RESUMO
PURPOSE: Electron paramagnetic resonance (EPR) biodosimetry, used to triage large numbers of individuals incidentally exposed to unknown doses of ionizing radiation, is based on detecting a stable physical response in the body that is subject to quantifiable variation after exposure. In vivo measurement is essential to fully characterize the radiation response relevant to a living tooth measured in situ. The purpose of this study was to verify EPR spectroscopy in vivo by estimating the radiation dose received in participants' teeth. METHODS AND MATERIALS: A continuous wave L-band spectrometer was used for EPR measurements. Participants included healthy volunteers and patients undergoing head and neck and total body irradiation treatments. Healthy volunteers completed 1 measurement each, and patients underwent measurement before starting treatment and between subsequent fractions. Optically stimulated luminescent dosimeters and diodes were used to determine the dose delivered to the teeth to validate EPR measurements. RESULTS: Seventy measurements were acquired from 4 total body irradiation and 6 head and neck patients over 15 months. Patient data showed a linear increase of EPR signal with delivered dose across the dose range tested. A linear least-squares weighted fit of the data gave a statistically significant correlation between EPR signal and absorbed dose (P < .0001). The standard error of inverse prediction (SEIP), used to assess the usefulness of fits, was 1.92 Gy for the dose range most relevant for immediate triage (≤7 Gy). Correcting for natural background radiation based on patient age reduced the SEIP to 1.51 Gy. CONCLUSIONS: This study demonstrated the feasibility of using spectroscopic measurements from radiation therapy patients to validate in vivo EPR biodosimetry. The data illustrated a statistically significant correlation between the magnitude of EPR signals and absorbed dose. The SEIP of 1.51 Gy, obtained under clinical conditions, indicates the potential value of this technique in response to large radiation events.

Background: Sporadic inclusion body myositis (sIBM) is a rare and slowly progressive skeletal muscle disease that can cause hand dysfunction, which is a major source of disability. Tendon transfers have been reliably used to improve function in other neuromuscular settings. Given that sIBM patients often present with flexion impairments and mostly functioning extensors, we investigated the potential opportunity for tendon transfer surgery to improve hand dysfunction in sIBM patients. Methods: We conducted a scoping review for studies of sIBM and tendon transfers, extracted descriptions of hand function and surgical technique, and recorded results in terms of hand function. We also conducted an institutional review board-approved survey with 470 participants to determine baseline patient-reported function and to determine participant perceptions and expectations for tendon transfer surgery to improve hand function in sIBM. Results: We identified three published case reports on tendon transfers in sIBM patients with subjectively improved grip and pinch strength, but standardized measures of hand function or quality-of-life were not reported. Within the surveyed cohort, half of participants reported that they would consider surgery, yet only 8% had been referred to a hand surgeon. Fifty four percent of participants reported that they would consider surgery if there would be 1-2 years of benefit after surgery. All participants who would consider surgery also had significant upper extremity disability. Discussion: Tendon transfer surgery has the potential to improve quality-of-life for sIBM patients, and there is significant patient interest in this approach. To objectively assess its efficacy, we propose conducting a surgical trial.
RESUMO
Background Mycosis fungoides (MF) is the most common form of cutaneous T-cell lymphoma (CTCL). Although it often has an indolent course, it can progress to more aggressive CTCL forms. There is sparse data in current literature describing specific clinical factors associated with in-hospital mortality in mycosis fungoides patients. An understanding of patients at greatest risk for in-hospital mortality can aid in developing recommendations for prophylaxis and empirical management. Aim We aim to characterize factors associated with in-hospital mortality in MF patients. Materials and methods The Nationwide Emergency Department Sample (NEDS) was queried for MF cases from 2006 to 2015. Baseline demographic and hospital characteristics were stratified based on survival outcomes. Multivariable logistic regression was used to identify factors associated with in-hospital mortality. Results A total of 57,665 patients with MF presenting to the ED between 2006 and 2015 were identified. Sézary syndrome, sepsis, and advanced age were associated with MF in-hospital mortality, while female sex was inversely associated. There was a downtrend in in-hospital mortality among MF patients presenting to the ED from 2006 to 2015. Conclusions Our study highlights factors crucial for risk-stratification for hospitalized MF patients.
RESUMO
BACKGROUND: Although deep inspiratory breath-hold (DIBH) is routinely used for left-sided breast cancers, its benefits for right-sided breast cancer (rBC) have yet to be established. We compared free-breathing (FB) and DIBH treatment plans for a cohort of rBC undergoing regional nodal irradiation (RNI) to determine its potential benefits. METHODS AND MATERIALS: rBC patients considered for RNI (internal mammary nodal chains, supraclavicular field, with or without axilla) from October 2017 to May 2020 were included in this analysis. For each patient, FB versus DIBH plans were generated and dose volume histograms evaluated the following parameters: mean lung dose, ipsilateral lung V20/V5 (volumes of lung receiving 20 Gy and 5 Gy, respectively); mean heart dose and heart V5 (volumes of heart receiving 5 Gy); liver V20 absolute /V30 absolute (absolute volume of liver receiving 20 Gy and 30 Gy, respectively), liver Dmax, and total liver volume irradiated (TVIliver). The dosimetric parameters were compared using Wilcoxon signed-rank testing. RESULTS: Fifty-four patients were eligible for analysis, comparing 108 FB and DIBH plans. DIBH significantly decreased all lung and liver parameters: mean lung dose (19.7 Gy-16.2 Gy, P < .001), lung V20 (40.7%-31.7%, P < .001), lung V5 (61.2%-54.5%, P < .001), TVIliver (1446 cc vs 1264 cc; P = .006) liver Dmax (50.2 Gy vs 48.9 Gy; P = .023), liver V20 (78.8-23.9 cc, P < .001), and liver V30 (58.1-14.6 cc, P < .001) compared with FB. DIBH use did not significantly improve heart parameters, although the V5Heart trended on significance (1.25-0.6, P = .067). CONCLUSIONS: This is the largest cohort to date analyzing DIBH for RNI-rBC. Our findings demonstrate significant improvement in all lung and liver parameters with DIBH, supporting its routine consideration for rBC patients undergoing comprehensive RNI.

PURPOSE: Peer review during physician chart rounds is a major quality assurance and patient safety step in radiation oncology. However, the effectiveness of chart rounds in detecting problematic treatment plans is unknown. We performed a prospective blinded study of error detection at chart rounds to clarify the effectiveness of this quality assurance step. METHODS AND MATERIALS: Radiation Oncology Incident Learning System publications were queried for problematic plans approved for treatment that would be detectable at chart rounds. A resident physician, physicist, and dosimetrist collaboratively generated 20 treatment plans with simulated errors identical in nature to those reported to the Radiation Oncology Incident Learning System. These were inserted randomly into weekly chart rounds over 9 weeks, with a median of 2 problematic plans presented per chart rounds (range, 1-4). Data were collected on detection, attendance, length, and number of cases presented at chart rounds. Data were analyzed using descriptive statistics and univariable logistic regression with odds ratios. RESULTS: The median length of chart rounds over the study period was 60 minutes (range, 42-79); median number of cases presented per chart rounds was 45 (range, 38-50). The overall detection rate was 55% (11 of 20). Detection rates were higher for cases presented earlier in chart rounds: 75% versus 25% of problematic plans were detected within 30 minutes of start of chart rounds versus after 30 minutes (odds ratio, 0.11; 95% confidence interval, 0.01-0.88; P = .037). Detection rates showed a trend toward increase during the study period but this was not significant: 33% in weeks 1 to 5 and 73% during weeks 6 to 9 (5.3; 95% confidence interval, 0.78-36; P = .08). CONCLUSIONS: The detection of clinically significant problematic plans during chart rounds could be significantly improved. Problematic plans are more frequently detected earlier in chart rounds and inserting such plans into chart rounds may enhance detection; however, larger studies are needed to confirm these findings. A multi-institutional study is planned.

We report results on 23 patients with cutaneous T cell lymphoma (7 primary cutaneous γδ T cell lymphoma [PCGDT], 16 mycosis fungoides/Sézary syndrome [MF/SS]) who underwent allogeneic stem cell transplantation. All pts had skin involvement, 14 had total skin electron beam before conditioning. Donors were 10/10 HLA matched related (13), 5/10 haploidentical (4), and matched unrelated (5) or mismatched unrelated (1). Thirteen were in a clinical complete remission at the time of transplant. The 100-day transplant related mortality for the MF/SS and PCGDT patients was 12% and 29%, respectively. At a median follow up of 5.5 years, the overall survival and disease-free survival for MF/SS patients was 75% and 64%, respectively, and 6 of 10 MF/SS pts in long term complete response had a partial response at the time of transplant. Of seven PCGDT patients, four of seven are alive at a median follow up of 5 years and three are disease-free.

During the coronavirus disease 2019 (COVID-19) pandemic, providers and patients must engage in shared decision making regarding the pros and cons of early versus delayed interventions for localized skin cancer. Patients at highest risk of COVID-19 complications are older; are immunosuppressed; and have diabetes, cancer, or cardiopulmonary disease, with multiple comorbidities associated with worse outcomes. Physicians must weigh the patient's risk of COVID-19 complications in the event of exposure against the risk of worse oncologic outcomes from delaying cancer therapy. Herein, the authors have summarized current data regarding the risk of COVID-19 complications and mortality based on age and comorbidities and have reviewed the literature assessing how treatment delays affect oncologic outcomes. They also have provided multidisciplinary recommendations regarding the timing of local therapy for early-stage skin cancers during this pandemic with input from experts at 11 different institutions. For patients with Merkel cell carcinoma, the authors recommend prioritizing treatment, but a short delay can be considered for patients with favorable T1 disease who are at higher risk of COVID-19 complications. For patients with melanoma, the authors recommend delaying the treatment of patients with T0 to T1 disease for 3 months if there is no macroscopic residual disease at the time of biopsy. Treatment of tumors ≥T2 can be delayed for 3 months if the biopsy margins are negative. For patients with cutaneous squamous cell carcinoma, those with Brigham and Women's Hospital T1 to T2a disease can have their treatment delayed for 2 to 3 months unless there is rapid growth, symptomatic lesions, or the patient is immunocompromised. The treatment of tumors ≥T2b should be prioritized, but a 1-month to 2-month delay is unlikely to worsen disease-specific mortality. For patients with squamous cell carcinoma in situ and basal cell carcinoma, treatment can be deferred for 3 months unless the individual is highly symptomatic.

PURPOSE: Burnout in the medical workforce leads to early retirement, absenteeism, career changes, financial losses for medical institutions, and adverse outcomes for patients. Recent literature has explored burnout in different specialties of medicine. This article examines burnout among medical oncology trainees and identifies factors associated with burnout and professional dissatisfaction, including socioeconomic factors. METHODS: US medical oncology programs were sent a survey that included the Maslach Burnout Index-Human Services Survey as well as demographic, socioeconomic, and program-specific questions tailored to medical oncology fellowship. Primary binary end points included burnout, satisfaction with being a physician, and satisfaction with being a medical oncologist. Binomial logistic models determined associations between various characteristics and end points. RESULTS: Overall, 261 US fellows completed the survey. Seventy percent of international medical graduates reported no educational debt, whereas only 36% of US graduates reported no educational debt. Eighty-two percent of survey respondents reported their mother had at least a bachelor's degree, and 87% of respondents reported their father had at least a bachelor's degree. At least 27% of respondents had symptoms of burnout. Factors inversely associated with burnout on multivariable analysis included having a mother who graduated college (odds ratio [OR], 0.27), reporting an adequate perceived balance between work and personal life (OR, 0.22), feeling that faculty care about educational success (OR, 0.16), and being in the final year of training (OR, 0.45). Having debt ≥ $150,000 (OR, 2.14) was directly associated with burnout. CONCLUSION: Symptoms of burnout are common among medical oncology fellows and are associated with educational debt and socioeconomic factors.

Effective treatments for respiratory syncytial virus (RSV) infection are lacking. Here, we report a human proof-of-concept study for RV521, a small-molecule antiviral inhibitor of the RSV-F protein. In this randomized, double-blind, placebo-controlled trial, healthy adults were challenged with RSV-A Memphis-37b. After infection was confirmed (or 5 days after challenge virus inoculation), subjects received RV521 (350 mg or 200 mg) or placebo orally every 12 h for 5 days. The primary endpoint was area under the curve (AUC) for viral load, as assessed by reverse transcriptase quantitative PCR (RT-qPCR) of nasal wash samples. The primary efficacy analysis set included subjects successfully infected with RSV who received ≥1 dose of study drug. A total of 66 subjects were enrolled (n = 22 per group); 53 were included in the primary analysis set (RV521 350 mg: n = 16; 200 mg: n = 18; placebo: n = 19). The mean AUC of RT-qPCR-assessed RSV viral load (log10 PFU equivalents [PFUe]/ml · h) was significantly lower with RV521 350 mg (185.26; standard error [SE], 31.17; P = 0.002) and 200 mg (224.35; SE, 37.60; P = 0.007) versus placebo (501.39; SE, 86.57). Disease severity improved with RV521 350 mg and 200 mg versus placebo (P = 0.002 and P = 0.009, respectively, for AUC total symptom score [score × hours]). Daily nasal mucus weight was significantly reduced (P = 0.010 and P = 0.038 for RV521 350 mg and 200 mg, respectively, versus placebo). All treatment-emergent adverse events were grade 1 or 2. No subjects discontinued due to adverse events. There was no evidence of clinically significant viral resistance, and only three variants were detected. RV521 effectively reduced RSV viral load and disease severity in humans and was well tolerated. (This study has been registered at ClinicalTrials.gov under registration no. NCT03258502.).

PURPOSE: The purpose of the study was to evaluate the incidental dose delivered to the internal mammary nodes (IMNs) in patients treated with tangential 3-dimensional conformal radiation therapy and to identify potential parameters that may affect the IMN mean dose. METHODS AND MATERIALS: The study cohort consisted of 362 consecutively treated patients with breast cancer in our center between January 2015 and July 2017 who had received adjuvant whole-breast radiation therapy or postmastectomy radiation with or without a supraclavicular ± axillary field and without intentional inclusion of the IMN chain. The clinical target volume (CTV) for the IMNs was contoured per the Radiation Therapy Oncology Group 3509/3510 protocol and was then divided into 3 subregions: upper, mid, and lower thirds. The planning target volume for the IMNs was generated by adding 5 mm to the CTV. The primary endpoint was to assess the V40 (volume receiving 40 Gy) to the IMN planning target volume and its potential influencing parameters using a linear regression model. RESULTS: The mean (±standard deviation) dose to the CTV IMN chain was 36% ± 28.7%. The Kruskal-Wallis test demonstrated significant differences in the median dose delivered to each level: upper third (7.2%), mid third (21.5%), and lower third (41.7%) (P < .001). The mean V40 IMN planning target volume was 14.2% (standard deviation, 18.7%). Presternal fat thickness (regression coefficient [RC] = -16.4; P < .001), postmastectomy radiation (RC = 24; P < .001), reconstruction after mastectomy (RC = -22.4; P < .001), and the addition of a supraclavicular field (RC = 8.8; P = .03) were all significantly associated with IMN mean dose. CONCLUSIONS: For patients receiving standard breast/chest wall tangential radiation fields, the IMN chain is not incidentally covered with therapeutic doses in the vast majority of cases. Therefore, if regional nodal radiation is intended to include the IMNs, contouring and careful plan review are necessary to ensure adequate therapeutic coverage.

BACKGROUND AND PURPOSE: A lower proportion of CD8+ tumor infiltrating lymphocytes in mycosis fungoides (MF) patients is associated with worse survival. However, it is not known whether circulating CD4:CD8 ratio is a prognosticator of response to total skin electron beam therapy (TSEBT). METHODS AND MATERIALS: We identified 126 MF patients treated with TSEBT from 2001 to 20014 at two high-volume academic centers. Circulating CD4:CD8 ratio was obtained within 1â¯week before TSEBT. TSEBT was delivered with 6-9mEV electrons with low (12â¯Gy) or conventional (≥12â¯Gy) doses. Treatment response was assessed with the modified Severity Weighted Assessment Tool (mSWAT). Post-treatment mSWAT decrease of ≥75% was classified as near complete response (CR) while mSWAT decrease of <75% was considered partial response (PR). Receiver operating characteristic analysis determined an optimal CD4:CD8 threshold value to predict TSEBT response in the derivation cohort and was applied to an external validation cohort. RESULTS: 71.4% and 28.6% of patients achieved CR and PR after TSEBT. Higher CD4:CD8 ratio predicted poorer response: median CD4:CD8 in patients with PR vs. CR was 4.84 vs. 1.97 (pâ¯=â¯0.002). A threshold CD4:CD8 of 4.42 optimally discriminated in the discovery cohort patients with PR vs. XR (sensitivity 90%, specificity 59%, area under curve (AUC)â¯=â¯0.71; pâ¯=â¯0.002). Within an independent test cohort (nâ¯=â¯32), 73.9% of patients with CD4:CD8 <4.42 achieved CR vs. 33.3% of those with CD4:CD8 ≥4.42 (pâ¯=â¯0.033). Among all patients with CD4:CD8 <4.42 (nâ¯=â¯73), 74% achieved CR with low-dose TSEBT vs. 93% with conventional dose TSEBT (pâ¯=â¯0.02). On multivariable logistic regression, CD4:CD8 remained a significant independent predictor of TSEBT response in all patients (ORâ¯=â¯0.107, 95% CI 0.395-0.290, pâ¯<â¯0.001). CONCLUSION: Peripheral blood CD4:CD8 ratio was a significant independent predictor of TSEBT response of MF patients as validated in an independent cohort at separate academic center. The potential for CD4:CD8 ratio as a biomarker to inform radiation treatment dosing warrants further investigation.

PURPOSE: Three-dimensional conformal accelerated partial breast irradiation (APBI) is a treatment option for well selected women with breast cancer, despite reports of adverse cosmetic outcome with this technique. Dose-volume relationships may be responsible for this poor cosmesis. We aimed to determine the feasibility of limiting the exposure of nontarget breast tissue to radiation through smaller planning target volumes achieved through daily image guidance and 4-dimensional computed tomography simulation. METHODS AND MATERIALS: Eligibility criteria included the following: women, age ≥50 years, Karnofsky performance status score ≥70, stage 0 and I breast cancer treated with breast-conserving surgery, margins clear by ≥2 mm, pathologic tumor size ≤2 cm, and 4-dimensional computed tomography with planning target volumes of 0.2 cm rather than the standard 1.0 cm. A dose of 3850 cGy was prescribed in 10 fractions. The study was considered successful if ≥50% of enrollees met dosimetric constraints on the breast (V50 < 45% and V100 < 23.5%). RESULTS: The study achieved its primary endpoint of feasibility of reducing the nontarget breast dose with a breast median of V50 = 31% and V100 = 11%. There were no recurrences and no toxicity grade >3. At baseline, fair/poor cosmesis was low (2.2%). By year 3, adverse cosmesis post-APBI had increased by 13.2% (to 15.4%). Patient decisional satisfaction was reached completely in 84.2% of patients. CONCLUSIONS: This study demonstrated that with 4-dimensional simulated APBI that uses stringent dosimetric constraints and image guidance radiation therapy, it is possible to obtain acceptable cosmetic outcomes. We report no locoregional recurrences in 3 years and no toxicity grade >3. The observed decline in cosmesis was acceptable compared with that of prior published studies, and patient satisfaction with APBI was excellent.

PURPOSE: In an effort to better characterize the extent and impact of residency expansion and job placement, the authors conducted a multilevel survey of radiation oncologists exploring the current state of the radiation oncology employment market. METHODS: A multilevel survey was conducted using the Qualtrics platform in the spring of 2017. Survey participants were categorized into five groups within radiation oncology: (1) chairpersons, (2) program directors, (3) new practitioners (at least 1 year out of residency), (4) new residency graduates (radiation oncology postgraduate year 5 graduates with new jobs), and (5) medical students. The Wilcoxon-Mann-Whitney test was used to compare Likert scale scores. RESULTS: A total of 752 participants were surveyed, with an overall response rate among all five groups of 31% and 92% of those completing the entire survey. Chairpersons were more likely to consider expanding their residency programs compared with program directors. Fellowship remained low on the job search, with less than 10% of new graduates and new practitioners interested in fellowship positions. Job satisfaction was high with 85% of new graduates, and 78% of new practitioners moderately to very satisfied with their future or current employment. The vast majority of both new practitioners (85%) and new graduates (81%) was moderately to very satisfied with their location of practice. CONCLUSIONS: Resident job satisfaction remains high, whereas interest in radiation oncology fellowships remains low. Conflicting perception regarding the job market and residency expansion could have downstream impacts, such as deterring potential applicants.

BACKGROUND AND AIM: Radiotherapy is an effective treatment for cutaneous T-cell lymphoma (CTCL). Since 2009, studies have advocated for low-dose radiotherapy (<30 Gy) given it results in similar response rates and less toxicity compared to higher doses (≥30 Gy). We aimed to see if low-dose radiotherapy has been adopted on a national scale in the USA. MATERIALS AND METHODS: A total of 11,292 adult patients with CTCL were identified in the National Cancer Database. Logistic regression models were created to evaluate predictors for use of low-dose radiotherapy. RESULTS: A minority of patients received low-dose radiotherapy (22.4%). The annual percentage of patients receiving low-dose radiotherapy increased from 17.2% in 2009 to 38.4% in 2015. High-volume facilities were associated with use of low-dose radiotherapy (5th quintile vs. bottom two quintiles, odds ratio(OR)=1.76, 95% confidence interval(CI)=1.22-2.54, p=0.003). CONCLUSION: Although the radiotherapy dose administered is decreasing, most patients with CTCL are still receiving doses that may be higher than needed to palliate their disease effectively.

PURPOSE: To examine the role of radiation oncology (RO) graduates' application patterns and personal preferences in current labor concerns. METHODS AND MATERIALS: An anonymous, voluntary survey was distributed to 665 domestic RO graduates from 2013 to 2017. Questions assessed graduates' regional (Northeast [NE]; Midwest [MW]; South [SO]; West [WT]) job type and population size preferences. Top regional choice was compared across other categorical and numerical variables using the χ2 test and analysis of variance, respectively. RESULTS: Complete responses were obtained from 299 (45.0% response rate) participants: 82 (27.4%), 74 (24.7%), 85 (28.4%), and 58 (19.4%) graduated from NE, MW, SO, and WT programs. The most to least commonly applied regions were SO (69.2%), MW (55.9%), and then NE/WT (55.2% each). The first and last regional choices were the WT (29.4%) and MW (15.7%), respectively. The most and least common application and top choice preferences were consistent in terms of city size: >500,000 (86.0% and 64.5%, respectively) and <100,001 (26.1% and 7.0%, respectively). The majority of applicants applied to both academic and nonacademic positions (60.9%), with top job type choice being equally split. The majority of respondents independently received a job offer in their preferred region (75.3%), city population size (72.6%) or job type (81.9%). Additionally, 52.5% received a job offer that included all three preferences. Those who underwent residency training (44.3% vs 62.0%-83.6%, P < .001) or medical schooling (50.7% vs 56.3%-75.6%, P < .001) or grew up in the MW (60.8% vs 70.0%-74.7%, P < .001) were least likely to choose this region as their top regional choice compared with other regions. CONCLUSIONS: The MW and jobs in smaller cities are less appealing to RO graduates, even if they receive training in the MW, which may contribute to current job market concerns. Nonetheless, the majority of respondents received a job offer in the region, population size, and job type of their top choice. Assessing prospective candidates' city size and geographic preferences and prioritizing applicants who are compatible with positions may help address potential job market discrepancies.

PURPOSE: Beginning in 2010, the ABR has administered triennial clinical practice analysis surveys to inform examination development volunteers and staff about the actual state of radiation oncology practice. METHODS AND MATERIALS: As reported here, the 2016 survey was designed to provide objective data regarding actual patient volumes of specific disease sites and subjective insight as to the importance and relevance of site-specific therapy to individual practices. RESULTS: The survey instrument was circulated to 4,075 radiation oncologists listed in the membership database of the American Society for Radiation Oncology, and responses were received from 690 (16.9%); a total of 287 (41.5%) self-identified as being in academic practice. Even in the academic setting, a majority (216 of 287, or 75.3%) indicated that they spend most of their time in clinical practice. CONCLUSIONS: Data from the survey are informative regarding changes in the practice of radiation oncology over the past 6 years.
