A Qualitative Analysis of Medical Student Reflections Following Participation in a Canadian Radiation Oncology Studentship.

Exposure to radiation oncology in medical school curricula is limited; thus, mentorship and research opportunities like the Dr. Pamela Catton Summer Studentship Program attempt to bridge this gap and stimulate interest in the specialty. In 2021, the studentship was redesigned as virtual research, mentorship, and case-based discussions due to the COVID-19 pandemic. This study explores the impact of COVID-19 on the studentship, on students' perceptions of the program, and on medical training and career choice. Fifteen studentship completion essays during 2021-2022 were obtained and anonymized. Thematic analysis was performed to interpret the essays with NVivo. Two independent reviewers coded the essays. Themes were established by identifying connections between coded excerpts. Consensus was achieved through multiple rounds of discussion and iteratively reviewing each theme. Representative quotes were used to illustrate the themes. The themes confirmed the studentship was feasible during the pandemic. Perceived benefits of the program included mentorship and networking opportunities; gaining practical and fundamental knowledge in radiation oncology; developing clinical and research skills; and creating positive attitudes towards radiation oncology and the humanistic aspect of the field. The studentship supported medical specialty selection by helping define student values, shaping perceptions of the specialty, and promoting self-reflection upon students' personal needs. This study informs future iterations of the studentship to promote radiation oncology in Canadian medical school curricula. It serves as a model for studentships in other specialties that have limited exposure and similar challenges with medical student recruitment.

Mapping the Current State of Canadian Medical School Oncology Interest Groups.

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.

Feedback Delivery in an Academic Cancer Centre: Reflections From an R2C2-based Microlearning Course.

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.

Thymoma pathology and myasthenia gravis outcomes.

INTRODUCTION: There is limited evidence regarding the impact of World Health Organization (WHO) subtype of thymoma on post-thymectomy outcome of thymoma-associated myasthenia gravis (TAMG). The objective was to determine if the pathological subtypes of thymoma were associated with post-thymectomy outcomes of myasthenia gravis (MG), in patients with TAMG. METHODS: We performed a retrospective study of consecutive patients with TAMG who attended the neuromuscular clinic between January 2018 and December 2019 with a minimum follow-up of 1 y after thymectomy. Outcome measures were MG Impairment Index (MGII), single-simple question (SSQ), Myasthenia Gravis Foundation of America post-intervention status (MGFA PIS) and non-responder MG status at last assessment. RESULTS: Ninety-five patients were included; mean age at onset was 48.1 ± 12.1 y; 54(56.8%) were females. Thirteen patients developed MG post-thymectomy. The most common thymoma was WHO type B2 in 39 (41.1%). Most patients (40, 42.1%) had Masaoka stage II thymoma. There was no association of thymoma subtypes or Masaoka stage of disease with age, gender, MG phenotype, serology, post-thymectomy onset, interval from onset to thymectomy, MGII, SSQ, MGFA PIS, or non-responder status. Associations were found between positive serology and lower MGII (11.1 ± 14.2 vs 23 ± 12.9, P = .050), thymic follicular hyperplasia (TFH) and higher SSQ (89.3 ± 11.7 vs 80.1 ± 20.2, P-.043), and lack of recurrence and higher SSQ (84.1 ± 18 vs 72.5 ± 20, P = .037). DISCUSSION: The WHO pathological subtype of thymoma did not correlate with MG outcomes. However, positive acetylcholine antibody serology, presence of TFH, and non-recurrence of thymoma predict a favorable outcome.

A two-dimensional model of disrupted body integrity: initial evaluation in head and neck cancer.

PURPOSE: This cross-sectional study presents an initial psychometric evaluation of a two-dimensional (perceptual and evaluative) conceptualization and measure of disrupted body integrity (DBI)-illness-related disruption of the sense of the body as an integrated, smoothly functioning whole. METHODS: Male and female head and neck cancer (HNC) outpatients (N = 98) completed a questionnaire package prior to outpatient visits. MAIN OUTCOME MEASURES: The Disrupted Body Integrity Scale (DBIS) was developed to measure the perceptual and evaluative facets of DBI. Self-report measures of disfigurement, stigma, depressive symptoms, and negative affect were also completed. RESULTS: Almost all DBIS subscales demonstrated good internal consistency. Results largely supported the DBIS's construct validity. The majority of subscales correlated within the predicted range of r's = .40-.70. Almost all DBIS constructs were positively linked with either depressive symptoms or disfigurement. None correlated with positive affect, and only two subscales, abnormal sensations (perceptual) and physical vulnerability (evaluative), correlated with negative affect. DBIS constructs showed little relation with stigma, once disfigurement effects were controlled for. CONCLUSIONS: Findings offer preliminary evidence for the DBIS and the relevance of DBI in HNC. Further evaluation of DBI in disease adaptation and the DBIS's factor structure is warranted.

Concurrent once-daily versus twice-daily chemoradiotherapy in patients with limited-stage small-cell lung cancer (CONVERT): an open-label, phase 3, randomised, superiority trial.

BACKGROUND: Concurrent chemoradiotherapy is the standard of care in limited-stage small-cell lung cancer, but the optimal radiotherapy schedule and dose remains controversial. The aim of this study was to establish a standard chemoradiotherapy treatment regimen in limited-stage small-cell lung cancer. METHODS: The CONVERT trial was an open-label, phase 3, randomised superiority trial. We enrolled adult patients (aged ≥18 years) who had cytologically or histologically confirmed limited-stage small-cell lung cancer, Eastern Cooperative Oncology Group performance status of 0-2, and adequate pulmonary function. Patients were recruited from 73 centres in eight countries. Patients were randomly assigned to receive either 45 Gy radiotherapy in 30 twice-daily fractions of 1·5 Gy over 19 days, or 66 Gy in 33 once-daily fractions of 2 Gy over 45 days, starting on day 22 after commencing cisplatin-etoposide chemotherapy (given as four to six cycles every 3 weeks in both groups). The allocation method used was minimisation with a random element, stratified by institution, planned number of chemotherapy cycles, and performance status. Treatment group assignments were not masked. The primary endpoint was overall survival, defined as time from randomisation until death from any cause, analysed by modified intention-to-treat. A 12% higher overall survival at 2 years in the once-daily group versus the twice-daily group was considered to be clinically significant to show superiority of the once-daily regimen. The study is registered with ClinicalTrials.gov (NCT00433563) and is currently in follow-up. FINDINGS: Between April 7, 2008, and Nov 29, 2013, 547 patients were enrolled and randomly assigned to receive twice-daily concurrent chemoradiotherapy (274 patients) or once-daily concurrent chemoradiotherapy (273 patients). Four patients (one in the twice-daily group and three in the once-daily group) did not return their case report forms and were lost to follow-up; these patients were not included in our analyses. At a median follow-up of 45 months (IQR 35-58), median overall survival was 30 months (95% CI 24-34) in the twice-daily group versus 25 months (21-31) in the once-daily group (hazard ratio for death in the once daily group 1·18 [95% CI 0·95-1·45]; p=0·14). 2-year overall survival was 56% (95% CI 50-62) in the twice-daily group and 51% (45-57) in the once-daily group (absolute difference between the treatment groups 5·3% [95% CI -3·2% to 13·7%]). The most common grade 3-4 adverse event in patients evaluated for chemotherapy toxicity was neutropenia (197 [74%] of 266 patients in the twice-daily group vs 170 [65%] of 263 in the once-daily group). Most toxicities were similar between the groups, except there was significantly more grade 4 neutropenia with twice-daily radiotherapy (129 [49%] vs 101 [38%]; p=0·05). In patients assessed for radiotherapy toxicity, was no difference in grade 3-4 oesophagitis between the groups (47 [19%] of 254 patients in the twice-daily group vs 47 [19%] of 246 in the once-daily group; p=0·85) and grade 3-4 radiation pneumonitis (4 [3%] of 254 vs 4 [2%] of 246; p=0·70). 11 patients died from treatment-related causes (three in the twice-daily group and eight in the once-daily group). INTERPRETATION: Survival outcomes did not differ between twice-daily and once-daily concurrent chemoradiotherapy in patients with limited-stage small-cell lung cancer, and toxicity was similar and lower than expected with both regimens. Since the trial was designed to show superiority of once-daily radiotherapy and was not powered to show equivalence, the implication is that twice-daily radiotherapy should continue to be considered the standard of care in this setting.

Long-Term Outcomes After Concurrent Once- or Twice-Daily Chemoradiation in Limited-Stage Small Cell Lung Cancer: A Brief Report From the CONVERT Trial.

PURPOSE: CONVERT was a phase 3 international randomized clinical trial comparing once-daily (OD) and twice-daily (BD) radiation therapy (RT). This updated analysis describes the 6.5-year outcomes of these regimens delivered with conformal techniques. METHODS AND MATERIALS: CONVERT (NCT00433563) randomized patients 1:1 between OD RT (66 Gy/33 fractions/6.5 weeks) and BD RT (45 Gy/30 fractions/3 weeks), both delivered with concurrent cisplatin/etoposide. Three-dimensional conformal RT was mandatory, intensity-modulated RT was permitted, and elective nodal irradiation was not allowed. Prophylactic cranial irradiation was delivered at the discretion of treating clinicians. RT treatment planning was subject to central quality assurance. RESULTS: Five hundred forty-seven patients were recruited at 73 centers. The median follow-up for the surviving cohort (n = 164) was 81.2 months. The median survival for the OD and BD arms were 25.4 months (95% CI, 21.1-30.9) and 30.0 months (95% CI, 25.3-36.5; hazard ratio, 1.13; 95% CI, 0.92-1.38; P = .247). Performance status and tumor volume were associated with survival on multivariate analysis. No treatment-related deaths occurred subsequent to the initial analysis performed in 2017. Regarding late toxicity, 7 patients in the OD arm developed grade 3 esophagitis, 4 of which went on to develop stricture or fistulation, compared with no patients in the BD arm. Grade 3 pulmonary fibrosis occurred in 2 and 3 patients in the OD and BD arms, respectively. CONCLUSIONS: As the CONVERT trial did not demonstrate the superiority of OD RT and this regimen had a slightly worse toxicity profile after 80 months of follow-up, 45 Gy BD should remain the standard of care in limited stage small cell lung cancer.

Adapting an Adolescent and Young Adult Program Housed in a Quaternary Cancer Centre to a Regional Cancer Centre: Creating Equitable Access to Developmentally Tailored Support.

Adolescents and young adults (AYAs) with cancer, representing those between 15 and 39 years of age, face distinctive challenges balancing their life stage with the physical, emotional, and social impacts of a cancer diagnosis. These challenges include fertility concerns, disruptions to educational and occupational pursuits, issues related to body image and sexual health, and the need for age-appropriate psychosocial support within their communities. The Princess Margaret Cancer Centre (PM), a quaternary care center, established a specialized AYA program in 2014, offering holistic and developmentally tailored psychosocial support and currently, efforts are underway to expand this to other regions in the province to address the need for equitable access. The establishment process involves securing funding, conducting an environmental scan, identifying service gaps, developing clinical pathways, and implementing AYA supportive care. An accessible AYA program should also consider social determinants of health, social location, intersectionality, and an interdisciplinary health approach in understanding health inequities in AYA oncology care. This paper describes the processes implemented and challenges faced in creating a community-based AYA program beyond major resource-rich cities and efforts to address intersectionality.

Stereotactic Radiation Therapy in Early Non-Small Cell Lung Cancer and Interstitial Lung Disease: A Nonrandomized Clinical Trial.

Importance: Patients with interstitial lung disease (ILD) and early-stage non-small cell lung cancer (NSCLC) have been reported to be at high risk of toxic effects after stereotactic ablative radiotherapy (SABR), but for many patients, there are limited alternative treatment options. Objective: To prospectively assess the benefits and toxic effects of SABR in this patient population. Design, Setting, and Participants: This prospective cohort study was conducted at 6 academic radiation oncology institutions, 5 in Canada and 1 in Scotland, with accrual between March 7, 2019, and January 12, 2022. Patients aged 18 years or older with fibrotic ILD and a diagnosis of T1-2N0 NSCLC who were not candidates for surgical resection were enrolled. Intervention: Patients were treated with SABR to a dose of 50 Gy in 5 fractions every other day. Main Outcomes and Measures: The study prespecified that SABR would be considered worthwhile if median overall survival-the primary end point-was longer than 1 year, with a grade 3 to 4 risk of toxic effects less than 35% and a grade 5 risk of toxic effects less than 15%. Secondary end points included toxic effects, progression-free survival (PFS), local control (LC), quality-of-life outcomes, and changes in pulmonary function. Intention-to-treat analysis was conducted. Results: Thirty-nine patients enrolled and received SABR. Median age was 78 (IQR, 67-83) years and 59% (n = 23) were male. At baseline, 70% (26 of 37) of patients reported dyspnea, median forced expiratory volume in first second of expiration was 80% (IQR, 66%-90%) predicted, median forced vital capacity was 84% (IQR, 69%-94%) predicted, and median diffusion capacity of the lung for carbon monoxide was 49% (IQR, 38%-61%) predicted. Median follow-up was 19 (IQR, 14-25) months. Overall survival at 1 year was 79% (95%, CI 62%-89%; P < .001 vs the unacceptable rate), and median overall survival was 25 months (95% CI, 14 months to not reached). Median PFS was 19 months (95% CI, 13-28 months), and 2-year LC was 92% (95% CI, 69%-98%). Adverse event rates (highest grade per patient) were grade 1 to 2: n = 12 (31%), grade 3: n = 4 (10%), grade 4: n = 0, and grade 5: n = 3 (7.7%, all due to respiratory deterioration). Conclusions and Relevance: In this trial, use of SABR in patients with fibrotic ILD met the prespecified acceptability thresholds for both toxicity and efficacy, supporting the use of SABR for curative-intent treatment after a careful discussion of risks and benefits. Trial Registration: ClinicalTrials.gov Identifier: NCT03485378.

Stereotactic Radiation for Ultra-Central Non-Small Cell Lung Cancer: A Safety and Efficacy Trial (SUNSET).

PURPOSE: The use of stereotactic body radiation therapy for tumors in close proximity to the central mediastinal structures has been associated with a high risk of toxicity. This study (NCT03306680) aimed to determine the maximally tolerated dose of stereotactic body radiation therapy for ultracentral non-small cell lung carcinoma, using a time-to-event continual reassessment methodology. METHODS AND MATERIALS: Patients with T1-3N0M0 (≤6 cm) non-small cell lung carcinoma were eligible. The maximally tolerated dose was defined as the dose of radiation therapy associated with a ≤30% rate of grade (G) 3 to 5 prespecified treatment-related toxicity occurring within 2 years of treatment. The starting dose level was 60 Gy in 8 daily fractions. The dose-maximum hotspot was limited to 120% and within the planning tumor volume; tumors with endobronchial invasion were excluded. This primary analysis occurred 2 years after completion of accrual. RESULTS: Between March 2018 and April 2021, 30 patients were enrolled at 5 institutions. The median age was 73 years (range, 65-87) and 17 (57%) were female. Planning tumor volume was abutting proximal bronchial tree in 19 (63%), esophagus 5 (17%), pulmonary vein 1 (3.3%), and pulmonary artery 14 (47%). All patients received 60 Gy in 8 fractions. The median follow-up was 37 months (range, 8.9-51). Two patients (6.7%) experienced G3-5 adverse events related to treatment: 1 patient with G3 dyspnea and 1 G5 pneumonia. The latter had computed tomography findings consistent with a background of interstitial lung disease. Three-year overall survival was 72.5% (95% CI, 52.3%-85.3%), progression-free survival 66.1% (95% CI, 46.1%-80.2%), local control 89.6% (95% CI, 71.2%-96.5%), regional control 96.4% (95% CI, 77.2%-99.5%), and distant control 85.9% (95% CI, 66.7%-94.5%). Quality-of-life scores declined numerically over time, but the decreases were not clinically or statistically significant. CONCLUSIONS: Sixty Gy in 8 fractions, planned and delivered with only a moderate hotspot, has a favorable adverse event rate within the prespecified acceptability criteria and results in excellent control for ultracentral tumors.

The psychosocial impact of stigma in people with head and neck or lung cancer.

BACKGROUND: Lung and head and neck cancers are widely believed to produce psychologically destructive stigma because they are linked to avoidable risk-producing behaviors and are highly visible, but little research has tested these ideas. We examined cancer-related stigma, its determinants, and its psychosocial impact in lung (n = 107) and head and neck cancer survivors (n = 99) ≤ 3 years post-diagnosis. We investigated cancer site, self-blame, disfigurement, and sex as determinants, benefit finding as a moderator, and illness intrusiveness as a mediator of the relation between stigma and its psychosocial impact. METHODS: Prospective participants received questionnaire packages 2 weeks before scheduled follow-up appointments. They self-administered widely used measures of subjective well-being, distress, stigma, self-blame, disfigurement, illness intrusiveness, and post-traumatic growth. RESULTS: As hypothesized, stigma correlated significantly and uniquely with negative psychosocial impact, but contrary to common beliefs, reported stigma was comparatively low. Reported stigma was higher in (i) men than women, (ii) lung as compared with head and neck cancer, and (iii) people who were highly disfigured by cancer and/or its treatment. Benefit finding buffered stigma's deleterious effects, and illness intrusiveness was a partial mediator of its psychosocial impact. CONCLUSIONS: Stigma exerts a powerful, deleterious psychosocial impact in lung and head and neck cancers, but is less common than believed. Patients should be encouraged to remain involved in valued activities and roles and to use benefit finding to limit its negative effects.

Advanced lung cancer patients' experience with continuity of care and supportive care needs.

As cancer care becomes increasingly complex, the ability to coordinate this care is more difficult for health care providers, patients and their caregivers alike. Despite the widely recognized need for improving continuity and coordination of care, the relationship of continuity of care with patient outcomes has yet to be elucidated. Our study's main finding is that the Continuity and Coordination subscale of the widely used Picker System of Ambulatory Cancer Care Survey is able to distinguish between lung cancer patients with unmet supportive care needs and those without. Specifically, this study shows a new association between this widely implemented continuity and coordination survey and the 'psychological needs' domain, as well as the 'health system and information' domains of supportive care needs. The finding provides support for the idea that interventions to improve continuity may impact tangible indicators of patient care such as supportive care needs being met. The study focuses attention on continuity of care as an important aspect of optimizing outcomes in cancer care.

Dosimetric and clinical impact of 3D vs. 2D planning in palliative radiotherapy for bone metastases.

PURPOSE: The incorporation of three-dimensional (3D) planning for the treatment of bone metastases has been embraced in many North American practices with assumed superior tumor targeting, sparing of normal structures, and improvement in patient outcomes. The goal of our project was to evaluate the dosimetric and clinical impact of 3D vs. two-dimensional (2D) planning for patients who require simple palliative radiotherapy techniques (≤ 2 beams) for bone metastases. METHODS: Patients undergoing palliative radiation therapy for bone metastases were eligible. The study oncologists first documented the intended treatment target, defined the treatment target/field using digital radiographs (2D), followed by using full 3D planning computerized tomography volumetric datasets. Treatment plans were compared dosimetrically, and patient-reported outcomes (pain, fatigue, anorexia, and nausea) were compared against a historical cohort treated with 2D plans. RESULTS: Eighty-five patients were enrolled in the study group. Review of the 3D datasets led to changes in the target area of interest in 44/85 (52 %) of cases, of which 21/85 (25 %) were clinically significant. 3D plans resulted in superior target coverage and normal tissue sparing. There was no significant difference in patient-reported outcomes however. CONCLUSION: 3D radiotherapy planning resulted in superior treatment plans but we were unable to demonstrate a significant benefit in clinical outcomes. Prospective study designs are needed to describe the contemporary expectation of palliative radiotherapy for bone metastases in the modern era of 3D planning.

Radiotherapy for Lung Metastases: Conventional to Stereotactic Body Radiation Therapy.

The lung parenchyma and adjacent tissues are one of the most common sites of metastatic disease. Traditionally, the approach to treatment of a patient with lung metastases has been with systemic therapy, with radiotherapy being reserved for palliative management of symptomatic disease. The concept of oligo metastatic disease has paved the way for more radical treatment options, administered either alone or as local consolidative therapy in addition to systemic treatment. The modern-day management of lung metastases is guided by a number of factors, including the number of lung metastases, extra-thoracic disease status, overall performance status, and life expectancy, which all help determine the goals of care. Stereotactic body radiotherapy (SBRT) has emerged as a safe and effective method in locally controlling lung metastases, in the oligo metastatic or oligo-recurrent setting. This article outlines the role of radiotherapy in multimodality management of lung metastases.

BRACHY: A Randomized Trial to Evaluate Symptom Improvement in Advanced Non-Small Cell Lung Cancer Treated With External Beam Radiation With or Without High-Dose-Rate Intraluminal Brachytherapy.

PURPOSE: Uncontrolled studies suggest that the addition of high-dose-rate intraluminal brachytherapy (HDRIB) to external beam radiation therapy (EBRT) may improve palliation for patients with advanced non-small cell lung cancer (NSCLC). The purpose of this study was to evaluate the potential clinical benefit of adding HDRIB to EBRT in a multicenter randomized trial. METHODS AND MATERIALS: Patients with symptomatic stage III or IV NSCLC with endobronchial disease were randomized to EBRT (20 Gy in 5 daily fractions over 1 week or 30 Gy in 10 daily fractions over 2 weeks) or the same EBRT plus HDRIB (14 Gy in 2 fractions separated by 1 week). The primary outcome was the proportion of patients who achieved symptomatic improvement in patient-reported overall lung cancer symptoms on the Lung Cancer Symptom Scale (LCSS) at 6 weeks after randomization. Secondary outcomes included improvement in individual symptoms, symptom-progression-free survival, overall survival, and toxicity. The planned sample size was 250 patients based on detection of symptomatic improvement from 40% to 60% with a 2-sided α of .05 and 80% power. RESULTS: A total of 134 patients were randomized over 4.5 years: 67 to each arm. The study closed early owing to slow accrual. The mean age was 69.8 years, and 67% of patients had metastatic disease. At 6 weeks, 19 patients (28.4%) in the EBRT arm and 20 patients (29.9%) in the EBRT plus HDRIB arm experienced an improvement in lung cancer symptoms (P = .84). When limited to patients who completed the LCSS, percentages were 40.4% versus 47.6%, respectively (P = .49). Between group differences in mean change scores (0.3-0.5 standard deviations) in favor of EBRT plus HDRIB were observed for overall symptoms, but only hemoptysis was significantly improved (P = .03). No significant differences were observed in progression-free or overall survival. Grade 3/4 toxicities were similar between groups. CONCLUSIONS: Small to moderate improvements were seen in symptom relief with the combined therapy, but they did not reach statistical significance. Further research is necessary before recommending HDRIB in addition to EBRT for palliation of lung cancer symptoms.

Alleviating emotional exhaustion in oncology nurses: an evaluation of Wellspring's "Care for the Professional Caregiver Program".

A high level of burnout has been demonstrated in oncologists, nurses, and other health professionals. Interventions developed in response demonstrate mixed results. Wellspring, a community cancer support organization, has developed a 1-day session called Care for the Professional Caregiver Program (CPCP) and has delivered it to over 700 healthcare workers. The present study assessed the effects of the CPCP on three groups of oncology nurses (pediatric, surgical, and general oncology staff) and one group of nurse managers. Subjects completed the Maslach burnout inventory (MBI), the General health questionnaire (GHQ) and the short form of the Marlowe-Crowne social desirability scale (M-C) prior to receiving the intervention. They then completed the MBI and GHQ at 1-month and 7-month follow-ups. Six months after the original session, a small subset of subjects was randomly selected to participate in a 1-day CPCP booster session. At baseline, one third of the nurses showed high burnout on the MBI. The nurses demonstrated a significant decrease in emotional exhaustion and an improvement on the GHQ, at the 1-month follow-up testing (p = 0.003 and 0.001, respectively) and 7-month follow-up testing (p = 0.002 and 0.001). The booster session proved difficult to deliver because of institutional scheduling problems due to nurse shortages, so only a small percentage (22%) of the sample participated; however, it was well received. Thus, the CPCP is effective in ameliorating emotional exhaustion, an intrinsic aspect of burnout.

Understanding the needs of lung cancer patients during the pre-diagnosis phase.

Patients with lung cancer have numerous and varying needs spanning across the cancer trajectory; however, only limited research has focused specifically on the pre-diagnosis phase. A multicentre cross-sectional survey was conducted to explore the experience of lung cancer patients during the pre-diagnosis phase. High levels of anxiety were reported by many participants (45.6 %). Informational (32.1 %), and emotional (24.1 %) needs were reported as most important; the majority (89.0 %) reported these needs were met. Most participants sought information throughout, with many (38.6 %) rating their oncology health care providers to be the best source of information. The majority (70.0 %) reported that they were not directed to any resources to help address their anxiety. During pre-diagnosis, informational and emotional needs appear most important, and for the majority, these were reportedly met. Although many experienced high levels of anxiety, few were directed to resources to address it.

A comparative study of patient-reported outcomes after contemporary radiation techniques for prostate cancer.

PURPOSE: We aim to compare health-related quality of life (HRQoL) deterioration at 12 months in low-and intermediate-risk prostate cancer (PCa) patients treated with stereotactic ablative radiotherapy (SABR), high dose-rate brachytherapy (HDR) monotherapy and HDR boost. MATERIAL AND METHODS: Patients treated as part of 7 prospective clinical trials were included. All patients had low-or intermediate-risk PCa. Three strategies were considered: SABR, HDR monotherapy and HDR boost. HRQoL was prospectively measured at baseline and 12 months in all trials, using the Expanded Prostate Index Composite (EPIC). A minimally important difference (MID) was defined as a deterioration of HRQoL scores at 12 months compared to baseline ≥0.5 standard deviation of baseline score. Univariate and multivariable logistic regression using generalized estimating equations were used to compare the proportion of patients having MID between groups. A set of sensitivity analyses was conducted. RESULTS: 648 patients were included: 288, 173 and 187 respectively in the SABR, HDR monotherapy and HDR boost group. On univariate and multivariable analyses, SABR and HDR monotherapy compared to HDR boost, were associated with less deterioration in the urinary (38%, 40% vs. 55%; OR:0.543, 95%CI:0.320-0.922, p = 0.024; OR:0.468, 95%CI:0.432-0.507, p < 0.001) and sexual domains (38%, 42% vs. 47%; OR:0.762, 95%CI:0.645-0.900, p = 0.001; OR: 0.786, 95%CI:0.650-0.949, p = 0.012). These findings wererobust to a variety ofsensitivity analyses. CONCLUSION: Recent monotherapeutic approaches for low- and intermediate-risk PCa are associated with the preservation of patients HRQoL. Ultimately, the questions of efficacy, toxicity, and HRQoL will be best answered by a randomized clinical trial.

Health related quality of life outcomes following stereotactic body radiotherapy in patients with oligo-metastatic disease: A systematic review and individual patient data meta-analysis.

INTRODUCTION: Published health-related quality of life (HRQOL) outcomes are lacking in patients treated for oligo-metastatic disease (OMD). The aim of this systematic review and individual patient data meta-analysis is to determine the effect of stereotactic body radiotherapy (SBRT) on HRQOL outcomes of patients with OMD. METHODS: Studies screened included adults with extra-cranial OMD, defined as ≤ 5 metastases, SBRT intended as definitive treatment, and HRQOL as primary or secondary outcome. Primary outcome was change in HRQOL at 12-months from baseline in patients with OMD who received SBRT (versus not), reported as standardized mean difference (SMD). RESULTS: A total of 7556 publications were identified, four studies met inclusion criteria (2 single arm interventional studies and 2 randomised controlled trials [RCTs]), and individual patient data was available from 3 studies (175 patients). In the two RCTs, there was no SS difference in the SMD between patients who received SBRT and those that did not (0.09 [95 % CI -0.32, 0.5], P = 0.66). On meta-analysis of patients (N = 107) who received SBRT the SMDwas -0.23 (95 % CI [-0.42, -0.04], versus -0.25 (95 % CI [-0.57, 0.07]) in those who did not (N = 37) receive SBRT, demonstrating a small deterioration from baseline. CONCLUSION: In patients with OMD, there is no difference in HRQOL at 12-months from baseline between patients who received SBRT and those that did not. However, a small HRQOL deterioration was found in both groups of patients. More in-depth analysis of relevant HRQOL domains, in the setting of OMD, is required to better understand the potential impact of SBRT.

Palliative Radiation for Advanced Central Lung Tumors With Intentional Avoidance of the Esophagus (PROACTIVE): A Phase 3 Randomized Clinical Trial.

IMPORTANCE: Palliative thoracic radiotherapy (RT) can alleviate local symptoms associated with advanced non-small cell lung cancer (NSCLC), but esophagitis is a common treatment-related adverse event. Whether esophageal-sparing intensity-modulated RT (ES-IMRT) achieves a clinically relevant reduction in esophageal symptoms remains unclear. OBJECTIVE: To examine whether ES-IMRT achieves a clinically relevant reduction in esophageal symptoms compared with standard RT. DESIGN, SETTING, AND PARTICIPANTS: Palliative Radiation for Advanced Central Lung Tumors With Intentional Avoidance of the Esophagus (PROACTIVE) is a multicenter phase 3 randomized clinical trial that enrolled patients between June 24, 2016, and March 6, 2019. Data analysis was conducted from January 23, 2020, to October 22, 2021. Patients had up to 1 year of follow-up. Ninety patients at 6 tertiary academic cancer centers who had stage III/IV NSCLC and were eligible for palliative thoracic RT (20 Gy in 5 fractions or 30 Gy in 10 fractions) were included. INTERVENTIONS: Patients were randomized (1:1) to standard RT (control arm) or ES-IMRT. Target coverage was compromised to ensure the maximum esophagus dose was no more than 80% of the RT prescription dose. MAIN OUTCOMES AND MEASURES: The primary outcome was esophageal quality of life (QOL) 2 weeks post-RT, measured by the esophageal cancer subscale (ECS) of the Functional Assessment of Cancer Therapy: Esophagus questionnaire. Higher esophageal cancer subscale scores correspond with improved QOL, with a 2- to 3-point change considered clinically meaningful. Secondary outcomes included overall survival, toxic events, and other QOL metrics. Intention-to-treat analysis was used. RESULTS: Between June 24, 2016, and March 6, 2019, 90 patients were randomized to standard RT or ES-IMRT (median age at randomization, 72.0 years [IQR, 65.6-80.3]; 50 [56%] were female). Thirty-six patients (40%) received 20 Gy and 54 (60%) received 30 Gy. For the primary end point, the mean (SD) 2-week ECS score was 50.5 (10.2) in the control arm (95% CI, 47.2-53.8) and 54.3 (7.6) in the ES-IMRT arm (95% CI, 51.9-56.7) (P = .06). Symptomatic RT-associated esophagitis occurred in 24% (n = 11) of patients in the control arm vs 2% (n = 1) in the ES-IMRT arm (P = .002). In a post hoc subgroup analysis based on the stratification factor, reduction in esophagitis was most evident in patients receiving 30 Gy (30% [n = 8] vs 0%; P = .004). Overall survival was similar with standard RT (median, 8.6; 95% CI, 5.7-15.6 months) and ES-IMRT (median, 8.7; 95% CI, 5.1-10.2 months) (P = .62). CONCLUSIONS AND RELEVANCE: In this phase 3 randomized clinical trial, ES-IMRT did not significantly improve esophageal QOL but significantly reduced the incidence of symptomatic esophagitis. Because post hoc analysis found that reduced esophagitis was most evident in patients receiving 30 Gy of RT, these findings suggest that ES-IMRT may be most beneficial when the prescription dose is higher (30 Gy).
