RESUMO

BACKGROUND: The aim of this study was to evaluate the effectiveness of prophylactic corticosteroids to prevent pain flare (PF) in bone metastases treated with radiotherapy performing a meta-analysis of randomized clinical trials (RCT). MATERIALS AND METHODS: RCTs were identified on Medline, Embase, the Cochrane Library, and the proceedings of annual meetings through June 2020. We followed the PRISMA and MOOSE guidelines. A meta-analysis was performed to assess if corticosteroids reduce the PF, pain progression, and the mean of days with PF compared with the placebo. A p-value < 0.05 was considered significant. RESULTS: Three RCTs with a total of 713 patients treated were included. The corticosteroids reduced the occurrence of early PF 20.5% (51/248) versus 32% (80/250) placebo, OR = 0.55 (95% CI: 0.36-0.82, p = 0.002). The mean days of PF were reduced to 1.6 days (95% CI: 1.3-1.9, p = 0.0001). Prophylactic corticosteroids had more patients with no PF and no pain progression, OR = 1.63 (95% CI: 1.14-2.32, p = 0.007). No significant corticosteroids effect was observed for pain progression (p = ns) and late PF occurrence (p = ns). CONCLUSION: Prophylactic corticosteroids reduced the incidence of early PF, the days with PF, resulting in a superior rate of patients with no PF and no pain progression, but with no significant benefit for reducing pain progression or late PF occurrence.

RESUMO

PURPOSE: The effectiveness and safety of high dose brachytherapy as monotherapy (HDR-BRT-M) in prostate cancer is limited to retrospective studies. We performed a meta-analysis to summarize existing data and identify trends in biochemical recurrence-free survival (bRFS) and toxicity after HDR-BRT-M in patients with prostate cancer. METHODS AND MATERIALS: Retrospective, prospective, or randomized clinical trials were identified on electronical databases through June 2020. We followed the PRISMA and MOOSE guidelines. A meta-regression analysis was performed to assess if there is a relationship between moderator variables and bRFS. A p-value < 0.05 was considered significant. RESULTS: Fourteen studies with a total of 3534 patients treated were included. The cumulative size of the bRFS at 5 years was 0.92 (95% confidence interval (CI) 0.48-0.61). The five-year bRFS for low, intermediate, and high risk was 97.5% (95% CI 96-98%), 93.5% (95% CI 91-96%), and 91% (95% CI 88-93%), respectively. The total biological effective dose (BED) (p = 0.02), the BED per fraction (p = 0.001), androgen deprivation therapy usage (p = 0.04), and the number of fractions of HDR-BRT-M (p = 0.024) were significantly associated with bRFS rate. The rate of late Grade 2/3 or > genitourinary and gastrointestinal toxicity was 22.4% (95% CI 9-35,2%)/1.4% (95% CI 0.8-2.1%) and 2.7% (95% CI 0-6.8%) and 0.2% (95% CI 0.1%-0.4%), respectively. CONCLUSIONS: HDR-BRT-M is safe with excellent rates of bRFS for all risk groups. The total BED, the BED per fraction, and number of fractions were the key factors associated with the biochemical control. These data can be useful to choose the size and number of BRT fractionation.

RESUMO

PURPOSE: The purpose of this study was to compare the treatment outcomes of partial-breast irradiation (PBI) versus whole-breast radiotherapy (WBRT) in early breast cancer. METHODS AND MATERIALS: Eligible randomized clinical trials were identified on Medline, Embase, the Cochrane Library, and the proceedings of annual meetings through December 2019. A meta-analysis for local recurrence (LR), overall mortality (OM), and non-breast cancer mortality (NBCM) was conducted. When possible, the outcomes were calculated for 5, 7, and 10 years of followup. A subgroup analysis by PBI technique (brachytherapy [BT], external beam radiotherapy [EBRT], intraoperative radiotherapy [IORT], and mixed) was performed. A p value < 0.05 was considered significant. RESULTS: Eleven randomized clinical trials with a total of 14,436 patients (7186 PBI vs. 7250 WBRT) were included in the meta-analysis. The odds ratio (OR) for LR in 5 y was 1.46 (95% CI 1.15-2, p = 0.024) for PBI. In the subgroup analysis, no significant difference for LR was observed between PBI and WBRT using BT (p = 0.51), EBRT (p = 0.25), or mixed techniques (p = 0.89). The only subgroup with statistical difference was IORT 3.1 (95% CI 1.2-7.6, p = 0.014). No significant difference in LR was observed with 7 and 10 years among the groups. The OM had no difference at 5, 7, and 10 years of followup for any subgroup. A nonsignificant difference was observed comparing PBI with WBRT for NBCM OR = 1.24 (95% CI 0.98-1.57, p = 0.07). The rates of cardiac death, contralateral breast cancer, and development of second tumor were not significant. CONCLUSIONS: The LR with PBI is low and similar to WBRT in selected early breast cancer with a longer followup. The subgroup analysis detected a significant difference for LR associated with IORT and no significant difference for BT and EBRT. Our results confirm a nonsignificant difference for OM and NBCM between PBI and WBRT.

RESUMO

PURPOSE: Patients with visual impairment are constantly facing challenges to achieve an independent and productive life, which depends upon both a good visual discrimination and search capacities. Given that visual search is a critical skill for several daily tasks and could be used as an index of the overall visual function, we investigated the relationship between vision impairment and visual search performance. METHODS: A comprehensive search was undertaken using electronic PubMed, EMBASE, LILACS, and Cochrane databases from January 1980 to December 2016, applying the following terms: "visual search", "visual search performance", "visual impairment", "visual exploration", "visual field", "hemianopia", "search time", "vision lost", "visual loss", and "low vision". Two hundred seventy six studies from 12,059 electronic database files were selected, and 40 of them were included in this review. RESULTS: Studies included participants of all ages, both sexes, and the sample sizes ranged from 5 to 199 participants. Visual impairment was associated with worse visual search performance in several ophthalmologic conditions, which were either artificially induced, or related to specific eye and neurological diseases. CONCLUSIONS: This systematic review details all the described circumstances interfering with visual search tasks, highlights the need for developing technical standards, and outlines patterns for diagnosis and therapy using visual search capabilities.

RESUMO

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 meta-analysis of randomized controlled trials was performed comparing RT 20 Gy with or without glucocorticoid to clinical 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% 1.85-250, p=0.04), RT 20 Gy vs sham RT, OR= 3.15 (CI95%1.59-6.23, p=0.003) and RT 20Gy plus intravenous glucocorticoid vs RT 20Gy plus oral glucocorticoid, OR=4.15(CI95% 1.34-12.87, 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 therapeutic option to patients with moderate to severe ophthalmopathy. The effectiveness 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.


OBJETIVO: Avaliar a eficácia da radioterapia (RT) com dose total de 20 Gy (RT 20 Gy) no tratamento da oftalmopatia de Graves. MÉTODOS: Uma revisão sistemática e meta-análise de ensaios clínicos randomizados foram realizadas comparando RT 20 Gy, com ou sem glicocorticoides a tratamentos clinicos para a oftalmopatia de Graves. O MEDLINE, EMBASE, bases de dados da Biblioteca Cochrane e recentes de revistas relevantes foram pesquisados. Relatórios relevantes foram revisados por dois revisores. A resposta à radioterapia foi definida através do sucesso clinico de acordo a cada ensaio clínico. Nós também avaliamos a qualidade de vida e se a radioterapia produzia menos efeitos colaterais comparados a outras intervenções. RESULTADOS: Um total de 8 ensaios clínicos randomizados (439 pacientes) foram identificados. Na análise de subgrupo, a resposta global para as taxas de tratamento foi melhor para: RT 20 Gy além de glicocorticoides vs glicocorticoides sozinhos, OR=17,5 (IC95% 1,85-250, p=0,04), RT 20 Gy vs sham RT, OR=3,15 (IC95% 1,59-6,23, p=0,003) e RT 20 Gy além de glicocorticoides por via intravenosa RT 20 Gy além de glicocorticoides orais, OR=4,15 (IC95% 1,34-12,87, p=0,01). Não houve diferenças entre RT 20 Gy contra outros fracionamentos e 20 Gy RT contra glicocorticoides sozinhos. RT 20 Gy, com ou sem glicocorticoides mostraram uma melhoria no grau de diplopia, acuidade visual, neuropatia óptica, abertura palpebral, proptose e da motilidade ocular. Não foi observada diferença para os custos, a pressão intraocular e a qualidade de vida. CONCLUSÃO: Nossos dados mostraram que 20 Gy RT deve ser oferecida como uma opção terapêutica válida para pacientes com moderada a severa oftalmopatia de Graves. A eficácia da radioterapia orbital pode ser aumentada pela interação sinérgica com os glicocorticoides. Além disso, RT 20 Gy é útil para melhorar vários sintomas oculares, excluindo a pressão intraocular, sem qualquer diferença de qualidade de vida.

RESUMO

PURPOSE: To evaluate the effectiveness and safety of postoperative low single-dose of beta-irradiation (ß-RT) in pterygium comparing conjunctival autograft (CAG) surgery with CAG plus adjuvant ß-RT in a randomized clinical trial. METHODS: This trial was designed as a prospective, randomized, single-center study. Surgery was performed in all cases according to the CAG technique. One hundred and eight pterygia were postoperatively randomized to CAG + ß-RT or CAG alone. In the case of ß-RT, a (90) Sr eye applicator was used to deliver 10 Gy to the sclera surface at a dose rate of between 200 and 250 cGy/min. After treatment, both an ophthalmologist and a radiation oncologist performed the follow-up examinations. The accumulated data were analyzed using a group sequential test. RESULTS: Between February 2008 and September 2008, 116 eyes with primary pterygium were operated on according to the trial protocol. Adjuvant treatment was performed within 24 h postoperatively. Eight patients were lost to follow-up, resulting in 108 patients who could be analyzed. At a mean follow-up of 18 months (range, 8-33), in the 54 eyes randomized to receive CAG + ß-RT, 5 relapses occurred compared with 12 recurrences in the 54 eyes in CAG, for a crude control rate of 90.8 % vs. 78%; p = 0.032, respectively. The treatment complications as hyperemia, total dehiscence of the autograft and dellen were significantly more frequent in the CAG (p < 0.05). The arm of ß-RT resulted in better cosmetic results and improves of symptoms than CAG. CONCLUSIONS: A low single-dose of ß-RT of 10 Gy after CAG surgery was a simple, effective, and safe treatment that reduced the risk of primary pterygium recurrence, improved symptoms after surgery, resulting in a better cosmetic effect than only CAG.

RESUMO

PURPOSE: Postoperative adjuvant treatment using ß-radiotherapy (RT) is a proven technique for reducing the recurrence of pterygium. A randomized trial was conducted to determine whether a low fractionation dose of 2 Gy within 10 fractions would provide local control similar to that after a high fractionation dose of 5 Gy within 7 fractions for surgically resected pterygium. METHODS: A randomized trial was conducted in 200 patients (216 pterygia) between February 2006 and July 2007. Only patients with fresh pterygium resected using a bare sclera method and given RT within 3 days were included. Postoperative RT was delivered using a strontium-90 eye applicator. The pterygia were randomly treated using either 5 Gy within 7 fractions (Group 1) or 2 Gy within 10 fractions (Group 2). The local control rate was calculated from the date of surgery. RESULTS: Of the 216 pterygia included, 112 were allocated to Group 1 and 104 to Group 2. The 3-year local control rate for Groups 1 and 2 was 93.8% and 92.3%, respectively (p = .616). A statistically significant difference for cosmetic effect (p = .034), photophobia (p = .02), irritation (p = .001), and scleromalacia (p = .017) was noted in favor of Group 2. CONCLUSIONS: No better local control rate for postoperative pterygium was obtained using high-dose fractionation vs. low-dose fractionation. However, a low-dose fractionation schedule produced better cosmetic effects and resulted in fewer symptoms than high-dose fractionation. Moreover, pterygia can be safely treated in terms of local recurrence using RT schedules with a biologic effective dose of 24-52.5 Gy(10.).

RESUMO

PURPOSE: To study the efficacy of whole brain radiotherapy (WBRT) with radiosensitizer in comparison with WBRT alone for patients with brain metastases in terms of overall survival, disease progression, response to treatment and adverse effects of treatment. METHODS: A meta-analysis of randomized controlled trials (RCT) was performed in order to compare WBRT with radiosensitizer for brain metastases and WBRT alone. The MEDLINE, EMBASE, LILACS, and Cochrane Library databases, in addition to Trial registers, bibliographic databases, and recent issues of relevant journals were researched. Significant reports were reviewed by two reviewers independently. RESULTS: A total of 8 RCTs, yielding 2317 patients were analyzed. Pooled results from this 8 RCTs of WBRT with radiosensitizer have not shown a meaningful improvement on overall survival compared to WBRT alone OR = 1.03 (95% CI0.84-1.25, p = 0.77). Also, there was no difference in local brain tumor response OR = 0.8(95% CI 0.5 - 1.03) and brain tumor progression (OR = 1.11, 95% CI 0.9 - 1.3) when the two arms were compared. CONCLUSION: Our data show that WBRT with the following radiosentizers (ionidamine, metronidazole, misonodazole, motexafin gadolinium, BUdr, efaproxiral, thalidomide), have not improved significatively the overall survival, local control and tumor response compared to WBRT alone for brain metastases. However, 2 of them, motexafin- gadolinium and efaproxiral have been shown in recent publications (lung and breast) to have positive action in lung and breast carcinoma brain metastases in association with WBRT.

RESUMO

PURPOSE: To assess quality and cut-off point (VA <0.7) of the examinations performed by teachers to detect reduced visual acuity (VA) in schoolchildren participants of the project called "Eye in eye " in Marilia-SP, Brazil. METHODS: Visual acuity measurements were performed by trained teachers using Snellen's chart. The children with VA <0.7 in one of the eyes were referred to an ophthalmic examination. The ophthalmic examination was considered gold standard to assess quality and cut-off point of the examinations performed by teachers. VA test was performed in 604 schoolchildren of state public schools (1,208 eyes). Analyses were based on examined eyes. We calculated sensitivity (S), specificity (E), positive predictive value (PPV), negative predictive value (NPV) and likelihood rate (LR). We compared the means obtained by the teachers' examinations to means of the ophthalmologist's examinations. ROC curve was produced to evaluate whether VA lower than 0.7 is the best value for referral to an ophthalmic examination. RESULTS: VA means obtained by teachers and ophthalmologic examinations were 0.70 +/- 0.16 and 0.88 +/- 0.2 respectively. The difference between teachers' and ophthalmologists' examinations was 0.18 (p<0.0001). S, E, PPV, NPV and LR were: 82%, 40%, 27%, 89% and 1.37, respectively. False positive and negative rates were 59.5% and 18%. ROC curve evidenced that visual acuity of 0.7 was the best cut-off point to refer schoolchildren to an ophthalmic exam. CONCLUSIONS: We demonstrated the importance of the teachers' participation in improved schoolchildren ocular health. The examination performed by teachers obtained a satisfactory S with low E, NPV and high values of false positive results. The best cut-off point to refer schoolchildren to an ophthalmic examination was VA of 0.7.

RESUMO

OBJETIVOS: Avaliar a qualidade e o ponto de corte (AV <0,7) da acuidade visual verificada pelos professores, nos escolares da rede municipal de Marília participantes do programa "Olho no olho". MÉTODOS: Estudo transversal em 604 escolares (1.208 olhos), pertencentes às escolas municipais de Marília, SP, realizado através do exame feito pelos professores treinados para o programa comparando-o com o exame realizado pelos oftalmologistas, assumindo estes como o padrão-ouro para comparação. A análise foi feita por olhos examinados. Calculamos a sensibilidade (S), especificidade (E), valor preditivo positivo (VPP), valor preditivo negativo (VPN) e razão de verossimilhança (RV). Comparamos as médias das AV encontradas pelos professores com as dos oftalmologistas e uma curva ROC (Receiver Operating Characteristic Curve) foi gerada para avaliar se AV <0,7 foi o melhor valor para encaminhamento. RESULTADOS: A média da AV verificada pelos professores foi de 0,70 +/- 0,16 e a dos oftalmologistas foi de 0,88 +/- 0,2 com uma diferença entre as médias de 0,18 (p<0,0001). A S, E, VPP, VPN e RVP foram de: 82 por cento, 40 por cento, 27 por cento, 89 por cento e 1,37, respectivamente. As taxas de falso positivo e negativo foram de 59,5 por cento e 18 por cento, respectivamente. Na curva ROC AV <0,7 foi o melhor ponto para encaminhamento. CONCLUSÕES: Evidenciamos a importância da participação dos professores na melhoria da saúde ocular escolar. O teste realizado pelos professores teve satisfatória S, com baixa E, VPN e valores elevados de falsos positivos. Nossos dados confirmam que o melhor valor de corte para encaminhamento foi o valor de AV < 0,7.

RESUMO

PURPOSE: To evaluate the long-term safety, effectiveness, and prognostic factors of fractionated postoperative beta-irradiation. METHODS AND MATERIALS: Between 1993 and 2005, 623 patients with 737 pterygium lesions were treated with a strontium-90 eye applicator after surgical excision. The median follow-up period was 60 months (range, 6.7-139.5). Of the 737 lesions, 644 were primary and 93 were recurrences after surgical removal alone. Fractionated radiotherapy (RT) to a total dose of 35 Gy in five to seven fractions was used. RESULTS: A total of 73 local pterygium recurrences (9.9%) were noted. Of the recurrent cases, 80% were noted within 3 years after treatment. The 5- and 10-year probability of local control was 90% and 88%, respectively. The multivariate analysis for all cases demonstrated that gender, age, total radiation dose, recurrent pterygia, and interval between surgery and RT affected the overall local control rate. Late toxicities that might have been associated with strontium-90 RT included scleromalacia (scleral thinning) in nine eyes, adhesion of the eyelids in eight, cataracts in six, and scleral ulcer in five eyes.
