Summary
Morphofunctional staging, combining histological differentiation and cell polarization, is a valuable prognostic tool for colorectal cancer. This method correlates with carcinoembryonic antigen (CEA) levels and patient survival outcomes.
Area of Science:
- Oncology
- Biomarkers
- Cancer Research
Background:
- Accurate diagnosis, prognosis, and improved treatment outcomes for colorectal cancer (CRC) require novel, efficient biomarkers.
- Current strategies for CRC management necessitate advancements in identifying reliable prognostic indicators.
Purpose of the Study:
- To analyze the functional and morphological features of colorectal cancer.
- To identify specific neoplastic patterns influencing patient survival.
- To establish a novel morphofunctional staging system for CRC.
Main Methods:
- Followed 45 colorectal cancer patients for at least 3 years.
- Measured plasma carcinoembryonic antigen (CEA) via chemiluminescence.
- Performed immunohistochemical analysis of tissue CEA expression with computer-assisted image processing.
- Classified tumors into morphofunctional classes based on histological differentiation and CEA cell polarization.
- Defined morphofunctional staging by combining morphofunctional class and TNM staging.
Main Results:
- Increased tissue CEA expression correlated with reduced histological differentiation (P = 0.01) and polarization capacity (P = 0.03).
- Tissue CEA quantities increased progressively with the morphofunctional grading system.
- Plasma CEA levels were elevated in advanced tumor and morphofunctional stages (P = 0.001).
- Morphofunctional staging showed a significant relationship with patient survival outcomes (P = 0.005).
Conclusions:
- Morphofunctional staging serves as a valuable prognostic factor in colorectal cancer.
- The proposed morphofunctional staging system correlates effectively with plasma CEA levels.
- This staging approach offers improved prognostic insights for colorectal cancer patients.
