In vivo visualization of abdominal malignancies with acoustic radiation force elastography.
(Phys Med Biol, 2008-01-07)
The utility of acoustic radiation force impulse (ARFI) imaging for real-time visualization of abdominal malignancies was investigated. Nine patients presenting with suspicious masses in the liver (n = 7) or kidney (n = 2) ...
Reported lifetime aberrant drug-taking behaviors are predictive of current substance use and mental health problems in primary care patients.
(Pain Med, 2008-11)
BACKGROUND: The aim of this report is to determine the frequency of aberrant drug behaviors and their relationship to substance abuse disorders in a large primary sample of patients receiving opioids for chronic pain. METHODS: ...
Comorbidity, age, race and stage at diagnosis in colorectal cancer: a retrospective, parallel analysis of two health systems.
(BMC Cancer, 2008-11-25)
BACKGROUND: Stage at diagnosis plays a significant role in colorectal cancer (CRC) survival. Understanding which factors contribute to a more advanced stage at diagnosis is vital to improving overall survival. Comorbidity, ...
In vivo guidance and assessment of liver radio-frequency ablation with acoustic radiation force elastography.
(Ultrasound Med Biol, 2008-10)
The initial results from clinical trials investigating the utility of acoustic radiation force impulse (ARFI) imaging for use with radio-frequency ablation (RFA) procedures in the liver are presented. To date, data have ...
Age-specific differences in oncogenic pathway deregulation seen in human breast tumors.
(PLoS One, 2008-01-02)
PURPOSE: To define the biology driving the aggressive nature of breast cancer arising in young women. EXPERIMENTAL DESIGN: Among 784 patients with early stage breast cancer, using prospectively-defined, age-specific cohorts ...
The investigation on the location effect of external markers in respiratory-gated radiotherapy.
(Journal of applied clinical medical physics, 2008-04-16)
