Low-grade B cell non-Hodgkin lymphomas typically arise from the marginal zone of the secondary lymphatic follicles. Their intracranial expression is very rare, most frequently affecting the dura mater and the choroid plexus glomi in the lateral ventricles. Their initial evaluation requires the exclusion of more common extra-axial lesions, such as meningiomas, dural metastasis, granulomatous lesions or secondary lymphoproliferative dural extension from body lymphomas. Whenever a ventricular lesion is present, the patient's age and lesion location help narrow the differential diagnosis. Dural-based lymphomas and ventricular/choroid plexus lymphomas are slow-growing lesions with imaging features similar to meningiomas, which is typically their main differential consideration. Diffusion-weighted images frequently show restricted diffusion behaviour on lymphomas, helping to differentiate them from the typical meningiomas.

High-grade-B-cell lymphoma (HGBL) with MYC and BCL2 and/or BCL6 rearrangements (double hit [HGBL-DH] or triple hit [HGBL-TH]), or not otherwise specified (HGBL-NOS), are considered to be more aggressive diseases among large B-cell lymphomas (LBCL). CD19-targeting Chimeric Antigen Receptor (CAR) T-cells have changed the prognosis of chemoresistant LBCL. Clinical and pathological data of patients treated for relapsed/refractory LBCL or HGBL in third line or more, all characterized by FISH, were collected from the French DESCAR-T registry.

Hepatosplenic T-cell lymphoma (HSTCL) is an aggressive mature T-cell lymphoma characterized by significant hepatosplenomegaly, bone marrow involvement, and minimal or no lymphadenopathy. Primarily affecting young adults, it is exceptionally rare in children and adolescents. This makes diagnosis and treatment particularly challenging for pathologists and pediatric oncologists.

However, ATO administration requires daily infusions over several months, representing an onerous burden for hospitals and patients. We evaluated the bioavailability of a novel encapsulated oral ATO formulation in APL patients in first complete remission during standard-of-care consolidation.

Objective: To apply the Toronto Childhood Cancer Staging Guidelines (TG) and Estimate the Observed Survival Probabilities for Pediatric Patients with Leukemia and Lymphoma.
Methods: Staging at diagnosis was conducted according to tier 2 of the TG. The study cohort included patients aged 0 -19 years from the Population-Based Cancer Registry (PBCR) of Mato Grosso, diagnosed with leukemia and lymphoma between 2008 and 2017, with follow-up until December 31, 2022.

Background: Acute Lymphoblastic Leukemia (ALL) is the most common type of leukemia among children. There are several types of drugs that are common in treating and controlling leukemia, including 6-M. Moreover, the anti-cancer effects of the Thiosemicarbazone-Ni complex were surveyed as well as 6-MP.
