T-cell/histiocyte-rich large B-cell lymphoma (THRLBCL) is a distinct subtype of diffuse large B-cell lymphoma (DLBCL) under-recognized in the pediatric population. A meticulous workup is necessary to avoid a misdiagnosis of nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL) or classical Hodgkin lymphoma (HL). A strong degree of suspicion and an emphasis on immunohistochemical staining are required to reach the diagnosis. Few children with advanced stage disease have been described to date. We report two pediatric patients with high stage THRLBCL and highlight their clinical and pathological features.

: Retrospective studies are often criticized for their susceptibility to case selection bias compared to prospective studies, which include all patients consecutively and are thus less prone to such limitations. However, the larger sample sizes typical of retrospective studies can sometimes offset this drawback. On behalf of the Fondazione Italiana Linfomi (FIL), a substantial retrospective study involving 946 patients was conducted to examine the use of non-pegylated liposomal anthracycline (Myocet).

Lung malignancies, including cancerous lymphangitis and lymphomas, can mimic interstitial lung diseases like cryptogenic organizing pneumonia (COP) on imaging, leading to diagnostic delays. We aimed to identify potential biomarkers to distinguish between these conditions. We analyzed bronchoalveolar lavage fluid from 8 patients (4 COP, mean age 59.

T-cell redirecting therapies, which include chimeric antigen receptor T-cells (CAR-Ts) and bispecific antibodies (BSAs), have revolutionized the treatment of relapsed\refractory large B-cell lymphoma (LBCL). Expanding clinical experience with these advanced therapies shows the potential for the optimization of their use with combination or consolidation strategies, which necessitates the prognostic stratification of patients. While traditional clinical prognostic factors identified in the era of chemotherapy are characterized by limited value, the tumor microenvironment (TME) is becoming a new prognostic cluster.

Diabetes is a chronic metabolic disorder whose prevalence increases every year, affecting more than 530 million adults worldwide. Type 1 (T1D) and type 2 diabetes (T2D), the most common forms of diabetes, are characterized by the loss of functional pancreatic β-cells, mostly due to apoptosis. B-cell leukemia/lymphoma 2 (Bcl-2) and B-cell lymphoma-extra large (Bcl-xL), two anti-apoptotic proteins belonging to the Bcl-2 family, are crucial for regulating the intrinsic pathway of apoptosis.

Lung cancer is a leading global cause of mortality, with non-small cell lung cancer (NSCLC) accounting for a significant portion of cases. Immune checkpoint inhibitors (ICIs) have transformed NSCLC treatment; however, many patients remain unresponsive. ICI resistance in NSCLC and its association with cellular plasticity, epithelial-mesenchymal transition (EMT), enhanced adaptability, invasiveness, and resistance is largely influenced by epigenetic changes, signaling pathways, tumor microenvironment, and associated immune cells, fibroblasts, and cytokines.
