Health status, late effects and long-term survivorship of allogeneic bone marrow transplantation: a retrospective study.

BACKGROUND

Survival after allogeneic haemopoietic stem cell transplantation (allo-HSCT) has improved because of advancements in allo-HSCT. Allo-HSCT has been performed in Australia since the late 1970s. However, there are few published data about health problems of allo-HSCT survivors in Australia.

AIMS: Identify health issues in long-term survivors of allo-HSCT in an Australian centre to manage better and prevent long-term complications.

METHODS

The health records of all patients of allo-HSCT in a single centre from January 2000 to December 2007 and survived beyond 2 years were assessed.

RESULTS

Ninety-nine of the 200 allo-HSCT patients survived beyond 2 years, and the median time from allo-HSCT was 74 months. Twenty-eight per cent died at a median of 37 months after allo-HSCT because of relapsed malignancy (12%), stroke (1%), infection (3%), chronic graft versus host disease (9%), secondary malignancy (2%) and unknown cause (1%). Ninety-one per cent reported one or more chronic health conditions. Health issues were chronic graft versus host disease (70%); respiratory (66%), ophthalmic (40%), bone (33%), and renal (26%) problems; and malignancies (14% skin, 3% solid organ). Seventy-nine per cent resumed vocation at full or reduced capacity 2 years after allo-HSCT. Clinicians identified 40% with quality of life (QOL) issues, but survivors' self-reported QOL was comparable with the general Australian population.

CONCLUSION

This study shows that allo-HSCT patients are living with high burdens of chronic diseases that warrant lifelong surveillance and engagement with healthcare. Structured, multi-disciplinary care as recommended by published guidelines for allo-HSCT survivors may reduce long-term effects and improve their outcomes.
