Peripheral blood lymphocytes of a patient with follicular B-cell non- Hodgkin's lymphoma (B-NHL) were immortalized in vitro by Epstein-Barr virus (EBV). Eight cell lines were obtained (termed BNS1, BNS2–1 through BNS2–7), which showed a pattern of idiotypic (id) Ig surface expression and Ig JH and kappa gene rearrangement, identical to that of the parent cells (termed NS), confirming their neoplastic origin. Induction of allogeneic T-cell proliferation by NS cells was mediated by HLA-DR, leukocyte function-associated antigen-1 (LFA-1), LFA-3, B7–1/CD80, and CTLA4 and resulted in the upregulation (LFA-3, intercellular adhesion molecule-1 [ICAM-1], CD40) and induction (B7–1/CD80, B7–2/CD86, L16/activated LFA-1) of accessory molecules on NS cells. In turn, responder T lymphocytes were induced to express B7–1/CD80, B7–2/CD86, CD40 ligand (CD40L), ICAM-1, L16/activated LFA-1, and HLA-DR, reflecting bidirectional signaling between T lymphocytes and B-NHL cells. Preactivation of NS cells by EBV transformation or CD40 engagement resulted in enhanced expression of accessory molecules and abolished the requirement for accessory cells during allostimulation. These resting and activated clonal B cells will be useful in further dissecting the requirements for B-NHL costimulation.

Abstract Less than 60% of patients with B-cell non-Hodgkin’s lymphoma (B-NHL) can be cured with contemporary therapy. Using artificial receptors it is possible to redirect the specificity of immune cells to tumor-associated antigens, a strategy that holds great potential as a novel cancer therapy. Since B-NHL cells invariably express CD19, we transduced human peripheral blood T lymphocytes with a recently developed receptor (anti-CD19-BB-ζ), which consists of the single-chain variable domain (scFv) of an anti-CD19 monoclonal antibody, the hinge and transmembrane domains of CD8α, and the signaling domains of CD3ζ and 4-1BB. CD3ζ delivers the primary stimulus upon receptor engagement, while 4-1BB delivers co-stimulatory signals that are crucial for T-cell cytotoxicity. It has been shown that elicitation of 4-1BB signaling enhances the immune response to tumors in vivo, even when an immune response cannot be induced by CD28 stimulation. Retroviral transduction led to anti-CD19-BB-ζ expression in T cells with high efficiency: median percent of transduced cells was 60.3% (range, 25.7%–83.4%; n = 9). T lymphocytes expressing anti-CD19-BB-ζ expanded more vigorously that T cells transduced with receptors lacking 4-1BB and exerted powerful cytotoxicity against the CD19+ B-NHL cell lines Raji, Daudi, RL, and HT in vitro: at a 0.5: 1 effector: target ratio, mean (± SD) cell specific lymphoma cell killing was 96.6% ± 4.6% after 5–7 days of culture (4 experiments in each cell line). Transduced T cells were also effective against freshly isolated cells from patients with diffuse large, follicular large, Burkitt, and mantle cell lymphoma cultured on bone marrow-derived mesenchymal cells: in 10 samples, cell killing was 93.6% ± 5.7% at a 0.5: 1 ratio after 5–7 days of culture. Sensitivity to anti-CD19-BB-ζ-mediated killing was observed regardless of high Bcl-2 expression. T cells expressing anti-CD19-BB-ζ were also effective in a xenograft model of NHL, in which NOD/SCID mice were inoculated subcutaneously with lymphoma cells (1 x 107). Subsequent inoculation of T cells (2 x 106) transduced with anti-CD19-BB-ζ receptors significantly suppressed tumor growth, whereas inoculation of T cells transduced with empty control vector had no effect (3 mice for each treatment). These results provide a rationale for clinical testing of autologous T cells modified with anti-CD19-BB-ζ receptors in patients with aggressive or relapsed B-NHLs refractory to conventional therapy.

Tumor-infiltrating T lymphocytes (TIL-T) are always present in B-cell- derived non-Hodgkin's lymphoma (NHL). In this investigation, we explored the possibility that collaboration might exist between these cells. TIL-T were isolated from 39 lymph nodes of patients with NHL. In most of the cases, few of them (less than 10%) possessed surface activation receptors CD25 or OKT9. In 80% of the cases, they proliferated in response to recombinant interleukin-2 (rIL-2), but the degree of proliferation was often low as compared with control populations. The influence of irradiated autologous malignant cells on the TIL-T proliferation in response to rIL-2 (40 U/mL) was also investigated: in 38% of the cases, this proliferation was not modified (group O), and in 41% it was higher (group +) and in 21% it was lower (group -). The mechanism of this immune response (specific or not) is not elucidated at present. The definition of these groups was statistically correlated with different parameters of the disease: (1) percentage of TIL-T was higher in group + (44% +/- 17%) than in group O (31% +/- 18%) and group - (24% +/- 15%); (2) B-cell proliferation in centrofollicular lymphomas was more frequently nodular or nodular and diffuse in group + (83%) and O (55%) than in group - (0%); (3) low- grade malignancies in the Working Formulation were more frequent in group + (75%) than in group O (60%) or group - (12%); (4) favorable prognosis evaluated with the Grenoble cytologic classification was more frequent in group + and O (87%) than in group - (12%); (5) actuarial survival curves showed a significantly better prognosis for patients in group +.

BackgroundNon-Hodgkin’s lymphoma (NHL) is currently the most common malignancy among people living with HIV (PLWH) in the USA. NHL in PLWH is more frequently associated with oncogenic viruses than NHL in immunocompetent individuals and is generally associated with increased PD-1 expression and T cell exhaustion. An effective immune-based second-line approach that is less immunosuppressive than chemotherapy may decrease infection risk, improve immune control of oncogenic viruses, and ultimately allow for better lymphoma control.MethodsWe conducted a retrospective study of patients with HIV-associated lymphomas treated with pembrolizumab±pomalidomide in the HIV and AIDS Malignancy Branch, Center for Cancer Research, National Cancer Institute.ResultsWe identified 10 patients with stage IV relapsed and/or primary refractory HIV-associated NHL who were treated with pembrolizumab, an immune checkpoint inihibitor, with or without pomalidomide. Five patients had primary effusion lymphoma (PEL): one had germinal center B cell-like (GCB) diffuse large B cell lymphoma (DLBCL); two had non-GCB DLBCL; one had aggressive B cell lymphoma, not otherwise specified; and one had plasmablastic lymphoma. Six patients received pembrolizumab alone at 200 mg intravenously every 3 weeks, three received pembrolizumab 200 mg intravenously every 4 weeks plus pomalidomide 4 mg orally every day for days 1–21 of a 28-day cycle; and one sequentially received pembrolizumab alone and then pomalidomide alone. The response rate was 50% with particular benefit in gammaherpesvirus-associated tumors. The progression-free survival was 4.1 months (95% CI: 1.3 to 12.4) and overall survival was 14.7 months (95% CI: 2.96 to not reached). Three patients with PEL had leptomeningeal disease: one had a complete response and the other two had long-term disease control. There were four immune-related adverse events (irAEs), all CTCAEv5 grade 2–3; three of the four patients were able to continue receiving pembrolizumab. No irAEs occurred in patients receiving the combination of pembrolizumab and pomalidomide.ConclusionsTreatment of HIV-associated NHL with pembrolizumab with or without pomalidomide elicited responses in several subtypes of HIV-associated NHL. This approach is worth further study in PLWH and NHL.

Abstract Little is known about the expression of bcl-2 protein in intermediate and high grade non-Hodgkin's lymphoma (NHL) and its clinical and prognostic significance. We performed immunohistochemical analysis of bcl-2 expression in tumoral tissue sections of 348 patients with high or intermediate grade NHL. These patients were uniformly treated with adriamycin, cyclophosphamide, vindesine, bleomycin, and prednisone (ACVBP) in the induction phase of the LNH87 protocol. Fifty eight cases were excluded due to inadequate staining. Of the 290 remaining patients, 131 (45%) disclosed homogeneous positivity (high bcl-2 expression) in virtually all tumor cells, whereas 65 (23%) were negative and 94 (32%) exhibited intermediate staining. High bcl-2 expression was more frequent in B-cell NHL (109 of 214, 51%) than in T- cell NHL (6 of 35, 17%) (P = .0004), and was heterogeneously distributed among the different histological subtypes. Further analysis was performed on the 151 patients with diffuse large B-cell lymphoma (centroblastic and immunoblastic) to assess the clinical significance and potential prognostic value of bcl-2 expression in the most frequent and homogeneous immunohistological subgroup. High bcl-2 expression, found in 44% of these patients (67 of 151), was more frequently associated with III-IV stage disease (P = .002). Reduced disease-free survival (DFS) (P < .01) and overall survival (P < .05) were demonstrated in the patients with high bcl-2 expression. Indeed, the 3-year estimates of DFS and overall survival were 60% and 61%, respectively (high bcl-2 expression) versus 82% and 78%, respectively (negative/intermediate bcl-2 expression). A multivariate regression analysis confirmed the independent effect of bcl-2 protein expression on DFS. Thus bcl-2 protein expression, as demonstrated in routinely paraffin-embedded tissue, appears to be predictive of poor DFS, in agreement with the role of bcl-2 in chemotherapy-induced apoptosis. It might be considered as a new independent biologic prognostic parameter, which, especially in diffuse large B-cell NHL, could aid in the identification of patient risk groups.

Added to standard chemotherapy, rituximab improved survival in patients with non-Hodgkin's lymphoma; added to fludarabine-based regimens, it improved response and survival in patients with chronic B-cell lymphocytic leukemia.
