OBJECTIVETo investigate the trend of total cancer mortality in Linqu County Shandong Province from 1980 to 2002.

METHODSA retrospective survey on all causes of death in 1980 - 1982, 1990 - 1992 and 2000 - 2002 was conducted in Linqu County, a high risk area of gastric cancer in Northeast of China, respectively.

RESULTSThe cancer death, was found the third leading cause of death in 1980 - 1982 in Linqu County, and the second to that of vascular disease in 2000 - 2002. The cancer mortality (standardized mortality) was 108.97/100,000 (111.48/100,000), 132.38/100,000 (127.94/100,000) and 148.48/100,000 (105.53/100,000) in 1980 - 1982, 1990 - 1992 and 2000 - 2002, respectively. The trend of cancer mortality was significantly increased (Z = 13.42, P < 0.0001). The added cancer-eliminated life expectancy in three periods was 2.46 years, 3.29 years and 3.76 years in male (F = 13.99, P < 0.0001), and 1.67 years, 2.30 and 2.33 years in female (F = 13.61, P < 0.0001), respectively. The standardized mortality of gastric cancer (percentage in all cancer death) was 44.93/100,000 (40.29%), 41.37/100,000 (32.34%) and 27.73/100,000 (26.90%) in 1980 - 1982, 1990 - 1992 and 2000 - 2002, respectively. The trend of gastric cancer standardized mortality was significantly reduced (Z = 6.35, P < 0.01).

CONCLUSIONThe mortality of cancer in Linqu County has been increased from 1980 to 2002, but no such trend was found after adjusting ages. However, there was a decreased trend on standardized mortality of gastric cancer in the past 20 years.

OBJECTIVETo describe the current status of mortality breast cancer in Chinese females between 2004 and 2005, as well as its developing trend from 1973 to 2005.

METHODSThe data of female breast cancer deaths and number of female under exposure were collected through the Third National Mortality Retrospective Sampling Survey, which covered a total of 69 690 241 person years of females. The data was descriptively analyzed, and compared with the data of time-trend of breast cancer mortality in the previous two surveys in 1973 - 1975 and 1990 - 1992 respectively.

RESULTSThe crude mortality of female breast cancer in China in 2004 - 2005 was 5.90 per 100 000 (4112/69 690 241), ranking the sixth most common cancer death in Chinese females, and accounted for 5.90% (4112/69 667) of all female deaths from cancer. The crude mortality of female breast cancer was 6.86/100 000 (1777/25 900 856) in the eastern China, 5.91/100 000 (1431/24 225 738) in the central China and 4.62/100 000 (904/19 563 647) in the western China. The age-standardized mortality among Chinese standard population of female breast cancer in urban area (4.91/100 000, 1899 death cases) was 1.44 times higher than that in rural area (3.42/100 000, 2213 death cases). The crude mortality increased 99.99% from 1973 - 1975 (2.95/100 000) to 2004 - 2005 (5.90/100 000), the absolute figure increased by 2.95/100 000. The age-standardized mortality among Chinese standard population increased 37.85% from 1973 - 2005 (2.88/100 000) to 2004 - 2005 (3.97/100 000), the absolute figure increased 1.09/100 000.

CONCLUSIONThe mortality of female breast cancer in urban area was higher than that in rural area, and it decreased from the eastern China, to the central China and to the western China in turn. The mortality of female breast cancer has constantly increased in China since 1973.

To estimate the cancer incidences and mortalities in China in 2010, the National Central Cancer Registry (NCCR) of China evaluated data for the year of 2010 from 145 qualified cancer registries covering 158,403,248 people (92,433,739 in urban areas and 65,969,509 in rural areas). The estimates of new cancer cases and cancer deaths were 3,093,039 and 1,956,622 in 2010, respectively. The percentage of morphologically verified cases were 67.11%; 2.99% of incident cases were identified through death certification only, with the mortality to incidence ratio of 0.61. The crude incidence was 235.23/100,000 (268.65/100,000 in males and 200.21/100,000 in females). The age-standardized rates by Chinese standard population (ASR China) and by world standard population (ASR world) were 184.58/100,000 and 181.49/100,000, respectively, with a cumulative incidence (0-74 years old) of 21.11%. The crude cancer mortality was 148.81/100,000 (186.37/100,000 in males and 109.42/100,000 in females). The ASR China and ASR world were 113.92/100,000 and 112.86/100,000, respectively, with a cumulative mortality of 12.78%. Lung, breast, gastric, liver, esophageal, colorectal, and cervical cancers were the most common cancers. Lung, liver, gastric, esophageal, colorectal, breast, and pancreatic cancers were the leading causes of cancer deaths. The coverage of cancer registration has rapidly increased in China in recent years and may reflect more accurate cancer burdens among populations living in different areas. Given the increasing cancer burden in the past decades, China should strengthen its cancer prevention and control.

OBJECTIVETo evaluate the trend of cervical cancer incidence and mortality rates during 1989-2008 in Chinese women, so as to inform the development of relevant policies and strategies in China.

METHODSThe incidence and mortality rates of cervical cancer during 1989-2008 in urban and rural areas were calculated based on the data from the National Cancer Registry Database. Age-standardized rates were calculated using the Chinese population of 1982 and World Segi's population of 1985. Joinpoint regression analysis was performed to obtain annual percentage changes (APC) so as to assess the trend of incidence and mortality rates over the period from 1989 to 2008.

RESULTSThe crude incidence rate of cervical cancer in Chinese women increased from 3.06/10(5) in 1989-1990 to 11.87/10(5) in 2007-2008 (from 4.96/10(5) to 11.98/10(5) in urban registration areas and from 2.39/10(5) to 11.77/10(5) in rural registration areas).The crude mortality rate slightly increased from 2.19/10(5) in 1989-1990 to 3.20/10(5) in 2007-2008 (from 3.21/10(5) to 2.56/10(5) in urban registration areas and from 1.82/10(5) to 3.75/10(5) in rural registration areas). Generally, the upward trends of crude incidence rates were shown over the year 1989-2008, with an APC of 14.4% after 1997 in urban areas and 22.5% after 1999 in rural areas.After age standardization of world population, the APC of incidence rates in recent decade in urban areas remained stable, and the one in rural areas slightly decreased.Although the overall crude and world age-standardized mortality rates had no significant changes during 1989-2008, the crude mortality rates increased by 8.1% annually after 1999.The upward trends were also shown for crude and world age-standardized mortality rates in urban areas after 2001 with an APC of 7.3%.The crude mortality rates in rural areas increased by 3.9% annually during 1989-2008, but no significant change was found after age standardization.

CONCLUSIONSOver the last decade, the cervical cancer incidence and mortality rates ascended by year in China. It is particularly urgent to establish a comprehensive prevention and control system that combines cervical cancer screening and human papillomavirus vaccination, so as to reduce the burden of cervical cancer in Chinese women.

In 2012, the National Central Cancer Registry (NCCR) of China collected cancer registration information for the year 2009 from local cancer registries and analyzed it to describe the incidences and mortalities of cancers in China. Based on the data quality criteria from NCCR, data from 104 registries covering 85,470,522 people (57,489,009 in urban areas and 27,981,513 in rural areas) were checked and evaluated. The data from 72 registries were qualified and accepted for the cancer registry annual report in 2012. The total cancer incident cases and cancer deaths were 244,366 and 154,310, respectively. The morphologically verified cases accounted for 67.23%, and 3.14% of the incident cases only had information from death certifications. The crude incidence in the Chinese cancer registration areas was 285.91/100,000 (317.97/100,000 in males and 253.09/100,000 in females). The age-standardized rates for incidences based on the Chinese standard population (ASRIC) and the world standard population (ASRIW) were 146.87/100,000 and 191.72/100,000, respectively, with a cumulative incidence of 22.08%. The cancer mortality in the Chinese cancer registration areas was 180.54/100,000 (224.20/100,000 in males and 135.85/100,000 in females). The age-standardized rates for mortalities based on the Chinese standard population(ASRMC) and the world standard population (ASRMW) were 85.06/100,000 and 115.65/100,000, respectively, and the cumulative mortality was 12.94%. Lung cancer, gastric cancer, colorectal cancer, liver cancer, esophageal cancer, pancreatic cancer, encephaloma, lymphoma, female breast cancer, and cervical cancer were the most common cancers, accounting for 75% of all cancer cases. Lung cancer, gastric cancer, liver cancer, esophageal cancer, colorectal cancer, pancreatic cancer, breast cancer, encephaloma, leukemia, and lymphoma accounted for 80% of all cancer deaths. The cancer registration's population coverage has been increasing, and its data quality is improving. As the basis of the cancer control program, the cancer registry plays an important role in directing anticancer strategies in the medium and long term. Because cancer burdens are different in urban and rural areas in China, prevention and control efforts should be based on practical situations.

BACKGROUND/AIMS: This study introduces methods for estimating the cost of liver disease and presents useful and reliable sources of data. The available evidence on the costs associated with liver disease is also discussed. METHODS: Costing methodology can be used to identify, measure, and value relevant resources incurred during the care of patients with liver diseases. It adjusts for discounting, skewed distribution, and missing or censored cost data. The human capital approach for productivity cost assumes that deceased patients would have lived to a normal expected life expectancy, and have earned a salary in line with the current age profile of wages, in order to measure potential earnings lost due to premature death or job loss. EVIDENCE: The number of deaths due to liver cancer (C22) increased from 6,384 in 1983 to 11,405 in 2013, while deaths due to other liver diseases (K70-K76) increased from 12,563 in 1983 to 13,458 in 1995, and then declined to 6,665 in 2013. According to the Global Burden of Disease study conducted by the World Health Organization, liver cancer caused 325,815 disability-adjusted life years (DALYs), and cirrhosis of the liver caused 206,917 DALYs in 2012. The total cost of liver disease was estimated at 1,941 billion Korean won in 2001 and 5,689 billion Korean won in 2008. Much of this cost is attributable to productivity cost, and especially that of economically active men. CONCLUSIONS: The economic burden of liver disease is immense because of the associated high mortality and morbidity, especially among the economically active population. This indicates the need to prioritize the development of appropriate health interventions.
