BACKGROUND: Triage nurses play a crucial role in addressing patient telephone calls. However, topics that radiation oncology (RO) triage nurses encounter have not been thoroughly investigated.

OBJECTIVES: This project established baseline patient issues addressed via telephone by RO triage nurses in a clinically busy academic RO department; identified themes and potential areas for workflow improvement; and evaluated interprofessional perceptions of RO triage from nurses, physicians, and radiation therapists.

METHODS: This two-part study was conducted from September through November 2021 using a retrospective chart review that analyzed patient communications to the RO nurse triage line. Physicians, nurses, and radiation therapists completed an online survey about their experiences with nurse triage.

FINDINGS: Analysis revealed 13 message themes, with scheduling questions being the most common theme. Survey results indicated that average provider satisfaction with the effectiveness of triage was 3 of 5, perceived triage nurse preparedness to resolve encounters was 3 of 5, and perception of the triage program by physicians was 2.4 of 5.

PURPOSE: In this prospective phase 2 trial, we investigated the toxicity and patient-reported quality-of-life outcomes in patients treated with stereotactic body radiation therapy (SBRT) to the prostate gland and a simultaneous focal boost to magnetic resonance imaging (MRI)-identified intraprostatic lesions while also de-escalating dose to the adjacent organs at risk.

METHODS AND MATERIALS: Eligible patients included low- or intermediate-risk prostate cancer (Gleason score ≤7, prostate specific antigen ≤20, T stage ≤2b). SBRT was prescribed to 40 Gy in 5 fractions delivered every other day to the prostate, with any areas of high disease burden (MRI-identified prostate imaging reporting and data system 4 or 5 lesions) simultaneously escalated to 42.5 to 45 Gy and areas overlapping organs at risk (within 2 mm of urethra, rectum, and bladder) constrained to 36.25 Gy (n = 100). Patients without a pretreatment MRI or without MRI-identified lesions were treated to dose of 37.5 Gy with no focal boost (n = 14).

RESULTS: From 2015 to 2022, a total of 114 patients were enrolled with a median follow-up of 42 months. No acute or late grade 3+ gastrointestinal (GI) toxicity was observed. One patient developed late grade 3 genitourinary (GU) toxicity at 16 months. In patients treated with focal boost (n = 100), acute grade 2 GU and GI toxicity was seen in 38% and 4% of patients, respectively. Cumulative late grade 2+ GU and GI toxicities at 24 months were 13% and 5% respectively. Patient-reported outcomes showed no significant long-term change from baseline in urinary, bowel, hormonal, or sexual quality-of-life scores after treatment.

CONCLUSIONS: SBRT to a dose of 40 Gy to the prostate gland with a simultaneous focal boost up to 45 Gy is well tolerated with similar rates of acute and late grade 2+ GI and GU toxicity as seen in other SBRT regimens without intraprostatic boost. Moreover, no significant long-term changes were seen in patient-reported urinary, bowel, or sexual outcomes from pretreatment baseline.

These NCCN Guidelines for Distress Management discuss the identification and treatment of psychosocial problems in patients with cancer. All patients experience some level of distress associated with a cancer diagnosis and the effects of the disease and its treatment regardless of the stage of disease. Clinically significant levels of distress occur in a subset of patients, and identification and treatment of distress are of utmost importance. The NCCN Distress Management Panel meets at least annually to review comments from reviewers within their institutions, examine relevant new data from publications and abstracts, and reevaluate and update their recommendations. These NCCN Guidelines Insights describe updates to the NCCN Distress Thermometer (DT) and Problem List, and to the treatment algorithms for patients with trauma- and stressor-related disorders.

The specialty of radiation oncology's gender diversity is lagging other medical specialties. The lack of gender diversity in radiation oncology has been demonstrated at all stages of career, from medical schools to department chairs. Multiple articles have demonstrated literature-based benefits of inclusion of a diverse group of female colleagues. This editorial is intended to note areas of progress and highlight resources available to support gender equity in the field of radiation oncology.

OBJECTIVE: Patients are turning to the Internet more often for cancer-related information. Oncology organizations need to ensure that appropriately written information is available for patients online. The aim of this study was to determine whether the readability of radiation oncology online patient information (OPI) provided by RTAnswers (RTAnswers.org, created by the American Society for Radiation Oncology) is written at a sixth-grade level as recommended by the National Institutes of Health (NIH), the U.S Department of Health and Human Services (HHS), and the American Medical Association (AMA).

METHODS: RTanswers.org was accessed and online patient-oriented brochures for 13 specific disease sites were analyzed. Readability of OPI from RTAnswers was assessed using 10 common readability tests: New Dale-Chall Test, Flesch Reading Ease Score, Coleman-Liau Index, Flesch-Kinkaid Grade Level, FORCAST test, Fry Score, Simple Measure of Gobbledygook, Gunning Frequency of Gobbledygook, New Fog Count, and Raygor Readability Estimate.

RESULTS: A composite grade level of readability was constructed using the 8 readability measures that provide a single grade-level output. The grade levels computed by each of these 8 tests were highly correlated (SI alpha = 0.98). The composite grade level for these disease site-specific brochures was 11.6 ± 0.83, corresponding to a senior in high school, significantly higher than the target sixth-grade level (p < 0.05) recommended by the NIH, HHS, and AMA.

CONCLUSION: Patient educational material provided by RTAnswers.org is written significantly above the target reading level. Simplifying and rewording this information could improve patients' understanding of radiation therapy and improve treatment adherence and outcomes.

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.

PURPOSE: Prior surveys suggest almost one-third of chief residents report insufficient exposure to treatment planning. We evaluated the state of treatment planning education among United States residents.

METHODS AND MATERIALS: A web-based survey was sent to current residents identified using the Association of Residents in Radiation Oncology directory.

RESULTS: The response rate was 33%. Twenty-six percent of residents reported a mandatory treatment planning rotation. Seventy-one percent of residents reported reviewing ≤50% of plans with an attending. Twenty-three percent of respondents were not at all or only slightly comfortable (1 or 2 on a 1-5 scale) evaluating treatment plans. Residents with mandatory treatment planning rotations were more comfortable evaluating plans compared with those without mandatory rotations (P = .045). Overall, 60% reported insufficient exposure to treatment planning. Among postgraduate year 5 residents, this rate was 52%. Ninety-two percent of residents expressed interest in free supplemental treatment planning resources.

CONCLUSIONS: A significant proportion of residents surveyed report insufficient exposure to treatment planning. Development of a practical treatment planning curriculum would offer the opportunity to improve resident education, and ultimately quality of care, at the national level.

PURPOSE: The aim of this study is to report the American Society for Radiation Oncology 2017 radiation oncologist (RO) workforce survey results; identify demographic, technology utilization, and employment trends; and assess the profession's ability to meet patients' needs, offer job satisfaction, and attract high-caliber trainees.

METHODS: In spring 2017, the American Society for Radiation Oncology distributed an online survey to 3856 US RO members. The questionnaire was patterned after the 2012 workforce survey for trend analysis. The 31% response rate yielded 1174 individual responses (726 practices) for analysis.

RESULTS: ROs' mean age was 50.9 years. Compared to 2012, female representation (28.9%) increased and white representation (69.8%) dropped. The proportion in rural practice (12.6%) decreased, whereas the number of suburban ROs (40.6%) increased and urban ROs (46.8%) remained high. Most ROs worked full-time, averaging 51.4 h/wk. Stereotactic body radiation therapy, cone beam computed tomography, and magnetic resonance/positron emission tomography-computed tomography fusion utilization increased, whereas low-dose-rate brachytherapy decreased by >15 percentage points. Hypofractionation utilization was 95.3% and was highest in academic/university systems and lowest in private solo practices (P < .001). More respondents were concerned about an RO oversupply rather than shortage. ROs reported 250 consults (median) and 20 on-treatment patients (median) in 2016 and greater time allocation to electronic health record management compared with 3 years earlier. Approximately 15% of ROs reported job vacancies, which were more prevalent in urban practices and academic/university systems. ROs were employed by academic/university systems, private practices, and nonacademic hospitals in a respective ratio of 2:2:1. Comparison with 2012 survey findings showed a shift from private practice toward academic/university systems and nonacademic hospitals. Compensation was predominantly productivity-based at private practices and a fixed salary or a base salary at academic/university systems and nonacademic hospitals. Practice merger/buyout was the lead reason for ROs to change employers.

CONCLUSIONS: Since 2012, race and gender gaps narrowed, but geographic disparities persisted, with ROs gravitating toward resource-rich suburban and urban locations over rural practices. The workforce has shifted from predominantly private practice to more equal balance with academic/university systems. These findings reflect the current US RO landscape and serve to underscore the need for collective action to ensure equitable RO care for all patients.

PURPOSE: To investigate interobserver delineation variability for gross tumor volumes of primary lung tumors and associated pathologic lymph nodes using magnetic resonance imaging (MRI), and to compare the results with computed tomography (CT) alone- and positron emission tomography (PET)-CT-based delineations.

METHODS AND MATERIALS: Seven physicians delineated the tumor volumes of 10 patients for the following scenarios: (1) CT only, (2) PET-CT fusion images registered to CT ("clinical standard"), and (3) postcontrast T1-weighted MRI registered with diffusion-weighted MRI. To compute interobserver variability, the median surface was generated from all observers' contours and used as the reference surface. A physician labeled the interface types (tumor to lung, atelectasis (collapsed lung), hilum, mediastinum, or chest wall) on the median surface. Contoured volumes and bidirectional local distances between individual observers' contours and the reference contour were analyzed.

RESULTS: Computed tomography- and MRI-based tumor volumes normalized relative to PET-CT-based volumes were 1.62 ± 0.76 (mean ± standard deviation) and 1.38 ± 0.44, respectively. Volume differences between the imaging modalities were not significant. Between observers, the mean normalized volumes per patient averaged over all patients varied significantly by a factor of 1.6 (MRI) and 2.0 (CT and PET-CT) (P=4.10 × 10-5 to 3.82 × 10-9). The tumor-atelectasis interface had a significantly higher variability than other interfaces for all modalities combined (P=.0006). The interfaces with the smallest uncertainties were tumor-lung (on CT) and tumor-mediastinum (on PET-CT and MRI).

CONCLUSIONS: Although MRI-based contouring showed overall larger variability than PET-CT, contouring variability depended on the interface type and was not significantly different between modalities, despite the limited observer experience with MRI. Multimodality imaging and combining different imaging characteristics might be the best approach to define the tumor volume most accurately.

PURPOSE: To report updated feasibility and reproducibility results for high-dose-rate noninvasive breast brachytherapy (NIBB) for tumor bed boost with whole breast radiation therapy (WBRT) in the setting of expanded patient and treatment facility number.

METHODS AND MATERIALS: Fifteen independent community-based and academic centers reported 518 early-stage breast cancer patients from July 2007 to February 2015 on a privacy-encrypted online data registry. All patients' treatment included lumpectomy followed by combination of WBRT and NIBB. NIBB was completed with commercially available (AccuBoost, Billerica, MA) mammography-based system using high-dose-rate 192Ir emissions along orthogonal axes. Harvard scale was used to grade cosmesis.

RESULTS: Total patient cohort had median followup of 12 months (1-75 months) with subset of 268 having available cosmesis. Greater than 2- and 3-year followup was 29% and 14%, respectively. Entire cohort had 97.4% excellent/good (E/G) breast cosmesis and freedom from recurrence of 97.6% at the final followup. WBRT timing with respect to NIBB delivery demonstrated no statistically significant difference in E/G cosmesis. Achieved E/G cosmesis rate was also not statistically significant (χ2p-value = 0.86) between academic and community institutions with 97.8% vs. 96.6%.

CONCLUSIONS: NIBB represents an alternative method for delivery of breast tumor cavity boost that has shown feasibility in a diverse group of both academic and community-based practices with reproducible early cosmesis and tumor control results. Recommendations are updated noting ideal timing of boost delivery likely to be before or early during WBRT given equal cosmesis and less documented treatment discomfort.

PURPOSE: Palmar and plantar fibromatosis (PPF) is a progressive connective tissue disorder of the hand/foot that often leads to debilitating functional impairment. In Europe, orthovoltage radiation therapy (RT) has been demonstrated to prevent local disease progression for up to 80% of patients with early-stage PPF. There are limited data reporting outcomes for populations outside of Europe or using electron RT.

METHODS AND MATERIALS: Between 2008 and 2013, 44 early-stage PPF cases received RT. RT fields involved clinically defined targets encompassing involved areas (skin changes, cords, nodules) with at least 1.5-cm margins. En face electrons (6-12 MeV) and bolus (0.5-1 cm) were selected individually. Outcomes are reported for patients who participated in an institutional review board-approved standardized questionnaire and chart review.

RESULTS: Thirty-three patients received 66 treatments (45 hands/15 feet and 6 reirradiations). Most frequent dose schemes were 21 Gy (3 Gy in 7 fractions) and 30 Gy (3 Gy in 10 fractions with 6- to 8-week breaks after 15 Gy). Median time to follow-up survey was 31 months. Disease progression at any location within or outside the RT treatment field occurred in 20 of 33 patients (61%). Fourteen of 60 sites (23%) developed in-field progression, but 4 sites were successfully reirradiated with final local control in 50 of 60 sites (83%). RT improved pretreatment symptoms of pain with strain at 30 of 37 sites (81%) and itch/burn sensations at 17 of 21 sites (81%). There were no reported grade ≥2 late toxicities even with reirradiation. Patient reported overall success with treatment was 31 of 33 patients (94%).

CONCLUSION: PPF is a progressive disease. En face electron RT is an effective therapy that stabilizes or improves symptoms in the majority of patients. Reirradiation can be considered as a treatment option for in-field progression. Patients report minimal toxicity and a high rate of satisfaction with treatment.

PURPOSE: A majority of patients enrolled in hospice have advanced cancer. Most of them are burdened by symptoms related to uncontrolled tumor growth. Although palliative radiation therapy (RT) is highly effective, only 1% of hospice patients are ever referred. Commonly cited concerns include high treatment cost, burden of travel for multiple visits, and a perceived reluctance of radiation oncologists to deliver single-fraction RT.

METHODS: A clinic offering affordable RT to patients in hospice was developed to simplify the intake, reduce cost, and minimize travel to a single visit. The goal was to evaluate, simulate and plan treatment, and treat patients with a single fraction of palliative RT within a 4-hour period.

RESULTS: The initial 18-month experience is reported in this Health Information Portability and Accountability Act-compliant report that was approved by the Virginia Commonwealth University Institutional Review Board. Eight referrals were received from local hospice agencies that had not referred any patients in previous years. A telephone screening process avoided unnecessary travel for two patients who were not candidates for RT. Two additional patients who were evaluated with a same-day computed tomography simulation were not good candidates for RT. Ultimately, four patients were successfully treated with single-fraction palliative RT of 8 Gy. None had to disenroll from hospice.

CONCLUSION: This novel program increased access to palliative RT for patients in hospice who would otherwise not have been referred. The main challenge identified was a need for ongoing educational activities at hospice agencies where staff turnover may be high and understanding about palliative RT can be limited.

Single-walled carbon nanotubes (SWNTs), being hydrophobic by nature, aggregate in water to form large bundles. However, isolated SWNTs possess unique physical and chemical properties that are desirable for sensing and biological applications. Conventionally isolated SWNTs can be obtained by wrapping the tubes with biopolymers or surfactants. The binding modes proposed for these solubilization schemes, however, are less than comprehensive. Here we characterize the efficacies of solubilizing SWNTs through various types of phospholipids and other amphiphilic surfactants. Specifically, we demonstrate that lysophospholipids, or single-chained phospholipids offer unprecedented solubility for SWNTs, while double-chained phospholipids are ineffective in rendering SWNTs soluble. Using transmission electron microscopy (TEM) we show that lysophospholipids wrap SWNTs as striations whose size and regularity are affected by the polarity of the lysophospholipids. We further show that wrapping is only observed when SWNTs are in the lipid phase and not the vacuum phase, suggesting that the environment has a pertinent role in the binding process. Our findings shed light on the debate over the binding mechanism of amphiphilic polymers and cylindrical nanostructures and have implications on the design of novel supramolecular complexes and nanodevices.
