Computational Methods and Challenges in Cell-Free DNA Analysis for Multi-Cancer Early Detection
arXiv:2606.20174v1 Announce Type: new Abstract: Cell-free DNA (cfDNA) is a promising avenue for non-invasive multicancer early detection (MCED), in that, it can enable multiple cancer detection simultaneously from a single blood draw, with particular sensitivity to cancers that currently lack established screening programs. Here we review the computational methods developed between 2022 and 2025 for cfDNA-based MCED. We focus on how fragmentomics and epigenetic features are extracted and analyzed to detect cancer at early stages. We first briefly outline the biological basis of cfDNA signals,
The rapid advancement in AI, specifically in computational methods between 2022-2025, is enabling sophisticated analysis of cfDNA for multi-cancer early detection, transitioning this field from research to practical application.
Non-invasive multi-cancer early detection (MCED) through cfDNA analysis represents a significant paradigm shift in healthcare, potentially enabling earlier and more effective cancer interventions.
The ability to detect multiple cancers simultaneously from a single blood draw, especially for cancers lacking current screening programs, fundamentally changes early detection strategies and access to care.
