Palliative Care in Pediatric Oncology and Hematopoietic Stem Cell Transplantation.

PURPOSE OF REVIEW: To summarize pediatric palliative care (PPC) research from 2016 to 2021 as it intersects with pediatric oncology and hematopoietic stem cell transplantation (HSCT). RECENT FINDINGS: Children and adolescents with cancer who receive PPC have improved quality of life (QOL), symptom burden, advance care planning discussions, rates of hospice enrollment, home deaths, and receive less intensive therapy at the end-of-life (EOL). Parents report improved QOL and preparation for EOL. Though barriers to PPC utilization exist, new clinical models, oncology team education, and growing family awareness are leading to culture change. PPC within pediatric oncology is considered a standard of care. Families are accepting of PPC, as most wish for their children to live as well as possible for as long as possible. Although PPC remains underutilized, PPC should work collaboratively with pediatric oncology and HSCT teams to improve QOL and EOL outcomes of patients with cancer and their families.

Core-Fucosylated Tetra-Antennary N-Glycan Containing A Single N-Acetyllactosamine Branch Is Associated with Poor Survival Outcome in Breast Cancer.

(1) Glycoproteins account for ~80% of proteins located at the cell surface and in the extracellular matrix. A growing body of evidence indicates that α-L-fucose protein modifications contribute to breast cancer progression and metastatic disease. (2) Using a combination of techniques, including matrix-assisted laser desorption/ionization imaging mass spectrometry (MALDI-IMS) based in cell and on tissue imaging and glycan sequencing using exoglycosidase analysis coupled to hydrophilic interaction ultra-high performance liquid chromatography (HILIC UPLC), we establish that a core-fucosylated tetra-antennary glycan containing a single N-acetyllactosamine (F(6)A4G4Lac1) is associated with poor clinical outcomes in breast cancer, including lymph node metastasis, recurrent disease, and reduced survival. (3) This study is the first to identify a single N-glycan, F(6)A4G4Lac1, as having a correlation with poor clinical outcomes in breast cancer.
