Ek of RT, a single year post-RT, and two years post-RT, respectively. 6. Subgroup evaluation I: NCT plus CCRT vs. CCRT alone To validate the role of NCT as well as CCRT, we performed a subgroup evaluation with 71 sufferers. We compared 41 sufferers treated with NCT followed by CCRT and 30 sufferers treated with CCRT alone. The median follow-up for survivors was 63.four months (variety, six.0 to 123.7 months) for sufferers treated with NCT followed by CCRT and 38.six months (variety, 6.three to 102.9 months) for individuals treated with CCRT alone. Overall, NCT didn’t enhance outcomes for any clinical endpoint (Fig. two). Additionally, despite the fact that not statistically considerable, CCRT alone resulted in superior outcomes for each and every endpoints at five years. On the other hand, the N stage (p = 0.007) and AJCC stage (p = 0.035) were additional sophisticated inside the NCT plus CCRT group, and each remained important prognostic components for DMFS and DFS in a univariate analysis of your 71 individuals inside the subgroup evaluation. For that reason, to adjust for the N stage and AJCC stage in DMFS and DFS, we performed additional analysis having a Cox proportional hazard model with two variables simultaneously: N stage with NCT use and AJCC stage with NCT use (final results not shown). For DMFS, the N stage remained significant (p = 0.017), though NCT didn’t affect outcomes (p = 0.790). Similarly, N stage (p = 0.006) and AJCC stage (p = 0.026) both remained considerable for DFS, whilst NCT did not affect final results (p = 0.742 and p = 0.461, respectively). Even so, the significance of AJCC stage on DMFS was diminished (p = 0.952) together with the use of NCT. The use of NCT before CCRT led to increased risk of serious hematologic toxicity in the course of the remedy course (25.4 vs. 7.0 ; p = 0.015). The particulars of patient qualities and survival outcomes of your subgroup evaluation are shown on Tables 5 and 6, respectively. 7. Subgroup evaluation II: CCRT alone vs. CCRT plus ACT Similar to subgroup analysis I, 30 patients treated by CCRT alone were compared to 12 patients treated with CCRT plus ACT. Comparing sufferers treated with CCRT alone with these treated with CCRT plus ACT, the 5-year DMFS, DFS, and OS prices have been 89.4 vs. 66.7 (p = 0.151), 82.5 vs. 66.7 (p = 0.440), and 82.9 vs. 91.7 (p = 0.849), respectively.
