Determination of HER-2/neu overexpression and clinical predictors of survival in a cohort of 347 patients with primary malignant brain tumors.

Introduction: HER-2/neu overexpression has been associated with poor prognosis in a variety of malignancies. The extent and relevance of HER-2/neu overexpression in human central nervous system (CNS) malignancies is unclear. We retrospectively analyzed a large cohort of patients with primary malignant brain tumors to evaluate the role of HER-2/neu overexpression, clinical characteristics at presentation, and other predisposing factors as predictors of survival.

Angiosarcoma of the small intestine: a possible role for thalidomide?

An 85-yr-old male presented with complaints of a 40-lb weight loss and a dull left upper quadrant abdominal pain. He also complained of decreased appetite, generalized weakness, generally not feeling well, and a dull left upper quadrant abdominal pain that was not relieved by food. He had a ventral and a left-sided inguinal hernia.

Role of Her-2/neu overexpression and clinical determinants of early mortality in glioblastoma multiforme.

Her-2/neu or c-erbB-2, a 185-kD protein is an important prognostic indicator/target for therapy in metastatic breast carcinoma. Recent reports have also identified a role for Her-2/neu overexpression in other solid tumors. We performed a retrospective analysis to evaluate the prevalence and prognostic role of Her-2/neu overexpression in patients with glioblastoma multiforme (GBM).

Effect of low-molecular-weight heparin on potassium homeostasis.

Background: Low-molecular-weight heparins (LMWHs) are being preferred to unfractionated heparin (UFH) because of their superior convenience and a comparable or slightly better toxicity profile. Whether LMWH has an inhibitory effect on aldosterone that causes hyperkalemia is yet uncertain.

Methods: Twenty-eight patients (all male; mean age: 70 years, range 52-87 years) placed on LMWH therapy (40 mg subcutaneously every 12 h) for deep venous thrombosis prophylaxis after an operation were included in the study.

An epidemiological study evaluating the relationship of distance from a tertiary care cancer center to early detection of colorectal carcinoma.

Objective: AJCC stage at diagnosis determines the treatment approach and indirectly predicts outcome in patients with colorectal carcinoma. The purpose of our study was to investigate whether there was a delay in diagnosis leading to a more advanced stage at diagnosis (which affects outcome) of patients with colorectal cancers because of distance from a referral center, after positive fecal occult blood testing (FOBT).

Design: Our retrospective observational study involved all cases of colonic and rectosigmoid cancers that were referred for an endoscopic procedure after an initial positive FOBT done as a part of routine screening in asymptomatic patients.

Identification and relationship of HER-2/neu overexpression to short-term mortality in primary malignant brain tumors.

Introduction: HER-2/neu overexpression has been associated with poor prognosis in solid tumors. The extent to which HER-2/neu is overexpressed in human central nervous system malignancies is unclear. We retrospectively analyzed a large cohort of patients with primary brain tumors to evaluate the prognostic role of HER-2/neu overexpression and clinical characteristics at presentation in patients with shortened survival (< 6 months).

Role of immunohistochemical identification of Her-2/neu and detection of variability in overexpression in pancreatic carcinoma.

Introduction: Her-2/neu overexpression has been recently shown to be a poor prognostic factor in breast carcinoma. Overexpression has also been demonstrated in adenocarcinoma of the pancreas but the significance is unclear. We attempted to study the role of Her-2/neu overexpression, detected by immunohistochemistry, in pancreatic carcinoma and also examined for variability of overexpression across different tissue sections on individual tumor specimen.
