Brief Summary:
This pilot clinical trial compares the safety of two different platelet transfusion "thresholds" among patients with blood cancer or treatment-induced thrombocytopenia whose condition requires anticoagulant medication (blood thinners) for blood clots. Giving relatively fewer platelet transfusions may reduce the side effects of frequent platelet transfusions without leading to undue bleeding.

Detailed Description:

PRIMARY OBJECTIVES:

I. To determine feasibility of a randomized controlled trial comparing two different platelet transfusion thresholds (50 x 10^9/L versus [vs] 30 x 10^9/L) in patients with treatment or malignancy-induced thrombocytopenia requiring therapeutic anticoagulation.

SECONDARY OBJECTIVES:

I. Progressive or new venous thromboembolic (VTE).

II. Progressive or new arterial thromboembolism (ATE).

III. Hemorrhagic events (World Health Organization [WHO] grade 2 or greater).

IV. A composite of I, II and III.

V. Major bleeds (WHO grade 3 or 4).

VI. Number of platelet transfusions per patient during the study period.

VII. Platelet transfusion related complications (including transfusion reactions, alloimmunization and volume overload).

VIII. Degree to which platelet target thresholds are achieved.

OUTLINE: Patients are randomized into 1 of 2 groups.

GROUP I (Lower dose): Patients undergo platelet transfusion on all days when the morning platelet count is below the threshold 30 x 10^9/L for up to 30 days or until the platelet count spontaneously recovers to > 50 x 10^9 for 3 consecutive days in the absence of transfusions.

GROUP II (Higher dose): Patients undergo platelet transfusion on all days when the morning platelet count is below the threshold 50 x 10^9/L for up to 30 days or until the platelet count spontaneously recovers to > 50 x 10^9 for 3 consecutive days in the absence of transfusions.

After completion of study, patients are followed up at 30 days.

Primary Outcome Measures :
  1. Number of Eligible Patients Approached for the Study [ Time Frame: Up to 1 year ]
  2. Number of Patients Approached for But Refusing Consent [ Time Frame: Up to 1 year ]
    Reasons for ineligibility will be reported qualitatively in order to inform future studies.

  3. Number of Patients Consenting to Enrollment [ Time Frame: Up to 1 year ]
  4. Number of Patients Eligible [ Time Frame: Up to 1 year ]
  5. Number of Patients Screened and Deemed Ineligible [ Time Frame: Up to 1 year ]
    Reasons for ineligibility will be reported qualitatively in order to inform future studies.

  6. Number of Patients Successfully Following Protocol [ Time Frame: Up to 1 year ]
    Will evaluate the number of patients successfully following protocol, defined as receiving transfusions 'on protocol' at the end of the study period.


Secondary Outcome Measures :
  1. Incidence of Hemorrhagic Events (World Health Organization Grade 2 or Greater) [ Time Frame: Up to 1 year ]
    Will evaluate the incidence of hemorrhagic events (World Health Organization grade 2 or greater).

  2. Major Bleeds (World Health Organization Grade 3 or 4) [ Time Frame: Up to 1 year ]
    Will evaluate the major bleeds (World Health Organization grade 3 or 4).

  3. Number of Platelet Transfusions Per Patient During the Study Period [ Time Frame: Up to 1 year ]
  4. Percent of Days on Which Subjects Are Transfused (or Transfusion Are Not Given) [ Time Frame: Up to 1 year ]
    The frequency with which transfusions are given despite a platelet count above the determined threshold will be documented, as will the frequency with which transfusions are not administered within 24 hours after a platelet count below the determined threshold.

  5. Platelet Transfusion Related Complications [ Time Frame: Up to 1 year ]
    Total number of transfusion reactions, patients experiencing alloimmunization and volume overload will be reported.

  6. Progressive or New Arterial Thromboembolism [ Time Frame: Up to 1 year ]
    Will evaluate the progression or new arterial thromboembolism by either documented acute electrocardiographic changes compatible with myocardial injury and/or serum biochemical changes diagnostic of myocardial infarction, or documented imaging (computed tomography or magnetic resonance imaging) changes compatible with infarct due to embolism in the presence of a new neurological deficit, or imaging demonstrated intraluminal filling defects in an arterial distribution accompanied by symptoms of acute ischemia (acute onset pain, pallor, loss of pulses or other end-organ damage).

  7. Progressive or New Venous Thromboembolic [ Time Frame: Up to 1 year ]
    Will evaluate the progressive or new venous thromboembolic. Will require imaging confirmation, defined as intraluminal filling defect(s) on contrast-enhanced computed tomography or incompressible venous segment(s) on ultrasonography.
