curatedOvarianData is a comprehensive resource for clinically-oriented investigation of the ovarian cancer transcriptome. It provides clinically-annotated expression data for 2,970 patients as 24 expression datasets including The Cancer Genome Atlas (TCGA) microRNA and Affymetrix mRNA microarray datasets. Probesets are mapped to official gene symbols using up-to-date maps. All clinical annotations are hand-curated and machine-checked to ensure consistent syntax and maximum retention of available clinical variables, resulting in nearly 1,500 patients in which overall survival, stage, grade and histology are available. ExpressionSet slots are populated with numerous metadata including PubMed IDs, citations, abstracts, study-specific warnings for retractions and duplicated samples, and probeset <--> gene maps. The package vignette provides examples for selecting patients and datasets based on flexible rules, performing meta-analysis of potential biomarkers, creating publication-ready tables from ExpressionSet metadata, and simple exporting of data tables for non R-users.
