Knowledge about the staging significance of the prostate cancer antigen 3 (PCA3) score to better identify pathologic features after radical prostatectomy (RP) is limited and controversial.
Over subsequent stages significance levels are decreased to avoid stages becoming redundant.
In fact, the stratification by OCT1 level displayed even higher prognostic significance than the widely employed AJCC staging (significance p=0.0002, 5-year survival: 20 vs 42.2 months, figure 2B).
Even at that stage, the significance of U-Cd on an individual basis remains uncertain.
The type of performed GSE analysis is based on the angular distance that encodes for each life cycle stage the significance of the gene set relative to the protein set.
If an interim analysis is carried out, Bonferroni corrections will be applied in the final stage (ie, significance p<0.05 will be changed to p<0.025, which will require a doubling of the number of subjects).
Overall type I error rates, powers and correlations between stages obtained from simulations of designs (i - viii) i - viiis 2 and 3. Key: α1 = stage 1 sinnificance level, ω1 = sTables power, ρ| Hh = correlation between stages under hypothesis Hh, α = overall type I error rate, ω = overall power.
It is important to underline that this is a pilot retrospective study and where survival trends were consistent between OS and RFS for stage stratifications, significance was not always attained when stage subgroups were analysed independently, possibly due to low patient numbers.
Univariate analyses fitting Cox proportional hazards model adjusted for stage showed significance with OS in NSCLC, ADC, and SCC (P < 0.0001, < 0.0001, 0.0055, respectively), and similarly, there was a significant differences between HS and OS in NSCLC, ADC, and SqCC (P < 0.0001, < 0.0001, 0.0002, respectively) [Table 2].
Study limitation: Animal serum is a complex mixture of a large number and variety of components; therefore, it is difficult to assess, at this stage, the significance of the observation that horse serum inhibits the programmed progress of equine airway cells through the lineage of differentiation in cultures.
