This discussion reviews the current status of behavioral intervention
with adult and pediatric cancer patients. It begins by describing the
recent entry of behavioral research and practice into comprehensive ca
ncer treatment. The discussion then examines the use of behavioral pro
cedures to control aversive side effects of treatment. Although the co
ntrol of chemotherapy side effects is the primary focus (most of the b
ehavioral research on symptom control has dealt with reduction of naus
ea and vomiting with chemotherapy), the application of behavioral prin
ciples to other side effects (i.e., anxiety and pain) associated with
the aggressive treatment of cancer is assessed. The third topic is beh
avioral intervention to control child distress during invasive procedu
res. The discussion ends with a consideration of new directions of res
earch acid practice.
