Area of Science:

  • Oncology
  • Biomedical Optics
  • Medical Imaging

Background:

  • Carcinomas, cancers from epithelial tissue, represent 80-100% of human cancers.
  • Early detection of carcinomas is vital for successful surgical resection and improved prognosis.
  • Current detection methods rely on visual inspection or basic white light tools, which can miss subtle neoplastic changes.

Purpose of the Study:

  • To present integrated multimodality optical imaging and sensing tools for early carcinoma detection.
  • To highlight technologies utilizing intrinsic and extrinsic optical contrast for improved visualization.
  • To discuss applications in detecting common epithelial carcinomas of the skin, GI, GU tracts, and lungs.

Main Methods:

  • Utilizing emerging optical tools based on differential tissue properties (refraction, absorption, scattering, fluorescence).
  • Employing molecularly targeted agents to enhance optical contrast for improved detection.
  • Integrating miniature handheld microscopy with wide-field optical surveillance for rapid detection and biopsy guidance.

Main Results:

  • Demonstrated label-free visualization of neoplasia through intrinsic optical properties.
  • Showcased enhanced optical contrast using targeted agents for improved early detection.
  • Presented integrated systems for multiscale imaging and multiparameter sensing.

Conclusions:

  • Integrated multimodality optical tools offer enhanced contrast for early carcinoma detection at epithelial surfaces.
  • Point-of-care diagnostic capabilities are improved through combined wide-field surveillance and handheld microscopy.
  • These advanced optical technologies hold promise for managing common epithelial carcinomas.
