Literature showed that lymph node ratio (LNR) and total number of lymph nodes (TNODS) are independent prognostic factors in node-positive colon cancer. Our study assesses the prognostic superiority of the log odds of positive lymph nodes (LODDS) in the same patient population. A total of 24,477 stage III colon cancer cases from the SEER registry were(More)
Recent literature has shown that lymph node ratio (LNR) is superior to the number of positive lymph nodes (pLNs) in predicting the prognosis in several malignances other than colon cancer. We hypothesize that LNR may play a similar role in stage III colon cancer. We included 24,477 stage III colon cancer cases from the Surveillance, Epidemiology, and End(More)
BACKGROUND AND OBJECTIVES We operated on three patients with leiomyosarcoma of the inferior vena cava. METHODS Complete excision was possible in all three patients. RESULTS One patient developed widespread metastasis at 23 months, one patient is alive with no evidence of disease at 70 months, and one patient is alive at 15 months. The third patient had(More)
OBJECTIVE To assess whether TNODS is an independent prognostic factor after adjusting for the lymph node ratio (LNR). SUMMARY BACKGROUND DATA The medical literature has suggested that the TNODS is associated with better survival in stage II and III colon cancer. Thus TNODS was endorsed as a quality measure for patient care by American College of Surgeons,(More)
A variety of cytokines play a role in the inflammatory response. Interleukin-6 (IL-6)-type cytokines are released in response to tissue injury or an inflammatory stimulus, and act locally and systemically to generate a variety of physiologic responses. Interleukin-6 concentrations are elevated after surgery, trauma, and critical illness. The magnitude of(More)
Pentoxifylline (Trental) is metabolized by red blood cells and the liver into seven metabolites. Metabolites I and V have significant hemorrheologic effects. They are both similar to pentoxifylline in their activity on red blood cell membrane fluidity. Metabolite I is more active than pentoxifylline in inhibiting ADP-induced platelet aggregation. Metabolite(More)
Thromboembolic disorders are frequent complications in polycythemia vera. In addition to thrombocytosis with hyperaggregability, leukocytosis, and high hematocrit, hyperviscosity syndrome, a new component, is described in the pathophysiology of this phenomenon. There is decreased red cell membrane fluidity with decreased deformability which increases the(More)
Neutropenic enterocolitis (NE) is an unusual complication of neutropenia. Its presentation is dramatic, treatment is controversial, and the outcome may be devastating. The available literature about this entity is mainly case reports and autopsy studies. We have recently performed a celiotomy on a patient who developed sepsis and an acute surgical abdomen(More)
Leucine (LEU) kinetics were assessed using a primed-continuous infusion of L-[1-14C]LEU in normal overnight-fasted male volunteers during a basal period and an experimental period where insulin (INS) was infused at either 0.6, 1.2, 2.5, 5.0, 10, or 20 mU.kg-1.min-1 with euglycemia maintained. Two protocols were used: 1) subjects were allowed to develop(More)
Patients with ulcerative colitis (UC) are at an increased risk for the development of colorectal cancer (CRC). Unlike sporadic CRC, the cancer in UC patients arises from a focal or multifocal dysplastic mucosa in areas of inflammation. The clinical features of UC-associated cancer are similar to those found in patients with hereditary non-polyposis(More)
