Results: There were 727 included cases. There was a concordance rate of 92.98% (676/727 patients) between the intraoperative diagnosis and permanent section diagnosis. The sensitivity rate was 81.86% while the specificity rate was 98.00%. Positive predictive value was 94.87% while negative predictive value was 92.29%. The accuracy rate was 92.98%. The period prevalence of cancer and/or positive margin was 31.09%. Conclusion: The frozen section accuracy in Rajavithi Hospital is in line with other institute in the literature.
