- BACKGROUND: To decrease recurrences in non-muscle-invasive bladder cancer (NMIBC), the European Association of Urology (EAU) guidelines recommend immediate, intravesical chemotherapy after transurethral resection (TUR) for all patients with Ta/T1 tumours. OBJECTIVE: To study the benefits of a single, early, intravesical instillation of epirubicin after TUR in patients with low- to intermediate-risk NMIBC. DESIGN, SETTING, AND PARTICIPANTS: In this prospective randomised multicentre trial, 305 patients with primary as well as recurrent low- to intermediate-risk (Ta/T1, G1/G2) tumours were enrolled between 1997 and 2004. Patients were randomly allocated to receive 80mg of epirubicin in 50ml of saline intravesically within 24h of TUR or no further treatment after TUR. MEASUREMENTS: The primary end point was time to first recurrence. RESULTS AND LIMITATIONS: A total of 219 patients remained for analysis after exclusions. The median follow-up time was 3.9 yr. During the study period, 62% (63 of 102) of the patients in the epirubicin group and 77% (90 of 117) in the control group experienced recurrence (p=0.016). In a multivariate model, the hazard ratio (HR) for recurrence was 0.56 (p=0.002) for early instillation of epirubicin versus no treatment. In a subgroup analysis, the treatment had a profound recurrence-reducing effect on patients with primary, solitary tumours, whereas it provided no benefits in patients with recurrent or multiple tumours. Furthermore, patients with a modified European Organisation for Research and Treatment of Cancer (EORTC) risk score of 0-2 with and without single instillation had recurrence rates of 41% and 69%, respectively (p=0.003), whereas the corresponding rates for those with a risk score of >/=3 were 81% and 85%, respectively (p=0.35). CONCLUSIONS: A single, early instillation of epirubicin after TUR for NMIBC reduces the likelihood of tumour recurrence; however, the benefit seems to be minimal in patients at intermediate or high risk of recurrence. Future trials will determine the value of early instillation in addition to serial instillations in NMIBC.

- INTRODUCTION: Rituximab has significantly improved the prognosis for patients with both indolent and aggressive non-Hodgkin's lymphoma. An economic evaluation was carried out to assess the cost-effectiveness in Sweden of rituximab as maintenance therapy for patients with follicular lymphoma in remission after second line therapy. MATERIALS AND METHODS: The incremental cost and effectiveness of rituximab maintenance therapy versus observation were evaluated in a health-state transition model. Primary effect measures were quality-adjusted life-years (QALY) and life-years gained (LYG). Model state transitions were calculated based on progression-free and overall survival data from the EORTC20981 trial. The analysis was made from the perspective of the healthcare provider, including direct medical costs presented in euro, 2007 value. Effects and costs were discounted at a 3% annual rate. The stability of the base case results were tested in one-way and probabilistic sensitivity analyses. RESULTS: The evaluation assessed rituximab maintenance therapy to be associated with an incremental cost per QALY gained of euro 12,600 and an incremental cost per LYG of euro 11,200. The average discounted life expectancy for patients on rituximab maintenance was 1.0 year longer than for patients on observation (5.96 vs. 4.94 years). Rituximab maintenance was associated with an additional 0.9 QALY, and total costs per patient were euro 11,500 higher in the treatment arm, compared to observation. DISCUSSION: The results indicate that rituximab maintenance treatment after successful induction therapy for patients with relapsed/refractory follicular lymphoma in Sweden is cost-effective compared to observation.

- This study is a consequence of a distinct fish decline in the Danube river since the beginning of the 1990s. In contrast to the decline of fish population, former studies have repeatedly documented that the water quality along the Danube river is improving. However, the conclusion of a pilot study in 2002 was that a high hazard potential is associated with local sediments. The present study documents that sediment samples from the Danube river showed comparatively high aryl hydrocarbon receptor mediated activity in biotests, using the cell lines GPC.2D.Luc, H4IIE (DR-CALUX®) and RTL-W1. The combination of chemical analysis, fractionation techniques and different in vitro tests revealed that priority pollutants could not explain the main induction, even though the concentrations of priority polycyclic aromatic hydrocarbons (PAHs) were very high (maximum in the tributary Schwarzach, sum of 16 EPA PAHs 26 μg/g). In conclusion, this investigation shows that nonpriority pollutants mainly mediate the high induction rates. Nevertheless, owing to the effects of PAHs towards fish and the connection between dioxin-like activity and carcinogenicity, the link between contamination and the fish population decline cannot be ruled out.

- We demonstrate that X chromosome-linked inhibitor of apoptosis protein (XIAP) counteracts oxidative stress in two essentially different disease-related models of brain injury, hypoxia-ischemia and irradiation, as judged by lower expression of nitrotyrosine (5-fold) and 4-hydroxy-2-nonenal (10-fold) in XIAP-overexpressing compared with wild-type mice. XIAP overexpression induced up-regulation of at least three antioxidants residing in mitochondria, superoxide dismutase 2, thioredoxin 2 and lysine oxoglutarate reductase. Cytochrome c release from mitochondria was reduced in XIAP-overexpressing mice. Hence, in addition to blocking caspases, XIAP can regulate reactive oxygen species in the brain, at least partly through up-regulation of mitochondrial antioxidants. XIAP-induced prevention of oxidative stress was not secondary to tissue protection because although XIAP overexpression provides tissue protection after hypoxia-ischemia, it does not prevent tissue loss after irradiation. This is a previously unknown role of XIAP and may provide the basis for development of novel protective strategies for both acute and chronic neurodegenerative diseases, where oxidative stress is an integral component of the injury mechanisms involved.
