All breast cancer subtypes are accompanied by peculiar and substantial changes in sphingolipid metabolism. Alterations in sphingolipid metabolite levels, such as ceramides, dihydroceramide, sphingosine, sphingosine-1-phosphate, and sphingomyelin, as well as in their biosynthetic and catabolic enzymatic pathways, have emerged as molecular mechanisms by which breast cancer cells grow, respond to or escape therapeutic interventions and could take on diagnostic and prognostic value. In this review, we summarize the current landscape around two main themes: 1 . sphingolipid metabolites, enzymes and transport proteins that have been found dysregulated in human breast cancer cells and/or tissues; 2 . sphingolipid-driven mechanisms that allow breast cancer cells to respond to or evade therapies. Having a complete picture of the impact of the sphingolipid metabolism in the development and progression of breast cancer may provide an effective means to improve and personalize treatments and reduce associated drug resistance.  \nKeywords: breast cancer; sphingolipids; lipids; metabolism; ceramide; sphingomyelin; drug sensitivity; drug resistance; biomarkers  \n1. Introduction  \nBreast cancer (BC) continues to be the second leading cause of cancer death among women worldwide, despite, over the last 30 years, BC death rates dropping due to increased awareness of the disease, advances in diagnosis, and more effective therapeutic interventions [1] . Major advances regarding diagnosis, prognosis, and treatment of BC, including in surgery, chemotherapy, immunotherapy, and radiotherapy, are due to multiple and interdisciplinary approaches which, over time, have led to a progressive improvement in the classification of BCs [2–5] .  \nCurrently, the classification system of BCs considered most useful and effective, and therefore increasingly used by clinicians for the choice of therapeutic intervention, is based on the presence, or absence, of specific biomarkers in tumor specimens [3,6] . In particular, according to estrogen receptor (ER) and progesterone receptor (PR) expression levels and human epidermal growth factor receptor 2 (ErbB2, also known as HER2) status, BCs are basically divided into four main subtypes [3,6] . Luminal A and Luminal B BCs are both positive for hormone receptors (ER+ and PR+) but differ in the HER2 status (Luminal A is HER2-, whereas Luminal B is HER2+) and in the expression levels of the cell diffe","cbCaieBkTI1VpHah","https://ap.wps.com/l/cbCaieBkTI1VpHah","pdf",1772586,25,"English","# Introduction\n## Breast cancer subtypes and biomarker-based classification\n## Therapeutic responses and limits due to resistance\n# Abstract\n## Role of sphingolipid metabolism in progression and drug response\n# Keywords\n## Core topics: sphingolipids, metabolism, ceramide and biomarkers","[{\"question\":\"What treatments are discussed for managing breast cancer, and what determines their effectiveness?\",\"answer\":\"Management combines surgery, radiation therapy, chemotherapy, and immunotherapy.
