Projected estimates of cancer in Canada in 2024.

BACKGROUND: Cancer surveillance data are essential to help understand where gaps exist and progress is being made in cancer control. We sought to summarize the expected impact of cancer in Canada in 2024, with projections of new cancer cases and deaths from cancer by sex and province or territory for all ages combined. METHODS: We obtained data on new cancer cases (i.e., incidence, 1984-2019) and deaths from cancer (i.e., mortality, 1984-2020) from the Canadian Cancer Registry and Canadian Vital Statistics Death Database, respectively. We projected cancer incidence and mortality counts and rates to 2024 for 23 types of cancer, overall, by sex, and by province or territory. We calculated age-standardized rates using data from the 2011 Canadian standard population. RESULTS: In 2024, the number of new cancer cases and deaths from cancer are expected to reach 247 100 and 88 100, respectively. The age-standardized incidence rate (ASIR) and mortality rate (ASMR) are projected to decrease slightly from previous years for both males and females, with higher rates among males (ASIR 562.2 per 100 000 and ASMR 209.6 per 100 000 among males; ASIR 495.9 per 100 000 and ASMR 152.8 per 100 000 among females). The ASIRs and ASMRs of several common cancers are projected to continue to decrease (i.e., lung, colorectal, and prostate cancer), while those of several others are projected to increase (i.e., liver and intrahepatic bile duct cancer, kidney cancer, melanoma, and non-Hodgkin lymphoma). INTERPRETATION: Although the overall incidence of cancer and associated mortality are declining, new cases and deaths in Canada are expected to increase in 2024, largely because of the growing and aging population. Efforts in prevention, screening, and treatment have reduced the impact of some cancers, but these short-term projections highlight the potential effect of cancer on people and health care systems in Canada.

A trans-Canadian positive deviance seminar for paraesophageal hernia surgery: Reporting national postoperative outcomes and consensus recommendations.

BACKGROUND: The incidence of adverse events (AEs) and length of stay (LOS) varies significantly following paraesophageal hernia surgery. We performed a Canadian multicenter positive deviance (PD) seminar to review individual center and national level data and establish holistic perioperative practice recommendations. METHODS: A national virtual PD seminar was performed in October 2021. Recent best evidence focusing on AEs and LOS was presented. Subsequently, anonymized center-level AE and LOS data collected between 01/2017 and 01/2021 from a prospective, web-based database that tracks postoperative outcomes was presented. The top two performing centers with regards to these metrics were chosen and surgeons from these hospitals discussed elements of their treatment pathways that contributed to these outcomes. Consensus recommendations were then identified with participants independently rating their level of agreement. RESULTS: Twenty-eight surgeons form 8 centers took part in the seminar across 5 Canadian provinces. Of the 680 included patients included, Clavien-Dindo grade I and II/III/IV/V complications occurred in 121/39/12/2 patients (17.8%/5.7%/1.8%/0.3%). Respiratory complications were the most common (effusion 12/680, 1.7% and pneumonia 9/680, 1.3%). Esophageal and gastric perforation occurred in 7 and 4/680, (1.0% and 0.6% respectively). Median LOS varied significantly between institutions (1 day, range 1-3 vs. 7 days, 3-8, p < 0.001). A strong level of agreement was achieved for 10/12 of the consensus statements generated. CONCLUSION: PD seminars provide a supportive forum for centers to review best evidence and experience and generate recommendations based on expert opinion. Further research is ongoing to determine if this approach effectively accomplishes this objective.

Recommendations to Improve Management of Incidental Pulmonary Nodules in Canada: Expert Panel Consensus.

Introduction: Incidental pulmonary nodules (IPN) are common radiologic findings, yet management of IPNs is inconsistent across Canada. This study aims to improve IPN management based on multidisciplinary expert consensus and provides recommendations to overcome patient and system-level barriers. Methods: A modified Delphi consensus technique was conducted. Multidisciplinary experts with extensive experience in lung nodule management in Canada were recruited to participate in the panel. A survey was administered in 3 rounds, using a 5-point Likert scale to determine the level of agreement (1 = extremely agree, 5 = extremely disagree). Results: Eleven experts agreed to participate in the panel; 10 completed all 3 rounds. Consensus was achieved for 183/217 (84.3%) statements. Panellists agreed that radiology reports should include a standardized summary of findings and follow-up recommendations for all nodule sizes (ie, <6, 6-8, and >8 mm). There was strong consensus regarding the importance of an automated system for patient follow-up and that leadership support for organizational change at the administrative level is of utmost importance in improving IPN management. There was no consensus on the need for standardized national referral pathways, development of new guidelines, or establishing a uniform picture archiving and communication system. Conclusion: Canadian IPN experts agree that improved IPN management should include standardized radiology reporting of IPNs, standardized and automated follow-up of patients with IPNs, guideline adherence and implementation, and leadership support for organizational change. Future research should focus on the implementation and long-term effectiveness of these recommendations in clinical practice.

The short and long-term effects of open vs minimally invasive thymectomy in myasthenia gravis patients: a systematic review and meta-analysis.

OBJECTIVE: Thymectomy has been utilized as a treatment for Myasthenia Gravis (MG) for many decades, with both open and minimally invasive surgical (MIS) techniques currently used. Although MIS has shown improved short-term results, long-term effects remain uncertain. This systematic review and meta-analysis aim to compare the post-operative and long-term outcomes of MIS versus open thymectomy in MG patients. METHODS: MEDLINE, EMBASE and CENTRAL databases were searched from inception till January 2022 for keywords related to MG and open or MIS thymectomy. Primary outcome was complete stable remission (CSR), and secondary outcomes were clinical improvement, complications, length of stay, operation time, and blood loss. Grading of recommendations, assessment, development, and evaluation was used to assess the certainty of evidence. RESULTS: 26 studies with 3588 patients were included in the analysis. At 1, 3 and 5 years, there was no statistical difference noted in CSR between open versus MIS thymectomy. However, CSR was improved at 1 year for MIS thymectomy in non-thymomatous MG (P = 0.03). There was no significant difference in rates of partial clinical improvement between techniques at 1-year. Although analyses on length of hospital stay and blood loss showed improvement following MIS thymectomy, operative time was shorter for open thymectomy. CONCLUSION: This is the first systematic review and meta-analysis assessing long-term effects of MIS versus open thymectomy in MG patients. Given the lack of significant differences noted, either MIS or open thymectomy can be performed, based on surgeon preference. Further high-level, long-term research should be conducted to determine the benefit of each technique.

The fragility of significant results from randomized controlled trials in esophageal surgeries.

While randomized controlled trials (RCTs) are regarded as one of the highest forms of clinical research, the robustness of their P values can be difficult to ascertain. Defined as the minimum number of patients in a study arm that would need to be changed from a non-event to event for the findings to lose significance, the Fragility Index is a method for evaluating results from these trials. This study aims to calculate the Fragility Index for trials evaluating perioperative esophagectomy-related interventions to determine the strength of RCTs in this field. MEDLINE and EMBASE were searched for RCTs related to esophagectomy that reported a significant dichotomous outcome. Two reviewers independently screened articles and performed the data extractions with risk of bias assessment. The Fragility Index was calculated using a two-tailed Fisher's exact test. Bivariate correlation was conducted to evaluate associations between the Fragility Index and study characteristics. 41 RCTs were included, and the median sample size was 80 patients [Interquartile range (IQR) 60-161]. Of the included outcomes, 29 (71%) were primary, and 12 (29%) were secondary. The median Fragility Index was 1 (IQR 1-3), meaning that by changing one patient from a non-event to event, the results would become non-significant. Fragility Index was correlated with P value, number of events, and journal impact factor. The RCTs related to esophagectomy did not prove to be robust, as the significance of their results could be changed by altering the outcome status of a handful of patients in one study arm.

Role of Adjuvant Therapy in Esophageal Cancer Patients After Neoadjuvant Therapy and Esophagectomy: A Systematic Review and Meta-analysis.

OBJECTIVE: The aim of this study was to analyze esophageal cancer patients who previously underwent neoadjuvant therapy followed by a curative resection to determine whether additional adjuvant therapy is associated with improved survival outcomes. SUMMARY BACKGROUND DATA: Neoadjuvant therapy followed by surgery is the standard of care for locally advanced esophageal cancer, whereas adjuvant therapy is typically employed for patients with residual disease. However, the role of adjuvant therapy after a curative resection is still uncertain. METHODS: MEDLINE, EMBASE, and CENTRAL databases were searched for studies comparing patients with esophageal cancer who underwent neoadjuvant therapy and curative resection with and without adjuvant therapy. Primary outcome was overall survival (OS), and random effects meta-analysis was conducted where appropriate. Grading of recommendations, assessment, development, and evaluation was used to assess the certainty of evidence. RESULTS: Ten studies involving 6462 patients were included. When compared to patients who received neoadjuvant therapy and esophagectomy alone, adjuvant therapy groups experienced a significant decrease in mortality by 48% at 1 year (Risk Ratio (RR) 0.52, 95% confidence interval [CI] 0.41-0.65, P < 0.001, moderate certainty). This reduction in mortality was carried through to 5-year follow-up (RR 0.91, 95% CI 0.86-0.96, P < 0.001, moderate certainty). The difference between the adjuvant therapy and the control group was uncertain regarding the secondary outcomes. CONCLUSION: Adjuvant therapy after neoadjuvant treatment and esophagectomy with negative resection margins provide an improved OS at 1 and 5 years with moderate to high certainty of evidence, but the benefit for disease-free survival and locoregional/distal recurrence remain uncertain due to limited reporting of these outcomes.

An International Consensus on Actions to Improve Lung Cancer Survival: A Modified Delphi Method Among Clinical Experts in the International Cancer Benchmarking Partnership.

BACKGROUND: Research from the International Cancer Benchmarking Partnership (ICBP) demonstrates that international variation in lung cancer survival persists, particularly within early stage disease. There is a lack of international consensus on the critical contributing components to variation in lung cancer outcomes and the steps needed to optimise lung cancer services. These are needed to improve the quality of options for and equitable access to treatment, and ultimately improve survival. METHODS: Semi-structured interviews were conducted with 9 key informants from ICBP countries. An international clinical network representing 6 ICBP countries (Australia, Canada, Denmark, England, Ireland, New Zealand, Northern Ireland, Scotland & Wales) was established to share local clinical insights and examples of best practice. Using a modified Delphi consensus model, network members suggested and rated recommendations to optimise the management of lung cancer. Calls to Action were developed via Delphi voting as the most crucial recommendations, with Good Practice Points included to support their implementation. RESULTS: Five Calls to Action and thirteen Good Practice Points applicable to high income, comparable countries were developed and achieved 100% consensus. Calls to Action include (1) Implement cost-effective, clinically efficacious, and equitable lung cancer screening initiatives; (2) Ensure diagnosis of lung cancer within 30 days of referral; (3) Develop Thoracic Centres of Excellence; (4) Undertake an international audit of lung cancer care; and (5) Recognise improvements in lung cancer care and outcomes as a priority in cancer policy. CONCLUSION: The recommendations presented are the voice of an expert international lung cancer clinical network, and signpost key considerations for policymakers in countries within the ICBP but also in other comparable high-income countries. These define a roadmap to help align and focus efforts in improving outcomes and management of lung cancer patients globally.

Projected estimates of cancer in Canada in 2022.

BACKGROUND: Regular cancer surveillance is crucial for understanding where progress is being made and where more must be done. We sought to provide an overview of the expected burden of cancer in Canada in 2022. METHODS: We obtained data on new cancer incidence from the National Cancer Incidence Reporting System (1984-1991) and Canadian Cancer Registry (1992-2018). Mortality data (1984-2019) were obtained from the Canadian Vital Statistics - Death Database. We projected cancer incidence and mortality counts and rates to 2022 for 22 cancer types by sex and province or territory. Rates were age standardized to the 2011 Canadian standard population. RESULTS: An estimated 233 900 new cancer cases and 85 100 cancer deaths are expected in Canada in 2022. We expect the most commonly diagnosed cancers to be lung overall (30 000), breast in females (28 600) and prostate in males (24 600). We also expect lung cancer to be the leading cause of cancer death, accounting for 24.3% of all cancer deaths, followed by colorectal (11.0%), pancreatic (6.7%) and breast cancers (6.5%). Incidence and mortality rates are generally expected to be higher in the eastern provinces of Canada than the western provinces. INTERPRETATION: Although overall cancer rates are declining, the number of cases and deaths continues to climb, owing to population growth and the aging population. The projected high burden of lung cancer indicates a need for increased tobacco control and improvements in early detection and treatment. Success in breast and colorectal cancer screening and treatment likely account for the continued decline in their burden. The limited progress in early detection and new treatments for pancreatic cancer explains why it is expected to be the third leading cause of cancer death in Canada.

Pan-Canadian colorectal cancer surgery data: an opportunity for reflection and improvement.

Variation in data provides an opportunity for health care providers to assess how patient care can be improved. Pan-Canadian colorectal cancer data show that, although long-term survival is similar among provinces, differences exist in other important aspects of care: length of stay, minimally invasive approach, readmission, and short-term mortality. Examining variation among stakeholders involved with colorectal cancer allows the opportunity to reflect on and optimize care.

Impact of the COVID-19 pandemic on non-small-cell lung cancer pathologic stage and presentation.

BACKGROUND: It is believed that the cessation of normative cancer care services during the COVID-19 pandemic may be resulting in pathologic upstaging and higher long-term mortality rates. We aimed to understand how the pandemic has affected our patients diagnosed with non-small-cell lung cancer (NSCLC). METHODS: We conducted a single-centre retrospective analysis to assess how the COVID-19 pandemic has affected patient referrals, pathologic stage of NSCLC, mortality rates and surgical procedures at our cancer care centre in Ontario, Canada. At our centre, physicians advocated for and followed recommendations that operations in cancer patients should be among the last procedures to be delayed. Patients were included if they were aged 18 years or older, were not receiving palliative care, and had been screened, diagnosed and treated for NSCLC (primary tumours). We compared outcomes between a prepandemic period (January 2019 to February 2020) and a period during the pandemic (March 2020 to February 2021). RESULTS: A total of 695 patients were included for statistical analysis, of whom 650 underwent surgery. There was no statistically significant difference in any of the outcomes of interest between patients seen before (n = 330) and during (n = 320) the pandemic. CONCLUSION: Cancer care services at our centre were maintained during the COVID-19 pandemic, and potential adverse effects on prognosis and survival that have been seen in other countries were avoided. The results inform health care providers how the effects of future pandemics can be blunted by using proactive preservative strategies and surgeon advocacy.

Outcomes of patients discharged home with a chest tube after lung resection: a multicentre cohort study.

BACKGROUND: Prolonged air leaks are increasingly treated in the outpatient setting, with patients discharged with chest tubes in place. We evaluated the incidence and risk factors associated with readmission, empyema development and further interventions in this patient population. METHODS: We undertook a retrospective cohort analysis of all patients from 4 tertiary academic centres (January 2014 to December 2017) who were discharged home with a chest tube after lung resection for a postoperative air leak lasting more than 5 days. We analyzed demographics, patient factors, surgical details, hospital readmission, reintervention, antibiotics at discharge, empyema and death. RESULTS: Overall, 253 of 2794 patients were analyzed (9.0% of all resections), including 30 of 759 from centre 1 (4.0%), 67 of 857 from centre 2 (7.8%), 9 of 247 from centre 3 (3.6%) and 147 of 931 from centre 4 (15.8%) (p < 0.001). Our cohort consisted of 56.5% men, and had a median age of 69 (range 19-88) years. Despite similar initial lengths of stay (p = 0.588), 49 patients (19.4%) were readmitted (21%, 0%, 23% and 11% from centres 1 to 4, respectively, p = 0.029), with 18 (36.7%) developing empyema, 11 (22.4%) requiring surgery and 3 (6.1%) dying. Only chest tube duration was a significant predictor of readmission (p < 0.001) and empyema development (p = 0.003), with a nearly threefold increased odds of developing empyema when the chest tube remained in situ for more than 20 days. CONCLUSION: Discharge with chest tube after lung resection is associated with serious adverse events. Given the high risk of empyema development, removal of chest tubes should be considered, when appropriate, within 20 days of surgery. Our data suggest a potential need for proactive postdischarge outpatient management programs to diminish risk of morbidity and death.

Can a mobile app technology reduce emergency department visits and readmissions after lung resection? A prospective cohort study.

BACKGROUND: Emergency department (ED) visits and readmissions after thoracic surgery are a major health care problem. We hypothesized that the addition of a novel post-discharge mobile app specific to thoracic surgery to an existing home care program would reduce ED visits and readmissions compared to a home care program alone. METHODS: We conducted a prospective cohort study of patients undergoing major lung resection for malignant disease between November 2016 and May 2018. Patients received either home care alone (control group) or home care plus a patient-input mobile app (intervention group). Primary outcomes were 30-day readmission and ED visit rates. Secondary outcomes included reasons for ED visits and readmissions, perioperative complications, 30-day mortality, anxiety (assessed with the Generalized Anxiety Disorder-7 Scale [GAD-7]) and app-related adverse events. We compared outcomes between the 2 groups, analyzing the data on an intention-to-treat basis. RESULTS: Despite the greater number of open surgery and anatomic resections in the intervention cohort, patients in that group were less likely than those in the control group to visit the ED within 30 days of discharge (24.0% v. 38.8%, p = 0.02). Thirty-day readmission rates were similar between the intervention and control groups (10.1% v. 12.2%, p = 0.6). In a subset of patients, there was no difference between the 2 groups in the proportion of patients with a GAD-7 score of 0 (control group 79.8%, intervention group 79.5%, p = NS), which indicated a similar absence of postdischarge anxiety and depression symptoms in the 2 cohorts. CONCLUSION: The addition of a mobile app to a home care program after thoracic surgery was associated with a reduced frequency of ED visits, in spite of the higher proportions of thoracotomies and anatomic resections in the app cohort. More studies are needed to evaluate the full effect of this new, emerging technology.

International trends in oesophageal cancer survival by histological subtype between 1995 and 2014.

INTRODUCTION: Survival from oesophageal cancer remains poor, even across high-income countries. Ongoing changes in the epidemiology of the disease highlight the need for survival assessments by its two main histological subtypes, adenocarcinoma (AC) and squamous cell carcinoma (SCC). METHODS: The ICBP SURVMARK-2 project, a platform for international comparisons of cancer survival, collected cases of oesophageal cancer diagnosed 1995 to 2014, followed until 31st December 2015, from cancer registries covering seven participating countries with similar access to healthcare (Australia, Canada, Denmark, Ireland, New Zealand, Norway and the UK). 1-year and 3-year age-standardised net survival alongside incidence rates were calculated by country, subtype, sex, age group and period of diagnosis. RESULTS: 111 894 cases of AC and 73 408 cases of SCC were included in the analysis. Marked improvements in survival were observed over the 20-year period in each country, particularly for AC, younger age groups and 1 year after diagnosis. Survival was consistently higher for both subtypes in Australia and Ireland followed by Norway, Denmark, New Zealand, the UK and Canada. During 2010 to 2014, survival was higher for AC compared with SCC, with 1-year survival ranging from 46.9% (Canada) to 54.4% (Ireland) for AC and 39.6% (Denmark) to 53.1% (Australia) for SCC. CONCLUSION: Marked improvements in both oesophageal AC and SCC survival suggest advances in treatment. Less marked improvements 3 years after diagnosis, among older age groups and patients with SCC, highlight the need for further advances in early detection and treatment of oesophageal cancer alongside primary prevention to reduce the overall burden from the disease.

A novel online education module to teach clinicians how to correctly identify ultrasonographic features of mediastinal lymph nodes during endobronchial ultrasound

Background: Ultrasonographic features can be used to predict mediastinal lymph node malignancy during endobronchial ultrasonography. Despite the validity of using these features for this purpose, the features are not being widely used in clinical practice. This may be attributable to the absence of educational programs that teach clinicians how to identify the features. To address this knowledge gap, we developed an online educational module to teach clinicians how to correctly interpret ultrasonographic features. Methods: The module was designed using corrective feedback and test-enhanced learning theories and distributed to clinicians in relevant specialties. The efficacy of the program was determined by comparing the percentages of correctly identified ultrasonographic features as each clinician progressed through the module. Participants were also asked to self-rate their confidence during the module. Analysis of variance was conducted, and a learning curve and descriptive statistics were generated. Results: Twenty-two of the 29 participants (76%) completed the module. Analysis of variance indicated that the percentage of correctly identified features increased significantly as clinicians completed the module (p = 0.004); this finding is supported by the positive slope of the learning curve. Even though they initially reported some difficulty with identifying certain features, their confidence increased as they progressed through the module. When asked, 86% of participants reported that they found the educational module helpful and 90% reported that they would recommend it to others. Conclusion: Participating clinicians were receptive to the interactive educational module. It enhances clinician skill and confidence in interpreting ultrasonographic features. The results of this study provide the foundation needed to test the validity of the educational module in clinical settings and to further explore clinician preferences for educational programs.

Contexte: Les caractéristiques échographiques permettent de prédire la malignité des ganglions lymphatiques médiastinaux durant l'échographie endobronchique. Malgré leur validité à cette fin, ces caractéristiques ne sont pas très utilisées dans la pratique clinique. Cela pourrait être attribuable à l'absence de programmes de formation pour enseigner aux médecins comment repérer ces caractéristiques. Pour répondre à cette lacune au plan des connaissances, nous avons conçu un module de formation en ligne pour enseigner aux médecins comment interpréter correctement les caractéristiques échographiques. Méthodes: Le module a été conçu selon les théories de rétroaction corrective et d'apprentissage par test et a été distribué aux médecins des spécialités concernées. L'efficacité du programme a été déterminée en comparant les pourcentages de caractéristiques échographiques correctement identifiées à mesure que chaque médecin progressait d'une étape à l'autre du module. Les participants ont aussi été invités à autoévaluer leur degré de confiance pendant la réalisation du module. On a ensuite procédé à une analyse de la variance et on a généré une courbe d'apprentissage et des statistiques descriptives. Résultats: Vingt-deux participants sur 29 (76 %) ont mené le module à terme. L'analyse de la variance a indiqué que le pourcentage de caractéristiques correctement identifiées augmentait significativement à mesure que les médecins finalisaient leur module (p = 0,004); cette observation est confirmée par la courbe d'apprentissage positive. Même s'ils avaient initialement fait état de certaines difficultés à identifier des caractéristiques, leur degré de confiance a augmenté au fur et à mesure qu'ils avançaient. Quatre-vingt-six pour cent des participants ont indiqué avoir trouvé le module utile et 90 % ont dit qu'ils le recommanderaient. Conclusion: Les médecins participants ont bien accueilli ce module éducatif interactif : il améliore les habiletés et le degré de confiance des médecins en leur capacité d'interpréter les caractéristiques échographiques. Les résultats de cette étude servent de point de départ pour tester la validité du module en milieu clinique et pour continuer d'explorer les préférences des médecins en ce qui concerne les programmes de formation.

Guidance for management of cancer surgery during the COVID-19 pandemic.

Summary: During the coronavirus disease 2019 (COVID-19) pandemic, delaying lifesaving cancer surgeries must be done with extreme caution and thoughtfulness. Modelling indicates that delays in high-risk cancer surgeries beyond 6 weeks could affect long-term outcomes for thousands of Canadians. Consequently, it is possible that postponing cancer surgery without consideration of its implications could cost more lives than can be saved by diverting all surgical resources to COVID-19. This article provides general guidance on supporting curative surgical treatment where appropriate and with available resources.

Trends in Survival Based on Treatment Modality in Non-Small Cell Lung Cancer Patients: A Population-Based Study.

Objectives: We examined the trends in survival based on treatment modality among non-small cell lung cancer (NSCLC) patients in the province of Ontario, Canada, from 2007 to 2015. Methods: We investigated the trends in survival based on treatment modality. Results: Among 56,417 identified patients, the mean age at diagnosis was 70.1 years (SD = 10.7). Treatment modalities varied significantly over time (p<.001). Overall, 23.0% of patients received surgical treatments. We observed more than 20% increase in five-year survival rates for all surgical groups over time. Conclusions: Patients undergoing sublobar/lobar resections had higher survival rate.

Projection du fardeau du cancer au Canada en 2024.

CONTEXTE: Les données de surveillance du cancer sont essentielles pour mieux comprendre les lacunes et les progrès réalisés dans la lutte contre le cancer. Nous avons cherché à résumer les répercussions prévues du cancer au Canada en 2024, en effectuant des projections sur les nouveaux cas de cancer et les décès par cancer, par sexe et par province ou territoire, pour tous les âges confondus. MÉTHODES: Nous avons obtenu les données sur les nouveaux cas de cancer (c.-à-d., l'incidence, 1984­2019) et les décès par cancer (c.-à-d., la mortalité, 1984­2020) du Registre canadien du cancer et de la Base canadienne de données de l'état civil ­ Décès, respectivement. Nous avons projeté les chiffres et les taux d'incidence du cancer et de mortalité jusqu'en 2024 pour 23 types de cancer, par sexe et par province ou territoire. Nous avons calculé des taux normalisés selon l'âge au moyen de données de la population type canadienne de 2011. RÉSULTATS: En 2024, les nombres de nouveaux cas de cancer et de décès causés par le cancer devraient atteindre 247 100 et 88 100, respectivement. Le taux d'incidence normalisé selon l'âge (TINA) et le taux de mortalité normalisé selon l'âge (TMNA) devraient diminuer légèrement par rapport aux années précédentes, tant chez les hommes que chez les femmes, avec des taux plus élevés chez les hommes (TINA de 562,2 pour 100 000, et TMNA de 209,6 pour 100 000 chez les hommes; TINA de 495,9 pour 100 000 et TMNA de 152,8 pour 100 000 chez les femmes). Les TINA et les TMNA de plusieurs cancers courants devraient continuer à diminuer (p. ex., cancer du poumon, cancer colorectal et cancer de la prostate), tandis que ceux de plusieurs autres cancers devraient augmenter (p. ex., cancer du foie et des voies biliaires intrahépatiques, cancer du rein, mélanome et lymphome non hodgkinien). INTERPRÉTATION: Bien que l'incidence globale du cancer et la mortalité connexe sont en déclin, il devrait y avoir une augmentation des nouveaux cas et des décès au Canada en 2024, en grande partie en raison de la croissance et du vieillissement de la population. Les efforts en matière de prévention, de dépistage et de traitement ont atténué les répercussions de certains cancers, mais ces projections à court terme soulignent l'effet potentiel du cancer sur les gens et les systèmes de soins de santé au Canada.

Pan-Canadian standards for cancer surgery

About the Canadian Partnership Against Cancer: The Canadian Partnership Against Cancer (CPAC) is an independent organization funded by the federal government to accelerate action on cancer control for all Canadians. As the steward of the Canadian Strategy for Cancer Control (the Strategy), the Partnership works with Canada's cancer community to take action to ensure fewer people get cancer, more people survive cancer and those living with the disease have a better quality of life. This work is guided by the Strategy, which was refreshed for 2019 to 2029, and will help drive measurable change for all Canadians affected by cancer. The Strategy includes 5 priorities that will tackle the most pressing challenges in cancer control as well as distinct First Nations, Inuit and Métis Peoples­specific priorities and actions reflecting Canada's commitment to reconciliation. A specific action in the Strategy calls for reducing the differences in practice and service delivery by setting standards for high-quality care and promoting their adoption. The CPAC will oversee the implementation of the priorities in collaboration with organizations and individuals on the front lines of cancer care: the provinces and territories; health care professionals; people living with cancer and those who care for them; First Nations, Inuit and Métis communities; governments and organizations; and its funder, Health Canada.

Survey of Postoperative Regional Analgesia for Thoracoscopic Surgeries in Canada.

OBJECTIVES: To determine the preferences and perceptions regarding analgesic options for video-assisted thoracic surgery (VATS) among thoracic anesthesiologists in Canada. DESIGN: A cross-sectional survey of thoracic anesthesiologists with 30 multiple choice questions was e-mailed through an online survey tool called FluidSurveys was performed to members of the Canadian Anesthesiologists' Society. SETTING: A nationwide survey. PARTICIPANTS: Members of Canadian Anesthesiologists' Society who provide thoracic anesthesia INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Participant characteristics and outcomes are described using counts and percentages. The frequency of use of each technique for each surgical category is described in percentages and 95% confidence intervals. Based on the responses obtained from individual centers, approximately 469 anesthesiologists provided thoracic care in Canada at the time of the survey. The response rate to the survey was 19% (n = 89). Epidural analgesia was preferred by 93.42% (95% CI 85-98) for open surgeries compared with 41% (30-52) for VATS lobectomies. The difference was statistically significant-52% (37-67). Patient-controlled analgesia was preferred by 27% (19-39) for VATS lobectomies and 46% (35-57) for VATS minor resections. Only 14% preferred paravertebral block for any VATS surgeries. CONCLUSIONS: The use of analgesic techniques for VATS surgeries is variable and largely dictated by provider preferences. The majority still prefer epidural analgesia compared with paravertebral catheter (placed either by the anesthesiologist or surgeon). A broadly acceptable choice that is effective, safe, and technically less demanding requires comparative effectiveness studies and more uniform training for physicians.
