as an indirect theoretical estimate of VEGF in platelets, may predict the malignant potential of tumors. However, its prognostic significance is still(More)
The molecular mechanisms underlying angioimmunoblastic T cell lymphoma (AITL), a common type of mature T cell lymphoma of poor prognosis, are largely unknown. Here we report a frequent somatic mutation in RHOA (encoding p.Gly17Val) using exome and transcriptome sequencing of samples from individuals with AITL. Further examination of the RHOA mutation(More)
BACKGROUND Hypoxia-induced changes may allow tumor cells to survive under sustained hypoxic microenvironments resulting in achievement of more aggressive phenotypes. The purpose of this study is to determine the prognostic relevance of the expression of carbonic anhydrase IX (CA IX), a hypoxia-related protein in surgically resected squamous cell carcinoma(More)
PURPOSE Effective and less aggressive therapies are required for patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) who are not eligible for or have undergone autologous stem-cell transplantation (ASCT). The present phase II study assessed the efficacy and safety of bendamustine plus rituximab (BR) in this population. PATIENTS AND(More)
OBJECTIVES B-cell activating factor of the tumor necrosis factor family (BAFF) and a proliferation-inducing ligand (APRIL) regulate survival and proliferation of B cells. Thus the association of elevated serum levels of BAFF and APRIL with worse prognosis has been suggested in B-cell lymphoid malignancies. However, the prognostic relevance of BAFF and APRIL(More)
Endogenous hypoxia markers have been studied as prognostic indicators because they appear to be associated with tumor aggressiveness. This study was undertaken to compare the expression of two endogenous hypoxia markers, Hypoxia-inducible factor-1alpha (HIF-1alpha) and carbonic anhydrase IX (CA IX), with regard to their prognostic significance. We also(More)
Urokinase plasminogen activator receptor (uPAR) plays a major role in cancer invasion and metastasis and uPAR expression is correlated with a poor prognosis in various cancer types. Moreover, the expression of uPAR is increased under hypoxic conditions. Nitric oxide (NO) and its metabolites produced by inducible nitric oxide synthase (iNOS) are important(More)
PURPOSE To report treatment outcomes after combined-modality therapy in patients with Stage I/II head-and-neck (HN) diffuse large B cell lymphoma (DLBL). METHODS AND MATERIALS Eighty-six eligible patients received sequential chemotherapy and involved-lesion radiation therapy from 1995 to 2006. After a median of four cycles of CHOP (cyclophosphamide,(More)
Pulmonary marginal zone B-cell lymphoma of the MALT type (P-MZL) is a relatively rare form of lymphoma. We conducted a retrospective analysis of the clinical features and treatment outcomes of P-MZL for the evaluation of prognostic factors, and to collect information about the optimal treatment modality for this condition. From 1991 to 2008, a total of 61(More)
