PURPOSE To compare standard therapy with bleomycin, etoposide, and cisplatin (BEP) to experimental therapy with etoposide, ifosfamide, and cisplatin (VIP) as primary treatment of men with advanced, disseminated germ cell tumors. PATIENTS AND METHODS A total of 304 men with advanced disseminated germ cell tumors were randomly allocated to receive four courses of BEP or VIP. Two hundred ninety-...

BACKGROUND SWENOTECA has since 1998 offered patients with clinical stage I (CS I) nonseminoma, adjuvant chemotherapy with one course of bleomycin, etoposide and cisplatin (BEP). The aim has been to reduce the risk of relapse, sparing patients the need of toxic salvage treatment. Initial results on 312 patients treated with one course of adjuvant BEP, with a median follow-up of 4.5 years, have b...

we determined the knowledge of parents of 200 pediatric patients for bacterial endocarditis prophylaxis (bep ), using an eight question survey pertaining to their knowledge of their child's cardiac disease, medications, and bep. the patient's cardiac lesion and current medications were verified at the time of admission for diagnostic or interventional cardiac catheterization. each pat...

Correspondence to A Addeo; alfredo.addeo@ uhbristol.nhs.uk The management of metastatic germ cell tumours (GCTs) with platinum-based chemotherapy represents a major success story. However, patients with poor-prognosis nonseminomatous GCTs (NSGCTs) with high tumour markers, non-pulmonary visceral metastases, or a mediastinal primary site at presentation have a less certain outcome. This group ac...

Benzo(e)pyrene (BeP) is a cocarcinogen with benzo(a)pyrene (BaP) and an anticarcinogen with 7,12-dimethylbenz(a)anthracene (DMBA) in mouse skin initiation-promotion assays (Slaga, T.J., Jecker, L., Bracken, W.M. and Weeks C.E. Cancer Lett. 7: 51-59, 1979). We have investigated the effects of BeP on the metabolic activation of BaP and DMBA in early-passage cultures of Syrian hamster embryo cells...

In recent years, experimental studies demonstrated negative impacts of impaired body stress response on colonic pathologies. In this study, we tested if reducing body stress response by the use of β-endorphin (BEP) neuronal transplants in the hypothalamus suppresses pre-neoplastic and neoplastic lesions. Colon cancer was induced by injecting 1,2-dimethylhydrazine (DMH) for sixteen weeks in Spra...

BACKGROUND To report the long-term results of adjuvant treatment with one cycle of modified bleomycin, etoposide, and cisplatin (BEP) in patients with clinical stage I (CS I) nonseminomatous germ-cell tumors (NSGCT) at high risk of relapse. PATIENTS AND METHODS In a single-arm, phase II clinical trial, 40 patients with CS I NSGCT with vascular invasion and/or >50% embryonal cell carcinoma in ...
