Quality of Life Survey Following Radioiodine Ablation in Patients with Differentiated Thyroid Cancer

Abstract

Thyroidectomy, due to malignancy, is usually followed by radioiodine ablation in order to treat residual or metastatic disease and ablate remnant thyroid tissue. The aim of this study was to investigate changes in patients’ health-related quality of life (HRQoL) before and after radioiodine ablation (RAI) and identify patients’ characteristics related. We conducted a cross-sectional study of 85 patients aged 20–82\xa0years old who had recently underwent near total thyroidectomy due to papillary-follicular thyroid cancer and were hospitalized in the Iodine Unit of a major hospital to receive RAI. HRQoL was estimated by 36-Item Short-Form Health Survey (SF-36) at three time points as follows: on the first day of their hospitalization, 3\xa0months after treatment, and 1\xa0year after treatment. Consistent with the previous literature, the results of this study revealed that HRQoL in DTC patients is independent with the majority of the variables examined. All SF-36 scales were significantly improved both times measured post Iodine-131 ( 131 I) administration in comparison with scores prior to RAI ( p \u2009<\u20090.05). One year after treatment, all SF-36 scales scores except from bodily pain and physical role were significantly lower than 3\xa0months post RAI scores ( p \u2009<\u20090.05). The results from this analysis suggest that thyroid cancer and its treatment procedures affect HRQoL across a variety of domains, despite the very good prognosis. HRQoL amelioration post RAI is mainly due to the removal of symptoms of hypothyroidism and familiarization with the treatment process.
