European guidelines for the management of chemotherapy-induced anaemia and health economic aspects of treatment

Patients with cancer receiving myelosuppressive chemotherapy frequently develop anaemia; platinum-based chemotherapy, in particular, leads to reduced production of the bone marrow-stimulating hormone erythropoietin. The European Cancer Anaemia Survey showed that many patients do not receive erythropoiesis-stimulating agent (ESA) therapy and highlighted the need for clear guidelines for the diagnosis and treatment of anaemia in cancer patients. In response to a fast-moving therapeutic environment and guidelines produced in the USA, the European Organisation for Research and Treatment of Cancer established an independent task force to develop evidence-based guidelines for the use of ESAs in European anaemic cancer patients that were first published in 2004. The guidelines recommend that, in patients receiving chemotherapy/radiotherapy, ESA therapy should be initiated at haemoglobin levels of 9-11 g/dL based on the severity of symptoms (target haemoglobin concentration: 12-13 g/dL) to improve quality of life and prevent the need for red blood cell transfusions. Treatment should be maintained as long as Hb levels remain <12-13 g/dL and patients continue to show symptomatic improvement, and should be discontinued, due to marginally elevated risks of thromboembolic events, when haemoglobin levels exceed 14 g/dL. Treatment of anaemia with ESAs is cost-effective and is associated with long-term gains in quality-adjusted life years.     

A prospective observational study of anaemia management in cancer patients - results from the German Cancer Anaemia Registry

The use of erythropoiesis-stimulating agents (ESA) in cancer patients is still under debate. However, little is known about rationales, strategies, objectives, and effectiveness of anaemia treatments in common practice. The Cancer Anaemia Registry prospectively surveyed about 2000 cancer patients with anaemia throughout Germany. The main objectives of anaemia treatment regardless of modality were to improve quality of life (QOL) and to correct haemoglobin (Hb) levels. The Hb threshold for any anaemia treatment (means ± SD: 9.4 ± 1.2 g/dL) but not for blood transfusions (8.7 ± 1.0 g/dL) depended on cancer type and treatment strategy. Physicians preferred ESA as first-line treatment to prevent transfusions in patients with solid tumours, if they thought that chemotherapy caused the anaemia. If they suspected other causes or patients had lymphoproliferative malignancies, physicians preferred transfusions or attempted to correct underlying disorders; both mainly to improve QOL or prognosis. Effectiveness of all strategies was comparable. However, ESA most effectively prevented transfusions; primary transfusions appeared less suitable for correcting Hb or improving QOL. Using supportive treatments for QOL improvement was common whereas diagnostic measures and intravenous iron therapy were underused. Prospective clinical trials using QOL as end point and evaluating diagnostics in cancer-associated anaemia are warranted.     

Management of anaemia in patient with cancer: results of the F-ACT study (French Anaemia Cancer Treatment)

Anaemia is one of the most dreaded complications among patients with malignant pathologies. Its causes can be varied and whatever its severity, the impact on the quality of life of the patient remains essential. However, the epidemiologic data concerning anaemia are very few in the literature. This is why we carried out a large national survey about the prevalence and the management of anaemia among patients with malignant diseases. The F-ACT (French Anaemia Cancer Treatment) study is a retrospective observational multicentric study conducted with 178 experts practicing in 112 centers or units treating patients with solid tumours and/or malignant haematological diseases. Control over one day standard of consultation for each questioned expert, 2 782 patients were enrolled, including 1 892 (68%) patient with solid tumour and 890 (27%) patient with malignant haematological disease. The median age was 61 years (range : 18-93 years) including 1 335 women (48%) and 1 447 men (52%). A the date of enrollment, the median level of haemoglobin (Hb) was 11,6 g/dl (range: 5,2-18,5 g/dl) and 44% of patient had a level of Hb < 11 g/dl. An anaemia was found in all the cancer localizations and whatever the stage or the therapeutic status of the disease. Approximately 2/3 of the anaemic patients received treatment by erythropoiesis stimulating agent (ESA) and approximately 17% of them did not receive any specific treatment for this anaemia. The median level of Hb at the introduction of the ESA was 10 g/dl. These results, compared with those reported in study ECAS (European Cancer Anaemia Survey) in 2001, seem to show an improvement in the management of anaemia and the use of the ESA, in particular an earlier introduction of this type of treatment since the appearance of anaemia.     

The impact and management of anaemia in haematological malignancies

Anaemia is a common disorder in patients with cancer, occurring in 10-40% of cases, depending upon the tumour type and chemotherapy used. It is present in nearly all patients with leukaemia at some time in the disease and in 50% of patients with lymphoma after chemotherapy. Cancer-related anaemia appears to result from a range of factors including chronic inflammation, blood loss, nutritional deficiencies, haemolysis, bone marrow infiltration by malignant cells, low serum erythropoietin (EPO) levels, and a decrease of bone marrow responsiveness to EPO. The consequences of anaemia, namely fatigue and cardiovascular symptoms, can adversely affect patients' quality of life and may even alter their response to cancer treatment. Moreover, anaemia is often associated with the presence of several adverse prognostic parameters and is also itself a predictor of poor prognosis. Furthermore, anaemia and its symptoms can be exacerbated by cancer treatment. Until recently, blood transfusions have been the mainstay of treatment for cancer-related anaemia, despite the associated risks of transfusion-related reactions and transmission of infection. By increasing haemoglobin levels and haematocrit, treatment with recombinant human erythropoietin (rHuEPO) has been shown to reduce the need for blood transfusion in patients with haematological malignancies. It is recommended that rHuEPO be administered when a patient's haemoglobin level is at risk of falling below 8g/dL, and that treatment is maintained until levels rise above 13g/dL. Consideration of the detrimental effects of anaemia on cancer patients' physical and emotional well-being and therapeutic outcome suggests that rHuEPO therapy has the potential to provide substantial clinical benefits.     

Prevalence and management of anaemia in patients with non-myeloid cancer undergoing systemic therapy: a Spanish survey

Background

The present study aimed to provide updated data on anaemia prevalence and management in cancer patients undergoing systemic therapy in Spain.

Methods

This was a multicenter, observational, cross-sectional study performed in 2008. Eligible patients were ≥18 years, with non-myeloid malignancies treated with systemic therapy [chemotherapy (CT), hormonal therapy or immunotherapy]. Anaemia was defined according to WHO as haemoglobin (Hb) < 12 g/dL.

Results

The study included 214 patients with a median age of 63 years (range 20–91), 58 % women, 73 % with solid tumours, and 79 % with advanced disease. CT was used in 91 % of patients (26 % with platinum compounds), hormonal therapy in 8.5 %, and immunotherapy in 8.5 %. In our study, 48.1 % of patients [95 % confidence interval (CI) 45.2–58.6] showed anaemia (31 % symptomatic): 42.0 % mild (10 ≤ Hb ≤ 11.9 g/dL), 5.6 % moderate (8 ≤ Hb ≤ 9.9 g/dL), and 0.5 % severe (Hb <  8 g/dL). A higher prevalence was observed in patients treated with CT (51 vs. 20 %, p = 0.01), platinum-based CT (70 vs. 47 %, p = 0.01) or palliative CT (61 vs. 39 %, p = 0.003). Anaemia was also more frequent in patients with more than three lines of CT (83 %) and in the fourth or subsequent CT cycle (58 %). Management in the previous 4 weeks in patients with anaemia was: 62 % did not receive treatment (92 % mild), 24 % received erythropoiesis-stimulating agents (ESAs), 14 % received iron and 8.7 % received transfusion.

Conclusions

In Spanish hospitals, about half of patients with non-myeloid malignancies undergoing systemic therapy fulfilled anaemia criteria (87 % mild). Approximately two-third of patients with anaemia do not receive specific treatment and ESA use is below current guidelines.     

Cancer-related anemia: pathogenesis, prevalence and treatment

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.     

Once-weekly epoetin beta therapy in patients with solid tumours and chemotherapy-induced anaemia: a randomized, double-blind, dose-finding study

Anaemia is common in patients receiving chemotherapy, causing symptoms that have a major impact on quality of life (QoL). Epoetin beta rapidly increases haemoglobin (Hb) levels and improves QoL in anaemic patients with a variety of tumours. This was a randomized, double-blind, parallel-group, dose-finding study assessing the efficacy and safety of once-weekly epoetin beta in patients with solid tumours receiving chemotherapy. Adult patients with anaemia (Hb < 11 g/dL) were randomized to receive epoetin beta 30,000 IU or 20,000 IU once weekly for 12 weeks. All patients received oral iron supplementation. Haemoglobin levels, transfusion need and QoL [Functional Assessment of Cancer Therapy-fatigue (FACT-F) subscale score] were assessed at regular intervals. Fifty patients were randomized; 30 patients received epoetin beta 30,000 IU once weekly and 20 received 20,000 IU once weekly. Mean (+/- SD) increase in Hb from baseline to week 12 was 1.75 +/- 2.15 g/dL in the 30,000 IU group (P = 0.008 vs. baseline) and 1.04 +/- 1.75 g/dL in the 20,000 IU group (non-significant). Haemoglobin response (increase in Hb >or=2 g/dL from baseline) was observed in 78.3% of patients receiving epoetin beta 30,000 IU and 66.7% receiving epoetin beta 20,000 IU. Improvements in FACT-F subscale score were significantly (P < 0.001) correlated with increases in Hb level. Transfusion use was low during the study in both groups. Both epoetin beta regiments were well tolerated and there were no dose-dependent adverse events. Epoetin beta 30,000 IU once weekly is an effective and well-tolerated treatment of anaemia in patients with solid tumours.     

Contraindications to cisplatin based chemoradiotherapy in the treatment of cervical cancer in Sub-Saharan Africa.

BACKGROUND AND PURPOSE: We conducted a prospective study to assess the eligibility of patients presenting with cervical cancer in the developing world for chemoradiotherapy. MATERIAL AND METHODS: Patients with biopsy proven cervical cancer were eligible. Workup included history, examination, pre-treatment Karnofsky performance score, evaluation under anaesthesia to establish FIGO stage, complete blood count, renal and liver functions tests, HIV test and ultrasound of the abdomen and pelvis. Exclusion criteria: stage IA, stage IV, HIV status positive, Karnofsky performance score <60, age >70 years, hydronephrosis, haemoglobin <8 g/dL, white cell count <2,000/microL, platelets <100,000/microL, creatinine >97 micromol/L. RESULTS: 314 patients were included. After workup, 47 patients (15.1%) were eligible for combined modality treatment and 190 (60.5%) were not eligible. Eligibility could not be established in 77 cases (24.4%). 37 (11.6%) of the group were HIV positive, HIV status was not established in 38.4% of cases. The most frequently encountered exclusion criteria were hydronephrosis and anaemia. Application of a haemoglobin cut off point of 8 g/dL for cisplatin based chemotherapy resulted in the exclusion of 55 (17.4%) patients. A limit of 10 g/dL excluded an additional 11 patients. Hydronephrosis was diagnosed on ultrasound in 99 (31.4%) patients. 56% had unilateral hydronephrosis, 44% had bilateral hydronephrosis. CONCLUSIONS: A small proportion of our patients with cervical cancer would benefit from chemoradiotherapy with concomitant cisplatin, illustrating the difficulties of applying "standard" treatment to the developing world. The introduction of national screening programmes and the provision of accessible radiotherapy facilities should be the major priorities in the developing world setting.     

Anaemia is associated with poor overall survival but not with inferior local control in patients with muscle invasive bladder carcinoma treated by radical external beam radiotherapy. A retrospective study

AimsThe treatment of muscle invasive transitional cell carcinoma of the bladder with radiotherapy allows organ preservation and is frequently used in the UK, especially in patients not medically fit for cystectomy. Anaemia is known to be an indicator of a poor response to radiotherapy in head and neck and cervical carcinomas. Here we describe the prevalence and type of anaemia in patients with transitional cell carcinoma of the bladder and determine the effect anaemia has on treatment outcome.Materials and methodsA retrospective review of notes was carried out on patients treated radically between 1992 and 1997. Potential patient, tumour and treatment prognostic indicators were reported. Patients were labelled as being anaemic if their pre-treatment haemoglobin level was below the normal range (below 13.5 g/dl for men and below 11.5 g/dl for women). The time to local failure, metastases and overall survival were recorded. Recurrence-free survival and overall survival actuarial estimations were carried out using the Kaplan–Meier method and compared by Log-rank testing. A multivariate analysis was carried out using the Cox regression method.ResultsData on 100 patients were available for analysis. Most of the patients were not adequately staged by today's standards. Fifty-two patients were anaemic, with 75% of them having a normochromic, normocytic anaemia. The univariate analysis showed no significant difference in the time to local recurrence, a trend towards a shorter time to metastases and a significant reduction in overall survival in anaemic patients (P = 0.001). Two-year survival was 43% and 22% for non-anaemic and anaemic patients, respectively. A multivariate analysis using the covariates tumour stage, grade and serum creatinine found anaemia to be a poor prognostic indicator for overall survival (P = 0.005).ConclusionAnaemia is highly prevalent in patients with bladder cancer. This retrospective study showed anaemic patients to have a worse outcome with radiotherapy treatment than patients with a normal haemoglobin level. This was not accounted for by a difference in local control, which may be expected from hypoxic radiobiological principles. Anaemia may be indicative of more aggressive malignancy or subclinical metastases.     

Impact of erythropoietin treatment on the quality of life of oncologic patients

Anaemia has a high incidence in cancer patients, especially when it is a consequence of myelosuppressive treatments. The incidence and prevalence of this condition is influenced by the type and extension of the tumour, type and intensity of the myelosuppressive treatment that patients receive, and previous surgery or intercurrent infections. Clinical manifestations of anaemia, overlapped by tumour symptomatology, depend on haemoglobin (Hb) levels; these manifestations cause impairment of the functional capacity, as well as a negative impact on the quality of life (QOL) of cancer patients as a consequence. Erythropoietin treatment for anaemia has been established as optimal for correcting Hb levels. Its impact on patients’ QOL has been evaluated in numerous randomised prospective studies by the use of diverse types of erythropoietin and administration moes. The three types of erythropoietin, alpha, beta and darbepoetin alpha, have shown a clear efficacy in all haematological parameters. This positive effect is related with significant improvements in the QOL of patients, especially those patients undergoing myelosuppressive treatments, and with regard to specific scales of fatigue and anaemia.     

The burden of anaemia in patients with cancer

Anaemia is highly prevalent in patients with cancer, and its incidence and severity depend on many factors, such as type of anti-cancer therapy. The decreased oxygen capacity of blood resulting from anaemia affects virtually every organ and tissue system in the body, manifesting in numerous signs and symptoms that include fatigue, dyspnoea, palpitations, tachycardia, asthenia, anorexia, cold hypersensitivity and general weakness. Anaemia related to cancer may also cause cognitive dysfunction, leading to decreased mental alertness, poor concentration and memory problems. There is a close association between anaemia and overall quality of life (QoL) variables, and anaemia is an adverse prognostic factor in patients with cancer. Since anaemia can seriously compromise the QoL of cancer patients and is associated with decreased overall survival time, there is a strong need for effective and well-tolerated treatment strategies. Erythropoietic agents have been proven to be safe, well-tolerated and effective in the management of anaemia in patients with cancer. Epoetin therapy reduces transfusion requirements and increases haemoglobin levels in patients with solid tumours and haematological malignancies.     

Anaemia of cancer: impact on patient fatigue and long-term outcome

Anaemia is the most common haematological abnormality encountered by cancer patients. A large European survey of cancer patients (n = 15,367) reported that 67% had anaemia at some point during the survey, and that over 60% of these patients did not receive any treatment for their anaemia. Two other surveys (the FATIGUE surveys) showed that over 75% of cancer patients experienced fatigue at least monthly, with over 30% reporting this symptom on a daily basis. Significantly, patients regarded fatigue as having a greater negative impact on their daily lives than many other cancer- or treatment-related complications, with important emotional and mental consequences including lack of self-motivation, sadness, frustration, and mental exhaustion. Indeed, fatigue was considered so debilitating, 12% of patients felt their quality of life (QoL) was so reduced that they did not wish to continue living. Anaemia is also recognised as an independent predictor of poor prognosis in cancer patients. A systematic review evaluating survival showed a 65% overall increase in the risk of mortality in cancer patients with anaemia. Increasing physicians' awareness of the importance of effectively treating anaemia in cancer patients therefore has the potential to improve prognosis as well as QoL.     

Époétine bêta dans le traitement de l'anémie liée à la chimiothérapie dans les tumeurs solides et les hémopathies malignes. Résultats d'un essai clinique,en ouvert,multicentrique

AimEvaluate efficacy and safety of epoetin beta in anaemic patients receiving chemotherapy for a non-myeloid malignancy.Patients and methodsThis open-label, multicentric, clinical trial was conducted in France among 691 anaemic patients (haemoglobin ≤ 12 g/dL) with a solid or haematological malignancy to evaluate the benefit of epoetin beta 30,000 IU/week subcutaneously for 16 weeks. The primary endpoint was the rate of therapeutic response.ResultsThe overall response rate was 60.4% (CI 95%: [56.6%-64.1]). According to initial haemoglobin level < 11 g/dL or between 11 and 12 g/dL, it was 61.2% and 57.5% respectively. Response rates by tumour type (solid and haematological) were similar. The mean haemoglobin level increases were respectively 1.1 g/dL, approximately 2 and 2.2 g/dL at 4, 9, and 12 weeks after treatment initiation. In patients with haemoglobin level < 11 g/dL at inclusion the mean increases in haemoglobin level were respectively 1.17, 2.03 and 2.45 g/dL at 4, 9 and 12 weeks. During study period, 23% of patients required red blood cell transfusion. Overall treatment with epoetin beta was well-tolerated and 7.1% of patients only experienced thromboembolic events.ConclusionFor treating chemotherapy-induced anaemia in patients with solid or haematological malignancy (especially if haemoglobin level < 11 g/dL), epoetin beta 30.000 IU subcutaneously once-weekly (450 IU/kg/week) is rapidly effective and overall well-tolerated.     

The role of haemoglobin level in predicting the response to first-line chemotherapy in advanced colorectal cancer patients

The purpose of the study was to evaluate the influence of baseline haemoglobin level in predicting response to 5-fluorouracil (5FU)-based first-line chemotherapy in advanced colorectal cancer patients. Data from 631 patients were collected from three different institutions. Globally, overall response rate was 35.8% (226 out of 631). Factors influencing response rate were 5FU dose intensity (high: 43.1%, low: 34.0%, P = 0.03); oxaliplatin (yes: 45.8%, no: 22.9%, P < 0.0001), performance status (PS 0: 46.1%, 1: 28.8%, 2: 26.7%, P < 0.0001), and haemoglobin levels (> or = 12 g dl(-1): 40.4%, < 12 g dl(-1): 29.2%, P = 0.004). In subgroup analysis significant differences in response rate between anaemic and nonanaemic patients were recorded in those patients treated with infusional chemotherapies (45.7 vs 25.5%, P < 0.0001), with high 5FU dose intensity (50.3 vs 32.7%, P = 0.005), with PS = 0 (49.8 vs 37.9%, P = 0.03), and with liver metastases (44.8 vs 33.8%, P = 0.002), whereas no difference was evident in those subjects treated with bolus schedules or according to gender. Anaemia was a strong predictor for activity of first-line 5FU-based chemotherapy especially in those groups that showed the best responses, for example high performance status, infusionally treated, higher 5FU dose and those with liver secondaries. Patients with higher haemoglobin levels recorded a greater response rate and a longer time to progression and survival than anaemic subjects. Prospective evaluation of role of correcting anaemia on response to therapy is justified by these results.     

Prevalence and Incidence of Anemia in Thai Patients with Gynecologic Cancer

This prospective, single institute, 6-month observational survey aimed to evaluate the prevalence, incidence,frequency, treatment of anemia, and trigger hemoglobin (Hb) level for initiating transfusion in patients withgynecologic malignancy. One hundred and eighty-six consecutive patients with gynecologic malignancy wereanalyzed between June and December 2009. Hb level data were collected for up to six data points or 6 months ofscheduled visits. Tumor type, disease status, cancer treatment and anemia treatment as well as trigger Hb levelfor starting treatment were evaluated. The mean age of patients was 51 years. Prevalence of anemia at enrollmentwas 66.1% (123/186), with 36 of 186 patients (19.4%) having moderate to severe anemia (Hb < 10.0 g/dl). Thehighest prevalence was found among patients with endometrial cancer (72.2%) and ovarian cancer (72%), newlydiagnosed/receiving treatment (70.9%) and those receiving radiotherapy (75%). The incidence of anemia was85.7% (54/63). Ovarian cancer had the highest association (87%). For disease status and cancer treatment, theincidence was highest in patients with persistent/recurrent disease (95.2%) and those who received radiotherapy(100%). One hundred and seventy-seven of 186 patients (95.2%) were ever anemic during the survey. Anemiawas frequently reported in patients with all tumor types (93-100%), persistent/recurrent disease (98.3%) andthose who received radiotherapy (100%) and 80.8% of patients who were ever anemic recieved treatment (oraliron, 42.9%; transfusion, 37.3%; and erythropoietic agent, 0.6%). In conclusion, the mean Hb trigger level forinitiating transfusion as treatment of anemia was 8.6g/dL. The prevalence, incidence, and frequency of anemiaare very high among patients with gynecologic malignancy; especially those with ovarian cancer, persistent/recurrent disease, and those receiving treatment.     

Iron deficiency in patients with solid tumours: prevalence and management in clinical practice

Purpose

The objective of the present study was to describe the prevalence and management of anaemia and iron deficiency (ID) in treatment-naïve patients with solid tumours in Spain and the incidence of anaemia over 4 months of cancer treatment in clinical practice.

Methods

Multicentre, prospective and observational study in newly diagnosed cancer patients. Data on anaemia and iron parameters and its management were collected prior to the initiation of chemotherapy, at each cycle of chemotherapy and after 4 months of treatment. The main outcomes of the study were the prevalence of anaemia at baseline, its incidence during cancer treatment and the prevalence of absolute ID (AID) and functional ID (FID) prior to chemotherapy initiation.

Results

A total of 295 patients were included in the study. Anaemia was present at diagnosis in 38.6 % of patients and was treated only in 32.5 % of those. A total of 106 patients (60.2 %) without anaemia at baseline developed anaemia during cancer treatment. Serum ferritin and transferrin saturation data were available for 151 of the patients (51.2 %) included in the study. The overall prevalence of ID was 59 %: 48 patients (31.8 %) presented with AID and 41 patients (27.2 %) presented with FID before starting anti-cancer therapy. Thirty-three of 44 non-anaemic iron-deficient patients did not receive any type of iron supplementation before initiating cancer therapy.

Conclusions

Iron parameters are not commonly measured in newly diagnosed cancer patients. A correct evaluation and early management of ID could reduce the incidence of treatment-related anaemia in cancer patients.     

Quantitative data on red cell measures of iron status and their relation to the magnitude of the systemic inflammatory response and survival in patients with colorectal cancer

BackgroundInflammation is recognised to be associated with perturbation of serum measures of iron status. However, the impact of colorectal cancer associated host inflammation on red cell measures of iron status has not been previously quantified.MethodsPatients undergoing elective surgery with curative intent, for colorectal cancer, at a single centre between 2008 and 2017 were included (n = 824). Blood samples taken for C-reactive protein (CRP), albumin, and full blood count (FBC) allowed patients to be grouped by modified Glasgow Prognostic Score (mGPS), and anaemia subtype (haemoglobin (Hb) M < 130 mg/L and F < 120 mg/L, with microcytic anaemia being mean corpuscular volume (MCV) < 80 f/L, and normocytic anaemia with MCV 80–100 f/L). Relationships between these groupings and red cell measures iron status including Hb, MCV, mean corpuscular haemoglobin (MCH) and red cell distribution width (RDW) were examined.ResultsThe combination of increasing T stage and increasing mGPS was associated with lower Hb, lower MCV, lower MCH, higher RDW, and higher prevalence of both microcytic and normocytic anaemia (all p < 0.001). The combination of CRP >10 mg/L and albumin <35 g/L was associated with lower Hb, lower MCV, lower MCH, higher RDW, and higher prevalence of both microcytic and normocytic anaemia (all p < 0.010). At multivariate Cox regression only Hb remained significantly associated with cancer specific (HR 0.98, 95% CI 0.97–0.99, p < 0.001), and overall survival (HR 0.98, 95% CI 0.97–0.99, p = 0.001).ConclusionsThe presence of a host systemic inflammatory response to colorectal cancer was associated with significant perturbation of red cell measure of iron status.     

Management of cancer-related anemia in patients with breast or gynecologic cancer: new insights based on results from the European Cancer Anemia Survey

The incidence, prevalence, and treatment of anemia (hemoglobin [Hb] <12 g/dl) in women with breast cancer and gynecologic cancer were evaluated using data from the European Cancer Anemia Survey (ECAS). Adult patients with newly diagnosed treated or untreated disease, persistent/recurrent disease, and disease in remission were enrolled and followed for up to six chemotherapy cycles or six evaluation points within a 6-month period. At enrollment, 30.4% of breast cancer patients and 49.1% of gynecologic cancer patients were anemic. A significant correlation was shown between low Hb level and poor performance status (World Health Organization criteria) at enrollment for both breast cancer and gynecologic cancer patients. In all, 62.4% of breast cancer patients and 81.4% of gynecologic cancer patients were anemic at some time during the survey. The incidence of anemia, determined in a carefully defined population, was 59.8% for breast cancer patients and 74.8% for gynecologic cancer patients. Despite the high prevalence and incidence of anemia, only 26.3% and 42.7% of patients in the respective groups received anemia treatment. In breast cancer patients, the mean Hb trigger was 10 g/dl for epoetin treatment and 8.6 g/dl for transfusion; corresponding values for gynecologic cancer patients were 10.1 g/dl and 9.1 g/dl. Logistic regression analyses in the overall ECAS population identified five factors as significant and suitable predictors of anemia: lower initial Hb, having lung or gynecologic cancer versus gastrointestinal/colorectal cancer, any other cancer versus gastrointestinal/colorectal cancer, treatment with platinum chemotherapy, and being female. The ECAS data highlight the need for greater awareness of the adverse impact of anemia on cancer patients and for optimal anemia management to ensure maximal patient quality of life.     

Incidence of anaemia in breast cancer patients receiving adjuvant chemotherapy

Anaemia is frequent in breast cancer patients but often remains undiagnosed and untreated. To determine the incidence of anaemia a prospective survey of primary non-metastatic breast cancer patients who received at least four cycles of adjuvant, non-platinum multi-agent chemotherapy was conducted at 47 centres in Austria. Two hundred and forty seven patients were prospectively included between October 1999 and December 1999. Haemoglobin (Hb) levels were determined after surgery and prior to each cycle of chemotherapy. Treatment of anaemia (blood transfusion or epoetin alfa) during the observation period was at the physician's discretion. For the purpose of this study, patients were considered to be anaemic if their Hb was below 12 g/dl. At baseline (after surgery and before the first cycle of chemotherapy), 28.7% of all patients were anaemic. The only significant differentiating factor was the type of surgery. 37.9% of patients who underwent mastectomy were anaemic, whereas only 22.8% of patients who underwent breast conserving surgery were anaemic. Forty two percent of 176 patients with a Hb level of 12 g/dl at baseline developed anaemia during adjuvant chemotherapy. The only factor that significantly influenced the development of anaemia during chemotherapy was the Hb level at baseline. The total incidence of anaemia in patients with primary breast cancer who underwent surgery followed by adjuvant multi-agent chemotherapy was 58.7%. Forty nine patients (20.2%), 48 patients (19.2%) and 48 patients (19.2%) showed a decrease in Hb levels by 1 g/dl, 1–2 g/dl and >2 g/dl, respectively. Only 18.6% of the patients who were found to be anaemic received anaemia treatment. The two most important factors for developing anaemia are the kind of surgery and the Hb level prior to chemotherapy.
