Inter-quartile after normalization on the reference gene set. cP for Spearman rank correlation test. dP for Mann-Whitney U test. eP for Kruskal-Wallis test, including a Wilcoxon-type test for trend when appropriate. fWith quantitative polymerase chain reaction cut point for positive versus negative ESR1 and PGR, 0.2 and 0.1, respectively, and for ESR2 at the median level of 0.005 (mRNA levels rela

Me PCR conditions for these SYBR-based assays were as described previously [16,17]. Forty rounds of amplification were performed, and fluorescent signals of the Taqman probe or SYBR green signal were used to generate cycle threshold (Ct) values from which mRNA expression levels were calculated. Ct values of HPRT1 and B2M were adjusted to the higher HMBS Ct values. Next, the expression levels of DC

Receptors also modulate response to therapy [8,9], we also assessed, as a secondary aim of this study, the predictive value of DC-SCRIPT by using clinical benefit and progression-free survival (PFS) after first-line tamoxifen for advanced disease as the main endpoints.Materials and methodsPatientsdetermined by real-time reverse transcriptase-polymerase chain reaction (RT-PCR) [14,16,17].

Ltivariable analyses, increasing levels of DC-SCRIPT were associated with good prognosis only for pT1 (small tumor without lymphatic/vascular invasion) tumors and not for larger tumors. These and additional exploratory Cox univariate analyses are summarized in Table 3. The prognostic value of DC-SCRIPT is visualized in KaplanMeier curves (Figure 1) as a dichotomized variable in these biologically
