Purpose: Sexual and gender minority (SGM) individuals have an increased risk of poor health outcomes, in part due to knowledge and training gaps in health care education. This study sought to evaluate the knowledge, attitudes, and practice behaviors of various health care role groups within radiation oncology toward SGM patients. Methods and Materials: A 38-item web-based survey was emailed to 1045 staff across 2 large radiation oncology departments. The survey assessed demographics, attitudes, knowledge, and practice behaviors. χ2 tests were performed to explore differences in survey responses by age, political affiliation, religious identity, year since graduation, and role groups. One-way analysis of variance tests were conducted to determine differences between respondents’ confidence in knowledge and performance on the knowledge section of the survey. Thematic analysis was applied to the open discussion section. Results: Of the 223 respondents, 103 clinicians (physicians/advanced practice providers/nurses) and 120 nonclinicians (administrative staff, medical assistants, and other nonmedical staff) participated in the survey (21.3% response rate): 72.6% answered the knowledge questions; 93.5% stated they were comfortable treating sexual minorities, or lesbian, gay, bisexual, and queer + patients; 88% indicated comfort in treating transgender patients; 36.6% stated they were confident in their knowledge of the health needs of transgender patients; and 50.3% expressed confidence in treating lesbian, gay, bisexual, and queer + patients. Fewer nonclinicians than clinicians thought that gender identity, sexual orientation, and sex assigned at birth were important to provide the best care (P < .05). The open comments section identified key themes, including the belief that current educational tools are not helpful, desire for more educational formats (lectures, case-based learning, seminars), and an overall interest in SGM health education. Conclusions: Most staff feel comfortable in treating SGM patients but are less confident in the distinct needs of this population. Knowledge gaps persist for both clinicians and nonclinicians, indicating a need for further training specific to oncology care.

Purpose: The use of large-field external beam reirradiation (re-RT) after pelvic radiation therapy (RT) for genitourinary (GU) cancers has not been reported. We report the results of such treatment in patients with either symptomatic GU second malignant neoplasms or locally recurrent pelvic tumors after initial RT for whom surgery or further systemic therapy was not an option. Methods and materials: The records of 28 consecutive patients with advanced, bulky GU malignancies treated with high-dose, large-field re-RT with palliative intent between 2008 and 2014 were retrospectively reviewed. Descriptive outcome analyses focused on toxicities and symptom control, and responses were evaluated by 2 independent observers. Results: Twenty-seven male patients (96%) were included. Median initial external beam RT dose was 64 Gy (range, 30-75.6 Gy). The median time between initial RT and re-RT was 9.5 years (range, 0.2-32 years). At the time of re-RT, there were 16 local recurrences and 12 second malignant neoplasms together comprising 16 bladder, 10 prostate, 1 ureteral, and 1 penile cancer. Indications for re-RT were pain and bleeding/hemorrhage. The median equivalent sphere diameter planning target volume for re-RT was 8.6 cm (range, 4.7-16.3 cm). Given the severity of the symptoms and the bulk of the disease at the time of re-RT, a higher dose of RT was administered. The median re-RT dose was 50 Gy (range, 27.5-66 Gy).
