Abstract
Objective: The study aimed to assess the characteristics of pancreatic cancer deaths and the relationship between socio-demographic status and mortality risk of pancreatic cancer in Inner Mongolia. Method: We obtained our data for 2008-2014 from the Death Registry System of Inner Mongolia. We calculated the mortality rate, potential years of life lost (PYLL) and average years of life lost (AYLL) for men and women. We collected socio-demographic characteristics including education level, ethnicity, region, and occupation. Logistic regression models were employed to analyze risk factors of pancreatic cancer. Results: The average mortality rate of pancreatic cancer was 4.42/100,000 in Inner Mongolia during 2008 to 2014. Mortality rate in men was higher in all age groups compared with those in women. The highest mortality rate was 1.3 times than the lowest mortality rate for men and 1.6 times for women during seven years. Average AYLL in women were more than 3.4 years compared with that in men. PYLLR in women was fluctuated from 0.41 to 0.63 per thousand during 2008 to 2014. In eastern region, no occupation and high education level had a higher risk of pancreatic cancer. Conclusion: In Inner Mongolia, the mortality rate associated with pancreatic cancer was higher in men compared with in women. More than 65 years old groups had high death risk for pancreatic cancer. Average years of life lost for women were significantly higher than that for men. We should pay more attention to the older men.
Highlights
Pancreatic cancer has been considered an “orphan cancer” and would be of little concern except for its exceptionally high mortality rate [1]
We didn’t find the epidemiological study of pancreatic cancer death in Inner Mongolia till the paper analyzes the potential years of life lost, average years of life lost and influencing factors of pancreatic cancer mortality in Inner Mongolia in 2008-2014
Our study showed that women had a higher average years of life lost (AYLL) than that in men, though men had higher pancreatic cancer mortality rate
Summary
Pancreatic cancer has been considered an “orphan cancer” and would be of little concern except for its exceptionally high mortality rate [1]. Pancreatic cancer is placed in the eighth for mortality rate among any type of cancer [2]. At the beginning of the 21st century, the estimated number of pancreatic cancers death throughout the world was 110,000, with an estimated mortality rate of 98% [5]. We have found that the mortality rate of pancreatic cancer had an increasing trend. In Japan, the mortality rate had been increasing in 1968-2002 [6]. The death cases of pancreatic cancer in China were beyond the number of cases in the United States in 2010 [5]. We didn’t find the epidemiological study of pancreatic cancer death in Inner Mongolia till the paper analyzes the potential years of life lost, average years of life lost and influencing factors of pancreatic cancer mortality in Inner Mongolia in 2008-2014
