前列腺癌患者治疗计划的解决方案:优越的体积调制电弧
Inverse planning is at the heart of prostate Volumetric Modulated Arc Therapy (VMAT) treatment procedure and critically determines its level of success. As practiced now, the capacity of VMAT is greatly underutilized because of inferior computing performance of existing optimization methods. An alternative mathematical approach that improves both the efficiency and the efficacy is needed and is the center of this research. We propose to develop a new innovative inverse planning tool, based on the novel idea of superiorization, to replace the classical constrained optimization approaches employed in clinics today for prostate VMAT cases. Year 1 of the training award focused on formulating the VMAT problem as a constrained superiorization problem and on the development of a framework of fast converging inverse planning algorithms. Empty solution sets and infeasibility constraints that often exist in real-world applications were incorporated into the model. The new framework was proven mathematically and its efficacy was demonstrated when it was compared to a classical optimization method. The superiorization methodology was Implemented, tested and evaluated on a previously treated prostate case where good initial results were obtained.

寻找乳腺癌基因融合/易位
Previously, we completed the molecular/ biochemical characterization of several shortlisted candidate gene fusions from the transcriptome sequencing of over 70 previously validated samples. From these studies, we identified two rare but recurrent gene fusions in breast cancer cell lines and tissues involving the MAST and Notch genes. Both of these fusion genes are potentially targetable and patients harboring MAST or Notch fusions may benefit from MAST or Notch inhibitors. We also describe a novel study of cancer-specific pseudogenes, including those in breast cancer. Most recently, through our clinical sequencing initiative, we discovered a series of activating mutations in the estrogen receptor (ESR1) in breast cancer patients. These activating mutations in ESR1 are a key mechanism in acquired endocrine resistance in breast cancer therapy. Overall, these discoveries made over the funding period contribute towards the understanding of the molecular and genetic etiology of breast cancer that will advance the development of targeted therapies.

防御自动化神经行为学评估(DANA)过渡到操作使用
This grant prepares DANA (Defense Automated Neurobehavioral Assessment), the next-generation neurocognitive assessment tool (NCAT), for transition into operational military use. DANA is a clinical decision support tool developed for and funded by the Department of Defense (DOD) for use in field and clinical settings. The effort is organized around two foci science and transition. The science concentrates on CONUS-based studies such as testing DANA in clinical drug, fatigue/alertness, concussion and/or depression protocols. The second thrust, transition, includes obtaining FDA clearance for DANA (DOD has determined it is a medical device), and positioning DANA to be operationally deployed into the military.
