Hypothesis
PAI-1 may serve as a candidate marker for the malignancy of colorectal cancer (CRC).
Conclusion
PAI-1 expression levels are significantly associated with the malignancy and prognosis of colorectal cancer.
Supporting Evidence
- PAI-1 expression scores were significantly higher in lymph node metastasis-positive CRCs compared to negative ones.
- A significant increase in PAI-1 expression scores was observed with the tumour stage.
- Multivariate analysis revealed PAI-1 expression score as a strong independent prognostic factor for CRC.
Takeaway
This study found that a protein called PAI-1 can help doctors understand how serious someone's colorectal cancer is.
Methodology
Quantitative RT–PCR was performed to evaluate PAI-1 gene expression levels in CRC patients.
Limitations
The study was limited to a specific patient population and may not be generalizable.
Participant Demographics
Mean age 64.5 years; range 41–85 years; 55 CRC patients.
