Flow cytometry as a diagnostic method for colorectal cancer

Area of Science:

• Oncology
• Pathology
• Biophysics

Background:

• Intraoperative histopathology aids surgical decisions but faces diagnostic challenges due to limited specimen size.
• Accurate diagnosis of solid tumors is hindered by the low detection capability for DNA aneuploidy (aneuploidy) compared to hematopoietic cancers.
• Quantitative analysis of whole tissue specimens can improve diagnostic accuracy.

Purpose of the Study:

• To introduce and evaluate a novel quantitative method, the FFT-AUC method, for improving intraoperative histopathological diagnosis of solid tumors.
• To enhance the detection of DNA aneuploidy in cancer tissues using fresh tissue analysis.
• To establish new classification criteria for improved diagnostic accuracy.

Main Methods:

• A new method, the FFT-AUC method, was developed using fresh tissue samples.
• Histograms from cancer and normal tissues were compared.
• Fast Fourier Transform (FFT) patterns were analyzed from these histograms.
• The area under the FFT pattern (AUC) was calculated and compared between tissues.

Main Results:

• The FFT-AUC method demonstrated good results in distinguishing between cancer and normal tissues.
• Analysis of AUC and FFT patterns provided valuable quantitative data for diagnosis.
• The method showed potential for improving the detection of DNA aneuploidy in solid tumors.

Conclusions:

• The FFT-AUC method offers a promising approach to enhance intraoperative histopathological diagnosis.
• Quantitative analysis of fresh tissue using FFT and AUC can overcome limitations of traditional methods.
• This technique has the potential to improve accuracy in diagnosing solid cancers.
