Page 4: Developments in the management of cancer-associated ......Cancer-Associated Thrombosis (CAT) Prevalence and Burden •VTE is a major complication of cancer and a leading cause of death

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

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

Patients with luminal GI cancers with an intact primary

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
