Functional capacity, pulmonary function, and quality of life in hematopoietic stem cell transplantation survivors.

OBJECTIVE

Hematopoietic stem cell transplantation (HSCT) is used as a treatment for several diseases. The objective was to evaluate the functional capacity, pulmonary function, and quality of life (QoL) in HSCT survivors.

METHODS

The patients were submitted to spirometry and six-minute walk test (6MWT) and evaluation of QoL (Functional Assessment of Cancer Therapy Bone Marrow Transplantation-FACT-BMT) and the level of physical activity (Human Activity Profile-HAP) in the post-HSCT outpatient ambulatory.

RESULTS

The sample was composed of 103 individuals with a mean age of 42.1 ± 12 and a median HSCT time of 5 (2-11) years. The average distance walked in the 6MWT was 524.7 ± 73.5 m; the FACT-BMT score, 82 ± 8.7 points; FEV, 76.8 ± 22.6%; and HAP, 71.9 ± 11.2 points. There was a significant difference between debilitated and physically active individuals for the variables: forced expiratory volume in the first second (FEV) in liters (p = 0.008) and % of predicted (p = 0.017), FEV/FVC (p = 0.032), distance on the 6MWT (p < 0.001), fatigue after the 6MWT (p < 0.001), and physical well-being (p = 0.005).

CONCLUSIONS

HSCT survivors have long-term changes in functional capacity, pulmonary function, and QoL. Subjects more active had better results in pulmonary function and functional capacity.
