  • the Absolute Volume of pet defined active bone marrow spared predicts for high grade hematologic toxicity in cervical cancer patients undergoing chemoradiation
    Clinical & Translational Oncology, 2018
    Co-Authors: Y M Zhou, Christopher Freese, Teresa Meier, Karishma Khullar, Mickaela Sudhoff, M Lamba, Jordan Kharofa

    Abstract:

    Hematologic toxicity (HT) in cervical cancer patients can cause treatment delays and reduction in chemotherapy, especially in high risk patients. Dose to PET-defined regions of active bone marrow (ABM) has been shown to correlate with cytopenias. An Absolute Volume of ABM spared may accurately represent hematopoietic reserve and risk of HT. This analysis evaluates whether the Volume of ABM spared can more accurately predict HT compared to conventional dosimetric parameters. Thirty-one patients treated for cervical cancer with chemoradiation from 9/2011 to 8/2016 were retrospectively reviewed. Receiver operating characteristic (ROC) curve were used to assess optimal cutpoint criterions for grade 3+ HT based on the CTCAEv4. Conventional dosimetric parameters to PBM and ABM (mean dose, V10, V20, V40) were assessed as well as the Absolute Volume (cc) of PBM and ABM spared 10, 20, and 40 Gy. The Absolute Volume of PBM spared 10 Gy (  738 cc of ABM spared 40 Gy (p   738 cc) may be a stronger predictor of HT than conventional dosimetric parameters. This should be further evaluated for clinical use.

  • ab initio all electron calculation of Absolute Volume deformation potentials of iv iv iii v and ii vi semiconductors the chemical trends
    Physical Review B, 2006
    Co-Authors: Yonghua Li, X G Gong

    Abstract:

    We calculate systematically the Absolute Volume deformation potential AVDP of the 8v valence band maximum VBM and the 6c conduction band minimum CBM states for all group IV, III-V, and II-VI semiconductors. Unlike previous calculations that involve various assumptions, the AVDPs are calculated using a recently developed approach that is independent of the selection of the reference energy levels. We find that although the Volume deformation potentials of the CBM state are usually large and always negative, those of the VBM state are usually small and always positive. The AVDP of the VBM state decreases as the p-d coupling increases, e.g., in the II-VI compounds. The AVDP of CBM decreases as the ionicity increases. Our calculated chemical trends of the AVDPs are explained in terms of the atomic orbital energy levels and coupling between these orbitals.
