HYPOTHESIS Focused helical computed tomographic (CT) scanning with rectal contrast only is a superior diagnostic modality compared with the traditional triple-contrast CT scan for the diagnosis of acute appendicitis. DESIGN Prospective randomized analysis of both CT scan modalities. INTERVENTIONS Only patients with uncertain diagnosis of acute appendicitis were entered in the study. The pat...
BACKGROUND The objective of this study was to describe clinicopathologic features, patterns of recurrence, and survival according to breast cancer subtype with a focus on triple-negative tumors. METHODS In total, 15,204 women were evaluated who presented to National Comprehensive Cancer Network centers with stage I through III breast cancer between January 2000 and December 2006. Tumors were ...
triple negative breast cancers (tnbcs) are associated with aggressive course, higher rates of visceral and central nervous system metastases and lower survival rate than hormone receptor positive. once metastasis has occurred, a median survival was approximately one year. currently, chemotherapy in tnbc is similar to other her2- negative breast cancers but in the near future, it will revolution...
BACKGROUND Triple-negative breast cancer, characterized by a lack of hormone receptor and HER2 expression, is associated with a particularly poor prognosis. Focusing on potentially modifiable breast cancer risk factors, we examined the relationship between body size, physical activity, and triple-negative disease risk. METHODS Using data from 155,723 women enrolled in the Women's Health Initi...
BACKGROUND Prognostication of breast cancer using clinico-pathologic variables, although useful, remains imperfect. Recent research has focused on finding new markers of prognosis using gene expression profiling. Panels of proteins assessed by immunohistochemistry might also be useful in this regard. This study focused on Bcl-2 protein expression in triple-negative (TNBC) and non- triple-negati...
