据估计,2011年加拿大新发恶性肿瘤病例约17.8万例,7.5万人死于恶性肿瘤,居加拿大死因首位。加拿大男性恶性肿瘤发病率近二十年来有所下降,肺癌发病率下降趋势较为明显,烟草控制效果开始显现;女性恶性肿瘤发病率则呈缓慢上升趋势,主要与女性肺癌、甲状腺癌和非霍奇金淋巴瘤的发病率上升有关。加拿大男性恶性肿瘤死亡率呈现逐步下降趋势,早期筛查和治疗水平的提高是主要原因,女性恶性肿瘤死亡率基本保持稳定。加拿大癌症控制计划(Canadian Strategy for Cancer Control,CSCC)为肿瘤防控机构和组织建立了纽带,通过各地区和组织的协调行动,使得肿瘤防控更加高效,促进了加拿大的肿瘤防控工作。
It is estimated that in 2011, about 178,000 cases of new malignancies in Canada and 75,000 people died of malignant tumors, ranking the first cause of death in Canada. In Canada, the incidence of malignant tumors in men has been declining in the recent two decades, the incidence of lung cancer has been declining more obviously and the effect of tobacco control has begun to appear. The incidence of malignant tumors in women has been increasing slowly, mainly associated with female lung cancer, thyroid cancer and non-Hodgkin’s Gold lymphoma incidence increased. The mortality rate of male malignant tumor in Canada shows a gradual downward trend. The early screening and treatment are the main reasons for the increase. The mortality rate of female malignant tumors has basically remained stable. The Canadian Cancer Control Program (CSCC) has established a link between cancer prevention and control agencies and organizations. By coordinating the efforts of various regions and organizations, cancer prevention and control have become more effective and the cancer prevention and control work in Canada has been promoted.
