inexpensive, easily calculated, and known to show correlation with prognosis of cancer. The aim of this study was to evaluate the relationship between NLR and prognosis of papillary thyroid carcinoma. Methods: A total of 1,142 patients who underwent total thyroidectomy for papillary thyroid carcinoma between 1995∼2005 at Asan Medical Center were enrolled in this study. Patients were categorized according to two groups based on NLR and clinico-pathological variables and disease survival were
compared between the two groups. Results: Median age of patients was 45.4 years, and the median follow-up period was 48 months. The cut-off value of NLR for prediction of disease-free survival (DFS) was 2. Comparison of DFS between two groups stratified by NLR (NLR ≤2, NLR>2) showed little statistical difference (P=0.48). After adjusting for risk (N stage), there was no significant difference according to N stage (N0: P=0.86, N1a: P=0.4, N1b: P=0.12).Conclusion: NLR did not show correlation with
disease free survival of papillary thyroid carcinoma. 키워드열기/닫기 버튼, , Neutrophil-to-lymphocyte ratio, Papillary thyroid carcinoma, Disease-free survival 피인용 횟수
