Objective: To investigate the characteristics and trends of cancer incidence from 2002 to 2011 in the Tianjin area of China.
Methods: Based on the Tianjin Public Health Bureau statistics data from 2002 to 2011, the incidences of cancer were analyzed according to sex, age group, cancer site, and geographic region (Tianjin area versus overall China from 2003 to 2007).
Results: The crude incidence of cancer in Tianjin was 162.33 per 100,000 (men: 163.22 per 100,000; women: 161.43 per 100,000). Age-standardized incidences according to the Chinese standard population (Age-standardized rate (ASR) China) and the world standard population were 84.05 and 107.67 per 100,000, respectively. From 2002 to 2011, the incidence of cancer increased from year to year. Age-specific incidence reached a peak at 703.60 per 100,000 in the age group of 75–79 years old. Among group between 25 and 54 years old, the cancer incidence rate of the male group was significantly lower than that of the female group ( P<0.05) ; Among people aged over 60, the cancer incidence rate of the male group was significantly higher than that of the female group ( P<0.05) . The most common cancer in Tianjin residents was lung cancer, followed by breast cancer, colorectal cancer, stomach cancer, and liver cancer. The five most common sites for cancer in men were lung, liver, stomach, colorectal, and bladder, while in women were breast, lung, colorectal, stomach, and cervix.
Conclusions: From 2002 to 2011, the incidence of cancer has been increasing. In view of the high incidence of lung and breast cancers in Tianjin, early screening focused on high-risk groups should be implemented to improve early diagnosis and treatment for these cancers.
