NCT02604667

Brief Summary

The purpose of this study is to better understand the causes of stroke in people with cancer. Active cancer increases the risk of stroke. The investigators do not know exactly why this occurs but one possible reason is that people with cancer may have thicker blood than people without cancer. Thick blood can sometimes cause blood clots to form in the heart, which can then travel to the brain and cause stroke. This study is being done to help figure out why this and other causes of stroke occur in people with cancer. The investigators expect that information from this study will help doctors to more effectively prevent and treat stroke in individuals with cancer.

Outcome Measures

Primary Outcomes (1)

  • Hematological biomarker levels

    Hematological testing will consist of a single peripheral blood draw at 96 hours (+/-24 hours). Several factors will be evaluated, including markers of coagulation (thrombin-antithrombin complex, D-dimer), platelet function (P-selectin), and endothelial integrity (sICAM-1, sVCAM-1, thrombomodulin).

    At enrollment

Secondary Outcomes (1)

  • Peripheral leukocyte RNA gene expression profiles

    At enrollment

Other Outcomes (1)

  • Transcranial Doppler microemboli rates

    At enrollment

Study Arms (3)

Group 1: Cancer and Stroke

Patients with active solid tumor cancer and acute ischemic stroke. Will undergo blood tests and transcranial Doppler microemboli detection study.

Other: Blood testsOther: Transcranial Doppler Microemboli Detection Study

Group 2: Stroke and No Cancer

Patients with acute ischemic stroke and no cancer. Will undergo blood tests and transcranial Doppler microemboli detection study.

Other: Blood testsOther: Transcranial Doppler Microemboli Detection Study

Group 3: Cancer and No Stroke

Patients with active solid tumor cancer and no stroke. Will undergo blood tests and transcranial Doppler microemboli detection study.

Other: Blood testsOther: Transcranial Doppler Microemboli Detection Study

Interventions

Study participants will undergo a single, peripheral blood draw. Blood specimens will be used to perform hematological biomarker testing and leukocyte RNA gene expression analysis. Hematological biomarker testing will be performed to better elucidate the mechanisms of ischemic stroke in cancer patients and will include markers of coagulation, platelet function, and endothelial integrity. This analysis will occur at MSKCC. Leukocyte RNA gene expression analysis will be performed to evaluate whether patients with cancer and stroke more often have cardioembolic mechanisms than patients with stroke and no cancer. This analysis will occur at the University of California, Davis where investigators have previously shown that differential RNA expression patterns can predict stroke subtypes.

Group 1: Cancer and StrokeGroup 2: Stroke and No CancerGroup 3: Cancer and No Stroke

Study participants will undergo a single Transcranial Doppler Microemboli Detection Study at NYPH/WCMC or MSKCC within two weeks of enrollment. Both middle cerebral arteries will be insonated for 30 minutes by a trained technician or stroke neurologist certified in neurosonology using a fixed headset to assess for the rate and laterality of microemboli.

Study Population

We plan to enroll three groups of 50 patients each. Group 1 will consist of patients with acute ischemic stroke and active solid tumor cancer, Group 2 will include patients with acute ischemic stroke and no cancer, and Group 3 will include patients with active solid tumor cancer and no stroke.

You may qualify if:

  • years of age or older
  • Active solid tumor cancer (for Groups 1 and 3 only)
  • MRI confirmed acute ischemic stroke (for Groups 1 and 2 only)
  • Available for blood draw at 96 hours (+/- 24 hours) from last known well time (for Groups 1 and 2 only) or within 2 weeks of enrollment (for Group 3)
  • Available for TCD within 2 weeks of enrollment

You may not qualify if:

  • Primary brain tumor or hematological cancer
  • Treatment with intravenous or intraarterial thrombolysis or mechanical embolectomy
  • Platelets \< 50,000/mm3
  • Hemodialysis within 14 days
  • Active pregnancy
  • Infection within 14 days per Infectious Diseases Society of America (IDSA) criteria
