Mental disorders were found to be rather frequent in patients with cancer undergoing radiotherapy.
Anxiety disorders were the most prevalent, followed by adjustment disorders and depression.
Besides being highly prevalent, these mental disorders were found to persist for at least a month after radiotherapy.
At the start of radiotherapy treatment, cancer patients presented a high frequency of emotional distress.
Sex, age, education status and previous surgery or chemotherapy were associated with the prevalence of mental disorders and distress.
These findings point to the need for assessment and psychological intervention in cancer patients undergoing radiotherapy.
