While integrating diverse fragmentomic signals can improve accuracy, high modality dimensionality, and limited samples challenge effective multimodal fusion. We present Early-Late fusion with Sample-Modality evaluation (ELSM), a two-stage neural network integrating 13 fragmentomic feature spaces with sample-wise modality evaluation to capture complementary signals. Across five datasets of 1994 samples from 10 cancer types, ELSM outperforms unimodal and advanced multimodal models for cancer detection and tissue-of-origin prediction, achieving an AUC of 0.972 for pan-cancer diagnosis and 0.922 in an independent gastric cancer cohort, with a median tissue-of-origin accuracy of 0.683. Analysis of key genomic regions identified by ELSM reveals robust interpretability aligned with known oncogenic pathways. ELSM provides a powerful and interpretable framework for integrative multi-omics analysis with strong potential for clinical translation in early cancer detection.PMID:41206952 | PMC:PMC12597089 | DOI:10.1093/bib/bbaf599
