Combination of rituximab and methotrexate followed by rituximab and cytarabine in elderly patients with primary central nervous system lymphoma.

The optimal treatment strategy for newly diagnosed primary central nervous system lymphoma (PCNSL) has yet to be established, especially in the elderly. In the current study, we conducted a phase II study to evaluate the efficacy and safety of rituximab plus high-dose MTX followed by rituximab plus cytarabine in patients aged ≥60 years newly diagnosed with PCNSL. Patients received an induction treatment of high-dose methotrexate plus rituximab followed by two cycles of a consolidation treatment of cytarabine plus rituximab.

Clinical Efficacies of FLT3 Inhibitors in Patients with Acute Myeloid Leukemia.

FLT3 mutations are the most common genomic alteration detected in acute myeloid leukemia (AML) with a worse clinical prognosis. The highly frequent FLT3 mutations, together with the side effects associated with clinical prognosis, make FLT3 promising treatment targets and have provoked the advancement of FLT3 inhibitors. Recently, numerous FLT3 inhibitors were actively developed, and thus the outcomes of this aggressive subtype of AML were significantly improved.

Targeted Therapeutic Approach Based on Understanding of Aberrant Molecular Pathways Leading to Leukemic Proliferation in Patients with Acute Myeloid Leukemia.

Acute myeloid leukemia (AML) is a heterogenous hematopoietic neoplasm with various genetic abnormalities in myeloid stem cells leading to differentiation arrest and accumulation of leukemic cells in bone marrow (BM). The multiple genetic alterations identified in leukemic cells at diagnosis are the mainstay of World Health Organization classification for AML and have important prognostic implications. Recently, understanding of heterogeneous and complicated molecular abnormalities of the disease could lead to the development of novel targeted therapeutic agents.

A phase II trial of bendamustine, carboplatin, and dexamethasone for refractory or relapsed peripheral T-cell lymphoma (BENCART trial).

This trial was designed to investigate the efficacy and toxicity of bendamustine, carboplatin, and dexamethasone (BCD) for relapsed or refractory peripheral T-cell lymphomas (PTCLs), which would be expected to exhibit more promising clinical outcomes compared with bendamustine therapy alone. After treatments with BCD, eight patients exhibited a complete response (CR; 29%) and seven exhibited a partial response (PR; 25%). The overall response rate (ORR) was 54%.

Understanding Immune Evasion and Therapeutic Targeting Associated with PD-1/PD-L1 Pathway in Diffuse Large B-cell Lymphoma.

In tumor microenvironment, the programmed death 1 (PD-1) immune checkpoint has a crucial role of mechanism of T cell exhaustion leading to tumor evasion. Ligands of PD-1, programmed death ligand 1/2 (PD-L1/L2) are over-expressed in tumor cells and participate in prolonged tumor progression and survivals. Recently, clinical trials for patients who failed to obtain an optimal response prior to standardized chemotherapy in several solid cancers have been focused on targeting therapy against PD-1 to reduce disease progression rates and prolonged survivals.

Treating synchronous bilateral ocular adnexal marginal zone lymphoma: the consortium for improving survival of lymphoma study.

Both-side synchronous involvement has been reported to account for 7-24% of ocular adnexal marginal zone lymphoma (OAML). We conducted a retrospective analysis to identify the clinical features and treatment outcomes of synchronous bilateral OAML (SB-OAML) by treatment modality. We analyzed patients with a histologic diagnosis of SB-OAML, excluding metachronous bilateral involved OAML.

Antitumoral effect of arsenic compound, sodium metaarsenite (KML001), on multiple myeloma cells.

KML001 (sodium metaarsenite;NaAs2O3) is known to have antitumor activity against a variety of cancers. In this study, we examined its effect on multiple myeloma (MM). KML001 reduced the growth of all MM cell lines examined with an IC50 of 5x10‑8 M.

Antiemetic Corticosteroid Rotation from Dexamethasone to Methylprednisolone to Prevent Dexamethasone-Induced Hiccup in Cancer Patients Treated with Chemotherapy: A Randomized, Single-Blind, Crossover Phase III Trial.

Background: To assess whether the rotation of dexamethasone to methylprednisolone decreases the intensity of dexamethasone-induced hiccup (DIH) in cancer patients treated with chemotherapy.

Materials And Methods: Adult patients who experienced DIH within 3 days after the administration of dexamethasone as an antiemetic were screened. Eligible patients were randomly assigned to receive dexamethasone ( = 33) or methylprednisolone ( = 32) as an antiemetic (randomization phase).

Multicenter Retrospective Analysis of Clinical Characteristics, Treatment Patterns, and Outcomes in Very Elderly Patients with Diffuse Large B-Cell Lymphoma: The Korean Cancer Study Group LY16-01.

Safety and efficacy of single-agent docetaxel (Taxotere) administered weekly in non-small cell lung carcinoma patients in Korea: An observational study.

Background: To investigate the efficacy, safety, and tolerability of weekly docetaxel treatment in advanced non-small cell lung cancer (NSCLC) patients in Korea.

Methods: This prospective observational study included Korean advanced NSCLC patients with Eastern Cooperative Oncology Group performance status <2 who received weekly monotherapy of docetaxel at a dose determined by the physician. Efficacy measurements included tumor response rate, overall survival (OS), progression-free survival, and one-year survival rate.

The potential of deferasirox as a novel therapeutic modality in gastric cancer.

Background: Iron is a crucial element for cell proliferation, growth, and metabolism. However, excess iron and altered iron metabolism are both associated with tumor initiation and tumor growth. Deferasirox is an oral iron chelator.

Anti-tumoral effect of arsenic compound, sodium metaarsenite (KML001), in non-Hodgkin's lymphoma: an in vitro and in vivo study.

Arsenic compounds have been used in traditional medicine for several centuries. KML001 (sodium metaarsenite; NaAsO2) is an orally bio-available arsenic compound with potential anti-cancer activity. However, the effect of KML001 has not been studied in lymphoid neoplasms.

Prediction of survival by applying current prognostic models in diffuse large B-cell lymphoma treated with R-CHOP followed by autologous transplantation.

Background: Among the currently available prognostic models for diffuse large B-cell lymphoma (DLBCL), we investigated to determine which is most adoptable for DLBCL patients treated with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) followed by upfront autologous stem cell transplantation (auto-SCT).

Methods: We retrospectively evaluated survival differences among risk groups based on the International Prognostic Index (IPI), the age-adjusted IPI (aaIPI), the revised IPI (R-IPI), and the National Comprehensive Cancer Network IPI (NCCN-IPI) at diagnosis in 63 CD20-positive DLBCL patients treated with R-CHOP followed by upfront auto-SCT.

Results: At the time of auto-SCT, 74.

Salvage chemotherapy of gemcitabine, dexamethasone, and cisplatin (GDP) for patients with relapsed or refractory peripheral T-cell lymphomas: a consortium for improving survival of lymphoma (CISL) trial.

There is no standard salvage chemotherapy for relapsed or refractory peripheral T-cell lymphomas (PTCLs). Gemcitabine combined with cisplatin has been known as an effective regimen for lymphoma treatment in the salvage setting. We investigated the efficacy and toxicity of gemcitabine, dexamethasone, and cisplatin (GDP) for relapsed or refractory PTCLs in search of a more effective and less toxic therapy.

Sodium metaarsenite (NaAs2O3: code name KML001) is an orally bioavailable arsenic compound with potential anti-cancer activity. However, the effect of KML001 has not been studied in acute myeloid leukemia (AML). We investigated the anti-leukemic effect of KML001 in AML, and determined the mode of action of KML001.

Retrospective analysis of extra-gastrointestinal stromal tumors.

Aim: To investigate the clinicopathologic features of patients with extra-gastrointestinal stromal tumors (EGISTs) in South Korea.
