. Background: Guidelines addressing the management of venous
thromboembolism (VTE) in cancer patients are heterogeneous and their
implementation has been suboptimal worldwide. Objectives: To establish a
common international consensus addressing practical, clinically relevant
questions in this setting. Methods: An international consensus working
group of experts was set up to develop guidelines according to an
evidence-based medicine approach, using the GRADE system. Results: For
the initial treatment of established VTE: low-molecular-weight heparin
(LMWH) is recommended [1B]; fondaparinux and unfractionated heparin
(UFH) can be also used [2D]; thrombolysis may only be considered on a
case-by-case basis [Best clinical practice (Guidance)]; vena cava
filters (VCF) may be considered if contraindication to anticoagulation
or pulmonary embolism recurrence under optimal anticoagulation; periodic
reassessment of contraindications to anticoagulation is recommended and
anticoagulation should be resumed when safe; VCF are not recommended for
primary VTE prophylaxis in cancer patients [Guidance]. For the early
maintenance (10 days to 3 months) and long-term (beyond 3 months)
treatment of established VTE, LMWH for a minimum of 3 months is
preferred over vitamin K antagonists (VKA) [1A]; idraparinux is not
recommended [2C]; after 36 months, LMWH or VKA continuation should be
based on individual evaluation of the benefit-risk ratio, tolerability,
patient preference and cancer activity [Guidance]. For the treatment
of VTE recurrence in cancer patients under anticoagulation, three
options can be considered: (i) switch from VKA to LMWH when treated with
VKA; (ii) increase in LMWH dose when treated with LMWH, and (iii) VCF
insertion [Guidance]. For the prophylaxis of postoperative VTE in
surgical cancer patients, use of LMWH o.d. or low dose of UFH t.i.d. is
recommended; pharmacological prophylaxis should be started 122 h
preoperatively and continued for at least 710 days; there are no data
allowing conclusion that one type of LMWH is superior to another [1A];
there is no evidence to support fondaparinux as an alternative to LMWH
[2C]; use of the highest prophylactic dose of LMWH is recommended
[1A]; extended prophylaxis (4 weeks) after major laparotomy may be
indicated in cancer patients with a high risk of VTE and low risk of
bleeding [2B]; the use of LMWH for VTE prevention in cancer patients
undergoing laparoscopic surgery may be recommended as for laparotomy
[Guidance]; mechanical methods are not recommended as monotherapy
except when pharmacological methods are contraindicated [2C]. For the
prophylaxis of VTE in hospitalized medical patients with cancer and
reduced mobility, we recommend prophylaxis with LMWH, UFH or
fondaparinux [1B]; for children and adults with acute lymphocytic
leukemia treated with l-asparaginase, depending on local policy and
patient characteristics, prophylaxis may be considered in some patients
[Guidance]; in patients receiving chemotherapy, prophylaxis is not
recommended routinely [1B]; primary pharmacological prophylaxis of VTE
may be indicated in patients with locally advanced or metastatic
pancreatic [1B] or lung [2B] cancer treated with chemotherapy and
having a low risk of bleeding; in patients treated with thalidomide or
lenalidomide combined with steroids and/or chemotherapy, VTE prophylaxis
is recommended; in this setting, VKA at low or therapeutic doses, LMWH
at prophylactic doses and low-dose aspirin have shown similar effects;
however, the efficacy of these regimens remains unclear [2C].
Special situations include brain tumors, severe renal failure (CrCl < 30
mL min-1), thrombocytopenia and pregnancy. Guidances are provided in
these contexts. Conclusions: Dissemination and implementation of good
clinical practice for the management of VTE, the second cause of death
in cancer patients, is a major public health priority.
