“…In a non-randomised study of 191 patients undergoing neoadjuvant chemoradiotherapy and resection for squamous cell carcinoma of the oral cavity or oropharynx, treatment with epoetin was associated with significantly better local control and survival compared with an untreated historical control group (Glaser et al, 2001). Similarly, in a preliminary report, treatment with epoetin improved tumour control and survival in a randomised controlled trial of 385 patients with various pelvic malignancies receiving radiotherapy (Antonadou et al, 2001). A nonsignificant trend towards a survival benefit with epoetin has also been suggested by the results of a randomised, double-blind, placebo-controlled trial of 375 patients with solid or non-myeloid haematological malignancies receiving non-platinum-based chemotherapy (Littlewood et al, 2001).…”

“…Preclinical data have indicated that administration of epoetin can enhance response to therapy and delay tumour progression (Mittelman et al, 2001;Thews et al, 2001;Stuben et al, 2003), whereas early clinical studies have suggested a potential survival benefit associated with epoetin in patients receiving radiotherapy and/or chemotherapy (Antonadou et al, 2001;Glaser et al, 2001;Littlewood et al, 2001). This hypothesis is supported by results of a meta-analysis of randomised controlled trials that reported a trend towards increased survival in patients treated with erythropoietic agents (Bohlius et al, 2005).…”

Effect of treatment with epoetin beta on short-term tumour progression and survival in anaemic patients with cancer: a meta-analysis

To assess the early effect of epoetin beta on survival and tumour progression in anaemic patients with cancer, data were pooled from nine randomised clinical trials comparing epoetin beta with placebo or standard care. Studies were not primarily designed to assess these end points. Follow-up was for treatment duration plus 4 weeks following therapy completion. All adverse events (AEs) were retrospectively reviewed blinded, for progression. Thromboembolic events were also assessed. Data analysis involved standard statistical tests. Overall, 1413 patients were included (epoetin beta, n ¼ 800; control, n ¼ 613; 56% haematological, and 44% solid). Median initial epoetin beta dose was 30 000 IU/week. Overall survival during months 0 -6 was similar with epoetin beta and control (0.31 vs 0.32 deaths/patient-year). No increased mortality risk was seen with epoetin beta (relative risk (RR) 0.97, 95% CI: 0.69, 1.36; P ¼ 0.87). There was a significantly reduced risk of rapidly progressive disease for epoetin beta (RR 0.78, 95% CI: 0.62, 0.99; P ¼ 0.042). Epoetin beta was associated with a slightly higher frequency of thromboembolic events vs control (5.9% vs 4.2% of patients) but thromboembolic-related mortality was identical in both groups (1.1%). Epoetin beta provided a slight beneficial effect on tumour progression and did not impact on early survival or thromboembolic-related mortality.

“…Moreover, in clinical studies, a potential survival benefit has been shown in patients undergoing cancer therapy who received treatment with ESAs (Antonadou et al, 2001;Glaser et al, 2001;Littlewood et al, 2001). The results of the first meta-analysis of 19 randomised, controlled trials in 2865 cancer patients receiving ESAs, reported by the Cochrane Group, showed a trend towards increased survival in patients treated with ESAs (hazard ratio (HR) ¼ 0.81; 95% CI: 0.67, 0.99; P ¼ 0.04) and lent support to these findings (Bohlius et al, 2005).…”

Effect of treatment with epoetin-β on survival, tumour progression and thromboembolic events in patients with cancer: an updated meta-analysis of 12 randomised controlled studies including 2301 patients

Epoetin-b is used to treat patients with metastatic cancer undergoing chemotherapy to alleviate the symptoms of anaemia, reduce the risk of blood transfusions and improve quality of life. This meta-analysis of 12 randomised, controlled studies evaluated the impact of epoetin-b on overall survival, tumour progression and thromboembolic events (TEEs). A total of 2297 patients were included in the analysis (epoetin-b, n ¼ 1244; control, n ¼ 1053; 65% solid and 35% nonmyeloid haematological malignancies). A prespecified subgroup analysis assessed the effects in patients with a baseline Hbp11 g dl À1 , corresponding to current European Organisation for Research and Treatment of Cancer (EORTC) guidelines. No statistically significant effect on mortality was observed with epoetin-b vs control, both overall (hazard ratio (HR) ¼ 1.13; 95% CI: 0.87, 1.46; P ¼ 0.355) and in patients with baseline Hbp11 g dl À1 (HR ¼ 1.09; 95% CI: 0.80, 1.47; P ¼ 0.579). A trend for a beneficial effect on tumour progression was seen overall (HR ¼ 0.85; 95% CI: 0.72, 1.01; P ¼ 0.072) and in patients with an Hbp11 g dl À1 (HR ¼ 0.80; 95% CI: 0.65, 0.99; P ¼ 0.041). An increased frequency of TEEs was seen with epoetin-b vs control (7 vs 4% of patients); however, TEEs-related mortality was similar in both groups (1% each). The results of this meta-analysis indicate that when used within current EORTC treatment guidelines, epoetin-b has no negative impact on survival, tumour progression or TEEs-related mortality.
