tcga-brca-titan-idc-ilc
收藏资源简介:
该数据集是TCGA-BRCA(乳腺浸润癌)全切片图像(.svs格式)的子集,源自TITAN论文(Mahmood Lab)的TCGA-OT数据集。通过筛选project_id == TCGA-BRCA从TITAN原始的三份分割文件(tcga-ot_train.csv、tcga-ot_val.csv、tcga-ot_test.csv)中提取,保留了OncoTreeCode列(包含IDC——浸润性导管癌和ILC——浸润性小叶癌两类),用于BRCA亚型分类(IDC vs ILC)的基准测试。数据来自NIH的基因组数据共享平台(GDC),图像为诊断性切片,访问权限为开放。总共包含1049个slide,其中1046个(99.7%)已成功下载并上传,3个slide因GDC不再提供而无法获取。标签分布:IDC 838个(79.9%),ILC 211个(20.1%)。仓库结构包括labels/(存放已过滤的BRCA标签和分割CSV文件)和svs/(存放.svs文件)。该数据集仅用于非商业学术研究,遵循CC-BY-NC-ND 4.0许可证,使用TITAN的分割和标签时需注明来源,且不得创建衍生作品进行再分发。
This dataset is a subset of TCGA-BRCA (Breast Invasive Carcinoma) whole slide images in .svs format, derived from the TCGA-OT dataset of the TITAN paper (Mahmood Lab). It was extracted by filtering project_id == TCGA-BRCA from the original three split files of TITAN (tcga-ot_train.csv, tcga-ot_val.csv, tcga-ot_test.csv), retaining the OncoTreeCode column (including IDC—Invasive Ductal Carcinoma and ILC—Invasive Lobular Carcinoma) for benchmarking BRCA subtype classification (IDC vs ILC). The data comes from NIHs Genomic Data Commons (GDC) platform, with diagnostic slides and open access. It contains a total of 1049 slides, of which 1046 (99.7%) have been successfully downloaded and uploaded; 3 slides were unavailable due to GDC no longer providing them. Label distribution: IDC 838 (79.9%), ILC 211 (20.1%). The repository structure includes labels/ (containing filtered BRCA labels and split CSV files) and svs/ (containing .svs files). This dataset is intended for non-commercial academic research only, under the CC-BY-NC-ND 4.0 license. When using TITANs splits and labels, proper attribution is required, and no derivative works may be created for redistribution.
数据集概述:tcga-brca-titan-idc-ilc
基本信息
- 数据集名称:tcga-brca-titan-idc-ilc
