RESUMO

OBJECTIVE: To evaluate the correlation between socioeconomic and healthcare factors and cervical cancer mortality rates, as well as the accessibility to prevention and treatment across Brazilian states and macroregions. The aim is to highlight the multifaceted challenge of addressing cervical cancer mortality, particularly in low- and middle-income countries. METHODS: This cross-sectional study analyzed public data from the Brazilian National Institute of Cancer (INCA), the National Institute of Geography and Statistics (IBGE), and the Brazilian Ministry of Health. Data were collected on indicators such as the Human Development Index (HDI), physician density, average household income, human papillomavirus (HPV) vaccine coverage, Pap smear screening rates, radiotherapy machine density, and non-White population rates by state and macroregion across Brazil. Spearman's rank correlation test and simple linear regression analysis were employed. RESULTS: Cervical cancer mortality rates are statistically lower in women with health insurance, positive self-perception of health, located in states with a higher HDI, per capita household income, density of physicians, and radiotherapy machines per 1000 inhabitants. In contrast, mortality rates proportionally increase according to poverty levels, as expected, and rates of non-White population. Considering public health, HDI scores significantly affected Pap smear test coverage, the number of radiotherapy machines, and HPV vaccine uptake. The North and the Southeast regions have, respectively, the lowest and the highest socioeconomic indicators, proportional to their mortality rates. No significant correlation was found between mortality rates and HPV vaccine or Pap smear coverage. CONCLUSIONS: Cervical cancer mortality in Brazil is significantly influenced by socioeconomic and healthcare disparities. This study provides a data-driven basis for public health strategies that address both medical and social determinants of health.

RESUMO

OBJECTIVE: To evaluate the influence of the personal experience of female obstetricians and gynaecologists (Obst/Gyns) who utilise contraceptive methods on the provision of these methods. METHODS: An anonymous online web-based survey was carried out with female Obst/Gyns. The instrument contained questions about their current and previous contraceptive methods use, factors that influenced the choice and satisfaction with the ongoing method, as well as the occurrence of adverse events. They were also asked whether the experience of any adverse events influenced their decision in prescribing any particular contraceptive method. RESULTS: 476/9000 (5.3%) female Obst/Gyns answered the survey. The most common contraceptive in use was the 52-mg levonorgestrel-intrauterine device (52-mg LNG-IUD) (34%), followed by non-Long-Acting Reversible Contraception hormonal methods (21.2%). More than half of the respondents (57.6%) reported having some adverse effects and 18.7% reported that the personal experience of an adverse effect with the use of a contraceptive method influenced the prescription of that method. CONCLUSION: Half of female Obst/Gyns encountered adverse events linked to contraceptive usage. Additionally, almost one-fifth believe that their own encounter with adverse effects from a contraceptive method impacts their decision to prescribe the same method.


Almost one-fifth of the female obstetrics and gynaecologists that answered the online survey reported that the personal experience of an adverse effect with the use of a contraceptive method influenced the prescription of that method.

RESUMO

Women at high inherited risk of ovarian cancer are offered risk-reducing salpingo-oophorectomy (RRSO) from age 35 to 45 years. Although potentially life-saving, RRSO may induce symptoms that negatively affect quality of life and impair long-term health. Clinical care following RRSO is often suboptimal. This scoping review describes how RRSO affects short- and long-term health and provides evidence-based international consensus recommendations for care from preoperative counselling to long-term disease prevention. This includes the efficacy and safety of hormonal and non-hormonal treatments for vasomotor symptoms, sleep disturbance and sexual dysfunction and effective approaches to prevent bone and cardiovascular disease.

RESUMO

The Heavy menstrual bleeding: Evidence-based Learning for best Practice (HELP) Group developed an educational website about heavy menstrual bleeding (HMB). The "HMB improving Outcomes with Patient counseling and Education" (HOPE) project examined the website's impact on women's knowledge, confidence, and consultations with healthcare providers (HCPs). HOPE was a quantitative online survey of gynecologists and women with HMB in Brazil. After an initial consultation, patients had unlimited access to the website and completed a survey. HCPs also completed a survey about the sconsultation. After a second consultation, HCPs and patients completed another survey. HCP surveys assessed their perception of patients' awareness, understanding, and willingness to discuss HMB. Patient surveys assessed their knowledge, experience, and confidence in discussing HMB. Forty HCPs recruited 400 women with HMB. Based on HCP perceptions at the first consultation, 18 percent of patients had "good knowledge" or "very good knowledge" of HMB, increasing to 69 percent after patients had visited the website. Before and after visiting the website, 34 percent and 69 percent of patients, respectively, regarded their HMB knowledge as "goo.d" Additionally, 17 percent of women reported their anxiety as "highest" during the first consultation; this decreased to 7 percent during the second consultation. After visiting the HELP website, patients' knowledge of HMB improved and they were less anxious.

RESUMO

OBJECTIVE: To assess the provision of contraceptives by Brazilian obstetricians and gynaecologists (Obst/Gyns) during medical consultation and associated factors. METHODS: An anonymous online survey was conducted with Obst/Gyns regarding age, gender, training, method counselling about and provision of long-acting reversible contraception (LARC). RESULTS: Of 16,000 Obst/Gyns, 610 (3.8%) answered the survey. After multiple regression analysis, female Obst/Gyns (reference) (OR male was 0.53 [95%CI 0.28-0.98], p = 0.044) and Obst/Gyns aged between 20 and 39 were more likely to provide an IUD. For hormonal-IUDs, Obst/Gyns who had had theoretical training in hormonal-IUD insertion (reference no training) (OR = 2.13 [95%CI 1.14-3.99], p = 0.018), those who work in a private facility or public hospital, and those that allowed more time during consultations (reference) (OR short time = 0.33 [95%CI 0.17-0.63], p < 0.001) were more likely to provide them. Obst/Gyns who were hands-on trained were more likely to provide subdermal implant (OR = 2.04 [95%CI 1.45-2.87], p < 0.001). CONCLUSIONS: There is a gap between theoretical and practical training received by this cohort of Obst/Gyns regarding LARCs, mainly contraceptive implants and hormonal-IUDs. The identification of barriers to offering contraceptives is essential to providing client-centred contraceptive care.


There is a gap between the theoretical and practical training received by Brazil-based Obst/Gyns regarding LARC methods, mainly subdermal implants and hormonal-IUDs. The identification of barriers is essential to providing client-centred contraceptive care.

RESUMO

PURPOSE: Mindfulness-based programs can reduce stress and help practitioners to have positive attitudes in their daily lives. This randomized controlled trial evaluated the impact of brief Mindfulness interventions on quantitative and qualitative stress parameters in patients undergoing imaging-guided breast biopsies. METHODS: Eighty-two women undergoing percutaneous imaging-guided breast biopsy were randomized into two groups: MBI group or standard care group. One week before the biopsy procedure, on the waiting room and during the biopsy procedure, the MBI group was exposed to mindfulness techniques and the standard care group received supportive dialogue from the biopsy team. Participants completed questionnaires measuring depression, anxiety and stress, demographics, and medical history, besides evaluating their pain experience through a visual analogue scale for pain and had their systolic and diastolic blood pressure, initial and final temperate, heart rate, oxygen saturation, and salivary cortisol measured. RESULTS: Participation in the mindfulness intervention group was associated with reduced levels of perceived stress, blood pressure, heart rate, and oxygen saturation compared to participation in the standard care group (P values < 0.05). No difference was observed regarding salivary cortisol levels, peripheral temperature, and pain perception between the two studied groups. CONCLUSION: Results indicate that an extremely brief mindfulness intervention is a feasible intervention, suggesting that Mindfulness-based programs may be beneficial to reduce discomfort in acutely stressful settings.

RESUMO

OBJECTIVE: To understand the extent to which barriers and misperceptions about intrauterine contraception (IUC) remain among Brazilian gynaecologists, particularly for nulliparous women. METHODS: An online survey was developed to assess Brazilian gynaecologists' knowledge and attitudes towards IUC. Data collected included demographic and professional data, main barriers when considering IUC for women in general and/or nulliparous women, attitudes towards inclusion of IUC in contraceptive counselling, and opinions on what could increase IUC prescription for nulliparous women. A question regarding knowledge about WHO medical eligibility criteria (WHO MEC) was also included in the survey. RESULTS: 101 gynaecologists completed the survey. The insertion rate in nulliparous women was 79.2%. Brazilian gynaecologists were more likely to consider IUC in counselling or provide it on request for parous than for nulliparous women (p<0.05) and perceived more complications in nulliparous women. 74.2% of gynaecologists recognised a higher risk of pelvic inflammatory disease (PID)/infertility associated with IUC use in nulliparous women than in parous women. Difficult and painful insertion were also relevant for 83.2% and 77.3% of the gynaecologists, respectively. Respondents showed a high level of awareness of the WHO MEC classification. CONCLUSIONS: The three most commonly reported barriers to considering IUC as a contraceptive option for nulliparous woman were concerns about PID and difficult or painful insertion. The challenge is to ensure that gynaecologists understand the evidence and do not disregard IUC as a potential option for nulliparous women.

RESUMO

OBJECTIVES: This study sought to understand women's perceived barriers to the use of hormonal and non-hormonal intrauterine contraception in Latin America. METHODS: We developed an online survey for women in Argentina, Brazil, Colombia and Mexico who were seeking contraception. The questions aimed at evaluating patient awareness of negative stories and statements, as well as perceived barriers to the copper intrauterine device (IUD) and the levonorgestrel-releasing intrauterine system (LNG-IUS). RESULTS: The survey was mailed to 2300 women. A total of 1953 responses were received from Argentina (n = 465), Brazil (n = 380), Colombia (n = 613) and Mexico (n = 495). More women reported having heard negative stories about the copper IUD than about the LNG-IUS. More women believed that the copper IUD, rather than the LNG-IUS, was suitable only for those who had already had children. More women believed that weight gain (14.3% vs. 38.2%; p < 0.001), mood swings (14.1% vs. 38.7%; p < 0.001) and infertility (16.3% vs. 19.9%; p = 0.016) were possible side effects of the LNG-IUS. By contrast, more women believed that abortion (36% vs. 22.7%; p < 0.001), pelvic infections (42.1% vs. 15.7%; p < 0.001) and ectopic pregnancy (43.5% vs 23.5%; p < 0.001) were side effects more associated with the copper IUD. More believed the copper IUD was associated with less pain during placement and removal compared with the LNG-IUS (42.8% vs. 31.2%; p < 0.001). The perception of increased risk of contracting a sexual transmitted disease did not differ between the methods (IUD vs. LNG-IUS, 21.7% vs. 20.3%; p = 0.388). CONCLUSIONS: Respondents to a web-based survey in four Latin American countries have misperceptions regarding the adverse effects and risks of intrauterine contraception, which may hamper the use of these safe and efficient contraceptive methods. Education about the true risks and benefits involved is fundamental to improving patient acceptance and compliance as well as reducing unplanned pregnancies and unsafe abortions.

RESUMO

OBJECTIVE: This study assesses TRAIL-R2 (TNF-related apoptosis-inducing ligand receptor 2) and BCL2 (B cell CLL/lymphoma 2) expression as well as CpG island methylation within the TRAIL-R2 promoter in ovarian serous tumors and primary and metastatic serous EOC (epithelial ovarian cancer). METHODS: RNA and DNA were obtained from women with normal ovarian tissues (n = 18), ovarian serous cystadenoma tumors (n = 11) and serous EOC (n = 16) using Trizol®. Quantitative PCR was performed to quantify the relative levels of TRAIL-R2 and BCL2. The methylation frequency of the TRAIL-R3 promoter was assessed using a methylation-specific PCR assay after DNA bisulfite conversion. Differences between the groups were evaluated using the χ (2), Mann-Whitney U or Kruskal-Wallis tests, as indicated. RESULTS: We identified TRAIL-R2 and BCL2 mRNA expressed in all ovarian tumor groups, and there were significant differences between the groups. Both genes had low expression levels in ovarian serous cystadenoma and primary EOC tumors when compared with metastatic EOC. Methylation of the TRAIL-R2 promoter was frequently observed in all groups; however, there were no statistically significant associations. CONCLUSIONS: Primary EOC is associated with lower TRAIL-R2 and BCL2 expression levels, while metastatic EOC is associated with higher expression of these genes. Promoter DNA methylation was not related to this finding, suggesting there are other mechanisms involved in transcriptional control.

RESUMO

Objective: Endometrial cancer (EC) is a heterogeneous disease with recurrence rates ranging from 15 to 20%. The discrimination of cases with a worse prognosis aims, in part, to reduce the length of surgical staging in cases with a better prognosis. This study aimed to evaluate the association between Insulin-like growth factor II mRNA-binding protein 3 (IMP3) expression and prognostic and morphological factors in EC. Methods: This retrospective, cross-sectional, analytical study included 79 EC patients - 70 endometrioid carcinoma (EEC) and 9 serous carcinoma (SC) - and 74 benign endometrium controls. IMP3 expression was evaluated by immunohistochemistry-based TMA (Tissue Microarray), and the results were associated with morphological and prognostic factors, including claudins 3 and 4, estrogen and progesterone receptors, TP53, and KI67. Results: IMP3 expression was significantly higher in SC compared to EEC in both extent (p<0.001) and intensity (p=0.044). It was also significantly associated with worse prognostic factors, including degree of differentiation (p=0.024, p<0.001), staging (p<0.001; p<0.001) and metastasis (p=0.002; p<0.001). IMP3 expression was also significant in extent (p=0.002) in endometrial tumors compared with controls. In addition, protein TP53 and KI67 showed significant associations in extent and intensity, respectively. Conclusion: IMP3 expression was associated with worse prognostic factors studied. These findings suggest that IMP3 may be a potential biomarker for EC poorer prognosis.

RESUMO

Objective: Fertility preservation is a priority in oncology for female cancer patients. However, there is a lack of communication between infertility specialists and oncologists. This study aimed to evaluate infertility specialists' perceptions and experiences regarding fertility preservation. Methods: Conduct an online survey to profile infertility specialists. Participants were infertility affiliated with the Brazilian Federation of Gynecology and Obstetrics Associations (FEBRASGO). The specialists received an online survey, which response rate were 30.9%, most of whom were in southern and southeastern. The survey consisted on 14 questions about the infertility specialists' location, techniques in clinical practice, treatment successful rate, patients idea, etc. Results: The average experience in human reproduction were 15.5 ± 10.2 years (mean ± standard deviation, range 1-40). Among reproductive-aged female cancer patients recommended for fertility preservation, 60.3 ± 28.8% (range 10-100%) underwent preservation procedures. Main barriers were cost (41%), oncologists' knowledge or acceptance (35%) and accessibility (9%). Most infertility specialists (58%) considered 40 years the limit for fertility preservation. Leukemia, lymphoma, breast and ovarian cancers were prioritized for fertility preservation, while lung, thyroid, gastric, and brain cancers were less relevant. Conclusion: This is the first Brazilian study about infertility specialists' perceptions on oncology patients access to fertility preservation. These patients primarily receive treatment in the public health system, while infertility specialists mainly work in the private healthcare. This healthcare mode is currently fragmented, but integrating these experts is enhancing patient access to fertility preservation. Studies on this topic are still warranted.

RESUMO

BACKGROUND: Digital technology and gamified apps can be useful in the health care context. Gamification uses technology to influence users' actions and motivations through experiences that resemble games. Patient adherence to the enhanced recovery after surgery (ERAS) program is crucial for achieving early recovery after surgery and continuous monitoring is essential for obtaining good results. OBJECTIVE: This study aimed to describe the development and validation of a mobile app for enhanced recovery after surgery (MobERAS), a gamified mobile health app for telemonitoring patients in the postoperative period based on the ERAS program, and to evaluate its functionality and usability and the experience of patients, health care professionals, and computer professionals with its use. METHODS: We developed MobERAS for postoperative telemonitoring, with active participation of patients in the process, and offering availability of real-time information for the health team. The app development process included idealization, interdisciplinary team formation, potential needs assessment, and product deployment. Usability tests were conducted throughout the development process with improvements, technical adjustments, and updates. After finalization, comprehensive verification tests were performed. The parameters evaluated are those that can influence the length of hospital stay, such as nausea, vomiting, pain scales, return to normal gastrointestinal function, and thromboembolic events. MobERAS was designed to be downloaded by users on their phones, tablets, or other mobile devices and to provide postoperative data. The app has a GPS that monitors the patient's walking time and distance and is connected to a virtual database that stores the collected data. RESULTS: Women undergoing medium and major gynecologic oncologic surgeries were included. We included 65 patients with an average age of 53.2 (SD 7.4, range 18-85) years. The time of use ranged from 23.4 to 70 hours (mean 45.1, SD 19.2 hours). Regarding adherence to the use of MobERAS, the mean fill rate was 56.3% (SD 12.1%, range 41.7%-100%), and ambulation data were obtained for 60 (92.3%) of the 65 patients. The researcher had access to the data filled out by the patients in real time. There was good acceptance of the use of MobERAS by the patients, with good evaluation of the app's usability. MobERAS was easy to use and considered attractive because of its gamified design. The app was rated as good or very good in all items by health care professionals (n=20) and professionals specializing in technological innovation (n=10). CONCLUSIONS: MobERAS is easy to use, safe, well accepted by patients, and well evaluated by experts. It can be of great use in clinical surgical practice and an important tool for greater engagement of patients and health care professionals with the ERAS program.

RESUMO

Among gynecological malignancies, ovarian cancer (OC) presents the most challenging diagnostic scenario. Despite exhaustive efforts, up to 90 % of patients treated with taxane/platinum-based chemotherapy experience relapse, leading to poor survival rates. Identifying new molecular markers that can characterize disease aggressiveness, chemoresistance, recurrence risk, and metastasis is crucial. This study aimed to assess the susceptibility of three ovarian tumor cell lines (TOV-21G, SKOV-3, and OV-90) to cisplatin and paclitaxel, and to investigate the influence of these treatments on the mRNA expression of TANK, RIPK1, NFKB1, TNFRSF10D, and TRAF2. Among the cell lines, SKOV-3 ovarian adenocarcinoma cells demonstrated the highest resistance to cisplatin treatment (0.125 mg/mL), followed by TOV-21G (0.076 mg/mL) and OV-90 cells (0.028 mg/mL). Regarding paclitaxel treatment, the SKOV-3 cell line exhibited the highest resistance (1.4 µg/mL), followed by OV-90 (1.3 µg/mL) and TOV-21G cells (0.9 µg/mL). Gene expression analysis after paclitaxel treatment remained unchanged; however, after cisplatin treatment, TNFRSF10D was observed to be upregulated nearly 100-fold in SKOV-3 compared to all other cell lines studied. SKOV-3 is described as cisplatin and tumor necrosis factor-resistant. Despite the defective signaling of the TNFRSF10D receptor for apoptosis, it can activate the NFKB transcription factor through non-canonical TRAIL signaling, contributing to a pro-inflammatory immune response. In light of this, damage associated with cisplatin increases TNFRSF10D expression and may promote cell survival through non-canonical NFKB pathway activation. This suggests that resistance to TRAIL-induced apoptosis in these cells could serve as a promising chemoresistance biomarker in OC.

RESUMO

OBJECTIVE: Intraoperative complications of hysteroscopy, such as the creation of a false passage, cervix dilatation failure, and uterine perforation, may require suspension of the procedure. Some patients refuse a new procedure, which delays the diagnosis of a possible serious uterine pathology. For this reason, it is essential to develop strategies to increase the success rate of hysteroscopy. Some authors suggest preoperative use of topical estrogen for postmenopausal patients. This strategy is common in clinical practice, but studies demonstrating its effectiveness are scarce. The aim of this study was to evaluate the effect of cervical preparation with promestriene on the incidence of complications in postmenopausal women undergoing surgical hysteroscopy. METHODS: This is a double-blind clinical trial involving 37 postmenopausal patients undergoing surgical hysteroscopy. Participants used promestriene or placebo vaginally daily for 2 weeks and then twice a week for another 2 weeks until surgery. RESULTS: There were 2 out of 14 (14.3%) participants with complications in the promestriene group and 4 out of 23 (17.4%) participants in the placebo group (p=0.593). The complications were difficult cervical dilation, cervical laceration, and vaginal laceration. CONCLUSION: Cervical preparation with promestriene did not reduce intraoperative complications in postmenopausal patients undergoing surgical hysteroscopy.

RESUMO

Synopsis: This is a systematic review and meta-analysis comparing surgical excision with percutaneous ultrasound-guided vacuum-assisted excision (US-VAE) for the treatment of benign phyllodes tumor (PT) using local recurrence (LR) as the endpoint. Objective: To determine the frequency of local recurrence (LR) of benign phyllodes tumor (PT) after ultrasound-guided vacuum-assisted excision (US-VAE) compared to the frequency of LR after surgical excision. Method: A systematic review and meta-analysis [following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) standard] was conducted by comparing LR in women older than 18 years treated for benign PT by US-VAE compared with local surgical excision with at least 12 months of follow-up. Studies were retrieved from PubMed, Scopus, Web of Science, and Embase. The pooled effect measure used was the odds ratio (OR) of recurrence. Results: Five comparative prospective or retrospective observational studies published between January 1, 1992, and January 10, 2022, comparing surgical excision with percutaneous US-VAE for LR of benign PT met the selection criteria. Four were retrospective observational cohorts, and one was a prospective observational cohort. A total of 778 women were followed up. Of them, 439 (56.4%) underwent local surgical excision, and 339 (43.6%) patients had US-VAE. The median age of patients in the five studies ranged from 33.7 to 39 years; the median size ranged from 1.5 cm to 3.0 cm, and the median follow-up ranged from 12 months to 46.6 months. The needle gauge ranged from 7G to 11G. LR rates were not statically significant between US-VAE and surgical excision (41 of 339 versus 34 of 439; OR 1.3; p = 0.29). Conclusion: This meta-analysis suggests that using US-VAE for the removal of benign PT does not increase local regional recurrence and is a safe minimally invasive therapeutic option.

RESUMO

PURPOSE: To investigate the tensile biomechanical properties of round and uterosacral ligaments. METHODS: Tissue samples were obtained from 15 female cadavers without pelvic organ prolapse. Uniaxial tensile tests were performed to obtain stiffness and maximum stress of round and uterosacral ligaments. Correlations were calculated using the Pearson correlation coefficient. Statistical differences between groups were tested using Student's paired and unpaired t test. RESULTS: There was a great variability in the measurements of stiffness and maximum stress in pelvic ligaments. The round ligaments demonstrated stiffness of 9.1 ± 1.6 MPa (mean ± SEM) (ranging from 2 to 25.6 MPa) and maximum stress of 4.3 ± 0.7 MPa (ranging from 1.2 to 11.5 MPa). The stiffness of the uterosacral ligaments was 14.1 ± 1.4 MPa (ranging from 5.7 to 26.1 MPa) with maximum stress of 6.3 ± 0.8 MPa (ranging from 2.2 to 11.9 MPa). There was a strong positive correlation between stiffness and maximum stress in female pelvic ligaments (ρ = 0.851; p < 0.001). The uterosacral ligaments demonstrated higher stiffness and maximum stress compared to the round ligaments (p = 0.006 and p = 0.034; respectively). Age, body mass index and menopausal status were not associated with the biomechanical proprieties of round and uterosacral ligaments. Nulliparous women had lower uterosacral stiffness (15.5 ± 1.3 vs. 10 ± 1.8 MPa; p = 0.033) and maximum stress (8.2 ± 0.9 vs. 4.2 ± 1.1 MPa; p = 0.028) compared to parous women. CONCLUSION: The uterosacral ligaments are significantly more resistant than round ligaments. Parturition seems to enhance the stiffness and maximum stress of the ligaments.

RESUMO

INTRODUCTION: The Internet and electronic devices with Internet access allow for a greater fluidity of information and speed of communication, especially in the field of health. Abnormal uterine bleeding (AUB) affects approximately 3-30% of women and can negatively impact their health and quality of life. Information regarding AUB that is available on the Internet may not be clear or accurate, rendering it difficult to understand and likely to result in delayed medical evaluation, which subsequently leads to worsening of the AUB. OBJECTIVE: To evaluate the quality of the information regarding AUB currently available on the Internet, including information regarding treatments. METHODS: The Google Trends website was searched for the most widely used English terms related to AUB. The identified descriptors were searched individually on the Google, Yahoo!, and Bing search engines. The first 10 results of each search were pre-selected and evaluated for inclusion in this study. Selected websites were categorically divided into two groups (news/magazine and academic) and individually analyzed by three experts using the DISCERN quality criteria (reliability, general quality, and quality of information) and the presence or absence of the Health on the Net Foundation Code of Conduct (HONcode®) seal. RESULTS: Of the 168 websites included in this study, 60.1% were allocated to the news/magazine group and 39.9% were allocated to the academic group. Over half of the websites (54.2%) did not have the HONcode® quality seal. Websites in the academic group were more likely to include accurate information regarding AUB with greater reliability than websites in the news/magazine group. There were no statistical differences regarding the general quality of the websites. Most websites were rated as either moderate quality (70.8%) or low quality (28.6%). The HONcode® criterion was found to be a confounding factor of the analyses, as the grouping and quality results of websites without this seal were significantly associated. In addition, websites in the news/magazines group were 6.7 times more likely to provide low quality information than websites in the academic group (odds ratio: 6.7; 95% confidence interval: 2.1-21.4). CONCLUSION: The information regarding AUB that is available on the Internet is of low to moderate quality. Academic websites present more reliable information of greater quality. The presence of the HONcode® seal is considered important to determine the quality of the content of a website, especially for news/magazine websites, and may help Internet users identify websites that contain more reliable information. Algorithms and applications that categorize the quality of information and the reliability of health content may be useful tools that can help patients clarify their symptoms for several conditions including AUB.

RESUMO

Purpose: This study, conducted during the COVID-19 crisis, primarily aimed to compare the acute toxicity between conventional fractionated radiation therapy (CF-RT) with hypofractionated radiation therapy (HF-RT) among patients who underwent breast-conserving surgery or mastectomy in whom breast or chest wall and regional nodal irradiation (RNI) were indicated. The secondary endpoints were both acute and subacute toxicity, cosmesis, quality of life, and lymphedema features. Methods: In this open and non-inferiority randomized trial, patients (n = 86) were randomly allocated 2:1 in the CF-RT arm (n = 33; 50 Gy/25 fractions ± sequential boost [10 Gy/5 fractions]) versus the HF-RT arm (n = 53; 40 Gy/15 fractions ± concomitant boost [8 Gy/15 fractions]). Toxic effects and cosmesis evaluation used the Common Terminology Criteria for Adverse Events, version 4.03 (CTCAE) and the Harvard/National Surgical Adjuvant Breast and Bowel Project (NSABP)/Radiation Therapy Oncology Group (RTOG) scale. For the patient-reported quality of life (QoL), the European Organisation for Research and Treatment of Cancer quality of life questionnaire (EORTC QLQ-C30) and the breast cancer-specific supplementary questionnaire (QLQ-BR23) were used. Lymphedema was assessed by comparing volume differences between the affected and contralateral arms using the Casley-Smith formula. Results: Grade 2 and grade 3 dermatitis were lower with HF-RT than with CF-RT (28% vs. 52%, and 0% vs. 6%, respectively; p = 0.022). HF-RT had a lower rate of grade 2 hyperpigmentation (23% vs. 55%; p = 0.005), compared to CF-RT. No other differences in overall rates of physician-assessed grade 2 or higher and grade 3 or higher acute toxicity between HF-RT and CF-RT were registered. There was no statistical difference between groups regarding cosmesis, lymphedema rate (13% vs. 12% HF-RT vs. CF-RT; p = 1.000), and functional and symptom scales, during both the irradiation period and after 6 months of the end of treatment. The results revealed that the subset of patients up to 65 years or older did not show a statistical difference between both arm fractionation schedules (p > 0.05) regarding skin rash, fibrosis, and lymphedema. Conclusion: HF-RT was non-inferior to CF-RT, and moderate hypofractionation showed lower rates of acute toxicity, with no changes in quality-of-life outcomes. Clinical trial registration: ClinicalTrials.gov, identifier NCT40155531.
