Endometrial Cancer Rates in the Philippines
Limited Philippines-Specific Data Available
The provided evidence does not contain specific incidence rates for endometrial cancer in the Philippines, but global data shows the Philippines is among countries experiencing the largest increases in endometrial cancer incidence over recent decades. 1
Global Context and Rising Trends
The Philippines is experiencing significant increases in endometrial cancer burden, particularly notable when compared to other countries:
Between 1978-2013, the Philippines showed one of the most pronounced increases in endometrial cancer risk both in consecutive generations and over time, alongside Japan, Belarus, Singapore, Costa Rica, and New Zealand 1
Globally, endometrial cancer is the sixth most common cancer in women, with 417,000 new cases and 97,000 deaths in 2020 2
Age-standardized incidence rates increased globally by 0.58% per year from 1990-2017, with the most dramatic increases occurring in countries undergoing rapid socioeconomic transitions 1, 3
Why Rates Are Increasing in the Philippines
Primary Drivers
The rising incidence in the Philippines reflects the country's rapid socioeconomic transition and adoption of Western lifestyle patterns, which directly impact the major risk factors for endometrial cancer 1:
1. Obesity Epidemic
- Obesity is the strongest modifiable risk factor, with obese women having a 2.54-fold increased risk (95% CI 2.11-3.06) compared to normal weight women 4
- Overweight status alone increases risk by 1.32-fold 4
- There is a strong positive association between high body mass index and endometrial cancer burden across all development levels 3
2. Metabolic Syndrome Components
- Hypertension increases risk 1.77-1.81 fold 4
- Type 2 diabetes approximately doubles the risk (OR 2.1; 95% CI 1.40-3.41), though obesity is a confounding factor 4
- Hypertriglyceridemia shows weaker but significant association (RR 1.17) 4
3. Aging Population
- Over 90% of endometrial cancer cases occur in women >50 years of age, with median diagnosis at 63 years 4
- The prevalence of comorbidities and metabolic syndrome increases with age 2
4. Reproductive Pattern Changes
- Nulliparity and infertility increase risk 4, 5
- Polycystic ovarian syndrome increases risk almost threefold (OR 2.79-2.89) 4
- Early menarche and late menopause each double the risk 4
5. Socioeconomic Development
- Countries experiencing rapid socioeconomic transitions show the steepest increases in endometrial cancer incidence 1
- This reflects adoption of sedentary lifestyles, Western dietary patterns, and decreased physical activity 3
Clinical Implications
Prevention Strategies Needed
The rising incidence in the Philippines demands urgent implementation of prevention strategies targeting obesity and metabolic syndrome 3, 6:
- Weight management through regular physical activity and healthy diet 4
- Control of hypertension and diabetes 4
- Combined oral contraceptive use significantly decreases risk with increasing duration 4
