Introduction: Acoustic transient cavitation is the primary mechanism of sonochemical reaction and has potential use for tumor treatment. In this study, the in vivo anti-tumor effect of simultaneous dual-frequency ultrasound at low-level intensity (ISATA < 6 W/cm2) was investigated in a spontaneous murine model of breast adenocarcinoma in Balb/c mice. Materials and Methods: Forty tumor bearing m...
Background & Aims: Breast cancer is one of the most prevalent non-skin-related malignancies among women in the world. Thus, many countries have commenced screening test in early stages in order to diagnose breast cancer. Buried object detection is performed in the present work to detect 3-D breast cancer applying SVM classifier. Some transmitters and receivers are located above the breast. E...
BACKGROUND AND PURPOSE Tumor volume and cartilage invasion have been suggested as prognostic factors of glottic carcinomas following definitive radiation therapy. Radiologic examinations provide additional information regarding the deep extension of tumor. We determined whether dynamic helical CT can predict local control of early (T1 and T2 stage) glottic carcinomas treated with definitive rad...
PURPOSE Using current radiobiologic models and biologic parameters, we performed an exploratory study of the clinical consequences of hypofractionation in prostate cancer radiotherapy. METHODS AND MATERIALS Four hypofractionated treatment regimens were compared with standard fractionation of 2 Gy x 39 for prostate carcinoma using a representative set of anatomical structures. The linear-quadr...
PURPOSE To evaluate the roles of preradiotherapy hemoglobin level and microvessel density (MVD) as predictive factors for tumor control and survival in patients with laryngeal cancer treated with primary radiotherapy. EXPERIMENTAL DESIGN Two hundred and fourteen patients with stage I-IV laryngeal cancer were included in the analysis. Patients were treated with once daily fractionated radiothe...
