Gastric cancer, or stomach cancer, occurs when abnormal cells grow in the stomach. It can develop anywhere in this organ. Knowing the statistics is vital because it shows how this malignancy impacts health globally. It ranks as the fifth most common cancer worldwide and the fourth leading cause of cancer related deaths. Despite declining rates in some regions, the global burden is projected to rise significantly by 2030, particularly in Eastern Asia, where it's the most prevalent. Understanding these numbers guides efforts in prevention, treatment, and policy, aiming to improve outcomes and lessen its impact on public health.
Incidence and Mortality Rates
In 2020, gastric cancer accounted for over 1,089,000 new cases globally, leading to 769,000 deaths. While overall trends show a decrease in incidence and mortality over the past decade, some regions and age groups are experiencing rising rates. Looking forward, although mortality rates are expected to decline by 2035, the absolute number of deaths may rise due to population growth.
Regionally, Eastern Asia, including China, Japan, and South Korea, reported the highest incidence rates in 2020 at 22.4 cases per 100,000 people. Central and Eastern Europe followed with 11.3 per 100,000, and South America with 8.7 per 100,000. In contrast, North America had lower rates at 4.2 per 100,000, and Africa ranged from 3 to 4 per 100,000. Interestingly, high-income countries in the Asia Pacific also recorded significant incidence rates.
Country-specific trends highlight variations: Canada, Brazil, Denmark, India, and Israel have shown less decline in gastric cancer cases. Predictions suggest rising mortality rates in Slovenia and among French women by 2035, indicating localized challenges despite global trends. Understanding these
statistics aids in targeted interventions to reduce the burden of gastric cancer worldwide, emphasizing prevention, early detection, and improved treatment outcomes.
Survival Rates Across Stages
Survival rates for stomach cancer vary significantly by stage: Stage 1 shows a promising 65% survival rate over 5 years after diagnosis, dropping to about 35% for Stage 2 and 25% for Stage 3. Unfortunately, Stage 4 lacks specific 5-year survival data, with approximately 20% surviving beyond the first year after diagnosis.
Early detection plays a crucial role in improving these outcomes. Regular screenings and awareness of symptoms can lead to timely intervention, potentially allowing for curative surgery and better treatment outcomes. Advances in surgical techniques, chemotherapy, and targeted therapies have also contributed positively to survival rates. Personalized treatment plans, including immunotherapies and precision medicine, are tailored to individual needs, enhancing prognosis.
A multidisciplinary approach involving oncologists, surgeons, and other specialists further supports patient care and outcomes. It's essential for individuals to stay informed, prioritize early detection through screenings, and consult healthcare professionals promptly for personalized guidance and the best possible prognosis.
