Latest global cancer survival data report

Source: Ding Xiangyuan 2015-03-19 global data on cancer survival rate are rare In the concord-2 study, allemani C1, Ph.D of the partnership cancer center in Toronto, Canada, and other researchers analyzed the population-based registration data to obtain the global cancer survival monitoring data, which was used as a standard to measure the effectiveness of the health system, and provided reference for the development of global cancer control policies The paper was published in the recent online edition of lancet magazine The concord-2 study tracked and analyzed cancer survival data worldwide In this large survey, researchers collected data from 279 cancer registries in 67 countries, including 2570000 adult cancer patients (15-99 years old) and 75, The data of 000 children (0-14 years old) were analyzed in the center The survey covers a variety of cancers including colon cancer, rectal cancer, lung cancer, gastric cancer, liver cancer, breast cancer, prostate cancer, ovarian cancer, leukemia, etc Figure 1 279 population-based cancer patients from 67 countries were enrolled in the study All the subjects were diagnosed in 1995-2009 After the follow-up to December 31, 2009, 25.7 million adult cases (aged 15-99) and 75000 children cases (aged 75-99) were included 0-14 years old) The types of cancer monitored are as follows: adult gastric cancer, colon cancer, rectal cancer, liver cancer, lung cancer, breast cancer (female), cervical cancer, ovarian cancer and prostate cancer, and adult and child leukemia Using the standardized quality control process, the researchers used the relevant registry to correct the errors The 5-year survival rate was assessed after adjusting for background mortality by age (single year), gender for each country or region, and in some countries by race or ethnic origin The international cancer survival standard weight was used for age standardized evaluation Figure 2 The results of Asian countries and regions involved in the survey show that the 5-year survival rate of colorectal cancer, rectal cancer and breast cancer patients in most developed countries is steadily increasing From 2005 to 2009, the survival rate of colorectal cancer and rectal cancer patients diagnosed in 22 countries reached more than 60%; 17 countries' breast cancer patients' 5-year survival rate reached more than 85% Liver cancer and lung cancer are still fatal diseases in all countries The 5-year survival rates of these two cancers are lower than 20% in Europe, 15% - 19% in North America, and 7% - 9% in Mongolia and Thailand Among women diagnosed with breast cancer in 2005-09, the 5-year survival rate of 34 countries reached 80%, and that of 17 countries increased to 85% or higher Countries with breast cancer survival rates below 70% are Malaysia (68%), India (60%), Mongolia (57%) and South Africa (53%) Figure 3 The 5-year survival rate of liver cancer and lung cancer in some breast cancer data is generally low In all countries, liver cancer and lung cancer are fatal diseases, and in most countries, it is only 10% - 20% between 1995 and 2009 From 2005 to 2009, only some East Asian countries and regions such as Japan, South Korea and Taiwan had the survival rate of more than 20% The 5-year survival rate of liver cancer increased in North America, 4 Asian countries and 13 European countries The 5-year survival rate of lung cancer in China increased from 8% to 18%, in India from 4% to 10%, and in South Korea from 10% to 19% Prostate cancer survival rates vary greatly in countries around the world The 5-year survival rates of prostate cancer in many countries have increased significantly The data are as follows: the 5-year survival rates of 22 countries in South America, Asia and Europe increased significantly by 10% - 20% in 1995-1999 and 2005-2009 Bulgaria and Thailand have less than 60% five-year survival, while Brazil, Puerto Rico and the United States have more than 95% The regional difference of 5-year survival rate of cervical cancer is also very large, the small is lower than 50% and the high is 70%, and the improvement of survival rate in 1995-1999 and 2005-2009 is limited Figure 4 Lung cancer data benefit from the introduction of prostate specific antigen (PSA) detection technology The 5-year survival rate of prostate cancer has increased significantly in many countries In 22 countries in South America, Asia and Europe, the survival rate increased by 10% - 20% from 1995-1999 to 2005-2009 But the survival of different areas is very different The regional difference of 5-year survival rate of ovarian cancer and ovarian cancer is very large Generally speaking, the improvement rate is poor The countries and regions with 5% - 10% increase rate are Bulgaria, Denmark, France, Hong Kong, Iceland, Latvia and Portugal Only Ecuador, the United States and 17 sub European countries have a 5-year survival rate of more than 40% in ovarian cancer patients diagnosed in 2005-2009 The survival rate of gastric cancer in Japan and South Korea (54% - 58%) is higher than that in other countries (< 40%), however, the 5-year survival rate of adult leukemia in these two countries is lower than that in most countries (18% - 23%) In some countries, the 5-year survival rate of children with acute lymphoblastic leukemia is less than 60%, while in Canada and Europe, the 5-year survival rate is as high as 90%, which indicates that there are still many deficiencies in the management of curable diseases The survival rate of leukemia in East Asia seems to be low (from 19% in Japan to 23% in South Korea and Taiwan), slightly higher in West Asia (from 33% in Turkey to 53% in Qatar), and mixed with other Asian countries (from 7% in Jordan to 40% in Indonesia) The survival rates of China, Denmark, Germany, Iceland, Latvia, Sweden and New Zealand increased by 10% - 16% The survival rate in North America, Israel, Japan, South Korea and 10 European countries increased by 5% - 9% According to the survey, 5-year survival rate of childhood acute lymphoblastic leukemia is lower than 60% in some countries, but as high as 90% in Canada and European countries The 5-year survival rate of gastric cancer in Japan and South Korea was higher than that in other countries (54% - 58%), while the 5-year survival rate of adult leukemia in these two countries was lower than that in most other countries (18% - 23%) The 5-year survival rate of gastric cancer is 30% - 39% in Austria, Belgium, China, Germany, Iceland, Italy, Portugal, Switzerland and Taiwan From 1995-99 to 2005-09, the 5-year survival rate of colorectal cancer in most countries has been significantly improved The 5-year survival rate of colorectal cancer patients has reached 50% - 59% in many countries South Korea, North America, Oceania and nine European countries reached 60% - 69% The researchers believe that the global survival trend survey indicates that there is a large regional gap, and the difference in resources for early diagnosis and optimal treatment may be the reason Continuous monitoring of cancer survival worldwide can provide cancer patients and researchers with indispensable information, as well as a source of information for governments to improve health policies and health care systems
