Childhood cancer survivor studyChildhood cancer survivor study

Created to take advantage of: – The opportunity to gain new knowledge about the long‐

term effects of cancer and therapy, knowledge that can  be used to help design treatment protocols and 

intervention strategies that will increase survival and  minimize harmful health effects. 

– The obligation to educate survivors about the potential  impacts of cancer diagnosis and treatment on their 

health, and to provide follow‐up care, for example, by  treating and implementing programs for the prevention 

and early detection of late effects.

• On average, are childhood cancer survivors obese?

• Are childhood cancer survivors inactive?

• Why is a discussion of inactivity and obesity relevant for  childhood cancer survivors –

information from the 

Childhood Cancer Survivor Study?

• What are the characteristics of the survivors who are at  greatest risk for obesity and inactivity?

• Does diet play a role?

• Are there interventions available?

Page 49: Kirsten Ness, PT, PhD AICR October · Kirsten Ness, PT, PhD AICR. October 2010. The Questions • How many childhood cancer survivors are there? • On average, are childhood cancer

Summary• There are increasing numbers of childhood 

cancer survivors

• Childhood cancer survivors have altered body  composition

• They are inactive

• They are at increased risk for cardiac disease and  early death

• Cranial radiation, amputation, female gender,  and black race contribute to a poor outcome

Page 50: Kirsten Ness, PT, PhD AICR October · Kirsten Ness, PT, PhD AICR. October 2010. The Questions • How many childhood cancer survivors are there? • On average, are childhood cancer

Summary

• Altered body composition and inactivity are  correlated

• Social correlates include lower income and lower  educational attainment

• Smoking is associated with inactivity

• Dietary habits appear to be sub‐optimal

Page 51: Kirsten Ness, PT, PhD AICR October · Kirsten Ness, PT, PhD AICR. October 2010. The Questions • How many childhood cancer survivors are there? • On average, are childhood cancer

Summary

• Interventions are beginning to emerge

• There are problems with intervention  participation and retention

• Additional work is needed that addresses the  unique physical and cognitive needs of cancer  survivors

• Perceived barriers to change need to be  considered when designing interventions

• The interventions need to be portable

Childhood Cancer Survivor Study

The Childhood Cancer Survivor Study is an NCI‐ funded resource (U24 CA55727) to promote and 

facilitate research among long‐term survivors of  cancer diagnosed during childhood and 

adolescence.

Investigators interested in potential uses of this  resource are encouraged to visit:
