Core Tip

Core Tip: Short duration radiotherapy was compared to conventional fractionated radiation treatment plus chemotherapy in 100 patients with stage IIIB or more severe rectal cancer to verify whether short duration preoperative radiotherapy had an advantage in diminishing complications, reducing risk of recurrence and improving survival. The findings revealed that there was no significant difference in the incidence of complications between short and long duration radiotherapy plus chemotherapy. However, short duration radiotherapy improved the 1-yr survival rate and reduced the recurrence rate and distant metastasis rate in comparison with conventional preoperative radiotherapy.
