Often diagnosed at advanced stages, gastric cancer prognosis remains poor. To address the critical need for accurate tumoral markers for gastric cancer diagnosis, we conducted a study to assess classical markers like CEA and CA-19-9 alongside the novel marker miR-106 . Our investigation revealed distinct dynamics of these markers compared to non-cancerous groups, although no disparities were observed across different disease stages. Univariable and multivariable logistic regression analyses demonstrated that elevated levels of miR-106, CEA and CA 19-9 were predictive of a positive histopathological exam, with the respective odds ratios of 12.032 (95% ","cbCaifFJvlJ2IZHf","https://ap.wps.com/l/cbCaifFJvlJ2IZHf","pdf",2205368,13,"English","# Introduction\n## Gastric cancer burden and need for early detection\n## Tumor and endoscopic markers for diagnosis\n## Rationale for investigating molecular biomarkers","[{\"question\":\"Which biomarkers were evaluated for gastric adenocarcinoma diagnosis and staging?\",\"answer\":\"The study assessed miR-106 as a novel marker and compared it with classical markers CEA and CA 19-9.\"},{\"question\":\"What did logistic regression show about marker levels?\",\"answer\":\"Elevated levels of miR-106, CEA, and CA 19-9 were predictive of a positive histopathological exam, with reported odds ratios for each marker.\"},{\"question\":\"Which marker performed best in ROC analysis for diagnosis?\",\"answer\":\"CA 19-9 was identified as the optimal predictor for gastric adenocarcinoma diagnosis when accounting for age and gender, with an AUC of 0.936 (p \\u003c 0.001).\"}]","In Pursuit of Novel Markers - Unraveling the Potential of miR-106, CEA and CA 19-9 in Gastric Adenocarcinoma Diagnosis and Staging | PDF",1789979647,33]
