Postoperative follow-up is the logical consequence of cancer treatment, but colorectal cancer follow-up does not achieve all its goals. These unfavourable findings induced us to assess whether follow-up also causes negative psychological stress in our colorectal cancer patients. In this trial 100 colorectal cancer follow-up patients were asked to compile three questionnaires: 1) the McGil Pain Questionnaires; 2) Profile of Mood Status; and 3) Locus of Control. The questionnaires were handed to the patients at follow-up and were compiled immediately. In addition, the patients were asked to answer the firsts two tests spontaneously 30 days after follow-up and mail the questionnaires. Our results showed that only 41% of the patients complied the tests 30 days after follow-up. The scores for pain and mood disorders were greater in women, especially during the "before follow-up" period. The third test revealed a prevalence of subjects with internal-type reinforcement. Our data revealed that: 1) patients tend to repress the problem; 2) women are affected by greater stress and anxiety; 3) subjects with internal-type reinforcement have a positive attitude during follow-up and this enables the ego to bear the anguish, process it and dilute it to anxiety, thus favouring future life experiences.
