An 80-year-old man underwent colonic interposition between the upper esophagus and stomach after surgery for an early esophageal squamous cell carcinoma in 1994. He received a surveillance endoscopy, and a laterally-spreading tumor of granular type, approximately 20 mm in size, was identified in the colonic interposition. An endoscopic biopsy revealed moderately differentiated adenocarcinoma histologically, however, we diagnosed the lesion as an intramucosal carcinoma based on the endoscopic findings. The lesion was safely and completely removed en bloc by ESD using a bipolar knife. Histologically, the lesion was an intramucosal moderately differentiated adenocarcinoma in a tubular adenoma.展开更多
为探究血清PIVKA-Ⅱ与AFP检测在原发性肝细胞癌诊断中的优劣性,对237例患者的血清PIVKA-Ⅱ与AFP进行检测,其中乙肝病毒相关性原发性肝细胞癌(hepatocellular carcinoma, HCC)患者115例、乙肝携带者(asymptomatic carrier, As C) 55例、...为探究血清PIVKA-Ⅱ与AFP检测在原发性肝细胞癌诊断中的优劣性,对237例患者的血清PIVKA-Ⅱ与AFP进行检测,其中乙肝病毒相关性原发性肝细胞癌(hepatocellular carcinoma, HCC)患者115例、乙肝携带者(asymptomatic carrier, As C) 55例、乙肝病毒相关肝硬化(liver cirrhosis, LC)患者47例、非肝癌肿瘤患者20例。检测结果显示:肝癌组PIVKA-Ⅱ的中位表达量高于非肝癌组(包括As C组、LC组、非肝癌肿瘤组), P均小于0.05;使用AFP、PIVKA-Ⅱ和AFP+PIVKA-Ⅱ诊断肝癌的灵敏度分别为67.8%、81.7%和90.4%,对应的ROC曲线下面积为0.881、0.945和0.962, PIVKA-Ⅱ检测肝癌的cut-off值为32 m AU/m L。已有研究报道以40 m AU/m L为PIVKA-Ⅱ的cut-off值,本研究根据PIVKA-Ⅱ是否≥40 m AU/m L将HCC组分为PIVKA-Ⅱ≥40组、PIVKA-Ⅱ<40组,对两组患者的性别、年龄、病毒载量、肿瘤分期、癌结节数目、肿块直径和是否抗病毒治疗进行比较,采用logistic回归分析两组患者的差异性指标,结果显示病毒载量[OR=1.150, 95%CI (1.022, 1.295), P=0.02]为PIVKA-Ⅱ检测肝癌的独立影响因素。相关分析表明PIVKA-Ⅱ与肝癌肿块直径呈正相关。此外, AFP、PIVKA-Ⅱ的cut-off值分组结果表明, PIVKA-Ⅱ≥32且AFP<20组的肝癌肿块直径大于PIVKA-Ⅱ<32且AFP≥20组(P=0.035)。因此, PIVKA-Ⅱ是优于AFP筛查肝细胞癌的血清学肿瘤标志物,其表达量与肿瘤肿块直径呈正相关。展开更多
