Summary
• New drugs in Oncology and VTE risk
• Primary thromboprophylaxis in ambulatory setting
• New risk assessment models and molecular risk factors
• DOACs & CAT treatment (ready for prime time?)
Cancer-Associated Thrombosis (CAT)Prevalence and Burden
• VTE is a major complication of cancer and a leading cause of death among cancer patients
• Approximately 20% of all VTE cases occur in patients with cancer
• VTE affects up to 20% of patients with cancer before death and has been reported in up to 50% of cancer patients at the time of postmortem examination
• CAT has important clinical and economic consequences, including
– Increased morbidity resulting from hospitalization and anticoagulation use
– Bleeding complications
– Increased risk of recurrent VTE
– Cancer treatment delays and stop
– Finally increased costs

– Variable off-target effects may also play a role in VTE risk
• Primary thromboprophylaxis?

Ben-Aharon Meta-analysisLung & Pancreas Cancer
Primary thrombo-prophylaxis in solid malignancies – a meta-analysis 1235
cancer LM WH reduced the RR for VT E even fur-
ther [0.28 (95% CI 0.16 – 0.49) for pancreatic can-
cer] and [0.43 (95% CI 0.26 – 0.71) for lung cancer] .
LM WH had no effect on survival in meta-analysis
of all tr ials.
Based on our meta-analysis the NNT to prevent
one symptomatic VT E is 50 (95% CI 33 – 100).
Among lung cancer patients the NNT to prevent one
VT E is 33 (95% CI 25 – 100) and in pancreatic cancer
the NNT to prevent one VT E is 10 patients (95% CI
7 – 16), indicating a substantial benefi t for LM WH in
this subpopulation. T he rate of serious adverse events
was low, with the number needed to harm (NNH)
being 100 (95% CI 50 – very large number) for clini-
cally relevant bleeding. T he RR for major bleeding
events was not greater compared with the control arm
and neither the rate of thrombocytopenia. We could
not infer based upon the analysis whether a specifi c
LM WH exhibit superior results compared with other
agents of this group, it is therefore probably safe to
assume there is a class effect.
T he rationale for primary thromboprophylaxis
in cancer patients arises from the marked risk of can-
cer-associated VT E. Population-based case-control
studies indicate a two-year cumulative incidence of
0.6 – 7.8%, depending on the population studied
[28,29]. T he risk for VT E depends profoundly on the
primary site of cancer, whereas pancreatic, gastric and
lung cancers confer the highest risk to develop VT E
[30]. Lung and cardiac comorbidities which are
frequent in lung cancer patients increase the risk of
VTE by 20% [31,32]. Former studies indicate that the
incidence of VTE is highest within the fi rst six months
of commencing the anti-cancer treatment [2].
Our meta-analysis did not show a survival advan-
tage. Several studies have indicated that selected pop-
ulations may gain a survival advantage from LM WH
prophylaxis, whereas the LM WH benefi t was most
apparent among patients with a better prognosis. Some
other considerations that may impact survival analysis
include the short length of follow-up: in some of the
studies in a subgroup analysis, the good-prognosis
group of patients experienced a superior survival with
LM WH [18,19]. Another determinant is the effect of
LM WH in different tumor types and disease stages.
T he majority of studies included in the meta-analysis
encompass a variety of tumor types whereas the bio-
logical role of LM WH may differ in distinctive cancers.
Due to the main role of coagulation pathways in pan-
creatic and lung cancer, the potential benefi t of con-
comitant administration of LM WH may be enhanced
in these cancers, as we have shown in this meta-anal-
ysis in terms of VTE reduction in these entities.
Several limitations of this analysis must be acknowl-
edged. The heterogeneity of cancer types and disease
stages in some of the studies may attenuate the impact
phylaxis to cancer patients concomitantly with
standard chemotherapy signifi cantly reduces the risk
for symptomatic VT E, any VT E and PE, while the
risk for major bleeding is not signifi cantly increased.

Primary thromboprophylaxis outpatient setting
Limitations to expand ambulatory primary thromboprophylaxis:
No impact in OS
Low event rate in control arm (<10%) & high NNT with &without KS
No QoL analysis
High cost (cost effectiveness analysis )
To expand thromboprophylaxis, definitely we have to improve STRATIFICATION:
• Selection of patients (control arm VTE incidence <10%): better RAM, > KS
• Clinical detection of high-risk of bleeding: lack of RAM of bleeding

Final treatment recommendation should be made after shared decision making with patients regarding a potential reduction in recurrence
but higher bleeding rates with specific NOACs, incorporating patient preferences and values
Anticoagulant Therapy Suggest Use of
Specific NOACs
(edoxaban or rivaroxaban)
In patients with low risk of bleeding and no drug-drug
interactions with current systemic therapy
LMWH
In patients with high risk of bleeding, including
Patients with luminal GI cancers with an intact primary
Patients with cancers at risk of bleeding from the GU
tract, bladder, or nephrostomy tubes
Patients with active GI mucosal abnormalities such as
duodenal ulcers, gastritis, esophagitis, or colitis

DOACs: New treatment option but, maybe not the right drug for all cancer patients…my thoughts
• High-risk bleeding
– Mucosa involvement or primary tumor in place (not resected)
– Concomitant treatment with antiangiogenics (antiangiogenic therapy increase the risk of bleeding: bevacizumab, aflibercept, etc.)
– Tumor invading great vessels (lung cancer and vena cava/aorta/pulmonary artery…)
– Thrombocytopenia, etc.
• Concomitant treatment with other drugs (interactions, clinically relevant?)
• Impaired oral intake: obstructive tumors, nauseas&vomiting, etc.
• Malabsorption: extensive GI resection (cytoreductive surgery), etc.
• Liver impairment: extensive liver mets, etc.
• Mucositis (treatment toxicity) & benign diseases of the GI mucosa
