Poor Applicability of Currently Available Prognostic Scoring Systems for Prediction of Outcome in KIT D816V-Negative Advanced Systemic Mastocytosis.

Within our nationwide registry, we identified a KIT D816V mutation (KIT D816Vpos.) in 280/299 (94%) patients with advanced systemic mastocytosis (AdvSM). Age, cytopenias and the presence of additional somatic mutations confer inferior overall survival (OS). However, little is known about the characteristics of KIT D816V-negative (D816Vneg.) AdvSM. In 19 D816Vneg. patients, a combination of clinical, morphological and genetic features revealed three subgroups: (a) KIT D816H- or Y-positive SM (KIT D816H/Ypos., n = 7), predominantly presenting as mast cell leukemia (MCL; 6/7 patients), (b) MCL wi

The Debut Signal of Bone Metastasis and Stealthy Gastric Cancer Unmasked in a Young Male: A Case Report.

Gastric cancer is the fifth leading cause of cancer-related deaths in the world. The occurrence of bone metastases (BM) in gastric cancer without prior gastrointestinal (GI) symptoms is a rare phenomenon that has been sporadically documented in the existing literature. We report a case of a 27-year-old male presenting with chief complaints of severe backache for one month. After an upper gastrointestinal endoscopy and biopsy, the primary source of cancer was identified as a solitary gastric adenocarcinoma, supporting the diagnosis of bony metastases on the magnetic resonance imaging (MRI) of t

Post-kyphoplasty secondary vertebral compression fractures in Vietnamese patients: A single-center prospective cross-sectional study.

BACKGROUND: Despite its well-known effectiveness in vertebral compression fractures (VCFs), kyphoplasty could also bring the risk of developing subsequent VCFs post-augmentation, especially at adjacent vertebrae, which has been rarely reported in Asian countries. METHODS: In this cross-sectional study, we performed cement augmentation on 69 vertebrae in 65 patients at the Spine Surgery Department, Viet Duc University Hospital, from June 2019 to November 2020. Cement augmentation was performed on 69 vertebrae in 65 patients. They then were followed and assessed for subsequent VCFs every 3, 6,

Novel markers of early neutrophilic and monocytic engraftment after hematopoietic stem cell transplantation.

BackgroundNumerous studies tried to find new markers that after hematopoietic stem cell transplantation predict engraftment earlier than the conventional marker, absolute neutrophil count (ANC >500/µL). Early engraftment prediction can be achieved by a marker that reflects the release of neutrophils and monocytes into the leukopenic peripheral blood.MethodsWe analyzed blood cell parameters, including cell population data such as volume, conductivity, and light scatter in 77 patients who underwent HSCT (allogeneic, n=63; autologous, n=11) to detect possible markers.ResultsWe identified 2 early

Evolving Paradigms in Chronic Graft-Versus-Host Disease: From Global Immunosuppression to Precision Targeted and Cell-Based Therapies.

Allogeneic haematopoietic stem cell transplantation (allo-HSCT) is a well-established treatment for a range of medical conditions. However, the procedure carries with it a significant risk of chronic graft-versus-host disease (cGVHD), which can have a considerable impact on patients’ quality of life and clinical outcomes. In recent years, there has been a marked shift in treatment strategies for this condition, with greater emphasis being placed on novel targeted therapies and cell therapies that target specific pathways. This shift in approach signifies a more profound comprehension of the pa

Treating Protein Misfolding Diseases: Therapeutic Successes Against Systemic Amyloidoses.

Misfolding and extracellular deposition of proteins is the hallmark of a heterogeneous group of conditions collectively termed protein misfolding and deposition diseases or amyloidoses. These include both localized (e.g. Alzheimer's disease, prion diseases, type 2 diabetes mellitus) and systemic amyloidoses. Historically regarded as a group of maladies with limited, even inexistent, therapeutic options, some forms of systemic amyloidoses have recently witnessed a series of unparalleled therapeutic successes, positively impacting on their natural history and sometimes even on their incidence. I

Регулирование IFNG-AS1 и UCHL1-AS1 в периферальных кровяных клетках пациентов с множественным склерозом: IFNG-AS1 как потенциальный диагностический биомаркер.

Множественный склероз (MS) — нейродегенеративное и воспалительное заболевание, затрагивающее серую и белую материю в мозгу. Из-за весьма изменчивого представления MS чрезвычайно трудно сделать надежную долгосрочную диагностику, основанную исключительно на первоначальных клинических выводах. В ходе недавних исследований было продемонстрировано, что некодирующие РНК (lncRNA) в течение длительного времени играют определенную роль в качестве перспективных биомаркеров, которые могут предложить данные для прогнозирования возникновения и развития болезни. МЕТОДЫ: В состав группы по сбору проб крови б

Safety and efficacy of extended dosing intervals of denosumab in patients with solid cancers and bone metastases: a retrospective study.

AimMore than half of patients with breast, lung, or prostate cancer who have bone metastases have evidence of skeletal-related events (SREs). Denosumab is a fully human monoclonal antibody that binds to and neutralizes receptor activator of nuclear factor kappa-B ligand (RANKL) on osteoblasts and their precursors. The United States Food and Drug Administration (FDA)-approved dose of denosumab is 120 mg every 4 weeks; however, other schedules have been used in practice for patient convenience. Evidence for the safety and efficacy of alternative dosing intervals is lacking.Patient & methodsAdult

Cancer Metastases to Bone: Concepts, Mechanisms, and Interactions with Bone Osteoblasts.

The skeleton is a unique structure capable of providing support for the body. Bone resorption and deposition are controlled in a tightly regulated balance between osteoblasts and osteoclasts with no net bone gain or loss. However, under conditions of disease, the balance between bone resorption and deposition is upset. Osteoblasts play an important role in bone homeostasis by depositing new bone osteoid into resorption pits. It is becoming increasingly evident that osteoblasts additionally play key roles in cancer cell dissemination to bone and subsequent metastasis. Our laboratory has evidenc

Neurotropin alleviates rat osteocarcinoma pain via P2X3 receptor activation in the midbrain periaqueductal gray.

ObjectivesClinically effective analgesia treatment for patients afflicted with osteocarcinoma lessens the intensity of pain. The midbrain periaqueductal gray (PAG) plays a critical role in pain modulation, and activation of P2X3 receptors in this region mediates pain processing. Neurotropin is a small molecule drug used for analgesic treatment of a number of chronic pain conditions. The present study aims at determining whether P2X3 receptor activation in PAG is responsible for the analgesic effect of neurotropin in rats with osteocarcinoma pain.Materials and methodsThe tibia of female Sprague

Acute exercise mobilizes NKT-like cells with a cytotoxic transcriptomic profile but does not augment the potency of cytokine-induced killer (CIK) cells.

CD3+/CD56+ Natural killer (NK) cell-like T-cells (NKT-like cells) represent ex vivo into cytokine-induced killer (CIK) cells, however this therapeutic cell product has had mixed results against hematological malignancies in clinical trials. The aim of this study was to determine if NKT-like cells mobilized during acute cycling exercise could be used to generate more potent anti-tumor CIK cells from healthy donors. An acute exercise bout increased NKT-like cell numbers in blood 2-fold. Single cell RNA sequencing revealed that exercise mobilized NKT-like cells have an upregulation of genes and t

Real-Life Use of Ceftolozane/Tazobactam for the Treatment of Bloodstream Infection Due to Pseudomonas aeruginosa in Neutropenic Hematologic Patients: a Matched Control Study (ZENITH Study).

We sought to assess the characteristics and outcomes of neutropenic hematologic patients with Pseudomonas aeruginosa (PA) bloodstream infection (BSI) treated with ceftolozane-tazobactam (C/T). We conducted a multicenter, international, matched-cohort study of PA BSI episodes in neutropenic hematologic patients who received C/T. Controls were patients with PA BSI treated with other antibiotics. Risk factors for overall 7-day and 30-day case fatality rates were analyzed. We compared 44 cases with 88 controls. Overall, 91% of episodes were caused by multidrug-resistant (MDR) strains. An endogenou

Prospects and Advances in Adoptive Natural Killer Cell Therapy for Unmet Therapeutic Needs in Pediatric Bone Sarcomas.

Malignant bone tumors are aggressive tumors, with a high tendency to metastasize, that are observed most frequently in adolescents during rapid growth spurts. Pediatric patients with malignant bone sarcomas, Ewing sarcoma and osteosarcoma, who present with progressive disease have dire survival rates despite aggressive therapy. These therapies can have long-term effects on bone growth, such as decreased bone mineral density and reduced longitudinal growth. New therapeutic approaches are therefore urgently needed for targeting pediatric malignant bone tumors. Harnessing the power of the immune

Pharmacokinetics and outcome of high-dose melphalan followed by autologous stem cell transplantation in dialysis-dependent patients with multiple myeloma.

High-dose melphalan followed by autologous stem cell transplantation (ASCT) remains the standard of care for fit patients with multiple myeloma (MM). However, individuals who are dependent on hemodialysis are frequently excluded from ASCT. Recommendations on chemotherapy dosing and hemodialysis scheduling vary in literature and definite conclusions are impeded by the heterogeneity of cohorts. We aimed to evaluate the safety and efficacy of ASCT in patients with MM and end-stage renal disease and to examine the pharmacokinetics of melphalan on a fixed schedule of melphalan infusion and hemodial

Существенный потенциал борьбы с миломой вливания зеленого чая и его компонента дигидромиритина.

Множественная миелома (ММ) — фатальная гематологическая порча, характеризующаяся перерастанием моноклонных плазменных клеток. Хотя зеленый чай имеет хорошо задокументированные антивизорные свойства, его специфические последствия для MM по-прежнему плохо характеризуются. Цель этого исследования состояла в изучении антимиеломной активности вливаний четырех репрезентативных зеленых чая и выявлении их эффективных компонентов. Мы обнаружили, что апоптоз клеток MM был вызван зелеными чайными вливаниями в зависимости от концентрации, при этом вливание чая в Билуочун продемонстрировало самую мощную эф

RR Myelo POINT: A Retrospective Single-Center Study Assessing the Role of Radiotherapy in the Management of Multiple Myeloma and Possible Interactions with Concurrent Systemic Treatment.

Background and purpose: Although chemotherapy, biological agents, and radiotherapy (RT) are cornerstones of the treatment of multiple myeloma (MM), the literature regarding the possible interactions of concurrent systemic treatment (CST) and RT is limited, and the optimal RT dose is still unclear. Materials and methods: We retrospectively analyzed the records of patients who underwent RT for MM at our institution from 1 January 2005 to 30 June 2020. The data of 312 patients and 577 lesions (treated in 411 accesses) were retrieved. Results: Most of the treated lesions involved the vertebrae (60

Japanese POEMS syndrome with Thalidomide (J-POST) Trial: study protocol for a phase II/III multicentre, randomised, double-blind, placebo-controlled trial.

IntroductionPolyneuropathy, organomegaly, endocrinopathy, M-protein and skin changes (POEMS) syndrome is a fatal systemic disorder associated with plasma cell dyscrasia and the overproduction of the vascular endothelial growth factor (VEGF). Recently, the prognosis of POEMS was substantially improved by introduction of therapeutic intervention for myeloma. However, no randomised clinical trial has been performed because of the rarity and severity of the disease.Methods and analysisThe Japanese POEMS syndrome with Thalidomide (J-POST) Trial is a phase II/III multicentre, double-blinded, randomi
