Summary
Flow cytometry is valuable for diagnosing cancer by measuring DNA content and ploidy. While prognosis and treatment monitoring remain challenging, further research into other cellular components is recommended.
Area of Science:
- Clinical cytometry
- Oncology
- Biomedical engineering
Background:
- Flow cytometry has become a key technique in clinical diagnostics over the past decade.
- Primary applications involve measuring cellular DNA content for cell cycle distribution and ploidy analysis.
- Significant data exists on aneuploidy in various malignant diseases.
Purpose of the Study:
- To survey the clinical applications of flow cytometry.
- To evaluate its diagnostic and prognostic value in oncology.
- To identify areas for future development in flow cytometry applications.
Main Methods:
- High-resolution measurements of cellular DNA content.
- Analysis of cell cycle distribution and ploidy.
- Review of existing clinical data and applications.
Main Results:
- Abnormal DNA content detected by high-resolution flow cytometry has diagnostic value in several tumor types when used with conventional methods.
- The prognostic significance of DNA aberrations is not yet established.
- Monitoring cancer treatment via cell cycle distribution has shown limited success due to tumor complexity and interpretation challenges.
Conclusions:
- Flow cytometry is a valuable diagnostic tool in oncology, particularly for DNA content analysis.
- Further advancements require exploring other cellular constituents beyond DNA, using single or multiparameter measurements.
