Synergistic effect of peplomycin in combination with bleomycin on L5178y mouse lymphoma cells in vivo.
1984
Studying the treatment of NMRI mice with ip injections of bleomycin (BLM) for 5 days we found an approximate LD50 of 35 mg/kg; the toxicity of peplomycin (PEP) was slightly higher (LD50: approximately 25 mg/kg). The effect of the two drugs on growth of L5178y mouse lymphoma cells in NMRI mice was examined. BLM alone caused at a concentration of 2.5 mg/kg an almost complete inhibition of tumor cell growth; the same effect was determined with 1 mg PEP/kg. At these concentrations the drugs caused an increase of the survival time of 110% (BLM) or 104% (PEP). Given in combination, one-sixth of the optimal doses yielded an 100% increase of the median survival time. These results indicate a signif…
Coagulation factors and proteinase inhibitors in the plasma of children with acute lymphoblastic leukoses. Behaviour before and during treatment acco…
1984
The thrombocyte count, the factor XIII (F XIII) activity, the concentration of fibrinogen (F I), prothrombin (F II), fibronectin (CIG), albumin and the proteinase inhibitors antithrombin III (AT III), alpha 2-macroglobulin (A2M), alpha 1-antitrypsin (A1A) and Cl-esterase inactivator (Cl-INA) were determined in ten children with acute lymphoblastic leukaemia (ALL). Changes due to the disease and to therapy were observed. Before the start of treatment the patients had thrombocytopenia secondary to the disease, and the proteinase inhibitors--especially Cl-INA and A1A--were raised. During the induction phase the thrombocyte count rose but there was also a marked increase in the concentration of…
Nephroblastoma: does the decrease in tumor volume under preoperative chemotherapy predict the lymph nodes status at surgery?
2011
Background Partial nephrectomy (NSS) for unilateral nephroblastoma may be beneficial, although in case of regional lymph node (LN) involvement, radiotherapy counteracts the functional benefit of NSS. The aim is to verify whether decrease of tumor volume under preoperative chemotherapy implies clearance of regional LN. Procedure SIOP 9301 (1993–2001) collected 1,450 localized nephroblastoma patients of whom 1,360 (93%) had sufficiently available data and were retrospectively reviewed. Results Histologic subtypes were classically distributed. Patients were divided in those with tumor positive LN (76, 5.5%) and those with tumor negative LN (1,284, 94.5%) at surgery. In the LN(+) group, the tum…
A prospective, randomized study of empirical antifungal therapy for the treatment of chemotherapy-induced febrile neutropenia in children
2012
Given that the rationale for empirical antifungal therapy in neutropenic children is limited and based on adult patient data, we performed a prospective, randomized, controlled trial that evaluated 110 neutropenic children with persistent fever. Those at high risk for invasive fungal infections (IFI) received caspofungin (Arm C) or liposomal amphotericinB (Arm B); those with a lower risk were randomized to receive Arm B, C, or no antifungal treatment (Arm A). Complete response to empirical antifungal therapy was achieved in 90/104 patients (86·5%): 48/56 at high risk (85·7%) [88·0% in Arm B; 83·9% in Arm C (P = 0·72)], and 42/48 at low risk (87·5%) [87·5% in control Arm A, 80·0% Arm B, 94·1…
Weekly oxaliplatin, high-dose folinic acid and 24h-5-fluorouracil (FUFOX) as salvage therapy in metastatic colorectal cancer patients pretreated with…
2002
Irinotecan (CPT-11), oxaliplatin (OXA) and different folinic acid (FA) modulated 5-fluorouracil (5-FU) regimens are active as first-and second-line chemotherapy of metastatic colorectal cancer. However, the best palliative sequence of these substances is still unclear. After CPT-11 containing regimens the optimal salvage protocol has not yet been defined. Here, we retrospectively analysed the weekly ambulant combination of OXA with continuous FA/5-FU (FUFOX) after two different CPT-11 containing chemotherapeutic regimens. Patients: During October 1999 and May 2001, 20 patients (median 62; 48-74 years) were included who had disease progression after CPT-11/bolus FA/5-FU (Saltz; 7 patients, g…
Chemoembolization for primary liver cancer
2002
Abstract Aims: For most patients with primary liver cancer surgical treatment is not feasible and prognosis without treatment is poor. We aimed to assess the morbidity and efficacy of transarterial chemoembolization (TACE) with lipiodol and mitomycin C in these patients in a prospective case-control study. Methods: From August 1996 to May 2000 22 patients with non-resectable hepatocellular carcinoma were treated with TACE. In case of radiological or tumour-marker response, treatment was repeated after 4–6 weeks, up to seven times per patient. Results: Morbidity was 23% and usually minor, no patient died within 30 days of treatment. A decrease in size of the reference tumour or constant tumo…
Midterm follow-up after DC-BEAD™-TACE of Hepatocellular Carcinoma (HCC)
2012
Abstract Aim To determine local response, its predictors and survival and complication rates after DC-Bead™-TACE in patients with hepatocellular carcinoma (HCC). Materials and methods DC-Beads™ are non-resorbable, polyvinyl-alcoholic hydrophilic microspheres. They release high amounts of chemotherapeutics directly into the tumour. Delivery is sustained over time, tumour feeders are embolised. We used beads from 100–300 to 500–700 μm loaded with Doxorubicin (max. 150 mg/4 ml). Fifty patients (mean age: 68.5 ± 8.8 years) with HCC were analysed. DC-Bead™-TACE was performed once or repeated in two-month intervals. Imaging scans (CT or MRI) were done one-month following each procedure. To evalua…
Organ recipients suffering from undifferentiated neuroendocrine small-cell carcinoma of donor origin: a case report.
2009
Abstract Background Transmission of donor-derived cancer by organ transplantation is rare, but the risk has been increasing due to the aging donor pool. Undifferentiated neuroendocrine small-cell carcinoma is an agressive tumor with the tendency to spread. Herein we have demonstrated different approaches to treat organ recipients with transmitted tumors. Methods and Results Grafts were retrieved from a decreased donor without any history of previous diseases. Autopsy was not performed after donation. The recipient of the liver graft presented with suspected nodules on routine abdominal ultrasound. After computed tomography (CT) scan, biopsy confirmed the diagnosis of a small-cell carcinoma.…
Treatment of hepatocellular carcinoma: A systematic review of randomized controlled trials
1997
Summary Background Hepatocellular carcinoma (HCC) is a leading cause of cancer-related death. Many treatments have been proposed but considerable uncertainty still remains about their effectiveness. In this review we evaluated the quality, clinical coherence, consistency and results of Randomized Controlled Trials (RCT) of non-surgical treatments for HCC. Methods Thirty-seven RCTs examining the effect of different treatments were retrieved using MEDLINE (November 1978 to December 1995) and a review of reference lists. Selected aspects of the quality of design, conduct and reporting were examined. The odds ratio for the probability of surviving up to one year was calculated according to the …
Chemo-radiotherapy induced oral mucositis during IMRT for head and neck cancer: an assessment
2014
Background This study is conducted mainly to evaluate the changes in quality and quantity of oral epithelial cells during the course of IMRT. Material and Methods 30 Patients undergoing chemo-radiotherapy were followed through course of treatment. They were compared with a group of age- and sex-matched healthy individuals. The procedure involved WHO clinical scoring, collection of oral washings and preparation of buccal smears from both study group and control group. The changes occurred were recorded as a way of assessing the severity of oral mucositis. Results Revealed a significant occurrence of oral mucositis in almost all patients during weekly follow up. There was a significant increa…
