Hypothesis
Do T4a tumors have worse survival rates compared to T4b tumors in Stage II colorectal cancer?
Conclusion
Patients with pathologic T4aN0M0 CRC show a trend toward better 10-year overall survival compared to those with T4bN0M0, but this trend lacks statistical significance.
Supporting Evidence
- The 10-year cancer-specific survival rates for pT4a and pT4b were 72.5% and 56.5%, respectively.
- Patients receiving adjuvant chemotherapy had significantly better prognosis.
- There was no significant difference in prognosis between oral 5-FU and FOLFOX.
Takeaway
This study looked at patients with a specific type of colon cancer and found that those with one type of tumor might live a bit longer than those with another type, but the difference isn't big enough to be sure about.
Methodology
A retrospective analysis of 132 patients with pathologic Stage IIc disease (T4a-bN0M0) was conducted, focusing on survival rates and risk factors.
Potential Biases
Variations in individual preferences among treating physicians may have influenced treatment decisions.
Limitations
The study is limited by its single-center design, potential selection bias, and a relatively small sample size.
Participant Demographics
The study included 132 patients, with 90 classified as T4a and 42 as T4b, with no significant differences in age or gender distribution.
