[The Research Progress in the Diagnosis and Treatment of Primary Intestinal Diffuse Large B-cell Lymphoma--Review].

Primary intestinal diffuse large B-cell lymphoma (PI-DLBCL) is clinically rare, but in recent years, with the gradual maturity of pathology and molecular biology technology, its incidence rate and diagnosis rate have also increased. Due to the lack of specificity of the clinical symptoms of PI-DLBCL, it is easy to misdiagnose and miss the diagnosis, and there is no consensus on the best treatment of PI-DLBCL in clinical practice. Therefore, by retrieving the latest literature at home and abroad, this review systematically discusses the pathogenesis, clinical manifestations, diagnostic criteria, treatment and prognosis of PI-DLBCL, in order to improve the understanding of rare PI-DLBCL in hematology and oncology, and provide reference for basic research and clinical diagnosis and treatment of PI-DLBCL.

Sintilimab (anti-PD-1 antibody) plus chidamide (histone deacetylase inhibitor) in relapsed or refractory extranodal natural killer T-cell lymphoma (SCENT): a phase Ib/II study.

Anti-PD-1 antibodies are a favorable treatment for relapsed or refractory extranodal natural killer T cell lymphoma (RR-ENKTL), however, the complete response (CR) rate and the duration of response (DOR) need to be improved. This phase 1b/2 study investigated the safety and efficacy of sintilimab, a fully human anti-PD-1 antibody, plus chidamide, an oral subtype-selective histone deacetylase inhibitor in 38 patients with RR-ENKTL. Expected objective response rate (ORR) of combination treatment was 80%.

It is urgent to search for safe and effective therapies to address the CRC crisis. The siRNA-based RNA interference targeted silencing of PD-L1 has extensive potential in CRC treatment but is limited by the lack of efficient delivery vectors.

Targeting as a Therapeutic Approach for Angioimmunoblastic T Cell Lymphoma.

Angioimmunoblastic T-cell lymphoma (AITL), a type of malignant lymphoma with unique genomic aberrations, significant clinicopathological features, and poor prognosis, is characterized by immune system dysregulation. Recent sequencing studies have identified recurrent mutations and interactions in tet methylcytosine dioxygenase 2 (), ras homology family member A (), DNA methyltransferase 3 alpha (), and mitochondrial isocitrate dehydrogenase II (). Notably, since B-cell lymphomas are frequently observed along with AITL, this review first summarizes its controversial mechanisms based on traditional and recent views.

Here, we aimed to explore the clinical significance and biological involvement of COL6A1 in the OS cell migration and invasion.

A proposal for a prognostic index for non-nasal type natural killer/T cell lymphoma after asparaginase-based treatment.

In the era of asparaginase-based therapy for extranodal natural killer/T cell lymphoma (ENKTL), the clinical outcomes of ENKTL have notably improved. However, as a rare subtype of ENKTL, the therapeutic effect and prognostic factors of non-nasal type ENKTL remain unclear. Thus, we performed this study to analyze the clinical characteristics and to establish a prognostic model specifically for the non-nasal disease.

Detection of human papillomavirus distinguishes second primary tumors from lung metastases in patients with squamous cell carcinoma of the cervix.

Background: In patients with squamous cell carcinoma of the cervix (SCCC), a squamous cell carcinoma (SqCC) in the lung represents either a second primary tumor or metastasis. This distinction between second primary tumors and lung metastases in patients with SCCC significantly influences patient prognosis and therapy. Here, we aimed to differentiate second primary tumors from lung metastases in patients with SCCC by exploring the HPV status in SqCCs involving the lung within a large cohort.
