: To evaluate if a supervised exercise training program improves the quality of life (QoL) of differentiated thyroid carcinoma (DTC) patients on TSH-suppressive therapy with levothyroxine (L-T4).
Subjects and methods
: Initially, a cross-sectional study was performed to compare the QoL and the health-related quality of life (HRQoL) between subclinical hyperthyroidism (SCH) patients (n = 33) and euthyroid subjects (EU; n = 49). In the prospective phase of the study, SCH patients were randomized in a non-blinded fashion to either participate (SCH-Tr = trained patients; n = 16) or not (SCH-Sed = untrained patients; n = 17) in a supervised exercise training program. The exercise program consisted of 60 minutes of aerobic and stretching exercises, twice a week, during twelve weeks. The QoL was assessed by the application of the WHOQOL-Bref, and the SF-36 was used to assess the HRQoL.
: SCH patients had statistically lower scores than EU on the “physical” domain of WHOQOL-Bref, besides “physical function”, “role-physical”, “bodily pain”, “general health”, “vitality”, “role-emotional”, and “mental-health” domains of SF-36. After three months, SCH-Tr patients showed improvement in the “physical” and “psychological” domains of WHOQOL-Bref (p < 0.05), and in the “physical function”, “role-physical”, “bodily pain”, “vitality” and “mental health” domains of SF-36.
: Patients on TSH-suppressive therapy with L-T4 for DTC had impaired QoL and HRQoL compared to EU, but it was improved after 3-months of an exercise training program. Exercise seems to play an important role in the follow-up of DTC patients, since it seems to minimize the adverse effects of the treatment on QoL and HRQoL.
