Hypothesis
This study investigates the correlation between genetic polymorphisms and early relapse in high-risk colorectal cancer patients.
Conclusion
The ERCC2 2251A>C genetic polymorphism is associated with an increased risk of early relapse in colorectal cancer patients.
Supporting Evidence
- Patients with the ERCC2 2251AC or 2251CC genotypes had a significantly increased risk of early relapse.
- The study found significant correlations between genetic polymorphisms and early relapse in colorectal cancer.
- The unfavorable genotype ERCC2 2251A>C was significantly correlated with early relapse.
Takeaway
Some people with colorectal cancer have genes that make them more likely to get sick again after treatment, and this study found one specific gene that is linked to that risk.
Methodology
The study assessed six gene polymorphisms in 201 colorectal cancer patients using PCR-RFLP and DNA sequencing.
Potential Biases
Potential biases may arise from the hospital-based design and patient selection criteria.
Limitations
The study is preliminary and based on a relatively small sample size.
Participant Demographics
The study included 201 Taiwanese patients, with a median age of 62.09 years, consisting of 58.7% males and 41.3% females.
