Summary

This summary is machine-generated.

An AI tool called DeepGEM can predict lung cancer gene mutations from standard histology slides, offering a fast and affordable alternative to traditional genomic testing for better treatment planning.

Area Of Science

  • Oncology
  • Computational Biology
  • Medical Imaging

Background

  • Accurate driver gene mutation detection is vital for lung cancer prognosis and treatment.
  • Conventional genomic testing is limited by tissue requirements and resource intensity.
  • An AI-driven approach is needed for accessible mutation prediction.

Purpose Of The Study

  • To develop an annotation-free AI method (DeepGEM) for predicting gene mutations from histological slides.
  • To evaluate DeepGEM's performance on internal, external, and public datasets.
  • To assess the model's generalizability to lymph node metastasis biopsies.

Main Methods

  • A multicentre retrospective study involving 3637 lung cancer patients with paired pathology images and mutation data.
  • Development of a co-supervised multiple instance learning model with label disambiguation.
  • Validation on internal, external (15 hospitals), and The Cancer Genome Atlas (TCGA) datasets.

Main Results

  • DeepGEM demonstrated robust performance across all datasets, with AUC values ranging from 0.76 to 0.97.
  • The model accurately predicted mutations in both excisional and aspiration biopsy samples.
  • Generalization to lymph node metastases was confirmed, with high AUC for EGFR and KRAS mutations.

Conclusions

  • An AI-based method (DeepGEM) provides accurate, timely, and economical prediction of gene mutations and their spatial distribution.
  • DeepGEM shows significant potential as an assistive tool for guiding lung cancer clinical treatment.
  • The AI method overcomes limitations of conventional genomic testing, especially in resource-limited settings.
