Clinical significance of accurate identification of @entity1600 status in XXXX .

PURPOSE: The clinical consequences of accurately identifying @entity1600 ( @entity1600 ) status in @entity356 ( @entity356 ) are unclear. We aimed to determine the prognostic significance of N stage, positive @entity1600 (PLN) count, and the positive @entity1600 ratio (LNR). We also retrospectively compared survival outcomes of @entity356 @entity1 stratified by @entity1600 dissection (LND). RESULTS: LND was performed in 1593 @entity1 . The @entity49206 was significantly different between groups divided according to N stage, PLN, and LNR in @entity356 @entity1 who underwent LND. Lower LNR was an independent predictor of longer survival in all kinds of @entity1 cohorts, whereas PLN was not such a predictor. PLN count correlated with LND number and LNR. No correlation existed between LNR and LND number. Undergoing LND and having a higher number of dissected LNs were associated with superior @entity49206 . MATERIALS AND METHODS: Data from 1889 @entity356 @entity1 treated between 2004 and 2009, and documented in the Surveillance, Epidemiology, and End Results (SEER) registry, were reviewed. Pearson's correlation coefficient and the Chi-square test were used to study the relationships between LND number, PLN count, N stage, and the LNR. @entity49206 was evaluated using Kaplan-Meier analysis, with the log-rank test performed for univariate analysis (UVA) and the Cox proportional hazards model employed for multivariate analysis (MVA). CONCLUSION: @entity1600 metastatic variables play important roles in the prognostic evaluation and treatment decisions of @entity356 @entity1 . Accurate identification of @entity1600 status in @entity356 @entity1 is critical. LND performance is associated with increased survival and has clinical practicability.
