Brief Summary
Myelodysplastic syndromes (MDS) are bone marrow malignancies characterized by poor bone marrow function that may progress to acute myeloid leukemia. Many patients become red blood cell transfusion-dependent. Transfusion dependence is associated with inferior quality of life (QOL). However, the relationship between the degree of anemia and QOL is less clear. A commonly used transfusion strategy is to target the hemoglobin (Hb) in the range of 80-90 g/L (normal hemoglobin \> 120-130g/L). The question is: would a higher hemoglobin target lead to improvement in QOL despite the negative impact transfusion dependence may have on QOL (due to associated time commitments, expense, transfusion reactions etc). Several groups have prospectively shown that targeting hemoglobin levels of greater than 120 g/L (with hematopoietic growth factors (HGFs) and/or blood transfusions) or incremental increases of 15-20 g/L (with HGFs alone) were associated with improved QOL. The investigators MDS program has been conducting prospective assessments of QOL since 2007 in all registered and consented patients using a variety of validated questionnaires. Preliminary analysis (in 236 patients) revealed that, compared with an age-matched healthy general population, MDS patients have inferior QOL. Transfusion dependence and anemia were independently predictive of poor functioning, fatigue and decreased health utility. Furthermore, a hemoglobin level of ≥100 g/L seemed to be the key threshold for improvement in function and symptom scores. The investigators hypothesize that the target hemoglobins in transfusion dependent MDS patients are too low and this may account for their inferior quality of life. Our goal is to compare the effect on QOL of a restrictive strategy (which is the current standard of care), with a liberal transfusion strategy in a large randomized controlled trial of transfusion dependent MDS outpatients. Before embarking on such an endeavor, the investigators must first prove feasibility in a smaller pilot randomized controlled trial.

Outcome Measures
Primary Outcomes (1)
Percentage compliance of q2weekly hemoglobins
The percentage compliance of q2weekly hemoglobins being within or above the target range of the RBC transfusion threshold assigned (after the 4 week run-in at study start as defined above). We will consider this study feasible and worthy of future development into a larger randomized trial (powered for QOL difference) if compliance is ≥70%. A compliance rate of 50-70%, would not exclude going forward with such an RCT but only after careful discussion and statistical planning

Liberal transfusion strategy
EXPERIMENTALIntervention: Red Blood Cell transfusions. Transfuse pRBC at a higher threshold- maintain Hb level between 110 and 120 g/L: to achieve this, 2 units of pRBCs are transfused when Hb level is \< 105 g/L and 1 unit of RBCs when Hb level is 105-110 g/L. Transfusions administered more frequently.
Restrictive transfusion strategy
ACTIVE COMPARATORIntervention: Red Blood Cell transfusions. Transfuse pRBC at standard of care thresholds- maintain Hb level between 85 and 100 g/L: to achieve this, 2 units of packed red blood cells (pRBCs) will be transfused when the Hb level is \< 80 g/L and 1 unit of pRBCs when Hb level is 80-85 g/L: standard administration

Eligibility Criteria
You may qualify if:
- All patients with MDS ≥18 years of age
- Transfusion dependent: at least 1 transfusion per month in the last 8 weeks
- Hb \<100g/L pre transfusion
- Life expectancy \> 6 months
You may not qualify if:
- Unstable cardiac disease (Canadian Cardiovascular Society (CCS) III/IV angina or New York Heart Association (NYHA) III/IV congestive heart failure) requiring the transfusion target range to remain \>85-100 g/L at all times
- ECOG ≥3
- Patients with red cell antibodies against high frequency antigens or multiple antibodies (would potentially delay finding blood)
- Patients on ESA's or disease modifying agents (like azacitidine) for their MDS
