Purpose:
Recent reports of medical errors in radiaKon treatment delivery have emphasized the importance of quality assurance (QA) pracKces. Strict guidelines exist for medical physics QA, but not for QA procedures as applied to clinicians. We sought to document how clinical quality assurance (QA) meeKngs or “chart rounds” are performed across academic North American RadiaKon Oncology departments.

BACKGROUND: The p53 protein family coordinates stress responses of cells and organisms. Alternative promoter usage and/or splicing of p53 mRNA gives rise to at least nine mammalian p53 proteins with distinct N- and C-termini which are differentially expressed in normal and malignant cells. The human N-terminal p53 variants contain either the full-length (FL), or a truncated (ΔN/Δ40) or no transactivation domain (Δ133) altogether. The functional consequences of coexpression of the different p53 isoforms are poorly defined. Here we investigated functional aspects of the zebrafish ΔNp53 ortholog in the context of FLp53 and the zebrafish Δ133p53 ortholog (Δ113p53) coexpressed in the …

“For many patients, controlling neurological symptoms, preventing cognitive dysfunction and maintaining functional independence are just as important as prolonging survival.”

While hepatic arterial chemoembolization is efficacious for a number of malignancies, there is scant data regarding treatment of pancreatic adenocarcinoma. We report a complete radiographic response at one year from diagnosis of metastatic pancreatic carcinoma. Gemcitabine/cisplatin based chemoembolization may be of potential benefit for patients with liver-dominant metastases from pancreatic carcinoma. Given the typical survival of 6 months or less in this patient group with standard therapies, further research is warranted.

Splenic Infarction: An Update On William Osler's Observations., Yaacov R Lawrence, Ma Mbbs Mrcp, Russell Pokroy, Mb Bch, Daniel Berlowitz, Mb Bch, Dvora Aharoni, Md, Daniel Hain, Md, Gabriel S Breuer, Md

BACKGROUND: Osler taught that splenic infarction presents with left upper abdominal quadrant pain, tenderness and swelling accompanied by a peritoneal friction rub. Splenic infarction is classically associated with bacterial endocarditis and sickle cell disease.
OBJECTIVES: To describe the contemporary experience of splenic infarction.
METHODS: We conducted a chart review of inpatients diagnosed with splenic infarction in a Jerusalem hospital between 1990 and 2003.
RESULTS: We identified 26 cases with a mean age of 52 years. Common causes were hematologic malignancy (six cases) and intracardiac thrombus (five cases). Only three cases were associated with bacterial endocarditis. In 21 cases the splenic …

RATIONALE AND OBJECTIVES: The aim of this study was to apply a decision analytic model for the evaluation of coronary artery disease (CAD) to define the optimal utilization of coronary computed tomographic angiography (cCTA) and stress testing.
MATERIALS AND METHODS: The model tested in this study assumes that CAD is evaluated with a stress test and/or cCTA and that a patient with positive evaluation results undergoes cardiac catheterization. On the basis of values of sensitivity, specificity, and radiation dose from the published literature and test costs from the Medicare fee schedule, a decision tree model was constructed as a function …
Ureteroscopic Laser Treatment Of Upper Urinary Tract Neoplasms., Demetrius H. Bagley, Michael Grasso
Ureteroscopic Laser Treatment Of Upper Urinary Tract Neoplasms., Demetrius H. Bagley, Michael Grasso
Department of Radiology Faculty Papers
BACKGROUND: Endoscopic management of upper urinary tract transitional cell carcinoma has assumed an important role in diagnosis and treatment. The introduction of small diameter rigid and flexible ureteroscopes has permitted access to the upper tract. Biopsy techniques have been developed for accurate diagnosis, and the addition of lasers has given the urologists an excellent tool for treatment. METHODS: Medical literature available relative to the endoscopic laser treatment of upper tract neoplasms has been reviewed. RESULTS: Ureteroscopic treatment has been characterized by good success with high recurrence rates, both in the upper tract and in the bladder. Bladder recurrence rates are …

OBJECTIVE. To retrospectively evaluate interobserver agreement for 4 manually determined linear hepatic measurements on magnetic resonance imaging (MRI) and correlation of these linear measurements with hepatic volume.
MATERIALS AND METHODS. Hepatic linear measurements: midhepatic point craniocaudad (MHP CC), maximum CC to liver tip (Max CC), maximum transverse and MHP anteroposterior (AP) dimensions were performed on 116 patients without liver disease who had 1.5 T MR imaging of the abdomen.Linear measurements: MHP CC, Max CC, maximum transverse, MHP AP dimensions and products of CC with MHP AP dimension were correlated with hepatic volumes. Correlation analysis (Pearson product moment correlation), Student t …

Uterine artery embolization (UAE) is an effective treatment for symptomaticuterine fibroids. Magnetic resonance (MR) imaging is typically employed to evaluate the uterus following UAE for fibroid infarction, size, location change, persistent enhancement, changes in adenomyosis and uterine necrosis. Variable pattern of calcification on computed tomography (CT) can differentiate embolic particles and fibroid involution. CT following UAE may be requested because of acute pelvic pain or chest discomfort or pyrexia and/or for complications that may require treatment in acute phase. Visualization of gas in uterus and uterine vessels following UAE is an expected finding that should not be misinterpreted as a …

INTRODUCTION: Despite the great strides made in imaging breast cancer (BC) in humans, the current imaging modalities miss up to 30% of BC, do not distinguish malignant lesions from benign ones, and require histologic examinations for which invasive biopsy must be performed. Annually in the United States, approximately 5.6 million biopsies find benign lesions. More than 50% of human BCs overexpress cyclin D1, and all BCs exhibit VPAC1 oncogene products. Together, these gene products may provide an excellent biomarker for the early and accurate detection of BC. We have evaluated 4 biologically active peptide analogs that have high affinity for …

BACKGROUND: To evaluate and compare the biological impact on different proposed margin recipes for the same geometric uncertainties for intra-hepatic tumors with different tumor cell types or clinical stages. METHOD: Three different margin recipes based on tumor motion were applied to sixteen IMRT plans with a total of twenty two intra-hepatic tumors. One recipe used the full amplitude of motion measured from patients to generate margins. A second used 70% of the full amplitude of motion, while the third had no margin for motion. The biological effects of geometric uncertainty in these three situations were evaluated with Equivalent Uniform Doses …
