摘要：

Increased expression of argyrophilic nucleolar organizer regions (AgNORs) has been identified in certain malignant tumors including nasopharyngeal carcinoma (NPC). However, its prognostic significance in NPC is uncertain and remains to be evaluated. To address this we silver-stained 63 paraffin sections of NPC cases, and examined the correlation between AgNOR count and area, calculated by the CAS 200 image analysis system, and tumor behavior, locoregional control, and survival of patients. The mean AgNOR count and area were 1.62 ± 0.31 and 3.98 ± 11.4 μm2, respectively. The AgNOR area was positively associated with T stage (r = 0.26, P = 0.04). The Mann-Whitney test confirmed no significant difference in AgNOR area and count between patients with different outcomes. Multivariate analysis using the Cox proportional hazard model showed neither AgNOR count nor area to be significant predictors of actuarial survival or disease-free survival. It is concluded that AgNOR does not have an independent and significant prognostic value in NPC. AgNOR expression may be merely a reflection of malignant phenotype as well as cellular activity but not necessarily the ultimate behavior of the tumor.
