ABSTRACT
Abstract Whole-body bone scintigraphy (WB-BS) is used for detecting and monitoring metastatic spread of prostate cancer (PCa) and to investigate bone pain episodes. To investigate the impact of a positive WB-BS on pain-relieving medicine prescription in PCa patients, a single-center, retrospective cohort study with PCa patients classified as positive for bone metastases (BM) by WB-BS was conducted. Demographic, clinical, and ambulatory pain-relieving medicine prescription data were evaluated. Pain-relieving medicines were categorized according to the WHO 'Analgesic Ladder'. Regimens adopted before and after WB-BS were compared. Differences were considered significant at p<0.05. A total of 180 PCa patients were diagnosed with BM, 64.4% of whom were ≥65 years of age. Thirty-three patients were prescribed analgesics only after WB-BS, mostly including NSAIDs and weak opioids. Pain-relieving prescription changed after WB-BS in patients with prescriptions before and after WB-BS, with a reduction in NSAIDs and adjuvants and an increase in weak and strong opioids. In addition, 40% of patients with WHO analgesic step 1 drugs and 21.7% of patients with WHO step 2 drugs before WB-BS changed to other WHO steps after WB-BS. Pain-relieving prescriptions changed after a positive WB-BS, providing evidence that it could contribute to clinical management of painful metastatic PCa patients.

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.
