Radioiodine therapy can be used in differentiated thyroid carcinoma and requires extensive evaluation to ensure effectiveness and safety. Therefore, it is necessary to evaluate all health problems and medications used in the pre-radioiodine therapy period and comprehensive medication managementservices can serve as a screening tool in this context. The present study aims to describe critical clinical situations identified during the initial assessments of a comprehensive medication management service offered to differentiated thyroid carcinoma patients pre-radioiodine therapy, and the pharmaceutical interventions performed to solve them. A descriptive study with regard to the initial ten months of a comprehensive medication management service was carried out in a large oncology hospital (Rio de Janeiro, Brazil). Descriptive analysis was used to describe the critical clinical situations identified, as well as the correspondent drug therapy problems and the type, acceptability, and outcomes of the pharmaceutical interventions performed to solve them. Thirty patients with an average of 45.8 years and 5.1 medications were evaluated. Five critical clinical situations were identified; corresponding to drug therapy problems two(needs additional drug therapy – n = 4) and drug therapy problems four (dosage too low – n = 1). All pharmaceutical interventions were accepted. The comprehensive medication management service provision pre-radioiodine therapy is feasible and represents an important screening strategy.

Purpose: The purpose of this study was to access changes in health-related quality of life (HRQoL) caused by radioiodine therapy (RAI) in thyroid cancer patients.Methods: Prospective cohort study at Brazilian National Cancer Institute with patients enrolled between March 2015 and June 2017. RAI was performed by administration of 1.11 to 9.25 GBq of Na131I. EORTC QLQ-C30 v3 and EORTC QLQ-H&N35 questionnaires were applied to determine HRQoL at baseline, 1 week and 3 months after RAI. HRQoL during follow-up was evaluated by calculation of score absolute changes in each domain. Descriptive analysis was performed by measures of central tendency and dispersion. Changes in HRQoL were evaluated by paired t-test. The association between social demographic and clinical data and HRQoL was assessed by univariate linear regression for significantly changed domains, and p < 0.05 was considered significant.Results: An improvement on global HRQoL and social Function post-therapy (p = 0.002 and p < 0.001) and on role (p = 0.038), emotional (p < 0.001), and cognitive function (p = 0.016) during RAI were observed. Nausea and vomiting (p < 0,001), pain (p < 0.001), sensitivity problems (p < 0.001), problems with social contact (p < 0.001), dry mouth (p = 0.007), and sticky saliva (p = 0.001) increased during RAI. Females were more sensible to changes in nausea and vomiting, and patients < 55 years experienced higher changes in sense during RAI.Conclusions: Although RAI might affect HRQoL negatively, patients experienced an improvement on global HRQoL and symptoms reduction post-therapy.
