Abstract
目的:探讨宫颈浸润性复层产黏液的癌(ISMC)临床病理学特征、诊断及鉴别诊断。方法:复查2017年1月至2019年8月福建医科大学附属第二医院所有宫颈癌病例,从中筛选出3例宫颈ISMC,收集其临床资料,观察组织形态和免疫表型,结合文献复习,分析ISMC临床病理学特征及鉴别诊断。结果:3例患者年龄38~48岁。临床均表现为阴道接触性出血。人乳头状瘤病毒(HPV)检测3例均伴18型阳性。镜检ISMC细胞呈复层排列,形成圆形或不规则形细胞巢,细胞巢最外层细胞呈有极向的栅栏状排列,内层细胞极向紊乱,胞质内富含黏液。3例ISMC均伴发宫颈普通型腺癌,1例同时伴发鳞癌。免疫表型:P16弥漫阳性,P40、CK5/6示巢外层细胞阳性。特殊染色阿辛兰提示内层细胞胞质内黏液丰富。1例术后1个月肺部多发转移;1例术后12个月盆腹腔多发转移。结论:ISMC具有独立的病理组织学特征且预后差,诊断需结合免疫表型及特殊染色,并需要与宫颈非角化型鳞癌等多种类型肿瘤进行鉴别。

  • Pretraining has recently greatly promoted the development of natural language processing (NLP)
  • We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
  • We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
  • The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
  • Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
