Using permanent-section immunohistochemistry, we investigated the role of HER-2/neu in the development and progression of human breast cancer by measuring its overexpression in a series of hyperplastic (n = 30), dysplastic (n = 15), and malignant neoplastic (n = 708) lesions of ductal epithelium and by evaluating the relationships between overexpression and(More)
PURPOSE Amplification and/or overexpression of the HER-2/neu oncogene have been shown to correlate with poor clinical outcome in patients with axillary node-positive breast cancer. In contrast, the prognostic significance of HER-2/neu in node-negative disease is controversial. This study was undertaken to evaluate further the relationship between HER-2/neu(More)
We randomly assigned 536 women who had undergone either a modified radical mastectomy or a total mastectomy with low axillary-node dissection for potentially curable breast carcinoma to receive adjuvant chemotherapy or no-treatment observation. The patients were considered at high risk for recurrence because they had either an estrogen-receptor-negative(More)
PURPOSE The identification of a subset of patients with axillary lymph node-positive breast cancer with an improved prognosis would be clinically useful. We report the prognostic importance of histologic grading and proliferative activity in a cohort of patients with axillary lymph node-positive breast cancer and compare these parameters with other(More)
The current trial was designed to assess whether the addition of prednisone or prednisone + tamoxifen would enhance the therapeutic effectiveness of 1 year of adjuvant CMF therapy. Premenopausal women with ipsilateral axillary node-positive breast carcinoma and known estrogen receptor (ER) status were randomized to receive 1 year of postoperative treatment(More)
BACKGROUND The purpose of this study was to test the role of radiotherapy following total mastectomy, axillary dissection, and adjuvant systemic therapy in the management of operable locally advanced breast carcinoma. METHODS After undergoing mastectomy and axillary dissection, 426 patients with locally advanced breast carcinoma were registered on study(More)
Metastatic Leydig cell carcinomas account for less than 0.2% of all testicular cancers, and may be associated with sex hormone production. Leydig cell carcinoma is relatively refractory to radiotherapy and chemotherapy, and median survival of patients with metastatic disease is less than 2 years. Presented are three cases of metastatic Leydig cell cancer,(More)
The Monte Carlo-based inverse model of diffuse reflectance described in part I of this pair of companion papers was applied to the diffuse reflectance spectra of a set of 17 malignant and 24 normal-benign ex vivo human breast tissue samples. This model allows extraction of physically meaningful tissue parameters, which include the concentration of absorbers(More)
Nonmalignant (n = 36) and malignant (n = 20) tissue samples were obtained from breast cancer and breast reduction surgeries. These tissues were characterized using multiple excitation wavelength fluorescence spectroscopy and diffuse reflectance spectroscopy in the ultraviolet-visible wavelength range, immediately after excision. Spectra were then analyzed(More)
The term sulcus vocalis has been applied to a spectrum of disorders ranging from minor vocal fold indentations to destructive lesions causing severe dysphonia. To clarify the pathophysiology and to develop a more rational approach to treatment, we report a series of sulcus patients including 20 surgical cases. Clinical and histopathologic analysis produced(More)
