Abstract
PURPOSE The efficacy and safety of stereotactic body radiation (SBRT) for patients with non-spine bone metastases (NSBM) remains in question. A systematic review and meta-analysis was performed to evaluate SBRT treatment outcomes in NSBM. METHODS AND MATERIALS Eligible studies were retrieved from Medline, Embase, Scielo, the Cochrane Library, and annual meeting proceedings until July 6, 2023. We adhered to the PRISMA and MOOSE guideline recommendations. Quantitative synthesis was performed using a random effects model. RESULTS Seven retrospective studies, with a total of 807 patients (1048 lesions) treated with stereotactic body radiation were included, with median follow-up ranging from 7.6-26.5 months. The most common stereotactic body radiation sites were pelvis (39.2%), ribs (25.8%), femur (16.7%), and humerus/shoulder region (8.7%). At 1-year, the LF and FR were 7% (95%CI 5.5-8.5%; I2=0, n= 75/1048), and 5.3% (95%CI 3-7.5%;I2=0, n= 65/1010). The 2-year cumulative LF incidence was 12.1% (95% CI: 10-15.5%). The OS and PFS at 1-year were 82% (95%CI 75-88%;I2=82%, n= 746/867), and 33.5%(95%CI 26-41%;I2=0%, n= 51/152), with a median of 20.2 months (95%CI: 10.9-49.1 months) and 8.3 months (95% CI: 6.3-10.3%) for OS and PFS, respectively. Meta-regression analysis revealed a significant relationship between planning target volume and fracture rate (p<0.05). Ribs 2.5% followed by the femur 1.9% (95%CI:0-6.1%) were the most common fracture sites. The occurrence of pain flare, fatigue and dermatitis were 7 %, 5.4 %, and 0.65 %, respectively. CONCLUSIONS Stereotactic body radiation proves both safety and efficacy for non-spine bone metastases and serious complications (grade 3) are infrequent. Careful consideration of target volume is crucial due to its link with a higher fracture risk.

Abstract
BACKGROUND Compare outcomes after surgery (S) or radiotherapy (RT) for T1a-T1b glottic squamous cell carcinoma (T1GSCC) in a population-based cohort study. METHODS Patients diagnosed with T1GSCC from 1999 to 2020 were identified from a public database. Clinical, demographic, and social data were extracted. Treatment and patient groups and subgroups were compared with log-rank test, Cox proportional test, and propensity-score matched (PSM). RESULTS Eight hundred and eighty-eight patients with T1GSCC were included in the study, with a median follow-up of 61 months. The 5- and 10-year overall survival (OS) S versus RT were 76% versus 71% and 60% versus 52% (p = 0.02), respectively. In the subgroup analysis, S was associated with better OS for T1b, male, and public service patients (p < 0.05). In the PSM cohort of S versus RT with 110 patients each, there was no significant difference in the OS, CSS, and LC. CONCLUSIONS T1GSCC has favorable outcomes with S or RT.

Abstract
AIMS Reports of stereotactic arrhythmia radioablation (STAR) in patients with refractory ventricular tachycardia after catheter ablation are limited to small series. Here, we carried out a systematic review and meta-analysis of studies to better determine the efficacy and toxicity of STAR for ventricular tachycardia. MATERIALS AND METHODS Following the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) and the Meta-analyses Of Observational Studies in Epidemiology (MOOSE) guidelines, eligible studies were identified on Medline, Embase, Cochrane Library and the proceedings of annual meetings to 10 February 2023. Efficacy was defined as a ventricular tachycardia burden reduction >70% at 6 months; safety was defined as <10% of any grade ≥3 toxicity. RESULTS Seven observational studies with a total of 61 patients treated were included. At 6 months, the ventricular tachycardia burden reduction was 92% (95% confidence interval 85-100%) and use of fewer than two anti-arrhythmic drugs was seen in 85% (95% confidence interval 50-100). Six months after STAR, an 86% reduction (95% confidence interval 80-93) in the number of implantable cardioverter-defibrillator shocks was observed. The rates for improved, unchanged and decreased cardiac ejection fraction were 10%, 84% and 6%, respectively. Overall survival at 6 and 12 months was 89% (95% confidence interval 81-97) and 82% (95% confidence interval 65-98). The cardiac-specific survival at 6 months was 87%. Late grade 3 toxicity occurred in 2% (95% confidence interval 0-5%) with no grade 4-5 toxicity. CONCLUSION STAR demonstrated both satisfactory efficacy and safety for the management of refractory ventricular tachycardia and was also associated with a significant decline in anti-arrhythmic drugs consumption. These findings support the continued development of STAR as a treatment option.

Abstract
Background The safety and effectiveness of moderately hypofractionated post-operative radiation therapy for breast cancer were demonstrated by several trials. This study aimed to evaluate the current patterns of practice and prescription preference about moderately hypofractionated post-operative radiation therapy to assess possible aspects that affect the decision-making process regarding the use of fractionation in breast cancer patients in Latin America and the Caribbean (LAC). We also aimed to identify factors that can restrain the utilization of moderately hypofractionated post-operative radiation therapy for breast cancer. Materials an methods Radiation oncologists from LAC were invited to contribute to this study. A 38-question survey was used to evaluate their opinions. Results A total of 173 radiation oncologists from 13 countries answered the questionnaire. The majority of respondents (84.9%) preferred moderately hypofractionated post-operative radiation therapy as their first choice in cases of whole breast irradiation. Whole breast plus regional nodal irradiation, post-mastectomy (chest wall and regional nodal irradiation) without reconstruction, and post-mastectomy (chest wall and regional node irradiation) with reconstruction hypofractionated post-operative radiation therapy was preferred by 72.2% 71.1%, and 53.7% of respondents, respectively. Breast cancer stage, and flap-based breast reconstruction were the factors associated with absolute contraindications for the use of hypofractionated schedules. Conclusion Even though moderately hypofractionated post-operative radiation therapy for breast cancer is considered a new standard to the vast majority of the patients, its unrestricted application in clinical practice across LAC still faces reluctance.

Abstract
Background Stereotactic body radiotherapy (SBRT) has proven to provide high rates of tumor control for patients with early-stage non-small cell lung cancer (NSCLC). We are reporting a multicenter experience of long-term clinical outcomes and adverse effect profiles of patients with medically inoperable early-stage NSCLC treated with SBRT. Methods A total of 145 early-stage NSCLC patients underwent SBRT at the Cancer Hospital of the University of Chinese Academy of Sciences (Zhejiang Cancer Hospital), Shandong Cancer Hospital and Institute, and Shanghai Pulmonary Hospital between October 2012 and March 2019. Four-dimensional computed tomography (4D-CT) simulation was used for all patients. All received a biologically effective dose (BED; α/β=10) of 96-120 Gy with the prescribed isodose line covering >95% of the planning target volume (PTV). Survival was analyzed by the Kaplan-Meier method. Survival was estimated using the Kaplan-Meier method. Results The median tumor diameter was 2.2 (range, 0.5-5.2) cm. The median follow-up was of 65.6 months. Thirty-five patients (24.1%) developed disease recurrence. The rates of local, regional, and distant disease recurrence were, respectively, 5.1%, 7.4%, and 13.2% at 3 years; and 9.6%, 9.8%, and 15.8% at 5 years. Progression-free survival (PFS) rates at 3 and 5 years were 69.2% and 60.5% respectively; the overall survival (OS) rates were 78.1% and 70.1%, respectively. Five patients (3.4%) experienced grade 3 treatment-related adverse events (AEs). No patient experienced grade 4 or 5 toxicity. Conclusions From our retrospective analysis with long-term follow-up in Chinese population, SBRT achieved high rate of local control (LC) and low toxicity in patients with early-stage NSCLC. This study offered robust long-term outcome data of SBRT in the Chinese population, which was very rarely reported in China before.

Abstract
Background The Radiotherapy Expansion Plan for Brazil's Unified Health System (PER-SUS) was an innovative program designed by the Ministry of Health in 2012 to provide improvements to the challenging problem of access to radiotherapy in the country. This study sought to analyze the execution and implementation of installations proposed by PER-SUS, and their capacity to address the problems of radiotherapy access in Brazil. Methods From the first release (February 2015) until October 2021, all PER-SUS monthly progress reports were retrospectively analyzed. The beneficiary institutions, project location, project status, project type, dates of the progress on the stages, and reasons for cancellations or possible justifications for changing the status were collected. Brazilian geographic data, health care demands, and cancer incidences were correlated. Finally, we performed an Ishikawa diagram and 5W3H methodology, aiming to better understand the findings and to yield possible ways to improve the access to radiotherapy. Findings After ten years, the PER-SUS project delivered nearly 50% of the planned implementation of radiotherapy equipment. There was a 17% growth in the national number of linear accelerators (LINACS) with PER-SUS, against a 32% increase in cancer incidence in Brazil in the same period. The following points were identified: a high rate of beneficiary exclusions reflecting inappropriate selection or inadequate planning; delays in execution related to bureaucratic obstacles and underestimation of the requirements (logistics/people); early closing of the equipment factory as a result of lack of project prioritization by the Government. Interpretation Only about 50% of PER-SUS are being carried out. However, delays and exclusions of beneficiaries were observed. The dimension of the need for radiotherapy care in Brazil is greater than considered, and might not be fully attended by PER-SUS. Geographic, epidemiological, logistical, and economic variables could be reevaluated to allow better strategic planning and improvement proposals. PER-SUS could be optimized for the next decade, by involving all stakeholders' participation, alignment, and engagement. In the future, the States and regions with a higher LINAC shortage should be prioritized to improve RT access across the country. Considering the data and the initial project deadline, PER-SUS did not achieve the pre-established goals specified by the Brazilian Government. Funding This research did not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sectors.

Abstract
Objective: To evaluate the efficacy of stereotactic body radiotherapy (SBRT) versus surgery for early-stage non-small cell lung cancer (NSCLC) by means of a meta-analysis of comparative studies. Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and Meta-analysis of Observational Studies in Epidemiology guidelines, searches were performed on PubMed, MEDLINE, Embase, and Cochrane Library for eligible studies. The meta-analysis compared the hazard ratios (HR) for overall survival (OS), cancer-specific survival (CSS), and local control (LC). Subgroup and meta-regression analyses evaluated the association of extent of surgical resection, study publication year, tumor staging, propensity score matching, proportion of chemotherapy use, and proportion of pathological lymph node involvement with CSS and OS. Results: Thirty studies involving 29,511 patients were included (surgery group: 17,146 patients and SBRT group: 12,365 patients). There was a significant difference in favor of surgery vs. SBRT in the 3-year OS (HR = 1.35; 95% CI: 1.22-1.44; I2 = 66%) and 3-year CSS (HR = 1.23; 95% CI: 1.09-1.37; I2 = 17%), but not in the 3-year LC (HR = 0.97; 95% CI: 0.93-1.08; I2 = 19%). In the subgroup analysis for OS, no significant difference between surgery and SBRT groups was observed in the T1N0M0 subgroup (HR = 1.26; 95% CI: 0.95-1.68; I2 = 0%). In subgroup analysis for CSS, no significant difference was detected between the sublobar resection subgroup and the SBRT group (HR = 1.21; 95% CI: 0.96-1.53; I2 = 16%). Conclusions: Surgery generally resulted in better 3-year OS and CSS than did SBRT; however, publication bias and heterogeneity may have influenced these findings. In contrast, SBRT produced LC results similar to those of surgery regardless of the extent of surgical resection. These findings may have important clinical implications for patients with comorbidities, advanced age, poor pulmonary reserve, and other factors that may contraindicate surgery.

Abstract
Background For patients with locally advanced non-small cell lung cancer (NSCLC), the standard treatment is concurrent or sequential chemotherapy with radiotherapy. Most treatment schedules use radiotherapy with conventional fractionation; however, the application of hypofractionated radiotherapy (HYPO-RT) regimens is rising. A meta-analysis was performed to assess the efficacy and safety of chemotherapy combined with HYPO-RT and indirectly compare with the outcomes from previous studies employing concomitant conventional radiotherapy (CONV-RT). Methods Randomized controlled trials (RCTs) were identified on the electronic database sources through June 2020. Following the PRISMA guidelines, a meta-analysis was performed to assess if there were significant differences in the overall mortality (OM), local failure (LF), and disease progression (DP), comparing HYPO-RT-C vs. sequential chemotherapy followed HYPO-RT (HYPO-RT-S). To establish an indirect comparison with the current standard treatment, we calculate the risk ratio (RR) of the OM from RCTs using conventional chemoradiation, concurrent (CONV-RT-C), and sequential (CONV-RT-S), and compared with HYPO-RT. A P value <0.05 was considered significant. Results Two RCTs with a total of 288 patients were included. The RR for the OM, DP and LF at 3 year comparing HYPO-RT-C vs. HYPO-RT-S were 1.09 (95% CI: 0.96–1.28, P=0.17), 1.06 (95% CI: 0.82–1.23, P=0.610), and 1.06 (95% CI: 0.86–1.29, P=0.490), respectively. The late grade 3 pneumonitis and esophagitis had no significant difference between HYPO-RT groups. In the indirect comparison of RCTs using CONV-RT, the RR for the OM at 3 years was 1.03 (95% CI: 0.96–1.10, P=0.36) with no significant difference for the HYPO-RT arms 1.09 (95% CI: 0.96–1.28, P=0.17). Discussion HYPO-RT given with chemotherapy provides satisfactory OM, LF, and DP in locally advanced NSCLC with similar rates to the CONV-RT. These findings support HYPO-RT inclusion in future clinical trials as an experimental arm in addition to the incorporation of new strategies, such as immunotherapy.

Abstract
OBJECTIVES The management of Optic Nerve Sheath Meningiomas (ONSM) has suffered a significant shift due to new radiation techniques. However, there is no conclusive information on which approach presents better results in the literature. This meta-analysis aims to evaluate the outcomes of different radiotherapy (RT) modalities in the management of ONSM. METHODS A systematic review based on an electronic search was performed in MEDLINE, EMBASE, Cochrane, and Lilacs databases. Eligible studies included patients with ONSM treated with RT. Two reviewers independently assessed the eligibility of potential studies, extracted data, and performed the meta-analysis. Outcomes of interest were tumor control, visual acuity (VA), visual field, and complications. RESULTS Thirty-nine non-comparative studies involving 736 eyes with ONSM treated with RT were included. Six different techniques were studied: 2-dimensional RT (2DRT), 3D-conformal RT (3CRT), Stereotactic Fractionation RT (SFRT), stereotactic radiosurgery (SRS), intensity-modulated RT (IMRT), and proton beam therapy (PBT). With a mean follow-up period of 46 months, tumor control was 97,4% (95% CI: 98-100%). No difference was observed regarding the rate of final VA post-treatment among the modalities. The 3CRT showed substantially higher rates of complication than other techniques. CONCLUSIONS RT produces remarkable tumor control. New radiation modalities such as SFRT, IMRT, SRS, and PBT resulted in better therapeutic results with fewer complications than 2DRT and 3CRT. Thus, they should be the preferential choices for treating ONSM regardless of initial clinical presentation.

Abstract
OBJECTIVES Assess upfront Stereotactic radiosurgery (SRS) effectiveness for small cell lung cancer (SCLC) brain metastases (BM). Where possible, a comparison with whole-brain radiotherapy (WBRT) was performed. METHODS Following PRISMA and MOOSE guidelines, eligible studies were identified on Medline, Embase, Cochrane Library, and proceedings of annual meetings between inception and July 01, 2020. RESULTS Nine observational studies with 1638 patients were included. The median overall survival (OS) was 8.3 months (95% CI 7.1-9.5 months, I2 = 0%). OS rate at 12 months was 39% (95% CI 31-44%, I2 = 0%). The relative risk between SRS and WBRT for the OS at 12 months was 1.33 (95% CI 1.13-1.51, P = 0.0001). The projected OS for 6, 12, 18- and 24-months comparing SRS with WBRT was 67% vs. 57%, 39% vs. 29%, 22% vs. 15% and 15% vs 9%, favoring SRS (P < 0.001). The LC rate at 12 months was 93% (95% CI 91-94%, I2 = 0%). The distant brain failure rate (DBFR) at 12 months was 41% (95% CI 33-48%, I2 = 52%, P = 0.08). The SRS or WBRT as salvage treatment after upfront SRS was 32% and 19%, respectively. The freedom from neurologic death at 12 months was 87% (95% CI 84-89%). CONCLUSION Based on the pooling of a large sample of retrospective studies our meta-analysis suggests that for high selected SCLC patients with limited BM upfront SRS produces favorable lesion control and survival outcomes. These findings support the design of randomized clinical trial to confirm the role of SRS in this clinical scenario.

Abstract
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.

Abstract
Background The objective of this study was to assess the treatment outcomes and prognostic factors of elderly patients with locally advanced head and neck cancer (LAHNC) undergoing radiotherapy (RT). Materials and methods A retrospective cohort from a single institution, from 2000 to 2015, including patients older than 65 years old with LAHNC (stage III-IVa) treated by RT combined or not with chemotherapy (CRT). Univariate and multivariate analysis (MVA) were performed to identify prognostic factors associated with overall survival (OS), cancer-specific survival (CS), and locoregional control (LRC). A p-value < 0.05 was considered significant. Results 220 patients with LAHNC and > 65 years of age were identified. The median follow-up was 3.8 years, the 3/5 years estimated OS, CS, and LRC rate was 40%/30%, 49%/34%, 76%/45%, respectively. In the univariate analysis, clinical stage (III vs. IVa/b, p = 0.01), tumor stage (T1/2 vs. T3/4, p = 0.035), Karnofsky performance status (KPS, 60-70, p = 0.03) and tumor site (other than vs. hypopharynx, p = 0.0001) were associated with lower OS. Patients with clinical stage (III vs. IVa/b, p = 0.01), tumor stage (T1/2 vs. T3/4, p = 0.015), N stage (N0/1 vs. N2/3, p = 0.04), (KPS 60-70, p = 0.04) and tumor site (other than vs. hypopharynx, p = 0.0001) had worst CS. For the LRC, clinical stage (III vs. IVa/b, p = 0.02), tumor stage (T1/2 vs. T3/4, p = 0.02), treatment type (CRT vs. RT, p = 0.02), RT technique (IMRT vs. 2DRT/3DRT, p = 0.0001), and tumor site (other than vs. hypopharynx, p = 0.02) were significant. In the MVA, KPS maintained significant for OS and CS. For LRC, clinical stage (Iva/b, p = 0.007), tumor stage (T3/4, p = 0.047) and radiotherapy technique other than IMRT (p = 0.0001) were significant. Conclusion The OS, CS, and LRC were associated with several prognostic factors. The clinical performance was the main marker of OS and CS. Chemoradiation should be offered to selected elderly patients using IMRT to improve LRC.

Abstract
Gamma function is the standard methodology for comparing dose distributions. It is calculated in dedicated software, and its results verification is not performed. Thus we developed an automatic tool for patient-specific QA results verification through high accuracy machine learning (ML) models based on the radiomics characteristics extraction from gamma images. We used 158 patient-specific QA tests and extracted 105 radiomics features from each gamma image. Three random forest models were developed (ML I, ML II, and ML III). ML I and ML II verified the gamma image approval using criteria of 2%/2mm/15% threshold and 3%/3mm/15% threshold, respectively. ML III verified if the gamma analyzes software recommended protocol was followed to detect if the TPS grid modification step was done. The models were based on the most important features selected using the mean decreased impurity, and their performances were evaluated. ML I included 25 features. Its accuracy was 0.85 using the test set and 0.84 using dataset B. ML II included 10 features, and its accuracy with the test set was 0.98; the same value was achieved using the never seen data (dataset B). The First-order 10th percentile feature was identified as a feature strongly related to the approved classification. ML III selected 23 features with an accuracy of 0.99 for test set and 0.98 for dataset B. An automatic workflow example for gamma analyses QA results verification could be proposed combining the models to detect grid inconsistencies on software evaluation, followed by the test approval classification.

Abstract
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.

Abstract
The aim of this study was to evaluate whether there is a relationship between bleeding response and radiotherapy dose to palliate patients with local recurrence or progression of gastric cancer (GC). To this end, we conducted a systematic review and meta-analysis of observational studies that evaluated the bleeding response in patients with GC with local recurrence or progression. A meta-regression analysis between biological effective dose (BED) and bleeding response was performed, as was subgroup analysis to evaluate the outcome by BED level and radiotherapy (RT) technique. A p-value <0.05 was considered significant. Ten non-comparative retrospective studies and one prospective study were included. In general, RT was effective at controlling tumor bleeding, and the bleeding response rate was 0.77 (95% confidence interval (CI), 0.73-0.81). Meta-regression analysis demonstrated a linear correlation between BED Gy 10 and bleeding response (p=0<0001). Studies using conformational RT had a significant bleeding response rate compared to those using 2D (0.79; 95%CI, 0.74-0.84 vs 0.65; 95%CI, 0.56-0.75; p=0.021). In terms of the BED level, a significant difference in BR was identified on comparing BED Gy10 ≥40 (0.79; 95%CI, 0.7-0.8), BED Gy10 30-39 (0.79, 95%CI, 0.71-0.86), and BED Gy10 <30 (0.64; 95%CI, 0.5-0.7; p=0.0001). The mean survival time was 3.31 months (95%CI, 2.73-3.9) months, and the responders had a significantly longer survival (longer by 2.5 months) compared to the non-responders (95%CI, 1.7-3.3; p<0.0001). Palliative RT is effective at controlling bleeding due to local recurrence/progression from GC. Our findings reveal a relationship between BR and BED. BED <30 Gy 10 should not be recommended, and 3DRT should be indicated instead in order to improve the result.

Abstract
OBJECTIVES To assess the patterns of failure and prognostic factors in Brazilian patients with glioblastoma multiforme (GBM) treated with radiotherapy (RT) and concurrent and adjuvant temozolomide (TMZ). METHODS Patients with diagnosed GBM post-resection received postoperative RT. TMZ was administered concurrently at 75 mg/m2/day for 28 consecutive days and adjuvant therapy at 150-200 mg/m2/day for 5 days every 28 days. Radiographic failure was defined as any new T1-enhancing lesion or biopsy-confirmed progressive enhancement inside of the radiation field. When possible, patients with recurrence were salvaged with metronomic TMZ, either in combination with a local treatment or alone (surgery or re-irradiation). Several prognostic factors were evaluated for overall survival (OS). Univariate and multivariate analyses were performed to identify significant factors. A p-value <0.05 was considered significant. RESULTS This study included 50 patients. The median follow-up time was 21 months. The median RT dose was 60 Gy and all patients received concomitant TMZ. During follow-up, 41 (83.6%) failures were observed, including 34 (83%) in-field, 4 (9.7%) marginal, and 3 (7.3%) distant failures. Metronomic TMZ was used as salvage treatment in 22 (44%) cases and in combination with local treatment in 12 (24%) cases. The median OS and progression-free survival times for the entire cohort were 17 and 9 months, respectively. In univariate analysis, the following factors were significant for better OS: maximal surgical resection (p=0.03), Karnofsky Performance Score (KPS)>70 at diagnosis (p=0.01), metronomic TMZ treatment (p=0.038), recursive partitioning analysis class III (p=0.03), and time to failure >9 months (p=0.0001). In multivariate analysis, the following factors remained significant for better OS: metronomic TMZ (p=0.01) and time to failure >9 months (p=0.0001). CONCLUSION The median OS of Brazilian patients with GBM treated with RT and TMZ was satisfactory. Although TMZ therapy has become the standard of care for patients with newly diagnosed GBM, the recurrence rate is extremely high. Metronomic TMZ as salvage treatment improved survival in these patients.

Abstract
OBJECTIVE To build a model to evaluate the impact of salvage radiotherapy (SRT) in men with PSA rise or persistent PSA after undergoing radical prostatectomy (RP). MATERIALS AND METHODS The study included 107 node-negative patients treated with SRT after RP at a single institution. Patients received SRT for either prostate-specific antigen (PSA) rising, or PSA persistence after RP. All patients received local radiation to the prostate / seminal vesicle bed. The primary measured outcome was the biochemical recurrence (BCR) free survival. Multivariable Cox regression analysis was used to develop a risk-stratification group to identify predictive factors associated with the probability of BCR at 5yr. RESULTS At a median follow-up of 52 months, the BCR free survival rate and overall survival in 5 years was 73% and 94%, respectively. At multivariable analysis, pre-SRT PSA level > 0.35ng / mL (p = 0.023), negative margins (p = 0.038), and seminal vesicles invasion (p = 0.001) were significantly associated with BCR free survival. Three risk groups using regression analysis for SRT administration was built. Low-, intermediateand the high-risk groups had a BCR free survival in 5-years of 96%, 84%, and 44% (p = 0.0001), respectively. CONCLUSIONS We developed a risk group stratification to show the impact of SRT based on prostate cancer characteristics. SRT showed to be extremely beneficial for patients with low- and intermediate-risk tumors. Moreover, the risk-group built could identify patients classified as high-risk who might benefit from more aggressive treatment for SRT.

Abstract
Objetivo:
Analisar os últimos 20 anos do modelo de remuneração do SUS no setor de radioterapia tentando demonstrar que o modelo vigente não leva em consideração variáveis importantes para sua adequação e precisa ser melhorado.
Materiais e métodos
Estudo observacional do tipo transversal que incluiu a coleta de dados referente ao orçamento e ao número de procedimentos em radioterapia do Brasil no período compreendido entre 1995-2015. O modelo foi testado para avaliar a relação com a incidência da doença e a inflação. As variáveis foram testadas para relação linear, cúbica, exponencial e logarítmica. Para medir a força de associação entre as variáveis um R square foi calculado, sendo significativo os valores > 0,75 e p < 0.05.
Resultados
Observou-se um aumento significativo tanto na quantidade, quanto no orçamento aprovado, sendo este aumento linear tanto na quantidade de procedimentos (R=0.94 e p<0.05) quanto nos valores aprovados de procedimentos realizados nos últimos 20 anos (R= 0.82 e p<0.05). Apesar do aumento de gasto do ministério da saúde em quantidade e valor terem sidos de 4,5 e 7,5 vezes em 20 anos, apenas com exceção do ano de 2010, todos os outros anos o aumento não foi dado na fonte, apenas no teto ou pela criação de novos serviços. Não houve qualquer relação com a incidência (p>0.05) nem com a inflação (p>0.05). Houve um déficit de repasse de R$ 90.000.000,00 não corrigidos pela inflação acumulada nos últimos 5 anos e de aproximadamente R$ 350.000.000,00 em 20 anos.
Conclusão
Nos últimos 20 anos o ministério da saúde aumentou a quantidade tanto de procedimentos quanto de orçamento para a radioterapia de forma constante e linear, mas o modelo não atende as necessidades da população brasileira. Pois não leva em consideração a incidência, a inflação e o aumento dado não é fornecido na fonte geradora do procedimento.

Abstract
PURPOSE The aim of this quasi-experimental study is to evaluate a novel technique for an outpatient application of formalin for chronic rectal bleeding after prostate irradiation. METHODS This is a quasi- experimental clinical trial developed between January 2010 and July 2015, including 35 patients with chronic radiation rectitis (CRP) due to a previous prostate radiation course. The study's eligibility was (1) completed external beam radiation therapy for prostate carcinoma >6 months previously, (2) rectal bleeding, defined as a frequency of >1× per week and/or needing of blood transfusions, and (3) diagnosis of chronic proctitis at colonoscopy. The 5% formalin application was performed by a custom applicator, which requires neither anesthesia nor sigmoidoscopy. The endpoint of the study was bleeding cessation and hemoglobin level. RESULTS The onset of bleeding due to chronic rectitis was 12 months (6-36). During a median follow-up of 24 months, the rate of overall efficacy was 94%. The sustained complete response in 1 and 2 years was 80% and 73%, respectively. The Hb mean pre- and post-treatment differed significantly (12.2 vs 14.4, p = 0.0001). The rates of blood transfusion differed significantly, pre- and post-treatment (17% vs 5.7%, p = 0.031). CONCLUSION The technique is very effective and safe, resulting to a significant improvement of hemoglobin levels and quality of life scores. Further studies are warranted to compare this technique with other treatment options for chronic radiation-induced rectal bleeding.

Abstract
In this systematic review, we evaluated studies involving adjuvant and primary topical treatment for ocular surface squamous neoplasia (OSSN). The findings were: (i) adjuvant 5-fluorouracil (5-FU) reduces the risk of relapse after surgical excision with mild side effects [level Ib, grade of recommendation (GR) A]. (ii) Primary topical mitomycin (MMC) produces a high rate of complete response, low recurrence rate, and mild side effects (level Ib, GR A). (iii) Primary chemotherapy versus adjuvant chemotherapy produce similar rates of recurrence, with no significant difference (level IIb, GR B). (iv) Adjuvant 5-FU versus MMC showed no significant differences, with mild side effects in both groups and a better toxicity profile for MMC (level III, GR C). (v) Primary topical 5-FU versus MMC versus interferon (IFN) showed similar rates of tumor recurrence, mild side effects for all drugs, and more severe side effects in the 5-FU arm, followed successively by MMC and IFN (level III, GR C).

Abstract
AIM To report the treatment results of a retrospective cohort of prostate cancer patients treated with Hypo-RT with a high equivalent biological effective dose (BED). BACKGROUND Hypofractionated radiotherapy (Hypo-RT) has gained popularity and interest in the treatment of prostate cancer. However, there are few experiences with adequate follow-up reporting treatment results using high equivalent dose with Hypo-RT. MATERIALS AND METHODS We assigned 149 men with low-, intermediate- and high-risk prostate cancer to receive Hypo-RT with a total dose of 69 Gy/23 fractions. Late gastrointestinal (GI) and genitourinary (GU) toxicity were prospectively evaluated according to modified RTOG criteria. Biochemical no evidence of disease (bNED) was defined as the nadir prostate-specific antigen level plus 2 ng/mL. RESULTS The median follow-up was 53 months. For the entire cohort, the 5-year bNED rate was 94.6%, and for low-, intermediate- and high-risk patients the 5-year bNED was 100%, 96.4%, and 86% (p = 0.007), respectively. The 5-year overall survival rate was 92%. Only 1 patient died from the disease at 48 months after treatment, giving a 5-year cancer-specific survival of 98%. The worst grade ≥2 rate GI and GU toxicity was 13.4% and 14%, respectively. No grade >3 toxicity was observed. The presence of grade ≥2 GI and GU toxicity at the last follow-up was only 1.3% and 3%, respectively. CONCLUSIONS Hypo-RT (69 Gy/23 fractions) with a high equivalent BED produces excellent rates of biochemical control for low, intermediate and high-risk prostate cancer. The long term GU and GI toxicity rates were considered low and acceptable.

Abstract
BACKGROUND The objective of this article was to report the results from a randomized clinical trial comparing intensity-modulated radiotherapy (IMRT) with 3-dimensonal conformal radiotherapy (3DCRT) for the treatment of prostate cancer on a hypofractionated schedule. METHODS The authors randomly assigned 215 men who had localized prostate cancer to receive hypofractionated radiotherapy to a total dose of 70 grays (Gy) in 25 fractions (at 2.8 Gy per fraction) using either IMRT or 3DCRT. Acute and late gastrointestinal (GI) and genitourinary (GU) toxicity were prospectively evaluated according to modified Radiation Therapy Oncology Group criteria. Biochemical control was defined according to the Phoenix criteria (prostate-specific antigen nadir + 2 ng/mL). RESULTS In total, 215 patients were enrolled in the IMRT group (n = 109) or the 3DCRT group (n = 106). The 3DCRT arm had a 27% rate of grade ≥ 2 acute GU toxicity compared with a 9% rate in the IMRT arm (P = .001) and a 24% rate of grade ≥ 2 acute GI toxicity compared with a 7% rate in the IMRT arm (P = .001). The maximal rate of grade ≥2 late GU toxicity during the entire period of follow-up was 3.7% in the IMRT group versus 12.3% in the 3DCRT group (P = .02). The maximal rate of grade ≥2 late GI toxicity during the entire follow-up was 6.4% in the IMRT group versus 21.7% in the 3DCRT group (P = .001). The 5-year rate of freedom from biochemical failure was 95.4% in the IMRT arm and 94.3% in the 3DCRT arm (P = .678). CONCLUSIONS IMRT reduced the delivery of significant radiation doses to the bladder and rectum using a similar target volume. This dosimetric advantage resulted in a lower rate of acute/late grade ≥ 2 GI and GU toxicity for IMRT compared with 3DCRT. Cancer 2016;122:2004-11. © 2016 American Cancer Society.

Abstract
OBJECTIVE To analyze and compare quality of life (QoL) in adults and elderly patients with rheumatoid arthritis (RA). METHODS This was a cross-sectional quantitative study. The tools include the Medical Outcomes Study Short Form-36 (SF-36), the Disease Activity Score 28 (DAS-28), the Assessment Health Questionnaire (HAQ), the Beck Depression Inventory (BDI) and the 6-Minute Walk Test (6MWT). Data analysis was done by descriptive statistics, Student's t test and linear regression test, with significance level of p <0.05. RESULTS The sample consisted of 99 patients diagnosed with RA, divided into adults and elderly. Those considered adults were 18-59 years-old and those with 60 years or older where considered elderly. In SF-36, the groups showed the pain domain as the most compromised and the emotional aspects domain as the less compromised. Both showed moderate level of disease activity and mild disability. Applying the t test, it was found that there was no significant difference between groups with respect to QoL, functional ability, depression and disease activity. The difference was significant in the 6MWT, in which the elderly achieved an average of 330.8 m, and the adults, 412.2 m (p=0.000). In linear regression, a significant correlation (r=-0.31) between the 6MWT and increasing age was noted. CONCLUSION QoL and functional capacity in RA were affected in adults and the elderly. How-ever, the results showed no significant difference between groups, with the exception of the 6MWT.

Abstract
Purpose To compare the acute toxicities in radical treatment of prostate cancer between conventional schedule (C-ARM) with 78 Gy/39 fractions and hypofractionation conformal treatment (H-ARM) with 69 Gy/23 fractions. Methods and material This prospective double arm study consisted of 217 patients with prostate cancer, 112 in H-ARM and 105 in C-ARM arm. C-ARM received conventional six- field conformal radiotherapy with 78 Gy in 39 fractions while H-ARM received hypofractionation with 69 Gy in 23 fractions. Weekly assessment of acute reactions was done during treatment and with one, and 3 months using RTOG scale. Univariated analysis was performed to evaluate differences between the incidences of acute reaction in the treatment arms. Variables with p value less than 0.1 were included in the multivariated logistic regression. Results There was no difference between H-ARM versus C-ARM for severity and incidence in genitourinary (GU) and gastrointestinal (GI) acute toxicity. During the treatment comparing H-ARM with C-ARM no differences was observed for GI toxicity (grade 0–3; H-ARM = 45.5%, 34%, 18.7% and 1.8% versus C-ARM = 47.6%, 35.2%, 17.2% and 0). For acute GU toxicity no difference was detected between H-ARM (grade 0–3; 22.3%, 54.5%, 18.7% and 4.5%) and C-ARM (grade 0–3; 25.8%, 53.3%, 17.1% and 3.8%). At the 3- months follow-up, persistent Grade > =2 acute GU and GI toxicity were 2.5% and 1.8% in H-ARM versus 5.7% and 3% in C-ARM (p > 0.05). In univariated and multivariated analyses, there was not any dosimetric predictor for GI and GU toxicity. Conclusions Our data demonstrate that hypofractionated radiotherapy achieving high biological effective dose using conformal radiotherapy is feasible for prostate cancer, being well tolerated with minimal severe acute toxicity.

Abstract
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 (OR = 0.73; 95% CI: 0.57-0.97; p = 0.01), especially among the patients showing a complete response after induction chemotherapy (OR = 0.68; 95% CI: 0.50-0.93; p = 0.02) and in those submitted to PCI after that treatment (OR = 0.68; 95% CI: 0.49-0.94; p = 0.03). That decrease did not correlate with the stage of the disease: limited disease (OR = 0.73; 95% CI: 0.55-0.97; p = 0.03); and extensive disease (OR = 0.48; 95% CI: 0.26-0.87; p = 0.02). CONCLUSIONS Our findings suggest that PCI decreases mortality in patients with SCLC, especially in those showing a complete response after induction chemotherapy and in those submitted to PCI after that treatment, regardless of the stage of the disease.

PURPOSE To determine in a meta-analysis whether prostate cancer-specific mortality (PCSM), biochemical or clinical failure (BCF), and overall mortality (OM) in men with localized prostate cancer treated with conformal high-dose radiotherapy (HDRT) are better than those in men treated with conventional-dose radiotherapy (CDRT). METHODS AND MATERIALS The MEDLINE, Embase, CANCERLIT, and Cochrane Library databases, as well as the proceedings of annual meetings, were systematically searched to identify randomized, controlled studies comparing conformal HDRT with CDRT for localized prostate cancer. RESULTS Five randomized, controlled trials (2508 patients) that met the study criteria were identified. Pooled results from these randomized, controlled trials showed a significant reduction in the incidence of PCSM and BCF rates at 5 years in patients treated with HDRT (p = 0.04 and p < 0.0001, respectively), with an absolute risk reduction (ARR) of PCSM and BCF at 5 years of 1.7% and 12.6%, respectively. Two trials evaluated PCSM with 10 years of follow up. The pooled results from these trials showed a statistical benefit for HDRT in terms of PCSM (p = 0.03). In the subgroup analysis, trials that used androgen deprivation therapy (ADT) showed an ARR for BCF of 12.9% (number needed to treat = 7.7, p < 0.00001), whereas trials without ADT had an ARR of 13.6% (number needed to treat = 7, p < 0.00001). There was no difference in the OM rate at 5 and 10 years (p = 0.99 and p = 0.11, respectively) between the groups receiving HDRT and CDRT. CONCLUSIONS This meta-analysis is the first study to show that HDRT is superior to CDRT in preventing disease progression and prostate cancer-specific death in trials that used conformational technique to increase the total dose. Despite the limitations of our study in evaluating the role of ADT and HDRT, our data show no benefit for HDRT arms in terms of BCF in trials with or without ADT.

Abstract
PURPOSE To determine, in a meta-analysis, whether gynecomastia and breast pain rates in men with prostate cancer treated with androgen deprivation therapy (ADT) are reduced if treated with prophylactic radiotherapy (RT) or tamoxifen (TMX). METHODS AND MATERIALS The MEDLINE, EMBASE, CANCERLIT, and Cochrane Library databases, as well as proceedings of annual meetings, were systematically searched to identify randomized, controlled studies comparing RT or TMX with observation for men with prostate cancer using ADT. RESULTS Six RCTs (three RT trials and three TMX trials, N = 777 patients total) were identified that met the study criteria. Pooled results from these RCTs comparing RT vs. observation showed a significant reduction in the incidence of gynecomastia and breast pain rates in patients treated with RT (odds ratio [OR] = 0.21, 95% confidence interval [CI] = 0.12-0.37, p < 0.0001, and OR = 0.34, 95% CI 0.20-0.57, p < 0.0001, respectively). Use of RT resulted in an absolute risk reduction (ARR) of 29.4% and 19.9%, with a number needed to treat (NNT) of 3.4 and 5 to avoid one case of gynecomastia and breast pain, respectively. Pooled results from trials comparing TMX vs. observation showed a statistical benefit for breast pain and gynecomastia in favor of TMX arms (OR = 0.04, 95% CI = 0.02-0.08, p < 0.0001 and OR = 0.07, 95% CI = 0.0-0.14, p < 0.00001). TMX resulted in an ARR = 64.1% and 47.6%, with an NNT of 1.56 and 2.1 to avoid one case of gynecomastia and breast pain, respectively. Considering adverse effects, TMX was 6 times more adverse effects than RT. CONCLUSIONS Our data have shown that both TMX and RT prevented gynecomastia and breast pain in patients with prostate cancer receiving ADT for prostate cancer. Although TMX was two times more effective in preventing gynecomastia, RT should represent an effective and safe treatment option, to take into account mainly in patients with cardiovascular risk factors or thrombotic diathesis.

Abstract
PURPOSE To evaluate whether the risk of local recurrence depends on the biologic effective dose (BED) or fractionation dose in patients with resectable rectal cancer undergoing preoperative radiotherapy (RT) compared with surgery alone. METHODS AND MATERIALS A meta-analysis of randomized controlled trials (RCTs) was performed. The MEDLINE, Embase, CancerLit, and Cochrane Library databases were systematically searched for evidence. To evaluate the dose-response relationship, we conducted a meta-regression analysis. Four subgroups were created: Group 1, RCTs with a BED >30 Gy(10) and a short RT schedule; Group 2, RCTs with BED >30 Gy(10) and a long RT schedule; Group 3, RCTs with BED ≤ 30 Gy(10) and a short RT schedule; and Group 4, RCTs with BED ≤ 30 Gy(10) and a long RT schedule. RESULTS Our review identified 21 RCTs, yielding 9,097 patients. The pooled results from these 21 randomized trials of preoperative RT showed a significant reduction in mortality for groups 1 (p = .004) and 2 (p = .03). For local recurrence, the results were also significant in groups 1 (p = .00001) and 2 (p = .00001).The only subgroup that showed a greater sphincter preservation (SP) rate than surgery was group 2 (p = .03). The dose-response curve was linear (p = .006), and RT decreased the risk of local recurrence by about 1.7% for each Gy(10) of BED. CONCLUSION Our data have shown that RT with a BED of >30 Gy(10) is more efficient in reducing local recurrence and mortality rates than a BED of ≤ 30 Gy(10), independent of the schedule of fractionation used. A long RT schedule with a BED of >30 Gy(10) should be recommended for sphincter preservation.

Abstract
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.
