ABSTRACT

Background: Delays in starting postoperative radiotherapy (PORT) have been established as negative predictors for clinical outcomes in head and neck squamous cell carcinomas (HNSCC). Our study aimed to examine the effect of delays during PORT, and the impact of national holidays in Canada, a publicly funded system, on oncologic outcomes such as Overall Survival (OS) and Local Recurrence (LR). Methods: The provincial cancer registry was queried to obtain demographic, pathologic, and outcomes data from cancer patients treated for all squamous cell carcinomas of the head and neck region treated between January 1, 2007 and November 30, 2019. All extracted information was cross-referenced and supplemented by chart review of patient electronic medical records. Extracted data were analyzed for OS and LR, in the context of Canadian national holidays causing delays during PORT. Results: 1433 patients treated for HNSCCs were identified, of whom 338 were treated curatively with surgery followed by PORT. 68.6% of patients experienced at least one day of interruption during treatments due to holidays. LR was 15.4% and OS was 59.6% at 5 years. Treatment interruptions by holidays were predictive of local recurrence (HR, 2.38; 95% CI 1.17-4.83; p = 0.017). Patients that developed early recurrence prior to PORT had very poor oncologic outcomes. Conclusion: Our findings were consistent with previously published studies in limiting the interval between surgery and PORT. We identified the novel finding of paired holidays as a significant predictor in determining LR, suggesting the importance of modifying RT delivery schedules and timing.

ABSTRACT

PURPOSE: The ongoing lack of data standardization severely undermines the potential for automated learning from the vast amount of information routinely archived in electronic health records (EHRs), radiation oncology information systems, treatment planning systems, and other cancer care and outcomes databases. We sought to create a standardized ontology for clinical data, social determinants of health, and other radiation oncology concepts and interrelationships. METHODS AND MATERIALS: The American Association of Physicists in Medicine's Big Data Science Committee was initiated in July 2019 to explore common ground from the stakeholders' collective experience of issues that typically compromise the formation of large inter- and intra-institutional databases from EHRs. The Big Data Science Committee adopted an iterative, cyclical approach to engaging stakeholders beyond its membership to optimize the integration of diverse perspectives from the community. RESULTS: We developed the Operational Ontology for Oncology (O3), which identified 42 key elements, 359 attributes, 144 value sets, and 155 relationships ranked in relative importance of clinical significance, likelihood of availability in EHRs, and the ability to modify routine clinical processes to permit aggregation. Recommendations are provided for best use and development of the O3 to 4 constituencies: device manufacturers, centers of clinical care, researchers, and professional societies. CONCLUSIONS: O3 is designed to extend and interoperate with existing global infrastructure and data science standards. The implementation of these recommendations will lower the barriers for aggregation of information that could be used to create large, representative, findable, accessible, interoperable, and reusable data sets to support the scientific objectives of grant programs. The construction of comprehensive "real-world" data sets and application of advanced analytical techniques, including artificial intelligence, holds the potential to revolutionize patient management and improve outcomes by leveraging increased access to information derived from larger, more representative data sets.

ABSTRACT

Purpose: Outside of randomized clinical trials, it is difficult to develop clinically relevant evidence-based recommendations for radiation therapy (RT) practice guidelines owing to lack of comprehensive real-world data. To address this knowledge gap, we formed the Learning from Analysis of Multicenter Big Data Aggregation consortium to cooperatively implement RT data standardization, develop software solutions for data analysis, and recommend clinical practice change based on real-world data analyzed. The first phase of this "Big Data" study aimed at characterizing variability in clinical practice patterns of dosimetric data for organs at risk (OARs) that would undermine subsequent use of large-scale, electronically aggregated data to characterize associations with outcomes. Evidence from this study was used as the basis for practical recommendations to improve data quality. Methods and Materials: Dosimetric details of patients with head and neck cancer treated with radiation therapy between 2014 and 2019 were analyzed. Institutional patterns of practice were characterized, including structure nomenclature, volumes, and frequency of contouring. Dose volume histogram (DVH) distributions were characterized and compared with institutional constraints and literature values. Results: Plans for 4664 patients treated to a mean plan dose of 64.4 ± 13.2 Gy in 32 ± 4 fractions were aggregated. Before implementation of TG-263 guidelines in each institution, there was variability in OAR nomenclature across institutions and structures. With evidence from this study, we identified a targeted and practical set of recommendations aimed at improving the quality of real-world data. Conclusions: Quantifying similarities and differences among institutions for OAR structures and DVH metrics is the launching point for next steps to investigate potential relationships between DVH parameters and patient outcomes.

ABSTRACT

Despite the known importance and necessity of the standardized collection and use of patient-reported outcomes (PROs), there remain challenges to successful clinical implementation. Facilitated through a quality improvement initiative spearheaded by the Canadian Partnership for Quality Radiotherapy (CPQR), and now guided by the Canadian Association of Radiation Oncology (CARO)'s Quality and Standards Committee, patient representatives and early-adopter radiation treatment programs continue to champion the expansion of PROs initiatives across the country. The current review discusses the evolution of a pan-Canadian approach to PROs use, striving to fill in gaps between clinical practice and guideline recommendations through multi-centre and multidisciplinary collaboration.

ABSTRACT

Patient engagement and education have been mandated across Canadian radiation oncology programs (ROP). Guidance documents include the 2014 Canadian Association of Radiation Oncology (CARO) Radiation Therapy Patient Charter, the 2016 Canadian Partnership for Quality Radiotherapy (CPQR) Patient Engagement Guidelines (PEG) for Canadian Radiation Treatment Programs, and Accreditation Canada's 2017 refresh of Cancer Care Standards. Since little is known regarding uptake of these guidance statements, Canadian ROP were surveyed to assess current patient engagement and education practices. An e-survey was sent to Canadian ROP (n = 44). The survey focused on awareness and uptake of the CARO Patient Charter, CPQR PEG, and patient education practices. Survey development was guided by these documents and expert consensus, including CARO's Quality and Standards Patient Education/Engagement working group. Many (71%) responding ROP were familiar with the CARO Patient Charter, while 24% reported use. More than half (53%) of ROP were aware of the CPQR PEG, but approximately third (37%) had previously completed a self-audit. Most (88%) ROP view a pan-Canadian, evidence-based approach to educational materials beneficial and feasible (80%), with the majority (89%) willing to share their best practices across the radiotherapy community. Patient engagement and education are nationally mandated and supported by guidance documents. However, gaps have been identified across ROP for awareness and use of available tools, as well as uptake of their processes critical to quality of care. Understanding current practices will inform CPQR/CARO-supported pan-Canadian initiatives to optimize uptake, including development of CPQR Patient Education Guidance for Canadian Radiation Treatment Programs.

ABSTRACT

Cancer is the leading cause of mortality in Canada. Undergraduate medical education therefore must ensure adequate oncology education for all physicians and inspire some to make oncology their career specialty, in an effort to ensure public care needs are met in the future. Medical student-led oncology interest groups (OIGs) are a subset of specialty interest groups that supplement formal didactic and clinical learning to increase exposure to oncology and access to mentors. We conducted a survey of OIG leaders to ascertain their goals, activities, barriers, future directions, and perceptions about employment prospects. OIG leaders from 12/17 Canadian medical schools responded. Medical oncology was the most represented specialty in OIGs. Half of OIGs had faculty mentors. Self-reported goals were to increase exposure to oncology disciplines (n = 12), assist students with career selection (n = 11) and finding mentors (n = 7), and enhance oncology education (n = 10). OIGs held on average 5 events per year (range 1-12). Reported barriers were finding time to plan events, declining student interest over academic year, and limited funding. Many OIGs showed interest in more standardized resources about oncology disciplines (n = 9), access to presentations (n = 10), more funding (n = 7), and collaboration (n = 7). Employment in many oncology specialties was perceived poorly, and the most important career selection considerations were ease of employment, practice location, and partner/family preference. Our survey highlights common goals, barriers, and perceptions in OIG medical student leaders across Canada and provides guidance for future interventions.

ABSTRACT

PURPOSE: The impact that early clinical exposure to radiation oncology has on medical students' understanding of oncology and career choice is understudied. This study aims to review the experience and outcomes of medical students who participated in the Canadian Association of Radiation Oncology-Canadian Radiation Oncology Foundation 6-week summer studentship. METHODS AND MATERIALS: Medical students who participated in the nationally funded studentship from 2014 to 2018 were asked to fill out a survey after completing the program. The survey asked about student experience related to radiation oncology before the studentship, student satisfaction with the studentship (scale of 1-5; 5 = outstanding, 3 = meets expectations, 1 = unsatisfactory), and student willingness to recommend it to other students (scale of 1-10; 1 = strongly disagree, 5 = neutral, 10 = strongly agree). The effect of studentship on interest in the specialty was assessed (scale of 1-10; 1 = strongly disagree, 5 = neutral, 10 = strongly agree), including intent to direct their career toward radiation oncology. Match rates to radiation oncology residency are reported for students who participated in the studentship from 2013 to 2016. RESULTS: All 31 students responded to the survey. Overall, the program was highly rated: inclusion of a broad range of clinical problems (mean = 4.6/5); opportunity to learn assessment, investigation, and management (mean = 4.2/5); and overall educational value (mean = 4.8/5). Poststudentship, most students reported an increased interest in oncology (76%, n = 22/29), and specifically radiation oncology (83%, n = 24/29). They would highly recommend this program to another medical student (mean = 9.8/10). The average percentage of these students entering a radiation oncology career (30.5%) each year was higher than national residency match rates in radiation oncology (0.7%). CONCLUSIONS: Clinical exposure to radiation oncology through a nationally funded Canadian Association of Radiation Oncology-Canadian Radiation Oncology Foundation summer studentship positively affected medical student interest in oncology. This study suggests a potential effect of the studentship program on career selection of radiation oncology.

ABSTRACT

This study describes a medical school oncology interest group (OIG) and assesses its influence on student perceptions of oncology, interest in pursuing oncology as a career, and comfort levels with oncology topics such as breaking bad news. From 2015 to 2017, the OIG annual event took place at a satellite campus of a larger Canadian undergraduate medical school. The event provided a question and answer period with a panel of physicians from multiple oncology specialties-discussions focused around lifestyle, training, clinical work, lifestyle, and career focus. Small physician-led groups taught breaking bad news using the SPIKES framework. The interest group also provided a mentoring and networking opportunity to interested students. Pre- and post-event surveys were distributed to students and physicians. For three consecutive years, the student-run, and physician-mentored OIG successfully recruited student and physician participants, providing a clinical skill teaching session as well as mentorship opportunities to students. Pre-event surveys found that only 20% of students believed their current curriculum was adequate as it relates to oncology education. In pre-session, 13% (6/45) of students indicated comfort with the skill of breaking bad news, compared with that in post-session with 81% (34/42) of students feeling comfortable. When asked "How likely are you to pursue a future elective opportunity in oncology?" 49% (20/41) of students indicated "likely" as their response in the pre-session. This response increased post-session to 70% (28/40). The event highlighted the potential for OIGs to increase student interest in pursuing oncology electives and student-perceived comfort with breaking bad news. OIGs are important in promoting interest in the field of oncology and in improving confidence in breaking bad news. This medical student-created, run and maintained oncology interest group supplemented standard curriculum by providing relevant educational and mentorship opportunities to students. This study highlights the feasibility of implementing a self-sustaining medical school oncology interest group and its potential to positively impact student learning and interest in oncology.

ABSTRACT

It is an exciting time for big data efforts in radiation oncology. The use of big data to help aid both outcomes and decision-making research is becoming a reality. However, there are true challenges that exist in the space of gathering and utilizing performance and outcomes data. Here, we summarize the current state of big data in radiation oncology with respect to outcomes and discuss some of the efforts and challenges in radiation oncology big data.

ABSTRACT

Standardized collection and use of clinical patient-reported outcomes (PRO) have potential to benefit the care of individual patients and improve radiotherapy system performance. Its centralized health-care system makes Canada a prime candidate to take a leader and collaborator role in international endeavors to promote expansion of patient-reported outcome collection and use in radiotherapy. The current review discusses the development of a pan-Canadian approach to PRO use, through a quality improvement initiative led by the Canadian Partnership for Quality Radiotherapy (CPQR), a unique partnership of Canadian radiotherapy professional organizations (Canadian Association of Radiation Oncology-CARO, Canadian Organization of Medical Physicists-COMP, and the Canadian Association of Medical Radiation Technologists-CAMRT).

ABSTRACT

PURPOSE: To develop an entry-to-practice quality and safety competency profile for radiation oncology residency. METHODS AND MATERIALS: A comprehensive list of potential quality and safety competency items was generated from public and professional resources and interprofessional focus groups. Redundant or out-of-scope items were eliminated through investigator consensus. Remaining items were subjected to an international 2-round modified Delphi process involving experts in radiation oncology, radiation therapy, and medical physics. During Round 1, each item was scored independently on a 9-point Likert scale indicating appropriateness for inclusion in the competency profile. Items indistinctly ranked for inclusion or exclusion were re-evaluated through web conference discussion and reranked in Round 2. RESULTS: An initial 1211 items were compiled from 32 international sources and distilled to 105 unique potential quality and safety competency items. Fifteen of the 50 invited experts participated in round 1: 10 radiation oncologists, 4 radiation therapists, and 1 medical physicist from 13 centers in 5 countries. Round 1 rankings resulted in 80 items included, 1 item excluded, and 24 items indeterminate. Two areas emerged more prominently within the latter group: change management and human factors. Web conference with 5 participants resulted in 9 of these 24 items edited for content or clarity. In Round 2, 12 participants rescored all indeterminate items resulting in 10 items ranked for inclusion. The final 90 enabling competency items were organized into thematic groups consisting of 18 key competencies under headings adapted from Deming's System of Profound Knowledge. CONCLUSIONS: This quality and safety competency profile may inform minimum training standards for radiation oncology residency programs.

ABSTRACT

PURPOSE: Peer review (PR) of treatment plans has been recognized internationally as a key component of quality care in radiation oncology programs (ROPs). We conducted a survey of Canadian ROPs to describe current PR practices and identify barriers/facilitators to PR optimization. METHODS AND MATERIALS: A 42-item e-survey was sent to all Canadian ROPs (n = 44). Survey development was guided by expert consensus, literature review, and existing guidelines. One multidisciplinary response per ROP was requested. RESULTS: Response rate was 100.0% (44/44). All ROPs (100.0%) reported conducting some PR and rated its importance as 7/10 or higher (10 = extremely important). One-half of ROPs (52.3%) peer-reviewed >80% of curative treatment plans. ROPs reported performing PR "always/almost always" pretreatment (38.6%) or before 25% of radiation therapy delivery (52.3%). The majority of ROPs reported recommending major plan changes in <5% of plans (88.6%) and documenting findings in the medical record (58.1%). Barriers to PR were radiation oncologist availability (34.1%) and time constraints (27.3%). Facilitators included development of PR standards (97.7%) and education/support (90.9%). CONCLUSIONS: The ROPs perceive PR as highly important, but substantial variation in the extent, timing, and documentation of PR exists. The understanding of current PR activities, barriers, and facilitators will inform the development of initiatives to optimize PR in radiation oncology.

ABSTRACT

PURPOSE: Guidelines recommend documentation of care preferences for patients with advanced cancer upon hospital admission.We assessed end-of-life outcomes for patients who did or did not have code status (CS) documented within 48 h of admission. METHODS: This was a retrospective cohort study of patients who died on an inpatient oncology ward between January 2004 and February 2009. Primary end-of-life outcomes were "code blues" and cardiopulmonary resuscitation (CPR) attempts; secondary outcomes included unsuccessful CPR attempts, intensive care unit (ICU), consultations, and ICU admissions. Using logistic regression, outcomes were compared between those with and without CS documentation ≤ 48 h from admission (full code or do-not-resuscitate), controlling for significant confounders. RESULTS: The 336 patients had a median age of 61 years; 97 % had advanced cancer. The median time from admission to death was 12 days (range <1-197 days); 151 patients (45 %) had CS documentation ≤ 48 h from admission. Controlling for confounders of reason for admission and marital status, patients with CS documentation ≤ 48 h from admission had fewer "code blues" (2 vs. 15 %; adjusted odds ratio(AOR) 0.12, 95% confidence interval (CI) 0.02-0.43), CPR attempts (1 vs. 11 %; AOR 0.12, 95 % CI 0.01-0.51), unsuccessful CPR attempts (0 vs. 11 %), ICU consultations (9 vs. 30 %; AOR 0.19, 95 % CI 0.08-0.40) and ICU admissions (2 vs. 5 %; AOR 0.18, 95 %CI 0.02-0.85). CONCLUSIONS: In patients who died on an oncology ward, CS documentation within 48 h of admission was associated with less aggressive end-of-life care, regardless of the reason for admission.

ABSTRACT

We have discovered that ultrasound-mediated microbubble vascular disruption can enhance tumor responses to radiation in vivo. We demonstrate this effect using a human PC3 prostate cancer xenograft model. Results indicate a synergistic effect in vivo with combined single treatments of ultrasound-stimulated microbubble vascular perturbation and radiation inducing an over 10-fold greater cell kill with combined treatments. We further demonstrate with experiments in vivo that induction of ceramide-related endothelial cell apoptosis, leading to vascular disruption, is a causative mechanism. In vivo experiments with ultrasound and bubbles permit radiation doses to be decreased significantly for comparable effect. We envisage this unique combined ultrasound-based vascular perturbation and radiation treatment method being used to enhance the effects of radiation in a tumor, leading to greater tumor eradication.

ABSTRACT

PURPOSE: Symptom control and improved quality of life (QOL) are primary goals of treatment in palliative oncology. The present study assessed and compared patient demographics, baseline Karnofsky Performance Status (KPS) and QOL using the QLQ-C15-PAL questionnaire prior to palliative radiotherapy (RT) for bone, brain, or lung disease. Few studies have used this questionnaire, an abbreviated version that was developed by the European Organization for Research and Treatment of Cancer specifically for patients with advanced cancer to decrease the burden of completing the longer, more time-consuming QLQ-C30. METHODS: Patients referred to an outpatient palliative RT clinic completed QLQ-C15-PAL questionnaires prior to palliative RT for bone, brain, or lung cancer sites. The associations between baseline QLQ-C15-PAL functional/symptom scales, patient demographics, and clinical variables including KPS were explored. RESULTS: When data from all 369 patients were analyzed, higher KPS scores correlated significantly with better overall QOL and higher physical and emotional functioning. The QLQ-C15-PAL provided more detailed information regarding how symptom burden varied depending on disease site. Patients with bone metastases had worse QLQ-C15-PAL scores for pain, while those with brain and lung disease had worse scores for fatigue. Other health-related QOL scores measured by the QLQ-C15-PAL varied as a function of age and gender. CONCLUSION: As the QLQ-C15-PAL provides detailed and often critical information regarding symptom burden, it may eventually be recognized as a universal core questionnaire to assess QOL in this patient population with advanced cancer while relieving the survey burden.

ABSTRACT

PURPOSE: The 20-item European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Brain Neoplasm (QLQ-BN20) is a validated quality-of-life (QOL) questionnaire for patients with primary brain tumors. The European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core 15 Palliative (QLQ-C15-PAL) core palliative questionnaire is a 15-item version of the core 30-item QLQ-C30 and was developed to decrease the burden on patients with advanced cancer. The combination of the QLQ-BN20 and QLQ-C30 to assess QOL may be too burdensome for patients. The primary aim of this study was to assess QOL in patients before and after treatment for brain metastases using the QLQ-BN20+2 and QLQ-C15-PAL, a version of the QLQ-BN20 questionnaire with 2 additional questions assessing cognitive functioning that were not addressed in the QLQ-C15-PAL. METHODS AND MATERIALS: Patients with brain metastases completed the QLQ-C15-PAL and QLQ-BN20+2 questionnaires to assess QOL before and 1 month after radiation. Linear regression analysis was used to assess changes in QOL scores over time, as well as to explore associations between the QLQ-BN20+2 and QLQ-C15-PAL scales, patient demographics, and clinical variables. Spearman correlation assessed associations between the QLQ-BN20+2 and QLQ-C15-PAL scales. RESULTS: Among 108 patients, the majority (55%) received whole-brain radiotherapy only, with 65% of patients completing follow-up at 1 month after treatment. The most prominent symptoms at baseline were future uncertainty (QLQ-BN20+2) and fatigue (QLQ-C15-PAL). After treatment, significant improvement was seen for the QLQ-C15-PAL insomnia scale, as well as the QLQ-BN20+2 scales of future uncertainty, visual disorder, and concentration difficulty. Baseline Karnofsky Performance Status was negatively correlated to QLQ-BN20+2 motor dysfunction but positively related to QLQ-C15-PAL physical functioning and QLQ-BN20+2 cognitive functioning at baseline and follow-up. QLQ-BN20+2 scales of future uncertainty and motor dysfunction correlated with the most QLQ-C15-PAL scales, including overall QOL (negative association) at baseline and follow-up. CONCLUSION: After radiation, the questionnaires showed maintenance of QOL and improvement of QOL scores such as future uncertainty, which featured prominently in this patient population. It is proposed that the 37-item QLQ-BN20+2 and QLQ-C15-PAL, as opposed to the 50-item QLQ-BN20 and QLQ-C30, may be used together as a universal QOL assessment tool in this setting.

ABSTRACT

PURPOSE: The purpose of this study is to compare self-reported quality of life (QOL) scores in old and young patients with metastatic cancer using the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C15-PAL questionnaire. MATERIALS AND METHODS: Patients receiving palliative radiotherapy (RT) for bone metastases and brain metastases completed the QLQ-C15-PAL questionnaire prior to treatment. Using multiple linear regression analysis, a parametric test, the QLQ-C15-PAL scores were compared using 65 and 70 years as cutoff ages. RESULTS: A total of 340 patients were referred for palliative RT for bone metastases (n = 190) or brain metastases (n = 150). Physical functioning and appetite were worse in the older group using either 65 or 70 years as the cutoff age. Age-related differences in the QLQ-C15-PAL scores varied as a function of age cutoff used and location of metastatic site irradiated. CONCLUSION: Based on the (EORTC) QLQ-C15-PAL, elderly advanced cancer patients have a different QOL profile. Similar observations have been reported with the (EORTC) QLQ-C30 questionnaire.

ABSTRACT

INTRODUCTION: Brain metastases occur in approximately 20-40% of cancer patients during the course of disease. As treatment for brain metastases is palliative over curative, quality of life (QoL) is emphasized over prolonged survival. The European Organization for Research and Treatment of Cancer (EORTC) QLQ-BN20 is a QoL assessment specific to brain neoplasms. We aim to provide a review of the current use of the EORTC QLQ-BN20 for patients with brain metastases. MATERIALS & METHODS: All studies utilizing the QLQ-BN20 for QoL assessment in patients receiving treatments related to brain metastases were included. Study information including treatment type, assessment periods, patient enrolment and all information pertaining to the QLQ-BN20 were extracted. RESULTS: A total of 13 studies were identified, five of which were randomized trials assessing prophylactic whole brain radiation for patients with small-cell lung cancer. The QLQ-BN20 was used in conjunction with the core QLQ-C30 questionnaire in all but one of the studies and together these comprised the entire QoL assessments for 11 of the 13 studies. Neurocognitive function assessments supplemented QoL in four studies and accompanying performance status indices used with the QLQ-BN20 varied. Compliance issues were commonly cited. QoL changes during study periods varied as improvements, deteriorations and stabilizations were all observed. CONCLUSION: QoL assessments should be conducted using disease-specific tools. Future studies should minimize patient burden in order to maximize data collection and accrual. A common set of QoL end points for patients with brain metastases should be created.
