A team of Canadian scientists from the University of Montreal studied the impact of obesity on survival five years after diagnosis in children with cancer. The research was published in the scientific journal magazine American Cancer Society CANCER.
Researchers examined medical data from patients ages 2 to 18 with newly diagnosed cancer from across Canada. Of the 11,291 people with cancer, 10.5% were also obese.
The analysis showed that being overweight in a child at diagnosis increased the risk of disease recurrence by 16% and the risk of death by 29%.
The negative impact of obesity on prognosis was especially evident in patients with acute lymphoblastic leukemia and brain tumors.
According to the study authors, this discovery highlights the negative impact of obesity on all types of childhood cancer. The findings will help oncologists adjust and better predict treatment outcomes for younger patients.
