Abstract

BackgroundWith prior reports indicating a lack of progress in survival improvement in older adolescents and young adults (AYAs) aged 15 to 39 years with cancer compared with both younger and older patients with cancer, the current analysis provides an update of survival trends of cancers among AYAs, children, and older adults.MethodsData from the National Cancer Institute Surveillance, Epidemiology, and End Results database for 13 regions were used to ascertain survival trends of the 34 most frequent cancers diagnosed in AYAs compared with children and older adults.ResultsAs of 2002 through 2006, the 5-year relative survival rate for all invasive cancers in AYAs was 82.5% (standard error, 0.2%). In AYAs, 14 cancers demonstrated evidence of a statistically significant improvement in their 5-year relative survival since 1992. Survival improved less in AYAs than in children for acute myeloid leukemia and medulloblastoma. Fourteen cancers had survival improvements that were found to be less in AYAs compared with older adults, including hepatic carcinoma, acute myeloid leukemia, high-grade astrocytoma, acute lymphocytic leukemia, pancreatic carcinoma, low-grade astrocytoma, gastric carcinoma, renal carcinoma, cancer of the oral cavity and pharynx, Hodgkin lymphoma, ovarian cancer, fibromatous sarcoma, other soft tissue sarcoma, and thyroid carcinoma.ConclusionsImprovements in the survival of several cancer types that occur frequently in AYAs are encouraging. However, survival does not appear to be improving to the same extent in AYAs as in children or older adults for several cancers. Further investment in exploring the distinct biology of tumors in this age group, and of their hosts, must be a priority in AYA oncology.

21. Children, cancer, and nutrition—A dynamic triangle in review

Author

Sala, Alessandra, Pencharz, Paul, and Barr, Ronald D.

Abstract

The overall cure rate for cancer in childhood now exceeds 70% and is projected to reach 85% by the year 2010 in industrialized countries. Therefore, major attention is being placed on reducing the side effects of therapy. However, 85% of the world's children live in developing countries, where access to adequate care often is limited and health status frequently is influenced adversely by prevalent infectious diseases and malnutrition. Despite several confounding factors (different definitions of nutritional status, the wide variety of measures used for its assessment, the selection biases by disease and stage, treatment protocols of variable dose intensity and efficacy, small sample sizes of the studies conducted in the last 20 years), it is accepted that the prevalence of malnutrition at diagnosis averages 50% in children with cancer in developing countries; whereas, in industrialized countries, it is related to the type of tumor and the extent of the disease, ranging from < 10% in patients with standard-risk acute lymphoblastic leukemia to 50% in patients with advanced neuroblastoma. The importance of nutritional status in children with cancer is related to its possible influence on the course of the disease and survival. Some authors have described decreased tolerance of chemotherapy associated with altered metabolism of antineoplastic drugs, increased infection rates, and poor clinical outcome in malnourished children. In this article, the authors review methods of nutritional assessment and the pathogenesis of nutritional morbidity in children with cancer as well as correlations of nutritional status with diagnosis, treatment, and outcome.
