Abstract:
OBJECTIVE: To analyze the cancer incidence and mortality of Henan province in 2009. METHODS: On basis of the criteria of data quality from the National Central Cancer Registry (NCCR), data from 6 registries in Henan province were evaluated, covering 6 061 564 people, accounting for 6.45% of the total population in Henan in 2009. There were 3 104 991 people of males, and 2 956 573 people of females. The incidence, mortality, 10 most common cancers, constitution and cumulative rate (0-74 years old) were then calculated. The age-standardized rate was calculated and adjusted by the Chinese standard population in 1982 as well as the Segi's world standard population. RESULTS: There were 12 091 new diagnosed cancer and 8040 death cases registered in Henan province in 2009. The rate of pathological diagnosis was 68.2% (8246/12 901) and only 1.75% (2116/12 901) had death certificates. The ratio of mortality and incidence was 0.66 (8040/12 091). The incidence rate was 199.47/100 000 (12 091/6 061 564) in total, and it was 216.36/100 000(6718/3 104 991) in males and 181.73/100 000(5373/2 956 573) among females. The standardized incidence by Chinese population was 126.50/100 000 and it was 166.08/100 000 by world's population. The cumulative rate was 19.95% between 0 and 74 years old. The incidence was the highest in Linzhou city, whose standardized incidence was 156.87/100 000 by Chinese population and the incidence was the lowest in Shenqiu city, whose standardized incidence was 104.82/100 000 by Chinese population. The morphology verified cases accounted for 68.2% (8246/12 091), death certification cases only accounted for 1.75% (2116/12 091), and mortality to incidence ratio was 0.66 (8040/12 091). The crude incidence in cancer registration areas of Henan province was 199.47/10 000 (12 091/6 061 564), 216.36/10 000(6718/3 104 991) for males, 181.73/10 000 (5373/2 956 573) for females, age-standardized incidence rates by Chinese standard population and by world standard population were 126.50/10 000 and 166.08/10 000 with cumulative incidence rate (0-74 age years old) of 19.95%. The crude mortality in cancer registration areas of Henan province was 132.64/100 000 (8040/6 061 564), separately 160.58/100 000 (4986/3 104 991) for males and 103.30/10 000 (3054/2 956 573) for females. The age-standardized mortality rates by Chinese standard population and by world's standard population were 78.41/10 000 and 107.49/10 000. The cumulative mortality rate (0-74 age years old) was 12.18%. The mortality rate was the highest in Linzhou city, whose standardized rate was 93.35/100 000 by Chinese population, and the lowest mortality rate was in Yuzhou city, whose standardized rate was 67.95/100 000. The most common cancers were lung cancer, esophageal cancer, gastric cancer, liver cancer, breast cancer, rectum cancer, brain nervous system cancer, colon cancer, cervical cancer and uterus cancer, all of which accounted for 82.23% (9943/12 091) of the registered cancers.Lung cancer, esophageal cancer, gastric cancer, liver cancer, breast cancer, rectum cancer, brain nervous system cancer, pancreas cancer, colon cancer and gallbladder carcinoma were the major causes for the death, accounting for 86.30% (6938/8040) of all cancer deaths. CONCLUSION: Both incidence and mortality of cancer in Henan province were lower than the level in China, prevention and control should be implemented based on practical situation.
