PURPOSE We have previously reported that matrix metalloproteinases MMP-2, MMP-9, and the complex MMP-9/NGAL can be detected in urine of patients with a variety of cancers including prostate and bladder carcinoma. In addition, we also detected several unidentified urinary gelatinase activities with molecular weights >125 kDa. The objective of the current(More)
Matrix metalloproteinases (MMPs) have been implicated in mechanisms of metastasis in experimental cancer models and in human malignancies. In this study, we used substrate gel electrophoresis (zymography) to determine the frequency of detection of MMPs in urine of patients with a variety of cancers. Three molecular weight classes of urinary MMPs, Mr 72,000,(More)
PURPOSE To evaluate the toxicity and efficacy of a 4-day regimen of docetaxel, cisplatin, fluorouracil, and leucovorin (TPFL4) in patients with locoregionally advanced squamous cell carcinoma of the head and neck (SCCHN). PATIENTS AND METHODS Thirty previously untreated patients with stage III or IV SCCHN and Eastern Cooperative Oncology Group functional(More)
BACKGROUND The authors conducted a Phase I/II study in patients with a poor prognosis who had locally advanced squamous cell carcinoma of the head and neck (SCCHN) and who were treated initially with induction chemotherapy. Patients were treated with weekly docetaxel and concurrent daily fractionated radiation therapy to determine the maximum tolerated dose(More)
Regulated shedding of cell surface proteins is a mechanism for rapid activation of autocrine and paracrine signaling. Here we report that chelerythrine, a protein kinase C (PKC) inhibitor that possesses a variety of biological functions, is a potent inducer of heparin-binding epidermal growth factor-like growth factor (HB-EGF) shedding from the cell(More)
We performed a retrospective review of 65 patients with nonmetastatic clinical inflammatory breast carcinoma treated with radical radiotherapy as the sole local treatment between 1968 and 1986. Chemotherapy was given to 47 patients (72%). The median total radiation dose to the target volume was 6,984 cGy. With a median follow-up in survivors of 41 months,(More)
PURPOSE On the basis of our anecdotal clinical observations that nonsteroidal anti-inflammatory agents relieved dysuria during radiotherapy for patients with prostate cancer, we conducted a Phase III randomized trial of ibuprofen vs. placebo for patients who had an increase in acute urinary symptoms. Our in vitro and in vivo laboratory data with a higher(More)
Matrix metalloproteinases (MMP) and a disintegrin and metalloprotease 12 (ADAM 12) can be detected in the urine of breast cancer patients and provide independent prediction of disease status. To evaluate the potential of urinary metalloproteinases as biomarkers to predict breast cancer risk status, urine samples from women with known risk marker lesions,(More)
Interaction of a transformed rat prostate epithelial cell (NbMC-2) with basement membrane gels (Matrigel) has been evaluated using a long-term matrix culture system. NbMC-2 cells, and single-cell clonal derivatives, formed spheroidal multicellular structures (aggregates) on Matrigel surfaces and were weakly invasive or noninvasive during a 1 week period.(More)
PURPOSE Many authors have studied the problems associated with the three-field breast treatment, yet the proposed solutions present their own difficulties. This study presents a technique that overcomes these difficulties, reduces scatter to the contralateral breast, and improves setup reproducibility. METHODS AND MATERIALS Patients are set up with both(More)
