RESUMEN
â¢Stereotactic body radiotherapy (SBRT) is a safe and effective locoregional therapy for inoperable patients with HCC.â¢SBRT compares favorably with other local therapies in terms of local control, survival, morbidity, and cost-effectiveness.â¢SBRT should be considered and discussed in multidisciplinary management of appropriate HCC patients.â¢Advances in SBRT and novel combinations with systemic therapy may further widen the therapeutic index in HCC.
RESUMEN
BACKGROUND AND PURPOSE: Mepitel Film (MF) has been demonstrated to reduce the severity of radiation dermatitis (RD) in patients receiving breast cancer radiotherapy (RT). The objective of this study was to characterize patient-reported experience with MF use, including its impact on daily activities and wellbeing. MATERIALS AND METHODS: This single-institution study analyzed anonymized responses to a questionnaire completed by patients who used MF for the prevention of RD during breast cancer RT. RESULTS: Of the 254 patients contacted, 192 patients completed the survey. Most patients disagreed or strongly disagreed that MF limited their ability to perform their daily activities, including household chores (88%, n = 169/191), their ability to work (83%, n = 157/189), or their ability to sleep (85%, n = 163/191). Furthermore, patients agreed or strongly agreed MF was comfortable on their skin (67%, n = 126/189) and protected their skin from rubbing against clothing (86%, n = 161/188). Some patients agreed or strongly agreed that MF affected their ability to shower (31%, n = 50/162), wear bras (28%, n = 51/185), and impacted their level of pruritus (35%, n = 67/189). However, most patients agreed or strongly agreed that their overall experience with MF was positive (92%, n = 173/189) and would recommend MF to a friend undergoing breast cancer RT (88%, n = 166/188). CONCLUSION: MF use is associated with positive patient-reported experience during breast RT with minimal impact on daily activities.

We explored perspectives of patients with metastatic non-small cell lung cancer (mNSCLC) on symptom screening and population-level patient-reported outcome (PRO) data regarding common symptom trajectories in the year after diagnosis. A qualitative study of patients with mNSCLC was conducted at a Canadian tertiary cancer centre. English-speaking patients diagnosed ≥ 6 months prior to study invitation were recruited, and semi-structured one-on-one interviews were conducted. Patient and treatment characteristics were obtained via chart review. Anonymized interview transcripts underwent deductive-inductive coding and thematic content analysis. Among ten participants (5 (50%) females; median (range) age, 68 (56-77) years; median (range) time since diagnosis, 28.5 (6-72) months; 6 (60%) with smoking histories), six themes were identified in total. Two themes were identified regarding symptom screening: (1) screening is useful for symptom self-monitoring and disclosure to the healthcare team, (2) screening of additional quality-of-life (QOL) domains (smoking-related stigma, sexual dysfunction, and financial toxicity) is desired. Four themes were identified regarding population-level symptom trajectory PRO data: (1) data provide reassurance and motivation to engage in symptom self-management, (2) data should be disclosed after an oncologic treatment plan is developed, (3) data should be communicated via in-person discussion with accompanying patient-education resources, and (4) communication of data should include reassurance about symptom stabilization, acknowledgement of variability in patient experience, and strategies for symptom self-management. The themes and recommendations derived from the patient experience with mNSCLC provide guidance for enhanced symptom screening and utilization of population-level symptom trajectory data for patient education.

INTRODUCTION: Randomized clinical trials support Mepitel Film (MF) as a prophylactic treatment for radiation dermatitis (RD) in patients undergoing breast radiotherapy. Although several studies have canvassed the opinion of patients on using MF, no such studies have been done to investigate the perception of healthcare professionals (HCPs). The objective of this study was therefore to investigate the perceptions of HCPs on MF as a treatment option for RD. METHODS: Anonymized responses to a web-based survey sent to HCPs at a single institution managing patients using MF during breast radiotherapy were analyzed. RESULTS: Of the 28 HCPs contacted, 22 completed the survey, including 6 radiation oncologists (ROs), 11 radiation therapists (RTTs), and 5 nurses. Most HCPs reported MF was better at preventing severe RD than the standard of care and improved radiation-induced skin reactions (n = 20/22, 91%, and n = 19/22, 86%, respectively). MF was recommended for mastectomy patients without reconstruction (n = 15/21, 71%). The majority of HCPs believed that patients' families could be trained to apply and remove MF (n = 19/22, 86%). Many HCPs perceived that implementation of MF would be difficult in terms of maintaining patient flow and wide-scale implementation within their institution (n = 11/22, 50%, and n = 10/22, 46%, respectively). Most HCPs perceived that fewer than 50% of their patients could afford MF if priced at $100 CAD (n = 15/20, 75%). CONCLUSION: These findings provide insights into the possibility of MF to be incorporated into standard practice of care for RD. Although most HCPs were satisfied with MF as a prophylactic treatment for RD, there are concerns about its resource-intensive operationalization and financial accessibility to patients. Future research should focus on ways to improve HCP experience with MF and to improve its implementation into clinical settings as standard of care.

Radiotherapy is a mainstay treatment option for localized prostate cancer (PCa), with oncological outcomes similar to those with surgery. Standard-of-care radiotherapy approaches include brachytherapy, hypofractionated external beam radiotherapy (EBRT), and EBRT with brachytherapy boost. Given the long survival associated with PCa and these curative-intent radiotherapy approaches, late toxicity is a paramount consideration. In this narrative mini-review, we summarize late toxicities associated with standard-of-care radiotherapy approaches including stereotactic body radiotherapy, an advanced radiotherapy technique supported by accumulating evidence. We also discuss stereotactic magnetic resonance imaging-guided adaptive radiotherapy (SMART), an emerging paradigm that may further improve the therapeutic index of radiotherapy and reduce late toxicities. PATIENT SUMMARY: This mini-review summarizes late side effects associated with standard and advanced radiotherapy techniques for localized prostate cancer. We also discuss a new radiotherapy approach called SMART that may reduce late side effects and increase treatment effectiveness.

Purpose: This study aimed to characterize contemporary management of Canadian patients with cardiovascular implantable electronic devices (CIEDs) undergoing radiation therapy (RT) in light of updated American Association of Physicists in Medicine guidelines. Methods and Materials: A 22-question web-based survey was distributed to members of the Canadian Association of Radiation Oncology, Canadian Organization of Medical Physicists, and Canadian Association of Medical Radiation Technologists from January to February 2020. Respondent demographics, knowledge, and management practices were elicited. Statistical comparisons by respondent demographics were performed using χ2 and Fisher exact tests. Results: In total, 155 surveys were completed by 54 radiation oncologists, 26 medical physicists, and 75 radiation therapists in academic (51%) and community (49%) practices across all provinces. The majority of respondents (77%) had managed >10 patients with CIEDs in their career. Most respondents (70%) reported using risk-stratified institutional management protocols. Respondents used manufacturer recommendations, rather than American Association of Physicists in Medicine or institutionally recommended dose limits, when the manufacturer limit was 0 Gy (44%), 0 to 2 Gy (45%), or >2 Gy (34%). The majority of respondents (86%) reported institutional policies to refer to a cardiologist for CIED evaluation both before and after completion of RT. Cumulative dose to CIED, pacing dependence, and neutron production were considered during risk stratification by 86%, 74%, and 50% of participants, respectively. Dose and energy thresholds for high-risk management were not known by 45% and 52% of respondents, with radiation oncologists and radiation therapists significantly less likely to report thresholds than medical physicists (P < .001). Although 59% of respondents felt comfortable managing patients with CIEDs, community respondents were less likely to feel comfortable than academic respondents (P = .037). Conclusions: The management of Canadian patients with CIEDs undergoing RT is characterized by variability and uncertainty. National consensus guidelines may have a role in improving provider knowledge and confidence in caring for this growing population.

Canadian radiation oncology (RO) residency programs transitioned to a competency-based medical education (CBME) training model named Competence by Design (CBD) in July 2019. Prior to this, CBD was piloted in a single RO training program to characterize assessment completion and challenges of implementation. Six residents and seven staff participated in a mixed-methods study and were oriented to CBD. Four Entrustable Professional Activities were assessed over a 4-week-long block and documented using online assessment forms. Anonymized assessments were analyzed to characterize completion. Post-pilot surveys were completed by 4/6 residents and 5/7 staff. Semi-structured post-pilot focus groups were conducted with all residents. Assessments were requested and documented on a weekly basis. Narrative comments were found in 68.1% of assessments, of which 26.7% described specific examples of observed competence or recommendations for improvement. Three of five staff believed that assessments have a negative impact on clinical workflow. Three themes were identified: (1) direct observation is the most challenging aspect of CBD to implement; (2) feedback content can be improved; and (3) staff attitude, clinical workflow, and inaccessibility of assessment forms are the primary barriers to completing assessments. This study demonstrates that CBD assessments can be completed regularly in an outpatient radiation oncology setting and that implementation challenges include improving feedback quality, promoting direct observation, and continuing faculty development to improve perceptions of this assessment model. Further study is required to identify best practices and expectations for the discipline in the era of CBME.

BACKGROUND: Virtual care (VC) visits (telephone or video) and email-based patient communication have been rapidly adopted to facilitate cancer care during the COVID-19 pandemic. Inequities in access and patient experience may arise as these digital health tools become prevalent. OBJECTIVE: We aimed to characterize inequities in access and patient-reported experience following adoption of digital health tools at a tertiary cancer center during the COVID-19 pandemic. METHODS: We designed a cross-sectional study of outpatients with visits from September to December 2020. Patient characteristics and responses to an email-based patient-experience survey were collated. Inequities in access were assessed across three pairs of comparison groups: (1) patients with VC and in-person visits, (2) patients with and without documented email addresses, and (3) responders and nonresponders to the survey. Inequities in patient-reported experience were assessed among survey responders. Demographics were mapped to area-level averages from national census data. Socioeconomic status was mapped to area-level dimensions of the Canadian Index of Multiple Deprivation. Covariate balance between comparison groups was assessed using standardized mean differences (SMDs), with SMD≥0.2 indicating differences between groups. Associations between patient experience satisfaction scores and covariates were assessed using multivariable analyses, with P<.05 indicating statistical significance. RESULTS: Among the 42,194 patients who had outpatient visits, 62.65% (n=26,435) had at least one VC visit and 31.15% (n=13,144) were emailable. Access to VC and email was similar across demographic and socioeconomic indices (SMD<0.2). Among emailable patients, 21.84% (2870/13,144) responded to the survey. Survey responsiveness was similar across indices, aside from a small difference by age (SMD=0.24). Among responders, 24.4% received VC and were similar to in-person responders across indices (SMD<0.2). VC and in-person responders had similar satisfaction levels with all care domains surveyed (all P>.05). Regardless of visit type, patients had variable satisfaction with care domains across demographic and socioeconomic indices. Patients with higher ethnocultural composition scores were less satisfied with the cultural appropriateness of their care (odds ratio [OR] 0.70, 95% CI 0.57-0.86). Patients with higher situational vulnerability scores were less satisfied with discussion of physical symptoms (OR 0.67, 95% CI 0.48-0.93). Patients with higher residential instability scores were less satisfied with discussion of both physical (OR 0.81, 95% CI 0.68-0.97) and emotional (OR 0.86, 95% CI 0.77-0.96) symptoms, and also with the duration of their visit (OR 0.85, 95% CI 0.74-0.98; P=.02). Male patients were more satisfied with how their health care provider had listened to them (OR 1.64, 95% CI 1.11-2.44; P=.01). CONCLUSIONS: Adoption of VC and email can equitably maintain access and patient-reported experience in cancer care across demographics and socioeconomic indices. Existing health inequities among structurally marginalized patients must continue to be addressed to improve their care experience.

Feedback delivery and training have not been characterized in the context of academic cancer centres. The purpose of this study was to assess the feasibility and utility of a microlearning course based on the R2C2 (Relationship, Reaction, Content, Coaching) feedback model and characterize multidisciplinary healthcare provider (HCP) perspectives on existing feedback practices in an academic cancer centre. Five HCP (two radiation oncologists, one medical oncologist, and two allied health professionals) with supervisory roles were selected by purposive sampling to participate in a prospective longitudinal qualitative study. Each participant completed a web-based multimedia course. Semi-structured one-on-one interviews were conducted with each participant at four time points: pre- and immediately post-course, and at one- and three-months post course. All participants found the course to be time feasible and completed it in 10-20 min. Participants expressed that the course fulfilled their need for feedback training and that its adoption may normalize a feedback culture in the cancer centre. Three themes were identified regarding perceptions of existing feedback practices: (1) hierarchical and interdisciplinary relationships modulate feedback delivery, (2) interest in feedback delivery varies by duration of the supervisory relationship, and (3) the transactionality of supervisor-trainee relationships influences feedback delivery. This study demonstrates the perceived feasibility and utility of a digital microlearning approach for development of feedback competencies in an academic cancer centre, perceptions of cultural barriers to feedback delivery, and the need for organizational commitment to developing a feedback culture.

OBJECTIVES: Stereotactic ablative radiotherapy (SABR) is used to treat inoperable early-stage, node-negative small cell lung cancer (SCLC). We performed a systematic review and meta-analysis of the literature on SABR for T1-2N0M0 SCLC to summarize outcomes including local control (LC), overall survival (OS), recurrence rates, and toxicity. MATERIALS AND METHODS: This study was conducted in accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) and MOOSE (Meta-analysis of Observational Studies in Epidemiology) guidelines. A systematic review of PubMed and EMBASE (inception to April 2021) was conducted. Two authors independently reviewed articles for inclusion and extracted study-level data. Random-effects meta-analysis was conducted using R (version 3.6.2) at a significance threshold of 0.05. RESULTS: Eleven studies were identified in the systematic review and seven (399 patients) were selected for meta-analysis. Inoperability was noted as the indication for SABR in 94% (75-100%) of patients. Median follow-up and tumor size were 19.5 months (11.9-32) and 24 mm (19-29), respectively. Chemotherapy and PCI use rates were 44.1% (95% confidence interval [CI], 27.0-61.9%) and 13.8% (95% CI, 0.4-41.2%), respectively. Local control was 97.3% (95% CI, 92.3-99.8%) at 1 year and 95.7% (95% CI, 74.2-100.0%) at 2 years. Overall survival was 86.3% (95% CI, 74.4-94.9%) at 1 year and 63.7% (95% CI, 45.7-79.9%) at 2 years. Nodal and distant recurrence rates were 17.8% (95% CI, 7.5-31.2%) and 26.9% (95% CI, 7.4-53.0%), respectively. The rates of grade 1, grade 2, and grade 3 toxicity (CTCAE) were 12.6% (95% CI, 6.7-19.9%), 6.7% (95% CI, 3.3-11.2%), and 1.4% (95% CI, 0.0-5.3%), respectively. No grade 4 or 5 events were observed across the studies. CONCLUSION: SABR for inoperable early-stage, node-negative SCLC is locally effective with limited toxicity. Prospective studies are required to further evaluate the role of SABR for patients at higher risk of toxicity with surgery or combined chemoradiation.

Introduction Many undergraduate medical education (UME) programs have begun adopting point-of-care ultrasound (PoCUS) curricula, reflecting the increasing ubiquity of this technique across medical specialties. The structures of international PoCUS curricula have been extensively studied. However, the efficacy of these curricula to increase knowledge and confidence in PoCUS is less well-studied. We investigated whether a structured, small-group PoCUS teaching session consisting of pre-defined learning objectives, an introductory presentation, and a mandatory hands-on scanning component would increase pre-clerk knowledge of and confidence in PoCUS theory, use, and interpretation. Methods A pre-post study was designed to assess changes in pre-clerk knowledge and confidence in PoCUS theory, use, and interpretation. Pre-clerks were recruited from the Hamilton campus of the Michael G. DeGroote School of Medicine at McMaster University. Pre-clerks were organized into four groups, with an average group size of seven learners. Two preceptors each taught two groups. Sessions included an introductory PowerPoint presentation and one-on-one preceptor-guided practice in identifying abdominal and genitourinary structures using PoCUS. Student responses on pre- and post-intervention surveys were analyzed to identify changes in knowledge and confidence. Student satisfaction with the teaching session was assessed from self-reported levels of agreement with satisfaction statements. The strengths and areas of improvement for the teaching sessions were identified from open-ended survey responses. Results Data from 27 students indicated a significant improvement in knowledge test scores (p < .05), with no significant differences between groups (F(3,23) = 0.64, p = n.s.) or between students with different preceptors (p = n.s.). Students' confidence in PoCUS use and interpretation improved significantly (p < .05 for both), with no significant differences between groups (F(3,23) = 0.70, p = n.s. and F(3,23) = 0.32, p = n.s., respectively) or between students with different preceptors (p = n.s. for both). Improvements in knowledge of and confidence in PoCUS use were significantly correlated (r = .44, p < .05). All of the students agreed that they liked the instruction, content, and structure of the teaching session. The most frequently cited strengths of the teaching sessions were the mandatory individual practice time per student, individualized instruction from and interactions with preceptors, and the small group structure of the sessions. Conclusion This study provides novel evidence that a structured, small-group teaching session featuring a didactic presentation, defined learning objectives, and mandatory hands-on learning can effectively teach introductory PoCUS knowledge and skills to pre-clerks and increase student confidence. Future studies will investigate the retention and application of PoCUS knowledge and skill throughout clerkship and early residency training to determine if this teaching model can facilitate longitudinal PoCUS learning and competency as well as improved diagnostic capabilities as students advance through undergraduate medical training.
