Hypothesis
We aimed to detect TSP50 expression in CRC, correlate it with clinicopathological factors, and assess its potential diagnostic and prognostic value.
Conclusion
TSP50 is a potential effective indicator of poor survival for CRC patients, especially for those with early-stage tumors.
Supporting Evidence
- High TSP50 expression was found in 68.4% of CRC cases.
- Patients with high TSP50 expression had significantly shorter survival compared to those with low expression.
- High TSP50 expression was identified as an independent risk factor for poor prognosis.
Takeaway
This study found that a protein called TSP50 is found in high amounts in colorectal cancer and can help predict how well patients will do.
Methodology
TSP50 mRNAs and proteins were detected in CRC cell lines and specimens via RT-PCR and Western blot analysis, and immunohistochemical analysis was performed on tissue microarrays.
Limitations
The study's sample size was limited to 95 patients, and further validation in larger studies is needed.
Participant Demographics
Mean age of participants was 55 years, with a range from 23 to 82 years.
