Notch-1 and Ki-67 receptor as predictors for the recurrence and prognosis of Kimura’s disease

摘要

Kimura’s disease (KD) is a rare chronic disease with unknown origin. It remains controversial in KD’s diagnosis, treatment, transformation and need further research. The aim of this study is to investigate the clinicopathologic features of KD and the relationship between the expression of Notch-1, Ki-67 receptor and the recurrence of KD. The hematoxylin and eosin sections and clinical data of 40 patients diagnosed with KD were examined retrospectively. Specimens were available in these 40 cases. Notch-1 and Ki-67 expression were examined using IHC (immunohistochemistry staining) analysis. Of 40 cases of KD (average age, 38.4 years; median age, 36.0 years), 34 cases (85.0%) were clinically seen to involve swelling of the head and neck region. Notch-1 and Ki-67 have a high expression in recurrent patients. High expression of Notch-1 receptor and Ki-67 tended to be found in patients who relapsed. This is the first study to discuss the correlation among Notch-1, Ki-67 and recurrent KD. These results suggest both of the markers may act as promising predictors for the recurrence and prognosis of KD. However, Notch-1 immunoexpression had no statistically significant association with the Ki-67 proliferation index.
