BACKGROUND Previous studies have shown an increasing incidence of small bowel tumors in the United States. Our objective was to assess this increase by examining changes in histology-specific incidence, treatment, and survival. METHODS Patients with small bowel malignancies were identified from the National Cancer Data Base (NCDB, 1985-2005) and the(More)
The National Cancer Data Base (NCDB) is a nationwide oncology outcomes database that currently collects information on approximately 70% of all new invasive cancer diagnoses in the United States each year and serves as a powerful clinical surveillance and quality improvement mechanism for cancer programs participating in the American College of Surgeons(More)
IMPORTANCE Financial penalties for readmission have been expanded beyond medical conditions to include surgical procedures. Hospitals are working to reduce readmissions; however, little is known about the reasons for surgical readmission. OBJECTIVE To characterize the reasons, timing, and factors associated with unplanned postoperative readmissions. (More)
BACKGROUND The extent of surgery for papillary thyroid cancers (PTC) remains controversial. Consensus guidelines have recommended total thyroidectomy for PTC > or =1 cm; however, no study has supported this recommendation based on a survival advantage. The objective of this study was to examine whether the extent of surgery affects outcomes for PTC and to(More)
BACKGROUND With the development of stage-specific treatments for pancreatic cancer, controversies exist concerning optimal clinical and pathologic staging. The most recent edition of the American Joint Committee on Cancer (AJCC) Cancer Staging Manual 6(th) Edition included some notable modifications. In anticipation of the 7(th) edition's publication, the(More)
BACKGROUND Despite studies demonstrating improved outcomes, pessimism persists regarding the effectiveness of surgery for pancreatic cancer. Our objective was to evaluate utilization of surgery in early stage disease and identify factors predicting failure to undergo surgery. METHODS Using the National Cancer Data Base (1995-2004), 9559 patients were(More)
Multiple endocrine neoplasia type 1 is an autosomal dominant tumor syndrome. Manifestations include neoplasms of the parathyroid glands, enteropancreatic neuroendocrine cells, and the anterior pituitary gland. The MEN1 tumor suppressor gene encodes menin, a 610 amino acid nuclear protein without sequence homology to other proteins. To elucidate menin(More)
PURPOSE For women with breast cancer, the role of completion axillary lymph node dissection (ALND) after identification of nodal metastases by sentinel lymph node biopsy (SLNB) has been questioned. Our objectives were to assess national nodal evaluation practice patterns and to examine differences in recurrence and survival for SLNB alone versus SLNB with(More)
BACKGROUND Adrenocortical carcinoma (ACC) is a rare tumor with a relatively poor prognosis. The authors' objectives were to examine treatment utilization and factors associated with long-term survival after resection of ACC in a large, national, patient population. METHODS Patients diagnosed with ACC from 1985 to 2005 were identified from the National(More)
This paper analyzes two intersecting flows of aircraft that must avoid each other, utilizing maneuvers modeled by instantaneous heading changes. Sufficient conditions are derived for stable conflict avoidance, whereby one aircraft's conflict-avoidance action does not generate cascaded diverging conflict-avoidance behavior (known as the domino effect) in(More)
