Prognostic factors for survival by multivariate analysis
| Factor | RFS |
OS |
||
|---|---|---|---|---|
| HR | p value | HR | p value | |
| Differentiation (PD vs. MD) | 34.8 | < 0.001 | ||
| Stage (IIIB vs. IIB, IIIA) | 8.5 | 0.118 | 5.4 | 0.037 |
| Nodal stage (N1, 2, 3 vs. N0) | ||||
| Definitive treatment (CCRT vs. surgery) | ||||
| Adjuvant treatment (no vs. yes) | 16.1 | 0.001 | 8.6 | 0.004 |
| Beclin-1 (low vs. high) | 8.2 | 0.011 | ||
RFS, relapse-free survival; OS, overall survival; HR, hazard ratio; PD, poorly differentiated; MD, moderately differentiated; CCRT, concurrent chemoradiation.
