OBJECTIVE: To study the feature and prevention of local recurrences and nodal @entity3 of @entity189 after operation. METHOD: Seventy-six @entity1 with @entity189 were reviewed retrospectively. The relationship among the region involved by @entity5 , local recurrences, @entity5 stage and neck dissection was compared with multiple-factors stepwise regression. The relationship between the region involved by @entity5 and local recurrences was compared with chi-square test. RESULT: In this group of 76 @entity1 with @entity189 had been followed-up for 3 years, the 1-year and 3-year survival rate were 97.4% and 92.1%. Eleven had occurred local recurrences and/or cervical lymph node @entity3 after operation. Six of thirty-five @entity1 (17.1%) whose anterior commissure was involved had recurrences during the follow-up period. There were no local recurrences in another 41 @entity1 . Three of twelve @entity1 whose @entity5 with subglottic extension (extension more than 5 mm below the glottiis) were found paratracheal lymph node (PTLN) @entity3 , one of which was lower jugular lymph node @entity3 . The @entity5 with supraglottic extension or @entity5 with subglottic extension which invaded less than 5 mm weren't found PTLN @entity3 . By analysis of stepwise regression, it was found if there were the @entity3 of PTLN and lower jugular lymph node, the @entity5 often extend to the subglottic (P < 0.05). There is no difference between local recurrences and the @entity5 with or without involved anterior commissure (P > 0.05). CONCLUSION: The @entity5 with subglottic extension may occur PTLN and lower jugular lymph node @entity3 . The @entity5 with involved anterior commissure are considered to be more at risk for local recurrences.
