Cancer is a major morbidity and mortality concern in Malaysia. Based on National Cancer Registry data, the Malaysian population is estimated to bear a cancer burden of about 40,000 new cases per year, and a cumulative lifetime risk of about 1:4. Cancer research in Malaysia has to consider needs relevant to our population, and resources constraints. Hence, funding bodies prioritise cancers of high prevalence, unique to our community and posing specific clinical problems. Cancer diagnosis is crucial to cancer management. While cancer diagnosis research largely aims at improvements in diagnostic information towards more appropriate therapy, it also impacts upon policy development and other areas of cancer management. The scope of cancer diagnosis upon which this paper is based, and their possible impact on other R&D areas, has been broadly categorized into: (1) identification of aetiological agents and their linkages to the development of precancer and cancer (impact on policy development, cancer prevention and treatment), (2) cancer biology and pathogenesis (impact on cancer prevention, treatment strategies and product development), (3) improvements in accuracy, sensitivity and specificity in cancer detection, monitoring and classification (impact on technology development) and (4) prognostic and predictive parameters (impact on treatment strategies). This paper is based on data collected by the Working Group on Cancer Diagnosis Research for the First National Conference on Cancer Research Coordination in April 2004. Data was collated from the databases of Institutions/Universities where the authors are employed, the Ministry of Science, Technology and Innovation (MOSTI) and targeted survey feedback from key cancer researchers. Under the 7th Malaysia Plan, 76 cancer projects were funded through the Intensified Research in Priority Areas (IRPA) scheme of MOSTI, amounting to almost RM15 million of grant money. 47(61.8%) of these projects were substantially in cancer diagnosis, accounting for 65.6% (RM 9.7 million) of cancer project funds. The 8th Malaysia Plan saw a change in research strategy. The IRPA agency fielded several top-down projects which encouraged a multicentre and multidisciplinary approach. This resulted in larger funding per project i.e. RM32 million for 49 projects. There was also a surge of interest in drug development and natural products. Because of this shift in direction, cancer diagnosis projects constituted only 51% of IRPA-funded cancer projects. Nonetheless funding for cancer diagnosis research has exceeded that of the 7th Malaysia Plan, being RM12.5 million by March 2004. The majority of such research is carried out at the Universities, engaging a large number of young scientists and postgraduate students (51 MSc and 21 PhD). A lot of research findings presented at scientific meetings have not yet been published and there is a glaring shortage of patents and commercialization of research findings (such as creation of test kits). Because diagnosis is very much a part of clinical practice, many researchers felt satisfied and confident that their work will be translated into practice and will significantly improve diagnostic services in Malaysia. National guidelines and consensus development on at least three malignancies i.e. breast cancer, oral cancer and lymphoma, have substantial basis in local R&D work. Problems encountered in research included (1) insufficient funding to realize research objectives, (2) lack of local expertise (most research assistants are inexperienced BSc graduates with no or minimal research experience), (3) inadequate technical support from vendors during equipment failure, (4) inexperienced Institutional development units to assist in product development, (5) lack of venture capital for commercialization of findings, and (6) inadequate incentives to undertake research. Researchers pointed out that plans to promote research should include the establishment of (1) regional and national cancer tissue banks, (2) a National Cancer Research Institute, (3) a dedicated cancer research fund, (4) a registry of cancer researchers, (5) national research coordinators, (6) improved coverage by the National Cancer Registry, (7) more international collaboration, (8) a better career structure for researchers, (9) improved Institutional support for product realization, and (10) better recognition for cancer researchers.
癌症是马来西亚主要的发病和死亡原因。根据国家癌症登记处的数据,马来西亚人口估计每年承受约40000例新癌症病例的负担,累积终生风险约为1:4。马来西亚的癌症研究必须考虑与我国人口相关的需求以及资源限制。因此,资助机构优先考虑在我国社区中高发、独特且带来特定临床问题的癌症。癌症诊断对癌症管理至关重要。虽然癌症诊断研究主要旨在改进诊断信息以实现更恰当的治疗,但它也对政策制定和癌症管理的其他领域产生影响。本文所基于的癌症诊断范围及其对其他研发领域可能产生的影响,大致可分为:(1)确定病因及其与癌前病变和癌症发展的联系(对政策制定、癌症预防和治疗的影响),(2)癌症生物学和发病机制(对癌症预防、治疗策略和产品开发的影响),(3)提高癌症检测、监测和分类的准确性、敏感性和特异性(对技术开发的影响)以及(4)预后和预测参数(对治疗策略的影响)。本文基于癌症诊断研究工作组为2004年4月召开的第一届全国癌症研究协调会议收集的数据。数据来自作者所在机构/大学的数据库、科学、技术和创新部(MOSTI)以及关键癌症研究人员的定向调查反馈。在第七个马来西亚计划下,通过MOSTI的优先领域强化研究(IRPA)计划资助了76个癌症项目,拨款近1500万马来西亚林吉特。其中47个(61.8%)项目主要涉及癌症诊断,占癌症项目资金的65.6%(970万马来西亚林吉特)。第八个马来西亚计划见证了研究策略的转变。IRPA机构推出了几个自上而下的项目,鼓励采用多中心和多学科方法。这导致每个项目获得的资金更多,即49个项目获得3200万马来西亚林吉特。对药物开发和天然产品的兴趣也激增。由于这种方向转变,癌症诊断项目仅占IRPA资助的癌症项目的51%。尽管如此,癌症诊断研究的资金已超过第七个马来西亚计划,到2004年3月达到1250万马来西亚林吉特。此类研究大多在大学进行,吸引了大量年轻科学家和研究生(51名理学硕士和21名博士)。在科学会议上展示的许多研究结果尚未发表,而且研究结果的专利和商业化(如创建检测试剂盒)明显不足。由于诊断在很大程度上是临床实践的一部分,许多研究人员对他们的工作将转化为实践并将显著改善马来西亚的诊断服务感到满意和有信心。关于至少三种恶性肿瘤即乳腺癌、口腔癌和淋巴瘤的国家指南和共识制定在当地研发工作中有坚实基础。研究中遇到的问题包括:(1)资金不足无法实现研究目标,(2)缺乏当地专业知识(大多数研究助理是经验不足的理学学士毕业生,没有或只有极少研究经验),(3)设备故障时供应商提供的技术支持不足,(4)机构开发单位缺乏经验无法协助产品开发,(5)缺乏用于研究结果商业化的风险资本,以及(6)进行研究的激励措施不足。研究人员指出,促进研究的计划应包括建立:(1)区域和国家癌症组织库,(2)国家癌症研究所,(3)专门的癌症研究基金,(4)癌症研究人员登记册,(5)国家研究协调员,(6)扩大国家癌症登记处的覆盖范围,(7)更多国际合作,(8)为研究人员提供更好的职业结构,(9)加强机构对产品实现的支持,以及(10)更好地认可癌症研究人员。
