Q2. What future works have the authors mentioned in the paper "Global surveillance of cancer survival 1995–2009: analysis of individual data for 25 676 887 patients from 279 population-based registries in 67 countries (concord-2)" ?
Projections of the future burden of cancer106 are based on the same cancer incidence data. However, if cancer registration is to develop further in support of the 25 × 25 goals and in the evaluation of clinical care,111 WHO and the UN will need to address the growing legal and procedural diffi culties in obtaining primary health data and in accessing them for research.
Q3. How many countries have a 5-year survival rate for colon and rectal cancer?
For patients diagnosed during 2005–09, survival for colon and rectal cancer reached 60% or more in 22 countries around the world; for breast cancer, 5-year survival rose to 85% or higher in 17 countries worldwide.
Q4. How is the survival from childhood acute lymphoblastic leukaemia?
5-year survival from childhood acute lymphoblastic leukaemia is less than 60% in several countries, but as high as 90% in Canada and four European countries, which suggests major defi ciencies in the management of a largely curable disease.
Q5. What is the average survival for a cancer?
Liver and lung cancer remain lethal in all nations: for both cancers, 5-year survival is below 20% everywhere in Europe, in the range 15–19% in North America, and as low as 7–9% in Mongolia and Thailand.
Q6. What is the purpose of this study?
The authors aimed to initiate worldwide surveillance of cancer survival by central analysis of population-based registry data, as a metric of the eff ectiveness of health systems, and to inform global policy on cancer control.
Q7. How many people have survived prostate cancer?
Striking rises in 5-year survival from prostate cancer have occurred in many countries: survival rose by 10–20% between 1995–99 and 2005–09 in 22 countries in South America, Asia, and Europe, but survival still varies widely around the world, from less than 60% in Bulgaria and Thailand to 95% or more in Brazil, Puerto Rico, and the USA.
Q8. How long did the survival for stomach cancer in 2005-09 be?
5-year survival for stomach cancer in 2005–09 was high (54–58%) in Japan and South Korea, compared with less than 40% in other countries.
Q9. How many people were diagnosed with cancer during the period 1995–2009?
Methods Individual tumour records were submitted by 279 population-based cancer registries in 67 countries for 25·7 million adults (age 15–99 years) and 75 000 children (age 0–14 years) diagnosed with cancer during 1995–2009 and followed up to Dec 31, 2009, or later.
Q10. How many countries have a 5-year survival rate?
For women diagnosed with ovarian cancer in 2005–09, 5-year survival was 40% or higher only in Ecuador, the USA, and 17 countries in Asia and Europe.
Q11. What is the purpose of this article?
Continuous worldwide surveillance of cancer survival should become an indispensable source of information for cancer patients and researchers and a stimulus for politicians to improve health policy and health-care systems.
Q12. What is the metric of survival for cancer?
The authors looked at cancers of the stomach, colon, rectum, liver, lung, breast (women), cervix, ovary, and prostate in adults, and adult and childhood leukaemia.
Q13. How many years of survival have been estimated for cancer?
The authors estimated 5-year net survival, adjusted for background mortality in every country or region by age (single year), sex, and calendar year, and by race or ethnic origin in some countries.
