“…32 Despite the favorable pattern in developed areas reported over the last 3 decades, childhood cancers continue to represent an important cause of death worldwide. In Australia, for 2004 to 2006, cancer was the second leading cause of death among children ages 1 to 14 years 28 and the fourth leading cause in Japan among children aged 0 to 14 years, 26 confirming the key role of childhood cancer care and the importance of advancements in its management worldwide. Improvements in the adoption of current integrated treatment protocols in Latin American and other lower-and middle-income countries worldwide would prevent a substantial proportion of childhood cancer deaths.…”

“…Therefore, despite potential problems in death certification quality and validity, 7,24,25 like in Latin America, there is ample scope for further improvement in the management of children with cancer in those areas. Recent trends and rates in childhood cancer mortality in North America (and Puerto Rico), Japan, and Oceania were similar and were even more favorable than in the EU, 1,26 including several of the largest countries in western Europe (Italy, Spain, and the United Kingdom). Substantial declines in childhood cancer mortality in the United States were observed despite some suggestions of a moderate increase in incidence (0.6% per year during 1975 to 2002), which may have been caused at least in part by improved diagnostic accuracy.…”

BACKGROUND:Over the last 4 decades, childhood cancer mortality declined in most developed areas of the world. However, scant information is available from middle‐income and developing countries. The authors analyzed and compared patterns in childhood cancer mortality in 24 developed and middle‐income countries in America, Asia, and Oceania between 1970 and 2007.METHODS:Childhood age‐standardized annual mortality rates were derived from the World Health Organization (WHO) database for all neoplasms, bone and kidney cancer, non‐Hodgkin lymphoma (NHL), and leukemias.RESULTS:Since 1970, rates for all childhood cancers dropped from approximately 8 per 100,000 boys to 3 per 100,000 boys and from 6 per 100,000 girls to 2 per 100,000 girls in North America and Japan. Latin American countries registered rates of approximately 5 per 100,000 boys and 4 per 100,000 girls for 2005 through 2007, similar to the rates registered in more developed areas in the early 1980s. Similar patterns were observed for leukemias, for which the mortality rates were 0.81 per 100,000 boys and 0.55 per 100,000 girls in North America, 0.86 per 100,000 boys and 0.68 per 100,000 girls in Japan, and 1.98 per 100,000 boys and 1.65 per 100,000 girls in Latin America for 2005 through 2007. Bone cancer rates for 2005 through 2007 were approximately 2‐fold higher in Argentina than in the United States. During the same period, Mexico registered the highest rate for kidney cancer and Colombia registered the highest rate for NHL, whereas the lowest rates were registered by Japan for kidney and by Japan and the United States for NHL.CONCLUSIONS:Improvements in the adoption of current integrated treatment protocols in Latin American and other lower‐ and middle‐income countries worldwide would avoid a substantial proportion of childhood cancer deaths.

“…Also, mortality rate from tumors of the central nervous system in Argentinean children and adolescents was higher than that observed in developed countries such as Japan, Canada, United States of America, Italy and the United Kingdom, and lower than the rate reported in New Zealand for the 2000 decade. 15 As in other studies, boys had a higher mortality rate from leukemia and tumors of the central nervous system than girls. 11,[14][15][16][17] It is worth noting that, although in this study the incidence of childhood tumors by sex was not analyzed because no broken-down data were available, the ROHA publishes the male/female case ratio, indicating that most tumors, except for certain of the genitourinary tissues (germ cells), girls have a lower proportion of cases.…”

“…16 Likewise, mortality rate from leukemias in children and adolescents younger than 15 years old was higher than that in other developed countries. 3,15 However, the proportion of deaths from leukemia was lower than that reported in a Colombian study, where mortality from leukemia accounted for 48.6% of total deaths from malignancies, and its corresponding mortality rate (2005-2008) was 22.1 per million.…”

“…12 Such differences are based on the different stages of the epidemiological transition 13 taking place in Latin America, with an expected higher proportion of deaths caused by tumors (and other noncommunicable diseases) occuring in the more advanced stages, accompanied with a reduction in mortality rate from these causes due to a decrease in overall mortality in this age group, as observed in developed countries. 14,15 In relation to mortality by malignancy type, the most frequent was leukemia. The values in this study are higher than those reported in the USA, where mortality from leukemia in 2004 accounted for 25.5% of total cancer deaths in children and adolescents younger than 15 years old.…”

Introduction.Childhood cancer is a serious public health problem in any country given the large number of years of life lost in an early manner. Objective. To describe morbidity and mortality rates for cancer in Argentinean children and adolescents younger than 15 years old in the 2006-2008 three year period. Method. Specific mortality rates and incidence rates per million inhabitants were analyzed in children and adolescents younger than 15 years old by type of tumor and gender. Vital statistics data were used based on the databases provided by the Statistics and Health Information Department of the Ministry of Health of Argentina and the population of 0-14 year old children estimated by the National Statistics and Censuses Institute of Argentina (Instituto Nacional de Estadísticas y Censos, INDEC). In relation to morbidity data, the information published by the Argentine Hospital Oncopediatric Registry (Registro Oncopediátrico Hospitalario Argentino, ROHA) was used. Results. Mortality rate from malignancies was 43.8 per million (3.5% of total deaths in this age group) and the incidence rate was 123.7 per million. Leukemia had the highest specific mortality rate (14.9 per million), followed by tumors in the central nervous system (12.7 per million). The highest incidence rates were also registered for these tumors (45.2 and 15.5 per million, respectively). Conclusions. Mortality from malignancies accounted for 3.5% of deaths in children and adolescents younger than 15 years old in Argentina. Leukemia and tumors in the central nervous system had the highest specific mortality and incidence rates.

To better understand premature mortality due to cancer, we estimated years of life lost (YLL) and average years of life lost (AYLL) due to cancer for the years 1995 and 2005, based on data from the Vital Statistic of Japan. In men, we identified a total of 159,623 cancer deaths in 1995 and 196,603 Results showed that cancer of the stomach, colorectum, liver and lung were the most frequent cancers in both sexes in both 1995 and 2005 and responsible for a remarkable number of YLL. Further, AYLL was greatest for brain cancer and leukemia in both sexes and for sex-related cancers in women, namely breast, cervix and ovarian cancer.Cancer accounts for a major part of the total burden of disease worldwide. The number of people newly diagnosed with cancer each year totals in the millions, large numbers of whom died from it. 1 In Japan, cancer overtook stroke to become the leading cause of death in the early 1980s. As cancer incidence increases with age, the absolute cancer burden in Japan is expected to worsen in line with the aging of the Japanese population.Conventional methods of quantifying the burden of cancer have relied largely on the analysis of incidence and mortality rates. A more recent methodology, however, focuses on the measurement of premature death, which is a death occurring before the averaged life expectancy. The 2 measures of premature death are ''years of life lost'' (YLL) and ''average years of life lost'' (AYLL) 2,3 : the former is the number of years a death occurred earlier than it would have occurred in the absence of cancer, whereas the latter is the average of the differences between the actual ages at death of those who died of cancer and the expected age at death of those persons. Although high mortality may also be linked to an increase in premature death, mortality rates alone do not directly reflect the issues of premature death.We recently estimated YLL as well as AYLL due to cancer, but only among participants of a cohort study in Japan. 4 Here, to better understand premature mortality due to cancer in Japan as a whole, we estimated YLL and AYLL due to cancer for the years 1995 and 2005 by examining nationwide data on cancer deaths in Japan according to the respective life tables. Material and Methods Study populationWe obtained the mortality data for 5-year age groups from the Vital Statistic of Japan for the years 1995 and 2005, a 10-year interval period. 5,6 Causes of death were coded according to the International Classification of Diseases and Injuries (ICD), 10th Revision (ICD-10). This mortality data provide yearly number of deaths for all causes in the whole of Japan. The present analyses were restricted to cancer deaths (codes ranged from C00 to C97 in the ICD-10 Revision). Life tables for JapanIn Japan, the Ministry of Health, Labour and Welfare reports complete life tables every 5 years. The tables show functional data by age for death rate, survival rate and remaining life expectancy. In the present analyses, we used the complete life tables for 1995 and 2005 7,8
