Cancer epidemiology of an aging population in Upper-Northern Thailand from 2013 to 2017
Keywords:aging, cancer, epidemiology, incidence rate, mortality rate
Nowadays, Thailand is an aging society. The Thai population has changed its habits in terms of consumption, which has led to an increase in non-communicable diseases, especially cancer. Age is a factor related to occurring cancers. The objectives of the study were to study the incidence, mortality, and common cancers found in an aging population in upper-northern Thailand. This research used a retrospective study from population-based cancer data covering eight provinces in the upper-northern region, including Chiang Mai, Lampang, Lamphun, Phrae, Chiang Rai, Phayao, Nan, and Mae Hong Son. However, this research studied new cancer patients, with an age range of 60 years and over, and received a diagnosis of cancer during the 2013-2017, a total amount of 39,410 cases. In terms of the data analysis, the number of patients, percentage, and the incidence of cancer were classified by the type of cancer and by province, such as the age-standardized incidence rate (ASR) and the age-standardized mortality rate (ASMR) per 100,000 geriatrics. Moreover, the analysis was classified by sex and age range every five years, from 60 years and over, as follows: 61-64 years, 65-69 years, 70-74 years, 75-79 years, 80-84 years, and over 85 years. The results found that there was an aging population of 39,410 cancer patients in the upper-northern region of Thailand, which could be divided into 21,525 males and 17,885 females and an annual average of 7,882 cases. Furthermore, the age-standardized incidence rate of males and females were 91.9% and 67.8% per 100,000 of the population, respectively. Moreover, cancer mortality consisted of 24,056 cases and an annual average of 4,811 cases, with 13,803 males and 10,253 females. The age-standardized mortality rate of males and females were 58.9% and 38.4% per 100,000 of the population, respectively. The leading common cancers were the cause of death among the aging population. For males, it was lung cancer, liver and bile duct cancer, and colon and anus cancer, respectively. The leading common cancers among females included lung cancer, liver and bile duct cancer, and breast cancer, respectively. Therefore, public health agencies should have an integrated plan for the prevention and control of diseases in the aging group that is most at risk for common cancers occurring in the upper-northern region and at the primary, secondary, and tertiary levels.
