149 testicular cancer patients with no evidence of disease for 3 or more years filled in a questionnaire which covered the following subjects: psychosocial well-being, working ability and use of analgesics/tranquilisers. The questions were chosen to compare cancer patients' morbidity with that of age-matched controls. The patients had been treated with surgery (32 patients), radiotherapy (39 patients), cisplatin-based chemotherapy plus surgery (46 patients) or chemotherapy plus radiotherapy with or without surgery (32 patients). Since no systematic differences between the treatment groups were found, the analyses were undertaken with all patients combined. The patients felt significantly less exhausted after a working day, were more satisfied with life and felt stronger and more fit than the controls. On the other hand, the patients reported a significantly higher incidence of anxiety and depression than the normal population. The results indicate that patients treated for a malignant disease may have greater fluctuations in mood and affect than the general population.
