Construction of an AI-Assisted Pedigree Mapping System for Hereditary Gynecological Tumors: Algorithm Development and Pilot Validation Study

Background: Pedigree mapping serves as the first step in genetic counseling. Traditional methods relying on manual pedigree drawing and information collection are inefficient and prone to errors. Objective: This study aimed to design an intelligent pedigree mapping system based on a specialized model, intended to automate family history collection and standardized pedigree map generation through conversational interaction, thereby enhancing the clinical efficiency of genetic counseling. Methods: This study adopt…

In brief

Researchers built an interdisciplinary, participatory-design system around a specialized large language model for gynecologic oncology. Over four iterative cycles they added retrieval-augmented knowledge bases and a graph-based kinship inference and validation module so patients could give family history in conversation and receive a standardized pedigree map.

Pedigree mapping is the first step of genetic counseling, and manual drawing and data collection are described as inefficient and error-prone. The pilot results are encouraging, but they are preliminary, and the authors say the tool still needs pilot clinical validation before it could be integrated into routine clinical workflows.

Main points

  1. The team included gynecologic oncologists, genetic counselors, AI engineers, and patient representatives.
  2. The knowledge base grew from 100 core information nodes and about 800 expression examples to 245 nodes and 2256 examples.
  3. The system combines retrieval-augmented generation with a graph-based kinship inference and validation module.
  4. Test users rated innovation, ease of use, and clarity of information presentation positively.

The gain

A specialized language model system that collects family history through conversation and builds standardized pedigree maps showed accurate node and relationship generation and positive user feedback in a pilot, suggesting it could ease genetic counseling workflows.

The rundown

The system uses a proprietary specialized large language model with a microservices architecture, including a pedigree data collection component, to automate family history collection through dialogue.

Performance was improved by optimizing dialogue strategies, expanding the knowledge base, and applying self-developed algorithms to raise data extraction accuracy. The AI function was limited in the early stage but improved in later iterations.

Evaluation covered the accuracy of pedigree map generation and user feedback on usability. The authors conclude the tool is an accurate, efficient auxiliary tool with promising preliminary performance.
