Adolescents and young adults are less likely to survive some common cancers children, finds a new study on cancer survival across Europe.
“The good news is that the number of children, adolescents and young adults who survived for at least five years after diagnosis has increased steadily over time in Europe,” said lead author Annalisa Trama National Institute Cancer in Milan, Italy.
“However, we found that adolescents and young adults still tend to die earlier than boys for several common cancers in these age groups, especially blood cancers such as leukemia and non-Hodgkin lymphomas (NHL ), ‘said Trama Reading children with cancer are more likely to develop heart disease later in life
According to the researchers, variations in survival rates between the two age groups are due to a number of factors including delays in diagnosis and treatment, lack of guidelines treatment and clinical trials specifically for adolescents and young adults, as well as differences in the biology of some cancers.
For the study, published in the journal The Lancet Oncology , the researchers analyzed data from 27 European countries in almost 56 505 cases of cancer in children , 3,12,483 in adolescents and young adults and adults 35,67,383.
The results showed that, overall survival was significantly worse for teens and young adults compared with children of eight types of relatively common cancer affecting both age groups – lymphoid leukemias, acute myeloid leukemia, Hodgkin lymphoma, non-Hodgkin lymphoma (NHL), astrocytomas (type of brain tumor), bone Ewing sarcoma, rhabdomyosarcoma (cancer of soft tissues such as muscle) and osteosarcoma (the most common type of cancer bone).
However, for cancers with a better prognosis, survival rates five years found to be higher in adolescents and young adults by 82 percent compared to 79 percent in children . In addition, he found that teens and young adults to have a survival advantage over adults for almost all major types of cancer affecting both age groups, supporting the idea that younger patients with some other diseases are likely to perform better than older patients.
However, adolescents and young adults were found in survival disadvantage for cancer breast and prostate cancer . “This reflects the fact that younger women often have large cancers, higher grade who are more advanced, and that prostate disease tends to be more aggressive in younger men,” Trama said.
