Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no technology for assessing the risk of stomach cancer onset after removing Helicobacter pylori, leading to continuous anxiety and unnecessary medical checks, which increases costs and resource utilization.
Innovation Solution
A method and kit for detecting the expression of the KK-LC-1 gene in stomach tissue samples using RT-PCR, involving specific primers and probes, and optionally a single-stranded nucleic acid fragment to suppress genomic DNA amplification, allowing for accurate risk assessment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If regular medical checkups are performed for all successful removal cases, then cancer detection capability is maintained, but medical costs and medical resources increase
Solution Approach 1:
The patent changes the detection parameter from general cancer screening to specific KK-LC-1 gene expression detection. By using molecular biology parameters (gene expression levels) instead of general clinical parameters, the system can identify high-risk patients who need intensive monitoring while allowing low-risk patients to be managed with reduced monitoring, thus optimizing medical resource allocation while maintaining cancer detection capability.
Solution Approach 2:
The patent replaces the mechanical/system-based approach of general physical examination and imaging with a molecular biology-based detection system. By substituting general clinical checks with specific molecular marker detection (KK-LC-1 gene expression), the system achieves more precise risk stratification that allows for personalized monitoring intensity, reducing unnecessary medical resources while maintaining detection reliability for high-risk cases.
2Reliability
If general cancer screening is performed for all patients, then cancer detection coverage is maximized, but patient anxiety and cost increase without benefit
Solution Approach 1:
The patent applies local quality by detecting KK-LC-1 gene expression specifically in stomach tissue samples from patients with Helicobacter pylori infection. This localized molecular detection identifies which patients have elevated cancer risk at the tissue level, allowing for targeted monitoring and reducing unnecessary anxiety and costs for patients with normal KK-LC-1 expression while maintaining detection coverage for those at high risk.
Solution Approach 2:
The patent introduces KK-LC-1 gene expression as an intermediary marker between Helicobacter pylori infection and stomach cancer development. This molecular intermediary provides objective risk assessment data that mediates between the infection status and cancer risk, allowing patients to understand their actual risk level and reducing anxiety caused by uncertainty about cancer development probability.
3Device complexity
If no risk assessment technology is used, then medical system simplicity is maintained, but continuous anxiety and unnecessary checks increase
Solution Approach 1:
The patent performs preliminary action by detecting KK-LC-1 gene expression in stomach tissue samples at the time of Helicobacter pylori removal or during initial workup. This preliminary molecular risk assessment identifies high-risk patients before they develop cancer, allowing for targeted monitoring strategies that prevent unnecessary checks in low-risk patients while maintaining vigilance in high-risk patients, thus reducing time loss from unnecessary examinations.

AI summary
A method for assessing a risk of onset of stomach cancer in a patient after removing Helicobacter pylori, the method including: a step of detecting expression of a KK-LC-1 gene in a stomach tissue sample derived from the patient before removing Helicobacter pylori, in which positive expression of the KK-LC-1 gene indicates that there is a risk of onset of stomach cancer in the patient after removing Helicobacter pylori.
