Recognizing the significant biologic and clinical heterogeneity of mature T-cell and NK/T-cell lymphomas, the American Society for Blood and Marrow Transplantation invited experts to develop clinical practice recommendations related to the role of auto-HCT and allo-HCT for specific histologic subtypes. We used the GRADE methodology to assist in moving from evidence to decision-making and ultimately generating final recommendations. Auto-HCT in front-line consolidation is recommended in PTCL-NOS, AITL, ALCL-ALK negative, NK/T-cell (disseminated), EATL and hepatosplenic lymphomas...

The continued use of platinum-based chemotherapeutic drugs in the clinic mandates the need for further investigation of the biological activity of structural analogues of the clinically approved complexes. Of interest are monofunctional platinum(II) complexes, which bear only one labile ligand, for which it is believed that each complex binds to DNA only once. Pyriplatin ([PtCl(NH3)2(py)](+)) and enpyriplatin ([PtCl(en)(py)](+)) are both monofunctional platinum(II) complexes that bear a pyridine ligand and a labile chlorido ligand, differing in their cis‑ammine and ethane-1,2-diamine (en) ligands respectively...

Interleukin-10 (IL-10) induces an immunosuppressive microenvironment including M2 macrophages, inhibiting anti-tumor immunity. The aim of this study was to evaluate whether serum IL-10 level at diagnosis and tissue infiltration of M2 macrophages could predict survival outcome of patients with angioimmunoblastic T-cell lymphoma (AITL).We measured serum levels of IL-5, IL-10, IL-12, and interferon-gamma (IFN-γ) at diagnosis in AITL and other common subtypes of nodal T-cell lymphoma including peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS), ALK-negative anaplastic large cell lymphoma (ALCL) or ALK-positive ALCL between September 2008 and December 2014...

It has been nearly 8 years since pralatrexate became the first drug approved by the U.S. Food and Drug Administration for the treatment of relapsed or refractory peripheral T-cell lymphoma (PTCL). Like most drugs approved for a particular clinical indication, as much or more is learned once it enters mainstream use as in the years leading up to regulatory approval. Over the past several years, many diverse lines of research have shed new insight into both the agent, and the diseases it treats. In this review, we will bring the reader up to date on the many new aspects related to pralatrexate's pharmacology, activity across the panoply of T-cell lymphoproliferative malignancies, as well as some new and emerging guidelines that are likely to improve its safety profile...

Oxidation of [Pt((II))Cl(terpy)](+) (terpy = 2,2':6',2''-terpyridine) has been attempted with several oxidizing agents and under different experimental conditions in order to obtain a Pt(iv) complex suitable for the conjugation to nanovectors to be used in drug delivery targeting for anticancer therapy. The best compromise in terms of yield and purity of the final complex was obtained by microwave-assisted reaction at 70 °C in 50% aqueous H2O2 for 2 h. Under these conditions the quantitative formation of [Pt((IV))Cl(OH)2(terpy)](+) was observed...

The Ten Eleven Translocation (TET) enzymes have been found to be mutated in both diffuse large B-cell (DLBCL) and peripheral T-cell (PTCL) lymphomas resulting in DNA hypermethylation. Recent studies in embryonal stem cells showed that ascorbic acid (AA) is a cofactor for TET with a binding site at the catalytic domain, and enhances TET activity. We hypothesized that AA could potentially enhance TET activity in lymphoma cells to cause DNA demethylation, reactivate expression of tumor suppressor genes and enhance chemosensitivity...

The complex obtained by the reaction of cisplatin and 2'-deoxyadenosine-5'-monophosphate (5'-dAMP) in water has been isolated and detected by electrospray ionization mass spectrometry. The so-formed cis-[PtCl(NH3)2(5'-dAMP)](+) complex has been studied in detail by infrared multiple photon dissociation (IRMPD) spectroscopy in two spectral ranges, namely, 700-1900 and 2800-3800 cm(-1), backed by quantum-chemical calculations at the B3LYP/LACV3P/6-311G** level of theory. In agreement with the computational results, the vibrational spectroscopic characterization of cis-[PtCl(NH3)2(5'-dAMP)](+) shows that the sampled ionic population comprises two major isomers, differentiated in the X-H stretching region by their distinct fragmentation patterns...

Despite the long history of the investigation of nucleophilic addition to metal-bound isocyanides, some important aspects of the reaction mechanism remain unclear even for the simplest systems. In this work, the addition of the sp³-N, sp²-N, and mixed sp²/sp³-N nucleophiles (i.e., HNMe₂, HN=CPh₂, and H₂N-N=CPh₂, respectively) to isocyanides C≡NR coordinated to the platinum(II) centers in the complexes cis-[Pt(C≡NCy)(2-pyz)(dppe)]⁺ (2-pyz = 2-pyrazyl, dmpe = Me₂PCH₂CH₂PMe₂) and cis-[PtCl₂(C≡NXyl)(C≡NMe)] was studied in detail by theoretical (DFT) methods...

The coordination polymers [Cu(H2O)2(μ2-NC)4PtX2] (X = Cl, Br) form networks of square grid sheets that align in a staggered manner with one another via weak X···X interactions. Upon stepwise dehydration, the layers fuse, forming a 3-D network of distorted cubes. The materials were tested for visible vapochromic, Raman, and IR response to dimethyl sulfoxide, N,N-dimethylformamide, and pyridine. Analyte-bound coordination polymers of the form Cu(analyte)2[PtX2(CN)4] were structurally characterized by PXRD and found to form layers of square grids that align through X···X interactions...

REVIEW
Piotr Smolewski, Tadeusz Robak
Romidepsin is a potent and selective inhibitor of histone deacetylases (HDCAi). It is also the only bicyclic inhibitor to undergo clinical assessment and is considered a promising drug for the treatment of T-cell lymphomas. The cellular action of romidepsin results in enhanced histone acetylation, as well as the acetylation of other nuclear or cytoplasmic proteins, influencing cell cycle, apoptosis, and angiogenesis. In phase II studies involving patients with relapsed or refractory of cutaneous T-cell lymphoma (CTCL) and peripheral T-cell lymphoma (PTCL), romidepsin produced overall response rates (ORR) of 34-35% and 25-38%, with complete response (CR) rates of 6% and 15-18%, respectively...

Globally, peripheral T-cell lymphomas (PTCLs) constitute about 12% of all non-Hodgkin lymphomas, of which the unspecified category is the most common subtype (30%). Mostly, the unspecified category shows a diffuse pattern of involvement in the lymph nodes. However, rarely, they may show a follicular/nodular pattern mimicking a follicular lymphoma. We report a case of a follicular variant of PTCL, not otherwise specified. This case displayed a striking nodular/follicular pattern with an admixture of small (centrocyte-like) and large (centroblast-like) cells, thus mimicking a follicular lymphoma...

BACKGROUND: Peripheral T-cell lymphomas (PTCLs) are non-Hodgkin's lymphomas (NHLs) with considerable variation in incidence across the world. They show a wide variety of clinicopathological features and generally associated with poor clinical outcome. Lymphoma data from different geographic regions will definitely aid in routine clinical practice and research work. PTCLs are reported with a higher frequency in Asia as compared to Western countries. OBJECTIVE: The objective of this study was to analyze the frequency and distribution of PTCLs diagnosed in a tertiary care cancer center in Kerala...

BACKGROUND: Peripheral T-cell lymphomas (PTCLs) represent a rare and heterogeneous group of malignancies that do not have consensus treatment recommendations. Strategies extrapolated from B-cell lymphoma have met with limited efficacy, although T-cell-specific salvage therapies have been recently developed. METHODS: To determine treatment patterns and associated outcomes in PTCL not otherwise specified (PTCL-NOS), anaplastic large T-cell lymphoma (ALCL), and angioimmunoblastic T-cell lymphoma (AITL), a retrospective analysis was undertaken at a large US community oncology network among patients treated between January 2010 and April 2015...

We compared the efficacy and safety of gemcitabine, cisplatin, prednisone and thalidomide (GDPT) with standard CHOP regimen (cyclophosphamide, doxorubicin, vincristine, prednisone) for patients with newly diagnosed peripheral T-cell lymphoma (PTCL) in a prospective randomized controlled and open-label clinical trial. Between July 2010 and June 2016, 103 patients were randomly allocated into two groups, of whom 52 were treated with GDPT therapy and 51 with CHOP therapy. The 2-year progression-free survival (PFS) and overall survival (OS) rates were better in the GDPT group than in the CHOP group (57% vs...

Background: Interferon regulatory factor 4 (IRF4)/multiple myeloma oncogene-1 (MUM1) is a member of the interferon regulatory factor family of transcriptional factors. Although IRF4/MUM1 expression is associated with aggressiveness of B-cell lymphoma and multiple myeloma, the prognostic value of IRF4/MUM1 expression in peripheral T-cell lymphoma (PTCL) is unclear. Methods: We analyzed a tissue array from 69 patients diagnosed with PTCL. The expression levels of IRF4/MUM1 and associated proteins such as MYC and Ikaros were analyzed by immunohistochemistry...

Peripheral T-cell lymphoma (PTCL) is a rare, heterogeneous malignancy. Of the 619 patients with relapsed and refractory (R/R) aggressive lymphoma enrolled in the Canadian Cancer Trials Group LY.12 phase 3 trial, 59 (9.5%) had PTCL. Among these, 81% had advanced stage disease, 41% had an International Prognostic Score ≥3, and 41% were refractory to primary therapy. Within the PTCL cohort, the overall response rate after two cycles of salvage chemotherapy was 36%; no difference was observed between dexamethasone, cytarabine, cisplatin (10/30, 33%), and gemcitabine, cisplatin, dexamethasone (11/29, 38%) therapy...

Di You, François P Gabbaï
With the view of developing self-activating electrophilic catalysts, we are now investigating complexes with a Lewis acidic moiety in the immediate vicinity of the transition metal center. Toward this end, we have synthesized a platinum complex in which the metal is connected to a Lewis acidic bis(triflato)stiboranyl ligand. This complex, ((o-(Ph2P)C6H4)2SbOTf2)PtCl (2), which was obtained by treatment of ((o-(Ph2P)C6H4)2SbCl2)PtCl (1) with 2 equiv of AgOTf, is surprisingly air stable. Yet, it promptly reacts with cyclohexylisocyanide to afford the dicationic chlorostibine complex [((o-(Ph2P)C6H4)2SbCl)PtCNCy](2+) ([3](2+)) as a bis-triflate salt...
