The National Cancer Center in Tokyo on Dec. 23 for the first time published the five-year survival rates of patients with various cancers, ranging in age from children under 15 to adults under 40.
The five-year survival rate of children under 15 diagnosed with leukemia, a common childhood cancer, was 88 percent. Children with a brain tumor had a lower survival rate of 74.6 percent.
For those in the AYA (adolescent and young adult) generation, that is, people between the ages of 15 and 39, diagnosed with breast cancer, the survival rate was 90 percent. Breast cancer cases are high in the AYA age group.
Patients of the AYA generation diagnosed with cervical and uterine cancer showed a five-year survival rate of 89 percent.
Of the child patients, the five-year survival rate was highest in those with a germ cell tumor, at 96.6 percent, while it was lowest in children with a bone tumor, at 70.5 percent. For the AYA generation, those with thyroid cancer showed the highest survival rate, at 99.2 percent.
Five-year survival is the percentage of cancer patients who are still alive five years after diagnosis.
Support for younger cancer patients is needed because it is especially important for them to follow the disease course over a longer period of time.
The National Cancer Center calculated five-year survival rates by extracting data on children under 15 and children of the AYA generation from the data of approximately 880,000 patients diagnosed with cancer at a total of 437 hospitals in Japan in 2013 and 2014.
