TNFa (1)
TNFa
 decrease of GATA-1 mRNA
decrease of GATA-1 protein
induces NF-kB binding activity
M. DICATO
TNFa (2)
TNFa  inhibits induction of erythroid differentiation
 inhibits expression of erythroid specific genes:
y-globin and EpoR
 affects induced transcription factor GATA-1
 Blocks binding of GATA-1 to its DNA sequence
Conclusion: TNFa acts at several levels of the regulation of
erythroid genes, in particular GATA- 1.
Inhibition of GATA-1 correlates to increased NF-kB activity
M.Dicato, L. Plawny, M. Diederich: Ann. Oncol. 2010,
Fig. 3 – Pathophysiology of anemia. Tumor cells act on erythrocytes through macrophages by cytokine release, which leads
to impaired erythropoiesis. Released cytokines can affect BFU-E and CFU-E proliferation, iron utilization and Epo
production. TNFa can also affect erythrocyte half-life. TNFa, tumor necrosis factor alpha; IFN, interferon; IL, interleukin;

Suggestions of adverse cancer-related outcomes
• Demand on blood supply would intensify

Colorectal resection and blood transfusions:
• 0,97% of pts. developed VTE while in hospital
• increased risk of VTE in women, not in men
Blood transfusions are associated
with a high risk of thrombosis
• Red blood cell (RBC) transfusions were associated
with a high risk of venous and arterial
thrombotic events
– Patients receiving RBC transfusions
 7.2% developed venous thromboembolism
 5.2% developed arterial thromboembolism (values significantly
greater than remaining study population; p<0.001)
• RBC transfusions were associated with increased
risk of mortality in hospitalised patients with cancer

Red Blood Cell (RBC) Transfusion
Indications1
 Acute blood loss
– Loss of circulating blood volume
– Concentration of haemoglobin
– Further bleeding resulting from abnormal haemostasis
 Anaemia in critical care
 Perioperative transfusion
 Chronic anaemia including chemotherapy-induced anaemia
Compatibility2
 Must be ABO and Rh compatible
 Antibody detection and crossmatch required
Shelf life3
 Refrigerated red blood cells: 42 days
 Once opened: 24 hours at 1–6°C2
Administration2
 Unless otherwise indicated by the patient's clinical condition, rate
of infusion no greater than 2 mL/min for the first 15 min
 One unit usually takes 45–90 minutes to infuse
 Transfusion should not take longer than 4 hours due to risk of
bacterial proliferation at room temperature

Risk/ Benefit of Anemia Treatment
• VTE Risk in Anemia Treatment :

on Hb level targeted (JAMA, 2008)
– TRANSFUSION and VTE Risk
( Arch Int. Med 2008 : HR: 1.34)
Epo proangiogenic effect
• In human glioma: J. Neuro-oncology 2011, 102:
51-58
• In melanoma: Int. J. Exp. Pathol. 2010, 91-495-99
Antagonistic effect of Epo(E) on treatment
with Trastuzumab(T) in Breast Cancer
• Co-expression of EpoR and EGFR-2 (Her-2) in a
significant percentage of human BC samples.
• Concurrent treatment of the cells with E and T
reduced response to T both in vitro and in vivo.
Jak-2 mediated activation of Src and of PTEN
could be a mechanism thru which E antagonizes T
and reduces clinical response.
• Retrospective study: 37 pts with both drugs
compared to 74 pts only T: better PFS and OS in
the non E group.
Cancer Cell 2010, 18: 423-35
Hematologica 2010, 95:1823
• Epo enhances pro-inflammatory activity and
function of macrophages
• Dendritic cells express Epo-R and Epo increases
survival and function
• Macrophages may produce functional EPO
• EPO may attenuate inflammatory response,
delaying appearance of TNF and decreasing IL-6 and TNF
• Macrophages can be target for EPO
• Epo improves wound healing

Conclusions
• The effects of ESA QW are enhanced in
patients receiving IV iron supplementation
– Haematopoietic response rates of patients in the
per-protocol population receiving ESA QW with
or without IV iron were 92.5% vs 70%,
(p=0.0033) respectively
• The safety profile of ESA QW was comparable
between study arms

IV Iron Use in Cancer Patients
• Summary of clinical findings
–
–
–
–
Generally well tolerated
Increased rate of Hb response
Reduction of RBC need
IV iron supplementation optimizes response to ESA therapy in
patients with chemotherapy induced anemia independent of Fe
parameters
• Limitations
–
–
–
–
Heterogeneous inclusion criteria
Identification of patients likely to benefit from IV iron unclear
No long-term follow-up data for IV iron in cancer patients
No data showing that the combination of an ESA with iron is safer
than ESA alone
– “IV-iron only” studies still to be performed
• Guideline Recommendations

Main advantages/ concerns
Blood transfusions
• Immediate correction of anaemia,1 however
associated risk level is still debated
Oral iron
• I.v. iron superior to oral iron1
ESA without iron
• Reduction of transfusion requirements2–4
• Improvement in QoL2–5
• 50–70% response rate2,6–8
ESA with oral iron
• Same advantages as ‘without oral iron’, however
more side effects1,5,9
ESA with i.v. iron
•

•
•
Increased patient response rate of up to 90%10–14
Correction of FID10–14
Reduction of transfusion requirements10
Improved QoL11

Generic Substitution
• Highly effective: In USA each 1% increase in
generic prescribing reduces drug cost by 1.32
billion $ annually.
• In UK average cost of a generic is ¼ of the
original brand drug
• In generic substitution of the top 10
prescribed drugs in E.U. could release savings
of 20-48% to reinvest in improved patient care
Biosimilar Substitution

Biologic drug sales in US in 2010: >60 billion $
