Esophageal squamous cell carcinoma (ESCC) and esophageal adenocarcinoma (EAC) are the two major types of ECs, with EAC having one of the worst prognoses in oncology. Limited screening techniques and a lack of molecular analysis of diseased tissues have led to late-stage presentation and very low survival durations. The five-year survival rate of EC is less than 20% . Thus, early diagnosis of EC may prolong survival and improve clinical outcomes. Cellular and molecular biomarkers are used for diagnosis. At present, esophageal biopsy during upper endoscopy and histopathological analysis is the standard screening modality for both ESCC and EAC. However, this is an invasive method that fails to yield a molecular profile of the diseased compartment. To decrease the invasiveness of the procedures for diagnosis, researchers are proposing non-invasive biomarkers for early diagnosis and point-of-care screening options. Liquid biopsy involves the collection of body fluids (blood, urine, and saliva) non-invasively or with minimal invasiveness. In this review, we have critically discussed various biomarkers and specimen retrieval techniques for ESCC and EAC.  \nKeywords: esophageal carcinoma; esophageal adenocarcinoma; biomarkers; blood; urine; saliva  \n1. Introduction  \nIts poor prognosis and high mortality rate make esophageal cancer (EC) one of the deadliest cancers worldwide. EC is the eighth most common cancer worldwide (the seventh most common cancer in men and the thirteenth most common cancer in women) and the sixth leading cause of cancer-related deaths. The two most common histological types of EC, namely esophageal squamous cell carcinoma (ESCC) and esophageal adenocarcinoma (EAC), account for more than 90% of ECs. The five-year survival rate of EC is less than 20%[1–4] . A recent retrospective study reporting 23,804 EAC cases and 13,919 ESCC cases suggests an increasing incidence of EAC and a decreasing incidence of ESCC in the United States [3] . ESCC is characterized by the conversion of the normal squamous esophageal epithelium to ESCC via basal cell hyperplasia, dysplasia, and invasiveness. ESCC may involve any part of the esophagus (20% upper, 50% middle, and 30% lower esophagus) . Alcohol and tobacco consumption, the most common risk factors, cause cellular DNA damage and contribute to ESCC. EAC occurring in the distal esophagus occurs due to a cascade progressing from gastroesophageal reflux disease (GERD) to Barrett's esophagus (BE), followed by EAC with columnar metaplasia playing a cr","cbCaiczdULv6I4QU","https://ap.wps.com/l/cbCaiczdULv6I4QU","pdf",1099361,18,"English","# Abstract\n# Introduction\n## Major EC types and epidemiology\n## Risk factors and disease pathogenesis\n## Early detection strategies and screening challenges\n## Treatment approaches for early and advanced EC","[{\"question\":\"Why are biomarkers important for esophageal cancer care?\",\"answer\":\"Biomarkers can support early diagnosis and improve clinical outcomes by enabling molecular profiling rather than relying solely on invasive histopathological assessment.\"},{\"question\":\"What are the two major histological types of esophageal cancer discussed?\",\"answer\":\"The review focuses on esophageal squamous cell carcinoma (ESCC) and esophageal adenocarcinoma (EAC), which together account for more than 90% of esophageal cancers.\"},{\"question\":\"What non-invasive screening approach is highlighted as a promising option?\",\"answer\":\"Liquid biopsy is emphasized, using body fluids such as blood, urine, and saliva to enable non-invasive or minimally invasive biomarker collection.\"}]","Biomarkers for Early Detection, Prognosis, and Therapeutics of Esophageal Cancers | PDF",1790226311,45]
