1、-2007届临床七年制硕士研究生毕业论文2、3年生存率分别为87.9%、84.8%和81.2%。MALT淋巴瘤和DLBCML的生存率高于DLBCL,IE期病例的生存率高于II1E期以上者,术前LDH正常者生存率较LDH升高者高(p<0.05)。通过本研究发现,PMGL的发病年龄偏高,以老年为主。症状缺乏特异性。影像学检查对PMGL的确诊价值低。PMGL内镜下表现易与胃癌混淆,具有多形性、多灶性和弥漫性特点。胃窦部最常受累。胃镜活检病理检查对术前诊断PMGL至关重要,但确诊率不高。多点式、“挖洞”式活检,
2、结合免疫组化等相关辅助诊断技术可提高术前确诊率。各病理类型PMGL的生物学行为不同,肿瘤形态、浸润深度、临床分期和预后也不同。治疗方案应根据不同的病理类型、临床分期及Hp感染与否而制定。疾病预后主要与病理类型和临床分期有关,本研究提示术前LDH升高者预后不佳。关键词:原发性胃恶性淋巴瘤,临床表现,病理诊断,内镜检查---2007届临床七年制硕士研究生毕业论文THESTUDYOFCLINICALANDPATHOLOGICALFEATURESOFPRIMARYMALIGNANTGASTRICLYMPHOMA
