This review on psychological consequences of chemotherapies presents the research directions developed during the last two years: the first direction is a descriptive one and identifies the prevalence of psychological syndromes associated with these treatments. Besides psychological distress such as anxiety and depression, often underestimated in medical practice, some secondary cognitive deficiencies ought to be considered. It is also emphasized that the point of view of patients should be taken into account since their own assessment of the side effects is often discrepant with those of their medical providers. The second orientation developed here is the evaluation of actions aimed at controlling and alleviating the psychological consequences of these treatments by different protocols of information and psychotherapy. Good quality research is necessary in psycho-oncology in France and should be co-ordinated with clinical practice in psychology the offer of which is still too limited in our present health care system.
