Quality of life three months and one year after first treatment for early stage breast cancer: Influence of treatment and patient characteristics

This paper reports the quality of life (QoL) of a large cohort of Australia n women three and twelve months after surgery for early stage breast cancer (ESBC), and shows that the impact of disease and treatment on Qol, differe d by age, education and marital status. Eighty-three percent of eligible pa tients were recruited, 86% had breast conserving surgery and 14% mastectomy . Response rates were 93% (n = 305) at three months and 88% (n = 291) at on e year. Quality of life was measured with the EORTC core questionnaire (QLQ -C30) and an ESBC-specific questionnaire. Multilevel analysis was used to e stimate the effects and interactions of time, treatment and patient charact eristics. Most symptoms declined between three months and one year, but arm and menopausal symptoms persisted. Emotional, social and role functioning improved over time, and fear of disease recurrence diminished. Younger wome n faired worse than older women on a broad range of QoL dimensions. Single women and those with less education faired worse on a number of dimensions. The negative impact of mastectomy on body image was greatest among married women, particularly young married women. These sociodemographic distinctio ns are relevant when discussing treatment options with women facing a diagn osis of ESBC.
