Article Synopsis
  • This study evaluates the effectiveness of two types of 19-gauge needles (conventional and Franseen) used for endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) in diagnosing lymphadenopathy and classifying malignant lymphoma.
  • It analyzed various factors, including patient characteristics, number of needle passes, and diagnostic accuracy, finding that the conventional needle required fewer passes than the Franseen needle.
  • Both needle types demonstrated high diagnostic accuracy without significant differences in outcomes, but the conventional needle is recommended for its efficiency and lower risk of adverse events.

Werner syndrome (WS) is an autosomal recessive disorder characterised by premature ageing. WS patients often experience scleroderma-like manifestation including skin sclerosis and skin ulcer, making it difficult to differentiate WS from systemic sclerosis (SSc). Moreover, there is a high incidence of malignancy and arteriosclerosis-related disease in WS patients.

Naked mole rats (NMRs) have extraordinarily long lifespans and anti-tumorigenic capability. Recent studies of humans and mice have shown that many age-related diseases, including cancer, are strongly correlated with immunity, and macrophages play particularly important roles in immune regulation. Therefore, NMR macrophages may contribute to their unique phenotypes.

Caspofungin (CPFG) is an echinocandin antifungal agent that inhibits the synthesis of β-1, 3-D-glucan, a critical component of the cell wall of target fungi. Several clinical studies have confirmed the efficacy and safety of CPFG in patients with febrile neutropenia (FN); however, there are no reports available in Japanese patients with FN. Therefore, we investigated the therapeutic efficacy and pharmacokinetics of CPFG as an empirical therapy in a Japanese hospital.

Pirarubicin (tetrahydropyranyl adriamycin [THP]) is an anthracyclin with less cardiotoxicity than doxorubicin (DOX). We previously reported the efficacy and safety of R-THP-COP consisting of rituximab (R), THP, cyclophosphamide (CPA), vincristine (VCR), and prednisolone (PSL) for diffuse large B cell lymphoma (DLBCL) in phase 2 studies. Here, we prospectively compared the efficacy and safety of the R-THP-COP and standard R-CHOP regimen (consisting of R, CPA, DOX, VCR, and PSL) in a noninferiority phase 3 trial.

Management of constipation in patients receiving cyclophosphamide, doxorubicin, vincristine and prednisolone (CHOP) or CHOP-like chemotherapy regimens is important for prevention of paralytic ileus. We reported earlier that the laxative action of magnesium oxide is reversed by the concomitant use of antacids in cancer patients receiving opioid analgesics. Here, we assessed the prevalence of prophylactic laxative medication for the control of constipation in patients receiving CHOP or CHOP-like regimens for non-Hodgkin's lymphoma.

Indoleamine 2,3-dioxygenase exerts intense immunomodulatory effects due to enzymatic activities that catalyze the breakdown of the essential amino acid l-tryptophan. The activity of indoleamine 2,3-dioxygenase can be estimated by measuring serum l-kynurenine concentrations. Here, we aimed to determine the role of l-kynurenine as a prognostic factor for peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS) in a retrospective analysis of data derived from 31 consecutive patients between June 2000 and March 2013 who were histologically diagnosed with PTCL-NOS according to the World Health Organization classification and treated with 6-8 cycles of cyclophosphamide, doxorubicin or pirarubicin, vincristine, and prednisolone.

Indoleamine 2,3-dioxygenase (IDO), a tryptophan-catabolizing intracellular enzyme of the L-kynurenine pathway, causes preneoplastic cells and tumor cells to escape the immune system by inducing immune tolerance; this mechanism might be associated with the development and progression of human malignancies. In the present study, we investigated the role of IDO in diethylnitrosamine (DEN)-induced hepatocarcinogenesis by using IDO-knockout (KO) mice. To induce hepatocellular carcinoma (HCC), hepatic adenoma, and preneoplastic hepatocellular lesions termed foci of cellular alteration (FCA), male IDO-wild-type (WT) and IDO-KO mice with a C57BL/6J background received a single intraperitoneal injection of DEN at 2 weeks of age.
