Solid tumors contain a mixture of malignant cells and non-malignant infiltrating cells that often create a chronic inflammatory and immunosuppressive microenvironment that restricts immunotherapeutic approaches. Although childhood and adult cancers share some similarities related to microenvironmental changes, pediatric cancers are unique, and adult cancer practices may not be wholly applicable to our pediatric patients. This review highlights the differences in tumorigenesis, viral infection, and immunologic response between children and adults that need to be considered when trying to apply experiences from experimental therapies in adult cancer patients to pediatric cancers.

Malignant peripheral nerve sheath tumors (MPNSTs) are aggressive sarcomas and the primary cause of mortality in patients with neurofibromatosis type 1 (NF1). These malignancies develop within preexisting benign lesions called plexiform neurofibromas (PNs). PNs are solely driven by biallelic loss eliciting RAS pathway activation, and they respond favorably to MEK inhibitor therapy.

Purpose: Lumbar puncture is a frequently performed procedure for patients undergoing treatment for acute lymphoblastic leukemia. This brief procedure is frequently performed with sedation in young patients but with only local anesthesia in adults. Adolescent and young adult patients may be cared for by physicians with different training backgrounds and sedation preferences, making the utilization of sedation for lumbar punctures variable among providers.

Childhood cancers, with leukemia at the forefront, comprise 97% acute leukemia and 3% chronic leukemia, with 75% of acute leukemias being of lymphoblastic origin. Over the past 50 years, survival rates have witnessed a remarkable increase, progressing from around 10% to achieving cure rates exceeding 90% in certain childhood ALL subgroups with the advent of combined therapies. Between 1999 and 2018, a total of 123 patients diagnosed with B-ALL were initially identified, but after applying exclusion criteria, 105 patients were included in the evaluation, who were treated with COG protocols at our center.
