Analysis of Factors Associated with Quality of Life in Breast Cancer Patients after Surgery.

The objective of this study was to investigate the factors associated with the quality of life (QOL) in breast cancer patients after surgery. The QOL in 83 primary breast cancer patients after surgery was prospectively assessed using a newly developed Japanese QOL questionnaire: The QOL Questionnaire for Cancer Patients Treated with Anticancer Drugs (QOL-ACD). The demographic and medical factors relating to the QOL score in the subjects were investigated by multiple regression analyses. Factors related to the four categories of the QOL-ACE (activity, physical condition, psychological condition, and social relationship) were also analyzed. The results revealed that only hospitalization had a strong negative relation to the overall QOL score. With regard to the four categories of the QOL-ACE, hospitalization had strong negative relations to the three categories (activity, physical condition and social relationship) and had weak negative relation to the psychological condition. Other demographic and medical factors such as types of surgery or adjuvant therapy had no significant association with the QOL score, except for the performance status which had positive, but not significant, association with the activity. In conclusion, this study yielded useful information concerning the management of the breast cancer patients after surgery. We had better be more concerned with the hospitalized period than other demographic or medical factors such as types of therapy to improve the QOL.
