Summary:A total of 75 patients underwent sibling allogeneic stem cell transplantation (SCT) for chronic myeloid leukaemia in first chronic phase from 1984 to 2000. Of these patients, 51 (68%) were alive at a median follow-up of 98 months (range 34-217 months). Nine (18%) patients relapsed and seven (14%) received donor lymphocyte transfusions. Quality of life (QoL) was assessed crosssectionally using the EORTC QLQ-C30, a Leukaemia-BMT-specific module and questionnaires on sexual functioning, fertility and late effects. A total of 46 (90%) replied. Scores for Role (P ¼ 0.018) and Cognitive (Po0.001) function were significantly lower when compared to an age-adjusted general population. Dyspnoea (P ¼ 0.022) and Financial Difficulties (Po0.001) were significantly more common in the SCT group. No difference was found for scores in the Physical, Emotional and Social domains or the overall Global Health Status/ QoL. Decreased sexual functioning was found in one-third of respondents. Although most BMT recipients reported a good QoL, a minority have difficulty with reintegration into professional roles and consequent monetary problems. Identified cognitive and sexual impairments highlight the need for long-term access to psychosocial support.

The most recent EBMT registry survey reported that the median survival of patients who underwent non-T-celldepleted transplantation for CML in first chronic phase (CP) from an HLA-matched sibling donor had not been reached at 10 years. 2 Health-related quality of life (QoL) has been defined as referring 'to the extent to which one's usual or expected physical, emotional and social well-being are affected by a medical condition or its treatment'. 3 Most of the previous studies are cross-sectional in design, apply one of several available instruments and pool all patients transplanted for different diagnoses at a single centre. [4][5][6][7][8][9][10][11][12] Although marked morbidity in the first few years is evident, there is a clear trend to improved QoL in long-term survivors of transplantation. 6,8 Nonetheless, aggregated studies confirm that a minority of individuals continue to suffer from the effects of chronic graft-versus-host disease (GvHD) and sexual dysfunction. Our observations confirm and extend those of Kiss et al 12 in a group of 24 patients receiving SCT for CML in first CP.The European Organisation for Research and Treatment of Cancer (EORTC) QoL questionnaire -QLQ-C30 13 -was used in this study. Both EORTC population reference data and CML-specific data have been generated using this instrument. [14][15][16] In addition to t...
