PURPOSE The study was designed to assess the toxicity and activity of high-dose ifosfamide (HDI) administered by continuous infusion at a dose of 4 g/m2/d over 3 days every 4 weeks in adult patients with advanced soft tissue sarcomas (ASTS) pretreated with doxorubicin and/or a standard-dose ifosfamide (SDI)-containing regimen. PATIENTS AND METHODS Between(More)
In an attempt to better understand breast tumors sensitivity or resistance to anticancer drugs, the main drug-metabolizing enzyme systems were evaluated in both breast tumors and their corresponding peritumoral tissues in 12 patients. The following enzymes were assayed by Western blot: cytochromes P-450 (1A1/A2, 2B1/B2, 2C8-10, 2E1, 3A4); glutathione(More)
PURPOSE To determine the value of contrast material-enhanced subtraction magnetic resonance (MR) imaging in assessment of response to chemotherapy in locally advanced breast cancer. MATERIALS AND METHODS Eighteen women treated with chemotherapy because of locally advanced breast cancer underwent preoperative MR examination including both routine and(More)
To better understand the importance of drug-metabolizing enzymes in carcinogenesis and anticancer drug sensitivity of human non-small cell lung cancer, we studied the main drug-metabolizing enzyme systems in both lung tumors and their corresponding nontumoral lung tissues in 12 patients. The following enzymes were assayed by Western blot analysis:(More)
PURPOSE A phase I/II trial of vinorelbine (VRL) administered by continuous infusion (CIV) was conducted in advanced breast carcinoma (ABC) patients to determine the maximum-tolerated dose (MTD) and to evaluate the toxicity pattern and antitumor activity of this alternative administration schedule to the currently recommended weekly short intravenous (IV)(More)
BACKGROUND Head and neck squamous cell carcinomas (HNSCC) present variable aggressiveness and chemosensitivity. Because the glutathione (GSH) system and thymidylate synthase (TS) are involved in the resistance to the main drugs used in HNSCC (cisplatin and 5-FU), we studied these systems in tumors and normal mucosae. METHODS Tumor samples and normal(More)
The combination of two operations seems to have advantages for the patient because it avoids the repetition of surgical intervention. It is indicated, in apparently simple cases consisting of a stable corneal opacity and senile cataract in a normal anterior segment, or on the contrary in complex cases in which the corneal and lens disease has often a common(More)
