Area of Science:

  • Oncology
  • Biomedical Engineering
  • Translational Medicine

Background:

  • Non-small cell lung cancer (NSCLC), particularly adenocarcinoma, causes significant global mortality.
  • Individualized treatment is crucial due to genetic heterogeneity and drug resistance in lung adenocarcinoma patients.
  • Patient-derived cells (PDCs) are vital for preclinical drug testing and personalized medicine.

Purpose of the Study:

  • To develop and validate a multidimensional biosensor system for guiding individualized adenocarcinoma treatment.
  • To compare drug responses in 2D and 3D patient-derived cell models.
  • To establish a non-invasive method for preclinical drug screening and response prediction.

Main Methods:

  • Integration of 2D and 3D patient-derived cell (PDC) models with cellular impedance biosensors.
  • Quantification of anti-cancer drug responses using cellular impedance in both 2D and 3D culture environments.
  • Validation of the biosensor system's reliability using in vivo results.

Main Results:

  • 3D cultured cells exhibited significantly higher resistance to anti-cancer drugs compared to 2D cultures.
  • Cell-cell, cell-extracellular matrix, and mechanical interactions in 3D models contribute to enhanced drug resistance.
  • The developed biosensor system demonstrated reliability and effectiveness in predicting drug responses.

Conclusions:

  • Cellular impedance biosensors offer a fast, non-invasive, and quantitative method for preselected drug screening in personalized lung cancer treatment.
  • The multidimensional biosensor strategy aids in predicting drug responses and developing new anti-cancer drugs.
  • This approach supports individualized treatment strategies for adenocarcinoma patients, potentially improving outcomes.
