RESUMO
PURPOSE: Consistency of nomenclature within radiation oncology is increasingly important as big data efforts and data sharing become more feasible. Automation of radiation oncology workflows depends on standardized contour nomenclature that enables toxicity and outcomes research, while also reducing medical errors and facilitating quality improvement activities. Recommendations for standardized nomenclature have been published in the American Association of Physicists in Medicine (AAPM) report from Task Group 263 (TG-263). Transitioning to TG-263 requires creation and management of structure template libraries and retraining of staff, which can be a considerable burden on clinical resources. Our aim is to develop a program that allows users to create TG-263-compliant structure templates in English, Spanish, or French to facilitate data sharing. METHODS AND MATERIALS: Fifty-three premade structure templates were arranged by treated organ based on an American Society for Radiation Oncology (ASTRO) consensus paper. Templates were further customized with common target structures, relevant organs at risk (OARs) (eg, spleen for anatomically relevant sites such as the gastroesophageal junction or stomach), subsite- specific templates (eg, partial breast, whole breast, intact prostate, postoperative prostate, etc) and brachytherapy templates. An informal consensus on OAR and target coloration was also achieved, although color selections are fully customizable within the program. RESULTS: The resulting program is usable on any Windows system and generates template files in practice-specific Digital Imaging and Communications In Medicine (DICOM) or XML formats, extracting standardized structure nomenclature from an online database maintained by members of the TG-263U1, which ensures continuous access to up-to-date templates. CONCLUSIONS: We have developed a tool to easily create and name DICOM radiation therapy (DICOM-RT) structures sets that are TG-263-compliant for all planning systems using the DICOM standard. The program and source code are publicly available via GitHub to encourage feedback from community users for improvement and guide further development.

BACKGROUND: In a recent phase III randomized control trial, delivering a focal radiotherapy (RT) boost to tumors visible on MRI was shown to improve disease-free survival and regional/distant metastasis-free survival for patients with prostate cancer-without increasing toxicity. The aim of this study was to assess how widely this technique is being applied in current practice, as well as physicians' perceived barriers toward its implementation. METHODS: We invited radiation oncologists to complete an online questionnaire assessing their use of intraprostatic focal boost in December 2022 and February 2023. To include perspectives from a broad range of practice settings, the invitation was distributed to radiation oncologists worldwide via email list, group text platform, and social media. RESULTS: 263 radiation oncologist participants responded. The highest-represented countries were the United States (42%), Mexico (13%), and the United Kingdom (8%). The majority of participants worked at an academic medical center (52%) and considered their practice to be at least partially genitourinary (GU)-subspecialized (74%). Overall, 43% of participants reported routinely using intraprostatic focal boost. Complete GU-subspecialists were more likely to implement focal boost, with 61% reporting routine use. In both high-income and low-to-middle-income countries, less than half of participants routinely use focal boost. The most cited barriers were concerns about registration accuracy between MRI and CT (37%), concerns about risk of additional toxicity (35%), and challenges to accessing high-quality MRI (29%). CONCLUSIONS: Two years following publication of a randomized trial of patient benefit without increased toxicity, almost half of the radiation oncologists surveyed are now routinely offering focal RT boost. Further adoption of this technique might be aided by increased access to high-quality MRI, better registration algorithms of MRI to CT simulation images, physician education on benefit-to-harm ratio, and training on contouring prostate lesions on MRI.

Background: In a recent phase III randomized control trial (FLAME), delivering a focal radiotherapy (RT) boost to tumors visible on MRI was shown to improve outcomes for prostate cancer patients without increasing toxicity. The aim of this study was to assess how widely this technique is being applied in current practice as well as physicians' perceived barriers toward its implementation. Methods: An online survey assessing the use of intraprostatic focal boost was conducted in December 2022 and February 2023. The survey link was distributed to radiation oncologists worldwide via email list, group text platform, and social media. Results: The survey initially collected 205 responses from various countries over a two-week period in December 2022. The survey was then reopened for one week in February 2023 to allow for more participation, leading to a total of 263 responses. The highest-represented countries were the United States (42%), Mexico (13%), and the United Kingdom (8%). The majority of participants worked at an academic medical center (52%) and considered their practice to be at least partially genitourinary (GU)-subspecialized (74%). 57% of participants reported not routinely using intraprostatic focal boost. Even among complete subspecialists, a substantial proportion (39%) do not routinely use focal boost. Less than half of participants in both high-income and low-to-middle-income countries were shown to routinely use focal boost. The most commonly cited barriers were concerns about registration accuracy between MRI and CT (37%), concerns about risk of additional toxicity (35%), and challenges to accessing high-quality MRI (29%). Conclusion: Despite level 1 evidence from the FLAME trial, most radiation oncologists surveyed are not routinely offering focal RT boost. Adoption of this technique might be accelerated by increased access to high-quality MRI, better registration algorithms of MRI to CT simulation images, physician education on benefit-to-harm ratio, and training on contouring prostate lesions on MRI.
RESUMO
Purpose: For radiation oncology, social media is a favored communication platform, but it uses non-structured hashtags, which limits communication. In this work, we created a set of structured hashtags with key opinion leaders in radiation oncology, and we report on their use after two years post-deployment. Materials/Methods: Hashtags were created, voted on, and refined by crowdsourcing 38 international experts, including physicians, physicists, patients, and organizations from North America, Europe, and Australia. The finalized hashtag set was shared with the radiation oncology community in September 2019. The number of tweets for each hashtag was quantified via Symplur through December 2021. For the top five tweeted hashtags, we captured the number of yearly tweets in the pre-deployment and post-deployment periods from 09/01/2019 to 08/31/2021. Results: The initial 2019 list contained 39 hashtags organized into nine categories. The top five hashtags by total number of tweets were: #Radonc, #PallOnc, #MedPhys, #SurvOnc, and #SuppOnc. Six hashtags had less than 10 total tweets and were eliminated. Post-deployment, there was an increase in the yearly tweets, with the following number of tweets by the second year post-deployment: #RadOnc (98,189 tweets), #MedPhys (15,858 tweets), and #SurvOnc (6,361 tweets). Two popular radiation oncology-related hashtags were added because of increased use: #DEIinRO (1,603 tweets by year 2) and #WomenWhoCurie (7,212 tweets by year 2). Over the two years, hashtags were used mostly by physicians (131,625 tweets, 34.8%). Conclusion: We created and tracked structured social media hashtags in radiation oncology. These hashtags disseminate information among a diverse oncologic community. To maintain relevance, regular updates are needed.
RESUMO
PURPOSE: Workforce shortages will impact oncologists' ability to provide both active and survivorship care. While primary care provider (PCP) or survivorship clinic transition has been emphasized, there is little evidence regarding patient comfort. METHODS: We developed an online survey in partnership with patient advocates to assess survivors' comfort with PCP or survivorship clinic care and distributed the survey to online, cancer-specific patient communities from June to August 2020. Descriptive and logistic regression analyses were conducted. RESULTS: A total of 975 surveys were complete. Most respondents were women (91%) and had private insurance (65%). Thirty-six cancer types were reported. Ninety-three percent had a PCP. Twenty-four percent were comfortable seeing a PCP for survivorship care. Higher odds of comfort were seen among respondents who were Black or had stage 0 cancer; female sex was associated with lower odds. Fifty-five percent were comfortable with a survivorship clinic. Higher odds of comfort were seen with lymphoma or ovarian cancer, > 15 years from diagnosis, and non-US government insurance. Lower odds were seen with melanoma, advanced stage, Medicaid insurance, and one late effect. Preference for PCP care was 87% for general health, 32% for recurrence monitoring, and 37% for late effect management. CONCLUSIONS: One quarter of cancer survivors were comfortable with PCP-led survivorship care and about half with a survivorship clinic. Most preferred oncologist care for recurrence monitoring and late-effect management. IMPLICATIONS FOR CANCER SURVIVORS: Patient preference and comfort should be considered when developing survivorship care models. Future efforts should focus on facilitating patient-centered transitions to non-oncologist care.

Purpose: Our purpose was to determine the utilization of and barriers to implementation of radiopharmaceutical therapy (RPT) among U.S. radiation oncologists. Methods and Materials: An anonymous, voluntary 21-item survey directed toward attending radiation oncologists was distributed via social media platforms (Twitter, LinkedIn, Facebook, Student Doctor Network). Questions assessed practice characteristics, specific RPT prescribing patterns, RPT prescribing interest, and perceived barriers to RPT implementation. Nonparametric χ2 test was used for correlation statistics. Results: Of the 142 respondents, 131 (92.3%) practiced in the United States and were included for this analysis. Respondents were well balanced in terms of practicing region, population size served, practice setting, and years in practice. Forty-eight percent (n = 63) reported prescribing at least 1 RPT. An additional 7% (n = 8) participate in RPT administration without billing themselves. Among those that actively prescribed RPT, the mean cumulative cases per month was 4.2 (range, 1-5). The most commonly prescribed radionuclides were radium-223 (40%; mean 2.8 cases/mo), iodine-131 (18%; mean 2.3 cases/mo), yttrium-90 (13%; mean 3.4 cases/mo), "other" (8%), samarium-153 (6%; mean 1.0 cases/mo), and strontrium-89 and phosphorous-32 (2% each; mean 1.8 and 0.4 cases/mo, respectively). Of those who answered "other," lutetium-177 dotatate was most commonly prescribed (8%). No significant (P < .05) association was noted between practice type, practice location, years of practice, or practice volume with utilization of any RPTs. Most radiation oncologists (56%, n = 74) responded they would like to actively prescribe more RPT, although 27% (n = 35) were indifferent, and 17% (n = 22) said they would not like to prescribe more RPT. Perceived barriers to implementation were varied but broadly categorized into treatment infrastructure (44%, n = 57), interspecialty relations (41%, n = 53), lack of training (23%, n = 30), and financial considerations (16%, n = 21). Conclusions: Among surveyed U.S. radiation oncologists, a significant number reported prescribing at least 1 RPT. The majority expressed interest in prescribing additional RPT. Wide-ranging barriers to implementation exist, most commonly interspecialty relations, treatment infrastructure, lack of training, and financial considerations.
RESUMO
Despite their increased enrollment into medical school, women still face systemic barriers in medicine, whether in an academic or nonacademic setting. Those from Under-Represented Minority (URM) groups face similar issues, which may affect their desire to enter, pursue, and/or maintain a career in medicine. Social media provides unique opportunities for peer-to-peer support among members of URM communities and for amplification of their voices calling for social justice-here defined as a redistribution of power and the quest for equity in access to opportunities, including access to mentorship, professional development, and timely promotion in academic rank. These issues are relevant to oncologists especially as we strive for diversity, equity, and inclusion and to ensure that our patients have equal access to care, regardless of their circumstances. In this article, we review current literature that highlights issues faced by women and historically URM groups in medicine, particularly in oncology. We also discuss the physician's role as a social justice advocate and the concept of the public physician.

The value of low-dose whole thoracic radiation therapy (LD-WTRT) for SARS-CoV-2 (COVID-19) pneumonia is unknown. Should ongoing clinical trials demonstrate that LD-WTRT proves effective for COVID-19 pneumonia recovery, widespread rapid implementation will be helpful globally. Our aim was to outline a pragmatic process for safe and efficient administration of LD-WTRT to patients with COVID-19 pneumonia that could be implemented successfully in a community hospital setting based on participation in the PreVent clinical trial of LD-WTRT.

INTRODUCTION: Social media connects people globally and may enhance access to radiation oncology information. We characterized the global growth of the radiation oncology Twitter community using the hashtag #radonc. MATERIALS AND METHODS: We analyzed all public tweets bearing the hashtag #radonc from 2014 to 2019 using Symplur Signals. We collected data on #radonc activity and growth, stakeholder distribution, user geolocation, and languages. We obtained global Twitter user data and calculated average annual growth rates for users and tweets. We analyzed growth rates by stakeholder. We conducted thematic analysis on a sample of tweets in each three-year period using frequently occurring two-word combinations. RESULTS: We identified 193,115 tweets including #radonc composed by 16,645 Twitter users. Globally, users wrote in 35 languages and came from 122 countries, with the known highest users from the United States, United Kingdom, and Spain. Use of #radonc expanded from 23 countries in 2014 to 116 in 2019. The average annual growth rate in #radonc users and tweets was 70.5% and 69.2%, respectively. The annual growth rate of #radonc users was significantly higher than for all Twitter users (p = 0.004). While doctors were the source of 46.9% of all tweets, research and government organizations had annual increases in tweet volume of 84.6% and 211.4%, respectively. From 2014 to 2016, promotion of the radiation oncology community was the most active theme, though this dropped to 7th in 2017-2019 as discussion increased regarding aspects of radiation and treated disease sites. CONCLUSION: Use of #radonc has grown rapidly into a global community. Focused discussion related to radiation oncology has outpaced the growth of general Twitter use, both among physicians and non-physicians. #radonc has grown into a self-sustaining community. Further research is necessary to define the risks and benefits of social media in medicine and to determine whether it adds value to oncology practice.
RESUMO
Providing high-quality radiation therapy in medically underserved, low-resource environments can be challenging in the United States. During the American Society of Radiation Oncology 2020 Annual Meeting, the American Society for Radiation Oncology Committee on Health Equity, Diversity, and Inclusion hosted 4 radiation oncologists from both academic and community practices in an educational session. Speakers discussed creative ways to overcome barriers to equitable cancer care and outcomes for their vulnerable patient populations in both rural and urban settings. Successful tactics have included applying for state-sponsored grants, lobbying hospital leadership for equipment upgrades, implementing quality improvement programs specifically targeting the needs of the patient population, studying novel hypofractionation schedules, monitoring toxicities using wearable devices, and expanding transportation options.
RESUMO
BACKGROUND: Management of prostate cancer after surgery is controversial. Past studies on adjuvant radiotherapy (aRT) for higher-risk features have had conflicting results. Through the collaborative conversations of the global radiation oncology Twitter-based journal club (#RadOnc #JC), we explored this complex topic to share recent advances, better understand what the global radiation oncology community felt was important and inspire next steps. METHODS: We selected the recent publication of a landmark international randomized controlled trial (RCT) comparing immediate and salvage radiotherapy for prostate cancer, RADICALS-RT, for discussion over the weekend of January 16 to 17, 2021. Coordination included open access to the article and an asynchronous portion to decrease barriers to participation, cooperation of study authors (CP, MS) who participated to share deeper insights including a live hour, and curation of related resources and tweet content through a blog post and Wakelet journal club summary. DISCUSSION OF RESULTS: Our conversations created 2,370,104 impressions over 599 tweets with 51 participants spanning 11 countries and 5 continents. A quarter of the participants were from the US (13/51) followed by 10% from the UK (5/51). Clinical or Radiation Oncologists comprised 59% of active participants (16/27) with 62% (18/29) reporting giving aRT within the last 5 years. Discussion was interdisciplinary with three urologists (11%), three trainees (11%), and two physiotherapists (7%). Four months after the journal club its article Altmetric score had increased by 7% (214 to 229). Thematic analysis of tweet content suggested participants wanted clarification on definitions of adjuvant (aRT) and salvage radiotherapy (sRT) including indications, timing, and decision-making tools including guidelines; more interdisciplinary and cross-sectoral collaboration including with patients for study design including survivorship and meaningful outcomes; more effective knowledge translation including faster clinical trials; and more data including mature results of current trials, particular high-risk features (Gleason Group 4+, pT4b+, and margin-positive disease), implications of newer technologies such as PSMA-PET and genomic classifiers, and better explanations for practice pattern variations including underutilization of radiotherapy. This was further explored in the context of relevant literature. CONCLUSION: Together, this global collaborative review on the postoperative management of prostate cancer suggested a stronger signal for the uptake of early salvage radiation treatment with careful PSA monitoring, more sensitive PSA triggers, and expected access to radiotherapy. Questions still remain on potential exceptions and barriers to use. These require better decision-making tools for all practice settings, consideration of newer technologies, more pragmatic trials, and better use of social media for knowledge translation.
RESUMO
BACKGROUND: Genetic testing, particularly for BRCA1/2, is increasingly important in prostate cancer (PCa) care, with impact on PCa management and hereditary cancer risk. However, the extent of public awareness and online discourse on social media is unknown, and presents opportunities to identify gaps and enhance population awareness and uptake of advances in PCa precision medicine. OBJECTIVE: The objective of this study was to characterize activity and engagement across multiple social media platforms (Twitter, Facebook, and YouTube) regarding BRCA and genetic testing for PCa compared with breast cancer, which has a long history of public awareness, advocacy, and prominent social media presence. METHODS: The Symplur Signals online analytics platform was used to obtain metrics for tweets about (1) #BRCA and #breastcancer, (2) #BRCA and #prostatecancer, (3) #genetictesting and #breastcancer, and (4) #genetictesting and #prostatecancer from 2016 to 2020. We examined the total number of tweets, users, and reach for each hashtag, and performed content analysis for a subset of tweets. Facebook and YouTube were queried using analogous search terms, and engagement metrics were calculated. RESULTS: During a 5-year period, there were 10,005 tweets for #BRCA and #breastcancer, versus 1008 tweets about #BRCA and #prostatecancer. There were also more tweets about #genetictesting and #breastcancer (n=1748), compared with #genetic testing and #prostatecancer (n=328). Tweets about genetic testing (12,921,954) and BRCA (75,724,795) in breast cancer also had substantially greater reach than those about PCa (1,463,777 and 4,849,905, respectively). Facebook groups and pages regarding PCa and BRCA/genetic testing had fewer average members, new members, and new posts, as well as fewer likes and followers, compared with breast cancer. Facebook videos had more engagement than YouTube videos across both PCa and breast cancer content. CONCLUSIONS: There is substantially less social media engagement about BRCA and genetic testing in PCa compared with breast cancer. This landscape analysis provides insights into strategies for leveraging social media platforms to increase public awareness about PCa germline testing, including use of Facebook to share video content and Twitter for discussions with health professionals.
RESUMO
The role of radiation therapy in metastatic cancer is rapidly evolving with increased understanding of the oligometastatic state and improved technologies to deliver higher doses of radiation with greater precision and avoidance of normal tissues than before. Recent data have demonstrated that the use of stereotactic ablative radiotherapy (SABR) in oligometastatic disease confers a survival benefit. Yet, the current enthusiasm must be balanced with caution. Here we summarize the evidence in favor of SABR for oligometastatic patients as well as the concerns regarding rapid adoption into clinical practice and outline broad principles to guide clinical trials evaluating the role of SABR in oligometastatic disease. As oncologists, we must exercise due diligence and gather the appropriate evidence necessary to 1) understand the oligometastatic disease state and 2) optimize benefit in those patients before broadly offering SABR to all. Any alternative path forward will do our field and our patients a great injustice.

PURPOSE: Resident physicians use social media (SM) for many reasons. We sought to characterize current SM use by radiation oncology (RO) trainees for education and professional development. METHODS AND MATERIALS: An anonymous 40-question survey was sent by e-mail to RO residents in the 2018 to 2019 academic year. SM platform use, time spent on SM, professional use, and opinions regarding SM use were assessed. Descriptive statistics and a univariate logistic regression analysis were performed to identify factors associated with perceptions of SM and spending >25% of SM time for academic or professional purposes. RESULTS: Of the 615 residents surveyed, 149 responded (24% response rate). Facebook (73%), theMednet (62%), Instagram (59%), Twitter (57%), and Doximity (50%) were the top SM platforms used. Most respondents (53%) reported <25% of overall SM time on professional/academic purposes, and 21% reported using SM >60 minutes per day over the past week. Residents with an RO mentor on SM (n = 35; 24%; odds ratio [OR]: 2.79; 95% confidence interval [CI], 1.29-6.08; P = .010), those participating in RO discussions on SM (n = 71; 48%; OR: 2.85; 95% CI, 1.42-5.72; P = .003), and those interacting with professional societies (n = 69; 46%; OR: 7.11; 95% CI, 3.32-15.24; P < .001) were more likely to spend >25% of their SM time on professional/academic purposes. The vast majority of respondents agreed that SM exposed them to novel educational content (82%) and was helpful for career development (65%). In addition, 69% agreed that SM can improve clinical skills and knowledge. A substantial minority agreed that SM distracts them from studying (38%) or they felt pressure to have a SM presence (29%). CONCLUSIONS: Most RO residents reported that SM provides novel educational content and can help with career development. Potential disadvantages of SM for trainees may include distraction and pressure to maintain a SM presence. SM use by RO trainees merits further research to optimize its potential for education and professional development.
RESUMO
BACKGROUND/PURPOSE: We describe a case of full-thickness macular hole formation in a patient with exudative age-related macular degeneration after an intravitreal ranibizumab injection and its surgical management. METHODS: This case is a retrospective, interventional case report. RESULTS: A 77-year-old woman with bilateral exudative age-related macular degeneration and pre-existing retinal pigment epithelium tear developed a full-thickness macular hole after intravitreal ranibizumab. The macular hole was repaired successfully with pars plana vitrectomy, internal limiting membrane peel, and 16% C3F8 gas fill. CONCLUSION: To the best of our knowledge, this is the first reported case of full-thickness macular hole after a retinal pigment epithelium tear repaired successfully with vitrectomy, resulting in improved visual acuity.

The growing number of cancer survivors and the high prevalence of cancer-related physical and psychosocial effects pose important and pressing challenges to health systems. The coronavirus disease 2019 (COVID-19) pandemic has led to further stressors on cancer survivors and health care systems. As the pandemic continues to have substantial impact on the world, it is critical to focus attention on the health care needs of cancer survivors. In this commentary, we propose an adoption of essential steps that should be part of a continuous adaptive approach to promote effective cancer survivorship care during ongoing COVID-19 waves and beyond.
