Nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) is a rare subtype of lymphoma that, like other Hodgkin lymphomas, has historically been treated aggressively. However, in most cases, NLPHL has an indolent course, which raises the question to what extent these patients require aggressive upfront treatment. We describe the management and outcomes of consecutive NLPHL patients diagnosed at Memorial Sloan Kettering Cancer Center (MSK), with a focus on evaluating active surveillance. All patients aged 16 years or older diagnosed and followed at MSK between 1974 and 2016 were included...

BACKGROUND: Allogeneic hematopoietic stem cell transplantation is one of the therapeutic options for patients with relapsed or refractory classic Hodgkins lymphoma (cHL). In the case of dis-ease relapse after transplant, other treatment options are still limited (for example donor lymphocyte infusion, and chemother-apy with brentuximab, bendamustine, or other agents) with uncertain outcomes in terms of patient tolerance and long-term dis-ease remission. One way to achieve remission is administration of the PD-1 inhibitor nivolumab, a PD-1 checkpoint inhibitor...

Colorectal cancer is the third most commonly occurring cancer in men and the second most commonly occurring cancer in women worldwide. We have recently reported that curcuminoid complexes labelled with gallium-68 have demonstrated preferential uptake in HT29 colorectal cancer and K562 lymphoma cell lines compared to normal human lymphocytes. In the present study, we report a new gallium-68-labelled curcumin derivative (68 Ga-DOTA-C21) and its initial validation as marker for early detection of colorectal cancer...

BACKGROUND: Experimental models have demonstrated that immune surveillance by cytotoxic lymphocytes can protect from spontaneous neoplasms and cancer. In humans, defective lymphocyte cytotoxicity is associated with the development of hemophagocytic lymphohistiocytosis, a hyperinflammatory syndrome. However, to the best of the authors' knowledge, the degree to which human lymphocyte cytotoxicity protects from cancer remains unclear. In the current study, the authors examined the risk of lymphoma attributable to haploinsufficiency in a gene required for lymphocyte cytotoxicity...

There is a significant overlap between intestinal lymphoproliferative disorders (LPDs) and inflammatory conditions of the intestine, including inflammatory bowel disease (IBD), in clinical, endoscopic, or histologic appearance, leading to diagnostic challenges. We report two cases of monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL) that were initially considered to be ulcerative colitis (UC) and lymphocytic colitis, respectively. Both patients presented with diarrhea and abdominal pain. Colonoscopy revealed hyperemia and scattered shallow ulcerations in the colon, without obvious mass...

Chronic lymphocytic leukemia (CLL) is the most common type of leukemia that affects older adults in the Western world. Symptomatic nervous system invasion in undiagnosed CLL is rare, poorly understood, challenging to treat, and associated with decreased survival. The average survival of CLL patients with central nervous system (CNS) involvement is 3.79 years as compared to six years in CLL patients without CNS involvement. Autopsy studies demonstrated a high incidence of undiagnosed CLL with CNS involvement, suggesting that CNS involvement is either underdiagnosed or subclinical...

Background: To summarise the evidence on the associations between body mass index (BMI) and BMI in early adulthood, height, waist circumference (WC) and waist to hip ratio (WHR), and risk of lympho-hematopoietic cancers. Method: We conducted a meta-analysis of prospective studies and identified relevant studies published up to December 2017 by searching PubMed. A random effects model was used to calculate dose-response summary relative risks (RRs). Results: Our findings showed BMI, and BMI in early adulthood (aged 18-21 years) is associated with the risk of Hodgkin's and Non-Hodgkin's lymphoma (HL and NHL), Diffuse Large Beta Cell Lymphoma (DLBCL), Leukaemia including Acute and Chronic Myeloid Lymphoma (AML and CML), and Chronic Lymphocytic Leukaemia (CLL) and Multiple Myeloma...

BACKGROUND: Adoptive immunotherapy using engineered lymphocytes has shown promising results in treating cancers even in patients who have failed other treatments. As the first essential step, the number of peripheral mononuclear cell (MNC) collection procedures is rapidly increasing. In this retrospective study, we reviewed the collection results to determine factors that affect MNC collection. STUDY DESIGN AND METHODS: We reviewed 184 collections that were performed on 169 adult allogenic donors and patients with acute lymphoid leukemia, chronic lymphoid leukemia, lymphoma, multiple myeloma, or solid-organ tumors...

Donor lymphocyte infusion (DLI) might be used prophylactically to reduce relapse after allogeneic hematopoietic stem cell transplantation for very high-risk leukemia/lymphoma without effective targeted therapy. To compare the safety and efficacy of prophylactic DLI for prevention of relapse after allogeneic peripheral blood stem cell transplantation from haploidentical donors (HID-SCT) and matched-sibling donors (MSD-SCT) in patients with very high-risk acute myeloid leukemia (AML), we performed a retrospective analysis in a cohort of 21 HID-SCT and 13 MSD-SCT recipients, displaying similar baseline characteristics except for donor's gender distribution...

The present study investigated the role of microRNA‑135a (miR‑135a) in cutaneous T‑cell lymphoma (CTCL) proliferation. Compared with the normal T lymphocyte control cell line, the mRNA and protein levels of GATA binding protein 3 (GATA‑3) were markedly increased in the Hut78 cell line and miR‑135a was markedly decreased (P<0.05). Based on bioinformatics, the target gene of miR‑135a was identified as GATA‑3. Dual luciferase and pre‑miR‑135a assays showed that miR‑135a regulated the translation of GATA‑3...

PURPOSE: Indolent non-Hodgkin lymphoma (iNHL) remains largely incurable and often requires multiple lines of treatment after becoming refractory to standard therapies. Duvelisib was approved by the Food and Drug Administration for relapsed or refractory (RR) chronic lymphocytic leukemia or small lymphocytic lymphoma (SLL) and RR follicular lymphoma (FL) after two or more prior systemic therapies. On the basis of the activity of duvelisib, a first-in-class oral dual inhibitor of phosphoinositide 3-kinase-δ,-γ, in RR iNHL in a phase I study, the safety and efficacy of duvelisib monotherapy was evaluated in iNHL refractory to rituximab and either chemotherapy or radioimmunotherapy...

Inflammatory myofibroblastic tumors (IMTs) are spindle cell neoplasms of intermediate (borderline) biologic potential with tendency for local recurrence but low risk of metastasis. They affect children more than adults. The most common sites of involvement are the lung, soft tissue, peritoneum, bladder, and less commonly the gynecologic tract. IMTs are characterized by spindle to epithelioid cells with myofibroblastic differentiation, some degree of smooth muscle differentiation, myxoid stroma and usually associated with brisk lymphoplasmacytic infiltrates...

Infections may constitute a serious complication in patients with chronic lymphocytic leukemia (CLL). New treatment agents including obinutuzumab and ibrutinib have improved the progression-free survival in CLL, and data suggest a similar overall infection risk and a limited risk of opportunistic infections when compared to standard chemo-immunotherapy. Nevertheless, cases of opportunistic infections including non-tuberculous mycobacterial (NTM) in CLL patients have recently been published. We present a case of a 74-year old man with extensive prior CLL treatment history, including most recently obinutuzumab...

BRAF mutation status is a critical predictive and prognostic biomarker in guiding management of unresectable and metastatic melanoma.1 We recently observed a case of BRAF V600E-mutated chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) intermixed with BRAF V600E wild-type melanoma reported to harbor BRAF V600E mutation on molecular testing. Our observation underscores the importance of appropriate tumor selection for molecular studies and knowledge of mutational status of co-existing tumors. This article is protected by copyright...

The bone marrow (BM) is not only a reservoir of hematopoietic stem cells but a repository of immunological memory cells. Further characterizing BM-resident memory T cells would be helpful to reveal the complicated relationship between the BM and immunological memory. In this study, we identified CD122high stem cell antigen-1 (Sca-1) high B cell lymphoma 2 (Bcl-2) high CD4+ stem cell-like memory T cells (TSCMs) as a distinct memory T cell subset, which preferentially reside in the BM, where they respond vigorously to blood-borne antigens...
