A life-threatening bleeding prediction model for immune thrombocytopenia based on personalized machine learning: a nationwide prospective cohort study.

Rare but critical bleeding events in primary immune thrombocytopenia (ITP) present life-threatening complications in patients with ITP, which severely affect their prognosis, quality of life, and treatment decisions. Although several studies have investigated the risk factors related to critical bleeding in ITP, large sample size data, consistent definitions, large-scale multicenter findings, and prediction models for critical bleeding events in patients with ITP are unavailable. For the first time, in this study, we applied the newly proposed critical ITP bleeding criteria by the International Society on Thrombosis and Hemostasis for large sample size data and developed the first machine learning (ML)-based online application for predict critical ITP bleeding.

Orelabrutinib for the treatment of relapsed or refractory MCL: a phase 1/2, open-label, multicenter, single-arm study.

Relapsed or refractory (r/r) mantle cell lymphoma (MCL) is an aggressive B-cell malignancy with a poor prognosis. Bruton tyrosine kinase (BTK) is a mediator of B-cell receptor signaling and is associated with the development of B-cell lymphomas.

[Research Advance of Venetoclax in Hematological Tumors--Review].

Venetoclax is a selective inhibitor of the anti-apoptotic protein B-cell lymphoma 2（BCL-2）and has great potential in treating a variety of hematological tumors. In recent years, domestic and foreign scholars have tried to use venetoclax singal or in combination with some drugs to treat the patients with hematological tumors, including elderly acute myeloid leukemia（AML）patients un suitable for intensive chemotherapy, relapsed or refractory chronic lymphocytic leukemia（CLL）, Non-Hodgkin's lymphoma（NHL）and multiple myeloma（MM）patients, these studies have achieved good results．At the same time，some scholars found that the secondary drug-resistance occurred in some patients who continuous treated with Venetoclax, and explored the Venetoclax-resistant mechanism. In this review, the research advance of Venetoclax in hematological tumors and the mechanisms of drug resistance are summarized and discussed briefly.

Here we conducted a phase 2, multicenter, randomized, controlled trial, comparing the efficacy and safety of CEOP/IVE/GDP alternating regimen with CEOP in newly diagnosed PTCL.

Methods: PTCL patients, except for anaplastic large cell lymphoma-anaplastic lymphoma kinase positive, were 1:1 randomly assigned to receive CEOP/IVE/GDP (CEOP, cyclophosphamide 750 mg/m, epirubicin 70 mg/m, vincristine 1.

Characterization of CD103 CD8 tissue-resident T cells in esophageal squamous cell carcinoma: may be tumor reactive and resurrected by anti-PD-1 blockade.

Though therapy that promotes anti-tumor response about CD8 tumor-infiltrating lymphocytes (TILs) has shown great potential, clinical responses to CD8 TILs immunotherapy vary considerably, largely because of different subpopulation of CD8 TILs exhibiting different biological characters. To define the relationship between subpopulation of CD8 TILs and the outcome of antitumor reaction, the phenotype and function of CD103 CD8 TILs in esophageal squamous cell carcinoma (ESCC) were investigated. CD103 CD8 TILs were presented in ESCC, which displayed phenotype of tissue-resident memory T cells and exhibited high expression of immune checkpoints (PD-1, TIM-3).
