[Cancer incidence and mortality in Pearl River Delta Area, 2009-2013]

Area of Science:

• Epidemiology
• Public Health
• Oncology

Background:

• Cancer poses a significant public health challenge globally and regionally.
• Understanding cancer burden is crucial for effective health policy and resource allocation.

Purpose of the Study:

• To estimate cancer incidence, mortality, and key characteristics in the Pearl River Delta (PRD) area of Guangdong Province from 2009 to 2013.
• To identify predominant cancer types and trends within this specific region.

Main Methods:

• Utilized population-based cancer registration data from five cities in the PRD (Guangzhou, Shenzhen, Zhongshan, Jiangmen, Sihui) for the 2009-2013 period.
• Calculated crude and age-standardized incidence and mortality rates using Chinese and Segi's standard populations.
• Analyzed cancer rates by gender and age groups to identify demographic patterns.

Main Results:

• The age-standardized cancer incidence rate was 225.63/100,000 (Chinese standard) and 219.88/100,000 (Segi's standard).
• The age-standardized cancer mortality rate was 116.02/100,000 (Chinese standard) and 114.31/100,000 (Segi's standard).
• Incidence and mortality increased with age, peaking in older populations (80+ for incidence, 85+ for mortality).
• Leading cancers by incidence included female breast, lung, colorectal, liver, and nasopharyngeal cancers.
• Top cancer causes of death were lung, liver, colorectal, female breast, and nasopharyngeal cancers.

Conclusions:

• The Pearl River Delta faces a substantial cancer burden.
• Lung, colorectal, nasopharyngeal, female breast, and male liver cancers are predominant and require focused intervention.
• Enhanced cancer control efforts are necessary to combat these prevalent malignancies in the region.
