A Multicenter Pilot Evaluation of the National Institutes of Health Chronic Graft-versus-Host Disease (cGVHD) Therapeutic Response Measures: Feasibility, Interrater Reliability, and Minimum Detectable Change

The lack of standardized criteria for measuring therapeutic response is a major obstacle to the development of new therapeutic agents for chronic graft-versus-host disease (cGVHD). National Institutes of Health (NIH) consensus criteria for evaluating therapeutic response were published in 2006. We report the results of four consecutive pilot trials evaluating the feasibility and estimating the inter-rater reliability and minimum detectable change of these response criteria

Enhancing Self-care Among Oral Cancer Survivors: Protocol for the Empowered Survivor Trial

BackgroundSurvivors of oral cavity and oropharyngeal cancer frequently experience difficulties in swallowing; tasting; speaking; chewing; and maintaining comfortable movements of the head, neck, and shoulder. Engagement in regular self-care can reduce further loss of function and mitigate late effects. Despite the substantial self-care requirements, there are no empirically based interventions to enhance the skills and confidence of these survivors in managing their ongoing care. ObjectiveThe aim of this study is to describe the rationale and methodology for a randomized controlled trial evaluating Empowered Survivor (ES) versus Springboard Beyond Cancer, a general web-based program for cancer survivors, on self-efficacy in managing care, preparedness for managing survivorship, and health-related quality of life (QOL). MethodsThis study will recruit a total of 600 individuals who were diagnosed with oral cavity or oropharyngeal cancer in the past 3 years and are currently cancer free primarily from state cancer registries; these individuals will be randomly assigned to either the ES or Springboard Beyond Cancer condition. The participants complete measures of self-efficacy in managing care, preparedness for survivorship, health-related QOL, and engagement in oral self-examination and head and neck strengthening and flexibility exercises at baseline and 2 and 6 months after baseline. The primary aim of this study is to evaluate the impact of ES versus Springboard Beyond Cancer on self-efficacy, preparedness, and health-related QOL. The secondary aim is to examine the mediators and moderators of ES’s impact on self-efficacy in managing care, preparedness, and health-related QOL at 6 months. The exploratory aim is to conduct a process evaluation of ES to identify potential oncology or community settings for future implementation. ResultsMultilevel modeling will be used to examine whether there are significant differences between the ES and Springboard Beyond Cancer interventions over time. Mediational models will evaluate the indirect effects of ES on outcomes. Quantitative analyses will evaluate the predictors of ES use, and qualitative analyses will evaluate the preferred timing and settings for the implementation of ES. ConclusionsThis randomized controlled trial evaluates a completely web-based intervention, ES, versus a general web-based program for cancer survivors, Springboard Beyond Cancer, on self-efficacy in managing care, preparedness for managing survivorship, and health-related QOL and identifies the putative mediators and moderators of the intervention’s effects. If an effect on the primary outcomes is illustrated, the next step could be an implementation trial to evaluate the intervention’s uptake in and impact on an oncology care setting or nonprofit organizations.

Increased T-bet+ cytotoxic effectors and type I interferon–mediated processes in chronic graft-versus-host disease of the oral mucosa

Although chronic graft-versus-host disease (cGVHD) is a major long-term complication of allogeneic hematopoietic stem cell transplantation, little is known of its pathogenesis. We have systematically examined oral mucosa among cGVHD patients and determined that the clinical severity of oral cGVHD was correlated with apoptotic epithelial cells, often found adjacent to infiltrating effector-memory T cells expressing markers of cytotoxicity and type I cytokine polarization. Accumulation of T-bet+ T-cell effectors was associated with both increased proliferation and the expression of the type I chemokine receptor CXCR3. Concurrently, in both infiltrating cells and keratinocytes, we observed increased expression of the CXCR3 ligand MIG (CXCL9) and interleukin-15 (IL-15), type I interferon (IFN)–inducible factors that support the migration, type I differentiation, and expansion of alloreactive effectors. In severely affected mucosa, we observed high levels of MxA, a protein specifically induced by type I IFN, and signal transducer and activator of transcription 1 (STAT1) phosphorylation, a critical step in the IFN-signaling pathway, along with increased numbers of plasmacytoid dendritic cells. These data challenge the current paradigm of cGVHD as a type II cytokine–driven disorder and support the model that oral cGVHD results from type I IFN–driven immigration, proliferation, and differentiation of T-bet+ type I T effectors.
