Objective:To describe and analyze the mortality trends of malignanttumors in Kunshan from 2000 to 2010,and to provide basic information for the prevention and treatment of malignant tumors in the area.Methods:The death data of malignant tumors which came from Kunshan Cancer Registry during 2000-2010 was coded according to ICD-10.Cancer mortality rate,standard mortality rate,age-specific mortality rate,death composition,sex ratio,potential years of life Iost(PYLL),standard potential years of life Iost(SPYLL),average years of life lost(AYLL)and other statistic indexes were calculated and analyzed.Results:1.Totally 13379 (male 8569,female 4810)death cases were reported in Kunshan from 2000 to 2010.2.Averagely,the crude mortality rate was 188.34 per 100 000(241.74 per 100 000 in males and 135.15 per 100 000 in females),the standard mortality rate was 118.36 per 100 000(149.70 per 100 000 in males and 86.16 per 100 000 in females).The mortality rates of males were higher than the females’.Crude rate and standard rate for cancer mortality both declined slightly during the eleven years. 3. The top ten mortality rate of malignant tumors were lung, stomach, liver, esophagus, colorectal and anal cancer, leukemia, breast cancer, nasopharyngeal cancer, bladder cancer and cervical cancer. 11 years, lung cancer death rate is rising; mortality decline of gastric cancer, esophageal cancer; liver, colorectal and anal cancer, cervical cancer increased and then decreased; leukemia, breast cancer, nasopharyngeal and bladder cancer ups and downs, the trend is not obvious.4.The mean age of malignant tumors mortality was 67.335 years old(67.343 years old in males and 67.321 years old in females)in Kunshan,2000-2010.Female’s mean age was older than male’s.With the age growingelder,cancer mortality rate increased.The age of death cases was mainlyover 45 years old which occupied 94.45 percent of deaths.The peak age specific rate of cancer mortality was observed in the age group 80-84,in which mortality rate was1394.04 per 100 000.5.There were different kinds of cancers in different age grouDs:Mortality rate in 0-14 years group was 4.54 per 100 000.Leukemia ranked first,29.27 percent among this group.Mortality rate in 15-44 years group was 20.67 per 100 000.Liver cancer was the leading cause of cancer death,representing 19.09% percent, followed by stomach cancer, lung cancer, leukemia, and colorectal and anal cancer.For 45—64 years group,mortality rate was 203.18 per 100 000.lung cancer was leading death cause,accounted for 20.14 percent, followed by stomach cancer, liver cancer, esophageal cancer, and colorectal and anal cancer .For over 65 years group,mortality rate was 1035.40 per 100000.lung cancer still ranked first,occupied 22.64 percent, followed by gastric cancer , liver cancer, esophageal cancer, and colorectal and anal cancer.6.The sex ratio was 1.78:1.For most cancer,mortality rate of males was higher than that of females,except for breast cancer.The Sex ratio ranged between 1.08 and 3.18:1.others such as bladder cancer, nasopharyngeal cancer, gastric cancer and esophageal cancer is also greater than the 2:1 sex ratio.7.During 2000 to 2010,the PYLL of malignant tumors in Feicheng was 80249 person-year,PYLL rate was 11.30 per 1 000.SPYLL was 62960.35 person-year,SPYLL rate was 8.86 per 1000.AYLL waS 6.00 years. Conclusions:During 2000 to 2010,the crude mortality rate of malignant tumors is 188.34 per 100 000,the standard mortality rate is 118.36 per 100 000 in Kunshan.These rates are significantly higher than those of the national average and Jiangsu Province’s average.The mortality rate and life reduction indexes of males are higher than those of females.Malignant tumors threaten to the health of males more seriously than that to the females.The mortality rate of digestive malignant tumor has been very high for 11 years.Therefore,the digestive malignant tumor should be the focus on malignant tumors monitoring and controlling.it also should be the main direction of cancer prevention and control in Kunshan.Theaged is by all means the risk group of cancer death,therefore the healthcare of the old should be reinforced.
