ObjectiveTo explore the relationship between p53 mutation in 5-8 exons and type of epithelial ovarian cancer (EOC) pathogenesis of Han nationality women. MethodsFrom August 2011 to December 2012, 45 patients with primary EOC (Han nationality women from Sichuan Province) diagnosed surgically and pathologically were selected. Using direct DNA sequencing, we analyzed the mutations of p53 in 5-8 exons of all cases, and the EOC patients were divided into two types according dualism and the pathogenesis results. The p53 mutation of the different types in EOC patients were analyzed. ResultsThe frequency and efficiency of p53 mutation in type-ⅡEOC patients were significantly higher than that in typeⅠ(P < 0.01). And the codon 175 might be a mutational hotspot of type-ⅡEOC. The malignant degree and oviduct involved frequency of type-ⅡEOC were obviously higher than that of type-I EOC; p53 mutation frequency in high malignant patients increased significantly. Conclusionsp53 mutation plays an important role in the development of type-ⅡEOC. The codon 175 might be a mutational hotspot of type-ⅡEOC.
目的：探讨宫颈微小偏离性腺癌的诊断与治疗。方法：按照WHO(2003)宫颈腺癌分类标准，回顾性分析我院收治的8例宫颈微小偏离性腺癌的临床病理资料。结果：宫颈微小偏离性腺癌占同期收治宫颈浸润腺癌的4.73％，临床表现为水样白带和/或生殖道出血、宫颈肥大变硬和赘生物，阴道B超检查示宫腔积液，宫颈细胞学诊断较困难，常需深部活检组织诊断。结论：诊断应结合临床表现，影像学检查，宫颈细胞学。当高度怀疑时应取深部组织或宫颈锥切组织诊断，早期诊治预后较好。
