  • ESSENTIAL study 2009

– Among 1046 patients undergoing high risk cancer surgery, <50% utilisation of extended TP

  • Cancer Surgery Study 2011

– Among 252,950 cancer surgeries 46% received TP

  • CSSANZ Survey 2012

– Among 128 colorectal surgeons, 54% prescribe TP after hospital discharge. Lack of data, absence of recommendations and logistical issues prevent use in the neoadjuvant and post-discharge settings.

  • ALTG Survey 2013

– Among 157 lung cancer clinicians 91% reported access to institutional guidelines yet

  • nly 65% included risk stratification and 2% had recommendations for ambulatory

care settings.

  • Patient survey 2010

– Among 190 cancer patients, 53% were unaware of the risk of TE yet 86% were willing to receive oral and 46% parenteral prophylaxis

patients (= all cancer patients)

  • Treatment of VTE – LMWH/UFH agents of choice; avoid

novel agents at this time

  • Outpatient treated MM with thal/len – indicated

(inconsistency/ambiguity in agent)

  • Extended P-TP for high risk surgical patients

TP Ambulatory Chemotherapy (excl. then/len)

Guideline Recommendation International Consensus 2013

  • In patients receiving chemotherapy, prophylaxis is not recommended routinely [Grade 1B].
  • Primary pharmacological prophylaxis of VTE may be indicated in patients with locally advanced or

metastatic pancreatic cancer treated with chemotherapy and having a low bleeding risk [Grade 1B].

  • Primary pharmacological prophylaxis of VTE may be indicated in patients with locally advanced or

metastatic lung cancer treated with chemotherapy and having a low bleeding risk [Grade 2B]. ASCO Update 2013

  • Routine pharmacologic thromboprophylaxis is not recommended in cancer outpatients.
  • Based on limited RCT data, clinicians may consider LMWH prophylaxis on a case-by-case basis in

highly selected outpatients with solid tumors receiving chemotherapy. ACCP 9th Ed 2012

  • In outpatients with cancer who have no additional risk factors for VTE, we suggest against routine

prophylaxis with LMWH or LDUH (Grade 2B) and recommend against the prophylactic use of vitamin K antagonists (Grade 1B ESMO 2011

  • Prophylaxis in cancer patients receiving adjuvant chemotherapy and/or hormone therapy is not

recommended [I, A].

  • Extensive, routine prophylaxis for advanced cancer patients receiving chemotherapy is not

recommended, but may be considered in high-risk ambulatory cancer patients [II, C]. SISET 2012

  • Pharmacological prophylaxis is not routinely recommended in patients undergoing chemotherapy or

radiotherapy or hormonal therapy (grade C) except for:

  • Patients with lung or gastrointestinal cancer should receive nadroparin (3,800 U anti-FXa daily) for

no more than 4 months (grade A)

TP Major Surgery

Guideline Recommendation International Consensus 2013 Use of LMWH once a day or a low dose of UFH three times a day is recommended to prevent postoperative VTE in cancer patients; pharmacological prophylaxis should be started 12–2 h preoperatively and continued for at least 7–10 days; there are no data allowing conclusions regarding the superiority of one type of LMWH over another [Grade 1A]. ASCO Update 2013 Patients undergoing major cancer surgery should receive prophylaxis, starting before surgery and continuing for at least 7 to 10 days ACCP 9th Ed 2012 No duration specified Suggest LMWH over no prophylaxis[2B] Suggest LDUH over no prophylaxis[2B] ESMO 2011 For patients having a laparotomy, laparoscopy, thoracotomy or thoracoscopy lasting >than 30 min, consider s.c. LMWH for at least 10 days postoperatively.

9th November 2014 Management of Thrombosis in the Cancer Patient 68

Extended TP High Risk Surgery

Guideline Recommendation International Consensus 2013 Extended prophylaxis (4 weeks) to prevent postoperative VTE after major laparotomy in cancer patients may be indicated in patients with a high VTE risk and low bleeding risk [Grade 2B]. ASCO Update 2013 For high-VTE-risk patients undergoing abdominal or pelvic surgery for cancer who are not otherwise at high risk for major bleeding complications, we recommend extended-duration pharmacologic prophylaxis (4 weeks) with LMWH over limited-duration prophylaxis (Grade 1B) . ACCP 9th Ed 2012 For high-VTE-risk patients undergoing abdominal or pelvic surgery for cancer who are not otherwise at high risk for major bleeding complications, we recommend extended-duration pharmacologic prophylaxis (4 weeks) with LMWH over limited-duration prophylaxis (Grade 1B) . ESMO 2011 Cancer patients undergoing elective major abdominal or pelvic surgery should receive in hospital and post-discharge prophylaxis with s.c. LMWH for up to 1 month after surgery [I, A].

Agent of choice acute VTE

Guideline Recommendation International Consensus 2013 LMWH is recommended for the initial treatment of established VTE in cancer patients [Grade 1B]. Fondaparinux and UFH can be also used for the initial treatment of established VTE in cancer patients [Grade 2D]. ASCO Update 2013 LMWH is preferred over UFH for the initial 5 to 10 days of anticoagulation for the patient with cancer with newly diagnosed VTE who does not have severe renal impairment (defined as creatinine clearance <30 mL/min) ACCP 9th Ed 2012 In patients with DVT of the leg / PE and cancer, we suggest LMWH over VKA therapy (Grade 2B) .

Choice of treatment in patients with and without cancer is sensitive to the individual patient’s tolerance for daily injections, need for laboratory monitoring, and treatment costs.

ESMO 2011 The standard initial treatment of an acute episode of VTE in cancer and non- cancer patients consists:

  • LMWH s.c. at a dose adjusted to body weight: (e.g. dalteparin or

enoxaparin)

  • UFH - first administered as a bolus of 5000 IU, followed by continuous

infusion adjusted to achieve and maintain an activated partial thromboplastin time (aPTT) prolongation of 1.5–2.5 times the basal value.

Novel Agents in Cancer Patients

Guideline Recommendation International Consensus 2013 Premature to issue recommendations due to absence of data and clinical experience ASCO Update 2013 Use of novel oral anticoagulants for either prevention or treatment of VTE in patients with cancer is not recommended at this time. ACCP 9th Ed 2012 In patients with DVT and cancer who are not treated with LMWH, we suggest VKA over Dabigatran or Rivaroxaban ESMO 2011 Not specified

Case 1 - Answer

MM working group – Palumbo 2008 Regardless of other risk factors, combination of thalidomide plus multi-agent chemotherapy indicates for LMWH 40mg daily or full dose warfarin ACCP 9th Edition 2012 4.2.2. In outpatients with solid tumours who have additional risk factors for VTE (includes Thal/Len) and who are at low risk of bleeding, we suggest prophylactic dose LMWH or LDUH over no prophylaxis (Grade 2B) . ASCO Update 2013 2.3 Patients with multiple myeloma receiving thalidomide- or lenalidomide-based regimens with chemotherapy and/or dexamethasone should receive pharmacologic thromboprophylaxis with either aspirin or LMWH for lower risk patients and LMWH for higher-risk patients.

Case 3 - Answer

SISET 2012 (Italian Society Haemostasis and Thrombosis) Pharmacological prophylaxis is not routinely recommended in patients undergoing chemotherapy or radiotherapy or hormonal therapy (grade C) except in the following cases:

  • Patients with lung or gastrointestinal cancer should receive nadroparin (3,800 U anti-FXa daily) for no

more than 4 months (grade A)

  • Patients with multiple myeloma treated with thalidomide or lenalidomide plus high-dose

dexamethasone should receive LMWH or aspirin or warfarin (Grade C) ACCP 9th Edition 2012 4.2.1. In outpatients with cancer who have no additional risk factors for VTE, we suggest against routine prophylaxis with LMWH or LDUH (Grade 2B) and recommend against the prophylactic use of VKAs (Grade 1B) .

*Remarks: Additional risk factors for venous thrombosis in cancer outpatients include previous venous thrombosis, immobilization, hormonal therapy, angiogenesis inhibitors, thalidomide, and lenalidomide.

ASCO Update 2013 2.1 Routine pharmacologic thromboprophylaxis is not recommended in cancer outpatients. 2.2 Based on limited RCT data, clinicians may consider LMWH prophylaxis on a case-by-case basis in highly selected outpatients with solid tumors receiving chemotherapy. Consideration of such therapy should be accompanied by a discussion with the patient about the uncertainty concerning benefits and harms as well as dose and duration of prophylaxis in this setting.

  • Ability to monitor (anti-Xa)
  • Absence of drug interactions (Rivaroxaban and Pazopanib = CYP3A4)
