Relative survival of patients with non-malignant central nervous system tumours: a descriptive study by the Austrian Brain Tumour Registry.

BACKGROUND: Unlike malignant primary central nervous system (CNS) tumours outcome data on non-malignant CNS tumours are scarce. For patients diagnosed from 1996 to 2002 5-year relative survival of only 85.0% has been reported. We investigated this rate in a contemporary patient cohort to update information on survival. METHODS: We followed a cohort of 3983 cases within the Austrian Brain Tumour Registry. All patients were newly diagnosed from 2005 to 2010 with a histologically confirmed non-malignant CNS tumour. Vital status, cause of death, and population life tables were obtained by 31 December 2011 to calculate relative survival. RESULTS: Overall 5-year relative survival was 96.1% (95% CI 95.1-97.1%), being significantly lower in tumours of borderline (90.2%, 87.2-92.7%) than benign behaviour (97.4%, 96.3-98.3%). Benign tumour survival ranged from 86.8 for neurofibroma to 99.7% for Schwannoma; for borderline tumours survival rates varied from 83.2 for haemangiopericytoma to 98.4% for myxopapillary ependymoma. Cause of death was directly attributed to the CNS tumour in 39.6%, followed by other cancer (20.4%) and cardiovascular disease (15.8%). CONCLUSION: The overall excess mortality in patients with non-malignant CNS tumours is 5.5%, indicating a significant improvement in survival over the last decade. Still, the remaining adverse impact on survival underpins the importance of systematic registration of these tumours.

Vinorelbine-gemcitabine in advanced non-small-cell lung cancer (NSCLC): an AASLC phase II trial. Austrian Association for the Study of Lung Cancer.

PURPOSE: The purpose of the present phase 11 trial was to determine the efficacy and toxicity of vinorelbine-gemcitabine in patients with advanced non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: From December 1997 to February 1999, 78 chemotherapy-naive patients (median age 60 years, Karnofsky performance status of 100, 90, 80 and 70 present in 5%, 41%, 36% and 18% of the patients, respectively) with stage IIIB (17%) or IV (83%) NSCLC (65% adenocarcinomas, 22% squamous-cell carcinomas, 10% large-cell carcinomas, 3% mixed-cell carcinomas) received 25 mg/m2 vinorelbine and 1200 mg/m2 gemcitabine on days 1, 8 and 15 of a four-week cycle. RESULTS: In an intent-to-treat analysis, partial responses were seen in 19% of the patients. The median duration of response was 4.4 months. The median survival time was seven months and the one-year survival rate was 32%. Myelosuppression was the main side effect with WHO grade 3/4 neutropenia and thrombocytopenia in 35% and 11% of the patients, respectively. Other side effects were usually mild to moderate. CONCLUSIONS: Vinorelbine-gemcitabine is active, well tolerated and easy to administer on an outpatient basis in advanced NSCLC. Thus a randomized comparison of this combination with platinum-based protocols is warranted in patients with advanced NSCLC.

Vinorelbine/gemcitabine in advanced non-small cell lung cancer (NSCLC): a phase I trial.

Vinorelbine and gemcitabine are both active as single agents in advanced non-small cell lung cancer (NSCLC). Because of their different mechanisms of action, good tolerability and possible administration on an out-patient basis, vinorelbine/gemcitabine should be an interesting combination for palliative chemotherapy. Thus, we initiated a phase I dose-escalation trial in order to determine the maximum tolerated doses of vinorelbine/gemcitabine that can be administered without haematopoietic growth factors, the dose-limiting toxicities and the most frequent side-effects of this novel combination. 40 chemotherapy-naïve patients with advanced NSCLC were treated with different doses of vinorelbine/gemcitabine on days 1, 8 and 15, and this treatment cycle was repeated on day 29. Vinorelbine and gemcitabine were escalated from 10 to 30 mg/m2 and 600 to 1200 mg/m2, respectively. A total of 63 treatment cycles were administered and 27 patients received at least two treatment cycles. Dose-limiting toxicities were leucopenia plus thrombocytopenia (2 patients) and mucositis (1 patient). The maximum tolerated dose was established at 25 mg/m2 vinorelbine combined with 1200 mg/m2 gemcitabine. Frequent side-effects were leucopenia, anaemia, nausea/vomiting, flu-like symptoms, skin rashes and elevation of liver enzymes. The recommended phase II doses are 20-25 mg/m2 vinorelbine combined with 1000-1200 mg/m2 gemcitabine on days 1, 8 and 15, but myelosuppression will have to be carefully monitored.
