What is GCSF?
• GCSF stands for ‘Granulocyte Colony Stimulating Factor’
• GCSF and Granulocytes are produced by endothelium,
macrophages and other immune cells. There are 3 types of
granulocyte
Neutrophil
Eosinophil
Basophil
• GCSF has 2 structural forms; with 174 & 180 amino acids
• GCSF was first discovered while testing Heamopoetic Stem
Cells (HSCs) for colony stimulating substances.

Biology
• In order to interact with the cell, there must be GCSF
receptors present
• The GCSF receptor is present on precursor cells in
Bone Marrow
• In response to GCSF, cell signalling mechanisms
instruct the cell to proliferate and differentiate into
mature granulocytes
• Main use is for
• HSC mobilisation
• Decreasing incidence of neutropenia
How does it work?
GCSF binds to surface receptors of neutrophil precursors and
mature neutrophils stimulating
• Proliferation
• Differentiation
• Commitment, and
• End cell function
Approved uses

Standards in Haematology

With chemotherapy
Acute Myeloid Leukemia
(AML)
The routine use of CSF is recommended
after consolidation chemotherapy (level
Ib, Grade A). CSF is recommended after
induction if it is appropriate to reduce
hospital stay or antibiotic usage.
Acute Lymphoblastic
Leukemia (ALL)
Myelodysplastic Syndrome
(MDS)
GCSF is indicated to reduce the severity
of neutropenia following intensive
phases of therapy (level Ib, grade A).
CSF’s are indicted to reduce the severity
of neutropenia in patients receiving
intensive chemotherapy (level Ib, grade
A). CSF’s are also recommended on an
intermittent basis for patients with
neutropenia and infection (level IV,
grade C), but continuous prophylactic
use is not routinely justified.
With chemotherapy
Aplastic anaemia
There is insufficient evidence to make
any general recommendations and
hence patients should be given CSF’s
only on an individual therapeutic trial
basis (level IV, grade C).
Bone marrow failure
syndromes
Malignant lymphomas
GCSF is recommended when
improvement of neutrophil count is
appropriate (level III, grade B).
There is evidence to support the
routine use of CSF’s to reduce the
incidence of infection, chemotherapy
delay and hospitalization especially
when the risk of febrile neutropenia
exceeds 40% (level Ia, grade A). There is
also emerging evidence of improved
survival with GCSF-supported dose
intensification in elderly patients with
high-grade NHL (level Ib, grade A). At
present, this evidence is insufficient to
justify a change in policy in all patients
with lymphoma, but elderly patients
may benefit from G-CSF support.
Mobilisation
• G-CSF’s are recommended by the BSCH for the mobilisation of
peripheral blood progenitor cells (PBPC)
• Dose is calculated by weight; reference tables are available in
Mount Vernon Guidelines 2010.
• GCSF can be used alone or in conjunction with chemotherapy.
• Biosimilars not recommended by EBMT 2011

Instructions
How do I prepare my Neupogen injection?
Before you inject Neupogen you must do the following:
1 To avoid bending the needle, gently pull the
cover from the needle without twisting as shown
in pictures 1 and 2.
2 Do not touch the needle or push the plunger.
• You may notice a small air bubble in the pre-filled syringe.
• You do not have to remove the air bubble before injecting.
Injecting the solution with the air bubble is harmless.
3 You can now use the pre-filled syringe.
The best places to inject are the top of your
thighs and the abdomen. If someone else is
injecting you, they can also use the back of your
arms.
You may change the injection site if you notice
the area is red or sore.

GCSF Common Side Effects
Bone pain
Red itchy skin
Fluid retention
Fever and chills
Plerixafor
• Originally for HIV and manufactured by Genzyme
• Works as a HSC mobiliser
• Licensed for lymphoma and myeloma poor mobilisers in
conjunction with GCSF
Dose
Plerixafor (Mozibil™) ADULT over 18 years, 240 micrograms/kg daily 6-11 hours before initiation of apheresis; usual duration 2-4
days (max. 7 days) by subcutaneous injection. Mozobil injection supplied as 1.2mL-vial
Indications
Peripheral Blood Stem Cell Mobilisation, with GCSF in patients with Lymphoma or Myeloma
Instructions for injecting Plerixafor
You will most likely receive your Plerixafor injections at your transplant center or hospital, depending on hours of operation.
Plerixafor will be given to you as an injection under your skin (this is called a subcutaneous injection).
A member of your healthcare team will inject the medication into a fleshy part of your body (such as your hip or leg).
Plerixafor is given in combination with GCSF. Your doses of GCSF should be given each day starting 4 days before your first evening
dose of Plerixafor and every morning you are scheduled for a session of apheresis.
