Pembrolizumab-induced simultaneous and multiple immune-related adverse events including myasthenia gravis, myositis, hepatitis, and pityriasis lichenoides in a non-small cell lung cancer patient.

Pembrolizumab, an immune checkpoint inhibitor (ICI) targeting the programmed cell death protein 1 (PD-1) receptor on T cells, enhances the immune system's ability to recognize and attack cancer cells. However, immune-related adverse events (irAEs) may arise, necessitating careful monitoring during treatment. Here, we present the case of a 47-year-old woman who developed multiple irAEs following pembrolizumab therapy.

Early dose reduction of dasatinib does not compromise clinical outcomes in patients with chronic myeloid leukemia: A comparative analysis of two prospective trials.

Dasatinib is a potent second-generation tyrosine kinase inhibitor (TKI) used as a first-line treatment option for patients with chronic myeloid leukemia (CML). Currently, dose modification due to adverse events (AEs) is common in patients treated with dasatinib. This study compared the outcomes of two sequential prospective trials that enrolled patients with newly diagnosed chronic phase of CML (CP-CML) and initiated dasatinib at a starting dose of 100 mg daily.

Risk stratification for early mortality in newly diagnosed acute promyelocytic leukemia: a multicenter, non-selected, retrospective cohort study.

Introduction: Despite the current effective treatments for acute promyelocytic leukemia (APL), early mortality (EM), defined as death within 30 days of presentation, is a major hurdle to long-term survival.

Methods: We performed a multicenter retrospective study to evaluate the incidence and clinical characteristics of EM in patients with newly diagnosed APL and to develop a risk stratification model to predict EM.

Results: We identified 313 eligible patients diagnosed between 2000 and 2021 from five academic hospitals.

Geriatric risk model for older patients with diffuse large B-cell lymphoma (GERIAD): a prospective multicenter cohort study.

Background/aims: Optimal risk stratification based on simplified geriatric assessment to predict treatment-related toxicity and survival needs to be clarified in older patients with diffuse large B-cell lymphoma (DLBCL).

Methods: This multicenter prospective cohort study enrolled newly diagnosed patients with DLBCL (≥ 65 yr) between September 2015 and April 2018. A simplified geriatric assessment was performed at baseline using Activities of Daily Living (ADL), Instrumental ADL (IADL), and Charlson's Comorbidity Index (CCI).

Acute myelomonocytic leukemia and T-lymphoblastic lymphoma as simultaneous bilineage hematologic malignancy treated with decitabine: A case report.

Background: Simultaneous bilineage hematologic malignancies are rare; however, several cases of acute myeloid leukemia (AML) and T-lymphoblastic lymphoma (T-LBL) co-occurrence have been reported. A standard treatment for simultaneous AML and T-LBL has not yet been established, and its prognosis is very poor. Further studies to develop standard treatments are required to increase patient survival rates.

Intensified First Cycle of Rituximab Plus Eight Cycles of Cyclophosphamide, Doxorubicin, Vincristine, and Prednisolone with Rituximab Chemotherapy for Advanced-Stage or Bulky Diffuse Large B-Cell Lymphoma: A Multicenter Phase II Consortium for Improving Survival of Lymphoma (CISL) Study.

Purpose: This phase II, open-label, multicenter study aimed to investigate the efficacy and safety of a rituximab intensification for the 1st cycle with every 21-day of rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP-21) among patients with previously untreated advanced-stage or bulky diffuse large B-cell lymphoma (DLBCL).

Materials And Methods: Ninety-two patients with stage III/IV or bulky DLBCL from 21 institutions were administered 8 cycles of R-CHOP-21 with an additional one dose of rituximab intensification on day 0 of the 1st cycle (RR-CHOP). The primary endpoint was a complete response (CR) rate after 3 cycles of chemotherapy.

Introduction: This prospective study aimed to investigate the efficacy and safety of preemptive antiviral therapy with tenofovir disoproxil fumarate (TDF) for HBsAg-positive patients with newly diagnosed diffuse large B-cell lymphoma receiving rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) chemotherapy.

Methods: We enrolled 73 patients from 20 institutions. The primary end point was the absolute risk of hepatitis B virus (HBV)-related hepatitis during preemptive TDF therapy and for 24 weeks after withdrawal from TDF.

Bendamustine Plus Rituximab for Mantle Cell Lymphoma: A Korean, Multicenter Retrospective Analysis.

Background/aim: The combination of bendamustine and rituximab (BR) is highly effective in both treatment-naïve and relapsed or refractory mantle cell lymphoma (MCL). Due to the rarity of MCL and limited accessibility of BR, clinical outcome from BR in the routine clinical practice in Korean patients are limited.

Patients And Methods: To evaluate the real-world outcomes of BR treatment for MCL in Korea, medical records from 37 patients were retrospectively analyzed.

Busulfan, Melphalan, and Etoposide (BuME) Showed an Equivalent Effect to Busulfan, Cyclophosphamide, and Etoposide (BuCE) as Conditioning Therapy for Autologous Stem Cell Transplantation in Patients with Relapsed or High-Risk Non-Hodgkin's Lymphoma: A Multicenter Randomized Phase II Study bythe Consortium for Improving Survival of Lymphoma (CISL).

Purpose: High-dose chemotherapy followed by autologous stem cell transplantation (ASCT) is the standard management for relapsed or high-risk non-Hodgkin's lymphoma (NHL). We reported the busulfan, melphalan, and etoposide (BuME) conditioning regimen was effective in patients with relapsed or high-risk NHL. Moreover, the busulfan, cyclophosphamide, and etoposide (BuCE) conditioning regimen has been used widely in ASCT for NHL.

Disseminated soft tissue diffuse large B-cell lymphoma involving multiple abdominal wall muscles: A case report.

Background: Diffuse large B-cell lymphoma (DLBCL) is the most common subtype of non-Hodgkin lymphoma, and patients with DLBCL typically present rapidly growing masses. Lymphoma involving muscle is rare and accounts for only 5%; furthermore, multiple muscles and soft tissue involvement of DLBCL is unusual. Due to unusual clinical manifestation, accurate diagnosis could be delayed.

Multicenter, phase II study of response-adapted lenalidomide-based therapy for transplant-ineligible patients with newly diagnosed multiple myeloma without high-risk features.

Lenalidomide and low-dose dexamethasone (Rd) are a standard treatment for older adults with multiple myeloma (MM). Lenalidomide monotherapy has rarely been evaluated for newly diagnosed transplant-ineligible MM patients. This multicenter phase II trial evaluated a response-adapted strategy for elderly patients with newly diagnosed MM without high-risk features.

Adjuvanted recombinant zoster vaccine in adult autologous stem cell transplant recipients: polyfunctional immune responses and lessons for clinical practice.

Immunocompromised individuals, particularly autologous hematopoietic stem cell transplant (auHSCT) recipients, are at high risk for herpes zoster (HZ). We provide an in-depth description of humoral and cell-mediated immune (CMI) responses by age (protocol-defined) or underlying disease (post-hoc) as well as efficacy by underlying disease (post-hoc) of the adjuvanted recombinant zoster vaccine (RZV) in a randomized observer-blind phase III trial (ZOE-HSCT, NCT01610414). 1846 adult auHSCT recipients were randomized to receive a first dose of either RZV or placebo 50-70 days post-auHSCT, followed by the second dose at 1-2 months (M) later.

Comprehensive analysis of peripheral T-cell and natural killer/T-cell lymphoma in Asian patients: A multinational, multicenter, prospective registry study in Asia.

Background: Peripheral T-cell lymphomas (PTCLs) are uncommon and their frequency is regionally heterogeneous. Several studies have been conducted to evaluate the clinical features and treatment outcomes of this disease entity, but the majority of these were conducted in limited areas, making it difficult to comprehensively analyze their relative frequency and clinical features. Furthermore, no consensus treatment for PTCLs has been established.

Cutaneous T-cell lymphoma in Asian patients: a multinational, multicenter, prospective registry study in Asia.

Cutaneous T-cell lymphomas (CTCLs) are a group of T-cell lymphomas with low incidence. Due to their indolent characteristics, treatment strategies have not yet been established for advanced CTCLs. In this study, relative incidence of CTCLs in Asia was estimated and the therapeutic outcomes presented based on various treatments currently used in clinics for advanced CTCLs.

First-Line Treatment for Primary Breast Diffuse Large B-Cell Lymphoma Using Immunochemotherapy and Central Nervous System Prophylaxis: A Multicenter Phase 2 Trial.

There are limited data from prospective controlled trials regarding optimal treatment strategies in patients with primary breast diffuse large B-cell lymphoma (DLBCL). In this phase 2 study (NCT01448096), we examined the efficacy and safety of standard immunochemotherapy and central nervous system (CNS) prophylaxis using intrathecal methotrexate (IT-MTX). Thirty-three patients with newly diagnosed primary breast DLBCL received six cycles of rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) and four fixed doses of IT-MTX (12 mg).

Intravenous busulfan and melphalan versus high-dose melphalan as a conditioning regimen for early autologous stem cell transplantation in patients with multiple myeloma: a propensity score-matched analysis.

We compared the efficacy and toxicity of busulfan and melphalan (BUMEL) and those of high-dose melphalan (HDMEL) as conditioning regimens for autologous stem cell transplantation (ASCT) in patients with multiple myeloma (MM) through a propensity score-matched analysis. No significant difference in the complete response and overall response rate after ASCT was observed between BUMEL and HDMEL. After a median follow-up of 37.

Treatment with intravenous busulfan, melphalan, and etoposide followed by autologous stem cell transplantation in patients with non-Hodgkin's lymphoma: a multicenter study from the consortium for improving survival of lymphoma.

Several high-dose therapy (HDT) conditioning regimens have been used to treat non-Hodgkin's lymphoma (NHL), such as bis-chloroethylnitrosourea (BCNU)/etoposide/cytosine arabinoside/melphalan (BEAM), BCNU/etoposide/cytosine arabinoside/cyclophosphamide (BEAC), and cyclophosphamide/BCNU/etoposide (CBV). BCNU is an active drug in HDT of NHL, but the supply is limited in some countries, including Korea. Busulfan has been used in allogeneic and autologous stem cell transplantation (ASCT).
