Comparison of 1 year EFS in two groups defined by a range of ∆CT cut points (left column) and corresponding ROC analysis of the ability of ∆CT values above the cutpoint to predict 1 year EFS (right column), for assays based on different combinations of genes. NB5 assay (A, B), Phox2B/TH/DDC (C, D), Phox2B/TH (E, F), Phox2B/TH/Dcx (G, H), Th/Dcx (I, J). These analyses show that the NB5 assay is at least as or more predictive then the other gene combinations.

Change in BM and Blood NB5 �Ct for patients with progressive disease vs. non-progressive disease. Change in NB5 �Ct was assessed between pairs of time points where both NB5 �Ct and clinical disease assessments were performed. Observations are classified by whether there was clinical disease progression or not between the time points.

Correlation of morphologically-defined NB cells in BM and MIBG Curie score. Analysis of BM biopsies and MIBG scans were performed concurrently on 173 patients.

Purpose: We determined whether quantifying neuroblastoma-associated mRNAs (NB-mRNAs) in bone marrow and blood improves assessment of disease and prediction of disease progression in patients with relapsed/refractory neuroblastoma.Experimental Design: mRNA for CHGA, DCX, DDC, PHOX2B, and TH was quantified in bone marrow and blood from 101 patients concurrently with clinical disease evaluations. Correlation between NB-mRNA (delta cycle threshold, ΔCt, for the geometric mean of genes from the TaqMan Low Density Array NB5 assay) and morphologically defined tumor cell percentage in bone marrow, 123I-meta-iodobenzylguanidine (MIBG) Curie score, and CT/MRI-defined tumor longest diameter was determined. Time-dependent covariate Cox regression was used to analyze the relationship between ΔCt and progression-free survival (PFS).Results: NB-mRNA was detectable in 83% of bone marrow (185/223) and 63% (89/142) of blood specimens, and their ΔCt values were correlated (Spearman r = 0.67, P < 0.0001), although bone marrow Ct was 7.9 ± 0.5 Ct stronger than blood Ct. When bone marrow morphology, MIBG, or CT/MRI were positive, NB-mRNA was detected in 99% (99/100), 88% (100/113), and 81% (82/101) of bone marrow samples. When all three were negative, NB-mRNA was detected in 55% (11/20) of bone marrow samples. Bone marrow NB-mRNA correlated with bone marrow morphology or MIBG positivity (P < 0.0001 and P = 0.007). Bone marrow and blood ΔCt values correlated with PFS (P < 0.001; P = 0.001) even when bone marrow was morphologically negative (P = 0.001; P = 0.014). Multivariate analysis showed that bone marrow and blood ΔCt values were associated with PFS independently of clinical disease and MYCN gene status (P < 0.001; P = 0.055).Conclusions: This five-gene NB5 assay for NB-mRNA improves definition of disease status and correlates independently with PFS in relapsed/refractory neuroblastoma.

SUMMARY Introduction: This nonrandomized pilot study assesses the efficacy of a new future- oriented form of therapy, known as future-directed therapy (FDT), as a treatment for pa- tients with Major Depressive Disorder (MDD) in a naturalistic hospital-based outpatient psychiatry clinic. The study measured symptom severity of depression and anxiety, in addi- tion to quality of life pre- and posttreatment. Aims: The study examined a new manualized treatment designed to help people antic- ipate a more positive future. The intervention consists of twenty 90-min group sessions administered twice a week over 10 weeks. The intervention was compared to depressed patients in the same clinic who enrolled in traditional cognitive-based group psychother- apy. Sixteen patients with MDD completed the FDT intervention as part of their outpatient treatment for depression. Seventeen patients with MDD participated in treatment as usual (TAU) cognitive-based group therapy. The Quick Inventory of Depressive Symptoms, the Beck Anxiety Inventory, and the Quality-of-Life Enjoyment and Satisfaction Questionnaire short form, self-report instruments were administered prior to and immediately after the completion of therapy. Results: Patients treated with FDT demonstrated significant improvements in depression (P = 0.001), anxiety (P = 0.021) and quality of life (P = 0.035), and also reported high sat- isfaction with the therapy. Compared to the TAU group, patients treated with FDT showed greater improvements in depressive symptoms (P = 0.049). Conclusions: FDT may have the potential of becoming an additional treatment option for patients with MDD.

10039 Background: Accurate quantification of tumor burden in NBL patients is needed to define homogenous populations for therapy and establish response criteria that predict outcome. The 5-gene TLDA assay was developed for quantification of NBL cells in bone marrow (BM) and blood (BLD). Methods: Expression of CHGA, DCX, DDC, PHOX2B, and TH (NBL genes) was quantified with TLDA and reported as the geometric mean cycle threshold for the 5 genes (DGS=detection gene score; inversely related to tumor content, 40=negative). Sixty-three patients with recurrent/refractory NBL had TLDA performed on 107 BM and 99 BLD samples (66 paired) at 140 time points. Based on central review of reports, tumor longest diameter (LD) on CT/MRI (n=118), and number of 123I-MIBG avid sites (n=120) were recorded. Percentage of tumor cells in BM was from institutional reports of bilateral BM aspirates/biopsies (n=109). Overall response was assessed per NANT Response Criteria. Spearman rank correlation was performed. Results:TLDA detected tumor cells in 62/99(63%) BLD (average DGS=37.45) and 91/107(85%) BM samples (average DGS=33.42). 39/91(42%) with positive BM TLDA were negative by morphology. BLD and BM TLDA were correlated r = 0.6540, p< 0.0001 with stronger correlation with lower BM DGS scores. The BM and BLD DGS correlated with % BM involvement (BM r= -0.63, p
