LP is an extremely heterogeneous tumor caused by mutations in oncogenic and tumor suppressive genes, as well as molecular pathways, along with mutations in stromal cells and proteins related to tight junctions. Elucidating the molecular background of tumorigenesis and clarifying the correlation between cancerous cells and stromal cells are crucial steps toward discovering novel diagnostic methods, biomarkers and therapeutic targets/agents. Surgery plays a pivotal role in LP management, serving both as a palliative and curative procedure. In this comprehensive review, we aim to present all recent data on the molecular background of LP and the novel approaches to its management.  \nKeywords: Linitis Plastica; Borrmann type IV; oncogenes in LP; biomarkers; targeting agents; surgery  \n1. Introduction  \nGastric cancer (GC) ranks as the fifth most common malignancy worldwide, with approximately 1.1 million new cases annually. It stands out as having one of the highest mortality rates with the third most deaths [1–4] . Linitis Plastica (LP), a subtype of gastric cancer, constitutes 10% of all GC cases [2,5,6] . First observed in the 16th and 17th centuries, it was formally described in 1859 by William Brinton [7] . Macroscopically, LP is characterized by the thickening of the gastric folds due to accumulation of fibrous tissue, often referred to as the “Leather-bottle stomach” [3,5,7,8] . The term “Linitis” derives from its“linen-like” macroscopical image. LP originates from the fundic gland cells and infiltrates the entire stomach with a desmoplastic growth pattern, unlike the development of a solid tumor. Tumor cells are dispersed within the thickened fibrous tissue, extending into the submucosal and serous layer [5,7,9–11] . In 91.1% of cases, LP presents as a poorly differentiated adenocarcinoma, and in 77.7% of cases, it is often histologically linked with signet ring cells [8] . However, diagnosing LP is a complex and challenging endeavor, due to the i","cbCaiisGa4QdTSbL","https://ap.wps.com/l/cbCaiisGa4QdTSbL","pdf",279378,12,"English","# Introduction\n# Molecular background of Linitis Plastica\n# Diagnostic challenges and biomarkers\n# Targeted/therapeutic approaches\n# Role of surgery in management","[{\"question\":\"What defines the clinical and pathological development pattern of Linitis Plastica?\",\"answer\":\"Linitis Plastica is characterized by infiltration of the gastric wall, thickening of the gastric folds, and a “leather bottle appearance,” reflecting a desmoplastic growth pattern rather than a solid tumor mass.\"},{\"question\":\"Why is LP considered highly heterogeneous at the molecular level?\",\"answer\":\"LP heterogeneity stems from mutations in oncogenic and tumor suppressive genes and multiple molecular pathways, together with mutations in stromal cells and proteins associated with tight junctions.\"},{\"question\":\"How does surgery contribute to LP management?\",\"answer\":\"Surgery plays a pivotal role, serving as both a palliative and a curative procedure depending on clinical context and resectability.\"}]","The Genomic Signatures of Linitis Plastica Signal the Entrance into a New Era: Novel Approaches for Diagnosis and Treatment | PDF",1790224155]
