PURPOSE The prognostic value of the epidermal growth factor receptor (EGFR) in breast cancer and more specifically, in patients with locoregionally advanced disease, is still undefined. We hypothesized that EGFR status plays a major prognostic role in this setting, through expression, activation, or the presence of its mutated variant EGFRvIII. PATIENTS(More)
In this retrospective histologic study, galectin-3 had a sensitivity of 92% (22/24) for papillary thyroid carcinoma and 44% (4/9) for follicular thyroid carcinoma. Thyroid peroxidase (TPO) had a sensitivity of 50% (12/24) for papillary and 11% (1/11) for follicular carcinoma. The combination of galectin-3 and TPO had a sensitivity of 96% (23/24) for(More)
Insulin is a mild mitogen and has been shown to potentiate mitogenic influence of other growth factors. Because hyperinsulinemia and/or overexpression of insulin receptors have been linked to development, progression, and outcome of breast cancer, we attempted to evaluate the mechanism of these associations. We have compared the expression of insulin(More)
Metastatic cancer to the thyroid gland is uncommon. In this report we describe a patient with a malignant fibrous histiocytoma that metastasized to the thyroid, possibly to a preexisting thyroid nodule. A review of the literature reveals that breast and lung carcinoma are the most frequently identified sources of secondary thyroid carcinoma found at(More)
Thyroid nodules are found in 5% to 10% of the population. While these nodules carry only a 5% to 10% risk of malignancy, tests that complement fine-needle aspiration (FNA) cytology in preoperative diagnosis and risk stratification are lacking. Telomerase is a ribonucleoprotein polymerase with activity found in many malignant tissues, but absent from most(More)
BACKGROUND & AIMS It is not clear exactly how many passes are required to determine whether pancreatic masses are malignant using endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA). We aimed to define the per-pass diagnostic yield of EUS-FNA for establishing the malignancy of a pancreatic mass, and identify factors associated with detection of(More)
A young woman presented with rapidly progressive dyspnea and clinical findings strongly suggestive of primary pulmonary hypertension or possible pulmonary embolism (or both). She died of acute right-sided heart failure. A diagnosis of pulmonary veno-occlusive disease was made at autopsy. Approximately 100 cases of this disease have been reported previously(More)
PURPOSE To study prognostic factors after high-dose chemotherapy (HDC) for patients with stage IV oligometastatic breast cancer. PATIENTS AND METHODS Sixty patients with minimal metastatic disease amenable to local therapy enrolled onto a prospective HDC trial were analyzed for potential prognostic factors. Tumor blocks were retrospectively collected from(More)
PURPOSE We described previously a prognostic model for high-risk primary breast cancer patients receiving high-dose chemotherapy (HDC). Such model included nodal ratio (no. involved nodes:no. dissected nodes), tumor size, hormone receptors, and HER2. In the present study we intended to test this model prospectively in a second patient cohort. In addition,(More)
Telomerase is a ribonucleoprotein enzyme that synthesizes telomeric DNA onto the ends of chromosomes, thereby preventing the replication-dependent shortening of these ends. Telomerase activity is detected in a wide range of cancers of various tissues, and its expression may be a critical step in tumor progression. The telomeric repeat amplification protocol(More)
