Looking under the hood of "the Cadillac of cancers:" radioactive iodine-related craniofacial side effects among patients with thyroid cancer

Purpose Despite having a generally favorable prognosis, differentiated thyroid cancer is known to have a significant, long-term impact on the quality of life of survivors. We wished to investigate short- and long-term effects among thyroid cancer survivors following radioactive iodine therapy. Methods We conducted eight focus groups (N = 47) to understand patients' experiences of short- and long-term effects after radioactive iodine treatment and the impact these treatment-related side effects had on patients' quality of life. We elicited responses regarding experiences with side effects following radioactive iodine treatment, particularly salivary, lacrimal, and nasal symptoms. We transcribed audiotapes and conducted qualitative analyses to identify codes and themes. Results We identified eight broad themes from the qualitative analyses. Themes reflecting physical symptoms included dry mouth, salivary gland dysfunction, altered taste, eye symptoms such as tearing or dryness, and epistaxis. Psychosocial themes included lack of knowledge and preparation for treatment, regret of treatment, and distress that thyroid cancer is labeled as a "good cancer." Conclusions Thyroid cancer survivors reported a wide range of radioactive iodine treatment-related effects and psychosocial concerns that appear to reduce quality of life. The psychosocial concerns reported by participants underscore the significant unmet information and support needs prior to and following RAI treatment among individuals diagnosed with thyroid cancer. Implications for Cancer Survivors Future research is needed to help both patients and physicians understand the effect of radioactive iodine on quality of life, and to better assess the benefits versus the risks of radioactive iodine therapy.
