诊断试验:

Diagnostic Tests:

金标准或参考标准(即可准确诊断某疾病的单项方法或多项联合方法,在本研究中用于诊断是否有该病的临床参考标准):

TLS病理指标由一位具有10年以上肝脏病理经验的病理学家进行分析,分析同时对其他临床和影像学信息不知情。TLS:a.聚集体:模糊、不明确的淋巴细胞簇;b.初级滤泡:没有生发中心形成的圆形淋巴细胞簇;c.次级滤泡:具有生发中心形成的滤泡。

Gold Standard or Reference Standard (The clinical reference standards required to establish the presence or absence of the target condition in the tested population in present study):

The TLS pathological indicators were analyzed by a pathologist with more than 10 years of liver pathology experience, who was unaware of other clinical and imaging information. TLS: a. Aggregates: fuzzy and unclear lymphocyte clusters; b. Primary follicles: circular lymphocyte clusters without germinal centers; c. Secondary follicles: follicles formed with germinal centers.

指标试验(即本研究的待评估诊断试验,无论为方法、生物标志物或设备,均请列出名称):

组织学苏木精和伊红染色

Index test:

Histological hematoxylin and eosin stains

目标人群(可以是某种疾病患者或正常人群,详细描述其疾病特征,注意应纳入符合分布特点的全序列病例,具有良好的代表性)

病理诊断为肝细胞癌

例数:

Sample size:

700

Target condition (The target condition is a particular disease or disease stage that the index test will be intended to identify. Please specify the characteristics in detail; the population should has a complete spectrum and good representative):

Pathological diagnosis as hepatocellular carcinoma

容易混淆的疾病人群(即与目标疾病不易区分的一种或多种不同疾病,应避免采用正常人群对照的病例-对照设计):

病理诊断为胆管癌和混合型肝癌

例数:

Sample size:

0

Population with condition difficult to distinguish from the target condition, the normal population in a case-control study design should be avoid:

Pathological diagnosis of cholangiocarcinoma and mixed liver cancer
