Keeping Fit May Boost Survival With Endometrial Cancer

Study found higher death risk for those who were overweight, physically inactive

TUESDAY, Jan. 8 (HealthDay News) -- Endometrial cancer patients are much more likely to die if they're overweight and physically inactive, a new study finds.

Researchers looked at how body-mass index (a measure of body fat based on height and weight) and physical activity levels were tied to survival in 1,400 women with endometrial cancer, which affects the lining of the uterus.

Patients with a BMI of between 25 to 29.9 (considered overweight) were 74 percent more likely to die within five years of diagnosis than patients with a healthy BMI of between 18.5 to 24.9. The risk of death was 84 percent higher for women with a BMI of 30 to 34.9 and 135 percent for those with a BMI of 35 or higher.

However, regardless of BMI, women who did more than seven hours a week of moderate to vigorous physical activity before they were diagnosed with endometrial cancer were 36 percent less likely to die within five years compared to women who never or rarely exercised.

Further research is needed to understand how weight and physical activity influence survival, but these factors may affect tumor progression through insulin resistance, circulating hormone levels and inflammation, the Yale School of Public Health researchers said.
