Feasibility of thiotepa addition to the fludarabine-busulfan conditioning with tacrolimus/sirolimus as graft vs host disease prophylaxis.
In classical reduced-intensity conditioning (RIC) regimens, including the fludarabine and busulphan (BF) combination, sirolimus and tacrolimus (SIR-TAC) as graft vs host disease (GVHD) prophylaxis has shown acceptable results. The outcomes of SIR-TAC in a more intense RIC regimen as Thiotepa-fludarabine-busulfan (TBF) have been hardly investigated. ⋯ There were no significant differences in the cumulative incidence of grade II-IV acute GVHD or moderate-severe chronic GVHD or relapse between both groups. These results suggest that TBF does not seem to improve the traditional RIC BF regimen, at least when associated with SIR-TAC prophylaxis.

lncRNA SNHG14 promotes oncogenesis and immune evasion in diffuse large-B-cell lymphoma by sequestering miR-152-3p.
This study aimed to explore the role of small nucleolar RNA host gene 14 (SNHG14) in the pathogenesis of diffuse large-B-cell lymphoma (DLBCL). DLBCL cell lines (OCI-Ly7 and OCI-Ly3) and specimens from patients were collected to evaluate the roles of SNHG14 in DLBCL pathogenesis. The results showed that SNHG14 expression increased and miR-152-3p expression decreased in DLBCL tissues and cell lines, indicating a negative correlation between miR-152-3p and SNHG14 expression. ⋯ Additionally, SNHG14/miR-152-3p inhibits apoptosis and promotes cell proliferation on cytotoxic T lymphocytes (CTLs) in DLBCL via the PD-1/PD-L1 checkpoint. Furthermore, both the immune escape and progression of DLBCL are advanced by SNHG14 expression via its interactions with miR-152-3p. Collective, this suggests that SNHG14 is a potential diagnostic, prognostic, and therapeutic target for DLBCL.

Randomized Controlled Trial Multicenter StudyObinutuzumab plus chemotherapy followed by obinutuzumab monotherapy is cost-effective vs. rituximab plus chemotherapy followed by rituximab monotherapy for previously untreated follicular lymphoma patients in the United States.
The GALLIUM trial compared obinutuzumab (GA101, G)-based chemotherapy followed by G monotherapy (G + chemo) for up to two years to rituximab (R)-based chemotherapy followed by R monotherapy (R + chemo) for up to two years in previously untreated follicular lymphoma (FL) patients. We estimated the cost-effectiveness of G + chemo versus R + chemo utilizing GALLIUM trial data and published literature. G + chemo had increased drug costs (undiscounted: $135,200 versus $127,700 for R + chemo), representing a relative increase of 5.9%. ⋯ G + chemo led to increased quality-adjusted life years (QALYs) relative to R + chemo of 0.81 (95% credible range, [CR]: 0.22-1.37), and the overall discounted incremental cost was $1,900 (95% CR: -$7,400 to $8,900). The incremental cost-effectiveness ratio was ∼$2,300 per QALY gained, and the results were highly robust to sensitivity analyses. Treatment with G + chemo compared to R + chemo is cost-effective in previously untreated FL patients in the US.

Randomized Controlled Trial Multicenter StudyCharacterizing the kinetics of lymphocytosis in patients with chronic lymphocytic leukemia treated with single-agent ibrutinib.
Increased absolute lymphocyte count (ALC) is a key feature of chronic lymphocytic leukemia (CLL) but is also observed during treatment with B-cell receptor pathway inhibitors including ibrutinib, a first-in-class inhibitor of Bruton's tyrosine kinase. In patients with CLL treated with single-agent ibrutinib in two multicenter, open-label, randomized, phase 3 studies (RESONATE-2, NCT01722487; RESONATE, NCT01578707), lymphocytosis was observed in 77 of 136 (57%) patients treated in first-line and 133 of 195 (69%) relapsed/refractory patients. ⋯ Lymphocytosis is a common and predictable pharmacodynamic effect of ibrutinib treatment, and in the absence of other signs of progression, does not represent disease progression. Lymphocytosis resolves in the majority of patients and does not require interruption or discontinuation of ibrutinib therapy.
