model. A piecewise linear change-point Poisson regression model was used to compare mortality rates in Tyrol and the rest of Austria. Standardized mortality ratios were calculated with reference to the mortality rates in [1986][1987][1988][1989][1990]. RESULTSIn all, 86.6% of eligible men have been tested at least once since 1993. Cancer deaths in Tyrol in 2005 were 54% (95% confidence interval [CI] 34-69%) lower than expected compared with 29% (95% CI 22-

The aim of our study was to examine whether an extensive surveillance protocol will promote early diagnosis and improved survival in patients with de novo cancer following liver transplantation (LT). Of 779 consecutive LT recipients, 96 (12.3%) developed 105 malignancies. The cumulative risk for the development of de novo cancer was 10%, 24%, 32% and 42% at 5, 10, 15 and 20 years after LT, respectively. The most frequent tumor types were skin (17%), lung (16%), oropharyngeal (11%) and prostate cancer (11%). The overall standard incidence ratio as compared to that of the general population was 1.9 (95% CI: 1.5-2.3). The median survival of patients with de novo non-skin cancers was 3.1 years after diagnosis. Only patients with skin cancers and solid tumors, diagnosed at early stages, showed an excellent outcome. After introducing an intensified surveillance protocol, the detection rate of de novo cancers increased from 4.9% to 13% and more de novo malignancies were diagnosed in earlier stages. For non-skin cancers, the median tumor-related survival significantly improved from 1.2 to 3.3 years as well as the median overall survival post-LT. This study indicates that an extensive tumor surveillance program is highly recommendable in LT recipients.

We aimed to provide a rationale for optimal dosing and scheduling of this anti-CD20 antibody based on pharmacokinetics. Design and MethodsClinical efficacy of immuno-chemotherapy with rituximab, fludarabine and mitoxantrone followed by 2-monthly rituximab maintenance was evaluated in 29 patients with previously untreated follicular lymphoma in a prospective phase II trial (AGMT-NHL9). Pharmacokinetic analysis was assessed in 17 patients. ResultsInduction treatment resulted in high clinical response rates (complete remission 66%; ORR 100%). Significantly higher complete remission rates were observed in female patients (86 vs. 47%; Odds Ratio 6.8, 95% CI: 1.12; 41.82; P=0.05). Rituximab pharmacokinetic analysis showed a high variability ranging over almost 1 order of magnitude at maintenance cycle 1 (area under the curve 1,540-12,025 g/L*days). Median area under the curve was lower in men (81%) and in patients with initial bone marrow infiltration (76%). Higher rituximab serum concentrations before next therapy (Ctrough) were associated with female sex (P=0.04) as well as with absence of initial bone marrow infiltration (P=0.001). Ctrough correlated with remission quality (complete vs. partial remission; P=0.005) and progression-free survival (P=0.03). A decline in rituximab Ctrough below 25,000 ng/mL was observed 9.5 to 62 months before clinical relapse (P=0.008). ConclusionsThe results of this pilot trial suggest that more differentiated dosing schedules based on gender and bone marrow infiltration should be explored for rituximab therapy for lymphoma. This study was registered in ClinicalTrials.gov (Identifier: NCT01560117). ABSTRACT © F e r r a t a S t o r t i F o u n d a t i o n © F e r r a t a S t o r t i F o u n d a t i o n

Background: It has been hypothesized that serum uric acid (SUA), via its antioxidant properties may protect against carcinogenesis. However, few epidemiological investigations have addressed this association and previous findings are inconsistent. Patients and methods:We prospectively investigated the relation of SUA levels to subsequent cancer mortality in a large cohort of 28613 elderly Austrian women with a median follow-up of 15.2 years. Adjusted Cox proportional hazards models were calculated to evaluate SUA as an independently related factor to fatal cancer events.Results: High SUA (>5.41 mg/dL) was independently associated with increased risk of total cancer mortality (p<0.0001); the adjusted hazard ratio for the highest versus lowest quartile of SUA was 1.27 (1.08-1.48). SUA levels were further positively related to deaths from malignant neoplasms of breast and female genital organs (P = 0.02) and nervous system and unspecified sites (P = 0.02). We found no evidence for an inverse relationship between SUA levels and risk of total or site-specific cancer mortality. Conclusion:Our results are contrary to the proposed antioxidant and protective effect of SUA against cancer and rather suggest high SUA concentrations to be associated with outcome possibly reflecting more serious prognostic indication.

We determined mortality rates and predictors of survival in 238 consecutive patients with Parkinson's disease (PD) with symptom onset between 1974 and 1984. All patients were regularly followed at the Movement Disorder Clinic (Department of Neurology at the Innsbruck Medical University) until December 31, 2004, or death. As of December 31, 2004, 189 patients had died. Standardized mortality ratios (SMRs) increased over time. SMRs were 0.6 (95% CI 0.4-1.0) by 5 years, 0.9 (95% CI 0.7-1.2) by 10 years, 1.2 (95% CI 1.0-1.4) by 15 years, and 1.3 (95% CI 1.1-1.5) by 20 to 30 years. SMR for male patients was significantly increased to 1.3 (95% CI 1.1-1.6), whereas SMR increase of 1.2 (0.9-1.4) observed in female patients was not significant. Significantly increased SMRs were detected in patients with younger and older age of onset. Male gender, gait disorder, lack of tremor, and lack of asymmetry as presenting clinical features predicted poor survival in a Cox's proportional hazard analysis. This study demonstrates similar survival of patients with PD to the normal control population up to a disease duration of 10 years, followed by a modest rise of mortality with disease duration beyond 10 years compared with the general population. Under regular specialist care using all currently available therapies life expectancy in PD does not appear seriously compromised, but male gender, gait disorder, and absent rest tremor at presentation are associated with poorer long-term survival.

Iodized salt prophylaxis has been performed in Austria since 1963. Through this approach, mean urinary iodine excretion has been normalized to 144+/-23.5 microg/g creatinine per day. Thus Tyrol is no longer an endemic goiter area. We have analyzed the impact of iodized salt prophylaxis on thyroid cancer (TC) comparing data from the early 1960s with those corresponding to the period 1986 to 1995, when iodine supply was normalized. The study included 439 patients from Tyrol and Southern Tyrol. The incidence of TC in Tyrol has risen during the past decades from 3.07 between in 1957 and 1970 to 7.8 between 1990 and 1994 (CR/100000/year). We observed a rise in the percentage of differentiated adenocarcinomas (56% to 91.5%) with a predominance of papillary TC (54.4%) along with a decrease of anaplastic TC. In addition to these histological features, a shift to less advanced TNM stages, eg, T1-3, N0-1a, M0, was obvious, increasing from 29% to 72.2%, whereas advanced tumors, ie, T4 or N1b or M1, decreased from 71% to 28%. These changes have significantly improved prognosis. The current 5-year survival rate is 90.7% as compared with a rate of 73% in the 1960s; the values for 7-year survival are 89% and 48%, respectively. The marked effects of age, tumor stages, and histology on prognosis were confirmed with the Kaplan-Meier method. We conclude that together with normalization of iodine supply in an endemic goiter region the epidemiological profile of TC has changed. Even though the incidence of TC has risen, prognosis has significantly improved due to a shift towards differentiated forms of TC that are diagnosed at earlier stages.
