Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is a rare subtype of T-cell lymphomas with a characteristic feature of subcutaneous nodules associated with hemophagocytic lymphohistiocytosis (HLH). Treatment options for SPTCL are mainly chemotherapy (CMT) or immunosuppressive agents with selection currently dependent on physician decisions. Outcomes between the 2 treatment remedies have not yet been comprehensively compared.

Several prognostic models have been introduced to predict outcomes of patients with diffuse large B-cell lymphoma (DLBCL). Endothelial activation and stress index (EASIX) is a surrogate of endothelial dysfunction which has been shown to predict outcomes of patients with various hematologic malignancies. However, the prognostic implication of EASIX for DLBCL is limited and warrants exploration.

Article Synopsis
  • Relapsed/refractory diffuse large B-cell lymphoma (R/R DLBCL) is tough to treat, and there's a need for better therapies; polatuzumab vedotin (Pola), combined with bendamustine-rituximab (BR), has recently been approved for patients.
  • A study in Thailand included 35 patients treated with Pola, showing a 62.8% overall response rate (ORR) and survival outcomes better than 180 patients receiving non-Pola therapies.
  • Despite some serious adverse events reported, they were manageable, indicating that Pola-based treatment could be a promising option for R/R DLBCL patients with limited alternatives.

Article Synopsis
  • Acute promyelocytic leukemia (APL) is a specific type of acute myeloid leukemia (AML) that has distinct symptoms and outcomes, with this study focusing on the treatment and results for Thai patients primarily using all-trans-retinoic acid (ATRA) combined with chemotherapy.
  • Over eight years, 79 newly diagnosed APL patients were analyzed from 992 AML cases, revealing that the majority were new cases rather than therapy-related, and a significant portion showed serious symptoms like disseminated intravascular coagulation.
  • The study found a high complete response rate of 95.7%, with a four-year overall survival rate of 75.6%, but noted that older age and high white blood cell count negatively impacted survival outcomes

Multiple myeloma (MM) is an incurable plasma cell malignancy accounting for approximately 10% of hematological malignancies. Identification of reliable biomarkers for better diagnosis and prognosis remains a major challenge. This study aimed to identify potential serum prognostic biomarkers corresponding to MM disease activity and evaluate their impact on patient outcomes.

Background: Secondary acute myeloid leukemia (sAML) and AML with myelodysplasia-related changes (AML-MRC) both result in dismal outcomes. This retrospective study aimed to determine whether these features are poor prognostic factors independent of older age and adverse cytogenetics, which are commonly associated with a poor prognosis.

Methods: The characteristics and real-world outcomes of sAML and AML-MRC from the Thai AML registry database were investigated.

Article Synopsis
  • A study was conducted using data from the Thai AML registry to evaluate the effectiveness of different doses of cytarabine in treating patients with acute myeloid leukemia (AML) after achieving complete remission.
  • The median relapse-free survival (RFS) and overall survival (OS) were slightly different among the three doses (IDAC 1.5 g/m, HiDAC 2 g/m, and HiDAC 3 g/m), but no significant differences were found.
  • The study concluded that IDAC is a suitable postremission treatment, while higher doses do not offer additional benefits and may increase the risk of complications such as septic shock, emphasizing that the number of treatment cycles is more crucial than the dosage.

Background: Acute myeloid leukemia (AML) is a common, challenging hematologic malignancy worldwide. Thai data on its characteristics and outcomes have never been systematically reported, to our knowledge. The objective of this study was to determine the clinical features and outcomes of Thai patients with AML.

Event-free survival at 12 months (EFS12) is a surrogate endpoint for long-term outcomes in many histologic lymphoma subtypes. However, most reports have primarily investigated the implication of EFS12 in advanced-stage non-Hodgkin lymphoma (NHL). There are limited data regarding the significance of EFS12 in early-stage NHL.

Event free survival at 24 months (EFS24) has been described as a powerful predictor for outcome in several subtypes of B cell lymphoma. However, it was limitedly described in T cell lymphoma. We explored the implication of EFS24 as a predictor marker for peripheral T cell lymphoma (PTCL).

Adult acute lymphoblastic leukemia (ALL) is an uncommon hematologic malignancy with high relapse and mortality rate. This study aimed to describe characteristics and outcomes of Thai ALL patients, and to determine the differences between adolescent and young adult (AYA) and adult ALL. ALL patients aged > 15 years were prospectively enrolled from 2015 to 2017.

Introduction: Peripheral T cell NHL (PTCL) and natural killer/T cell NHL (NKTCL) are relatively rare disorders. Data on clinical presentation, treatment and outcome are limited especially in older age groups.

Methods: We identified 127 patients with PTCL and NKTCL, excluding cutaneous T/NK cell lymphoma, aged over 60 years old from Thailand nationwide multicenter registry.

Background: Outpatient autologous stem cell transplantations (ASCTs) in multiple myeloma and lymphoma patients have been shown to reduce the overall costs and improve the quality of life relative to inpatient ASCTs. This systematic review and meta-analysis was performed with the aim of comprehensively comparing the risk of febrile neutropenia developing in ASCT outpatients and inpatients who have multiple myeloma or lymphoma.

Methods: To be eligible for the meta-analysis, studies needed to be either randomized, controlled studies or cohort studies.

Background: Elderly patients with acute myeloid leukemia (AML) have a poorer prognosis than younger ones. Several factors contribute to the poor outcomes for this patient group.

Patients And Methods: This study investigated the epidemiology, clinical characteristics, treatment, and clinical outcomes of elderly Thai patients with AML.

Systemic reports on the descriptive epidemiology of non-Hodgkin lymphoma (NHL) from Southeast Asia are scarce. A nationwide multi-institutional registry was conducted to compare the histopathology, clinical features, and survival of Thai adult patients with NHL using large registries, especially those from Far East Asia (FEA). Using a web-based registry system, 13 major medical centers from the 4 geographic regions of Thailand prospectively collected, from 2007 to 2014, the diagnostic pathology, according to the World Health Organization classification, 2008, clinical features and survival of 4056 patients who were newly diagnosed with NHL.

Secondary central nervous system (CNS) relapse is a serious and fatal complication of diffuse large B cell lymphoma (DLBCL). Data on secondary CNS (SCNS) relapse were mostly obtained from western countries with limited data from developing countries. We analyzed the data of 2034 newly diagnosed DLBCL patients enrolled into the multi-center registry under Thai Lymphoma Study Group from setting.
