The burden of cancer for Canadian citizens and society is large. New technologies have the potential to increase the use of genetic information in clinical decision-making, furthering prevention, surveillance, and safer, more effective drug therapies for cancer patients. Personalized medicine can have different meanings to different people. The context for personalized medicine in the present paper is genetic testing, which offers the promise of refining treatment decisions for those diagnosed with chronic and life-threatening illnesses. Personalized medicine and genetic characterization of tumours can also give direction to the development of novel drugs. Genetic testing will increasingly become an essential part of clinical decision-making. In Canada, provinces are responsible for health care, and most have unique policies and programs in place to address cancer control. The result is inconsistency in access to and delivery of therapies and other interventions, beyond the differences expected because of demographic factors and clinical education. Inconsistencies arising from differences in resources, policy, and application of evidence-informed personalized cancer medicine exacerbate patient access to appropriate testing and quality care. Geographic variations in cancer incidence and mortality rates in Canada-with the Atlantic provinces and Quebec having higher rates, and British Columbia having the lowest rates-are well documented. Our purpose here is to provide an understanding of current and future applications of personalized medicine in oncology, to highlight the benefits of personalized medicine for patients, and to describe issues and opportunities for improvement in the coordination of personalized medicine in Canada. Efficient and more rapid adoption of personalized medicine in oncology in Canada could help overcome those issues and improve cancer prevention and care. That task might benefit from the creation of a National Genetics Advisory Panel that would review research and provide recommendations on tests for funding or reimbursement, guidelines, service delivery models, laboratory quality assurance, education, and communication. More has to be known about the current state of personalized cancer medicine in Canada, and strategies have to be developed to inform and improve understanding and appropriate coordination and delivery. Our hope is that the perspectives emphasized in this paper will stimulate discussion and further research to create a more informed response.
加拿大公民和社会的癌症负担很大。新技术有可能增加在临床决策中使用遗传信息,从而进一步促进癌症患者的预防、监测以及更安全、更有效的药物治疗。个性化医学对不同的人可能有不同的含义。本文中个性化医学的背景是基因检测,它为那些被诊断患有慢性和危及生命的疾病的人提供了精确治疗决策的希望。个性化医学和肿瘤的遗传特征也可以为新型药物的开发指明方向。基因检测将越来越成为临床决策的重要组成部分。在加拿大,各省负责医疗保健,大多数省都有独特的政策和方案来控制癌症。其结果是,在治疗和其他干预措施的可及性和提供方面存在不一致,这超出了由于人口因素和临床教育而预期的差异。由于资源、政策和应用循证个性化癌症医学方面的差异而导致的不一致,使患者获得适当检测和高质量护理的机会受到影响。加拿大的癌症发病率和死亡率存在明显的地域差异——大西洋省份和魁北克省的发病率较高,而不列颠哥伦比亚省的发病率较低——这一点已得到充分证明。我们在这里的目的是提供对肿瘤学中个性化医学的当前和未来应用的理解,突出个性化医学对患者的益处,并描述在加拿大协调个性化医学方面的问题和机会。在加拿大,肿瘤学中个性化医学的更高效和更快速采用可以帮助克服这些问题,并改善癌症的预防和护理。为了实现这一目标,可能需要创建一个国家遗传咨询小组,该小组将审查研究,并就资助或报销、指南、服务提供模式、实验室质量保证、教育和沟通方面的测试提供建议。需要更多地了解加拿大个性化癌症医学的现状,并制定战略,以提高对协调和提供的理解和适当性。我们希望本文强调的观点将激发讨论和进一步研究,以创建更明智的应对措施。
