Twenty-eight patients cured of testicular cancer by cisplatin-based chemotherapy were asked for their own views of the long-term psychological and social effects of their treatment. Their views were compared with a group of 34 testicular cancer patients cured by radiotherapy who were matched for age, social class and time since treatment. A category rating type questionnaire was used with questions concerning general health, subjective side-effects of treatment, employment, relationships, reproduction and mood. The principal differences were (1) the chemotherapy group reported a greater prevalence of physical side-effects, (2) the radiotherapy group reported greater anxiety and depression since treatment and (3) a significant number of patients in the chemotherapy group felt that their illness had had beneficial effects on their relationships with family and friends.
