  • Independent risk factors for anemia in cancer patients receiving chemotherapy : results from the European Cancer Anaemia Survey
  • 2006

    • 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 : pathogenesis, prevalence and treatment
  • 2005
  • Ingår i: Oncology. - : S. Karger AG. - 0030-2414 .- 1423-0232. ; 68:Suppl 1, s. 3-11

    • 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.

  • New guidelines on anaemia management in patients with cancer : How do these affect clinical practice?
  • 2005
  • Ingår i: Oncology. - : S. Karger AG. - 0030-2414 .- 1423-0232. ; 69:Suppl 2, s. 17-21

    • 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.

  • Addition of aprepitant (EMEND®) to standard antiemetic care during seven days post chemotherapy before stem cell transplantation provides significant reduction of vomiting
  • 2015

    • Chemotherapy-induced nausea/vomiting (CINV) is a major problem for patients treated with high-dose chemotherapy (HDCT) conditioning before stem cell transplantation (SCT), both during chemotherapy and afterwards (delayed nausea/vomiting). The standard of care (5-HT3 antagonist and dexamethasone) appears to be ineffective against delayed nausea and vomiting. The objective of this study was to compare standard antiemetic treatment with standard treatment plus prolonged treatment with aprepitant (Emend®) until 7 days after the end of chemotherapy in patients treated with HDCT before autologous SCT. Ninety-six patients were randomized to the experiment (EXP) group receiving Emend in addition to standard antiemetics or to the control (CTR) group receiving placebo. Emend or placebo treatment started 1 h before the first HDCT dose for SCT and ended 7 days after HDCT. Thirty-eight patients in the EXP group experienced complete response (no vomiting) compared to 16 patients in the CTR group. There was a significant difference between the EXP (0.63 ± 2.71) and the CTR (3.72 ± 4.91) group during 10 days after the end of HDCT (p = 0.001) with regard to the number of vomiting episodes. No difference with regard to days of nausea or in the use of antiemetic rescue was noted between the groups. We conclude that standard antiemetic treatment can be improved by addition of aprepitant continued for 7 days after the end of chemotherapy.
