Very early remission and increased apoptosis with the use of Pentoxifylline in children with acute lymphoblastic leukemia.

Introduction: Despite the improvement in survival in acute lymphoblastic leukemia (ALL), there are still cases with evasion of chemotherapy-induced apoptosis. The IKK/NF-κB signaling pathway contributes to antiapoptotic gene expression. Pentoxifylline (PTX) inhibits IkB phosphorylation, blocking NF-κB and antiapoptotic activity.

Impact of treatment and clinical characteristics on the survival of children with medulloblastoma in Mexico.

Introduction: Data on medulloblastoma outcomes and experiences in low- and middle-income countries, especially in Latin America, is limited. This study examines challenges in Mexico's healthcare system, focusing on assessing outcomes for children with medulloblastoma in a tertiary care setting.

Methods: A retrospective analysis was conducted, involving 284 patients treated at 21 pediatric oncology centers in Mexico.
