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.

Acute lymphoblastic leukemia in adolescents and young adults.
Hematol Oncol Clin North Am. 2009 Oct;23(5):1033-42, vi
Authors: Ribera JM, Oriol A
Today, long-term survival is achieved in more than 80% of children 1 to 10 years old with acute lymphoblastic leukemia (ALL). However, cure rates for adults and adolescents and young adults (AYA) with ALL remain relatively low, at only 40% to 50%. Age is a continuous prognostic variable in ALL, with no single age at which prognosis deteriorates markedly....

Age disparities in thyroid cancer incidence and outcome among adolescents and young adults (AYAs) with thyroid cancer are under reported. In this study, the authors compared the molecular and clinical features of papillary thyroid cancer (PTC) in AYAs with the...

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...
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...
[Conversion of acute leukemia from a T-lymphoid to a myeloid phenotype].

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...

Two continuously growing in vito cell lines, PB-1049 and LN-1049, were established from a patient with Ph1-positive chronic myelogenous leukemia in extramedullary blastic crisis. PB-1049 was established from Epstein-Barr virus (EBV)-infected peripheral...
A tiger mouse and relatives. Variants caused by an activated transposable element?
J Hered. 1984 Jan-Feb;75(1):2-7
Authors: Wallace ME, Nash HR
In a laboratory-bred population of wild Peruvian house mice, one male had an excessive rate of non-pairing of the X and Y chromosomes. After crossing him with laboratory stock mice, a mouse of very unusual phenotype appeared from a yellow (AyA) mother. He was yellow with black dorsal stripes; hence Tiger. He was mated to many females, and inbred F2 and F3...
Interaction between Epstein-Barr virus and type-C virus in human cells.
IARC Sci Publ. 1978;(20):413-20
Authors: Osato T, Yamamoto K, Matsuo T, Aya T, Mizuno F, Nonoyama M
The interaction between EBV and type-C viruses was studied in our FVNC experimental system, in which EBV and type-C viral genomes are contained in each cell. The data indicate that the human lymphoid FVNC cells are sensitive to both EBV and type-C virus exposure, showing high frequencies of induction of both repressed viral...

Adolescents with acute lymphoblastic leukaemia: emerging from the shadow of paediatric and adult treatment protocols.
Pediatr Blood Cancer. 2006 Nov;47(6):748-56
Authors: Ramanujachar R, Richards S, Hann I, Webb D
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...
