RESUMO

AIMS: Clinical practice guidelines recommend palliative chemotherapy for most patients with metastatic colorectal cancer. However, outcomes observed in the real world compared with patients enrolled in clinical trials have not been sufficiently described. The objective of this study was to evaluate the delivery and outcomes of first-line palliative chemotherapy administered to patients with colorectal cancer in routine clinical practice compared with clinical trials. MATERIALS AND METHODS: Using linked health administrative data, we carried out a retrospective population-level cohort study on patients diagnosed with colorectal cancer in Ontario, Canada from 2010 to 2019. Patient, disease and treatment characteristics were summarised. The primary outcome was median overall survival, stratified by treatment prescribed and age. Demographics and outcomes in this real-world population were compared with those from pivotal clinical trials. A multivariable Cox regression model reporting hazard ratios and 95% confidence intervals was used to determine factors associated with survival in patients receiving systemic treatment. RESULTS: We identified 70 987 patients with a new diagnosis of colorectal cancer, of which 4613 received first-line chemotherapy for unresectable locally advanced or metastatic disease and formed the study cohort. Fifty-eight per cent were male and the mean age was 63 years. Most had colon cancer (69%), at least one comorbidity (73%) and lived in an urban location (79%). Less than half (47%) had surgery after diagnosis. The most common regimen prescribed was folinic acid, 5-fluorouracil and irinotecan (FOLFIRI) with bevacizumab or epidermal growth factor receptor inhibitors (EGFRi; n = 2784, 60%). Among all treated patients, the median overall survival was 17.1 months, with survival difference by regimen [median overall survival 18.3 for FOLFIRI with bevacizumab or EGFRi, 19.6 for folinic acid, 5-fluorouracil and oxaliplatin (FOLFOX)/capecitabine, oxaliplatin (XELOX) with bevacizumab or EGFRi, 13.6 for FOLFIRI alone and 7.8 for 5-fluorouracil or capecitabine]. Patients aged >80 years were most likely to have received single-agent 5-fluorouracil or capecitabine, and had inferior overall survival compared with their younger counterparts. Compared with pivotal clinical trials, patients in the real world had inferior overall survival outcomes despite similar demographic characteristics (including age and sex). CONCLUSIONS: In this real-world population-based analysis of patients receiving first-line chemotherapy for unresectable locally advanced or metastatic colorectal cancer, survival outcomes were inferior to those reported in randomised trials despite similarities in age and sex. This information can be used when counselling patients in routine practice about expected outcomes.

RESUMO

BACKGROUND: Cancer incidence and mortality are rapidly rising in Africa. National Cancer Control Plans (NCCPs have contributed to a reduction in the burden of some preventable cancers, availing early diagnosis and adequate treatment modalities and palliative care, while sustaining them with sufficient monitoring systems. knowledge we undertook a cross-sectional survey across continental Africa to understand the presence of NCCPs, availability of early detection and screening policies and the status of health financing pertaining to cancer. METHODS: Through an online survey, we approached key cancer care staff in 54 countries. Questions were themed in 3 main areas - Cancer registries and national cancer control plans (NCCPs) availability in countries, Cancer screening, diagnosis and management capacity, Financing in cancer care. RESULTS: On 54 approached respondents, we received 32 responses. 88 % of responding countries have active national cancer registries, 75 % with NCCPs and 47 % with cancer screening policies and practices. Universal Health Coverage is available in 40 % of countries. CONCLUSION: Our study shows that there is a scarcity of NCCPs in Africa. Deliberate investment in cancer registry and clinical services is key to improving access to care and ultimately reduce cancer mortality in Africa.

RESUMO

AIMS: Most randomised controlled trials (RCTs) in oncology are now funded by the pharmaceutical industry. We explore the extent to which RCT design, results and interpretation differ between industry-funded and non-industry-funded RCTs. MATERIALS AND METHODS: In this cross-sectional analysis, a structured literature search was used to identify all oncology RCTs published globally during 2014-2017. Industry funding was identified based on explicit statements in the publication. Descriptive statistics were used to compare elements of trial methodology and output between industry- and non-industry-funded RCTs. RESULTS: The study sample included 694 RCTs; 71% were funded by industry. Industry-funded trials were more likely to test systemic therapy (97% versus 62%; P < 0.001), palliative-intent therapy (71% versus 41%; P < 0.001) and study breast cancer (20% versus 12%; P < 0.001). Industry-funded trials were larger (median sample size 474 versus 375; P < 0.001) and more likely to meet their primary end point (49% versus 41%; P < 0.001). Among positive trials, there were no differences in the magnitude of benefit between industry- and non-industry-funded RCTs. Trials funded by industry were published in journals that had a significantly higher median impact factor (21, interquartile range 7, 28) than non-industry-funded trials (impact factor 12, interquartile range 5, 24; P = 0.005); this persisted when adjusted for whether a trial was positive or negative. CONCLUSIONS: The vast majority of oncology RCTs are now funded by industry. Industry-funded trials are larger, more likely to be positive, predominantly test systemic therapies in the palliative setting and are published in higher impact journals than trials without industry support.

RESUMO

AIMS: In the pivotal Trastuzumab for Gastric Cancer (ToGA) trial, trastuzumab improved median survival in patients with advanced HER-2-positive gastric and gastroesophageal cancer from 11.1 to 13.8 months; however, its effectiveness in routine clinical practice has not been evaluated. Our objective was to evaluate the uptake and outcomes of trastuzumab in a population-based cohort of patients with oesophageal, gastroesophageal and gastric cancer in Ontario, Canada. MATERIALS AND METHODS: The Ontario Cancer Registry and linked treatment records were used to identify all patients with oesophageal, gastroesophageal and gastric cancer treated with trastuzumab during 2012-2017. Outcomes were analysed from the time of first trastuzumab cycle and included a primary outcome (survival) and secondary outcomes (uptake, delivery, 30-day hospital admission and 30-day mortality). Trends over the study period and survival were evaluated. RESULTS: In total, 476 patients with oesophageal, gastroesophageal and gastric cancer received trastuzumab during the study period. The mean age was 62 years, 78% (370/476) were male, and 65% (312/476) had gastric cancer. The annual number of patients receiving trastuzumab increased over the study period (53 in 2012 and 101 in 2017). The median number of cycles of trastuzumab delivered was six. Thirty-day hospital admission and mortality rates were 17% and 4%, respectively. The median overall survival was 282 days (9.3 months). CONCLUSIONS: The median survival of patients treated with trastuzumab for advanced oesophageal, gastroesophageal and gastric cancer in routine practice is substantially less than that observed in the pivotal clinical trial. Studies of comparative effectiveness using real-world data offer insight into outcomes achieved in routine practice.

RESUMO

Background: Bleomycin is commonly used to treat advanced testicular cancer and can be associated with severe pulmonary toxicity. The primary objective of the present study was to describe the use of pulmonary function tests (pfts) and chest imaging before, during, and after treatment with bleomycin. Methods: To identify all incident cases of testicular cancer treated with bleomycin-based chemotherapy in the Canadian province of Ontario during 2005-2010, the Ontario Cancer Registry was linked with chemotherapy treatment records. Health administrative databases were used to describe use of pfts, chest imaging, and physician visits for respiratory complaints. Results: Of 394 patients treated with orchiectomy and chemotherapy who received at least 1 dose of bleomycin, 93% had complete chemotherapy records available. In the 4 weeks before, during, and within 2 years after finishing bleomycin-based chemotherapy, pfts were performed in 17%, 17%, and 29% of patients respectively. Chest imaging was performed in 68%, 62%, and 98% of patients in the same time periods. In the 2 years after bleomycin-based chemotherapy, 23% of treated patients had a physician visit for respiratory symptoms. That rate was substantially higher for men with greater exposure to bleomycin: 40% (24 of 60) for 10-12 doses bleomycin compared with 21% (53 of 250) for 7-9 doses and with 14% (8 of 58) for 1-6 doses (p = 0.002). Conclusions: Quality improvement initiatives are needed to increase baseline rates of chest imaging within 4 weeks of starting chemotherapy for testicular cancer; to understand why such a high proportion of men have chest imaging during bleomycin-based chemotherapy; and to mitigate the excess pulmonary toxicity seen with increasing exposure to bleomycin.

RESUMO

AIMS: Venous thromboembolism (VTE) is a potential complication among germ cell tumour patients. We evaluated the incidence rate, timing and factors associated with VTE among patients with germ cell cancer in routine practice. MATERIALS AND METHODS: The Ontario Cancer Registry was linked to electronic records of treatment to identify all cases of testicular cancer treated in Ontario during 2000-2010. Administrative databases were used to identify VTE in the 3 months before and 5 years after orchiectomy. We explored patient-, disease- and treatment-related factors associated with VTE among all patients as well as those with detailed chemotherapy records available. RESULTS: During 2000-2010, 2650 patients underwent orchiectomy for testicular cancer; among this cohort, 920 (33%) received chemotherapy. The VTE rate was 8% (69/920) among patients treated with chemotherapy and 0.6% (11/1730) among those without chemotherapy. Among the patients treated with chemotherapy who had VTE, 13% (9/69) occurred in the month before starting chemotherapy, 62% (42/69) in the first 3 months after starting and 25% thereafter. For patients who received three and four cycles, VTE rates were 8% (21/258) and 16% (19/121), respectively. In adjusted analyses, the only factor independently associated with VTE was increasing number of cycles (odds ratio 3.91 for four cycles, odds ratio 1.63 for three cycles (P = 0.022) compared with one to two cycles). CONCLUSION: This population-based study confirms findings from institutional case series regarding the high rate of VTE among patients with germ cell tumours treated with chemotherapy. Future studies should evaluate the extent to which VTE prophylactic strategies might mitigate this risk.

RESUMO

AIMS: The workload pressure on medical oncologists will increase in the near future. There are no comprehensive data available about the current workload of medical oncologists in Europe. Here we report the European results of a global survey of the workload of medical oncologists. MATERIALS AND METHODS: An online survey was distributed through a snowball method via national oncology societies to chemotherapy-prescribing physicians in 21 European countries. We compared the workload of medical oncologists in Eastern European countries (EECs) and Western European countries (WECs). The primary measure of workload was the annual number of new cancer patient consults seen per oncologist. RESULTS: In total, 495 oncologists from 16 European countries completed our survey: 100 from seven EECs and 395 from nine WECs. The median number of annual consults per medical oncologist was 225 in EECs compared with 175 in WECs (P < 0.001). The proportion of medical oncologists seeing more than 300 consults/year was 35% (35/100) in EECs compared with 18% (68/395) in WECs. The median number of patients seen in a full day clinic was 25 in EECs and 15 in WECs (P < 0.001). Eastern European medical oncologists reported spending a median of 25 min per new consultation compared with 45 min in WECs (P < 0.001). The top two reported barriers in both EECs and WECs to patient care were high clinical volumes and insufficient time for reading. CONCLUSION: The clinical workload of medical oncologists in EECs was substantially higher than in WECs. European health policymakers and educators need to address existing disparities in the workload of medical oncologist, undertake plans for future workforce supply and consider alternative models of care.

RESUMO

AIMS: Neurotoxicity may affect the quality of life of survivors of testicular cancer. Understanding the burden of neurotoxicity is important to guide survivorship care. A population-based study was undertaken to describe the proportion of patients in the 'real world' with neurotoxicity. MATERIALS AND METHODS: A population-based, retrospective, cohort study of patients with advanced testicular cancer treated in the province of Ontario. The Ontario Cancer Registry was linked to electronic treatment records to identify all incident cases of testicular cancer during 2000-2010. Administrative databases were used to describe health system visits for symptoms potentially related to neurotoxicity. Health system visit rates were explored by number of chemotherapy cycles among patients treated during 2005-2010 for whom complete chemotherapy details were available. RESULTS: During 2000-2010, 2650 patients underwent an orchiectomy for testicular cancer; 920 (33%) also received chemotherapy. The proportion of patients with health system visits for neurotoxicity in the 2 years before surgery compared with the 2 years after surgery remained stable among patients treated with orchiectomy alone (18% [303/1730] versus 18% [316/1730], P = 0.523); however, there was a substantial increase among patients treated with chemotherapy (16% [151/920] versus 25% [231/920], P < 0.001). Among patients treated with chemotherapy in 2005-2010 for whom complete details were available regarding number of treatment cycles there was a dose-response effect. The increase in health system visits for neurotoxicity from 2 years before compared with 2 years after orchiectomy was greater among patients treated with four cycles of chemotherapy (17% [21/121] versus 37% [45/121]) and three cycles of chemotherapy (17% [45/258] versus 28% [72/258]) compared with those treated with one to two cycles of chemotherapy (<13% [<6/45] versus 20% [9/45], P = 0.013). CONCLUSIONS: This population-based study suggests that symptoms of neurotoxicity are common among survivors of testicular cancer and that this seems to be driven by increasing exposure to chemotherapy. Clinicians should carefully evaluate patients for neurotoxicity during the survivorship phase of treatment.

RESUMO

AIM: Up to 30% of patients with squamous cell cancer of the anus (SCCA) will require a salvage abdominoperineal resection (APR) for either persistent or recurrent disease. The objective of this study was to assess cancer-related outcomes in patients with (i) persistent or (ii) recurrent SCCA. METHOD: Embase and MEDLINE were searched. Publications were included if they assessed overall survival (OS), disease-free survival (DFS) and locoregional recurrence or metastatic disease after salvage APR for persistent or recurrent SCCA. RESULTS: A total of 28 retrospective case series (study size ranged from nine to 111) met our inclusion criteria. The median time to salvage APR was 2.6 months [interquartile range (IQR) 2.6-5.0 months, six studies] for persistent disease and 27.6 months (IQR 15.0-32.7 months, five studies) for recurrent disease. The median 5-year OS from the time of salvage APR was 45.0% (IQR 32.0%-52.3%, 10 studies) for persistent disease and 51.0% (IQR 36.0%-60.9%, 11 studies) for recurrent disease. The median 5-year DFS following salvage APR was 44.0% (IQR 29.5%-53.0%, 10 studies) for all patients. Following salvage APR, the median locoregional recurrence rate was 23.5% (IQR 15.8%- 46.9%, 19 studies) and 9.0% (IQR 6.4%-13.3%, 16 studies) of patients developed metastatic disease after salvage APR. CONCLUSION: Our review characterizes the best evidence for outcomes following salvage APR for patients with persistent or recurrent SCCA. The evidence is limited by the quality of included studies, as many were single centre case series.

RESUMO

AIMS: New targeted drugs and immune therapies reported since 2010 for metastatic or unresectable melanoma (MM) have shown improved survival in randomised trials. We studied the uptake of these new drugs and their impact on population-based survival. MATERIALS AND METHODS: This was a retrospective, population-based cohort study of all patients treated for MM in Ontario 2007-2015. Provincial administrative sources covering the whole population identified palliative systemic therapy, radiotherapy and metastasis surgery. Temporal trends in utilisation and survival were investigated, as was survival of treatments predefined as 'new drugs' (BRAF or MEK inhibitors, anti-CTLA4 and anti-PD-1 antibodies). RESULTS: We identified 2793 treated MM patients. First treatment was systemic therapy (46%), radiotherapy (41%) and metastasis surgery (14%). Systemic treatment increased from 53% of patients (2007) to 75% (2015). New drug treatments increased from <6% of known first-line regimens in 2007 to 82% in 2015. One and 2 year overall survival was 28% and 15%, respectively, for all MM 2007-2009, rising to 46% and 35% for 2014-2015 (adjusted hazard ratio 0.56, 95% confidence interval 0.49-0.63, P < 0.0001). Survival gains were observed primarily among those cases initially treated with systemic therapy, which became dominated by the use of new drugs over the study period (2 year overall survival 16% 2007-2009 versus 44% 2014-2015; adjusted hazard ratio 0.46, 95% confidence interval 0.38-0.56, P < 0.0001). CONCLUSIONS: Utilisation of new targeted drugs and immune therapies for MM has increased considerably in routine practice 2007-2015. Consistent with the results of clinical trials, adoption was associated with substantial increases in survival of patients in the general population.

RESUMO

Background: In 2000, a Canadian task force recommended that medical oncologists (mos) meet a target of 160-175 new patient consultations per year. Here, we report the Canadian results of a global survey of mo workload compared with mo workload in other high-income countries (hics). Methods: Using a snowball method, an online survey was distributed by national oncology societies to chemotherapy-prescribing physicians in 22 hics (World Bank criteria). The survey was distributed within Canada to all members of the Canadian Association of Medical Oncologists. Workload was measured as the annual number of new cancer patient consults per oncologist. Results: The survey was completed by 782 oncologists from hics, including 58 from Canada. Median annual consults per mo were 175 in Canada compared with 125 in other hics. The proportions of mos having 100 or fewer consults or more than 300 consults per year were 3% (2/58) and 5% (3/58) in Canada compared with 31% (222/724) and 16% (116/724) in other hics (p < 0.001 and p = 0.023 respectively). The median number of patients seen in a full-day clinic was 15 in Canada and 25 in other hics (p = 0.220). Canadian mos reported spending a median of 55 minutes per new consultation; new consultations of 35 minutes were reported in other hics (p < 0.001). Median hours worked per week was 55 in Canada and 45 in other hics (p = 0.200). Conclusions: Although the median annual clinical volume for Canadian mos aligns with recommended targets, half the respondents exceeded that level of activity. Health policymakers and educators have to consider mo workforce supply and alternative models of care in preparation for the anticipated surge in cancer incidence in the coming decade.

RESUMO

Background: Overuse of surveillance imaging in patients after curative treatment for early breast cancer (ebc) was recently identified as one of the Choosing Wisely Canada initiatives to improve the quality of cancer care. We undertook a population-level examination of imaging practices in Ontario as they existed before the launch of that initiative. Methods: Patients diagnosed with ebc between 2006 and 2010 in Ontario were identified from the Ontario Cancer Registry. Records were linked deterministically to provincial health care databases to obtain comprehensive follow-up. We identified all advanced imaging exams [aies: computed tomography (ct), bone scan, positron-emission tomography] and basic imaging exams (bies: ultrasonography, chest radiography) occurring within the first 2 years after curative treatment. Poisson regression was used to assess associations between patient or provider characteristics and the rate of aies. Results: Of 30,006 women with ebc, 58.6% received at least 1 bie, and 30.6% received at least 1 aie in year 1 after treatment. In year 2, 52.7% received at least 1 bie, and 25.7% received at least 1 aie. The most common aies were chest cts and bone scans. The rate of aies increased with older age, higher disease stage, comorbidity, chemotherapy exposure, and prior staging investigations (p < 0.001). Imaging was ordered mainly by medical oncologists (38%), followed by primary care physicians (23%), surgeons (13%), and emergency room physicians (7%). Conclusions: Despite recommendations against its use, imaging is common in ebc survivors. Understanding the factors associated with aie use helps to identify areas for further research and is required to lower imaging rates and to improve survivorship care.

RESUMO

AIMS: Although FOLFIRINOX is a standard treatment option for advanced pancreas cancer, there are few data describing utilisation and effectiveness in routine clinical practice. Here we report practice patterns and outcomes in the general population of Ontario, Canada. MATERIALS AND METHODS: Using the Ontario Cancer Registry and New Drug Funding Program, we identified all patients with pancreas cancer treated with palliative intent gemcitabine or FOLFIRINOX in Ontario during 2006-2014. FOLFIRINOX became available in Ontario's single-payer health system in November 2011. Gemcitabine cases were classified as pre-FOLFIRINOX era (2006-2010) or post-FOLFIRINOX era (2011-2014). Cases treated with perioperative chemotherapy were excluded. Comparisons of proportions between study groups were made using the chi-square test. Overall survival was measured from the date of chemotherapy initiation. RESULTS: During 2006-2014, 3826 patients in Ontario were treated with gemcitabine (n = 3042) or FOLFIRINOX (n = 784) chemotherapy for advanced pancreas cancer. Uptake of FOLFIRINOX increased from 41% (206/505) of treated cases in 2012 to 56% (274/486) of treated cases in 2014. The median overall survival of patients treated with gemcitabine was 5.0 months in 2006-2010 and 4.8 months in 2011-2014. The median overall survival of FOLFIRINOX patients treated in 2011-2014 was 8.2 months. CONCLUSION: The use of FOLFIRINOX in the general population has increased since 2011. Survival outcomes show a substantial efficacy-effectiveness gap between the pivotal Prodige 4/ACCORD 11 clinical trial and routine practice.

RESUMO

BACKGROUND: Documentation of advance care planning for patients with terminal cancer is known to be poor. Here, we describe a quality improvement initiative. METHODS: Patients receiving palliative chemotherapy for metastatic lung, pancreatic, colorectal, and breast cancer during 2010-2015 at the Cancer Centre of Southeastern Ontario were identified from electronic pharmacy records. Clinical notes were reviewed to identify documentation of care plans in the event of acute deterioration. After establishing baseline practice, we sought to improve documentation of goals of care and referral rates to palliative care. Using quality improvement methodology, we developed a guideline, a standardized documentation system, and a process to facilitate early referral to palliative care. RESULTS: During 2010-2015, 456 patients were included in the baseline cohort: 63% with lung cancer, 16% with colorectal cancer, 13% with pancreatic cancer, and 7% with breast cancer. Care goals in the event of an acute illness were documented by medical oncologists in 6% of cases (26 of 456). Of the 456 patients, 47% (n = 214) were seen by palliative care; care goals were documented by palliative care in 48% of the patients seen (103 of 214). With those baseline data in hand, a local practice guideline and process was developed to facilitate the identification of patients for whom advance care planning and early palliative care referral should be considered. A system was also established so that goals-of-care documentation will be supported with a written framework and broadly accessible in the electronic medical record. CONCLUSIONS: Low rates of documentation of advance care planning and referral to palliative care persist and have stimulated a local quality improvement initiative.

RESUMO

BACKGROUND: Although high-dose interferon (hd-ifn) is the sole approved adjuvant systemic treatment for melanoma in many jurisdictions, it is toxic. We sought to assess the population-level effects of hd-ifn toxicity, particularly neuropsychiatric toxicity, hypothesizing that such toxicity would have the greatest effect on mental health services use in advanced resected melanoma. METHODS: This retrospective population-based registry study considered all melanoma patients receiving adjuvant hd-ifn in Ontario during 2008-2012. Toxicity was investigated through health services use compatible with hd-ifn toxicity (for example, mental health physician billings). Using stage data reported from cancer centres about a subset of patients (stages iib-iiic), a propensity-matched analysis compared such service use in patients who did and did not receive hd-ifn. Associations between early hd-ifn discontinuation and health services use were examined. RESULTS: Of 718 melanoma patients who received hd-ifn, 12% were 65 years of age and older, and 83% had few or no comorbidities. One third of the patients experienced 1 or more toxicity-associated health care utilization events within 1 year of starting hd-ifn. Of 420 utilization events, 364 (87%) were mental health-related, with 54% being family practitioner visits, and 39% being psychiatrist visits. In the propensity-matched analysis, patients receiving hd-ifn were more likely than untreated matched controls to use a mental health service (p = 0.01), with 42% of the control group and 51% of the hd-ifn group using a mental health service in the period spanning the 12 months before to the 24 months after diagnosis. In the multivariable analysis, early drug discontinuation was more likely in the presence of pre-existing mental health issues (odds ratio: 2.0; 95% confidence limits: 1.1, 3.4). CONCLUSIONS: Stage iib-iiic melanoma patients carry a substantial burden of mental health services use whether or not receiving hd-ifn, highlighting an important survivorship issue for these patients. High-dose interferon is associated with more use of mental health services, and pre-treatment use of mental health services is associated with treatment discontinuation. That association should be kept in mind when hd-ifn is being considered.

RESUMO

INTRODUCTION: The rising cost of healthcare requires rethinking in terms of resource utilisation care delivery. Nurse-led PSA phone follow-up clinics may provide a suitable option. MATERIALS AND METHODS: 815 patients were recruited for the nurse-led stable prostate cancer telephone follow-up service. A convenience sample was selected for postal questionnaire assessment of their satisfaction. RESULTS: 815 patients had 3683 phone-call follow ups over 10 years. Patients' own understanding of condition varied from average (76.3%) and good (9.2%) in the majority. 87.2% found the service convenient and 75.6% informative. 95.3% found the telephone assessment preferable to attending the outpatient department. 87.2% were keen on savings on transport/travel. 53.5% found it more reassuring. 91.9% of patients felt that everything they wanted to talk about was covered. DISCUSSION: This service can be delivered in a high volume nurse-led service, with high levels of patient satisfaction, as an innovative service development.

RESUMO

AIMS: Bladder-sparing radiotherapy for muscle-invasive bladder cancer (MIBC) may be underutilised in North America. To understand factors driving practice we used the Theoretical Domains Framework (TDF) to identify barriers and enablers of bladder-sparing radiotherapy utilisation. MATERIALS AND METHODS: A convenience sample of Canadian urologists, medical oncologists and radiation oncologists participated in individual semi-structured 1 h interviews. An interview guide was developed using the TDF to assess barriers and enablers of bladder-sparing radiotherapy use. Interviews were recorded and transcribed. Two investigators independently identified barriers and enablers and assigned them to specific themes. Participant recruitment continued until saturation. RESULTS: In total, 71 physicians were invited to participate and 34 (48%) agreed to be interviewed; 13 urologists, 11 radiation oncologists and 10 medical oncologists. We identified the following barriers to the use of bladder-sparing radiotherapy (relevant TDF domains in parentheses): (1) beliefs that radiotherapy has inferior survival compared with cystectomy (beliefs about consequences); (2) lack of referral from urology to radiation oncology (behavioural regulation; memory, attention and decision-making); (3) lack of 'champions' who advocate for radiotherapy (social and professional role); and (4) inadequate multidisciplinary collaboration (environmental context and resources). Predominant enablers to the use of bladder-sparing radiotherapy included: (1) 'champions' who believe in the value of radiotherapy (social and professional role); (2) beliefs by urologists that radiation oncologists should present radiotherapy options to all patients (social and professional role); (3) institutional policy that all MIBC patients should be seen by multiple specialists (environmental context and resources); (4) system facilitators of radiation oncology referral (i.e. nurse navigator) (environmental context and resources); and (5) patient-driven consultations seeking alternatives to cystectomy (social influences). CONCLUSIONS: These findings identify important barriers and enablers to the use of bladder-sparing radiotherapy in MIBC. Physician beliefs, access to multidisciplinary care and institutional context should be considered in efforts to increase the use of bladder-sparing radiotherapy.
