Precision management of gastrointestinal tumor-associated osteoporosis driven by cutting-edge technologies: Current status, challenges, and future prospects

Table 1 Comparison between traditional management and precision management for gastrointestinal tumor-associated osteoporosis

Items (evaluation indicators)	Traditional management mode	Precision management mode (empowered by cutting-edge technologies)
Core concept	Empirical intervention, one-size-fits-all strategy	Precision medicine, based on individual characteristics (tumor biology, genetic background, bone metabolism status, etc.)
Screening method	Mainly dual-energy X-ray absorptiometry	AI-based opportunistic screening (based on routine imaging) + bone metabolism marker detection
Screening efficiency	Low, about 60% of GTO patients not identified early	High, significantly improved early recognition rate
Therapeutic strategy	Routine bone protectors (bisphosphonates, denosumab) applied uniformly based on guidelines	Nanoparticle-targeted drug delivery system + personalized scheme (combined with multiomics results)
Consideration of individual differences	Ignored (tumor stage, pathological type, treatment plan, genetic background, nutritional status not fully considered)	Fully considered, tailored to individual patient characteristics
Therapeutic effect	Poor in some patients (61.3% failure rate of bisphosphonates in postmenopausal osteoporotic vertebral fracture patients)	Significantly improved, targeted delivery enhances efficacy
Adverse reactions	High risk (atypical femoral fractures, osteonecrosis of the jaw from bisphosphonates; hypocalcemia from denosumab)	Reduced systemic adverse reactions (targeted delivery reduces nontarget organ exposure)
Mechanism understanding	Focus on single bone metabolism pathway (e.g., RANKL-RANK-OPG system)	In-depth analysis via multiomics technologies, clarifying “tumor-gastrointestinal-bone” multisystem interaction network
Management process	Discontinuous (screening → intervention, no closed-loop monitoring)	Whole-process closed-loop management (precision screening → precision assessment → precision intervention → precision monitoring)
Impact on patient compliance	Low (due to poor therapeutic effect and adverse reactions)	High (improved efficacy, reduced side effects, and personalized intervention)
Impact on prognosis	Limited improvement, failure to effectively reduce SREs and prolong survival	Significantly improves long-term prognosis, reduces SREs incidence, and enhances quality of life
Supporting technologies	Conventional detection and drug delivery technologies	AI, nanoparticle-targeted drug delivery system, multiomics (genomics, transcriptomics, metabolomics, microbiomics), MDT collaboration
