OBJECTIVE: To investigate factors that contribute to @entity1600 ( @entity1600 ) from clinical cT2-T4 N0M0 (cN0) @entity189 ( @entity189 ), and to predict the risk of occult @entity3 before surgery. METHODS: A total of 121 @entity1 who received surgery were retrospectively analyzed. Relevant factors regarding cervical @entity1600 were analyzed. Multivariate analyses were conducted to predict the region where the @entity3 occurred and prognosis. RESULTS: The overall metastatic rate of cN0 @entity189 was 28.1%. Metastatic rates were 15.4%, 32.5% and 35.7% for T2, T3 and T4, respectively. Metastatic rates for @entity189 levels II, III and IV were 19.6%, 17.2% and 3.6%, respectively. A regression equation was formulated to predict the probability of @entity3 in cN0 @entity189 as follows: Pn=e((-3.874+0.749T3+1.154T4+1.935P1+1.750P2))/[1+e((-3.874+0.749T3+1.154T4+1.935P1+1.750P2))]. Approximately 0.2% of @entity1 experienced @entity1600 with no recurrence of @entity5 . Comparison of the intergroup survival curves between @entity1 with and without @entity1600 indicated a statistically significant difference (P=0.029). CONCLUSIONS: Cervical lymph node metastatic rates tended to increase in tandem with T stage in @entity1 with @entity1600 in cN0 @entity189 , and neck dissection is advised for these @entity1 . Moreover, cervical @entity1600 in cN0 @entity189 showed a sequential pattern and may be predicted.
