- OBJECTIVES: To develop a hitherto unavailable risk factor model for accurately predicting anemia development in cancer patients before chemotherapy (CT) administration. METHODS: 2,070 nonanemic patients from the European Cancer Anaemia Survey (ECAS) with hemoglobin (Hb) > or =12 g/dl at enrollment who received their first CT during ECAS and underwent at least two CT cycles were divided randomly into split half (SH) 1 and SH2 (n = 1,035 each). The model was developed on SH1 using logistic regression to simultaneously evaluate predictive factors, and was validated using SH2 and an additional similar subpopulation of 5,901 ECAS patients. Anemia risk values were assigned to the predictive factors and the sum of the predictive factors gave the total anemia risk score; lower-, higher-, and highest-risk cutoff points of the total anemia risk score were determined. RESULTS: Variables ultimately identified as significant predictive factors for anemia were: lower initial Hb (< or =12.9 g/dl in females, and < or =13.4 g/dl in males); having lung or gynecologic cancer versus gastrointestinal (GI)/colorectal cancer; cancer at any other site versus GI/colorectal cancer; treatment with platinum CT, and female gender. CONCLUSION: Using this evidence-based risk model, nonanemic patients who are at the highest risk of developing anemia prior to receiving CT can be identified clinically, allowing appropriate anemia management to be planned.

- Cancer-related anemia is a cytokine-mediated disorder resulting from complex interactions between tumor cells and the immune system. Overexpression of certain inflammatory cytokines results in shortened survival of red blood cells, suppression of erythroid progenitor cells, impaired iron utilization, and inadequate erythropoietin production. Numerous other factors may also contribute to the development of anemia in cancer patients. The European Cancer Anaemia Survey (ECAS) has provided the most current, comprehensive, prospectively collected data on the incidence and prevalence of anemia among cancer patients, as well as important perspectives on anemia treatment and relationship of hemoglobin and performance status. ECAS enrolled over 15,000 treated and untreated patients with various malignancies from cancer centers in 24 European countries and followed them for up to 6 months. The initial analysis of the ECAS data revealed that 39% of the total cancer patient population was anemic (hemoglobin <12.0 g/dl) at enrollment, although the rate varied according to tumor type, disease status, and cancer treatment status. Of the patients who were not anemic at enrollment and started cancer treatment during the survey, those undergoing chemotherapy--either alone or in combination with radiotherapy--had the highest incidence of anemia (63 and 42%, respectively). Low hemoglobin levels correlated with poor performance status and only 40% of patients who were anemic at some time during the survey received treatment for their anemia. These findings are noteworthy, since a growing body of clinical evidence indicates that the treatment of anemia can significantly improve patients' quality of life and may also improve the clinical outcome.

- Anaemia is a condition that frequently occurs in patients with cancer, but a recent survey has cast doubt over whether it is being appropriately treated. These findings are disappointing considering the wealth of data showing the effectiveness of epoetin therapy in patients with cancer. Recently, evidence-based guidelines have been published that aim to provide physicians with the latest information required for optimal management of anaemia in patients with cancer. By increasing physician awareness of the appropriate therapy for anaemia management, more patients may receive the benefits of epoetin therapy.

- Objectives: The first consensus report presented by the European Germ Cell Cancer Consensus Group (EGCCCG) in the year 2004 has found widespread approval by many colleagues throughout the world. In November 2006, the group met a second time under the auspices of the Department of Urology of the Amsterdam Medical Center, Amsterdam, The Netherlands. Methods: Medical oncologists, urological surgeons, radiation oncologists as well as pathologists from several European countries reviewed and discussed the data that had emerged since the 2002 conference, and incorporated the new data into updated and revised guidelines. As for the first meeting, the methodology of evidence-based medicine (EBM) was applied. The results of the discussion were compiled by the writing committee. All participants have agreed to this final update. Results: The first part of the consensus paper describes the clinical presentation of the primary tumor, its treatment, the importance and treatment of testicular intraepithelial neoplasia (TIN), histological classification, staging and prognostic factors, and treatment of stage I seminoma and non-seminoma. Conclusions: Whereas the vast majority of the recommendations made in 2004 remain valid 3 yr later, refinements in the treatment of early- and advanced-stage testicular cancer have emerged from clinical trials. Despite technical improvements, expert clinical skills will continue to be one of the major determinants for the prognosis of patients with germ cell cancer. In addition, the particular needs of testicular cancer survivors have been acknowledged. (C) 2007 European Association of Urology. Published by Elsevier B.V. All rights reserved.

- The European Cancer Anaemia Survey (ECAS) was conducted to prospectively evaluate the prevalence, incidence and treatment of anaemia (haemoglobin <12.0 g/dL) in European cancer patients, including the relationship of mild, moderate and severe anaemia to performance status. Patients were evaluated for up to 6 months. Data (N=15367) included demographics, tumour type, performance status, haemoglobin levels, cancer treatments and anaemia treatments. Prevalence of anaemia at enrollment was 39.3% (haemoglobin <10.0 g/dL, 10%), and 67.0% during the survey (haemoglobin <10.0 g/dL, 39.3%). Low haemoglobin levels correlated significantly with poor performance status. Incidence of anaemia was 53.7% (haemoglobin <10.0 g/dL, 15.2%). Anaemia was treated in 38.9% of patients (epoetin, 17.4%; transfusion, 14.9%; and iron, 6.5%). Mean haemoglobin to initiate anaemia treatment was 9.7 g/dL. Anaemia prevalence and incidence in cancer patients are high. Anaemia significantly correlates with poor performance status and many anaemic patients are not treated.

- Cancer is a leading cause of thrombosis. We identify a new procoagulant mechanism that contributes to thromboembolism in prostate cancer and allows for safe anticoagulation therapy development. Prostate cancer-mediated procoagulant activity was reduced in plasma in the absence of factor XII or its substrate of the intrinsic coagulation pathway factor XI. Prostate cancer cells and secreted prostasomes expose long chain polyphosphate on their surface that colocalized with active factor XII and initiated coagulation in a factor XII-dependent manner. Polyphosphate content correlated with the procoagulant activity of prostasomes. Inherited deficiency in factor XI or XII or high-molecular-weight kininogen, but not plasma kallikrein, protected mice from prostasome-induced lethal pulmonary embolism. Targeting polyphosphate or factor XII conferred resistance to prostate cancer-driven thrombosis in mice, without increasing bleeding. Inhibition of factor XII with recombinant 3F7 antibody reduced the increased prostasome-mediated procoagulant activity in patient plasma. The data illustrate a critical role for polyphosphate/factor XII-triggered coagulation in prostate cancer-associated thrombosis with implications for anticoagulation without therapy-associated bleeding in malignancies.

- This two-arm, randomised, multicentre, open-label, phase IIIb study investigated the safety and efficacy of a 3-h catumaxomab infusion with/without prednisolone premedication to reduce catumaxomab-related adverse events. Patients with malignant ascites due to epithelial cancer received four 3-h intraperitoneal catumaxomab infusions with/without intravenous prednisolone (25 mg) premedication before each infusion. The primary safety endpoint was a composite safety score calculated from the incidence and intensity of the most frequent catumaxomab-related adverse events (pyrexia, nausea, vomiting and abdominal pain). Puncture-free survival (PuFS) was a co-primary endpoint. Time to next puncture (TTPu) and overall survival (OS) were secondary endpoints. Prednisolone premedication did not result in a significant reduction in the main catumaxomab-related adverse events. The mean composite safety score was comparable in both arms (catumaxomab plus prednisolone, 4.1; catumaxomab, 3.8; p = 0.383). Median PuFS (30 vs. 37 days) and TTPu (78 vs. 102 days) were shorter in the catumaxomab plus prednisolone arm than in the catumaxomab arm, but the differences were not statistically significant (p = 0.402 and 0.599, respectively). Median OS was longer in the catumaxomab plus prednisolone arm than in the catumaxomab arm (124 vs. 86 days), but the difference was not statistically significant (p = 0.186). The superiority of catumaxomab plus prednisolone versus catumaxomab alone could not be proven for the primary endpoint. Prednisolone did not result in a significant reduction in the main catumaxomab-related adverse events. The study confirms the safety and efficacy of catumaxomab administered as four 3-h intraperitoneal infusions for the treatment of malignant ascites.
