Analysis of cancer incidence and mortality data in Heilongjiang province cancer registries, China, 2015

Objective In recent years, the rising incidence of cancer has increased patients’ living and economic burdens. This study analyzed the incidence and death due to malignant tumors in tumor registries in Heilongjiang province(China) in 2015 to provide a scientific basis for the prevention and treatment of malignant tumors in this province. Methods Data on tumor incidence and patient deaths were collected from seven tumor registries in Heilongjiang province(China) in 2015. According to the stratification of urban and rural areas and patient sex, the crude, standard, and accumulative rates(0–74 years of age) were calculated. The 2000 China Population Census data and Segi’s standard population were used to calculate the age-standardized rates. Results In 2015, the incidence rate of malignant tumors in Heilongjiang cancer registries was 259.90/100 000. The age-standardized incidence rates in the Chinese and world standard populations were 158.89/100 000 and 155.06/100 000, respectively, with a cumulative incidence rate(0–74 years) of 17.68%. The incidence of malignant tumors in urban areas was 273.55/100 000, while that in rural areas was 220.32/100 000. The incidence of malignant tumors in men was 270.89/100 000, higher than that in women(249.04/100 000). Lung cancer had the highest incidence, followed by breast cancer, liver cancer, colorectal cancer, and thyroid cancer. The mortality rate of malignant tumors in Heilongjiang cancer registries was 164.69/100 000. The age-standardized mortality rates in Chinese and in world standard populations were 95.29/100 000 and 94.35/100 000, respectively, with a cumulative mortality rate(0–74 years) of 10.44%. The mortality rate of malignant tumors in urban areas was 169.51/100 000, while that in rural areas was 150.72/100 000. The mortality rate of malignant tumors in men was 201.64/100 000, higher than that in women(128.21/100 000). Lung cancer had the highest mortality, followed by liver cancer, stomach cancer, colorectal cancer, and breast cancer.Conclusion Lung, liver, breast, and colorectal cancers were the most common cancers in Heilongjiang province, China, and should be considered the key cancer types for prevention and treatment. Moreover, the incidence of thyroid cancer is increasing, and thus early preventative measures should be implemented.
