Special Issue Information

Dear Colleagues,

This Special Issue invites original research articles, reviews, and perspectives focused on novel predictive molecular biomarkers critical for advancing cancer diagnosis, prognosis, and therapy response prediction. We seek studies that explore cutting-edge molecular signatures, multi-omics integration, and innovative technologies such as liquid biopsy, spatial omics, and AI-driven biomarker discovery. Emphasis is on biomarkers that enhance understanding of tumor progression mechanisms, therapeutic resistance, immune response prediction, and clinical outcomes across diverse cancer types. Contributions highlighting translational applications and personalized medicine strategies are particularly encouraged. This Issue aims to foster collaboration across disciplines advancing precision oncology through molecular insights. Submitted manuscripts will undergo rigorous peer review according to journal standards. We welcome submissions from early career researchers to established experts to spark impactful discussions and accelerate clinical utility. Join us in shaping the future of cancer biomarker research.

Abstract
Biochemical recurrence (BCR) after radical prostatectomy (RP) remains a major clinical challenge. Although metabolic reprogramming drives prostate cancer (PCa) progression, its predictive value for BCR and its interplay with the tumor immune microenvironment (TIME) remain incompletely understood.

Biochemical recurrence (BCR) after radical prostatectomy (RP) remains a major clinical challenge. Although metabolic reprogramming drives prostate cancer (PCa) progression, its predictive value for BCR and its interplay with the tumor immune microenvironment (TIME) remain incompletely understood. By integrating weighted gene co-expression network analysis (WGCNA) with machine learning, we identified four metabolic-related hub genes (GDPD1, PLA2G7, PTGDS, and SRD5A2) and developed an XGBoost-Cox model that accurately stratified BCR risk (training 5-year AUC: 0.858; validation 5-year AUC: 0.745). SHAP analysis enhanced the model’s interpretability, while immunohistochemistry (IHC) validated differential protein expression of these targets across 32 clinical specimens. Furthermore, immune profiling demonstrated that these genes are closely linked to M2 macrophage-mediated immunosuppression and altered T-cell infiltration. To translate these biomarkers into therapeutic targets, we employed in silico screening, molecular docking, and molecular dynamics simulations, identifying (-)-epigallocatechin gallate (EGCG) as a promising multi-target candidate. Subsequent in vitro assays confirmed that EGCG binds stably to GDPD1, PTGDS, and SRD5A2, effectively suppressing malignant PCa phenotypes and prostate-specific antigen (PSA) secretion. In summary, we established a robust and interpretable model for predicting BCR after RP, and our in vitro validation suggests that EGCG holds promise as a therapeutic agent to delay PCa progression.
