Gastroesophageal junction adenocarcinoma (GEJA) is a malignant tumor located at the junction of the esophagus and stomach, the incidence of which is increasing year by year, while screening for early biomarkers is limited. Tandem mass tagging (TMT) coupled with liquid chromatography–tandem mass spectrometry (LC/MS/MS) has been used to screen for differential proteins in various cancers.

串联质谱联用液相色谱-串联质谱技术检测胃食管结合部腺癌蛋白标志物

胃食管交界处腺癌（GEJA）是一种位于食管和胃交界处的恶性肿瘤，发病率逐年上升，而早期生物标志物的筛查有限。串联质谱标记 (TMT) 与液相色谱-串联质谱 (LC/MS/MS) 相结合已被用于筛选各种癌症中的差异蛋白。
