Purpose: To evaluate the efficacy of radiotherapy (RT) with total dose of 20 Gy (RT 20 Gy) in the treatment of Graves' ophthalmopathy. Methods: A systematic review and metaanalysis of randomized controlled trials was performed comparing RT 20 Gy with or without glucocorticoid to cli nical treatments for Graves' ophthalmopathy. The MEDLINE, EMBASE, Cochrane Library databases and recent relevant journals were searched. Relevant reports were reviewed by two reviewers. Response to radiotherapy was defined as clinical success according to each trial. We also evaluated the quality of life and whether RT to produce fewer side effects than other treatments. Results: A total of 8 randomized controlled trials (439 patients) were identified. In the subgroup analysis, the overall response to treatment rates was better for: RT 20 Gy plus glucocorticoid vs glucocorticoids alone, OR=17.5 (CI95% 1.85250, p=0.04), RT 20 Gy vs sham RT, OR= 3.15 (CI95%1.596.23, p=0.003) and RT 20Gy plus intravenous glucocorticoid vs RT 20Gy plus oral glucocorticoid, OR=4.15(CI95% 1.3412.87, p=0.01). There were no differences between RT 20 Gy versus other fractionations and RT 20 Gy versus glucocorticoid alone. RT 20 Gy with or without glucocorticoids showed an improvement in diplopia grade, visual acuity, optic neuropathy, lid width, proptosis and ocular motility. No difference was seen for costs, intraocular pressure and quality of life. Conclusion: Our data have shown that RT 20 Gy should be offered as a valid the rapeutic option to patients with moderate to severe ophthalmopathy. The effecti veness of orbital radiotherapy can be increased by the synergistic interaction with glucocorticoids. Moreover, RT 20 Gy is useful to improve a lot of ocular symptoms, excluding intraocular pressure, without any difference in quality of life and costs.
OSAS is prevalent in postmenopausal women, especially in late postmenopause. This study highlights the association between waist circumference, early postmenopause and late postmenopause, and severity of OSAS. Our findings suggest that postmenopause stages may potentially exacerbate the presence of sleep disturbance and that reducing waist circumference may be an important strategy for managing OSAS in women.
Objective: To determine the role of prophylactic cranial irradiation (PCI) in patients with small cell lung cancer (SCLC). Methods: We searched various databases, selecting randomized clinical trials published in journals or conference proceedings within the last 30 years and investigating the role of PCI in the mortality of patients with SCLC, submitted to PCI or not. Results: Sixteen randomized clinical trials, collectively involving 1,983 patients, were considered eligible for inclusion. Of those 1,983 patients, 1,021 were submitted to PCI and 962 were not. Overall mortality was 4.4% lower in the patients submitted to PCI than in those who were not Descritores: Carcinoma de pequenas células do pulmão; Radioterapia; Análise de sobrevida.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
