该文报道了63例非何杰金氏淋巴瘤,应用流式细胞仪分析瘤细胞DNA含量和合成期比率。结果表明:1.DNA指数为0.91~1.57,均值为1.23;2.非整倍体率为76.19%(48/63例),以DNA超二倍体为主;3.S期比率和细胞增殖指数分别为20.56%和35.68%。该文发现高度恶性组比中度恶性组,结外组比结内组肿瘤有较高的细胞DNA含量和合成期比率。光镜下观察的核分裂计数与增殖活性之间无相关性。提示流式细胞分析有助于非何杰金氏淋巴瘤的诊断及其恶性度的估价。 相似文献

女阴白色病变为妇科常见病。近年来国内外作者对此诊断命名及其癌变潜能作了认真探讨。本文根据临床资料结合文献提出浅见。材料和方法自1972年2月~1980年1月我院附属医院妇科拟诊“女阴白斑”病例共330例,初诊时送病理活检。同时,临床送检女阴鳞癌伴白斑病例的外阴根治术术后标本4例,作对照观察。 相似文献

Fifty cases of nasopharyngeal carcinoma were analysed by flow cytometry for DNA index (DI) and cytokinetics in order to study their relation with histopathology and prognosis. The results showed that DI values ranged from 0.96 to 1.96 with an average of 1.58; aneuploid frequency was 94% (47/50 cases); higher %S+G2M or PI was found; the 5 year survival rate was 26.47%. Cross comparison of these data indicated that 1. vesicular nuclear cell carcinoma was different from the poorly differentiated squamous cell carcinoma as to DI and aneuploid frequency, supporting the former as an independent clinico-pathological type; 2. DI, aneuploid frequency, cytokinetics and prognosis were not significantly different in the pale even nuclear and dark granular nuclear patterns of poorly differentiated squamous cells carcinoma and 3. there were higher %S+G2M values in all the three groups (vesicular, pale even and dark granular nuclear patterns). 相似文献

本文报导36例头颈部小涎腺圆柱瘤型腺癌病例。这些恶性肿瘤缓慢无痛性生长,术后易复发,但患者常带瘤生存多年。筛状结构是典型的病理组织学特征。病理学分型可分为筛状形和实体型两类,但似乎与预后关系不明显。最重要的预后因素为手术标本切缘有无癌组织。作者推测了瘤团内“微囊肿”和“腺管”样结构的组织发生。 相似文献

腺样囊性癌(简称ACC,)为具有特殊生物学行为的涎腺恶性肿瘤。最早由Robin和Laboulbene(1853)以异位腺瘤报道了鼻腔、副鼻窦ACC。肿瘤表现进展缓慢、术后复发、倾向侵犯神经干和能长期带瘤生存等特征。本文以我院收治的大小涎腺ACC22例并附有随访资料(1970~1983年),对肿瘤的病理分型、预后和组织发生作初步探讨。病理标本经常规石蜡切片、H.E.染色,部分病例作PAS和爱先兰(Alcain blue)染色。 相似文献
