• Increasing the prophylactic doses of LMWH may be appropriate in morbidly obese patients (body mass index 40 kg/m
•
Laboratory monitoring of LMWH could be
considered in patients with morbid obesity (weight >190 kg). Peak anti-Xa levels should be drawn 4 hours after sub-Q injection of LMWH; however, the efficacy and safety of dose adjustments have not been established.
Be aware of syringe size of LMWH when
• choosing a dose in obese patients. Using once-daily enoxaparin may not be practical in patients >100 kg due to available doses and required number of syringes to use, and it did not appear as efficacious as twice-daily dosing in the Merli study that led to market approval.

Patients with Malignancy
•
VTE in patients with malignancy is secondary to a hypercoagulable state, and patients with cancer have an increased risk of VTE especially in the first few months after diagnosis. Although not all malignancies are associated with throm bosis, the overall risk of VTE is increased 7-fold in patients with a malignancy and up to 28-fold in certain malignancies.
•
VTE is the second most common cause of mortality in patients with cancer.
•
Treatment guidelines for VTE in patients with cancer are available through multiple national organizations (National Comprehensive Cancer Network [NCCN]/American Society of Clinical Oncology [ASCO]/American College of Chest Physicians [ACCP]). The guidelines generally recommend LMWH for the initial treatment of VTE in patients with cancer.
•
Extended duration of therapies are generally preferred over shorter durations of therapy at least until cancer is in remission or surgically removed.

Caveats for Consideration
•
Dalteparin has demonstrated significant reductions in VTE.
•
LMWH trials have showed varying results in bleeding rates and mortality.
•
The trial for enoxaparin in cancer was stopped for enrollment reasons. Several trials have demonstrated inferior performance of once-daily enoxaparin for acute VTE treatment, so the dosing regimen above is extrapolated from the dalteparin trials.
•
Subset analysis of DOACs has demonstrated lower rates of VTE and bleeding compared to VKA; however, these have been nonsignificant changes.
•
The Hokusai VTE Cancer trial assessing edoxaban and dalteparin showed non-inferiority in the composite outcome, but the edoxaban group failed to show a significant reduction in VTE while leading to a significant increase in bleeding, especially GI bleeding.
80
• LMWH are the recommended agents to treat VTE in patients with malignancy, as they have demonstrated reductions in VTE compared to VKA.
• Patients who receive PEG asparaginase may experience a severe drop in antithrombin. If they develop a VTE, they may not respond to an antithrombin dependent anticoagulant until antithrombin recovers. In such situations, a DOAC may need to be considered.
• In patients with Trousseau syndrome (spontaneous or recurrent venous thrombosis),
274 Anticoagulation Therapy
https://t.me/med1917
heparin is the preferred anticoagulant of choice (not VKA or DOACs) and should be continued indefinitely because stopping for even 1 day can result in recurrence of thrombosis.
•
The use of VKAs in patients with malignancy
may have several limitations including drug interactions with chemotherapeutic medications, altered absorption and pharmacokinetics, inability to take secondary to nausea, and need for increased monitoring in patients with liver metastasis.
• Practical issues in the long-term use of LMWH include cost of the medication, ability of the patient to administer parenteral or subcutaneous medications, possible need for monitoring of medication in certain patients, and the patient’s quality of life.
DOAC agents have not been directly compared
• to LMWH or to VKA specifically in patients with malignancy, however, subset analysis of several DOAC trials have assessed their role in this patient population. In general, DOACs have demonstrated similar rates in VTE recurrence and bleeding compared to VKA; however, many clinicians feel cancer-specific studies are needed and that comparisons to long-term LMWH are needed. In addition, the effects of the DOACs on the chemotherapy regimen should also be considered.
