Hypothesis
RCT is superior to SCRT in terms of local recurrence after five years.
Conclusion
The study aims to determine whether combined neoadjuvant radiochemotherapy is more effective than short-course radiotherapy in preventing local recurrence of rectal cancer.
Supporting Evidence
- Previous studies have shown that preoperative radiotherapy reduces local recurrence compared to surgery alone.
- The Swedish Rectal Cancer Trial demonstrated improved overall survival with preoperative short-course radiotherapy.
- The German Rectal Cancer Study Group found preoperative radiochemotherapy better than postoperative treatment for local control.
Takeaway
This study is trying to find out if giving patients a combination of radiation and chemotherapy before surgery helps them more than just giving them radiation alone.
Methodology
Patients with locally advanced rectal cancer are randomized to receive either short-course radiotherapy or combined radiochemotherapy before surgery.
Potential Biases
Potential bias due to the non-comparative nature of previous studies and the mandatory adjuvant chemotherapy in both groups.
Limitations
The study may face challenges in patient recruitment and adherence to treatment protocols.
Participant Demographics
Patients aged 18 and over with histologically proven rectal cancer staged T2N+ or T3.
