随着RIA技术的发展,CEA RIA已广泛应用于临床.本文仅就组织浸泡液CEA RIA进行探讨.材料和方法一、正常组织组:标本来源于非肿瘤疾患手术切除的组织块.二、良性肿瘤组织组:标本来自子宫肌瘤手术切除的肿瘤组织.三、恶性肺瘤组织组:标本来源于恶性肿瘤患者手术切除的肿瘤组织.正常组织组取材无特异性;良性肿瘤组以瘤体取材;恶性肿瘤组标本取材分为肿瘤组织组和肿瘤周围组织组两部分.肿瘤组织组从瘤体取材,肿瘤周围组织组分别从距离肿瘤边1.5cm和3.0Cm处取材. With the development of RIA technology, CEA RIA has been widely used in clinical.This article only on the tissue soaking CEA RIA to explore.Materials and methods First, the normal tissue group: specimens from non-tumor disease surgical resection of the tissue block. Second, the benign Tumor Tissue Group: Specimens were obtained from resected tumor tissue of uterine fibroids.Three, Malignant tumor group: Specimens were derived from the surgically resected tumor tissue of patients with malignant tumor.The specimens of normal tissue were nonspecific; The specimens of malignant tumor were divided into two groups: tumor tissue group and tumor surrounding tissue group.The tumor tissue group was taken from the tumor and the tumor surrounding tissue group was taken from 1.5cm and 3.0cm away from the tumor.
