title: Short course pre-operative ferrous sulphate supplementation--is it worthwhile in patients with colorectal cancer?
abstract: BACKGROUND
  Pre-operative anaemia is well recognised in patients presenting with colorectal cancer (CRC). While the benefits of long-term FeSO4 supplementation on Fe deficiency anaemia are well established, it is not known if short-course supplementation (2-3 weeks) impacts significantly on pre-operative haemoglobin (Hb) levels. This study examines the impact of short-term, oral FeSO4 supplementation on patients undergoing surgery for CRC.
  
  
  METHODS
  All patients with CRC presenting to a single surgeon were included. At diagnosis, baseline Hb and blood film were checked on all patients who then received 200 mg tds of FeSO4. Haemoglobin was rechecked pre-operatively and daily postoperatively. Patients requiring pre-operative blood transfusions were excluded from analysis.
  
  
  RESULTS
  Between 1 January 2004 and 31 December 2006, 117 patients were identified, 14 of whom were excluded. Patients received a median of 39 days' treatment with FeSO4. Fifty-eight (56.3%) patients were anaemic at presentation gaining a mean of 1.73 g/dl (P<0.001) from short-course FeSO4 supplementation. Right-sided tumours (lower mean Hb at presentation; P=0.008) responded more to FeSO4 when compared to left-sided tumours (P<0.017). Increase in Hb was unrelated to pathological stage. The transfusion rate for all curative resections was 0.69 units/patient. For the historical cohort (patients undergoing curative resection between 1 January 2001 and 31 December 2003), the mean transfusion rate fell from 1.69 units/patient.
  
  
  CONCLUSIONS
  Routine short-course supplementation with iron offers improved pre-operative Hb prior to surgery in CRC, especially in right-sided lesions and those with presenting anaemia.
