Effects of axillary dissection and breast irradiation on arm function. Evaluation based on QOL questionnaire survey

Complications and/or sequelae following breast cancer surgery such as arm edema on the affected side have serious deleterious effects on quality of life (QOL). Methods of therapy were classified into lumpectomy with or without axillary dissection and breast irradiation, lumpectomy+axillary dissection+breast irradiation, and modified mastectomy. A questionnaire survey was conducted on level of functional disorder of the arm. Results indicated that the present standard breast conservation therapy in which axillary dissection is followed by breast irradiation unfavorably affects QOL with respect to movement, numbness, pain and edema of the affected arm. Efforts should therefore be made after selection of indications to avoid either axillary dissection or breast irradiation. (author)
