Approximately 43,000 men and women were diagnosed with leukemia in the United States in 2009. The disease is unique in that it is common in both pediatric (<15) cancer patients and in older adult (>60) cancer patients. Of those diagnosed with leukemia, approximately 2600, or six percent, were diagnosed as adolescents or young adults (AYAs). Although there have been vast improvements in survival rates especially for pediatric leukemia, AYAs have not seen these same advancements. AYAs are often caught in the gap between pediatrics and adult cancers and different outcomes were seen in comparing treatments based on pediatric protocols versus adult protocols. Overall, adolescents treated on more aggressive pediatric protocols had improved overall and event-free survival.

INTRODUCTION: Cancer is rare in adolescents and young adults (AYA), but these patients have seen little improvement in survival in contrast to most other age groups. Furthermore, participation in research by AYAs is typically low. We...

Precursor B-Acute Lymphoblastic Leukemia (precursor B-ALL) occurs due to the uncontrolled proliferation of B-lymphoid precursors arrested at a particular stage of B-cell development. Precursor-B-ALL is classified mainly into pro-B-ALL, common-ALL and pre-B-ALL. The Common Acute Lymphoblastic...
Challenges in the recruitment of adolescents and young adults to cancer clinical trials.

The adolescent and young adult (AYA) oncology population has seen inferior progress in cancer survival compared with younger children and older adults over the past 25 years. Previously, AYAs had the best survival rates due to the prevalence of highly curable diseases including Hodgkin lymphoma and germ cell tumors, yet today AYAs have...
Adolescent and young adult (AYA) oncology: the first A.
Pediatr Hematol Oncol. 2007 Jul-Aug;24(5):325-36
Authors: Bleyer A
Whereas adolescents with cancer as a group used to have a better prognosis than children with malignant disease, trends suggest that the overall survival of 15- to 19-year-olds is now worse than in younger patients. Also, the incidence of cancer is higher in 15- to 19-year age span than during the first 15 years of life. In 2006, the U.S. National Cancer Institute (NCI) and the...

A 7-year-old girl with an acute leukemia was reported whose blasts showed conversion from a T-lymphoid to a myeloid phenotype. At the onset of the disease, the blasts were negative for peroxidase and displayed FAB L1 morphology. Surface marker analysis revealed only CD7 antigen....

We report a 17-year-old female with chronic myeloid leukemia (CML) who developed monocytic crisis. She was diagnosed as chronic phase of Ph1-chromosome positive CML at 14 years old. Three years after the diagnosis of the disease, she was admitted to the hospital because of low grade fever, lethargy...

Adolescents and young adults (AYA) with acute lymphoblastic leukaemia (ALL) constitute a distinct population from children and older adults. Based on patterns of referral, they may be treated by either paediatric or adult oncologists. As a group, AYA with ALL have a worse survival and...
