PanCancerSig

PanCancerSig generates prognostic gene-expression signatures from whole-transcriptome RNA sequencing data to predict patient survival across multiple cancer types.

Key Features:

• Implementation: Implemented as an R package for analysis of transcriptome data.
• Platform Independence: Employs a statistical framework that is independent of specific RNA sequencing platforms.
• Whole-Transcriptome Signatures: Identifies gene-expression signatures from whole-transcriptome RNA-seq that provide improved prognostic predictions compared to previously reported models.
• Clinical Complementarity: Produces signatures that capture prognostic features not accounted for by traditional clinical variables.
• Biological Insight: Reveals prognostically relevant pathways including immune system and cell cycle processes.

Scientific Applications:

• Prognostic Biomarker Development: Supports development and validation of prognostic biomarkers to inform personalized treatment strategies.
• Cross-Cancer Applicability: Applicable across cancer types with demonstrated effectiveness in ovarian cancer and lung adenocarcinoma.

Methodology:

Applies a novel statistical framework to analyze whole-transcriptome RNA sequencing data and derive prognostic gene-expression signatures that are evaluated against existing models.
