    Abstract Financial toxicity details the financial burden patients face due to a variety of medical costs. Cancer patients, especially those receiving radiation therapy, are at a much higher risk of experiencing economic hardships than healthy people or people with other conditions. There are a variety of risk factors associated with financial toxicity as well as numerous tools to assess the toxicity experienced by patients. In this review article, we present a concise overview of contributors, risk factors, case studies, tools, impacts, and potential interventions of financial toxicity.

    Abstract Purpose: Stereotactic body radiation therapy (SBRT) is commonly used to treat spinal metastases in combination with immunotherapy (IT). The optimal sequencing of these modalities is unclear. This study aimed to investigate whether sequencing of IT and SBRT was associated with differences in local control (LC), overall survival (OS), and toxicity when treating spine metastases.
    Methods and materials: All patients at our institution who received spine SBRT from 2010 to 2019 with systemic therapy data available were reviewed retrospectively. The primary endpoint was LC. Secondary endpoints were toxicity (fracture and radiation myelitis) and OS. Kaplan-Meier analysis was used to determine whether IT sequencing (before versus after SBRT) and use of IT were associated with LC or OS.
    Results: A total of 191 lesions in 128 patients met inclusion criteria with 50 (26%) lesions in 33 (26%) patients who received IT. Fourteen (11%) patients with 24 (13%) lesions received the first IT dose before SBRT, whereas 19 (15%) patients with 26 (14%) lesions received the first dose after SBRT. LC did not differ between lesions treated with IT before SBRT versus after SBRT (1 year 73% versus 81%, log rank = 0.275,
    Conclusions: Sequencing of IT and SBRT was not associated with any difference in LC or toxicity, but delivering IT after SBRT versus before SBRT was associated with improved OS.

    Abstract Background: Gastrointestinal Stromal Tumors (GISTs) are the most common mesenchymal tumors of the GI tract. SEER is an extensive cancer database which proves useful in analyzing population trends. This analysis investigated GIST outcomes between geriatric & non-geriatric patients.
    Methods: SEER*STAT 8.4.0.1 was used to extract relevant GIST data from 2000 to 2019. Geriatric age was defined as ≥70 years. Variables included age, sex, surgery, cancer-specific death, and overall survival. Statistical tests included univariate analysis using KM survival estimate (95% confidence interval) to calculate 5-year survival (5YS). Log-Rank tests determined statistical significance. Multivariable Cox's PH regression estimated the geriatric hazard death ratio adjusted for sex, stage, and surgery.
    Results: The number of patients included was 13,579, yielding overall 5YS of 68.6% (95% CI 67.7-69.5). Cancer-specific death was 39.11% in 2000 & 3.33% in 2019. Non-geriatric & geriatric patient data yielded 5YS of 77.4% (76.4%-78.3%) and 53.3% (51.7%-54.8%) respectively (p < 0.0001). For no surgery/surgery, younger patient data yielded 5YS of 48.7% (45.8%-51.4%) and 83.7% (82.7%-84.7%) respectively (p < 0.0001); geriatric data yielded 5YS of 29.3% (26.5%-32.1%) and 62.8% (60.8%-64.6%) respectively (p < 0.0001). Multivariable analysis yielded a geriatric hazard death of 2.56 (2.42-2.70) (p < 0.0001).
    Conclusions: Cancer-specific death decreased since 2000, indicating an improvement in survival & treatment methods. Observed lower survival rates overall in the geriatric group. Surgery appeared to enhance survival rates in both groups, suggesting that surgery is an important factor in GIST survival regardless of age. Large prospective studies will help define clinical management for geriatric patients.

    Abstract Purpose: Full-length vaginal (FLV) brachytherapy for patients with endometrial cancer and high-risk features should be considered as per the American Brachytherapy Society to reduce distal vaginal recurrence in patients with endometrial cancers with papillary serous/clear cell histologies, grade 3 status, or extensive lymphovascular invasion. We sought to investigate this patient population and report outcomes of treatment with high-dose-rate (HDR) brachytherapy in women treated with FLV brachytherapy versus partial-length vaginal (PLV) brachytherapy.
    Methods and materials: With institutional review board approval, we identified patients with endometrial cancer meeting American Brachytherapy Society criteria of high-risk features treated with adjuvant HDR between 2004 and 2010. HDR doses were 21Gy in 3 fractions delivered to either the full-length or partial-length vagina. Acute and late toxicities were evaluated using the Radiation Therapy Oncology Group scale and Radiation Therapy Oncology Group/European Organisation for Research and Treatment of Cancer grading, respectfully. Vaginal recurrences were assessed by physical examination and pap smears. Statistical analyses were performed using SPSS version 23 software.
    Results: Of 240 patients treated with HDR brachytherapy, 121 were treated with FLV brachytherapy, and 119, with PLV brachytherapy. The median follow-up was 9.5 years (range, 8-11 years) for FLV patients and 8.5 years (range, 7-10 years) for PLV patients; 0% of patients had vaginal recurrences, and 1.4% and 0.9% had proximal vaginal recurrences, respectively (P = .54). All patients treated with FLV brachytherapy developed grade 3 mucositis of the lower vagina/introitus (P < .0001) and had increased analgesics use compared with those treated with PLV brachytherapy (P < .0001). In total, 23% of patients treated with FLV brachytherapy developed grade 3 stenosis of the lower vagina/introitus, in contrast to 0% of patients treated with PLV brachytherapy (P < .0001).
    Conclusions: PLV brachytherapy is as effective as FLV brachytherapy in reducing local recurrence and causes a significantly lower incidence of acute and late toxicities. The results of this study caution radiation oncologists regarding the careful use of FLV brachytherapy in patients with endometrial cancer and high-risk features.

    Abstract Symptomatic spinal metastasis is a frequent complication of cancer that had been treated, until relatively recently, with primitive techniques to modest radiation dose levels, with a baseline assumption of limited survival and poor patient performance in that setting. In the era of targeted and personalized therapies, many patients are living longer and more functionally and are able to manage their disease on the model of chronic illness. Given these developments, an attractive option is the use of stereotactic body radiation therapy (SBRT) to deliver high biologically effective doses of radiation conformally to maximize the palliative gains of treatment. However, randomized data to guide practice are scarce. We review the extant literature and present an algorithmic approach to selecting patients with metastatic disease for palliative spinal SBRT favoring the results of available randomized studies and remaining within the safety constraints supported by evidence from randomized trials.

    Abstract Purpose: Mindfulness, defined as awareness of the moment while acknowledging and accepting one's feelings, thoughts, and sensations, is the aim of mindfulness meditation. Our objective was to investigate the relationship between burnout, mindfulness, fulfillment, and other personal characteristics in radiation oncology (RO) residents/attendings compared with other specialties.
    Methods and materials: From December 2019 to February 2020, residents and attendings in multiple specialties at a single tertiary care academic institution were sent surveys, including the mindfulness attention awareness scale, Stanford professional fulfillment index, and a personal questionnaire. A Pearson correlation was conducted on the relationship between mindfulness, fulfillment, disengagement, and exhaustion. To determine risk factors for burnout (overall burnout ≥ 1.33), a univariate analysis was conducted to yield odds ratios (ORs) on debt, specialty, income, sleep, exercise, marital status, number of children, work hours, mindfulness (mindfulness attention awareness scale ≥ 4), fulfillment (professional fulfillment ≥ 3), and time with family/friends. Significant factors on univariate analysis were entered into multivariate analysis.
    Results: There were 180 surveys completed by 60 residents and attendings across 17 specialties. Eighteen (30%) respondents were in RO. Mindfulness positively correlated with fulfillment (
    Conclusions: RO physicians experienced less burnout than physicians in other specialties at our institution. Mindfulness, professional fulfillment, moderate work hours, and spending time with loved ones protected against burnout. Further study of interventions to promote mindfulness and fulfillment may help us understand how best to improve the mental and emotional health of RO physicians.

    Abstract Introduction: The underlying factors that contribute to early radiotherapy (RT) termination are understudied, especially in the era of hypofractionated treatment regimens. In this retrospective investigation, we examined the characteristics and causes of premature RT terminations in senior adults (>70 years old) with oral cavity (OC) and laryngeal carcinomas.
    Methods: Hundred and eighty-eight patients treated with RT ± systemic therapy for OC and laryngeal cancer from 2017 to 2022 were identified. Premature termination was defined as completion of less than 95% of the prescribed RT. Logistic regression analysis was performed to examine factors predictive of premature termination, and survival was determined using the Kaplan-Meier method.
    Results: Twenty patients (10.6%) experienced premature RT terminations. On regression analysis, ECOG score at initiation of RT was the only covariate studied to be independently associated with premature termination (OR 2.00, 95%CI: [1.21, 3.30], p = 0.007). Three-year overall survival (49.1% vs. 77.3%) was significantly reduced in the termination cohort (p < 0.0001).
    Conclusions: This analysis demonstrated over 1 in 10 patients had premature RT termination, which prognosticated inferior survival outcomes. Poor performance status may highlight patients at risk for premature termination and thus identify good candidates for hypofractionated protocols.

    Abstract Objective The goal of this study is to compare the effectiveness of three different meditation techniques (two internal focus techniques and one external focus technique) using a low-cost portable electroencephalography (EEG) device, namely, MUSE, for an objective comparison. Methods This is an IRB-approved retrospective study. All participants in the study were healthy adults. Each study participant (n = 34) was instructed to participate in three meditation sessions: mantra (internal), breath (internal), and external point. The MUSE brain-sensing headband (EEG) was used to document the "total time spent in the calm state" and the "total time spent in the calm or neutral state" (outcomes) in each three-minute session to conduct separate analyses for the meditation type. Separate generalized linear models (GLM) with unstructured covariance structures were used to examine the association between each outcome and the explanatory variable (meditation type). For all models, if there was a significant association between the outcome and the explanatory variable, pairwise comparisons were carried out using the Tukey-Kramer correction. Results The median time (in seconds) spent in the calm state while practicing mantra meditation was 131.5 (IQR: 94-168), while practicing breath meditation was 150 (IQR: 113-164), and while practicing external-point meditation was 100 (IQR: 62-126). Upon analysis, there was a significant association between the meditation type and the time spent in the calm state (p-value = 0.0006). Conclusion This is the first study comparing "internal" versus "external" meditation techniques using an objective measure. Our study shows the breath and mantra technique as superior to the external-point technique as regards time spent in the calm state. Additional research is needed using a combination of "EEG" and patient-reported surveys to compare various meditative practices. The findings from this study can help incorporate specific meditation practices in future mindfulness-based studies that are focused on healthcare settings and on impacting clinical outcomes, such as survival or disease outcomes.

    Abstract Purpose: Patient experience tools are used throughout health care to evaluate physician and departmental performance. In radiation medicine, these tools are important in evaluating patient-specific metrics throughout their care journey. This study compared patient experience outcomes from a central tertiary cancer program with network clinics in a health care network.
    Methods and materials: Radiation medicine patient experience surveys (Press Ganey, LLC) were collected from a central facility and 5 network locations from January 2017 through June 2021. Surveys were distributed to patients after treatment completion. The study cohort was divided into the central facility and satellites. Questions were converted to a 0 to 100 scale from the Likert scale (1-5). To compare scores between site types, 2-way analysis of variance tests for the significance of sites adjusted for years of operations and adjustments for multiple comparisons (Dunnett's test) were completed on each question.
    Results: The number of consecutively returned surveys analyzed was 3777; a response rate of 33.3% was observed. The central site conducted 117,583 linear accelerator, 1425 Gamma Knife, 273 stereotactic radiosurgery, and 830 stereotactic body radiation therapy procedures. All satellites combined conducted 76,788 linear accelerator, 131 Gamma Knife, 95 stereotactic radiosurgery, and 355 stereotactic body radiation therapy procedures. The central facility fared better than the satellites on "Convenience of parking" (95.9 vs 87.9;
    Conclusions: All sites yielded exemplary patient experience rates. Community clinics scored higher than the main campus. The higher scores at the network sites require a deeper analysis of factors influencing the central facility, as the survey did not account for varying patient volumes and disparities in care complexity across sites. Attributes to satellites include lower patient volumes and easily navigable layouts. These results counter the impression that increased resources at the main campus create a better patient experience relative to network clinics and suggest that high-volume tertiary facilities will require unique initiatives to improve the patient experience.

    Abstract The role of radiation therapy in melanoma has evolved over the last few decades. There has been a dramatic improvement in radiation delivery with the introduction of intensity-modulated radiation therapy, image-guided radiation therapy, stereotactic radiosurgery, and stereotactic body radiation therapy/stereotactic radiation therapy. More recently, with the introduction of immunotherapy in various malignancies, including melanoma, the role of radiation therapy is being reevaluated. This article describes the evolution of the role of radiation therapy from nonimmunotherapy to the era of immunotherapy.
