Breast cancer morbidity: questionnaire survey of patients on the long term effects of disease and adjuvant therapy.

BACKGROUND: Many women have symptoms of various kinds after being treated for breast cancer. It is unclear how frequently these different side effects of treatment arise. METHOD: All women who underwent surgery for breast cancer and subsequently received adjuvant systemic treatment in a single certified breast-cancer center from 2006 to 2010 were asked to fill out a standardized questionnaire. Medical data were retrieved from their charts and statistically analyzed together with the questionnaire responses. The questionnaire was also given to an age-adjusted control group. RESULTS: 734 questionnaires were filled out and returned (response rate, 70%). The mean interval from the diagnosis of breast cancer to the time of response to the questionnaire was 38 months. The median age at time of response to the questionnaire was 65 years (range, 30 to 91 years). The distribution of UICC stages at the time of initial diagnosis was as follows: I 46%, II 42%, III 12%. 78% of the patients underwent breat conserving surgery, 85% had radio - therapy, 85% had antihormonal treatment, and 49% had chemotherapy. 91% were satisfied or very satisfied with the outcome of surgery. 34% reported operation site pain; 35% reported limitations of shoulder or arm function. Younger patients suffered from emotional sequelae more than older ones did. 25% reported a change in their relationship with their spouse. Before being diagnosed with breast cancer, 9% had consulted a psychiatrist or psychotherapist; after the diagnosis, 19% did. 14% had taken psychoactive medication before the diagnosis, and 26% did afterward. CONCLUSION: Treatment for breast cancer has negative physical, emotional, and social effects on many patients. They suffer these effects to varying degrees depending on age, type of surgery, and systemic treatment.
