Development and dissemination of structured hashtags for radiation oncology: Two-Year trends.

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.

#ThisIsBrachytherapy: Increasing awareness of brachytherapy.

PURPOSE: The use of brachytherapy continues to be a vital application of radiation oncology for various cancers. Despite this, there has been a decrease in the utilization of brachytherapy in many cancers. Social media in medicine facilitates engagement and advocacy. We launched a social media campaign to bring awareness of brachytherapy throughout the world with #ThisIsBrachytherapy hashtag on July 17, 2019. METHODS AND MATERIALS: #ThisIsBrachytherapy hashtag was registered with Symplur Healthcare Hashtag Project. We collected total tweet counts, retweet counts, impression counts, geolocation, top 10 influencers, associated hashtags, associated words, and word sentiment score. RESULTS: The campaign launched on July 17, 2019, had a total of 145 tweets on that day with 213,416 impressions. Twenty-seven accounts (45%) were identified as physicians. Top countries which tweeted, among those with information available, included the United States, United Kingdom, and Australia. Since July 17, 2019, there has been an increase in tweets using #ThisIsBrachytherapy, with 1990 total tweets with 1,999,248 impressions. Fifty-four percent (1030) of the tweets contained photos and 319 contained links. This was from 462 unique users. Word sentiment was overwhelmingly positive. Associated hashtags with #ThisIsBrachytherapy included most commonly #radonc, #brachytherapy, #brachy, #prostatecancer, and #pcsm. CONCLUSIONS: The #ThisIsBrachytherapy inaugural campaign was successful and has continued to grow throughout the months after the initiation. By continuing to advocate for brachytherapy through the social media campaign #ThisIsBrachytherapy, we can empower radiation oncologists, especially trainees, and patients to address underutilization.

Predictors of Extracapsular Extension in Patients With Squamous Cell Carcinoma of the Head and Neck and Outcome Analysis.

Introduction Extracapsular extension (ECE) in the lymph nodes for patients with head and neck cancer has been found to be a poor prognostic factor in multiple studies. The purpose of the study is to evaluate the predictive factors for ECE on computer tomography (CT) imaging for patients undergoing surgery and to analyze outcomes. Methods We conducted an Institutional Review Board-approved, Health Insurance Portability and Accountability Act (HIPAA)-compliant retrospective review of 82 patients with biopsy-proven squamous cell carcinomas of the head and neck who underwent definitive surgery without neoadjuvant chemotherapy or radiation therapy. CT scans were evaluated for the level of involvement, size, and presence or absence of central necrosis. Extracapsular extension in lymph nodes on the postoperative pathology was correlated with the central necrosis in the lymph nodes appreciated on the CT neck with contrast. Survival estimates were evaluated using the Kaplan-Meier test. Results ECE on postoperative pathology was seen in 74.07% of patients who had evidence of central necrosis in lymph nodes on preoperative CT neck compared to 46.43% without CT necrosis (p=0.013). The incidence of ECE is higher in poorly differentiated tumors and also nodal stages >N2c at presentation. Patents with ECE had inferior disease-free and overall survival (OS). Conclusions Our results reveal that patients with necrosis on CT and with moderately to poorly differentiated tumors have a high incidence of extracapsular extension. There was no difference in local control (LC) between the groups of patients, but the OS was inferior in patients with ECE. Predicting extracapsular extension upfront helps to formulate the appropriate treatment. We propose to study additional chemotherapy to improve outcomes in patients with positive extracapsular extension.

Management of Advanced-stage Hypopharyngeal Carcinoma: 25-Year Experience from a Tertiary Care Medical Center.

Introduction Due to conflicting data in the literature, there is a continuing debate on whether advanced hypopharyngeal carcinoma patients should be treated with definitive surgery or chemoradiotherapy. The purpose of this study is to evaluate the management and outcomes of advanced hypopharyngeal carcinoma in a tertiary care institution over the last 25 years. Methods An Institutional Review Board (IRB)-approved and HIPPA-compliant retrospective analysis was performed of patients with advanced-stage squamous cell carcinoma of the hypopharynx treated at our institution between January 1994 and December 2018. Data regarding demographics, stage, treatment, and follow-up were collected. Outcomes including median survival and overall survival were calculated using the Kaplan Meier method. All analyses were performed using SPSS v. 24.  Results This study included a total of 103 advanced stage hypopharyngeal cancer patients. The median age for this cohort is 61 years (range: 41-88, SD 9.3). Of the total 103 eligible patients treated, 92 (89.3%) were male and 11 (10.7%) female; 61 (59.2%) were African Americans, 39 (37.9%) were Caucasians and three (2.9%) were other races. Seventeen patients (16.5%) had stage III disease, whereas 86 (83.5%) patients were diagnosed with Stage IV A or B disease. Seventy-two patients (69.9%) were treated with definitive chemoradiotherapy (ChemoRT group), and 31 patients (30.1%) underwent primary surgery with or without adjuvant treatments (Surgery group). The two treatment groups were similar in terms of age, gender, ethnicity, alcohol status, N staging, and subsites but were significantly different for smoking status (p = 0.035) and T staging (p = 0.024). The median follow-up was 17 months. The median survival of the overall cohort was 26 months, and five-year overall survival was 25.5%. The median survival was found to be significantly better for the surgery group as compared to the definitive chemoradiotherapy group (43 months vs 16 months, p = 0.049). The five-year overall survival (OS; 41.5% vs 18.5%, p = 0.049) and disease-free survival (DFS; 75.3% vs 56%; p = 0.029) were significantly better for patients in the surgery group compared to the chemoradiotherapy group. On multivariate Cox-regression analysis, lymph nodal status (HR = 1.27, CI: 1.00-1.62, p = 0.047) and chemoradiation treatment (HR = 1.82, CI: 1.00-3.29, p = 0.048) were associated with higher risk of mortality.  Conclusion In our single institutional experience of advanced hypopharyngeal carcinoma management, the five-year overall survival rate was found to be 25.5 % and was the poorest among head and neck cancers. The patients with advanced hypopharyngeal cancer treated with surgery followed by adjuvant radiation or chemoradiation have significantly improved overall survival compared to those treated with definitive chemoradiotherapy. Further research warranted for early detection and better treatment to improve the cure rate in hypopharyngeal carcinoma patients.

Lack of Racial Survival Differences in Metastatic Prostate Cancer in National Cancer Data Base (NCDB): A Different Finding Compared to Non-metastatic Disease.

Background: Inconsistent findings have been reported in the literature regarding racial differences in survival outcomes between African American and white patients with metastatic prostate cancer (mPCa). The current study utilized a national database to determine whether racial differences exist among the target population to address this inconsistency. Methods: This study retrospectively reviewed prostate cancer (PCa) patient data (N = 1,319,225) from the National Cancer Database (NCDB). The data were divided into three groupings based on the metastatic status: (1) no metastasis (N = 318,291), (2) bone metastasis (N = 29,639), and (3) metastases to locations other than bone, such as brain, liver, or lung (N = 952). Survival probabilities of African American and white PCa patients with bone metastasis were examined through parametric proportional hazards Weibull models and Bayesian survival analysis. These results were compared to patients with no metastasis or other types of metastases. Results: No statistically supported racial disparities were observed for African American and white men with bone metastasis (p = 0.885). Similarly, there were no racial disparities in survival for those men suffering from other metastases (liver, lung, or brain). However, racial disparities in survival were observed among the two racial groups with non-metastatic PCa (p < 0.001) or when metastasis status was not taken into account (p < 0.001). The Bayesian analysis corroborates the finding. Conclusion: This research supports our previous findings and shows that there are no racial differences in survival outcomes between African American and white patients with mPCa. In contrast, racial disparities in the survival outcome continue to exist among non-metastatic PCa patients. Further research is warranted to explain this difference.

Cross-Sectional Gender Analysis of US Radiation Oncology Residency Programs in 2019: More Than a Pipeline Issue?

PURPOSE: The purpose of this study is to assess the current status of gender disparities in academic radiation oncology departments in the United States and the associated factors. METHODS AND MATERIALS: The data were collected from publicly available resources, including websites of individual radiation oncology programs, the Fellowship and Residency Electronic Interactive Database, the Accreditation Council for Graduate Medical Education, and the Association of American Medical Colleges. We collected data on the gender information of residents in each year (postgraduate years 2-5) and of the faculty (attendings, program director, and chair) during the academic year 2018 to 2019. Spearman's rho test, Pearson's chi-squared test, and Fisher exact tests were used for evaluating the correlation among variables using SPSS version 24. RESULTS: Women constituted 30.8% of radiation oncology residents in the United States in 2019. Eight programs (12.5%) did not have any female residents in their programs, whereas 6 programs (9%) had women constituting more than half of their resident class. The fraction of female medical students applying to radiation oncology over the last 7 years varied between 27% and 33%. Female attending physicians accounted for 30.5% of all the attending physicians in the academic programs. In the leadership positions of the department, the gender gap was wider where only 19 (20%) and 11 (12%) of programs had female program director or chair, respectively. There was a positive correlation between the number of attending physicians and the number of female residents in programs (P = .01). CONCLUSIONS: A significant gender disparity continues to exist among the residents and physicians in the academic radiation oncology departments in the US. This disparity is pronounced in the leadership positions. The results of this study could be used as a benchmark to evaluate the progress that has been made by the efforts to improve gender disparities in radiation oncology.

A Case of Transformation of Primary Cutaneous Follicle Center Lymphoma to Diffuse Large B-Cell Lymphoma Involving the Parotid Gland and Cervical Lymph Nodes.

BACKGROUND Transformation of primary cutaneous follicle center lymphoma (PCFCL), a low-grade B-cell non-Hodgkin lymphoma (NHL), into a high-grade NHL is rare with uncertain prognosis and treatment. A case is reported of a 40-year-old man who presented with a scalp mass that was diagnosed histologically as PCFCL. Imaging of the head and neck identified diffuse large B-cell lymphoma (DLBCL) involving the parotid gland and cervical lymph nodes, which responded well to radiation therapy. CASE REPORT A 40-year-old African American man presented with a two-year history of a progressively enlarging scalp mass that measured 10.5×7.1×6.6 cm. Histology showed a low-grade lymphoma with a follicular pattern. Immunohistochemistry was positive for B-cell markers and Bcl-6, consistent with a diagnosis of PCFCL. Computed tomography (CT) identified a 4.9×3.7×3.4 cm mass in the left parotid gland with bilateral cervical lymphadenopathy that had been present for the previous two or three months. The diagnosis of DLBCL was made on histology from a needle biopsy. Treatment began with rituximab, etoposide, prednisone, vincristine, cyclophosphamide, and doxorubicin (R-EPOCH) chemotherapy, followed by radiation therapy to the scalp, both sides of the neck, and left parotid gland. At four-month follow-up, combined positron emission tomography (PET) and CT showed only diffuse low-level uptake in the scalp and parotid gland. CONCLUSIONS Transformation of low-grade PCFCL to high-grade DLBCL is rare, and the approach to treatment varies. This case showed a good response to chemotherapy and radiation therapy.

#WomenWhoCurie: Leveraging Social Media to Promote Women in Radiation Oncology.

The proportion of female trainees in radiation oncology has generally declined despite increasing numbers of female medical students; as a result, radiation oncology is among the bottom 5 specialties in terms of the percentage of female applicants. Recently, social media has been harnessed as a tool to bring recognition to underrepresented groups within medicine and other fields. Inspired by the wide-reaching social media campaign of #ILookLikeASurgeon to promote female physicians, members of the Society for Women in Radiation Oncology penned a new hashtag and launched the #WomenWhoCurie social media campaign on Marie Curie's birthday November 7th, as part of their strategy to raise public awareness. From November 6, 2018 until November 10, 2018, the #WomenWhoCurie hashtag delivered 1,135,000 impressions, including 408 photos from all over the world including United States, Spain, Canada, France, Australia, Ireland, the United Kingdom, Mexico, Japan, the Netherlands, India, Ecuador, Panama, Brazil, and Nigeria. Alongside continued gender disparity research, social media should continue to be used as a tool to engage the community and spur conversations to formulate solutions for gender inequity.

A Survey Study of Female Radiation Oncology Residents' Experiences to Inform Change.

PURPOSE: Women remain underrepresented at all levels within the field of radiation oncology. We sought to study current female residents' experiences and concerns to inform interventions to promote gender equity. Furthermore, we evaluated interest in a professional society specifically for women radiation oncologists. METHODS AND MATERIALS: An anonymous 76-item survey was designed and distributed to current women residents in radiation oncology in 2017-2018. Analyses describe personal, program, and family characteristics and experiences before and after joining the field. RESULTS: Of 170 female residents surveyed, 125 responded (74% response rate). Over one-quarter were in programs with ≤2 female residents (29%) and ≤2 female attendings (29%). One-third (34%) reported having children. Over half (51%) reported that lack of mentorship affected career ambitions. Over half (52%) agreed that gender-specific bias existed in their programs, and over a quarter (27%) reported they had experienced unwanted sexual comments, attention, or advances by a superior or colleague. Only 5% reported no symptoms of burnout. Almost all (95%) agreed that radiation oncology is perceived as family friendly; however, only 52% agreed that it actually is. An overwhelming majority (90%) expressed interest in joining a professional group for women in radiation oncology. CONCLUSIONS: In the first study to our knowledge to focus specifically on the experiences of women residents in radiation oncology, a number of areas for potential improvement were highlighted, including isolation and underrepresentation, mentorship needs, bias and harassment, and gender-based obstacles such as need for support during pregnancy and motherhood. These findings support the organization of groups such as the Society for Women in Radiation Oncology, which seeks to target these needs to promote gender equity.

Analysis of a real time group consensus peer review process in radiation oncology: an evaluation of effectiveness and feasibility.

BACKGROUND: Peer review systems within radiation oncology are important to ensure quality radiation care. Several individualized methods for radiation oncology peer review have been described. However, despite the importance of peer review in radiation oncology barriers may exist to its effective implementation in practice. The purpose of this study was to quantify the rate of plan changes based on our group peer review process as well as the quantify amount of time and resources needed for this process. METHODS: Data on cases presented in our institutional group consensus peer review conference were prospectively collected. Cases were then retrospectively analyzed to determine the rate of major change (plan rejection) and any change in plans after presentation as well as the median time of presentation. Univariable logistic regression was used to determine factors associated with major change and any change. RESULTS: There were 73 cases reviewed over a period of 11 weeks. The rate of major change was 8.2% and the rate of any change was 23.3%. The majority of plans (53.4%) were presented in 6-10 min. Overall, the mean time of presentation was 8 min. On univariable logistic regression, volumetric modulated arc therapy plans were less likely to undergo a plan change but otherwise there were no factors significantly associated with major plan change or any type of change. CONCLUSION: Group consensus peer review allows for a large amount of informative clinical and technical data to be presented per case prior to the initiation of radiation treatment in a thorough yet efficient manner to ensure plan quality and patient safety.
