Pharmacogenetics
• Pharmacogenetics may influence the
development of hematologic toxicity
• Metabolic processes for drug
inactivation are polymorphic
• Ex: polymorphic deficiency of
dihydropyrimidine dehydrogenase
results in increased toxicity of 5-FU,
including hematologic toxicity
A few chemotherapeuty agents result
in virtually no myelosuppression

• The myelosuppressive effects of paclitaxel
consist primarily of granulocytopenia, with an
increase in the incidence and severity of
neutropenia observed with increasing doses,
• Identical doses of paclitaxel are markedly less
myelosuppressive when delivered by 3-hr than
by 24-hr infusion,
• Neutropenia is not related to paclitaxel’s peak
concentration or to the AUC but rather to the
duration that the plasma concentration is
aboce a certain threshold (>=0,05 µmol/L).

pas de foyer ») elle atténue la
présentation clinique (« simple fièvre),

Routine use of CSFs for primary prophylaxis of FN for any common disease in previously
untreated patients is not justified,
The available data indicate that, with a sufficiently high incidence of FN ( 40%), there is
strong evidence for the primary administration of CSFs to reduce hospitalization for
antibiotic administration.
Secondary prophylaxis: physicians should consider chemotherapy dose reduction after
neutropenic fever or severe or prolonged neutropenia after the previous cycle of
treatment,
CSFs should not be routinely used for patients with neutropenia who are afebrile,
CSFs should not be routinely used as adjunct therapy for the treatment of
uncomplicated fever and neutropenia. Uncomplicated fever and neutropenia are defined
as follows: fever of 10 days in duration; no evidence of pneumonia, cellulitis, abscess,
sinusitis, hypotension, multiorgan dysfunction, or invasive fungal infection; and no
uncontrolled malignancies,
Certain patients with fever and neutropenia are at higher risk for infection-associated
complications and have prognostic factors that are predictive of poor clinical outcome.
The use of a CSF for such high-risk patients may be considered, but the benefits of a
CSF in these circumstances have not been proven. These factors include profound (ANC
< 100/µL) neutropenia, uncontrolled primary disease, pneumonia, hypotension, multiorgan
dysfunction (sepsis syndrome), and invasive fungal infection. Age greater than 65 years
and posttreatment lymphopenia may also be high-risk factors but have not been
consistently confirmed by multicenter trials.

Myeloid Growth Factors in Cancer Treatment version 1.2005
• The NCCN panel members recommend
the routine use of CSFs for high-risk
(>20%) patients to prevent the
development of FN in patients
receiving treatment with curative
intent, adjuvant therapy, or
treatment expected to prolong
survival or to improve QOL.

Antibacterial prophylaxis after chemotherapy for
solid tumors and lymphomas.
Patients who were receiving cyclic chemotherapy for solid tumors or lymphoma and who
were at risk for temporary, severe neutropenia (fewer than 500 neutrophils per cubic
millimeter).
Patients were randomly assigned to receive either 500 mg of levofloxacin once daily
or matching placebo for seven days during the expected neutropenic period.

One hundred seven of the 1,051 patients of the CLB-1996 cohort (10%) experienced
SARRT.
In univariate analysis:
– female sex,
– performance status greater than 1,
– hemoglobin level less than 12 g/dL before chemotherapy on day 1 (d1),
– d1 lymphocyte count <= 700/µL significantly correlated with the risk of SARRT.
Using logistic regression:
– d1 hemoglobin level less than 12 g/dL (OR = 14.0; 95% CI, 7 to 30),
– performance status greater than 1 (OR = 2.2; 95% CI, 1.4 to 3.5),
– d1 lymphocyte count <= 700/µL (OR = 1.7; 95% CI, 1.1 to 2.6) were identified as
independent risk factors for SARRT.
These three factors were given arbitrary risk coefficients of 3, 1, and 1 respectively,
and a risk score for each individual patient was obtained by adding the coefficients.
The calculated probability of RBC transfusions was 30% for patients with a score 4,
and 11%, 4%, and 1% in patients with a score of 2 or 3, 1, and 0 respectively.

Cohort of the 1,051 patients (CLB 1996) treated with chemotherapy
In univariate analysis:
– performance status (PS) greater than 1,
– platelet count less than 150,000/µL at day 1 (d1) before the initiation of
chemotherapy,
– d1 lymphocyte count <= 700/µL,
– d1 polymorphonuclear leukocyte count less than 1,500/µL,
– and the type of chemotherapy (high risk v others) were significantly associated
(P < .01) with an increased risk of severe thrombocytopenia requiring platelet
transfusions.
Using logistic regression:
– d1 platelet count less than 150,000/µL (OR, 4.3; 95% CI, 1.9 to 9.6),
– d1 lymphocyte counts <= 700/µL (OR, 3.37; 95% CI, 1.77 to 6.4),
– the type of chemotherapy (OR, 3.38; 95% CI, 1.77 to 6.4),
– and PS greater than 1 (OR, 2.23; 95% CI, 1.22 to 4.1) were identified as independent
risk factors for platelet transfusions.
The observed incidences of platelet transfusions were 45%, 13%, 7%, and 1.5% for
patients with 3, 2, 1, or 0 risk factors, respectively. This model was then tested in
3 groups of patients treated with chemotherapy used as validation samples:
