Diarrhea is a well-recognized side effect of chemotherapy, which affects the quality of life and when refractory is potentially life threatening. Irinotecan (CPT-11) is associated with an elevated incidence of chemotherapy-induced diarrhea and subsequent morbidity. Standard antidiarrheal treatment is based on high-dose loperamide, but this agent is(More)
A phase II study of flutamide was conducted in 24 patients with stage III and IV ovarian cancer who failed chemotherapy and who had measurable disease. Flutamide was administered at a dose of 100 mg three times daily continuously until evidence of progression. Partial response observed in 1 of the 23 evaluable patients (4.3%) lasted 3 months. Two patients(More)
PURPOSE The aim of this study is to compare various time schedules of granulocyte colony-stimulating factor (G-CSF) treatment in a clinical model of patients who received high-dose cyclophosphamide (HDCY 45 g/m2) for the treatment of an underlying malignancy in order to investigate the optimal time (preemptive vs. supportive) of G-CSF initiation upon the(More)
Infections associated with double-lumen central venous catheters (CVCs) in patients undergoing BMT are presented. We prospectively studied infections occurring with 46 CVCs in 40 patients with malignancies during and up to 30 days after BMT. We randomised patients with insertions of CVCs to receive either a short course of vancomycin 500 mg x 3(More)
UNLABELLED The 1997 International staging system (ISS) classification separated stage III non-small cell lung cancer (NSCLC) into stages IIIA and IIIB. In a previous study including unresectable NSCLC initially treated with chemotherapy, we analysed survival according to tumour (T) and node (N) stages and derived a classification into stages IIIbeta(More)
The basement membrane, immune cells, capillaries, fibroblasts and extracellular matrix (ECM) constitute the tumour stroma, commonly referred to as the 'reactive stroma'. The fibroblasts from the initial stages of a tumour, as the main constituents of the reactive stroma, present a different phenotype from the normal fibroblasts and play a crucial role in(More)
Among the most distressing symptoms experienced by patients who have undergone high-dose chemotherapy and stem cell transplantation are nausea and vomiting. The chemotherapy regimens used in high-dose conditioning protocols are highly emetogenic. The 5HT3 receptor antagonists are very effective in the prevention and abolition of nausea and vomiting(More)
The present study describes a rare case of a mesen-teric liposarcoma that resulted in a complete remission (CR) following treatment with trabectedin (Yondelis ®). The patient presented with abdominal pain and fever. An abdominal mass was identified that corresponded to a mixed‑type high‑grade mesenteric liposarcoma with wide areas of necrosis, areas of(More)
The purpose of this study was to evaluate the efficacy and tolerance of combined treatment with docetaxel-cisplatin as first-line chemotherapy in patients with metastatic breast cancer (MBC). Consecutive eligible chemonaive patients received docetaxel 75 mg/m(2) on day 1 and cisplatin 75 mg/m(2) on day 2 every 3 weeks for 6 cycles, with prophylactic(More)
PURPOSE To assess the antitumor efficacy and safety of a vinorelbine and cisplatin combination in patients with metastatic breast cancer previously treated with anthracyclines. PATIENTS AND METHODS Fifty-three patients with assessable metastatic breast cancer with previous exposure to anthracyclines (adjuvant n = 6, palliative n = 47) were studied.(More)
