Assessment of quality of life in thyroid cancer patients using the EORTC thyroid-specific questionnaire: a prospective cross-sectional study.

BACKGROUND: Many studies on the quality of life (QoL) among the thyroid cancer survivors have shown conflicting results. This may be since many of these studies have not used thyroid cancer-specific questionnaires.

PATIENTS AND METHODS: In our study we have translated the EORTC THY-34, validated and served it in a cross-sectional study to the assess the QoL among thyroid cancer patients free of disease during their routine follow-up. Patients were categorized based on the duration from treatment completion, ATA risk stratification, treatment received, number of RAI sessions and thyroid function status during analysis.

RESULTS: Overall, 220 thyroid cancer survivors were included in this study. In general, in the EORTC QLQ-C30, the global QoL of thyroid cancer patients were good with a mean score of 72.99. The highest score was that for social functioning (89.55). In the EORTC-THY34 all the patients in the cohort had relatively lower scores (on symptom scales). Overall, there was no difference in the QLQ-C30 and THY-34 QoL with respect to any of the categorization mentioned above. However, our thyroid cancer patients QoL scores were better and/or comparable to those in published literature and they were also better or comparable to the QoL of the general population those were available in literature.

CONCLUSIONS: There was no difference in the QoL scores based on various categories. To better understand the quality of life of these patients a prospective longitudinal study with baseline values and values at regular intervals might give us a better insight.
