Accumulating evidence suggests that characteristics of pre-treatment FDG-PET could be used as prognostic factors to predict outcomes in different cancer sites. Current risk analyses are limited to visual assessment or direct uptake value measurements. We are investigating intensity-volume histogram metrics and shape and texture features extracted from PET(More)
PURPOSE This study aimed to assess the association between pretreatment c-Met overexpression in local-regional advanced cervical cancer patients treated definitively with concurrent chemoradiation therapy (CRT) and treatment outcomes including overall survival (OS), progression-free survival (PFS), distant metastases (DM) control, and local-regional control(More)
To more accurately and precisely delineate a tumor in a 3D PET image, we proposed a novel, semi-automatic, two-stage method by utilizing an adaptive region-growing algorithm and a dual-front active contour model. First, a rough region of interest (ROI) is manually drawn by a radiation oncologist that encloses a tumor. The voxel having the highest intensity(More)
PURPOSE To quantify the amount of free-breathing motion measured using Four-dimensional (4D) CT scans of mediastinal and hilar lymph nodes and to compare this motion to the primary lung tumor motion. METHODS AND MATERIALS Twenty patients with primary lung cancer, radiographically positive lymph nodes, and prior 4D CT scans were retrospectively analyzed.(More)
Single-dose intraoperative radiotherapy (IORT) is an emerging treatment for women with early stage breast cancer. The objective of this study was to define the frequency of IORT use, patient selection, and outcomes of patients treated in North America. A multi-institutional retrospective registry was created, and 19 institutions using low-kilovoltage IORT(More)
PURPOSE The optimal dosimetric parameters and planning techniques for high-dose-rate vaginal brachytherapy (HDR-VB) are unclear. Our aim was to evaluate the utility of bladder and rectal dosimetry for patients receiving HDR-VB for postoperative treatment of endometrial carcinoma. MATERIAL AND METHODS Patients with endometrial cancer who underwent(More)
PURPOSE To determine the factors that correlate with cylinder size in vaginal brachytherapy (VB) after hysterectomy for endometrial carcinoma. METHODS AND MATERIALS Patients treated for endometrial cancer from January 1, 2003 to December 31, 2013 were reviewed from a single institution. Patients included underwent total abdominal hysterectomy with(More)
OBJECTIVE We reviewed data on treatment of stage IB1 cervical cancer at our institution to compare recurrence, complications, and survival of women treated primarily by radical hysterectomy versus radiation. METHODS Records for women treated for stage IB1 cervical cancer between January 1, 1990 and June 1, 2010 were retrospectively reviewed. Recurrence,(More)
It is postulated that the outcomes in treating breast cancer with intraoperative radiotherapy (IORT) would be affected by the residual cancer cell distribution within the tumor bed. The three-dimensional (3D) radiation doses of IntrabeamTM (IB) IORT with a 4-cm spherical applicator at the energy of 50 and 40 kV were calculated. The modified linear quadratic(More)
