A previously healthy 12-year-old boy presented with acute onset of proptosis of his left eye. CT scan demonstrated a mass involving the left orbit, left maxillary sinus, and left ethmoid sinus with extension through the cribriform plate into the anterior cranial fossa. Incisional biopsy of the mass revealed a precursor B-cell lymphoblastic lymphoma. Precursor B-cell lymphoblastic lymphoma is a rare type of non-Hodgkin's lymphoma seen exclusively in children and young adults. This is the first reported case of precursor B-cell lymphoblastic lymphoma presenting in the orbit. Treatment is primarily by systemic chemotherapy and is potentially curative. The principal role of the ophthalmologist is in diagnosis and monitoring of such patients. The clinical features and multidisciplinary diagnosis and management of childhood non-Hodgkin's lymphomas are reviewed.

B-cell acute lymphoblastic leukemia (B-ALL) is the most common form of cancer diagnosed in children. While the majority of patients survive with conventional treatment, chemotherapeutic agents have adverse effects and the potential for relapse persists even after full recovery. Given their pivotal function in anti-cancer immunity, there has been a surge in research exploring the potential of natural killer (NK) cells in immunotherapy, which has emerged as a promising avenue for treating leukemia.

Recent studies have demonstrated the association between constitutional ring chromosome 21 (r(21)c) and the development of B-cell acute lymphoblastic leukemia (B-ALL) with intrachromosomal amplification of chromosome 21 (iAMP21). iAMP21 acts as a driver which is often accompanied by secondary alterations that influence disease progression. Here, we report an atypical case of iAMP21 B-ALL with a unique molecular profile in the context of r(21)c.

IKZF1 deletions (ΔIKZF1) are common in precursor B-cell acute lymphoblastic leukemia (B-ALL) and are assumed to have a prognostic impact. We aimed to determine the prognostic implications of ΔIKZF1 and CRLF2 overexpression in pediatric B-ALL. Furthermore, we sought to compare the multiplex polymerase chain reaction (PCR) assay with standard multiplex ligand-dependent probe amplification (MLPA) methods to ascertain IKZF1 status in a clinical context.

Various therapeutic strategies have been developed to treat Pancreatic Cancer (PaCa). Unfortunately, most efforts have proved unfruitful, as the poor prognosis observed in this disease has only attained little improvement in the past 40 years. Recently, deeper understanding of the immune system and its interaction with malignant tumors have allowed significant advances in immunotherapy.

Objective: To analyze the expression of B-cell development-related genes in acute B lymphoblastic leukemia (B-ALL), and to explore the relationship between B-cell development-related genes and the prognosis of B-ALL patients.
Methods: The GEO and TARGET databases were integrated to analyze the differential expression of B-cell development-related genes between the healthy persons and B-ALL patients and their differential expression in the B-ALL relapse and non-relapse groups. Cox single factor regression and Lasso regression were used to constructe a B-ALL specific prognosis model of B-cell development-related genes.
