2. Prevalence of anaemia in cancer
Anaemia is the most common haematological
disorder in patients with cancer
– approximately 20%–60% of patients with
cancer will have anaemia at presentation
Treatment for cancer can induce or exacerbate
anaemia: the extent of this varies according to the
type of tumour and treatment

6. Cancer-related anaemia in Europe:
Type of Tumor
Anaemia tended to be mild-to-moderate
(10–12 g/dL) in solid tumours
Anaemia tended to be more severe in
haematological malignancies (<10 g/dL)
There were some between-country differences in
Hb levels in different malignancies

12. Causes of anaemia in patients with cancer:
Other treatment-related factors
Radiotherapy
– has direct effects on bone marrow suppression
– can impair appetite and so reduce vital nutrient
uptake
– has been shown to induce or exacerbate anaemia
in 54% of patients with solid tumours1
Anaemia may also result from blood loss due to
surgery
1Harrison L, et al. Semin Oncol. 2001;2(suppl 8):54-59.
13. Signs and symptoms of anaemia
Central nervous system
Debilitating fatigue
Dizziness, vertigo
Depression
Impaired cognitive function
Immune system
Impaired T-cell and
macrophage function
Cardiorespiratory system
Exertional dyspnoea
Tachycardia, palpitations
Cardiac enlargement,
hypertrophy
Increased pulse pressure,
systolic ejection murmur
Risk of life-threatening cardiac
failure
Gastro-intestinal system
Anorexia
Nausea
Genital tract
Menstrual problems
Loss of libido
Vascular system
Low skin temperature
Pallor of skin, mucous
membranes and conjunctivae
Adapted from Ludwig H. Semin Oncol. 1998;25(suppl 7):2-6.
15. Anaemia adversely affects
quality of life (QOL)
Fatigue is the most commonly reported clinical
manifestation of anaemia in patients with cancer
– 78% of patients with cancer suffer fatigue1
Fatigue is not relieved by sleep or rest
At Hb levels <12 g/dL, fatigue increases significantly

18. Anaemia is an adverse prognostic
factor in patients with cancer
Increasing evidence suggests that anaemia adversely
affects survival in patients with cancer
Anaemia and thrombocytopenia at diagnosis strongly
predicted for poor outcome in patients with chronic
lymphocytic leukaemia1
Anaemia at diagnosis was an independent adverse
prognostic factor in patients with Hodgkin’s disease2
or NHL3
1Binet J, et al. Cancer. 1981;48:198-206.
2Hasenclever D, et al. N Engl J Med. 1998;339:1506-1514.
3Moullet I, et al. Ann Oncol. 1998;9:1109-1115.
19. Anaemia as an independent prognostic
factor: Literature review
A literature review of 60 clinical studies assessed
the effects of anaemia on survival in patients with
a variety of solid tumours and haematological
malignancies1
Anaemia increased the relative risk of death by
between 19% and 75%, depending on the
malignancy
1Caro J, et al. Cancer. 2001;91:2214-2221.
20. Anaemia is associated with reduced survival in
patients with non-Hodgkin’s lymphoma

I pazienti affetti da NSCLC che hanno mantenuto
livelli di Hb > a 12 gr/dL hanno avuto una maggiore
sopravvivenza
Waters JS et al., J Clin Oncol 2002;15: 601-3
22. Tumour hypoxia potentiates tumour
progression (cont’d)
Hypoxia may stimulate tumour growth by induction of
– urokinase plasminogen activator (uPA)
• leads to degradation of the tumour extracellular
matrix and subsequent metastatis1
– vascular endothelial growth factor (VEGF) secretion
• promotes angiogenesis tumour growth and
metastasis2
1Molls M. Proc 1st International Conference on Erythropoietin in Radiation
Oncology, Freiburg, Germany, June 1999.
2Dunst J, et al. Strahlenther Onkol. 1999;175:93-96.
23. Tumour hypoxia potentiates tumour
progression
The impact of anaemia on the survival of patients with
cancer may be due to low tumour levels of oxygen
Experimental data show that tumour hypoxia leads to
– tumour invasiveness
– metastatic potential
– resistance to cancer therapy1
Hypoxia may also promote the selection of aggressive
tumour phenotypes with reduced apoptotic potential
1Höckel M, et al. Cancer Res. 1999;59:4525-4528.
24. Anemia e sopravvivenza
Il decremento della Hb durante il trattamento
CT/RT per NSCLC stadio III si correla in modo
significativo alla sopravvivenza
MacRae R. et al; Radiother Oncol. 2002;64(1):37-40
25. Increasing serum Hb levels may improve
survival in patients with cancer receiving
CHT
In a placebo-controlled trial of 375 anaemic patients receiving non-
platinum–based chemotherapy for a variety of malignancies,
administration of recombinant EPO (rHuEPO) led to a:
– significant increase in Hb levels (P <0.001)
– significant decrease in transfusion requirements (P = 0.0057)
– significant improvement in QOL (P <0.01)
– trend towards an increase in survival (12-month estimated rates:
60% vs 49% for placebo)*
Littlewood T, et al. J Clin Oncol. 2001;11:2865-2874.

30. UK audit of RBC transfusions and anaemia
in patients with cancer (cont’d)
Approximately one-third of patients required a RBC
transfusion
The following factors were significantly associated
with a higher incidence of RBC transfusion
– pretreatment Hb <11 g/dL vs no anaemia
– lung/ovarian vs breast/testicular tumours
– metastatic vs non-metastatic disease
(for breast testicular and ovarian cancers)
Barrett-Lee P, et al. Br J Cancer. 2000;82:93-97.

32. RBC transfusions
Until recently RBC transfusion was the therapy of choice for
symptomatic anaemia
RBC transfusion is still appropriate for patients requiring
– rapid correction of Hb, eg, chronic symptomatic anaemia
– an increase in blood volume, eg, severe haemorrhage
However
The effects of RBC transfusion are short-lived
RBC transfusion does not address the underlying process of anaemia

Bohlius, Lancet 2009
Tutti i pazienti trattati con ESA
(popolazione globale anche fuori indicazione)
40. Alcuni studi hanno rilevato una tendenza verso una maggiore
sopravvivenza nel gruppo che riceveva ESA rispetto al gruppo placebo
(obiettivo secondario).
Si è quindi sviluppato un filone di ricerca indirizzato alla valutazione di
un possibile beneficio del trattamento con ESA in termini di
sopravvivenza
Razionale:
• la condizione anemica può peggiorare la prognosi del paziente
oncologico (ipo-ossigenazione tissutale ridurrebbe l’efficacia CHT/RT)
Farmaci che riescono a incrementare i livelli di Hb potrebbero avere
un effetto benefico anche sui i livelli di ossigenazione tessutale,
aumentando quindi la risposta alla CHT/RT.
