ROI Calculation Logic

Early detection of endometrial cancer could shift 300 patients annually from advanced-stage treatment (average ~$33.5K/patient (AI est.)) to early-stage treatment (average ~$10K/patient (AI est.)), resulting in ~$7M (AI est.) in direct medical cost savings. Further savings could arise from optimized screening frequency.

Speed to Market
3× faster than in-house development
This technology is based on years of fundamental research at Kanazawa University, where the link between BLM functional abnormalities and endometrial cancer onset has been scientifically established. While in-house R&D from scratch could take approximately 5 years from basic research to clinical application, licensing this patent allows leveraging established molecular mechanisms and detection principles. This could accelerate prototype development and transition to clinical validation in approximately 1.5 years, significantly reducing development time and accelerating market entry.

Technical Feasibility
This technology detects functional abnormalities in Bloom syndrome protein (BLM) and is highly compatible with existing biochemical testing systems and genetic analysis equipment (e.g., PCR devices, immunoassay systems). The detection methods described in the patent claims are based on general experimental techniques, requiring no new large-scale capital investment and allowing for integration using existing clinical laboratory infrastructure. This suggests a relatively low technical barrier to adoption.
Success Scenario
Implementing this technology could improve the early detection rate of endometrial cancer by 20% compared to current methods. This would enable earlier intervention, potentially increasing patient treatment success rates. Consequently, it is estimated to significantly contribute to improving patient quality of life and optimizing healthcare costs associated with advanced cancer treatment. Physicians could also develop precise screening plans based on individual patient risk.
