Primary Outcome Measures:
  • Hemoglobin level [ Time Frame: 8 postoperative weeks ] [ Designated as safety issue: No ]
    Hemoglobin level measured at 8 postoperative weeks

Secondary Outcome Measures:
  • Ferritin levels [ Time Frame: Preoperative (one day before surgery) and 1, 4 and 8 postoperative weeks ] [ Designated as safety issue: No ]
  • FACIT [ Time Frame: Preoperative (one day before surgery) and 1, 4 and 8 postoperative weeks ] [ Designated as safety issue: No ]
    The FACIT Fatigue Scale is a health related quality of life (HRQOL) questionnaire targeted to evaluate fatigue.

  • SF36 [ Time Frame: Preoperative (one day before surgery) and 1, 4 and 8 postoperative weeks ] [ Designated as safety issue: No ]
    Quality of Life Questionnaire

  • Transferrin saturation [ Time Frame: Preoperative (one day before surgery) and 1, 4 and 8 postoperative weeks ] [ Designated as safety issue: No ]
  • Hemoglobin levels [ Time Frame: preoperative (one day before surgery) and 1, 4 postoperative weeks ]
