Early thymus and activation-regulated chemokine (TARC) reduction and response following panobinostat treatment in patients with relapsed/refractory Hodgkin lymphoma following autologous stem cell transplant.

Abstract In a phase 2 trial of panobinostat in 129 patients with relapsed or refractory Hodgkin lymphoma, exploratory analyses of chemokines and cytokines were prospectively performed in 109 patients to determine their association with clinical outcomes. Patients were categorized into two groups (reductions > median and reductions ≤ median) based on percentage change from baseline of log10 transformed measurements. Thymus and activation-regulated chemokine (TARC) was most strongly associated with clinical outcome.

Relationship between quantitative GRB7 RNA expression and recurrence after adjuvant anthracycline chemotherapy in triple-negative breast cancer.

Purpose: To conduct an exploratory analysis of the relationship between gene expression and recurrence in patients with operable triple-negative breast cancer (TNBC) treated with adjuvant doxorubicin-containing chemotherapy.

Experimental Design: RNA was extracted from archived tumor samples derived from 246 patients with stage I-III TNBC treated with adjuvant doxorubicin-containing chemotherapy, and was analyzed by quantitative reverse transcriptase PCR for a panel of 374 genes. The relationship between gene expression and recurrence was evaluated using weighted Cox proportional hazards model score tests.

Physician survey of the effect of the 21-gene recurrence score assay results on treatment recommendations for patients with lymph node-positive, estrogen receptor-positive breast cancer.

Purpose: To survey the effect of the 21-gene recurrence score (RS) assay results on adjuvant treatment recommendations for patients with lymph node-positive (N+), estrogen receptor-positive (ER+) breast cancer.

Methods: Medical oncologists who ordered the 21-gene RS assay were invited to complete a survey regarding their most recent patient with N+/ER+ breast cancer. We obtained responses from 160 (16%) of the 1,017 medical oncologists.

Associations of the correlates of protection and implication on the statistical power for demonstrating non-inferiority: application of a re-sampling method on a large phase III influenza vaccine clinical trial.

Background: In the later stage of the clinical development of new vaccines it is required to demonstrate their efficacy with the immunogenicity measures established as correlates for disease protection. Evaluation of interpandemic trivalent influenza vaccines is commonly assessed by three immunogenicity measures for each strain in different age groups: Seroprotection, Seroconversion and Geometric Mean Titers. US and European guidelines with respect to this topic have been issued for the licensure of new influenza vaccines.
