[Cancer incidence in Iran in 2002 an international estimation]

During the past century, because of an improvement in the socio-economic conditions in the society and as a consequence a change in the predisposing or risk factors, incidence of diseases has undergone a real change. A decrease in the incidence of infectious diseases and an increase in the incidence of non-infectious diseases and accidents are the major reasons for this changer which has specially affected the developing countries. Presently, cancer is the second most common cause of morbidity and mortality. Control and reduction of the expenses of these types of diseases need planning and execution of a national cancer, but planning such a programme requires valid and authentic information. Such information is only possible through the registration of cancer cases. This paper provides information obtained from five provinces in the country about cancer to evaluate the incidence of it in the country, and comparison of with Globocan as an international reference about the incidence of cancer. By using statistical methods and establishing simple means about the incidence of cancer in Ardabil, Golestan, Mazandaran, Kalanshehr and Tehran according to age and gender, the incidence of cancer in the country was established. At least 50820 new cancers occur in the country yearly out of which 53% are found in males. The five major cancers to ASA in males were stomach [26.1], esophagus [17.6], colorectal [8.2], bladder [8], leukaemia [4.8], and in females were breast [17.1], esophagus [11.4], stomach [11.1], colorectal [6.7] and uterus 4.5 per 10[5]

Time trends, estimates and projects for breast cancer incidence and mortality in China / 中华肿瘤杂志

<p><b>OBJECTIVE</b>Using comprehensive available data on women breast cancer in China, to describe the mortality trends from late 1970s, estimate and project the profile in 2000 and 2005, and to aim to provide a reference for clinic, basic research and prevention and control strategy making for breast cancer in China.</p><p><b>METHODS</b>Using Joinpoint model, the mortality trends were analyzed on the basis of routine surveillance data. Combining with the data from the second national mortality survey and several cancer registries, using the log-linear model (based on Poisson distribution), the breast cancer profile in 2000 and 2005 were estimated and projected.</p><p><b>RESULTS</b>Although there was a slight decline in mortality between early 1970s and 1990s, the age-specific mortality rates among young and middle age women increased dramatically which followed a continuing increase trend on both rates and absolute numbers, in both urban and rural areas in recent 15 years. Compared with 2000, there are 470 thousands more new breast cancer cases and 130 thousands more deaths from breast cancer in 2005.</p><p><b>CONCLUSION</b>Due to the double effects of both increasing risk factors and population growth and ageing, breast cancer will be one of the most extensively increasing cancers in Chinese women. The prevention and control of breast cancer will be of great emphasis for future cancer control strategy in China.</p>
