Result: Among the 74 patients, nineteen patients (25.7%) experienced recurrent disease. Thirteen patients (17.5%) suffered recurrent disease within 12 months (early recurrence). The median follow-up for non-recurrence was 81.3 months, 17.6 months for early recurrence, and 34.4 months for late recurrence. After Multiivariate analysis, lymph node involvement(odds ratio 4.34, P=0.02), microsatellite instability (odds ratio; 8.01, P<0.01) were significant predictors for early recurrence. Conclusion: Lymph node involvement and microsatellite instability were found to be predictors for early recurrence.
