The Cancer Genome Atlas Prostate Adenocarcinoma Collection

<p>The Cancer Genome Atlas Prostate Adenocarcinoma (TCGA-PRAD) data collection is part of a larger effort to build a research community focused on connecting cancer phenotypes to genotypes by providing clinical images matched to subjects from <a href="http://cancergenome.nih.gov/">The Cancer Genome Atlas (TCGA)</a>. Clinical, genetic, and pathological data resides in the <a href="https://portal.gdc.cancer.gov/exploration?filters=%7B%22op%22%3A%22and%22%2C%22content%22%3A%5B%7B%22op%22%3A%22in%22%2C%22content%22%3A%7B%22field%22%3A%22cases.project.program.name%22%2C%22value%22%3A%5B%22TCGA%22%5D%7D%7D%2C%7B%22op%22%3A%22in%22%2C%22content%22%3A%7B%22field%22%3A%22cases.project.project_id%22%2C%22value%22%3A%5B%22TCGA-PRAD%22%5D%7D%7D%5D%7D">Genomic Data Commons (GDC) Data Portal</a> while the radiological data is stored on The Cancer Imaging Archive (TCIA). </p><p>Matched TCGA patient identifiers allow researchers to explore the TCGA/TCIA databases for correlations between tissue genotype, radiological phenotype and patient outcomes. Tissues for TCGA were collected from many sites all over the world in order to reach their accrual targets, usually around 500 specimens per cancer type. For this reason the image data sets are also extremely heterogeneous in terms of scanner modalities, manufacturers and acquisition protocols. In most cases the images were acquired as part of routine care and not as part of a controlled research study or clinical trial. </p><h3>CIP TCGA Radiology Initiative</h3><p>Imaging Source Site (ISS) Groups are being populated and governed by participants from institutions that have provided imaging data to the archive for a given cancer type. Modeled after TCGA analysis groups, ISS groups are given the opportunity to publish a marker paper for a given cancer type per the guidelines in the table above. This opportunity will generate increased participation in building these multi-institutional data sets as they become an open community resource.  Learn more about the <a href="/display/Public/CIP+TCGA+Radiology+Initiative">CIP TCGA Radiology Initiative</a>.</p>

《癌症基因组图谱前列腺腺癌（TCGA-PRAD）》数据集是构建一个致力于将癌症表型与基因型相联系的研究社区的一部分，该社区通过提供与来自《癌症基因组图谱》（TCGA）项目受试者相匹配的临床图像来实现。临床、遗传和病理数据存储在《基因组数据通用平台》（GDC）数据门户中，而影像学数据则保存在《癌症影像学存档》（TCIA）中。匹配的TCGA患者标识符允许研究人员探索TCGA/TCIA数据库，以研究组织基因型、影像学表型和患者预后之间的相关性。TCGA的样本收集来自全球多个地点，以实现其累积目标，通常每种癌症类型约为500个样本。因此，图像数据集在扫描器模式、制造商和采集协议方面也极为异质。在大多数情况下，图像是作为常规护理的一部分获取的，而不是作为受控研究或临床试验的一部分。

《CIP TCGA影像学倡议》

影像源站点（ISS）小组正在由为特定癌症类型提供影像数据的机构参与者组成并管理。借鉴TCGA分析小组的模式，ISS小组有机会根据上表中的指南为特定癌症类型发表标记论文。这一机会将促进更多机构参与构建这些多机构数据集，因为它们将成为开放的社区资源。了解更多关于《CIP TCGA影像学倡议》的信息。

背景与挑战

背景概述

该数据集是TCGA前列腺腺癌（TCGA-PRAD）数据收集的一部分，旨在通过提供与TCGA受试者匹配的临床图像，连接癌症表型与基因型，以促进研究。数据集整合了临床、遗传、病理和放射学数据，允许探索基因型、放射表型与患者结果之间的相关性。数据来源广泛，具有高度异质性，图像多来自常规护理而非受控研究。
