Attenuated total reflection Fourier transform infrared (ATR FT-IR) spectroscopy offers a non-invasive method for breast cancer screening. This technique accurately distinguishes breast cancer patients from healthy individuals using liquid plasma biopsies.
Area of Science:
- Biomedical Engineering
- Analytical Chemistry
- Oncology
Background:
- Breast cancer diagnosis relies heavily on mammography, which has limitations including false results and low patient adherence.
- Existing screening methods can be invasive, costly, and time-consuming, highlighting the need for improved diagnostic tools.
Purpose of the Study:
- To evaluate the clinical applicability of Attenuated Total Reflection Fourier Transform Infrared (ATR FT-IR) spectroscopy for breast cancer screening.
- To assess the potential of ATR FT-IR spectroscopy in distinguishing breast cancer patients from healthy controls using liquid plasma samples.
Main Methods:
- Utilized Attenuated Total Reflection Fourier Transform Infrared (ATR FT-IR) spectroscopy on liquid plasma samples.
- Analyzed spectral data to identify biomarkers differentiating breast cancer patients and healthy controls.
- Focused on spectral variations in protein and amide II bands, specifically around 1500-1515 cm-1.
Main Results:
- ATR FT-IR spectroscopy achieved high accuracy in distinguishing breast cancer patients from healthy controls.
- Demonstrated a sensitivity of 97%, specificity of 93%, and prediction accuracy of 94%.
- Identified distinct spectral differences, particularly in protein and amide II bands, between the two groups.
Conclusions:
- ATR FT-IR spectroscopy is a promising, non-invasive tool for breast cancer screening.
- The technique offers advantages such as cost-effectiveness, speed, and minimal sample requirement.
- Liquid plasma biopsy combined with ATR FT-IR shows significant potential for early breast cancer detection.

Transmittance is defined as the ratio of the radiant power passing through a sample to that from the radiation's source. Multiplying the transmittance by 100 gives the percent transmittance (%T), which varies between 100% (no absorption) and 0%...
