Asparaginase-Associated Pancreatitis in Pediatric Patients with Acute Lymphoblastic Leukemia: Current Perspectives.

Asparaginase therapy is a vital agent in the treatment of acute lymphoblastic leukemia (ALL), with increasing evidence of its high importance in high-risk ALL populations. However, despite the clear clinical and biological benefits of asparaginase therapy, many patients experience toxicities. A well-known treatment-limiting toxicity is asparaginase-associated pancreatitis (AAP).

Venetoclax and Decitabine in Pediatric Refractory T-cell Lymphoblastic Lymphoma.

Background: Overall survival of adolescents with relapsed T-cell lymphoblastic lymphoma (T-LL) remains poor with limited options for salvage therapy. The BCL-2 inhibitor venetoclax combined with hypomethylating agents like decitabine, has shown favorable responses in elderly patients with acute myeloid leukemia.

Observation: We present the case of a 19-year-old adolescent with stage III relapsed and refractory T-LL who did not respond to 3 lines of salvage therapy.

Use of pegylated interferon in young patients with polycythemia vera and essential thrombocythemia.

Myeloproliferative neoplasms (MPN) are rare disorders in young patients, and because of this, standardized treatment recommendations are not available. Pediatric patients are more frequently treated with hydroxyurea than interferon, yet there are no data suggesting this is the best practice. Current treatment guidelines for adults suggest using interferon as upfront therapy in young patients.

Coincidental Expression of Classic Hodgkin Lymphoma and Neurofibromatosis Type I and Literature Review.

Neurofibromatosis Type 1 (NF1) is a genetic disorder with an incidence of 1 in 2600 to 3000 individuals. It is a clinical diagnosis characterized by café-au-lait macules, neurofibromas, and axillary and/or groin freckling. Because of genetic mutations in the NF1 gene affecting the Ras/mitogen-activated protein kinase pathway, there is also risk of associated soft tissue sarcomas and hematologic malignancies.
