Methods: 42 archival cases of nasopharyngeal were collected, each case contained the normal tissue and 3 cancer nests or region, 4 μ m, 8 μ m consecutive tissue section were cut on each case. 方法:收集鼻咽癌归档病例42例,每个病例包括正常鼻咽上皮组织和3个癌巢或肿瘤区域,制成4μm、8μm连续组织切片各一张。
In oral squamous cell carcinoma, strong expression was found in superficial layer, while allotropic expression in cytoplasm was found in cancer cell nests infiltrated into mesenchyme, accompany with weaken or loss of staining. 在口腔鳞状细胞癌中,表面膜为强阳性,侵入到间质深层的癌细胞团块出现胞浆移位,同时表达强度明显下降或丢失。
No positive cells were found around the cancer cell nests of invasive carcinomas. 在浸润性癌中,癌巢周围不见阳性细胞。
Some sporadic necrosis cancer nests have no cell structures. 有的散在坏死癌巢中无细胞结构。
Normal cervical epithelium was negative staining; CIN group was weak staining in basal layer and/ or prickle cell layer; In cervical carcinoma group, the positive granulas were strongly staining around cancer nests, blood vessels and glands. 正常宫颈上皮未见明显着色;CIN组阳性表达见于基底层和棘细胞层,着色较深;宫颈癌组主要在癌巢周边表达,着色深,血管及腺体周围也有表达。
Mesenchymal tissues around the cancer nests were loose and rich in lymphocytes. 癌巢周围间质较为疏松并有大量淋巴细胞浸润。
